Sponsor Licence Group Company Changes: Employer Guide

Sponsor Licence Group Company Changes: At a Glance

Group company changes can affect sponsor licence coverage, Home Office reporting and the immigration position of sponsored workers. The key question is whether the legal entity employing the worker is properly covered by the relevant sponsorship arrangements after the corporate change.

Common ownership does not automatically allow every company in a group to use the same sponsor licence. A parent, subsidiary or related company can only rely on a group licensing arrangement where it is eligible and properly included within the approved structure.

Changes in direct ownership can also affect an existing licence even where the licensed company remains the same legal entity. Internal restructurings, acquisitions, disposals and the introduction of new holding companies therefore need to be assessed by reference to the actual pre- and post-transaction ownership structure.

Where sponsored workers move between group companies, the receiving organisation needs appropriate sponsorship authority. Qualifying mergers, takeovers or transfers of undertakings can allow existing immigration permission to continue in specified circumstances, while an ordinary change of employer may require new sponsorship and updated immigration permission.

Relevant corporate changes can also trigger Home Office reporting and 20-working-day licence application requirements. Right to work responsibilities should be reviewed separately, particularly where the group uses central employment companies, worker arrangements or individual subcontractors.

This guide explains how group company changes affect UK sponsor licences, when subsidiaries can share a licence, how acquisitions and internal restructurings affect licence coverage, how sponsored workers can move between group companies and the reporting, licensing and right to work issues employers need to manage.

 

Section A: How Do Group Company Changes Affect a Sponsor Licence?

 

The sponsor licence position depends on the legal structure of the group and the effect of the proposed change. Employers need to identify the licence holder, the entities covered by that licence, the legal employer of each sponsored worker and any change in ownership or control.

A group may operate through several companies with shared management, branding, HR and payroll while those companies remain legally separate for sponsorship purposes. The commercial group structure therefore cannot be used as a substitute for checking the actual Home Office licensing arrangements.

 

1. Does Common Ownership Mean Group Companies Share a Sponsor Licence?

 

No. Common ownership or control does not automatically give every company in a corporate group authority to sponsor workers under the same licence.

The Home Office-approved structure may include eligible UK branches, subsidiaries or related entities, but those entities need to be properly covered by the licensing arrangements. Other group companies remain separate for sponsorship purposes unless the applicable requirements have been satisfied.

Employers should distinguish between:

 

• The licence holder: the organisation granted the sponsor licence.
• Entities covered by the licence: eligible branches, subsidiaries or related companies included within the approved structure.
• The legal employer: the company responsible for the worker’s employment relationship.
• The sponsoring organisation: the licensed organisation responsible for the worker’s sponsorship.
• The entity responsible for right to work compliance: the organisation with checking obligations under the applicable statutory regime.

 

These roles can sit with different organisations within the same group. Centralised HR or immigration administration does not alter the underlying legal and licensing position.

 

2. Which Group Company Changes Can Affect the Sponsor Licence?

 

The immigration consequences depend on what changes legally, not how the restructuring is described internally.

Relevant changes can include:

 

1. A change in the direct ownership or control of the licensed organisation.
2. A change higher in the corporate ownership chain.
3. The acquisition or disposal of a subsidiary.
4. The addition or removal of an entity from a group licence.
5. The creation of a new subsidiary or holding company.
6. The transfer of sponsored workers to another legal employer.
7. A merger, takeover or transfer of an undertaking.
8. Changes to employment, duties, work locations or workforce management arrangements.

 

Direct ownership changes require particular care. The Home Office corporate change guidance includes circumstances in which changing the immediate parent of a licensed company can require a new sponsor licence application even though the ultimate ownership of the group remains unchanged.

Changes higher in the ownership chain can produce a different outcome. Employers should therefore compare the complete corporate structure before and after the transaction and establish where ownership, control and employment responsibility actually move.

 

3. Why Do Group Restructurings Create Sponsor Licence Risk?

 

Group restructurings can create gaps between the corporate structure and the sponsorship arrangements if the immigration position is not reviewed before implementation.

