Sponsor Licence Changes to Ownership & Control | UK Guide

Sponsor Licence Changes to Ownership & Control: At a Glance

A change in the ownership or control of a business can affect its UK sponsor licence even where the sponsoring company remains the same legal entity and continues employing the same workforce. Share sales, management buyouts, investment transactions and group restructurings should therefore be assessed for their sponsorship consequences before completion.

Relevant changes in direct ownership, including transfers of controlling shares or changes to the sponsor’s immediate ownership, can require a new sponsor licence. Changes higher in the corporate chain can be treated differently, particularly where the sponsor’s immediate owner, business operations and sponsored employment arrangements remain unchanged.

The corporate structure should therefore be examined before and after the transaction. Retaining the same company number, trading name, workforce or ultimate owner does not, by itself, establish that the existing sponsor licence can continue.

Relevant ownership and corporate changes generally have to be reported to the Home Office within 20 working days. Certain transactions also trigger a separate requirement to apply for a new sponsor licence within 20 working days. For an ownership-change request made through the relevant Sponsor Management System function, the submission sheet and any required supporting evidence must be provided within 5 working days.

Sponsored workers also need to be considered. A share sale may leave their legal employer unchanged while still affecting the licence supporting their employment. Where workers transfer to another organisation, the receiving employer needs to establish its sponsor licence position and whether the Home Office provisions for TUPE or similar protection allow existing immigration permission to continue.

This guide explains how changes in direct and indirect ownership affect sponsor licences, when a new licence may be required, the reporting and application deadlines, the position of sponsored workers and the compliance steps employers should build into acquisitions, restructurings and other changes of control.

 

Section A: Sponsor Licence Changes to Ownership & Control: Key Rules

 

The sponsor licence consequences of an ownership transaction depend on where control changes within the corporate structure, whether the licensed legal entity remains the employer of sponsored workers and whether the transaction engages the Home Office rules on direct ownership, business transfers or other corporate changes.

Employers should start with the legal and corporate structure of the transaction, not its commercial label. A share sale, management buyout, insertion of a new holding company and acquisition of an ultimate parent can produce different sponsorship outcomes even where the underlying business continues operating without interruption.

 

1. When Can a Change in Direct Ownership Require a New Sponsor Licence?

 

A relevant change in direct ownership can require a new sponsor licence even where the sponsoring company remains the same incorporated legal entity.

Under section C4 of the Home Office Workers and Temporary Workers sponsor guidance, a transfer of controlling shares can engage the direct ownership provisions. The guidance includes an example in which a company continues trading and employing the same workforce after its controlling shares are transferred, but is required to report the change and apply for a new sponsor licence within 20 working days.

The continued existence of the company is therefore only one part of the assessment. Employers should establish who directly owns or controls the licensed sponsor before and after completion and whether the transaction falls within the relevant Home Office provisions.

 

2. How Are Direct and Indirect Ownership Changes Treated?

 

Ownership can change at different levels of a corporate group, and the Home Office does not apply the same licensing outcome to every change.

A direct ownership change can arise where shares in the licensed sponsor are transferred or a new immediate holding company is introduced. An indirect ownership change may occur further up the corporate chain while the sponsor’s immediate owner remains unchanged.

Where only the ultimate parent changes and the sponsor’s immediate ownership, operations and sponsored employment arrangements remain unchanged, the Home Office guidance indicates that reporting may be required without necessarily requiring a replacement licence.

The position can be different where a new immediate holding company is inserted into the structure, even where ultimate ownership remains unchanged. Employers should therefore compare the full corporate structure before and after completion rather than relying on whether ultimate beneficial ownership has changed.

 

3. Can a Sponsor Licence Transfer to Another Company?

 

A sponsor licence belongs to the organisation to which it was granted and cannot simply be assigned to another legal entity through a share purchase agreement, asset purchase agreement or restructuring document.

Where a transaction moves sponsored workers to another employing entity, the receiving organisation needs to establish whether it already holds the appropriate sponsorship authorisation or needs to obtain it.

This commonly arises in business and asset sales, mergers and intra-group transfers. Common ownership does not allow one group company to rely automatically on another company’s sponsor licence.

 

4. What Are the Reporting and Application Deadlines?

 

Relevant changes in ownership and corporate circumstances covered by section C4 generally have to be reported within 20 working days.

Certain transactions also require a new sponsor licence application within a separate 20-working-day period. Reporting the ownership change does not satisfy the application requirement, and submitting a new licence application does not necessarily discharge the sponsor’s other reporting duties.

For an ownership-change request made through the relevant SMS function, the sponsor must also complete and send the submission sheet, together with any required supporting evidence, within 5 working days.

Employers should identify the trigger date for each obligation before completion and allocate responsibility for the report, application and supporting evidence separately.

 

5. What Happens to Sponsored Workers After an Ownership Change?

 

The effect on sponsored workers depends on whether their legal employer changes and what happens to the sponsor licence supporting their employment.

In a share sale, employees may remain with the same legal entity while the direct ownership change affects the company’s licence. Where workers move to a different employer, the receiving organisation needs to establish its own sponsorship position.

For qualifying transfers, including those covered by TUPE or similar protection, existing immigration permission may be able to continue without a new Certificate of Sponsorship or visa application. The relevant conditions include the receiving organisation holding or obtaining the necessary sponsor licence, accepting sponsorship responsibility and the worker continuing in the same sponsored occupation code without a material change taking the role outside the existing sponsored employment.

Employers should assess the sponsored workforce before completion and identify any workers whose post-transaction employment arrangements require additional immigration action.

 

6. Can New Owners or Management Affect Sponsor Suitability?

 

Ownership transactions can introduce new controlling shareholders, directors, senior managers and individuals responsible for sponsor compliance.

The Home Office can take account of ownership, management, relevant individuals and the organisation’s ability to meet its sponsor duties when assessing suitability. Employers should therefore review the incoming ownership and management structure alongside any changes to sponsor key personnel.

The assessment should also confirm that appropriate individuals will remain in place to manage the sponsor licence, access the SMS and respond to Home Office enquiries after completion.

 

7. How Does a Change of Ownership Affect Right to Work Compliance?

 

Sponsor licence compliance and the statutory right to work regime impose separate obligations.

A change of ownership does not automatically require fresh right to work checks where the same legal entity continues employing the workforce. Employers should nevertheless verify that existing checks and follow-up arrangements remain compliant.

Where workers transfer to another employer, the applicable statutory excuse and checking requirements should be assessed separately. Since 1 October 2026, the prescribed framework also extends to specified worker contracts and individual subcontractor arrangements, increasing the scope of workforce compliance due diligence in some acquisitions and restructurings.

Right to work records, outstanding follow-up checks and responsibility for post-completion compliance should therefore form part of the wider transaction review.

 

8. What Should Employers Establish Before Completion?

 

The sponsor licensing position should be settled before the parties commit to a transaction structure or completion timetable that cannot accommodate the required Home Office action.

Employers should identify the licensed sponsor, direct and indirect ownership before and after completion, any change to the employing entity, the affected sponsored workforce and the sponsor licence position of any receiving organisation.

The transaction plan should then record any reporting or licence application requirements, the relevant 20-working-day deadlines, the separate five-working-day evidence requirement where applicable, changes to key personnel and the right to work responsibilities arising after completion.

For transactions involving several entities, clear corporate structure charts and a worker-level immigration schedule provide the strongest basis for allocating responsibility and managing the post-completion sponsorship position.

Section B: What Counts as a Change of Ownership or Control?

 

A change of ownership or control can arise in several ways, and the immigration consequences depend on how the transaction affects the organisation holding the sponsor licence.

For sponsor licensing purposes, employers need to distinguish between a change in the company’s direct ownership, a change in its ultimate or indirect ownership, changes in the individuals controlling or managing the business, and transactions involving a different legal entity becoming responsible for sponsored workers.

These distinctions are important because the Home Office does not necessarily treat all corporate transactions in the same way. A change in direct ownership can require a new sponsor licence even where the same company continues trading. By contrast, certain changes higher in a corporate ownership chain may require notification without necessarily requiring a replacement licence.

The legal structure of the transaction is therefore more important than its commercial description. Terms such as takeover, acquisition, investment, merger and restructuring are frequently used interchangeably in business discussions, but they can describe transactions with materially different sponsor licensing consequences.

Employers should establish the precise ownership and employment arrangements before and after the proposed change, rather than relying on assumptions about whether the business will continue operating as before.

 

1. Changes in company shareholders

 

A change in shareholders occurs where shares in a company are transferred, sold, issued or otherwise redistributed between existing or new investors.

Shareholder changes may involve a relatively small investment, the acquisition of a controlling interest or the transfer of all the shares in a company to a new owner.

In a conventional share sale, the company itself ordinarily continues to exist as the same legal entity. Its assets, contracts and employment relationships generally remain with that company, although the ownership of the company changes.

However, the continuation of the legal entity does not mean that the sponsor licence necessarily continues unaffected.

Section C4 of the Home Office Workers and Temporary Workers sponsor guidance addresses changes in ownership and contains specific requirements for relevant direct ownership changes.

The guidance includes an example involving the transfer of controlling shares to a new individual. Although the company continues trading as before, the transaction requires notification to the Home Office and a new sponsor licence application within 20 working days.

This means employers cannot rely solely on the corporate law principle that a share sale does not change the company’s legal identity.

The sponsor licensing assessment should establish:

 

• Which shareholders hold shares before and after the transaction.
• Whether the transaction changes direct ownership or control of the licensed organisation.
• Whether the transaction involves the transfer of a controlling shareholding.
• Whether the sponsor’s immediate parent company changes.
• Whether the relevant Home Office provisions require a new sponsor licence application.
• What reporting obligations arise and when the applicable deadlines begin.
• Whether the ownership change affects the organisation’s continuing sponsor suitability.

 

Not every movement in a company’s share register should automatically be treated as having the same licensing consequences. The nature and effect of the change must be assessed against the applicable sponsor guidance.

For example, a small investment that does not alter control may present different issues from the acquisition of a majority shareholding. The existence of different commercial arrangements does not remove the need to assess whether the relevant Home Office ownership provisions apply.

Where a company is planning a substantial share transaction, the sponsor licensing implications should be established before completion so that any required application can be incorporated into the transaction timetable.

 

2. Changes in controlling shareholders or beneficial ownership

 

Control of a company does not always depend exclusively on the percentage of shares held by an individual or corporate investor.

Shareholders may exercise control through voting rights, shareholder agreements, rights to appoint directors or other arrangements that influence the company’s management and strategic decisions.

In more complex ownership structures, the individuals or organisations exercising ultimate control may be several levels removed from the company holding the sponsor licence.

Employers should therefore consider both legal ownership and the practical arrangements through which control is exercised.

For example, an investor may acquire rights allowing it to determine important corporate decisions without acquiring all the company’s shares. Alternatively, existing shareholders may enter into arrangements that materially alter the balance of control without an obvious change in the company’s trading activities.

The employer should establish whether these arrangements constitute a relevant change under the sponsor guidance and whether they affect the information previously provided to the Home Office.

Companies House records concerning persons with significant control can assist with this assessment. However, the statutory framework for recording persons with significant control should not automatically be treated as identical to the tests applied under Home Office sponsor licensing rules.

The immigration assessment should be based on the actual transaction and the applicable Home Office requirements, rather than relying solely on whether a Companies House filing has been made.

Where beneficial ownership is held through several companies, trusts or other arrangements, the employer may need to obtain further information to identify the relevant controlling interests.

This can be particularly important where the acquisition introduces individuals or organisations whose background may be relevant to sponsor suitability.

A change in controlling ownership should therefore be assessed for both its immediate licensing consequences and any wider implications for the organisation’s ability to meet its sponsor duties.

 

3. Changes to the parent company or corporate group

 

Many licensed sponsors operate as subsidiaries within larger UK or international corporate groups.

In these arrangements, the company holding the sponsor licence may be owned directly by another company, which is itself owned by one or more additional entities.

Changes in ownership can occur at different levels of this structure.

A transaction may change the sponsor’s immediate parent company, its ultimate parent company or both. The distinction is important because the Home Office guidance recognises different licensing consequences depending on where the change occurs.

Change of ultimate parent company

Where a UK sponsoring company remains owned by the same immediate parent but the ownership of that parent changes further up the corporate chain, the transaction may constitute a change in indirect ownership or ultimate control.

The Home Office guidance provides an example in which the ultimate parent changes while the sponsor’s immediate ownership and relevant business arrangements remain unchanged. In that scenario, the change must be reported, but a new sponsor licence is unlikely to be required where the relevant conditions are satisfied.

Employers should not interpret this example as a general exemption for all indirect ownership changes. The precise corporate structure and transaction must be considered.

Change of immediate parent company

A different position can arise where the sponsoring company receives a new immediate holding company.

The Home Office guidance includes an example in which a new immediate holding company is inserted into a corporate structure even though the ultimate owner remains unchanged. The example requires a new sponsor licence.

This illustrates that the absence of a change in ultimate beneficial ownership does not necessarily mean that the sponsor licensing position remains unchanged.

Group reorganisations

Internal reorganisations may involve transferring shares between group companies, creating new holding companies, combining subsidiaries or moving operations between legal entities.

Although the ultimate commercial owners may remain the same, the restructuring can still affect the sponsor’s direct ownership or the legal entity employing sponsored workers.

Employers should prepare corporate structure charts showing the position before and after the proposed reorganisation.

The assessment should identify the licensed sponsor, its immediate and ultimate parents, the relevant changes in control and any movement of sponsored employees between group companies.

Common group ownership does not automatically permit one company to rely on another company’s sponsor licence. Each organisation’s position must be assessed separately.

 

4. Changes in directors and management

 

Changes in directors and senior management are not necessarily changes in company ownership. However, they can create separate sponsor licence reporting, suitability and operational compliance obligations.

A company may appoint new directors following an investment, replace its management team after an acquisition or reorganise responsibility for immigration compliance within the business.

These changes should be assessed independently of any share transaction.

For example, a new director may be appointed without any change in the company’s shareholders. Conversely, a new shareholder may acquire control without immediately replacing the existing directors.

The Home Office may require relevant changes in organisational information or sponsor key personnel to be reported through the appropriate procedures.

Employers should pay particular attention to the individuals responsible for managing the sponsor licence, including the Authorising Officer, Key Contact and Level 1 Users.

If an acquisition results in the departure of the existing Authorising Officer, the business must ensure that responsibility is transferred appropriately and that the relevant Home Office requirements are satisfied.

Similarly, where individuals with Sponsor Management System access leave the organisation, their access and permissions should be reviewed.

Failure to maintain appropriate sponsor management arrangements can create compliance difficulties even where the ownership transaction itself has been correctly reported.

Employers should also consider whether newly appointed directors or other relevant individuals raise issues under the Home Office sponsor suitability requirements.

This may be particularly important where an individual has previously been involved in sponsor licence revocation, immigration non-compliance or other matters relevant to the suitability assessment.

Not every management appointment requires a new sponsor licence. The correct approach is to distinguish between the consequences of the ownership transaction and the separate obligations arising from changes in personnel.

 

5. Ownership changes versus changes in legal entity

 

One of the most important distinctions in sponsor licence compliance is the difference between a change in the ownership of a company and a change in the legal entity employing sponsored workers.

The two can produce very different immigration consequences.

Share acquisition

In a conventional share acquisition, the buyer purchases shares in the company. The company generally remains the same incorporated legal entity and continues to hold its contracts and employ its workforce.

For example, Company A holds a sponsor licence and employs several Skilled Workers. An investor purchases the controlling shares in Company A.

Company A may remain the legal employer of those workers after completion. However, the change in direct ownership can still trigger a requirement to report the transaction and apply for a new sponsor licence under the relevant Home Office provisions.

The fact that employees have not changed employer does not remove the need to address the sponsor licensing consequences.

Business or asset acquisition

In a business or asset acquisition, the buyer purchases specified assets or operations rather than shares in the company that owns them.

Employees may transfer from the selling organisation to the buyer or another receiving entity.

For example, Company A sells a division of its business to Company B. Sponsored workers employed within that division transfer to Company B as part of the transaction.

Company B becomes responsible for the employees, but it cannot simply acquire Company A’s sponsor licence as part of the asset purchase.

The parties must establish Company B’s sponsor licensing position and assess the Home Office provisions governing the transfer of sponsored workers.

Where the transfer falls within the relevant provisions for TUPE or similar protection, the workers may be able to continue without a new immigration application or Certificate of Sponsorship, provided the applicable conditions are met.

The receiving organisation must hold or obtain the necessary sponsor licence and accept responsibility for sponsorship in accordance with the Home Office requirements.

Corporate mergers and reorganisations

Mergers and reorganisations can involve changes in both ownership and employing entity.

A merger may result in one company acquiring another, two businesses combining under a new legal entity or employees moving between existing group companies.

The commercial label attached to the transaction does not determine the immigration position.

Employers must establish which legal entities exist before and after the transaction, which organisations hold sponsor licences and which entities will employ the sponsored workers.

Where the transaction involves several sponsoring companies, each licence and affected workforce should be considered separately.

The legal entity analysis is also relevant to right to work compliance. Following the changes effective from 1 October 2026, employers should consider not only traditional employees but also workers and individual subcontractors falling within the expanded prescribed checking framework.

Where the responsible employer changes, the parties should establish the applicable right to work checking and statutory excuse requirements. This assessment is separate from the question of whether a sponsor licence continues or a new licence is required.

 

6. How employers should identify the relevant change

 

Before determining the sponsor licence consequences of a transaction, employers should establish the relevant corporate and employment facts.

The assessment should identify:

 

1. The licensed organisation: the full legal identity of the company or other organisation holding the sponsor licence.
2. Existing direct ownership: the shareholders or immediate parent company before the transaction.
3. Proposed direct ownership: the shareholders or immediate parent company following completion.
4. Ultimate ownership and control: any changes further up the corporate ownership chain.
5. Management arrangements: changes in directors, senior managers and sponsor key personnel.
6. Employing entities: whether sponsored workers remain employed by the same organisation or transfer to another legal entity.
7. Existing sponsor licences: whether the acquiring or receiving organisations already hold the relevant licences.
8. Sponsored workforce: the employees affected by the transaction and their existing immigration arrangements.
9. Right to work responsibilities: the organisation responsible for prescribed checks and records, including relevant worker and individual subcontractor arrangements.
10. Home Office action: whether the transaction requires notification, a new sponsor licence application or additional worker-related action.

 

Employers should retain an accurate record of the assessment, including the corporate structure charts, relevant transaction documents and the basis on which the applicable Home Office requirements were identified.

Where the transaction involves a direct ownership change, the assessment should specifically address the new licence requirements in section C4 of the sponsor guidance and the applicable 20-working-day deadlines.

Where the transaction involves indirect ownership changes or group restructuring, the employer should establish whether the relevant Home Office examples and requirements support continuation of the existing licence or require a different outcome.

The objective is to identify the actual legal and immigration consequences of the transaction before completion, rather than relying on assumptions about business continuity.

Section C: Does a Change of Ownership Affect an Existing Sponsor Licence?

 

A change in the ownership or control of a sponsoring organisation can affect the status of its existing sponsor licence, even where the business continues operating under the same name, employing the same workers and carrying out the same activities.

The Home Office applies specific rules to changes in ownership, mergers, takeovers and business transfers. These rules are set out in section C4 of the Workers and Temporary Workers sponsor guidance and distinguish between different forms of corporate transaction.

In particular, a change in direct ownership can trigger a requirement to apply for a new sponsor licence, even where the company remains the same incorporated legal entity. Certain indirect ownership changes may be treated differently, while transactions involving a transfer of sponsored workers to another employing organisation create additional licensing and immigration considerations.

Employers should not assume that the existing licence automatically continues because the company retains its Companies House registration, trading name, premises or workforce.

Equally, the requirement for a new licence should not be applied indiscriminately to every change in shareholders or corporate structure. The actual transaction must be assessed against the relevant Home Office provisions.

The central questions are whether the transaction changes the sponsor’s direct ownership, whether it affects the legal entity responsible for sponsorship and whether the Home Office requires a new licence application or other action.

 

1. Where the sponsoring legal entity remains the same

 

In a conventional share acquisition, the purchaser acquires shares in an existing company rather than purchasing its business and assets directly.

The company generally continues to exist as the same legal entity. Its employment contracts, commercial agreements and other obligations ordinarily remain with that company.

However, the continuation of the same legal entity does not automatically preserve the company’s sponsor licence.

The Home Office sponsor guidance expressly addresses changes in direct ownership and provides examples in which a company must apply for a new sponsor licence following a transfer of controlling shares, despite continuing to trade and employ its workforce as before.

For example, Company A holds a Skilled Worker sponsor licence and employs a number of sponsored workers. An individual purchases the controlling shares in Company A.

Following completion, Company A remains incorporated, continues trading from the same premises and retains the same employment contracts.

Nevertheless, the transaction can constitute a relevant change in direct ownership under the Home Office guidance. In the example provided by the guidance, the company is required to report the change and apply for a new sponsor licence within 20 working days.

This demonstrates that corporate continuity and sponsor licence continuity are separate legal questions.

Before completion, employers should establish:

 

• Whether the transaction constitutes a relevant change in direct ownership.
• Whether the existing sponsor licence will be affected by the change.
• Whether a new sponsor licence application is required.
• The applicable reporting and application deadlines.
• Whether the new ownership arrangements raise sponsor suitability concerns.
• How the immigration position of existing sponsored workers will be managed.
• Whether changes to directors or sponsor key personnel create additional reporting obligations.

 

The share purchase agreement may provide for the uninterrupted operation of the company, but contractual arrangements between the buyer and seller cannot override Home Office sponsor licensing requirements.

 

2. Direct ownership changes requiring a new sponsor licence

 

A direct ownership change can occur where controlling shares in a sponsoring organisation are transferred to a new owner or where the sponsor’s immediate corporate ownership changes.

Under the Home Office sponsor guidance, relevant changes in direct ownership can require a new sponsor licence application.

The guidance includes a scenario in which a company transfers its controlling shares to an individual but otherwise continues trading unchanged. The company must report the change and apply for a new sponsor licence within 20 working days.

Another example concerns the introduction of a new immediate holding company into a corporate group. Even where the ultimate parent company remains unchanged, the alteration in direct ownership can require a new sponsor licence.

These examples illustrate that the Home Office assessment is not determined solely by whether the ultimate economic owners have changed or whether the business continues to operate in the same manner.

Employers must establish the identity of the sponsor’s immediate owner before and after the transaction and determine whether the change falls within the relevant provisions.

Where a new application is required, the organisation must satisfy the applicable sponsor licence eligibility and suitability requirements.

The application is not simply an administrative update to the existing licence. It involves the Home Office assessing the organisation’s entitlement to hold the relevant sponsorship authorisation.

Employers should therefore consider the evidence required, the availability of appropriate sponsor key personnel and the organisation’s ability to demonstrate compliance with its sponsorship obligations.

The requirement should be identified before completion wherever possible. Failure to account for a new licence application can create significant uncertainty for the business and its sponsored workforce.

 

3. Indirect ownership changes and ultimate parent companies

 

Changes in indirect ownership can arise where the sponsor’s immediate shareholder remains unchanged but control changes further up the corporate ownership chain.

This is common in international acquisitions and group restructurings involving several holding companies.

For example, Company A is a UK licensed sponsor wholly owned by Company B. Company B is itself owned by Company C.

If Company C is acquired by another organisation, Company A may remain directly owned by Company B, even though its ultimate parent company changes.

The Home Office guidance provides an example of an ultimate parent company changing while the sponsor’s immediate ownership, business operations and sponsored employment arrangements remain unchanged.

In that example, the change must be reported, but a new sponsor licence is unlikely to be required where the relevant conditions are satisfied.

This does not mean that all indirect changes in control are exempt from new licence requirements.

Employers should examine the complete corporate structure, identify the actual changes in ownership and control, and establish whether the transaction is consistent with the circumstances addressed in the Home Office guidance.

The position can be different where the transaction changes the immediate holding company rather than merely the ultimate parent.

For example, the insertion of a new company between the sponsor and its existing parent may constitute a direct ownership change requiring a new licence, even though the ultimate owner remains the same.

Employers should not therefore assume that an internal group restructuring is immigration-neutral merely because there is no change in the ultimate beneficial ownership of the business.

Clear pre-completion and post-completion corporate structure charts are particularly important when assessing indirect ownership changes.

 

4. Where the employing legal entity changes

 

A different set of considerations arises where a transaction results in sponsored workers becoming employed by another legal entity.

This can occur through a business or asset sale, merger, transfer of undertaking, outsourcing arrangement or intra-group restructuring.

In these circumstances, the organisation responsible for employing and sponsoring the workers may change, even where the business continues operating from the same premises and performing the same activities.

A sponsor licence cannot simply be assigned to the receiving employer as part of the transaction.

The receiving organisation must establish whether it already holds the appropriate sponsor licence or needs to obtain one under the relevant Home Office provisions.

For example, Company A holds a sponsor licence and operates a business employing sponsored Skilled Workers. Company B purchases the business and becomes the employer of those workers.

Company B cannot automatically rely on Company A’s sponsor licence merely because it has acquired the business and assumed responsibility for the employees.

The parties must assess the sponsor licensing requirements applicable to the transfer and determine how the workers’ existing immigration arrangements can continue.

Where the transaction qualifies for the relevant Home Office provisions concerning TUPE or similar protection, the workers may be able to continue without making new immigration applications or obtaining new Certificates of Sponsorship, provided the applicable conditions are met.

These conditions include the receiving organisation holding or obtaining the necessary licence, accepting responsibility for sponsorship and the workers continuing in the same sponsored occupation code, with no material change taking the role outside the existing sponsored employment.

The Home Office guidance provides specific application periods for receiving organisations that need a licence or an extension to an existing licence. In relevant circumstances, the application must be made within 20 working days.

Employers should not assume that employment law protections automatically establish compliance with immigration sponsorship requirements.

The employment law position and the Home Office sponsor licensing position must be considered together, but each has its own requirements.

 

5. When a new sponsor licence application is required

 

A new sponsor licence application may be required following a relevant change in direct ownership, a change in the employing legal entity or another corporate transaction falling within the applicable Home Office provisions.

The requirement must be determined by reference to the specific transaction and the sponsor guidance in force at the relevant time.

Employers should not rely solely on whether the purchaser already operates other sponsored businesses or whether the transaction takes place within an existing corporate group.

A sponsor licence held by one company does not automatically authorise every other company under common ownership to sponsor workers.

Where a new application is required, the organisation should establish:

 

1. The applicant: which legal entity is required to apply for the sponsor licence.
2. The relevant sponsorship routes: whether the organisation requires authorisation under the Skilled Worker route or other applicable routes.
3. The application deadline: whether the transaction engages the relevant 20-working-day application requirement.
4. Eligibility: whether the applicant meets the Home Office requirements for holding a sponsor licence.
5. Suitability: whether the ownership, management and compliance arrangements satisfy the applicable requirements.
6. Supporting evidence: which corporate, trading and operational documents must be submitted.
7. Key personnel: who will act as Authorising Officer, Key Contact and Level 1 User.
8. Sponsored workers: how existing employees will be sponsored following the transaction.
9. Reporting: which notifications must be submitted separately from the licence application.
10. Operational continuity: how the business will manage sponsorship responsibilities while the Home Office considers the application.

 

Where the Home Office requires a new application within 20 working days, the employer should not assume that the deadline can be extended simply because the transaction is commercially complex or supporting evidence is difficult to obtain.

Equally, submitting an application does not guarantee that the Home Office will grant the licence.

The organisation must satisfy the relevant requirements, and the Home Office may seek further information or undertake compliance checks before reaching a decision.

Transaction planning should therefore account for both the application deadline and the possibility that the licensing process may require further evidence or scrutiny.

 

6. Why a sponsor licence cannot simply be transferred to a buyer

 

A sponsor licence is an authorisation granted by the Home Office to a particular organisation following an assessment of its eligibility, suitability and ability to comply with sponsorship duties.

It is not equivalent to a commercial contract, intellectual property right or business asset that can ordinarily be transferred by agreement.

Where a purchaser acquires a business, the purchase agreement cannot independently transfer the seller’s sponsor licence to the buyer.

Similarly, a corporate group cannot assume that sponsorship authorisation follows employees or business operations when they are moved between subsidiaries.

The Home Office must be able to identify the organisation responsible for each sponsored worker and establish that the organisation is authorised to sponsor under the relevant immigration route.

This is particularly important where a transaction involves several entities, including a holding company, trading company, employing company and service company.

The commercial purchaser may not be the same organisation that becomes responsible for employing sponsored workers.

Employers should therefore distinguish between the entity acquiring shares or assets and the entity that will actually employ and sponsor the workers.

Where the transaction changes the sponsor’s legal identity or the employing organisation, the parties must comply with the relevant Home Office provisions rather than relying on contractual transfer arrangements.

 

7. What happens to the existing licence following a relevant ownership change?

 

The Home Office guidance provides for different outcomes depending on the nature of the transaction and the circumstances of the sponsor.

Where the transaction constitutes a relevant change in direct ownership under C4.5, the existing sponsor licence will be revoked or, where sponsored workers have transferred under the relevant arrangements, made dormant.

These outcomes should not be confused with revocation following a serious breach of sponsor duties.

A licence may be affected because the corporate transaction changes the organisation’s licensing position, rather than because the employer has committed misconduct.

However, failure to comply with the applicable reporting, application or sponsorship requirements can create separate compliance concerns and may expose the organisation to Home Office action.

Employers should establish the intended licensing outcome and ensure that any necessary applications or notifications are completed within the required periods.

Where the Home Office makes a licence dormant, the employer should not assume that the licence remains available for ordinary sponsorship activity.

The precise effect of the licence’s status and the arrangements for sponsored workers must be established from the applicable Home Office decision and guidance.

Where a licence is revoked or a required replacement application is refused, the consequences can extend to workers whose immigration permission depends on sponsorship by the affected organisation.

The employer should therefore treat licence continuity as a material transaction risk rather than a routine administrative matter.

 

8. Consequences of failing to obtain a required licence

 

Failure to obtain a sponsor licence where one is required can have serious consequences for the organisation and its sponsored workforce.

Where a receiving organisation is required to apply for a licence following a qualifying business transfer, the Home Office guidance provides specific application requirements and deadlines.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

For a business that depends on sponsored employees, this can create substantial operational difficulties.

Potential consequences include uncertainty over the continued employment of sponsored workers, disruption to recruitment, additional compliance scrutiny and restrictions on the organisation’s ability to sponsor new employees.

The precise consequences depend on the transaction, the status of the relevant licences and the Home Office decisions affecting the organisations and workers involved.

Employers should not assume that a missed application deadline can be corrected retrospectively without immigration consequences.

Where a transaction has already completed and the required licensing action was not taken, the organisation should promptly establish its current position and obtain advice on the appropriate steps.

It should also assess whether any continued sponsorship activity, including the assignment of Certificates of Sponsorship, is permitted under the organisation’s actual licensing status.

 

9. Sponsor licence continuity and right to work compliance

 

The status of a sponsor licence and the employer’s right to work obligations are related but separate legal issues.

An organisation may need to take action concerning its sponsor licence following an ownership transaction while also ensuring that it complies with the prescribed right to work checking requirements applicable to its workforce.

The right to work framework was amended with effect from 1 October 2026, extending prescribed checking obligations to specified worker contracts and individual subcontractor arrangements in addition to conventional employment relationships.

Employers involved in acquisitions and reorganisations should therefore consider the scope of their workforce and the identity of the organisation responsible for right to work compliance after completion.

Where a share acquisition leaves the employing legal entity unchanged, the ownership change does not automatically require every employee to undergo a fresh right to work check.

On a qualifying TUPE transfer, the incoming employer obtains the benefit of any statutory excuse established by the outgoing employer, but can inherit exposure where the original check was defective. The Home Office therefore advises fresh checks and allows a 60-calendar-day grace period from the transfer in which to complete them. The grace period does not extend the deadline for any subsequent follow-up check.

The employer should also establish whether follow-up checks are required for individuals with time-limited permission to work and whether existing records demonstrate compliance with the applicable requirements.

The continuation of a sponsor licence does not, by itself, establish that the employer has a statutory excuse against a civil penalty for illegal working.

Similarly, possession of a Certificate of Sponsorship does not replace a prescribed right to work check.

These matters should be addressed through a coordinated sponsor compliance and right to work review before and after completion.

 

10. Establishing the licensing position before completion

 

Employers should establish the sponsor licensing consequences of an ownership transaction before completion wherever possible.

The assessment should begin with the legal identity of the current sponsor and a clear description of the proposed change in ownership or control.

It should then determine whether the transaction affects direct ownership, indirect ownership, the immediate parent company, the ultimate parent company or the organisation employing sponsored workers.

The employer should identify the relevant Home Office provisions, establish whether a new sponsor licence application is required and confirm the applicable reporting and application deadlines.

Where sponsored workers are affected, the parties should establish the arrangements under which those employees will continue to be sponsored and whether any additional immigration action is required.

Where the transaction introduces new directors, controlling shareholders or sponsor key personnel, the employer should also consider any suitability and reporting requirements.

The outcome should be documented and incorporated into the transaction implementation plan.

For more complex transactions, this may require coordination between the corporate legal advisers, employment advisers, HR function and the individuals responsible for sponsor licence compliance.

Early planning can help employers avoid completing a transaction without understanding whether the organisation will continue to hold the necessary authority to sponsor overseas workers.

Section D: Reporting Changes in Ownership and Control to the Home Office

 

Licensed sponsors have an ongoing duty to notify the Home Office of specified changes in their organisation and circumstances. Changes in ownership, control and corporate structure can trigger these obligations, alongside separate requirements relating to sponsor key personnel, business operations and the employment of sponsored workers.

The reporting requirements are set out in the Home Office Workers and Temporary Workers sponsor guidance, including section C4, which addresses mergers, takeovers and other changes in a sponsor’s circumstances.

For relevant ownership and corporate changes covered by these provisions, the guidance requires notification within no more than 20 working days. Certain transactions also require a new sponsor licence application within 20 working days.

These are distinct obligations. Reporting an ownership change does not automatically preserve an existing licence or remove the requirement for a new application. Equally, submitting a new licence application does not necessarily discharge every reporting duty arising from the transaction.

Employers should establish the precise nature of the change, the date on which it occurs, the relevant Home Office requirements and the organisation responsible for taking action.

Where a transaction involves several licensed sponsors or a transfer of sponsored workers between legal entities, the parties may have separate obligations. These should be identified before completion and incorporated into the transaction implementation plan.

 

1. Which ownership and control changes must be reported?

 

The Home Office requires licensed sponsors to report specified changes in their circumstances, including relevant changes in ownership and corporate structure.

Potentially reportable circumstances include changes in direct ownership, changes in ultimate or indirect ownership, mergers, takeovers, business transfers and certain reorganisations affecting the licensed organisation.

Changes to the organisation’s legal identity, trading arrangements, business addresses or sponsor key personnel may also engage separate reporting requirements.

Employers should not assume that every corporate change falls within the same reporting category or has the same licensing consequences.

Direct ownership changes

A change in direct ownership may involve the transfer of controlling shares in the licensed organisation or the introduction of a new immediate holding company.

The Home Office guidance provides examples in which these changes require notification and a new sponsor licence application within the applicable 20-working-day period.

For example, where a company transfers its controlling shares to a new individual but continues trading unchanged, the guidance requires the company to report the change and apply for a new licence.

The continuation of the same incorporated company does not remove these requirements.

Indirect ownership changes

A change in indirect ownership may occur where the sponsor’s immediate parent company remains unchanged but its ultimate parent changes following an acquisition further up the corporate group.

The Home Office guidance recognises that some indirect ownership changes may require reporting without necessarily requiring a new sponsor licence, provided the relevant circumstances and conditions are satisfied.

Employers should nevertheless assess the full corporate structure and determine whether the transaction changes direct ownership, indirect control or both.

Business transfers and changes of employing entity

Where a transaction involves sponsored workers transferring to another legal employer, the parties must assess the reporting requirements applicable to the transferring and receiving organisations.

The receiving organisation may also need to obtain a sponsor licence or extend an existing licence to cover the relevant sponsorship route.

The Home Office guidance contains specific requirements for qualifying transfers, including those involving TUPE or similar protection.

Changes in directors and key personnel

An acquisition may result in the appointment of new directors, the departure of existing management personnel or changes to the individuals responsible for sponsor compliance.

These changes should be assessed separately from the ownership transaction.

Where an Authorising Officer, Key Contact or Level 1 User changes, the sponsor must comply with the applicable procedures for updating its sponsor licence records.

A single acquisition may therefore require several distinct notifications and, depending on the transaction, a new licence application.

 

2. The 20-working-day reporting deadline

 

Section C4 of the Home Office sponsor guidance specifies that relevant changes covered by its provisions must be reported within no more than 20 working days.

The reporting period should be calculated by reference to the event that triggers the obligation under the applicable guidance.

Employers should identify the relevant transaction date rather than assuming that the deadline begins when the HR department becomes aware of the change or when the company’s next statutory filing is completed.

In a corporate acquisition, the relevant event may be the completion of the transaction or another event specified by the applicable Home Office provisions.

Where signing and completion occur on different dates, the employer should establish which event triggers the reporting requirement.

Similarly, where a transaction is implemented in several stages, each stage should be assessed to determine whether it creates a separate reportable change.

The reporting deadline should be recorded in a transaction compliance schedule and allocated to an individual with responsibility for ensuring that the notification is submitted.

Employers should avoid leaving the notification until the end of the permitted period, particularly where the transaction involves complex ownership structures or supporting evidence that may take time to obtain.

A late notification may constitute a breach of sponsor duties and can expose the organisation to Home Office scrutiny or other compliance action.

Where the transaction also requires a new sponsor licence application, employers must separately establish and comply with the applicable application deadline.

 

3. The 20-working-day requirement for new sponsor licence applications

 

Certain changes in ownership or corporate circumstances require an organisation to apply for a new sponsor licence within 20 working days.

This requirement is particularly important where the transaction constitutes a relevant change in direct ownership or where a receiving organisation needs a sponsor licence following a qualifying business transfer.

The Home Office guidance provides an example of a company transferring its controlling shares to a new owner while continuing to operate as before. In that scenario, the company must report the ownership change and apply for a new sponsor licence within 20 working days.

Where sponsored workers transfer to another organisation under the relevant business transfer provisions, the receiving organisation may also be required to apply for a sponsor licence or an extension to an existing licence within the prescribed period.

The application requirement should not be confused with the reporting obligation.

An SMS notification does not constitute a new sponsor licence application, and a new licence application does not necessarily satisfy every notification requirement arising from the transaction.

Employers should establish:

 

1. The applicant: which organisation is required to apply for the licence.
2. The triggering event: which ownership or employment change creates the application requirement.
3. The deadline: when the applicable 20-working-day period begins and expires.
4. The licence routes: which sponsorship routes the organisation requires.
5. The supporting evidence: which documents are required for the application.
6. The sponsor key personnel: who will hold the relevant compliance and SMS roles.
7. The sponsored workforce: which workers depend on the new or replacement licensing arrangements.
8. The interim position: what sponsorship activity is permitted while the application is being considered.

 

Submitting an application within the required period does not guarantee that the Home Office will grant the licence.