A worker may become employed by a company that is not covered by the relevant licence. A newly acquired subsidiary may be treated as though it automatically falls within the buyer’s sponsorship arrangements. An internal ownership change may also trigger a fresh licence requirement even though the business continues operating as before.

Where sponsored workers move to another organisation as part of a qualifying merger, takeover or transfer of undertaking, the receiving organisation may need to hold the appropriate sponsor licence or submit a valid application or route extension within 20 working days. That requirement is separate from reporting the corporate change.

Worker-level immigration consequences also need to be assessed. Qualifying corporate transfers can allow sponsored workers to continue under existing immigration permission where the relevant conditions are met, while an ordinary move to another group employer may require a new Certificate of Sponsorship and updated immigration permission.

Right to work responsibilities should be reviewed separately, particularly where the restructuring changes the employing or engaging entity or introduces central employment and service company arrangements.

Section B: Can Companies in the Same Group Share a Sponsor Licence?

 

Companies within the same corporate group can, in certain circumstances, be covered by a single UK sponsor licence. However, the arrangement must comply with the Home Office rules governing branches, subsidiaries and related entities.

Common ownership alone does not establish that every group company can sponsor workers under the same licence. The relevant entities must be eligible for inclusion and covered by the approved licensing arrangements.

Section L5 of the Home Office’s Workers and Temporary Workers sponsor guidance, Part 1, recognises different licensing structures for organisations operating through multiple UK offices, branches, subsidiaries or related entities.

A corporate group may operate a single licence covering eligible entities, maintain separate licences for individual companies or adopt a combination of licensing arrangements.

The appropriate structure depends on the group’s legal organisation, operational requirements, sponsorship needs and capacity to maintain effective compliance oversight.

 

1. When can a single sponsor licence cover multiple group companies?

 

The Home Office permits eligible UK branches, subsidiaries and related entities to be included within a wider sponsor licensing arrangement where the applicable requirements are met.

For example, a UK parent company with several UK subsidiaries may be able to operate one sponsor licence covering the relevant entities rather than requiring each subsidiary to hold a separate licence.

However, the group must establish that the entities meet the requirements for inclusion and have been properly incorporated into the licensing structure.

The Home Office may request evidence of the relevant corporate relationship, including information demonstrating common ownership or control.

Depending on the circumstances, this may involve company registration details, ownership records, shareholding information or other corporate documents.

The existence of a parent-subsidiary relationship is relevant, but employers should not assume that a newly incorporated or acquired subsidiary is automatically covered by a licence granted before that entity joined the group.

Where the group wishes to add a subsidiary to an existing licence, the applicable Home Office process must be followed and any restrictions on adding entities considered.

 

2. What are the alternatives to a group-wide sponsor licence?

 

The Home Office recognises several approaches to licensing organisations with multiple UK branches or related entities.

 

Licensing structure	How it operates	Principal consideration
Single group licence	Eligible UK entities are included within one sponsor licence.	Centralised management, with compliance action potentially affecting all entities covered by the licence.
Separate company licences	Individual group entities hold their own sponsor licences.	Separate sponsorship responsibilities, management arrangements and compliance obligations.
Multiple grouped licences	Selected UK entities are covered by different licences within the wider corporate group.	Requires clear allocation of entities, workers and compliance responsibilities.

 

A single group licence can simplify sponsorship administration where recruitment and immigration compliance functions are centrally managed. It may reduce duplication and allow the group to maintain consistent systems and procedures.

However, this arrangement creates shared compliance exposure. Where the Home Office downgrades or revokes a licence covering multiple entities, the consequences can extend across the branches and subsidiaries included within that licence.

Separate licences can create clearer organisational boundaries, although each licence holder must satisfy the relevant sponsorship requirements and maintain its own compliance arrangements.

The Home Office may also investigate other licensed entities within a group where compliance concerns arise in one business. Separate licences should therefore not be regarded as complete protection against wider scrutiny.