The applicant must satisfy the relevant eligibility and suitability requirements and may be subject to further enquiries or compliance checks.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

Employers should therefore incorporate the application requirement into the transaction timetable rather than treating it as an administrative task that can be completed at any convenient point after completion.

 

4. Who is responsible for reporting the change?

 

Responsibility for complying with sponsor duties rests with the licensed sponsoring organisation.

The Authorising Officer has overall responsibility for the organisation’s sponsorship arrangements, while authorised SMS users perform the functions permitted by their assigned roles.

Corporate transactions can complicate these responsibilities, particularly where the individuals previously responsible for sponsor compliance leave the business at completion.

For example, an acquisition may involve the departure of a director who also acts as Authorising Officer. The buyer may appoint new management personnel or reorganise the HR function responsible for immigration compliance.

The employer must ensure that appropriate individuals remain responsible for sponsor duties and that required notifications can be submitted through the relevant Home Office procedures.

Where both the seller and purchaser hold sponsor licences, the parties should identify their respective reporting responsibilities.

The seller’s notification should not automatically be treated as satisfying the buyer’s obligations, or vice versa.

Where sponsored workers transfer between organisations, both the transferring and receiving sponsors may need to take action under the applicable guidance.

Employers should document:

 

• Which organisation is responsible for each required notification.
• Who will prepare and submit the relevant information.
• Who has the necessary SMS permissions.
• Whether any sponsor key personnel changes must be completed.
• Who will respond to subsequent Home Office enquiries.
• Who will retain the evidence of compliance.

 

These responsibilities should be agreed before completion, particularly where access to corporate records or the Sponsor Management System may change following the transaction.

 

5. Reporting changes through the Sponsor Management System

 

The Sponsor Management System is the Home Office’s online platform for managing specified sponsor licence functions, including reporting relevant changes in sponsor circumstances.

Licensed sponsors should use the appropriate SMS procedures to notify the Home Office of reportable changes, subject to the requirements applicable to the particular event.

The information required will depend on the nature of the transaction.

For an ownership change, the sponsor may need to explain the corporate arrangements before and after completion, identify the relevant parties and provide details of the change.

Where the transaction involves a business transfer or a change in employing entity, additional information concerning the organisations and sponsored workers may be required.

Employers should ensure that the notification accurately reflects the legal structure of the transaction.

A general statement that the company has been acquired may be insufficient to explain whether the transaction involves a direct ownership change, an indirect ownership change or the transfer of employees to another legal entity.

The sponsor should also establish whether the relevant Home Office procedure requires supporting documents, a separate licence application or additional correspondence.

Submitting an SMS notification does not automatically confirm that the existing sponsor licence will continue or that every obligation arising from the transaction has been satisfied.

The employer should retain evidence of the notification and monitor any subsequent Home Office communication.

 

6. Supporting documents and transaction evidence

 

The Home Office may require supporting evidence to establish the nature of an ownership or control change and its implications for the licensed sponsor.

The documents required will depend on the transaction, the relevant reporting procedure and any additional information requested by the Home Office.

Potentially relevant evidence includes:

 

• Share purchase agreements or other transaction documents.
• Corporate structure charts showing ownership before and after completion.
• Companies House filings and confirmation statements.
• Records identifying shareholders and persons exercising significant control.
• Board resolutions and director appointment records.
• Documents confirming the continued existence or changed identity of the sponsoring legal entity.
• Business transfer agreements and restructuring documents.
• Employment records identifying the legal employer of sponsored workers.
• Details of any workers transferring between organisations.
• Information concerning changes to sponsor key personnel.
• Evidence of the receiving organisation’s sponsor licence, where relevant.
• Records of the immigration compliance assessment undertaken before completion.

 

Not every transaction will require all these documents.

However, the employer should be able to demonstrate what changed, when the change occurred and how the transaction affects the organisation holding the sponsor licence.

Where a transaction involves several corporate entities, clear structure charts can be particularly valuable.

The employer should distinguish between documents required for an SMS notification and those required for a new sponsor licence application.

These processes may have different evidential requirements and submission procedures.

 

7. The five-working-day supporting evidence requirement

 

In addition to the deadlines for reporting relevant changes, the Home Office sponsor guidance contains requirements concerning the submission of supporting documents following certain SMS change requests.

For an ownership-change request made through the relevant SMS function, the sponsor must complete and send the submission sheet, together with any required supporting evidence, within 5 working days.

Employers should establish whether this requirement applies to the particular change being reported and follow the submission instructions provided by the Home Office.

The five-working-day document submission period should not be confused with the 20-working-day period applicable to relevant ownership-change notifications.

They concern different stages of the compliance process.

For example, an employer may be required to report a relevant ownership change within 20 working days and then provide supporting evidence in accordance with the separate document submission requirements applicable to the SMS request.

Failure to supply required evidence within the prescribed period can affect the processing of the request and may create further compliance difficulties.

Employers should therefore prepare relevant documents before submitting a change request wherever possible.

Where supporting evidence is held by the seller, purchaser or external transaction advisers, arrangements for obtaining that evidence should be agreed before completion.

 

8. What happens after an ownership change is reported?

 

Submitting a notification does not necessarily conclude the sponsor licensing process.

The Home Office may consider the information provided, request further evidence or determine whether the transaction affects the organisation’s continuing entitlement to hold a sponsor licence.

Where the transaction requires a new sponsor licence application, the organisation must complete the relevant application process and satisfy the applicable requirements.

The Home Office may examine the organisation’s ownership, management arrangements, business operations and ability to comply with sponsor duties.

It may also consider whether the change affects the immigration position of sponsored workers.

Depending on the transaction and the applicable guidance, the existing licence may continue, be made dormant or be subject to revocation or other action.

These outcomes should be distinguished from compliance sanctions imposed because of misconduct or breaches of sponsor duties.

For example, a licence may be affected because the ownership transaction changes the licensing arrangements, rather than because the organisation has failed to comply with its obligations.

However, failure to report a relevant change or make a required application can create separate compliance concerns.

Employers should monitor the progress of any notification or application and respond promptly to Home Office requests.

They should not treat confirmation that an SMS request has been submitted as confirmation that the licensing consequences of the transaction have been resolved.

 

9. Consequences of failing to report a change

 

Failure to report a relevant ownership or control change within the applicable period can constitute a breach of sponsor duties.

The consequences depend on the nature of the omission, the requirements that applied and the wider circumstances of the organisation.

Where the transaction also required a new sponsor licence application, failure to make that application may have consequences beyond the reporting breach itself.

The Home Office may consider whether the organisation continues to hold the necessary sponsorship authorisation and whether the immigration position of affected workers remains secure.

Where C4.13 applies, if the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

Employers should not assume that a late notification automatically remedies a failure to make a required licence application.

Similarly, submitting a new application after the relevant deadline does not necessarily remove the consequences of missing that deadline.

Where a transaction has already completed and the employer discovers that a required change was not reported, the organisation should promptly establish:

 

1. What change occurred and when it took effect.
2. Which reporting obligations applied.
3. Whether a new sponsor licence application was required.
4. Whether the applicable deadlines have expired.
5. Which sponsored workers may be affected.
6. Whether any further sponsorship activity is permitted.
7. What corrective action is available under the applicable Home Office requirements.

 

The employer should obtain appropriate advice rather than assuming that the issue can be resolved by retrospectively updating the SMS record.

 

10. Post-completion reporting and compliance controls

 

Ownership and control transactions can create further reporting obligations after the initial acquisition has completed.

For example, the purchaser may subsequently reorganise the business, replace sponsor key personnel, transfer employees between group companies or change the locations from which sponsored workers perform their duties.

These developments should be assessed separately to determine whether additional notifications or licensing action are required.

Employers should maintain a post-completion compliance schedule covering:

 

• Confirmation that all ownership-related notifications have been submitted.
• Progress of any required new sponsor licence application.
• Submission of supporting documents within the applicable periods.
• Updates to sponsor key personnel and SMS permissions.
• Confirmation of the legal employing entity for each sponsored worker.
• Any required reporting concerning changes in sponsored employment.
• Reconciliation of sponsor records with current corporate information.
• Review of right to work checking responsibilities and records.
• Retention of transaction documents and Home Office correspondence.
• Monitoring of further changes arising during business integration.

 

The right to work review should reflect the expanded prescribed checking framework effective from 1 October 2026, including relevant worker contracts and individual subcontractor arrangements.

The employer should establish which organisation is responsible for the applicable checks and whether existing records support the statutory excuse requirements.

A change in ownership does not automatically require fresh right to work checks for every individual, but changes in employing entity and working arrangements may require further assessment.

These obligations should be managed alongside, but separately from, sponsor licence reporting.

A documented post-completion review helps employers demonstrate that they have addressed both the immediate ownership transaction and the subsequent changes affecting sponsorship and workforce compliance.

Section E: What Happens to Sponsored Workers After an Ownership Change?

 

The immigration position of sponsored workers is one of the most important considerations when a business changes ownership or control. A corporate transaction may leave employees working for the same legal entity, result in their employment transferring to another organisation or affect the sponsor licence under which their immigration permission was granted.

These circumstances can have different consequences under the Home Office sponsor guidance. Employers must establish whether the existing sponsor licence can continue, whether a new licence application is required and whether the workers can remain sponsored without making new immigration applications.

The relevant provisions are set out in section C4 of the Home Office Workers and Temporary Workers sponsor guidance, which addresses mergers, takeovers, changes of ownership and business transfers.

The guidance includes specific arrangements for sponsored workers whose employment transfers under TUPE or similar protection. Where the applicable conditions are satisfied, these workers may be able to continue their employment without obtaining new immigration permission or a new Certificate of Sponsorship.

However, these protections are not unconditional. The receiving organisation must satisfy the relevant sponsorship requirements, including holding or obtaining the appropriate sponsor licence and accepting responsibility for the workers.

Employers must also consider their separate right to work obligations. Changes effective from 1 October 2026 expanded the prescribed checking framework to specified worker contracts and individual subcontractor arrangements. The identity of the employer, the nature of the working arrangement and the applicable statutory excuse requirements must therefore be considered alongside sponsorship continuity.

 

1. Where employment remains with the same sponsor

 

In a conventional share acquisition, sponsored workers may continue to be employed by the same company after completion.

The company may retain its legal identity, trading name, business premises and existing employment contracts. The workers may continue performing the same duties under the same terms and conditions.

However, the continuation of the employment relationship does not automatically establish that the existing sponsor licence remains unaffected.

Under the Home Office sponsor guidance, certain changes in direct ownership can require a new sponsor licence application even where the sponsoring company continues to exist and employ the same workforce.

For example, Company A holds a Skilled Worker sponsor licence and employs several sponsored workers. A purchaser acquires the controlling shares in Company A.

Company A remains the legal employer following completion, and the workers continue in their existing roles.

Nevertheless, the ownership transaction may trigger the specific Home Office requirements concerning direct ownership changes, including notification and a new sponsor licence application within the applicable 20-working-day period.

The employer should establish:

 

• Whether the ownership change affects the status of the existing sponsor licence.
• Whether a new sponsor licence application is required.
• Which reporting and application deadlines apply.
• Whether the organisation remains authorised to sponsor the affected workers.
• Whether any changes to employment circumstances require separate reporting.
• Whether sponsor key personnel and compliance arrangements remain appropriate.
• Whether the existing right to work records remain sufficient under the applicable requirements.

 

Where the workers remain employed by the same legal entity, the share transaction does not necessarily involve a transfer of employment. However, the employer must still address any sponsor licensing consequences arising from the change in ownership or control.

The continued existence of the company should not be treated as a substitute for confirming the Home Office licensing position.

 

2. Where sponsored workers transfer to another employing entity

 

A different position arises where sponsored workers move from one legal employer to another as part of a business transaction.

This can occur through an asset acquisition, merger, transfer of undertaking, outsourcing arrangement or intra-group restructuring.

For example, Company A operates a business employing sponsored Skilled Workers. Company B acquires the business and becomes responsible for employing those workers.

Although the workers may continue performing the same duties at the same premises, their legal employer has changed.

Company B cannot automatically rely on Company A’s sponsor licence simply because it has acquired the business.

The parties must establish whether Company B already holds the appropriate sponsor licence or needs to obtain one under the Home Office provisions governing business transfers.

Where the transaction involves a qualifying transfer under TUPE or similar protection, the Home Office guidance provides arrangements under which existing sponsored workers may be able to continue without making new immigration applications.

However, the receiving organisation must satisfy the applicable conditions and accept responsibility for sponsorship.

Employers should distinguish between the transfer of the business, the transfer of employment and the transfer of sponsorship responsibility.

These matters are connected, but they are not legally interchangeable.

In particular, the fact that employment transfers under TUPE does not mean that the receiving organisation automatically acquires the seller’s sponsor licence.

 

3. TUPE and similar transfers: when new visas may not be required

 

The Home Office sponsor guidance contains specific provisions for sponsored workers whose employment transfers under TUPE or similar protection.

Where the relevant conditions are met, the workers may be able to continue working for the receiving organisation without obtaining new immigration permission or a new Certificate of Sponsorship solely because of the transfer.

This is an important protection for employers acquiring businesses with sponsored workforces.

Without these arrangements, a change in employing organisation could otherwise create significant immigration administration and uncertainty for affected employees.

The availability of the protection depends on the circumstances of the transfer and compliance with the relevant Home Office requirements.

In particular, employers should establish whether:

 

1. The transfer qualifies: the workers are covered by TUPE or similar protection recognised under the applicable sponsor guidance.
2. The receiving organisation is appropriately licensed: it holds the relevant sponsor licence or obtains the necessary licence within the prescribed period.
3. Sponsorship responsibility is accepted: the receiving organisation assumes responsibility for the affected sponsored workers.
4. The employment remains within the permitted arrangements: the workers continue in the same sponsored occupation code, with no material change taking the role outside the existing sponsored employment.
5. Reporting obligations are met: the transferring and receiving organisations complete the required Home Office notifications.
6. Records are maintained: the receiving organisation retains the relevant sponsorship and employment records.

 

Where these conditions are satisfied, the workers may not need to submit new visa applications or obtain replacement Certificates of Sponsorship solely because their employment has transferred.

Employers should not assume that every business transfer qualifies for this treatment.

For example, where a worker moves voluntarily to a different group company outside the relevant protected transfer provisions, the ordinary immigration rules concerning changes of sponsor may apply.

Similarly, where the worker’s duties or other material employment circumstances change, the employer must assess whether the transfer protections remain applicable or whether additional immigration action is required.

The position should be established for each affected worker before the transfer is implemented.

 

4. Receiving sponsor licence requirements and the 20-working-day deadline

 

Where sponsored workers transfer to another organisation, the receiving employer must establish whether it holds the appropriate sponsor licence.

If the receiving organisation already has a licence covering the relevant immigration route, it must still comply with the applicable requirements for accepting sponsorship responsibility and reporting the transfer.

Where the receiving organisation does not hold the necessary licence, the Home Office guidance provides a specific application requirement for qualifying business transfers.

In relevant circumstances, the receiving organisation must apply for the required sponsor licence within 20 working days.

An organisation that already holds a sponsor licence but needs authorisation under an additional sponsorship route may instead need to apply for the appropriate extension to its existing licence.

Employers should establish the correct application requirement rather than assuming that an existing licence for another route is sufficient.

The 20-working-day requirement is particularly important because failure to make a valid application within the prescribed period can have consequences for the affected sponsored workers.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

The receiving employer should therefore establish:

 

• Whether it already holds a sponsor licence.
• Whether that licence covers the immigration routes of the transferring workers.
• Whether a new licence application or extension is required.
• When the relevant 20-working-day period begins.
• Which supporting documents are required.
• Who will act as sponsor key personnel.
• How sponsorship responsibility will be managed while the application is considered.
• What action is required if the Home Office requests additional information.

 

Where the transaction is being planned in advance, the licensing requirements should be incorporated into the completion timetable.

The employer should not assume that a new application can be deferred indefinitely because the transferred employees already hold immigration permission.

 

5. Certificates of Sponsorship and immigration permission

 

A Certificate of Sponsorship is an electronic record assigned by an authorised sponsor to support an individual’s application under a relevant sponsored immigration route.

The worker’s immigration permission is granted by reference to the applicable immigration rules and sponsorship arrangements.

Where ownership or control changes, employers must establish whether the existing sponsorship arrangements remain valid and whether the transaction requires additional action.

The position depends on whether the worker remains employed by the same organisation, transfers under qualifying business transfer provisions or moves to another employer outside those provisions.

Workers remaining with the same legal employer

Where a share acquisition leaves the employing entity unchanged, the employer must assess the consequences of the ownership change for its sponsor licence.

The fact that employment continues does not remove any requirement for a new sponsor licence arising under the relevant direct ownership provisions.

Workers transferring under TUPE or similar protection

Where the relevant Home Office conditions are satisfied, workers may be able to continue without a new Certificate of Sponsorship or immigration application solely because of the transfer.

The receiving organisation must meet the applicable sponsor licensing, responsibility and reporting requirements.

Workers moving outside qualifying transfer arrangements

Where the transfer does not fall within the relevant provisions, the worker may need to meet the ordinary immigration requirements for changing sponsor.

Depending on the immigration route and circumstances, this may require a new Certificate of Sponsorship and an application for updated immigration permission.

Workers whose duties or employment circumstances change

A corporate transaction may also involve changes in occupation, duties, salary, work location or other relevant employment circumstances.

These changes should be assessed separately to establish whether reporting or a new immigration application is required.

Employers should not assume that the business transfer provisions permit every subsequent change in sponsored employment without further action.

 

6. Sponsored-worker due diligence before completion

 

Where a business employs sponsored workers, immigration due diligence should form part of the transaction assessment.

The buyer should establish which workers are sponsored, which legal entities currently employ them and how their employment will be structured following completion.

This is particularly important where only part of a business is being acquired or where employees will be allocated between several receiving organisations.

A worker-level immigration schedule should identify:

 

1. Employee identity: the individual whose immigration position is being assessed.
2. Current employer: the legal entity responsible for the existing employment relationship.
3. Current sponsor: the organisation holding the relevant sponsor licence.
4. Immigration route: the route under which the worker holds permission.
5. Permission expiry: the expiry date and any relevant pending application.
6. Certificate of Sponsorship: the existing sponsorship reference and relevant employment details.
7. Proposed employer: the legal entity expected to employ the worker after completion.
8. Transfer arrangements: whether the employment transfer falls within TUPE or similar protection.
9. Receiving sponsor licence: whether the proposed employer holds the necessary authorisation.
10. Required immigration action: any reporting, licence application, Certificate of Sponsorship or visa requirements.
11. Right to work records: the checks held and any applicable follow-up obligations.
12. Responsible personnel: the individuals responsible for completing the required actions.

 

The schedule should be reviewed immediately before completion to identify any changes in the proposed employee allocation or transaction structure.

Where workers are transferring between several group companies, the sponsor licensing position of each receiving organisation should be considered separately.

The employer should also establish whether the proposed integration arrangements will change sponsored workers’ duties, work locations or reporting arrangements after completion.

 

7. Right to work checks following a change of ownership

 

Employers must distinguish between the continuation of immigration sponsorship and compliance with the prescribed right to work checking requirements.

A sponsor licence authorises an eligible organisation to sponsor workers under specified immigration routes. It does not, by itself, establish a statutory excuse against liability for illegal working.

The employer must comply with the right to work checking requirements applicable to the individual and the relevant working arrangement.

Changes effective from 1 October 2026 extended the prescribed checking framework to specified worker contracts and individual subcontractor arrangements, in addition to conventional employment relationships.

This means that acquisition due diligence should not focus exclusively on employees holding sponsored work visas.

The business should also identify other individuals whose working arrangements fall within the expanded right to work framework.

Share acquisitions

Where the company employing the workforce remains the same legal entity following a share acquisition, the change in ownership does not automatically mean that every employee must undergo a fresh right to work check.

The employer should nevertheless review the adequacy of existing checking arrangements, particularly where the acquisition identifies missing records, expired permission or failures to complete required follow-up checks.

Business transfers

On a qualifying TUPE transfer, the incoming employer obtains the benefit of any statutory excuse established by the outgoing employer, but can inherit exposure where the original check was defective. The Home Office therefore advises fresh checks and allows a 60-calendar-day grace period from the transfer in which to complete them. The grace period does not extend the deadline for any subsequent follow-up check.

Workers and individual subcontractors

Following the October 2026 changes, employers should identify relevant worker and individual subcontractor arrangements that fall within the expanded prescribed checking requirements.

The fact that an individual is not employed under a conventional contract of employment does not necessarily place the arrangement outside the applicable right to work framework.

Time-limited immigration permission

Where an individual’s right to work is time-limited, the employer must comply with the applicable follow-up checking requirements to maintain the relevant statutory excuse.

The transaction should not result in the loss of records or responsibility for monitoring permission expiry dates.

Right to work compliance should therefore be included in both pre-completion due diligence and post-completion integration planning.

 

8. Statutory excuse and sponsor licence compliance are separate obligations

 

The statutory excuse against liability for illegal working is a separate legal concept from sponsor licence authorisation.

A licensed sponsor may comply with certain sponsorship requirements but still face right to work compliance concerns if prescribed checks have not been carried out correctly.

Similarly, an employer may hold appropriate right to work records but still need to address the sponsor licensing consequences of a change in ownership or employing entity.

The two frameworks should therefore be assessed independently, even though they can affect one another.

Under the Home Office sponsor guidance, failures concerning right to work compliance can have consequences for sponsor suitability and the organisation’s ability to retain its licence.

Receiving a civil penalty for illegal working or failing to carry out required checks can expose a sponsor to serious compliance action, including licence revocation where the applicable grounds are met.

For businesses undergoing acquisitions, this creates an additional reason to examine workforce compliance before completion.

The buyer should establish whether the target business has appropriate right to work policies, records and monitoring arrangements, and whether any historical compliance issues may affect the sponsor licence.

Following completion, responsibility for right to work compliance should be clearly allocated within the organisation.

Where the business uses a combination of employees, workers, agency personnel and individual subcontractors, the employer should establish which arrangements fall within the applicable prescribed checking framework.

 

9. Protecting sponsorship continuity during the transaction

 

Employers should begin planning the immigration workstream before the transaction completes.

The first step is to identify the sponsored workforce and establish whether the workers will remain with the same legal employer or transfer to another organisation.

The parties should then determine whether the existing sponsor licence can continue, whether a new licence application is required and whether the relevant business transfer provisions apply.

Where the receiving organisation needs a sponsor licence or an extension to its existing licence, the applicable application deadline should be recorded and responsibility for the application allocated.

The parties should also identify any required Home Office notifications, the relevant supporting evidence and the individuals responsible for submitting the information.

Particular attention should be given to transactions involving:

 

• Several sponsoring companies within a corporate group.
• Transfers of only part of a business.
• Changes in the legal entity employing sponsored workers.
• Direct ownership changes requiring new sponsor licence applications.
• Sponsored workers whose immigration permission is approaching expiry.
• Changes to job duties, salaries or work locations.
• Departure of sponsor key personnel at completion.
• Existing sponsor compliance concerns or Home Office investigations.
• Right to work record deficiencies.
• Workers or individual subcontractors affected by the October 2026 right to work changes.

 

The objective is to establish a lawful and workable sponsorship position for the business after completion.

Where the relevant action cannot be completed immediately, the employer should obtain advice on the applicable Home Office provisions rather than assuming that commercial completion permits sponsorship to continue automatically.

 

10. Post-completion checks for sponsored workers

 

After completion, the employer should confirm that the immigration actions identified during the transaction have been completed.

This includes verifying the status of any required sponsor licence application, confirming that the appropriate organisation has accepted sponsorship responsibility and ensuring that relevant notifications have been submitted.

The employer should also reconcile its sponsored-worker records with the actual post-completion employment arrangements.

Where employees have transferred between legal entities, the organisation should confirm that the records identify the correct employer and sponsor.

Any changes in duties, salaries, work locations or other relevant employment circumstances should be assessed against the applicable sponsor reporting requirements.

Right to work records should also be reviewed to establish whether the organisation has the evidence required under the applicable statutory excuse provisions.

The post-completion review should address:

 

1. Confirmation of the legal employer of each sponsored worker.
2. Confirmation of the organisation responsible for sponsorship.
3. The status of any new sponsor licence application or extension.
4. Completion of required Home Office notifications.
5. Compliance with applicable reporting and application deadlines.
6. Any required changes to Certificates of Sponsorship or immigration permission.
7. Review of sponsored employment duties and conditions.
8. Confirmation of sponsor key personnel and SMS access.
9. Retention of immigration and employment records.
10. Review of right to work checks and follow-up requirements.
11. Identification of relevant worker and individual subcontractor arrangements.
12. Monitoring of further changes arising during business integration.

 

The employer should retain an auditable record of the assessment, decisions taken and actions completed.

A properly managed ownership change should leave the organisation with a clear understanding of its sponsor licence position, the immigration status of its sponsored workforce and its continuing responsibilities under the Home Office sponsorship and right to work frameworks.

Section F: Ownership and Control Changes That Create Sponsor Licence Risks

 

Changes in company ownership or control can expose a sponsoring organisation to significant immigration compliance risks. These risks are not limited to whether the Home Office has been notified of the transaction. An acquisition or reorganisation can affect the status of the sponsor licence, the organisation’s suitability to hold that licence, its management arrangements and the legal entity responsible for sponsored workers.

The risks can become particularly serious where a transaction completes before the parties have established whether the existing sponsor licence can continue or whether a new application is required.

Under the Home Office Workers and Temporary Workers sponsor guidance, certain changes in direct ownership require a new sponsor licence application within the applicable 20-working-day period. Relevant ownership and corporate changes must also be reported within the prescribed deadlines.

Failure to comply with these requirements can have consequences for the organisation’s ability to sponsor workers and, in relevant circumstances, the immigration permission of affected employees.

Corporate transactions can also reveal historical sponsor compliance weaknesses, including inaccurate records, unreported changes, unsuitable key personnel and deficiencies in right to work checking arrangements.

Following the changes effective from 1 October 2026, employers must also consider the expanded prescribed right to work checking framework covering specified worker contracts and individual subcontractor arrangements.

For these reasons, sponsor licence compliance should form a distinct workstream within transaction due diligence, completion planning and post-acquisition integration.

 

1. Failure to report a relevant ownership or control change

 

Licensed sponsors must report specified changes in their organisation and circumstances within the periods prescribed by Home Office guidance.

Section C4 of the Workers and Temporary Workers sponsor guidance requires relevant ownership and corporate changes to be reported within no more than 20 working days.

A failure to make the required notification can constitute a breach of sponsor duties.

Reporting failures can occur for several reasons. The corporate transaction team may not recognise the immigration implications of a share sale, the HR function may not be informed of the acquisition or responsibility for the notification may not be allocated before completion.

For example, an overseas parent company may acquire control of a UK business holding a sponsor licence without involving the UK employees responsible for managing sponsorship.

The UK company may continue trading under the same name and employing the same sponsored workers, but the ownership transaction may still engage the Home Office reporting requirements.

The employer must establish whether the change affects direct or indirect ownership and identify the relevant notification obligations.

Where the transaction also requires a new sponsor licence application, submitting an ownership notification does not remove that separate requirement.

Employers should therefore distinguish between:

 

• The obligation to report the relevant ownership or control change.
• The requirement to apply for a new sponsor licence where applicable.
• Separate notifications concerning directors, key personnel or corporate information.
• Reporting obligations arising from transfers of sponsored workers.
• Further notifications required during post-completion integration.

 

Late reporting should not be treated as a purely administrative oversight.

Depending on the circumstances, failure to comply with sponsor duties may expose the organisation to Home Office scrutiny, compliance action or consequences affecting its sponsor licence.

Where an employer discovers that a reportable change has not been notified, it should establish the nature of the omission, whether any application deadline has also been missed and what corrective action is available.

 

2. Failure to apply for a new sponsor licence following a direct ownership change

 

One of the most significant risks arises where the parties assume that an existing sponsor licence automatically continues following a share acquisition.

In a conventional share sale, the sponsoring company may remain the same incorporated legal entity. Its contracts, employees and trading operations may remain unchanged.

However, the Home Office sponsor guidance provides specific rules for changes in direct ownership.

The guidance includes an example of a company transferring its controlling shares to a new individual while continuing to trade as before. In that scenario, the company must report the change and apply for a new sponsor licence within 20 working days.

A similar issue can arise where a new immediate holding company is introduced into the corporate structure.

The parties should not assume that the absence of a change in legal entity or ultimate beneficial ownership means that the existing licence can continue without further action.

Failure to identify a required new licence application can create uncertainty about the organisation’s authority to sponsor workers.

It may also affect the immigration position of existing sponsored employees and the business’s ability to recruit additional overseas workers.

Employers should therefore assess the transaction structure before completion and determine whether the Home Office requires a new application.

Where an application is necessary, the organisation should establish the applicant, relevant sponsorship routes, supporting evidence, key personnel and applicable deadline.

Submitting a new licence application does not guarantee approval. The organisation must satisfy the relevant eligibility and suitability requirements.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

 

3. New owners, directors and sponsor suitability

 

The Home Office assesses whether an organisation is suitable to hold a sponsor licence.

Ownership and management changes may introduce individuals or corporate relationships relevant to that assessment.

An acquisition may result in new controlling shareholders, directors, senior managers or other individuals becoming involved in the sponsoring organisation.

The transaction may also change the people responsible for overseeing immigration compliance.

Employers should establish whether these developments engage any suitability requirements, restrictions or reporting obligations under the current sponsor guidance.

Particular attention may be required where a proposed owner, director or other relevant individual has previously been involved in sponsor compliance failures, immigration breaches or circumstances that could affect sponsor suitability.

The employer should not assume that the original grant of a sponsor licence permanently resolves suitability questions regardless of subsequent changes in ownership or management.

Equally, the appointment of a new director or shareholder should not automatically be characterised as a compliance breach.

The relevant facts must be assessed against the applicable Home Office requirements.

Where potential concerns are identified, the parties should investigate them before completion so that the immigration consequences can be considered alongside the wider commercial and legal risks of the transaction.

Appropriate due diligence may include reviewing previous sponsor licence decisions, compliance action, the background of relevant individuals and the arrangements through which the new owners will exercise control.

 

4. Inaccurate corporate information and sponsor records

 

A corporate transaction can leave the information held by the Home Office inconsistent with the organisation’s current structure.

Potential discrepancies may concern ownership, company addresses, trading arrangements, directors, sponsor key personnel or the legal identity of the organisation employing sponsored workers.

These problems are more likely where a business has undergone several acquisitions or internal reorganisations without a coordinated review of its sponsor records.

For example, a company may change its registered office, appoint new directors and reorganise its HR function following an acquisition.

Each change should be assessed against the relevant Home Office reporting requirements rather than assuming that a single ownership notification addresses every obligation.

Inaccurate or outdated records can complicate Home Office enquiries, compliance visits and subsequent sponsor licence applications.

Employers should therefore reconcile their corporate records with the information held under their sponsor licence.

The review should consider:

 

• The legal identity of the licensed sponsor.
• The company’s registered and trading addresses.
• Its direct and indirect ownership structure.
• Relevant directors and controlling individuals.
• The Authorising Officer, Key Contact and SMS users.
• The legal entities employing sponsored workers.
• Any changes in trading or operational arrangements.
• Outstanding reporting obligations.
• Previous Home Office correspondence or compliance action.

 

Where discrepancies are identified, the employer should determine the appropriate procedure for updating the information and retain evidence of the action taken.

The review should also establish whether any historical changes were not reported within the applicable deadlines.

 

5. Unplanned changes to the employing legal entity

 

One of the more serious transaction risks arises where the parties believe they are implementing a straightforward change in ownership but the arrangements also involve a change in the legal entity employing sponsored workers.

This can happen during asset acquisitions, group reorganisations, business integrations or transactions involving the movement of employees between companies.

The business may retain its trading name, premises, management team and commercial operations while responsibility for employment moves to a different legal entity.

For sponsor licensing purposes, the identity of the employing organisation is important.

A sponsor licence cannot simply be transferred to another company as part of a commercial transaction.

Where sponsored workers move to a receiving employer, the parties must establish whether that organisation holds the appropriate sponsor licence or needs to obtain one.

The Home Office guidance contains provisions addressing qualifying business transfers, including those involving TUPE or similar protection.

Where the relevant conditions are satisfied, sponsored workers may be able to continue without obtaining new immigration permission or a new Certificate of Sponsorship solely because of the transfer.

However, the receiving organisation must satisfy the applicable licensing and reporting requirements and accept responsibility for sponsorship.

Where a new licence or extension is required, the Home Office guidance provides a 20-working-day application requirement in relevant circumstances.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

Employers should therefore verify the legal identity of the employer before and after completion rather than relying on the commercial description of the transaction.

 

6. Sponsor key personnel and management continuity

 

Corporate transactions can disrupt the management arrangements through which an organisation meets its sponsor duties.

An acquisition may result in the departure of directors, HR managers or other employees who previously held responsibility for immigration compliance.

Where these individuals also act as sponsor key personnel, the transaction may create additional reporting and operational requirements.

The Authorising Officer has overall responsibility for the organisation’s sponsorship arrangements, while authorised SMS users perform functions within their assigned permissions.

Employers should ensure that appropriate individuals remain in place to oversee sponsor compliance and manage the Sponsor Management System.

For example, if the existing Authorising Officer leaves the business at completion, the organisation should establish the requirements for appointing a replacement and updating its sponsor records.

Similarly, where Level 1 Users leave the organisation, their SMS access should be reviewed and appropriate replacement arrangements made.

Failure to maintain effective sponsor management arrangements can create compliance problems even where the ownership transaction itself has been correctly reported.

Employers should therefore incorporate sponsor key personnel changes into the completion and post-completion implementation plan.

Responsibility for reporting, record keeping, sponsored-worker monitoring and Home Office correspondence should be clearly allocated.

 

7. Right to work compliance risks following the 1 October 2026 changes

 

Ownership and control transactions can also expose deficiencies in right to work compliance.

Employers must distinguish between their obligations as licensed sponsors and their separate responsibilities under the illegal working prevention framework.

A sponsor licence does not automatically establish a statutory excuse against liability for illegal working. The employer must comply with the prescribed right to work checking requirements applicable to the relevant individual and working arrangement.

Changes effective from 1 October 2026 extended the prescribed checking framework to specified worker contracts and individual subcontractor arrangements, in addition to conventional employment relationships.

This increases the importance of examining the wider workforce during acquisition due diligence.

A buyer should not limit its assessment to employees holding sponsored visas or assume that all individuals outside conventional employment contracts fall outside the prescribed checking requirements.

The review should identify:

 

• Employees subject to prescribed right to work checks.
• Workers whose contractual arrangements fall within the expanded framework.
• Relevant individual subcontractors.
• Individuals with time-limited immigration permission.
• Existing right to work records and evidence of prescribed checks.
• Outstanding follow-up checking obligations.
• Any historical illegal working concerns or civil penalties.
• The organisation responsible for compliance following completion.

 

Where a share acquisition leaves the employing legal entity unchanged, the ownership change does not automatically require every employee to undergo a fresh right to work check.

However, the employer should assess whether existing records are sufficient and whether any compliance deficiencies require attention.

On a qualifying TUPE transfer, the incoming employer obtains the benefit of any statutory excuse established by the outgoing employer, but can inherit exposure where the original check was defective. The Home Office therefore advises fresh checks and allows a 60-calendar-day grace period from the transfer in which to complete them. The grace period does not extend the deadline for any subsequent follow-up check.

Failures concerning right to work compliance can also affect sponsor suitability.

Under the Home Office sponsor guidance, failure to carry out required right to work checks or receiving a civil penalty for illegal working can expose an organisation to serious sponsor licence consequences, including revocation where the applicable grounds are met.

Right to work due diligence should therefore be treated as an integral part of the wider workforce compliance assessment accompanying a corporate transaction.

 

8. Sponsor licence suspension, revocation and other Home Office action

 

Failure to comply with sponsor duties can result in Home Office compliance action, depending on the nature and seriousness of the breach.

Possible consequences include further enquiries, compliance visits, licence downgrading, suspension or revocation where the relevant grounds are met.

Ownership and control transactions can also engage specific Home Office provisions affecting the status of an existing licence.

These matters should be distinguished.

A sponsor licence may be affected because a change in ownership or corporate structure requires a new licensing arrangement. That outcome should not automatically be described as a sanction for misconduct.

By contrast, where the employer fails to report relevant changes, does not make a required application or breaches other sponsor duties, the Home Office may consider compliance action under the applicable provisions.

Employers should distinguish between:

 

1. Transaction-related licensing consequences: changes to licence status arising from ownership, control or corporate restructuring.
2. New licence requirements: the obligation to obtain appropriate sponsorship authorisation following a relevant transaction.
3. Reporting failures: breaches arising from failure to notify the Home Office within the prescribed period.
4. Sponsor suitability concerns: issues involving the organisation, its management or other relevant individuals.
5. Sponsored-worker consequences: risks to the immigration permission of employees whose sponsorship arrangements are affected.
6. Right to work breaches: failures under the illegal working prevention framework that may also affect sponsor compliance.

 

The Home Office’s response will depend on the applicable guidance and the circumstances of the organisation.

Employers should not assume that every ownership change results in suspension or revocation. Equally, they should not assume that a licence remains unaffected merely because the business continues trading.

Where a transaction has already completed without appropriate sponsor licence planning, the employer should establish its current licensing position promptly and identify any outstanding obligations.

 

9. Immigration risks identified during acquisition due diligence

 

For a purchaser acquiring a business that holds a sponsor licence, immigration due diligence can identify risks that may affect the value, operation or integration of the target business.

The review should establish the status of the sponsor licence, the sponsored workforce, the organisation’s compliance history and the consequences of the proposed transaction.

Potential findings may include:

 

• Unreported changes in ownership or corporate circumstances.
• Previous sponsor licence suspension, downgrading or compliance action.
• Outstanding Home Office enquiries or investigations.
• Inaccurate sponsor records or missing supporting documents.
• Deficiencies in sponsor key personnel arrangements.
• Sponsored workers employed by entities different from those recorded in the relevant sponsorship arrangements.
• Unreported changes to sponsored employment.
• Missing or inadequate right to work records.
• Failures to undertake required follow-up checks.
• Relevant worker or individual subcontractor arrangements requiring assessment under the October 2026 framework.
• Potential sponsor suitability concerns involving incoming owners or managers.
• A requirement for a new sponsor licence following completion.

 

The findings should inform the transaction structure and the actions required before and after completion.

Where material compliance concerns are identified, the parties may need to consider how those risks are addressed within the transaction documentation and implementation arrangements.

However, contractual warranties or indemnities cannot replace compliance with Home Office sponsor licensing requirements.

The acquiring organisation must establish that the post-transaction business has the necessary authority and systems to sponsor workers lawfully.

 

10. Managing ownership and control risks before completion

 

The most effective way to manage sponsor licence risks is to identify them before the transaction completes.

The employer should begin with a clear understanding of the existing corporate structure, the proposed ownership changes and the legal entities responsible for sponsored workers.

The assessment should then determine whether the transaction engages the Home Office provisions concerning direct ownership, indirect ownership, business transfers or changes in employing entity.