 

3. Can a subsidiary use its parent’s sponsor licence?

 

A subsidiary may be able to sponsor workers under its parent’s sponsor licence where it is eligible and included within the approved licensing arrangements.

It cannot automatically use the parent’s licence merely because the parent owns its shares.

Before relying on an existing group licence, the employer should confirm:

 

• That the subsidiary is an eligible entity under the Home Office licensing rules.
• That it is included within the relevant licence arrangements.
• That the licence covers the immigration route under which workers will be sponsored.
• That the proposed employment arrangements satisfy the applicable sponsorship requirements.
• That the group has appropriate systems for monitoring and reporting changes affecting sponsored workers.

 

This assessment is particularly important where a subsidiary has recently been incorporated, acquired from another group or established through an internal restructuring.

If the subsidiary is not covered by the existing licence, the group must consider whether it can be added or whether separate licensing arrangements are required.

 

4. How does the licensing structure affect compliance responsibility?

 

A group-wide licence does not remove the need for effective sponsorship oversight across the individual businesses included within it.

Where several subsidiaries are covered by one licence, the sponsor must maintain sufficient control over sponsorship activity and ensure that the relevant duties are met throughout the licensed organisation.

For example, a central immigration team may manage the SMS while individual subsidiaries undertake recruitment, maintain employment records and supervise sponsored workers.

The group must establish procedures ensuring that changes to a worker’s duties, salary, employment status or work location are identified and communicated to those responsible for sponsor reporting.

Responsibility should also be clearly allocated where a restructuring changes the management of a subsidiary or transfers HR functions to a central service company.

The choice between one licence and several licences should therefore take account of the group’s compliance systems, management accountability and exposure to enforcement action.

Employer takeaway: A single sponsor licence can cover eligible UK group companies, but only where the Home Office requirements are satisfied and the entities are properly included. Common ownership is not sufficient, and the licensing structure should reflect the group’s ability to manage sponsorship compliance across its businesses.

Section C: What Happens When a Company Joins or Leaves a Corporate Group?

 

When a company joins or leaves a corporate group, the sponsor licence implications depend on the legal structure of the transaction, the identity of the licence holder, any changes to ownership or control and whether sponsored workers will remain employed by the same organisation.

An acquisition, disposal or internal transfer of shares does not necessarily have the same immigration consequences as a transfer of the business itself. Employers must distinguish between changes in corporate ownership and changes to the legal entity responsible for employing sponsored workers.

This distinction is important because a sponsor licence cannot simply be transferred from one legal organisation to another as a commercial asset. In addition, a change in the direct ownership of a licensed organisation can trigger the Home Office’s requirement for a fresh sponsor licence application even where the legal entity continues trading and its ultimate ownership remains unchanged.

A corporate transaction may therefore create a need for Home Office reporting, a new sponsor licence application, changes to the entities covered by an existing licence or revised sponsorship arrangements for affected workers.

These issues should be identified before the transaction takes effect.

 

1. When a company is acquired by an existing corporate group

 

An acquisition can take several forms, each with different sponsorship implications.

Where a group acquires the shares of an existing company, the acquired business may continue operating through the same legal entity, with the same employees, employment contracts, premises and management arrangements.

However, continuity of the business does not necessarily preserve the existing sponsor licence.

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. The organisation must obtain appropriate sponsorship authorisation where required.

This is a material distinction from ordinary changes to corporate information that can be addressed through an SMS notification.

For example, if Company A holds a sponsor licence and its shares are acquired by Company B, the acquisition may constitute a change in direct ownership requiring action under the Home Office’s corporate change rules, even though Company A remains the employer of its sponsored workers.

Where the acquired company does not hold a sponsor licence, the buyer must establish whether it can be included within an existing group licence or whether separate licensing arrangements are required before it sponsors workers.

An acquisition should therefore include a sponsorship due diligence exercise covering the target company’s existing immigration position and the proposed post-completion group structure.