Where a new sponsor licence application is required, the relevant 20-working-day deadline should be identified and incorporated into the transaction timetable.

The employer should also establish the reporting requirements, supporting evidence, sponsor key personnel arrangements and immigration position of affected workers.

Right to work compliance should be reviewed separately, including the expanded checking framework effective from 1 October 2026.

The outcome should be a documented immigration compliance plan identifying:

 

1. The sponsor licences affected by the transaction.
2. The legal entities responsible for sponsorship before and after completion.
3. Any requirement for a new sponsor licence application.
4. The applicable reporting and application deadlines.
5. The sponsored workers affected by the transaction.
6. Any required immigration applications or sponsorship changes.
7. Changes to sponsor key personnel and SMS permissions.
8. Relevant sponsor suitability issues.
9. Right to work checking and record-keeping responsibilities.
10. The individuals responsible for completing each action.
11. The evidence required to demonstrate compliance.
12. The post-completion monitoring and review arrangements.

 

Where several corporate entities are involved, the parties should coordinate their responsibilities to ensure that reporting and licensing obligations are not overlooked.

Employers should also revisit the assessment immediately before completion, particularly where the transaction structure has changed since the initial review.

A properly documented approach can help reduce the risk of missed deadlines, uncertainty over sponsorship responsibility and disruption to the business’s ability to employ sponsored workers.

Section G: How Employers Should Manage a Proposed Change of Control

 

Employers planning a change in ownership or control should address the sponsor licensing consequences before the transaction completes. The objective is to establish whether the existing licence can continue, whether a new sponsor licence application is required and how the organisation will maintain compliance with its obligations to the Home Office.

Corporate transactions can involve several legal entities, different ownership structures and changes to the workforce. The immigration consequences are not always apparent from the commercial description of the transaction.

A share acquisition may leave the sponsoring company and its employees unchanged while still triggering a new licence requirement under the Home Office rules on direct ownership. An internal group restructuring may alter the sponsor’s immediate parent company even where ultimate ownership remains unchanged. A business or asset sale may result in sponsored workers transferring to another legal employer.

Employers should therefore treat immigration compliance as a separate workstream within transaction planning, alongside corporate, employment, tax and regulatory due diligence.

The assessment should begin before completion, continue through the transaction and conclude with a documented post-completion review.

 

1. Before completion: sponsor licence and immigration due diligence

 

The pre-completion stage provides the best opportunity to identify sponsor licensing risks and determine whether changes to the transaction timetable or implementation arrangements are required.

The employer should begin by establishing the legal identity of every organisation holding a sponsor licence and the immigration routes covered by each licence.

Where the target business operates through several subsidiaries, the parties should not assume that a licence held by one company authorises all other group companies to sponsor workers.

The due diligence should establish which entities employ sponsored workers, whether those employees will remain with their existing employer and whether any transfers are proposed.

Review the ownership structure

The parties should prepare corporate structure charts showing the position before and after the proposed transaction.

These should identify the licensed sponsor, its immediate shareholders or parent company, its ultimate parent and any intermediate holding companies.

The assessment should distinguish between direct and indirect ownership changes.

Particular attention should be given to transactions involving controlling share transfers or the introduction of a new immediate holding company, as the Home Office guidance contains examples in which these changes require a new sponsor licence.

Where only the ultimate parent changes, the parties should establish whether the circumstances fall within the relevant Home Office provisions concerning indirect ownership changes.

Establish the existing sponsor licence position

The buyer should obtain sufficient information to assess the status of each relevant sponsor licence.

This should include the licence rating, sponsorship routes, key personnel arrangements, compliance history and any outstanding Home Office enquiries.

Where the organisation has previously experienced compliance action, the parties should establish whether the underlying issues have been resolved and whether they could affect the post-transaction licensing position.

Identify sponsored workers

A worker-level schedule should identify employees sponsored under the relevant immigration routes, their current legal employer, immigration permission expiry dates and proposed post-completion arrangements.

Where employees are expected to transfer between legal entities, the parties should assess whether the transaction qualifies for the relevant Home Office provisions concerning TUPE or similar protection.

They should also establish whether the receiving organisation holds the necessary sponsor licence or needs to apply for one.

Assess sponsor suitability

The employer should consider whether incoming owners, directors or other relevant individuals raise issues under the applicable Home Office sponsor suitability requirements.

Any concerns should be investigated before completion rather than being left to the post-acquisition integration process.

Review right to work compliance

The due diligence should examine the organisation’s right to work checking procedures, records and follow-up arrangements.

Following the changes effective from 1 October 2026, the assessment should also consider specified worker contracts and individual subcontractor arrangements within the expanded prescribed checking framework.

The review should identify missing records, unresolved immigration status concerns, previous illegal working issues and any civil penalties that may be relevant to sponsor suitability.

Determine the required Home Office action

Before completion, the parties should identify each required notification, sponsor licence application and sponsored-worker action.

For relevant ownership changes, the Home Office guidance provides a reporting period of no more than 20 working days.

Certain direct ownership changes and qualifying business transfers also engage a separate 20-working-day requirement for a new sponsor licence application or an extension to an existing licence.

These requirements should be incorporated into the transaction timetable and allocated to the appropriate organisation.

 

2. During the transaction: completion planning and responsibility

 

Once the immigration consequences have been identified, the parties should prepare an implementation plan that can be followed at completion.

This is particularly important where the transaction involves several sponsoring organisations, changes to the employing entity or the departure of existing sponsor key personnel.

The implementation plan should identify the relevant legal entities, the effective date of the transaction, the Home Office actions required and the individuals responsible for completing them.

Confirm the final transaction structure

Corporate transactions can change between initial agreement and completion.

For example, a proposed direct share acquisition may be restructured to involve a new holding company, or the buyer may decide that employees will transfer to another group entity.

These changes can materially affect the sponsor licensing assessment.

The immigration workstream should therefore review the final transaction structure before completion and confirm whether the original conclusions remain valid.

Identify the relevant completion date

The parties should establish the date on which the ownership or employment change takes effect for the purposes of the applicable Home Office requirements.

This is necessary to calculate reporting and application deadlines accurately.

Where signing and completion occur on different dates, the parties should identify the event that triggers each relevant obligation.

Where a transaction completes in stages, the employer should establish whether each stage creates a separate reportable change.

Allocate reporting responsibilities

The implementation plan should specify which organisation is responsible for each Home Office notification.

Where both the seller and purchaser hold sponsor licences, their respective obligations should be identified separately.

The parties should not assume that one organisation’s notification automatically satisfies the other’s requirements.

Prepare new sponsor licence applications

Where the transaction requires a new sponsor licence application, the employer should prepare the necessary information and supporting evidence in advance.

This may include corporate documents, ownership charts, evidence of trading activities, details of key personnel and information concerning sponsored workers.

The relevant 20-working-day application deadline should be recorded, and the organisation should establish the procedure for submitting the application.

Maintain sponsor management arrangements

The parties should ensure that appropriate sponsor key personnel remain available during and after completion.

Where the existing Authorising Officer or Level 1 Users are leaving the business, replacement arrangements should be planned in accordance with the Home Office requirements.

The employer should avoid a situation in which the transaction completes but no authorised individual is able to manage required SMS functions or respond to Home Office enquiries.

Protect sponsored-worker continuity

Where employees are transferring between legal entities, the receiving organisation should be prepared to accept sponsorship responsibility in accordance with the applicable Home Office provisions.

The parties should confirm which workers are transferring, the immigration routes involved and whether the conditions for continuing sponsorship without new immigration applications are satisfied.

Any material changes to employment duties or arrangements should be assessed separately.

 

3. After completion: reporting, licensing and workforce compliance

 

Completion of the commercial transaction does not conclude the organisation’s immigration responsibilities.

The employer must ensure that the required Home Office notifications and applications are completed within the applicable periods and that sponsorship arrangements reflect the post-transaction business structure.

Submit required ownership notifications

The organisation should report relevant ownership and corporate changes through the appropriate Home Office procedures.

Where section C4 applies, the relevant changes must be reported within no more than 20 working days.

The employer should retain evidence of submission and monitor any subsequent Home Office communication.

Complete required licence applications

Where the transaction requires a new sponsor licence application or an extension to an existing licence, the employer should ensure that the application is submitted within the applicable deadline.

The organisation should monitor the application and respond promptly to requests for further information.

Submission of an application should not be treated as confirmation that the licence has been granted or that every licensing issue has been resolved.

Provide supporting evidence

Where the Home Office requires documents in connection with an SMS change request, the employer should comply with the applicable submission instructions and deadlines.

Under the relevant Part 3 provisions, certain change requests engage a five-working-day period for submitting the declaration, submission sheet and supporting documents.

This is separate from the 20-working-day ownership reporting or new licence application requirements.

Update sponsor key personnel

The employer should confirm that the Authorising Officer, Key Contact and SMS users are appropriate for the post-transaction organisation.

Where individuals have left the business, their access and responsibilities should be reviewed and the required changes completed.

Reconcile sponsored-worker records

The employer should verify that each sponsored worker is employed by the organisation identified in the post-transaction sponsorship arrangements.

Where employees have transferred, the receiving organisation should confirm that it has accepted the relevant sponsorship responsibilities and completed the required notifications.

Changes to duties, salaries, work locations or other material employment circumstances should be assessed against the applicable reporting requirements.

Review right to work records

The employer should confirm that it holds the right to work evidence required under the applicable statutory excuse provisions.

The review should cover conventional employees and relevant worker or individual subcontractor arrangements within the framework effective from 1 October 2026.

Where a share acquisition leaves the legal employer unchanged, the ownership change does not automatically require fresh checks for every worker.

On a qualifying TUPE transfer, the incoming employer obtains the benefit of any statutory excuse established by the outgoing employer, but can inherit exposure where the original check was defective. The Home Office therefore advises fresh checks and allows a 60-calendar-day grace period from the transfer in which to complete them. The grace period does not extend the deadline for any subsequent follow-up check.

Outstanding follow-up checks should be identified and responsibility for monitoring them allocated.

Monitor further integration changes

Post-acquisition integration may involve further reorganisations, changes in employing entity, movement of sponsored workers or replacement of sponsor key personnel.

Each subsequent change should be assessed to determine whether additional Home Office action is required.

The original ownership notification should not be assumed to cover every later development.

 

4. Employer checklist: managing a change of ownership or control

 

The following checklist provides a practical framework for employers planning or implementing a transaction affecting a licensed sponsor.

It should be adapted to the structure of the transaction, the organisations involved and the applicable Home Office requirements.

Before completion

 

1. Identify the licensed sponsor: confirm the full legal identity of every organisation holding a relevant sponsor licence.
2. Map ownership: prepare pre-transaction and post-transaction corporate structure charts identifying direct and indirect ownership.
3. Assess the transaction: establish whether the change involves controlling shares, a new immediate holding company, an ultimate parent change or a transfer of business operations.
4. Determine licence consequences: identify whether the existing licence can continue or whether a new application is required under section C4.
5. Identify sponsored workers: prepare a schedule of affected employees, immigration routes, current employers and proposed post-completion arrangements.
6. Assess transfers: determine whether any movement of sponsored workers falls within TUPE or similar protection recognised by the Home Office guidance.
7. Review receiving entities: confirm whether each proposed receiving employer holds the appropriate sponsor licence or needs to apply for one.
8. Review sponsor suitability: assess relevant issues concerning incoming owners, directors, managers and the organisation’s compliance history.
9. Audit right to work compliance: review existing checks, records and follow-up arrangements, including relevant worker and individual subcontractor arrangements under the October 2026 framework.
10. Identify deadlines: record the applicable reporting, licence application and supporting evidence submission requirements.

 

At completion

 

11. Confirm the final structure: verify that the transaction has completed in the form assessed for sponsor licensing purposes.
12. Record the effective date: establish the event and date triggering each relevant Home Office obligation.
13. Allocate responsibilities: confirm which organisation and individual will complete each notification, application and sponsored-worker action.
14. Maintain operational control: ensure that appropriate sponsor key personnel and SMS access remain available.
15. Confirm worker arrangements: establish the legal employer and responsible sponsor for every affected sponsored worker.

 

After completion

 

16. Report ownership changes: submit the required notifications within the applicable 20-working-day period.
17. Submit licence applications: complete any required new sponsor licence application or extension within the prescribed deadline.
18. Provide supporting documents: for an ownership-change request made through the relevant SMS function, complete and send the submission sheet, together with any required supporting evidence, within 5 working days.
19. Complete sponsored-worker reporting: ensure that the transferring and receiving organisations satisfy their respective obligations.
20. Update sponsor records: reconcile ownership, management, addresses, key personnel and other relevant information.
21. Review right to work obligations: confirm that the responsible organisation holds appropriate records and has arrangements for follow-up checks.
22. Monitor Home Office decisions: track the progress of any application or enquiry and respond within the applicable deadlines.
23. Review integration changes: assess subsequent transfers, reorganisations or changes in sponsored employment.
24. Retain evidence: maintain an auditable record of the assessment, notifications, applications and compliance actions.

 

Employers should not treat this checklist as a substitute for analysing the specific transaction.

The Home Office requirements depend on the actual ownership structure, the organisations involved and the circumstances of affected sponsored workers.

Where the transaction is complex or involves material sponsorship risks, the immigration assessment should be completed before the parties commit to the final implementation arrangements.

Section H: Common Ownership and Control Scenarios

 

The sponsor licence consequences of a corporate transaction depend on its legal structure rather than the commercial terminology used to describe it. A share acquisition, management buyout, group restructuring or business transfer may produce different outcomes, even where the business continues operating under the same name and employing the same workforce.

The Home Office Workers and Temporary Workers sponsor guidance contains specific provisions and examples concerning changes in direct ownership, changes in ultimate ownership, the introduction of holding companies and transfers of sponsored workers.

Employers should examine the transaction against those provisions before determining whether the existing licence can continue, whether a new licence application is required and which notifications must be submitted.

The following scenarios illustrate common arrangements and the sponsor licensing questions they create. They are intended to explain the relevant distinctions rather than replace an assessment of the actual transaction.

 

1. Scenario One: Sale of controlling shares to a new owner

 

Transaction: Company A is a UK trading company holding a Skilled Worker sponsor licence. An investor purchases a controlling shareholding in Company A.

Following completion, Company A remains incorporated under the same company number. It continues operating from the same premises, employing the same workforce and performing the same commercial activities.

The investor becomes the new controlling shareholder, but the sponsoring company itself has not been replaced by another legal entity.

Sponsor licence implications

This is a direct ownership change.

The Home Office sponsor guidance includes an example in which a company transfers its controlling shares to a new individual while continuing to trade unchanged. In that example, the company must report the ownership change and apply for a new sponsor licence within 20 working days.

The fact that Company A retains its legal identity and employment contracts does not remove the applicable sponsor licensing requirements.

Employers should not assume that a share acquisition is immigration-neutral simply because there has been no transfer of employees.

Sponsored workers

The workers may remain employed by Company A under their existing employment contracts. However, the employer must address the consequences of the direct ownership change for the sponsor licence under which those workers are sponsored.

The transaction should not be treated as automatically requiring every worker to make a new immigration application. The employer must instead establish the licensing arrangements and any worker-specific requirements arising under the applicable guidance.

Employer action

 

• Confirm that the transaction constitutes a relevant direct ownership change.
• Identify the reporting and new licence application requirements.
• Calculate the applicable 20-working-day deadlines.
• Prepare the required corporate evidence and ownership information.
• Review incoming owners and directors for relevant sponsor suitability concerns.
• Confirm arrangements for continuing sponsorship of existing workers.
• Review sponsor key personnel and SMS access after completion.

 

Key risk: assuming that the existing sponsor licence automatically continues because the same company remains the legal employer.

 

2. Scenario Two: Management buyout of a licensed sponsor

 

Transaction: Company A holds a sponsor licence and is owned by an external shareholder. Its existing management team acquires the controlling shares through a management buyout.

The company continues trading as before, and its sponsored employees remain in their existing roles.

The new owners may already be directors or senior managers of Company A.

Sponsor licence implications

A management buyout should not automatically be treated as exempt from the Home Office ownership-change requirements merely because the purchasers are already involved in running the business.

Where the transaction involves a relevant transfer of controlling shares, it may constitute a direct ownership change requiring notification and a new sponsor licence application under section C4.

The existing managers’ familiarity with the business does not determine whether the ownership-change provisions apply.

The employer must examine the actual shareholding arrangements before and after completion.

Sponsored workers

Employees may remain with the same legal employer, but the company must establish whether its existing sponsor licence is affected by the change in direct ownership.

The organisation should also confirm that its sponsor management arrangements remain suitable following the buyout.

Employer action

 

• Identify the shareholders before and after the buyout.
• Determine whether the transaction triggers the direct ownership provisions.
• Complete the required reporting and any new licence application.
• Review the sponsor suitability implications of the new ownership arrangements.
• Confirm the Authorising Officer and other sponsor key personnel.
• Document the continued employment and sponsorship arrangements for affected workers.

 

Key risk: treating a management buyout as a routine internal management change rather than assessing the transfer of corporate control.

 

3. Scenario Three: Acquisition of the ultimate parent company

 

Transaction: Company A is a UK licensed sponsor wholly owned by Company B. Company B is owned by Company C, the ultimate parent company.

An external purchaser acquires Company C.

Following completion, Company A remains directly owned by Company B. Company A continues trading, and its sponsored workers remain employed by Company A.

The change occurs further up the corporate ownership chain.

Sponsor licence implications

This is an example of a change in indirect ownership or ultimate control.

The Home Office sponsor guidance recognises circumstances in which the ultimate parent changes while the sponsor’s immediate ownership, operations and employment arrangements remain unchanged.

In the relevant guidance example, the change must be reported, but a new sponsor licence is unlikely to be required where the applicable conditions are satisfied.

This is different from a direct ownership change involving the sponsor’s immediate shareholder or holding company.

Employers should not assume that every ultimate parent acquisition produces the same outcome. The actual structure and consequences of the transaction must be examined.

Sponsored workers

Where Company A remains the legal employer and the applicable conditions are satisfied, the transaction may not require the workers to change sponsor or obtain new immigration permission solely because the ultimate parent has changed.

The employer must nevertheless complete the required reporting and maintain its sponsorship arrangements.

Employer action

 

• Prepare ownership charts showing the full corporate structure before and after completion.
• Confirm that Company A’s immediate owner remains Company B.
• Establish whether any other direct ownership or employment changes occur.
• Report the relevant change within the applicable period.
• Assess whether the transaction raises any additional sponsor suitability or management issues.
• Retain evidence supporting the conclusion on licence continuity.

 

Key risk: confusing a change in ultimate ownership with a change in direct ownership, or assuming that indirect ownership changes never require reporting.

 

4. Scenario Four: Insertion of a new immediate holding company

 

Transaction: Company A holds a UK sponsor licence and is directly owned by Company B.

The corporate group reorganises its structure by introducing Company NewHoldCo between Company A and Company B.

Following the restructuring, Company A is directly owned by NewHoldCo, which is itself owned by Company B.

The ultimate ownership of the group remains unchanged, and Company A continues employing the same sponsored workers.

Sponsor licence implications

The transaction changes the immediate ownership of the sponsoring organisation.

The Home Office guidance includes an example in which a new immediate holding company is introduced even though the ultimate parent remains the same. In that example, a new sponsor licence is required.

This demonstrates that the absence of a change in ultimate beneficial ownership does not automatically preserve the existing licence.

An internal group reorganisation can therefore have material immigration consequences despite there being no external purchaser.

Sponsored workers

The workers may continue to be employed by Company A, but the direct ownership change can affect the sponsor licensing arrangements.

The company must establish the applicable requirements for reporting and obtaining the necessary licence.