Relevant enquiries include:

 

• Whether the target company holds a sponsor licence and its current rating.
• Whether any sponsored workers are employed by the target.
• Whether the acquisition changes direct ownership or control of a licensed organisation.
• Whether the target will continue operating as a separate legal entity.
• Whether the buyer intends to include the target within an existing group licence.
• Whether employees will transfer to another group company after completion.
• Whether the transaction triggers reporting, new licence application or worker sponsorship requirements.
• Whether the transaction timetable allows the required immigration action to be completed.

 

A buyer should not assume that acquiring a licensed company automatically provides uninterrupted sponsorship authority.

 

2. When a subsidiary is sold or leaves the group

 

The disposal of a subsidiary can create significant sponsor licence issues, particularly where the departing company is covered by a group-wide licence.

If a subsidiary leaves the corporate group, its relationship with the existing licence holder changes. The employer must assess whether the departing entity can continue to be covered by that licence and whether its sponsored workers require alternative sponsorship arrangements.

Where the subsidiary is included within a wider group licence rather than holding its own licence, the disposal may mean that it can no longer rely on the existing sponsorship structure.

The buyer and seller should therefore establish responsibility for any required licence applications, reporting and worker sponsorship arrangements before completion.

If the subsidiary itself holds a sponsor licence, the sale may also engage the Home Office’s rules on changes in direct ownership. The fact that the subsidiary remains the same legal employer does not automatically mean that its licence can continue following the transaction.

The parties must distinguish between:

 

• A sale of shares in a licensed subsidiary.
• A sale of the subsidiary’s business and assets.
• A transfer of sponsored workers to another legal employer.
• The departure of an entity previously included within a group-wide sponsor licence.

 

Each arrangement can produce different licensing and immigration consequences.

Where sponsored workers are affected, continuity of their permission to work must be considered before the transaction is implemented.

A contractual agreement that employees will transfer with the business does not, by itself, resolve the Home Office sponsorship requirements.

 

3. When a new subsidiary is incorporated

 

Establishing a new subsidiary does not automatically mean that it can sponsor overseas workers through an existing group licence.

A newly incorporated company is a separate legal entity. Even where it is wholly owned by a licensed parent company, the group must establish whether it is eligible for inclusion within the existing licence and complete any required process.

If the new subsidiary will not employ or sponsor overseas workers, an immediate sponsor licence application may not be necessary.

However, if the subsidiary intends to recruit sponsored workers or receive employees from another group company, the employer must establish the appropriate sponsorship arrangements before implementing the proposed employment structure, subject to any specific corporate transfer provisions that apply.

For example, a group may establish a new operating subsidiary to take responsibility for an existing business division. Although the business activities, workforce and management remain largely unchanged, employees may become employed by a different legal entity.

That change can have immigration consequences even where the group retains ultimate ownership of the business.

The employer should assess whether the new subsidiary can be added to an existing group licence, requires a separate licence or falls within the Home Office arrangements governing qualifying corporate transfers.

 

4. When a subsidiary moves between companies within the same group

 

Internal transfers of subsidiaries are common in corporate reorganisations.

A group may move the shares of a trading subsidiary from one holding company to another, introduce an intermediate holding company or consolidate several subsidiaries beneath a new parent.

Although the restructuring may leave ultimate ownership and day-to-day operations unchanged, it can still have significant sponsor licence consequences.

The Home Office’s corporate change guidance expressly addresses changes in direct ownership. Its examples include an internal group restructuring in which the direct parent of a licensed organisation changes while ultimate ownership remains the same.

In those circumstances, the Home Office requires the licensed organisation to make a fresh sponsor licence application.

Employers should therefore not assume that an internal reorganisation is exempt from the ownership-change rules simply because no shares have been sold to an external buyer.

The analysis must identify the actual legal transaction and determine whether the licensed organisation’s direct ownership has changed.

For example, if a licensed subsidiary is moved from one intermediate holding company to another within the same wider group, the change may engage the Home Office’s requirements notwithstanding continuity of the ultimate parent.

Changes higher up the ownership chain should also be assessed, but they should not automatically be treated as equivalent to a change in the direct ownership of the licence holder.