Employer action

 

• Identify the change in Company A’s immediate parent.
• Assess the transaction under the direct ownership provisions.
• Determine the requirement for a new sponsor licence application.
• Calculate and comply with the relevant reporting and application deadlines.
• Prepare the corporate structure charts and supporting documents.
• Confirm continued sponsorship arrangements for existing workers.

 

Key risk: assuming that an internal restructuring is exempt from sponsor licensing requirements because ultimate ownership remains unchanged.

 

5. Scenario Five: Internal group restructuring involving several subsidiaries

 

Transaction: An international corporate group operates several UK subsidiaries, including Company A and Company B.

Company A holds a sponsor licence and employs sponsored workers. The group proposes to reorganise its UK operations, potentially changing the ownership of Company A, transferring business activities to Company B or moving employees between subsidiaries.

The ultimate shareholders of the corporate group may remain unchanged.

Sponsor licence implications

The consequences depend on how the restructuring is implemented.

If the transaction changes Company A’s direct ownership, the Home Office provisions concerning direct ownership changes must be considered.

If the transaction changes only ownership higher in the corporate chain, the relevant indirect ownership provisions may apply.

If sponsored workers move from Company A to Company B, the parties must also assess the requirements concerning changes of employing entity and business transfers.

The fact that Company A and Company B belong to the same group does not automatically allow them to share or transfer sponsor licensing authorisation.

Where Company B becomes responsible for sponsored workers, it must hold or obtain the appropriate sponsor licence and satisfy the relevant Home Office conditions.

Sponsored workers

Workers who remain employed by Company A may be affected by changes in its ownership or licence status.

Workers transferring to Company B require a separate assessment of whether the transfer qualifies for the applicable TUPE or similar protection provisions.

Where those provisions apply and the conditions are satisfied, new immigration applications and Certificates of Sponsorship may not be required solely because of the transfer.

Where the transfer does not qualify, the ordinary immigration requirements concerning changes of sponsor may apply.

Employer action

 

• Map every legal entity involved in the restructuring.
• Identify the sponsor licence held by each entity.
• Distinguish direct ownership changes from indirect ownership changes.
• Identify any movement of sponsored workers between employers.
• Determine whether each receiving organisation holds the necessary licence.
• Assess the applicability of TUPE or similar protection.
• Prepare separate reporting and application schedules for each relevant organisation.
• Review right to work responsibilities following any transfer of employment.

 

Key risk: treating the corporate group as a single sponsoring organisation when the relevant licences and employment relationships belong to separate legal entities.

 

6. Scenario Six: Business or asset sale involving sponsored workers

 

Transaction: Company A operates a business employing sponsored Skilled Workers.

Company B purchases the business and its assets rather than acquiring the shares in Company A.

As part of the transaction, the employees working in the business transfer from Company A to Company B.

Company B becomes their legal employer following completion.

Sponsor licence implications

Company B cannot automatically acquire Company A’s sponsor licence through the asset purchase.

The receiving organisation must establish whether it already holds the appropriate licence or needs to apply for one.

Where the transfer falls within the relevant Home Office provisions concerning TUPE or similar protection, Company B may be able to assume sponsorship responsibility for the workers without requiring them to make new immigration applications, provided the workers continue in the same sponsored occupation code, with no material change taking the role outside the existing sponsored employment, and the other applicable conditions are satisfied.

Where Company B needs a new sponsor licence or an extension to its existing licence, the Home Office guidance provides a 20-working-day application requirement in relevant circumstances.

The transferring and receiving organisations must also comply with their respective reporting obligations.

Sponsored workers

Where the applicable business transfer conditions are satisfied, the workers may be able to continue their employment without obtaining new Certificates of Sponsorship or immigration permission solely because their employer has changed.

The receiving organisation must accept sponsorship responsibility and comply with the relevant sponsor duties.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

Employer action

 

• Confirm which employees are transferring to Company B.
• Determine whether the transfer falls within TUPE or similar protection.
• Verify Company B’s sponsor licence and relevant sponsorship routes.
• Identify whether a new licence or route extension is required.
• Comply with the applicable 20-working-day application deadline.
• Complete the required notifications for the transferring and receiving organisations.
• Confirm responsibility for sponsorship records and continuing compliance.
• Assess right to work checking obligations following the change in employer.

 

Key risk: assuming that the sponsor licence transfers automatically with the purchased business or that TUPE removes the need to comply with sponsor licensing requirements.

 

7. Scenario Seven: Acquisition followed by a change in directors and sponsor key personnel

 

Transaction: Company A is acquired by a new owner. Following completion, the buyer appoints new directors, replaces senior management and reorganises responsibility for HR and immigration compliance.

The existing Authorising Officer leaves the business, and several employees with Sponsor Management System access are replaced.

Sponsor licence implications

The employer must assess the ownership transaction itself to determine whether the relevant direct or indirect ownership provisions apply.

Separately, it must address any reporting and suitability requirements arising from changes to directors and sponsor key personnel.

These are distinct compliance questions.

The appointment of new directors does not automatically require a new sponsor licence, but the organisation must consider the applicable Home Office requirements and ensure that appropriate sponsor management arrangements remain in place.

Where the acquisition also constitutes a direct ownership change requiring a new licence, the employer must address that requirement independently of the management changes.

Sponsored workers

The workers may continue in their existing roles, but the organisation must maintain effective sponsorship oversight.

The departure of the individuals previously responsible for sponsor compliance should not result in missed reporting deadlines, inadequate record keeping or a failure to respond to Home Office enquiries.

Employer action

 

• Assess the ownership change under the relevant Home Office provisions.
• Identify reportable changes in directors and management.
• Confirm the replacement Authorising Officer and other sponsor key personnel.
• Update SMS access and permissions as required.
• Review the suitability of relevant incoming individuals.
• Ensure continuity of sponsor reporting and record-keeping responsibilities.
• Confirm that sponsored-worker records remain accurate.

 

Key risk: completing the corporate transaction without ensuring that the post-acquisition organisation has appropriate personnel and systems to manage its sponsor duties.

 

8. Scenario Eight: Acquisition involving employees, workers and individual subcontractors

 

Transaction: Company A acquires a business that uses a combination of directly employed staff, sponsored Skilled Workers, individuals engaged under worker contracts and individual subcontractors.

The transaction may be structured as a share acquisition or a business and asset purchase.

Sponsor licence implications

The sponsor licensing consequences depend on whether the transaction changes direct or indirect ownership and whether sponsored employees move to another legal entity.

These questions must be assessed under the relevant Home Office sponsor guidance.

However, the acquisition also requires a separate review of right to work compliance.

Changes effective from 1 October 2026 extended the prescribed right to work checking framework to specified worker contracts and individual subcontractor arrangements.

The buyer should therefore examine the workforce beyond employees holding conventional contracts of employment.

Workforce compliance implications

The employer should establish which organisation is responsible for the prescribed right to work checks, whether existing records are sufficient and whether any follow-up obligations apply.

Where the transaction is a share acquisition and the employing legal entity remains unchanged, the ownership change does not automatically require fresh checks for every individual.

On a qualifying TUPE transfer, the incoming employer obtains the benefit of any statutory excuse established by the outgoing employer, but can inherit exposure where the original check was defective. The Home Office therefore advises fresh checks and allows a 60-calendar-day grace period from the transfer in which to complete them. The grace period does not extend the deadline for any subsequent follow-up check.

Right to work compliance and sponsor licence continuity should be reviewed separately, even where both arise from the same acquisition.

Employer action

 

• Identify the legal structure of the acquisition.
• Assess the relevant sponsor licensing consequences.
• Prepare a complete workforce schedule.
• Identify sponsored employees and their immigration arrangements.
• Review relevant worker and individual subcontractor arrangements.
• Establish responsibility for prescribed right to work checks.
• Review existing checking records and follow-up requirements.
• Investigate any historical illegal working concerns or civil penalties.
• Confirm post-completion sponsor compliance and workforce compliance responsibilities.

 

Key risk: focusing exclusively on sponsored employees while overlooking right to work obligations affecting other categories of workers.

 

9. Ownership and control decision matrix

 

The following matrix summarises the principal sponsor licensing considerations arising from common ownership and control transactions.

It should be read alongside section C4 of the Home Office sponsor guidance. The outcome of any particular transaction depends on its legal structure, the circumstances of the licensed sponsor and the applicable Home Office requirements.

 

Transaction	Principal sponsor licence consideration	Likely required action
Sale of controlling shares in the licensed company	Relevant direct ownership change, even where the legal entity continues unchanged	Report the change and apply for a new sponsor licence within 20 working days where the guidance’s direct ownership provisions apply
Management buyout involving controlling shares	Change in direct ownership notwithstanding continuity of existing management	Assess the direct ownership provisions; report and make a new licence application where required
Change of ultimate parent with immediate owner unchanged	Indirect ownership change; existing operations and employment arrangements may remain unchanged	Report the relevant change; a new licence may not be required where the applicable Home Office conditions are satisfied
Insertion of a new immediate holding company	Change in direct ownership despite unchanged ultimate ownership	New sponsor licence required in the relevant Home Office guidance example, alongside applicable reporting
Internal group restructuring	May affect direct ownership, indirect ownership or the legal entity employing sponsored workers	Assess each change and each licensed entity separately; report and apply for licences where required
Business or asset sale with employee transfer	Receiving organisation becomes the employer; seller’s sponsor licence cannot simply transfer	Confirm receiving sponsor authorisation, assess TUPE or similar protection and comply with relevant reporting and application requirements
Change in directors or sponsor key personnel	Separate management, suitability and reporting obligations	Complete applicable notifications and maintain appropriate sponsor key personnel and SMS arrangements
Acquisition involving workers and individual subcontractors	Separate right to work obligations under the framework effective from 1 October 2026	Assess prescribed checking requirements, statutory excuse records and the organisation responsible for compliance

 

The matrix should not be used to determine the outcome of a transaction without examining the actual ownership and employment arrangements.

In particular, employers should avoid assuming that:

 

• A company can retain its sponsor licence simply because its legal identity remains unchanged.
• Every change in ultimate ownership requires a new licence.
• An internal group restructuring is automatically exempt from the direct ownership provisions.
• A sponsor licence can be transferred through a business or asset purchase agreement.
• TUPE automatically removes the need for sponsor licensing action.
• All changes in directors or management have the same consequences as a change in ownership.
• A change of ownership automatically requires fresh right to work checks for every worker.

 

The appropriate approach is to identify the licensed organisation, map the transaction, determine the applicable Home Office requirements and document the action required.

 

10. Applying the scenarios to complex transactions

 

Real-world acquisitions and restructurings frequently involve more than one of the scenarios described above.

For example, an international group may acquire the controlling shares in a UK sponsor, introduce a new holding company, replace directors and subsequently transfer employees into another subsidiary.

Each step can create a separate sponsor licensing or reporting question.

The initial acquisition may engage the direct ownership provisions, while the subsequent employee transfer may require consideration of the Home Office rules concerning changes of employing entity.

Changes in directors and sponsor key personnel may create additional reporting requirements.

The employer must also consider whether the transaction affects right to work compliance, particularly where the post-acquisition business uses a combination of employees, workers and individual subcontractors.

Where a transaction is implemented in stages, the parties should identify the relevant event and deadline for each required Home Office action.

They should not assume that a notification submitted for the initial acquisition covers every later restructuring or workforce change.

For complex transactions, employers should prepare a consolidated immigration compliance schedule identifying:

 

1. Every legal entity involved in the transaction.
2. Each relevant sponsor licence.
3. The direct and indirect ownership changes at each stage.
4. Any changes in the employing entity of sponsored workers.
5. The applicable reporting requirements.
6. Any required new sponsor licence applications or route extensions.
7. The relevant 20-working-day deadlines.
8. Any supporting evidence submission requirements.
9. The sponsored workers affected by each stage.
10. The right to work compliance responsibilities of the post-transaction organisations.
11. The individuals responsible for completing each action.
12. The records required to demonstrate compliance.

 

This approach helps employers distinguish between the different legal consequences of a transaction and reduces the risk of overlooking a requirement because the commercial transaction has been described as a single acquisition or reorganisation.

Where the proposed arrangements are uncertain, the sponsor licensing assessment should be revisited as the transaction structure develops and before completion.

Section I: Common Mistakes Employers Make

 

Changes in ownership and control frequently create sponsor licence problems because the immigration consequences are considered too late in the transaction process. Employers may focus on corporate law, employment arrangements and commercial completion without recognising that the Home Office applies separate rules to the continued authorisation of a licensed sponsor.

The most significant mistakes often arise from assumptions about business continuity. A company may retain its legal identity, trading name, workforce and premises after an acquisition, but certain changes in direct ownership can still require a new sponsor licence application.

Other problems arise where employers fail to distinguish between direct and indirect ownership, overlook reporting deadlines, transfer sponsored workers between legal entities without assessing the receiving organisation’s licence or neglect the separate right to work requirements.

Understanding these common errors can help employers identify the necessary immigration action before a transaction creates avoidable compliance risks.

 

1. Assuming the sponsor licence automatically continues after a share sale

 

One of the most common mistakes is assuming that a sponsor licence remains unaffected whenever the sponsoring company continues to exist as the same legal entity.

In a conventional share acquisition, the buyer purchases shares in the company rather than acquiring its business and assets directly.

The company may retain its registration number, employment contracts, commercial agreements and trading operations.

However, corporate continuity does not automatically establish sponsor licence continuity.

Section C4 of the Home Office Workers and Temporary Workers sponsor guidance contains specific requirements for relevant changes in direct ownership.

The guidance includes an example of a company transferring its controlling shares to a new individual while continuing to trade unchanged. In that scenario, the company must report the change and apply for a new sponsor licence within 20 working days.

Employers who overlook this distinction may complete an acquisition without recognising that a new licence application is required.

The resulting problem is not necessarily that the sponsored workers have changed employer. It is that the ownership transaction may affect the organisation’s authority to continue sponsoring them.

How to avoid the mistake

Before completion, identify the licensed sponsor, examine the direct ownership arrangements before and after the transaction and determine whether the applicable Home Office provisions require a new licence application.

Do not rely solely on the fact that the company retains its legal identity.

 

2. Treating direct and indirect ownership changes as equivalent

 

Employers sometimes assume that all changes in corporate ownership produce the same sponsor licensing consequences.

This can lead to two different errors.

The first is assuming that every change in ultimate ownership requires a new sponsor licence, regardless of whether the sponsor’s immediate ownership and operations remain unchanged.

The second is assuming that an internal group restructuring cannot require a new licence because the ultimate beneficial owners remain the same.

The Home Office guidance distinguishes between different levels of corporate ownership.

For example, a change in ultimate parent company may require reporting without necessarily requiring a new sponsor licence where the sponsor’s immediate owner and relevant business arrangements remain unchanged.

By contrast, introducing a new immediate holding company can trigger a new licence requirement even where ultimate ownership remains unchanged.

The relevant distinction is therefore not simply whether the transaction involves an external buyer or an internal group reorganisation.

Employers must establish precisely where ownership changes within the corporate structure.

How to avoid the mistake

Prepare corporate structure charts identifying the sponsor’s immediate shareholders, intermediate holding companies and ultimate parent before and after completion.

Assess the actual change against the relevant Home Office guidance rather than relying on a general description such as group restructuring or change of control.

 

3. Confusing Home Office reporting with a new licence application

 

Another significant mistake is treating the notification of an ownership change as sufficient to resolve every sponsor licensing obligation arising from the transaction.

Under the Home Office guidance, relevant ownership and corporate changes must be reported within no more than 20 working days.

However, certain transactions also require a new sponsor licence application within the applicable 20-working-day period.

These are separate requirements.

Submitting an SMS notification does not constitute a new sponsor licence application.

Similarly, submitting a new licence application does not necessarily discharge every reporting obligation concerning the transaction, sponsor key personnel or sponsored workers.

For example, a company undergoing a relevant direct ownership change may be required both to report the transaction and to apply for a new sponsor licence.

If the employer completes only the notification, it may still have failed to satisfy the separate application requirement.

The same distinction can arise where sponsored workers transfer to a receiving organisation that needs to obtain the appropriate sponsorship authorisation.

How to avoid the mistake

Prepare a compliance schedule that separately identifies each notification, licence application, supporting evidence requirement and sponsored-worker action.

Record the applicable deadline and the individual responsible for completing each task.

 

4. Missing the 20-working-day deadline

 

Ownership transactions often involve several teams, including corporate advisers, directors, finance personnel, HR managers and external consultants.

Immigration responsibilities can be overlooked where no individual has been assigned responsibility for sponsor licensing compliance.

Under section C4 of the Home Office sponsor guidance, relevant ownership and corporate changes must be reported within no more than 20 working days.

Specific transactions also engage a 20-working-day requirement for a new sponsor licence application or an extension to an existing licence.

Employers may miss these deadlines because they calculate the period from the date on which HR becomes aware of the transaction rather than identifying the event that triggers the obligation.

Other problems arise where signing and completion occur on different dates, the transaction is implemented in stages or the parties assume that Companies House filings satisfy the Home Office requirements.

Failure to comply with the applicable deadlines can have consequences for sponsor compliance and, where a required licence application is not made, the immigration position of affected workers.

Employers should also recognise that certain SMS change requests involve separate supporting evidence submission requirements, including an applicable five-working-day period under the relevant guidance.

How to avoid the mistake

Identify the triggering event for each obligation, calculate the deadline and prepare the necessary evidence before completion wherever possible.

Do not assume that submitting Companies House documents or notifying another regulator satisfies the Home Office requirements.

 

5. Assuming a sponsor licence transfers automatically with a business

 

A sponsor licence cannot simply be sold or assigned to another organisation as part of a business acquisition.

This becomes particularly important where the transaction is structured as a business or asset sale rather than a share acquisition.

In a business or asset sale, employees may transfer from the selling organisation to the purchaser or another receiving company.

The receiving organisation may become the legal employer of sponsored workers without holding the sponsor licence under which they were originally sponsored.

For example, Company A sells a business division to Company B. Sponsored workers employed in that division transfer to Company B.

Company B cannot automatically rely on Company A’s sponsor licence merely because it has acquired the business.

The parties must establish whether Company B already holds the appropriate sponsorship authorisation or needs to obtain it.

Where the transfer qualifies under the relevant Home Office provisions concerning TUPE or similar protection, sponsored workers may be able to continue without new immigration applications or Certificates of Sponsorship, provided the applicable conditions are satisfied.

These arrangements do not remove the receiving organisation’s obligation to hold or obtain the necessary sponsor licence.

Where a new licence or extension is required, the applicable 20-working-day application deadline must be observed.

How to avoid the mistake

Identify the legal employer of each sponsored worker before and after completion.

Confirm the receiving organisation’s licence position and assess the applicable business transfer provisions before employees move between entities.

 

6. Overlooking changes to directors and sponsor key personnel

 

An ownership transaction may be accompanied by substantial changes in management.

Existing directors may leave, new directors may be appointed and responsibility for HR or immigration compliance may move to a different team.

Employers sometimes focus on the ownership notification without considering the separate obligations arising from changes to sponsor key personnel.

The Authorising Officer, Key Contact and authorised SMS users perform important functions within the sponsor management framework.

Where these individuals leave the business or change roles, the employer must assess the relevant Home Office requirements and maintain appropriate arrangements for managing its sponsor licence.

A failure to maintain effective sponsor management arrangements can result in missed reporting obligations, inadequate record keeping and difficulty responding to Home Office enquiries.

The organisation should also consider whether newly appointed directors or other relevant individuals raise sponsor suitability issues.

These questions are separate from whether the ownership transaction itself requires a new sponsor licence.

How to avoid the mistake

Include sponsor key personnel and SMS access in the completion checklist.

Confirm that appropriate individuals remain responsible for sponsorship duties and complete the required changes to the organisation’s sponsor records.

 

7. Neglecting the position of sponsored workers

 

Corporate transactions can affect sponsored workers even where the commercial objective is simply to acquire or reorganise a business.

Employers may assume that workers can continue in their existing roles without considering whether their sponsor licence arrangements remain appropriate.

This is particularly problematic where employees transfer to another legal entity.

Under the Home Office guidance, qualifying transfers involving TUPE or similar protection can permit sponsored workers to continue without new immigration applications or Certificates of Sponsorship where the relevant conditions are satisfied.

However, these provisions require the receiving organisation to meet the applicable sponsorship requirements.

Where the transfer does not qualify, the ordinary immigration rules concerning changes of sponsor may apply.

Employers should also assess whether the transaction changes sponsored workers’ duties, salaries, work locations or other relevant employment circumstances.

Such changes may create separate reporting or immigration requirements.

A further mistake is assuming that an employee’s existing immigration permission guarantees continued sponsorship regardless of the licensing position of the receiving organisation.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

How to avoid the mistake

Prepare a worker-level immigration schedule before completion.

Identify each worker’s existing sponsor, legal employer, immigration route, permission expiry date and proposed post-transaction arrangements.

Assess the licensing and immigration requirements for each affected group of workers.

 

8. Assuming existing right to work arrangements are automatically compliant

 

Employers should not confuse sponsor licence authorisation with compliance under the right to work checking framework.

Holding a sponsor licence does not automatically establish a statutory excuse against liability for illegal working.

The employer must comply with the prescribed checking requirements applicable to the individual and the relevant working arrangement.

Changes effective from 1 October 2026 extended the prescribed right to work checking framework to specified worker contracts and individual subcontractor arrangements.

This means acquisition due diligence should consider a wider range of working arrangements than conventional contracts of employment.

A purchaser may acquire a business that uses employees, sponsored workers, agency personnel and individual subcontractors.

The employer should establish which arrangements fall within the applicable checking requirements and which organisation is responsible for compliance.

Where the transaction is a share acquisition and the employing legal entity remains unchanged, the change in ownership does not automatically require every employee to undergo a fresh right to work check.

However, the employer should still assess whether existing records are sufficient, whether follow-up checks have been completed and whether historical compliance concerns require attention.

On a qualifying TUPE transfer, the incoming employer obtains the benefit of any statutory excuse established by the outgoing employer, but can inherit exposure where the original check was defective. The Home Office therefore advises fresh checks and allows a 60-calendar-day grace period from the transfer in which to complete them. The grace period does not extend the deadline for any subsequent follow-up check.

Failures concerning prescribed right to work checks can expose an organisation to civil penalty risks and may also affect sponsor suitability.

Under the applicable Home Office sponsor guidance, serious right to work compliance failures or a civil penalty for illegal working can have consequences for the organisation’s sponsor licence, including revocation where the relevant grounds are met.

How to avoid the mistake

Conduct a separate right to work compliance review as part of transaction due diligence.

Assess the workforce against the framework effective from 1 October 2026, identify relevant checking and follow-up obligations, and establish responsibility for maintaining the statutory excuse after completion.

 

9. Failing to review the final transaction structure

 

Corporate transactions can change significantly between initial negotiations and completion.

A proposed share acquisition may be restructured to involve a new holding company, an asset purchase or a transfer of employees to another group entity.

These changes can materially alter the sponsor licensing consequences.

For example, an initial assessment may conclude that a transaction involves a change in ultimate parent company while the sponsor’s immediate ownership remains unchanged.

If the final structure introduces a new immediate holding company, the transaction may instead engage the direct ownership provisions requiring a new sponsor licence.

Similarly, a transaction originally expected to leave employees with the same legal employer may subsequently involve their transfer to another organisation.

That change can introduce separate licensing and sponsored-worker requirements.

Employers should not assume that an immigration assessment completed at the start of negotiations remains valid if the transaction structure changes.

How to avoid the mistake

Review the final corporate and employment arrangements immediately before completion.

Update the immigration compliance assessment, reporting schedule and sponsor licence application plan to reflect the actual transaction.

 

10. Treating post-completion integration as outside sponsor compliance

 

The initial acquisition may be only the first stage of a wider corporate reorganisation.

Following completion, the purchaser may consolidate business operations, transfer employees between subsidiaries, change work locations or reorganise management responsibilities.

Each subsequent development may create additional sponsor reporting, licensing or workforce compliance obligations.

Employers sometimes assume that the original ownership notification covers all later changes arising from the acquisition.

This can result in unreported changes to sponsored employment, inaccurate corporate records or failures to reassess the licensing position when employees move to another legal entity.

The employer should also ensure that right to work records and monitoring responsibilities are not lost during the integration of HR systems.

Where sponsored workers have time-limited immigration permission, responsibility for monitoring expiry dates and follow-up checks should remain clearly allocated.

How to avoid the mistake

Maintain a post-completion immigration compliance plan covering further corporate changes, sponsor key personnel, sponsored-worker arrangements and right to work responsibilities.

Assess each material integration step against the applicable Home Office requirements rather than assuming that the original transaction assessment remains sufficient.

 

11. Failing to retain evidence of the ownership-change assessment

 

Employers should retain evidence demonstrating how they assessed the sponsor licensing consequences of a transaction and what action was taken.

A business may correctly identify the relevant requirements but later encounter difficulties if the supporting documents, notifications or internal decisions cannot be located.

This can become important during a Home Office compliance visit, a subsequent acquisition or a future sponsor licence application.

Relevant records may include corporate structure charts, transaction documents, evidence of ownership changes, SMS notifications, sponsor licence applications and correspondence with the Home Office.

Where sponsored workers transfer between organisations, the employer should retain evidence of the relevant employment arrangements, sponsorship responsibilities and reporting action.

Right to work records should also be maintained in accordance with the applicable requirements.

How to avoid the mistake

Maintain a central transaction compliance file recording the legal analysis, required actions, submission dates, supporting evidence and Home Office decisions.

Ensure that the records remain accessible after changes in ownership, management or HR systems.

 

12. Leaving immigration compliance until after completion

 

Perhaps the most avoidable mistake is treating sponsor licensing as a post-completion administrative matter.

By the time the transaction completes, the parties may already be committed to ownership and employment arrangements that trigger specific Home Office requirements.

Where a new sponsor licence application is required, the employer may have limited time to prepare the necessary evidence and submit the application within the prescribed period.

Where sponsored workers transfer to another organisation, the receiving employer may need to satisfy the applicable licensing requirements before the transaction can be managed safely from an immigration perspective.

Historical sponsor compliance or right to work problems may also emerge too late to be addressed properly within the transaction timetable.

Immigration compliance should therefore be considered during transaction structuring and due diligence, not simply after the corporate documents have been signed.

How to avoid the mistake

Include sponsor licensing and right to work compliance in the transaction workstreams from the outset.

Identify the relevant legal entities, ownership changes, sponsored workers, reporting obligations and new licence requirements before completion.

Allocate responsibility for the necessary Home Office action and maintain a documented post-completion compliance plan.

Early assessment can help employers protect sponsorship continuity, meet the applicable deadlines and reduce the risk of disruption to the workforce following a change in ownership or control.

Section J: How DavidsonMorris Can Help

 

Changes in company ownership or control can have significant consequences for an employer’s sponsor licence and its ability to continue employing sponsored workers. The immigration requirements depend on the transaction structure, the legal identity of the sponsoring organisation, the nature of the ownership change and whether sponsored employees will remain with their existing employer or transfer to another entity.

DavidsonMorris advises UK employers on sponsor licence requirements arising from corporate acquisitions, changes in ownership, group restructurings and business transfers.

Our business immigration and workforce compliance solicitors help employers identify the relevant Home Office obligations, assess the implications for existing sponsorship arrangements and plan the actions required before and after completion.

We work with business owners, directors, HR teams, in-house legal departments and corporate advisers to address immigration compliance as part of the wider transaction process.

 

1. Sponsor licence advice before an acquisition or restructuring

 

We advise employers on the sponsor licensing implications of proposed changes in ownership and control, including direct share acquisitions, management buyouts, changes in ultimate ownership and internal group reorganisations.

Our advice focuses on the legal structure of the transaction and the requirements under the current Home Office sponsor guidance.

This includes assessing whether the existing sponsor licence can continue, whether a new application is required and which reporting obligations apply.

Where the transaction involves the introduction of a new holding company or changes to the immediate ownership of a licensed sponsor, we can advise on the potential requirement for a new licence and the applicable application timetable.

We can also review proposed corporate structures before completion to identify immigration consequences that may not be apparent from the commercial arrangements alone.

 

2. Home Office reporting and new sponsor licence applications

 

Where a transaction triggers Home Office reporting or licensing requirements, we can advise on the necessary steps and assist with their implementation.

This includes identifying relevant ownership and corporate changes, establishing the applicable reporting deadlines and preparing supporting evidence.

Where a new sponsor licence application is required following a direct ownership change or qualifying business transfer, we can assist with the application process and the associated compliance requirements.

Our advice also addresses the distinction between the obligation to notify the Home Office and any separate requirement to obtain new sponsorship authorisation.

We can support employers in preparing the corporate information, ownership evidence and organisational documentation required for the relevant application or notification.

 

3. Protecting sponsored workers during business transfers

 

Where a transaction affects employees sponsored under the Skilled Worker route or another sponsored immigration category, we can advise on the consequences for their existing immigration arrangements.

This includes assessing whether employees will remain with the same legal employer or transfer to another organisation.

Where workers transfer under TUPE or similar protection, we can advise on the relevant Home Office provisions and the conditions under which new immigration applications or Certificates of Sponsorship may not be required.

We can also assess whether the receiving organisation holds the appropriate sponsor licence, whether a new licence or route extension is necessary and which reporting obligations apply.

Where employees move outside the qualifying business transfer provisions, we can advise on any additional sponsorship or immigration applications required.

Our objective is to help employers manage the transaction without avoidable disruption to the lawful employment of sponsored workers.

 

4. Sponsor compliance and right to work due diligence

 

We can assist employers and prospective purchasers with immigration compliance due diligence before a transaction completes.

This may include reviewing the target organisation’s sponsor licence status, sponsored workforce, key personnel arrangements, reporting history and relevant Home Office correspondence.

We can also advise on right to work compliance, including the prescribed checking framework effective from 1 October 2026 and its application to relevant worker contracts and individual subcontractor arrangements.

Where due diligence identifies potential breaches or weaknesses, we can advise on the immigration implications and appropriate remedial action.

For employers acquiring a business with an existing sponsored workforce, this assessment can help identify risks affecting sponsor suitability, continued sponsorship and post-completion compliance.

 

5. Post-completion sponsor licence and workforce compliance

 

Following completion, we can advise on the steps required to align the organisation’s sponsorship arrangements with its new corporate structure.

This may include changes to sponsor key personnel, updates to Home Office records, reporting of sponsored-worker changes and review of the legal entities responsible for sponsorship.

We can also support employers where post-acquisition integration involves further reorganisations, changes in employing entity or transfers of sponsored workers between group companies.

Where the Home Office raises questions about the transaction or the organisation’s compliance arrangements, we can advise on the appropriate response.

Employers planning a change in ownership or control should obtain immigration advice before completion wherever possible, particularly where the transaction affects a licensed sponsor or employees whose right to work depends on sponsorship.

Section K: Conclusion

 

A change in company ownership or control can have significant consequences for an employer’s sponsor licence, even where the business continues operating under the same name, employing the same workforce and carrying out the same activities.

The Home Office applies specific requirements to changes in direct and indirect ownership, corporate restructurings and transfers of sponsored workers. Employers must therefore assess the legal structure of the transaction rather than assuming that continuity of the business automatically preserves its existing sponsorship arrangements.

Under the Home Office sponsor guidance, certain direct ownership changes require the organisation to report the transaction and apply for a new sponsor licence within 20 working days. Changes in ultimate ownership may be treated differently where the sponsor’s immediate ownership and relevant business arrangements remain unchanged. Introducing a new immediate holding company can also trigger a new licence requirement, notwithstanding continuity of ultimate ownership.

Where sponsored workers transfer to another legal employer, the receiving organisation must establish whether it holds the appropriate sponsor licence and whether the transfer falls within the Home Office provisions concerning TUPE or similar protection. Where the relevant conditions are satisfied, workers may be able to continue without obtaining new immigration permission or Certificates of Sponsorship solely because of the transfer. However, the applicable licensing, reporting and sponsorship requirements must still be met.

Employers should also address the separate right to work obligations arising from a transaction, including the expanded prescribed checking framework effective from 1 October 2026 for specified worker contracts and individual subcontractor arrangements. Sponsor licence compliance and the statutory excuse against liability for illegal working are distinct legal requirements, and both should form part of transaction due diligence.

The most effective approach is to identify the immigration consequences before completion, establish the relevant Home Office reporting and application deadlines, assess the position of affected sponsored workers and maintain a documented compliance plan throughout the transaction and subsequent business integration.

For employers, the central principle is that a change in ownership or control must be assessed for its sponsor licensing consequences before the transaction is implemented. Early planning can help protect sponsorship continuity, reduce compliance risks and avoid unnecessary disruption to the employment of overseas workers.

Section L: Frequently Asked Questions

 

Does a sponsor licence transfer automatically when a company is sold?

No. A sponsor licence does not automatically transfer to a purchaser when a company or business is sold. The consequences depend on the legal structure of the transaction and the nature of the ownership change.

Where a purchaser acquires controlling shares in the licensed company, the company may remain the same legal entity and continue employing its existing workforce. However, the Home Office sponsor guidance contains specific requirements for relevant changes in direct ownership, including circumstances in which a new sponsor licence application is required within 20 working days.

Where the transaction is structured as a business or asset sale and sponsored workers transfer to another legal employer, the receiving organisation must establish whether it holds the appropriate sponsor licence or needs to obtain one.

Employers should assess the licensing consequences before completion rather than assuming that the existing licence follows the business or remains valid because the company continues trading.

 

Do we need a new sponsor licence if the company’s shareholders change?

A change in shareholders can require a new sponsor licence, particularly where the transaction involves a relevant change in direct ownership or control.

The Home Office sponsor guidance includes an example in which a company transfers its controlling shares to a new individual while continuing to trade as before. In that scenario, the company must report the change and apply for a new sponsor licence within 20 working days.

However, not every change in shareholding necessarily produces the same outcome. The employer must establish the nature of the change, the level at which ownership is affected and the applicable Home Office provisions.

The assessment should distinguish between changes in direct ownership, changes in indirect ownership and other changes in the corporate structure.

 

What is the difference between direct and indirect ownership for sponsor licensing?

Direct ownership concerns the person or organisation that owns the licensed sponsor at the immediate shareholder or parent-company level. Indirect ownership concerns ownership or control exercised through other companies further up the corporate structure.

The distinction is important because the Home Office guidance treats different ownership changes differently.

For example, a relevant transfer of controlling shares in the sponsoring company can require a new sponsor licence application.

By contrast, where the ultimate parent company changes but the sponsor’s immediate owner and relevant business arrangements remain unchanged, the change may require reporting without necessarily requiring a new licence.

The employer should prepare corporate structure charts showing the position before and after the transaction and assess the actual change against the relevant guidance.

 

Does an internal group restructuring require a new sponsor licence?

It can. An internal restructuring is not automatically exempt from the Home Office ownership-change requirements merely because the ultimate shareholders remain unchanged.

The sponsor guidance includes an example in which a new immediate holding company is inserted into the corporate structure. Although the ultimate parent remains the same, the change in direct ownership requires a new sponsor licence.

Other group restructurings may affect only indirect ownership or may involve transferring sponsored workers between legal entities.

The consequences depend on the actual arrangements. Employers should identify the licensed sponsor, the ownership changes and any movement of sponsored workers before determining the required Home Office action.

 

How long do employers have to report a change in ownership or control?

Under section C4 of the Home Office Workers and Temporary Workers sponsor guidance, relevant changes in ownership and corporate circumstances must be reported within no more than 20 working days.

The employer should identify the event that triggers the reporting obligation and calculate the deadline accordingly.

Where a transaction is signed on one date and completes on another, or is implemented in stages, the relevant effective date should be established for each reportable change.

Employers should also distinguish the reporting deadline from any separate requirement to apply for a new sponsor licence.

Certain changes require both notification and a new licence application within the applicable 20-working-day period.

For an ownership-change request made through the relevant SMS function, the sponsor must complete and send the submission sheet, together with any required supporting evidence, within 5 working days.

 

What happens if we fail to report a change in ownership?

Failure to report a relevant ownership or control change within the prescribed period can constitute a breach of sponsor duties.

The consequences depend on the nature of the change, the organisation’s circumstances and whether other Home Office requirements have also been missed.

For example, an employer may fail to report a direct ownership change and also overlook a separate requirement to apply for a new sponsor licence.

These are distinct compliance issues and should be assessed separately.

Home Office action may include further enquiries or compliance measures where the applicable grounds are met. In more serious circumstances, the organisation’s ability to continue sponsoring workers may be affected.

Where an employer discovers an unreported change, it should establish the relevant facts, identify all outstanding obligations and obtain advice on the appropriate corrective action.

 

Can sponsored employees continue working after a change of ownership?

Sponsored employees may be able to continue working after a change of ownership, but the employer must establish whether the transaction affects the sponsor licence or the legal entity responsible for their employment.

Where employees remain with the same legal employer following a share acquisition, the company must assess the sponsor licensing consequences of the ownership change. Certain direct ownership changes require a new licence application even though the employment relationship continues.

Where employees transfer to another organisation under TUPE or similar protection, the Home Office guidance provides arrangements under which they may be able to continue without obtaining new immigration permission or Certificates of Sponsorship.

Those arrangements depend on the receiving organisation satisfying the relevant licensing, sponsorship and reporting requirements.

Employers should therefore review the immigration position of affected workers before completion and avoid assuming that continued employment automatically resolves the sponsorship requirements.

 

Do sponsored workers need new visas following a business transfer?

Not necessarily. Where sponsored workers transfer under TUPE or similar protection recognised by the Home Office guidance, they may be able to continue without making new immigration applications or obtaining new Certificates of Sponsorship solely because of the transfer.

The relevant conditions must be satisfied, including the receiving organisation holding or obtaining the appropriate sponsor licence and accepting sponsorship responsibility.

The workers must continue in the same sponsored occupation code, with no material change taking the role outside the existing sponsored employment.

Where the transfer does not qualify for these arrangements, the ordinary immigration requirements concerning changes of sponsor may apply.

Depending on the route and circumstances, this may require a new Certificate of Sponsorship and an application for updated immigration permission.

Employers should assess the position of each affected worker rather than assuming that all employees transferring under a commercial transaction have the same immigration requirements.

 

Does TUPE automatically transfer sponsorship responsibility?

No. TUPE and the Home Office sponsorship framework address different legal questions.

TUPE may provide for the transfer of employment rights and obligations between employers, but it does not automatically transfer a sponsor licence from the outgoing employer to the receiving organisation.

The receiving organisation must satisfy the relevant Home Office requirements, including holding or obtaining appropriate sponsorship authorisation and accepting responsibility for the affected sponsored workers.

Where the applicable conditions are met, including the workers continuing in the same sponsored occupation code with no material change taking the role outside the existing sponsored employment, the Home Office guidance can allow workers to continue without new immigration applications or Certificates of Sponsorship solely because of the transfer.

The transferring and receiving organisations must also comply with their respective reporting obligations.

Employers should therefore assess the employment law position and the immigration sponsorship requirements separately.

 

What if the receiving company does not have a sponsor licence?

Where sponsored workers transfer to an organisation that does not hold the appropriate sponsor licence, the receiving employer must establish whether it is required to apply for a new licence under the relevant Home Office business transfer provisions.

In qualifying circumstances, the guidance provides a 20-working-day period for making the required application.