Where the existing legal employer remains unchanged, the employer must separately consider the licensing consequences of the ownership change and any reporting obligations.

Where the restructuring also transfers employees to another group company, the sponsored worker transfer rules must be considered in addition.

 

5. Sponsor licence dormancy and revocation following corporate changes

 

The Home Office’s treatment of an existing sponsor licence following a corporate transaction depends on the nature of the change and the applicable provisions.

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.

These outcomes should not be treated as interchangeable.

A dormant licence is no longer available for ordinary new sponsorship activity, but the Home Office may permit limited continued access to the Sponsor Management System for specified administrative purposes, including managing the records of workers affected by the corporate change.

Revocation involves withdrawal of the licence and the loss of sponsorship authority under that licence.

The appropriate outcome depends on the circumstances and the Home Office’s assessment.

Employers should not assume that an existing licence will remain active simply because a corporate transaction has been reported.

Similarly, a licence becoming dormant does not mean that the receiving employer is exempt from the requirement to hold appropriate sponsorship authority.

Where sponsored workers transfer to another organisation, the receiving employer must satisfy the relevant licensing and sponsorship conditions.

 

6. The 20-working-day licence application requirement

 

The Home Office applies specific application requirements where sponsored workers move to another organisation as part of relevant mergers, takeovers or transfers of undertakings.

Where the receiving organisation does not already hold the appropriate sponsor licence, the guidance provides for a valid sponsor licence application, or an application to extend the scope of an existing licence, to be made within 20 working days of the workers moving to that organisation.

This requirement is distinct from the obligation to report the corporate change.

Employers should therefore distinguish between:

 

1. Reporting the relevant corporate transaction to the Home Office.
2. Making any required sponsor licence application or application to extend an existing licence.
3. Ensuring the receiving organisation accepts responsibility for the transferred sponsored workers.
4. Complying with the relevant conditions governing continuation of the workers’ sponsorship and immigration permission.

 

The 20-working-day provision should not be treated as a general permission for an unlicensed organisation to recruit or sponsor new workers while an application is pending.

It applies in the specific circumstances addressed by the Home Office’s corporate transfer guidance.

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 assess the requirements before completion and incorporate them into the transaction timetable.

 

7. Why transaction timing matters

 

Sponsor licence issues should be identified before a company joins or leaves a corporate group.

A transaction may be commercially ready to complete while the required immigration arrangements remain unresolved. This can create difficulties where a new employer is expected to take responsibility for sponsored workers immediately after completion.

The parties should establish:

 

1. Which legal entity currently sponsors each affected worker.
2. Which entity will employ those workers after completion.
3. Whether the transaction changes direct ownership or control of an existing licence holder.
4. Whether the receiving employer already has appropriate sponsor licence coverage.
5. Whether a fresh licence application or extension of an existing licence is required.
6. Whether the relevant corporate transfer provisions permit sponsored workers to continue without making new immigration applications.
7. Which organisations must submit Home Office notifications and within what periods.
8. Whether any right to work checking obligations arise from the change in employing or engaging entity.
9. How the transaction timetable accommodates the relevant immigration requirements.

 

These matters should be incorporated into the transaction’s legal and operational planning rather than left to the HR team after completion.

Where a restructuring involves several legal steps, the immigration implications should be assessed at each stage and against the intended final structure.

Employer takeaway: A company joining or leaving a corporate group does not produce one universal sponsor licence outcome. Direct ownership changes can require a fresh licence application even where ultimate ownership remains unchanged. Employers must assess the legal transaction, licensing structure and sponsored workforce before implementing the change.

Section D: Does a Subsidiary Need Its Own Sponsor Licence?

 

A UK subsidiary does not always need a separate sponsor licence to employ sponsored workers. Under the Home Office’s licensing arrangements, eligible subsidiaries and related entities can be included within a single sponsor licence where the relevant requirements are met.

However, a subsidiary that is not covered by an existing licence cannot assume that it is authorised to sponsor workers simply because its parent company or another group business holds a licence.