Where the receiving organisation already holds a sponsor licence but is not authorised under the relevant immigration route, it may need to apply for an extension to its existing licence.

The application must satisfy the applicable eligibility and suitability requirements.

If the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

The parties should therefore establish the receiving organisation’s licence position before the transfer takes effect and incorporate the required action into the transaction timetable.

 

Can sponsored workers move between companies in the same corporate group?

Sponsored workers cannot automatically move between group companies simply because those organisations share common ownership.

The immigration consequences depend on the legal entities involved, the relevant sponsor licences and the circumstances of the proposed transfer.

Where the movement forms part of a qualifying business transfer under TUPE or similar protection, the Home Office guidance may permit continued sponsorship without new immigration applications, provided the workers continue in the same sponsored occupation code, with no material change taking the role outside the existing sponsored employment, and the other applicable conditions are met.

Where a worker moves to another group company outside those provisions, the ordinary requirements concerning changes of sponsor may apply.

Employers should establish whether the receiving organisation is appropriately licensed and whether a new Certificate of Sponsorship or immigration application is required.

Common ownership does not, by itself, remove these obligations.

 

Does a change of directors affect a sponsor licence?

A change of directors does not automatically have the same consequences as a change in ownership or control, but it may create separate reporting and sponsor suitability obligations.

Employers must consider the relevant Home Office requirements concerning changes in management and the individuals associated with the licensed organisation.

Where the transaction also results in changes to the Authorising Officer, Key Contact or authorised SMS users, the organisation must ensure that appropriate sponsor management arrangements remain in place.

Incoming directors or other relevant individuals may also need to be considered as part of the sponsor suitability assessment.

Where the appointment of new directors accompanies a share acquisition, the employer should assess both the ownership transaction and the management changes rather than assuming that one notification addresses every obligation.

 

Does a change of ownership require new right to work checks?

Not automatically. The right to work requirements depend on the legal employer, the individual’s immigration status and the applicable checking framework.

Where a share acquisition leaves the employing legal entity unchanged, the change in ownership does not, by itself, mean that every employee must undergo a fresh right to work check.

The employer must nevertheless ensure that its existing checks and records comply with the applicable requirements and that any necessary follow-up checks are completed.

On a qualifying TUPE transfer, the incoming employer obtains the benefit of any statutory excuse established by the outgoing employer, but can inherit exposure where the original check was defective. The Home Office therefore advises fresh checks and allows a 60-calendar-day grace period from the transfer in which to complete them. The grace period does not extend the deadline for any subsequent follow-up check.

Right to work compliance should be considered separately from sponsor licence continuity.

Employers should not assume that holding a sponsor licence or completing an ownership notification automatically establishes a statutory excuse against liability for illegal working.

 

How do the 1 October 2026 right to work changes affect acquisitions?

Changes effective from 1 October 2026 extended the prescribed right to work checking framework to specified worker contracts and individual subcontractor arrangements, in addition to conventional employment relationships.

For businesses undertaking acquisitions or restructurings, this means workforce compliance due diligence should consider a wider range of working arrangements.

A purchaser should identify employees, relevant workers and individual subcontractors and establish which arrangements fall within the applicable prescribed checking requirements.

The review should also consider existing checking records, immigration permission expiry dates, follow-up obligations and responsibility for compliance after completion.

These requirements do not mean that every ownership change automatically triggers fresh checks for every individual.

Rather, the employer must assess the applicable framework, the nature of the working arrangement and whether the legal employer or responsible organisation changes as part of the transaction.

Failures to comply with right to work requirements can create civil penalty exposure and may also have consequences for sponsor suitability.

 

Can the Home Office revoke a sponsor licence following a change of ownership?

A change of ownership can affect the status of a sponsor licence under the specific Home Office provisions governing corporate changes.

Where the transaction constitutes a relevant change in direct ownership under C4.5, the existing licence will be revoked or, where sponsored workers have transferred under the relevant arrangements, made dormant.

This should be distinguished from revocation imposed because an organisation has breached its sponsor duties.

Where an employer fails to report relevant changes, does not make a required new licence application or breaches other sponsor obligations, the Home Office may consider compliance action under the applicable guidance.

Other matters, including serious right to work compliance failures or relevant civil penalties for illegal working, can also expose an organisation to sponsor licence consequences.

Employers should not assume that every change of ownership results in revocation. The outcome depends on the transaction structure, the applicable Home Office provisions and the organisation’s compliance position.

 

What documents are needed to report a change of ownership?

The documents required depend on the nature of the transaction and the Home Office procedure being followed.

Relevant evidence may include corporate structure charts, share transfer documentation, Companies House records, details of the new ownership arrangements and documents identifying the legal entities involved.

Where the transaction involves a business transfer, additional evidence may be required concerning the transfer arrangements and affected sponsored workers.

Where a new sponsor licence application is necessary, the organisation must satisfy the applicable documentary requirements for that application.

Employers should distinguish between evidence required to support an ownership notification and documents required for a new licence application.

Certain SMS change requests also have specific supporting evidence submission requirements and deadlines.

The organisation should follow the applicable Home Office instructions and retain copies of the documents and submissions for its compliance records.

 

Should immigration due diligence be completed before an acquisition?

Yes. Where the target business holds a sponsor licence or employs sponsored workers, immigration due diligence should be completed before the transaction wherever possible.

The review should establish the status of the sponsor licence, the existing ownership structure, the sponsored workforce and any relevant compliance history.

It should also determine whether the proposed acquisition requires Home Office reporting, a new sponsor licence application or changes to sponsorship responsibility.

Where sponsored workers will transfer between legal entities, the parties should assess whether the relevant TUPE or similar protection provisions apply and whether the receiving organisation holds the appropriate licence.

Right to work compliance should also be examined, including the framework effective from 1 October 2026 for specified worker contracts and individual subcontractor arrangements.

Early due diligence can help identify issues that may affect the transaction structure, completion timetable and post-acquisition integration arrangements.

 

Who is responsible for reporting ownership changes after an acquisition?

The licensed sponsor remains responsible for complying with the Home Office reporting requirements applicable to its organisation.

Where a transaction involves more than one licensed sponsor, each organisation should establish its own obligations.

For example, a business transfer involving sponsored workers may create reporting requirements for both the transferring and receiving organisations.

Corporate advisers, purchasers and sellers may agree commercially who will prepare documents or coordinate the immigration workstream, but those arrangements do not remove the sponsor’s obligations under Home Office guidance.

The parties should allocate responsibility before completion and ensure that the relevant individuals have access to the information and systems needed to complete the required actions.

Evidence of the notifications, applications and supporting documents should be retained.

 

What happens if the Home Office refuses the new sponsor licence application?

Refusal of a required sponsor licence application can have serious consequences for the organisation and its sponsored workforce.

The outcome depends on the reason for refusal, the type of transaction and the applicable Home Office provisions.

Where sponsored workers have transferred under qualifying business transfer arrangements, if the required valid application is not made within 20 working days, or the application is refused, the transferred workers will have their permission cancelled, except any workers who can be sponsored under an appropriate existing licence held by the incoming organisation.

A refusal may also prevent the organisation from sponsoring additional overseas workers.

The employer should establish the reason for refusal, the status of the existing licensing arrangements and the immigration position of affected employees.

It should not assume that an unsuccessful application leaves the business free to continue sponsorship under the previous arrangements.

Where a proposed transaction requires a new licence, the risk of refusal should be considered during due diligence and transaction planning.

 

What is the safest way to manage a sponsor licence change of ownership?

The safest approach is to assess the immigration consequences before the transaction completes and maintain a documented plan for meeting the relevant Home Office requirements.

The employer should identify the licensed sponsor, map the direct and indirect ownership changes, determine whether a new licence application is required and establish the applicable reporting deadlines.

Where sponsored workers are affected, the organisation should confirm their legal employer before and after completion, assess the relevant transfer provisions and establish whether any additional immigration action is necessary.

The plan should also address sponsor key personnel, SMS access, supporting evidence and right to work compliance.

Following completion, the employer should verify that the required notifications and applications have been submitted, monitor any Home Office decisions and review subsequent integration changes.

For complex acquisitions, group reorganisations or transactions involving sponsored workers, specialist immigration advice before completion can help reduce the risk of missed deadlines, licensing problems and disruption to the workforce.

Section M: Glossary

 

The following glossary explains the principal terms used in connection with sponsor licence changes of ownership and control. These definitions should be read alongside the applicable Home Office sponsor guidance, immigration legislation and corporate law requirements.

 

Term	Meaning
Sponsor Licence	A sponsor licence is the authorisation granted by the Home Office to an eligible organisation permitting it to sponsor qualifying overseas workers under specified UK immigration routes. The licence is held by the authorised sponsoring organisation and is subject to ongoing eligibility, suitability and compliance requirements. A sponsor licence cannot simply be sold or assigned to another legal entity as part of a corporate transaction. Changes in ownership, control or employing entity must be assessed under the relevant Home Office provisions.
Licensed Sponsor	A licensed sponsor is an organisation authorised by the Home Office to sponsor workers under one or more immigration routes. The licensed sponsor is responsible for complying with the relevant sponsorship duties, including record keeping, reporting changes, monitoring sponsored workers and maintaining appropriate compliance systems. Where a corporate group contains several companies, the sponsor licensing position of each relevant legal entity must be established.
Change of Ownership	A change of ownership occurs where the ownership interests in a company or business change, including through a sale of shares, acquisition, management buyout or corporate restructuring. For sponsor licensing purposes, the consequences depend on the nature of the transaction and the level within the corporate structure at which ownership changes. Certain changes in direct ownership require a new sponsor licence application, even where the licensed company continues operating as the same legal entity.
Change of Control	A change of control involves a change in the person or organisation exercising control over a company or its relevant affairs. Control may arise through share ownership, voting rights or other arrangements, depending on the legal context. For sponsor licensing purposes, employers must assess the actual ownership and control arrangements against the applicable Home Office guidance rather than assuming that every corporate definition of control produces the same immigration consequences.
Direct Ownership	Direct ownership concerns the immediate ownership of the licensed sponsoring organisation. For example, where Company A holds a sponsor licence and Company B directly owns its shares, Company B is the immediate owner of Company A. A relevant change in direct ownership can trigger Home Office reporting requirements and a new sponsor licence application. The Home Office guidance includes examples involving the transfer of controlling shares and the introduction of a new immediate holding company.
Indirect Ownership	Indirect ownership concerns ownership or control exercised through one or more intermediate companies in a corporate structure. For example, where Company C owns Company B and Company B owns the licensed sponsor, Company C has an indirect ownership interest in the sponsor. A change in ultimate ownership may require reporting without necessarily requiring a new sponsor licence where the sponsor’s immediate ownership and relevant business arrangements remain unchanged. The outcome depends on the applicable Home Office provisions and the actual transaction structure.
Ultimate Parent Company	The ultimate parent company is the company at the top of a corporate ownership chain, subject to the relevant legal and corporate structure. It may exercise indirect control over subsidiaries through intermediate holding companies. For sponsor licensing purposes, a change in ultimate parent should be distinguished from a change in the immediate ownership of the licensed sponsor. The distinction can affect whether the transaction requires notification only or a new sponsor licence application.
Immediate Holding Company	An immediate holding company is the company that directly owns or controls a subsidiary within a corporate group. Where a licensed sponsor becomes directly owned by a newly introduced holding company, the transaction may constitute a relevant direct ownership change. The Home Office guidance includes an example requiring a new sponsor licence where a new immediate holding company is inserted into the ownership structure, notwithstanding continuity of ultimate ownership.
Controlling Shareholding	A controlling shareholding is an ownership interest that gives a shareholder control over a company under the relevant legal and corporate arrangements. Control may be associated with a majority of voting rights, although the legal analysis can depend on the rights attached to shares and other relevant arrangements. The Home Office sponsor guidance contains specific examples concerning the transfer of controlling shares. Employers should assess the actual rights and ownership structure rather than assuming that every minority or majority share transaction has identical sponsor licensing consequences.
Corporate Restructuring	Corporate restructuring is the reorganisation of a company’s or corporate group’s ownership, legal entities, operations or management arrangements. Examples include introducing holding companies, transferring subsidiaries between group entities, consolidating business activities and changing the organisations employing workers. A restructuring may affect direct ownership, indirect ownership or the legal employer of sponsored workers. Each relevant change should be assessed separately under the Home Office sponsor guidance.
Share Acquisition	A share acquisition occurs where a purchaser acquires shares in an existing company. The acquired company generally continues to exist as the same legal entity, although its shareholders or controlling owners change. For sponsor licensing purposes, the continuation of the legal entity does not automatically preserve the existing licence. A relevant change in direct ownership can require notification and a new sponsor licence application under the applicable Home Office provisions.
Business or Asset Acquisition	A business or asset acquisition involves the purchase of specified business operations, assets or activities rather than necessarily acquiring the shares in the company that owns them. The transaction may involve employees transferring from the seller to the purchaser or another receiving organisation. Where sponsored workers transfer to a different legal employer, the receiving organisation must establish whether it holds or needs to obtain the appropriate sponsor licence. The seller’s sponsor licence does not automatically transfer with the purchased business.
TUPE	TUPE refers to the Transfer of Undertakings (Protection of Employment) Regulations 2006, which provide employment protections in qualifying business transfers and service provision changes. Where sponsored workers transfer under TUPE or similar protection, the Home Office sponsor guidance contains provisions that may allow them to continue without obtaining new immigration permission or Certificates of Sponsorship solely because of the transfer. The receiving organisation must satisfy the relevant sponsorship requirements, including holding or obtaining appropriate authorisation and accepting sponsorship responsibility. TUPE does not automatically transfer a sponsor licence between organisations.
Receiving Organisation	The receiving organisation is the employer or other relevant entity to which a business, undertaking or workforce transfers. Where sponsored workers transfer, the receiving organisation must establish its obligations under the Home Office sponsorship framework. Depending on the circumstances, it may need to hold an existing sponsor licence, apply for a new licence or obtain authorisation under an additional immigration route. It must also comply with the applicable requirements for accepting sponsorship responsibility and reporting the transfer.
Sponsorship Responsibility	Sponsorship responsibility refers to the duties undertaken by a licensed sponsor in relation to workers it sponsors under the relevant immigration routes. These duties include maintaining required records, monitoring sponsored employment, reporting specified changes and complying with the Home Office sponsor guidance. Where workers transfer under qualifying business transfer arrangements, the receiving organisation must accept the relevant sponsorship responsibilities in accordance with the applicable provisions. The transfer of employment and the assumption of sponsorship responsibility are connected but legally distinct matters.
Certificate of Sponsorship (CoS)	A Certificate of Sponsorship is an electronic sponsorship record assigned by an authorised sponsor to support a worker’s immigration application under an eligible sponsored route. It contains information relevant to the sponsored employment and immigration application. Where workers transfer under TUPE or similar protection and the applicable Home Office conditions are satisfied, they may not require new Certificates of Sponsorship solely because their employment transfers. Where a worker changes sponsor outside the relevant transfer provisions, a new Certificate of Sponsorship and immigration application may be required.
Sponsor Management System (SMS)	The Sponsor Management System is the Home Office online system used by licensed sponsors to manage specified sponsorship functions. These include assigning Certificates of Sponsorship, reporting relevant organisational and worker changes and maintaining certain sponsor information. Ownership and control changes may require notifications through the appropriate SMS procedures. Employers should ensure that authorised users remain available to manage required actions during and after a corporate transaction.
Authorising Officer	The Authorising Officer is the individual designated by a licensed sponsor to take overall responsibility for the organisation’s sponsorship arrangements and compliance with sponsor duties. The individual must satisfy the applicable Home Office requirements for the role. Where an acquisition or restructuring results in the departure or replacement of the Authorising Officer, the organisation must comply with the relevant requirements for maintaining and updating its sponsor key personnel arrangements.
Key Contact	The Key Contact is the individual designated as the principal point of contact for relevant Home Office communications concerning the sponsor licence. The role is separate from that of the Authorising Officer and SMS users, although the same individual may be permitted to hold more than one role where the applicable requirements are satisfied. Changes to the Key Contact following an acquisition or restructuring should be assessed against the Home Office reporting and appointment requirements.
Level 1 User	A Level 1 User is an authorised individual with access to the Sponsor Management System and permissions to perform specified sponsorship management functions. The organisation must maintain appropriate SMS access arrangements and comply with the relevant eligibility and appointment requirements. Where a corporate transaction results in the departure of existing Level 1 Users, the employer should review access permissions and arrange replacements as required.
Sponsor Suitability	Sponsor suitability concerns whether an organisation meets the Home Office requirements to be granted or retain a sponsor licence. The assessment can involve the organisation’s compliance history, relevant individuals associated with it and other matters specified in the sponsor guidance. Changes in ownership or management may introduce circumstances requiring consideration under the applicable suitability provisions. A sponsor licence previously granted to an organisation does not remove the need to consider relevant suitability issues arising from subsequent corporate changes.
Sponsor Licence Revocation	Sponsor licence revocation is the termination of a sponsor’s authorisation by the Home Office under the applicable sponsor guidance. Revocation may arise from serious sponsor compliance breaches or other circumstances specified in the guidance. The Home Office provisions concerning ownership changes can also affect the status of an existing licence, including circumstances in which it may be revoked or made dormant as part of the transaction-related licensing arrangements. Employers should distinguish these ownership-related consequences from punitive revocation arising from sponsor non-compliance.
Right to Work Check	A right to work check is a prescribed verification process through which an employer or other organisation subject to the applicable requirements establishes an individual’s permission to undertake relevant work in the UK. The prescribed methods and evidence requirements depend on the individual’s immigration status and the applicable legal framework. Changes effective from 1 October 2026 extended the prescribed checking framework to specified worker contracts and individual subcontractor arrangements. Right to work compliance is separate from sponsor licence authorisation, although failures can also have consequences for sponsor suitability.
Statutory Excuse	A statutory excuse is the legal protection against liability for a civil penalty for illegal working that may be established where the responsible organisation carries out the prescribed right to work checks in accordance with the applicable requirements. The statutory excuse depends on compliance with the relevant checking and record-keeping provisions, including follow-up requirements where applicable. Holding a sponsor licence does not automatically establish a statutory excuse. Following an ownership change or business transfer, the employer should establish whether existing right to work records remain sufficient and whether fresh checks or other action are required under the applicable framework.
Individual Subcontractor	An individual subcontractor is an individual engaged to provide services under a subcontracting arrangement rather than necessarily through a conventional contract of employment. The precise legal classification and applicable obligations depend on the terms and substance of the working arrangement. Following the changes effective from 1 October 2026, specified individual subcontractor arrangements fall within the expanded prescribed right to work checking framework. Employers and organisations using subcontracted labour should assess which arrangements are covered and identify responsibility for carrying out the required checks.
Civil Penalty for Illegal Working	A civil penalty for illegal working is a financial penalty that may be imposed under the applicable immigration legislation where an organisation is found liable for employing or engaging an individual in breach of the relevant illegal working provisions. The availability of a statutory excuse depends on whether the prescribed right to work requirements have been satisfied. For licensed sponsors, illegal working breaches and relevant civil penalties may also affect sponsor suitability and expose the organisation to Home Office compliance action. These risks should be considered during corporate acquisition due diligence and post-completion workforce compliance reviews.
Home Office Reporting Deadline	A Home Office reporting deadline is the period within which a licensed sponsor must notify the Home Office of a specified organisational or worker-related change. Under section C4 of the sponsor guidance, relevant ownership and corporate changes must be reported within no more than 20 working days. Certain transactions also require a new sponsor licence application within an applicable 20-working-day period. Some SMS change requests involve separate supporting evidence submission deadlines, including an applicable five-working-day period. Employers should identify and comply with each relevant obligation separately.