The decision depends on the subsidiary’s corporate relationship with the licence holder, its proposed employment arrangements, the group’s existing licensing structure and any restrictions affecting the relevant entities.

Section L5 of the Home Office’s sponsor guidance recognises different licensing structures for organisations with multiple UK branches and related entities. For these purposes, the term branch can include eligible UK-based subsidiaries and related businesses.

The group must also consider whether changes in ownership or control affect an existing licence independently of the question of whether the subsidiary can be included within a wider licensing arrangement.

 

1. When can a subsidiary be included on an existing sponsor licence?

 

A subsidiary may be eligible for inclusion where the group can demonstrate the necessary relationship of common ownership or control and satisfy the other applicable sponsorship requirements.

The Home Office may require evidence establishing the corporate relationship between the licence holder and the subsidiary.

This can include company ownership records, shareholding information, group structure charts or other documents demonstrating the relevant control arrangements.

However, an application to include a subsidiary is not necessarily approved simply because the corporate connection can be established.

The Home Office also considers whether the entity meets the relevant requirements and whether any restrictions prevent its inclusion.

Section L5 of the sponsor guidance identifies circumstances in which a branch cannot be added to an existing licence, including certain situations involving previous sponsor licence enforcement action or the inability to offer eligible sponsored employment.

Employers should therefore establish both the corporate eligibility of the subsidiary and its suitability for inclusion within the licence.

 

2. When might a subsidiary need a separate licence?

 

A separate sponsor licence may be necessary where a subsidiary cannot be included within the group’s existing licensing arrangements but intends to sponsor workers.

It may also be a deliberate commercial and compliance choice.

For example, a large corporate group may operate several distinct business divisions, each with its own management team, workforce and compliance procedures.

The group may decide that separate licences provide clearer responsibility for sponsored workers and reduce the extent to which compliance problems in one division directly affect sponsorship across the other businesses.

However, separate licences do not guarantee complete insulation from Home Office scrutiny.

Where related entities hold individual licences and one licence is downgraded or revoked, the Home Office may investigate the other licensed entities within the group.

Each licence holder must also maintain its own compliance arrangements, satisfy the relevant eligibility requirements and ensure that sponsored workers are employed in accordance with the applicable immigration rules.

The decision should therefore reflect the group’s operational structure, compliance capability and risk exposure rather than merely the administrative convenience of holding fewer licences.

 

3. Can a newly acquired subsidiary be added to the group’s existing licence?

 

Potentially, but the acquisition itself does not establish that the subsidiary is covered by the buyer’s existing sponsor licence.

The buyer must assess whether the subsidiary meets the requirements for inclusion and whether the acquisition triggers separate obligations concerning the ownership or control of an existing licensed organisation.

Where the acquired subsidiary already holds a sponsor licence, the Home Office’s rules on mergers, takeovers and ownership changes must be considered before deciding how the post-acquisition sponsorship structure should operate.

In particular, a change in direct ownership can require a fresh sponsor licence application even where the acquired subsidiary remains the same legal employer.

The buyer should not assume that adding the subsidiary to another group licence automatically resolves every obligation arising from the change of ownership.

Where sponsored workers transfer between organisations, the group must also consider the relevant corporate transfer provisions and whether the receiving organisation holds appropriate sponsorship authority.

The appropriate solution may involve:

 

• A fresh sponsor licence application by the acquired organisation.
• An application to include an eligible subsidiary within an existing group licence.
• An application to extend the scope of an existing licence in circumstances permitted by the Home Office.
• Separate licensing arrangements for the acquired business.
• Worker-specific sponsorship and immigration action where required.

 

The correct approach depends on the legal structure of the transaction and the applicable Home Office requirements.

 

4. Can a subsidiary sponsor workers through an overseas parent company?

 

A UK subsidiary cannot rely solely on an overseas parent company’s corporate status as authority to sponsor workers in the UK.

The UK sponsorship arrangements must satisfy the requirements of the relevant immigration route.

Where a multinational group transfers workers between overseas and UK businesses, the Global Business Mobility routes may be relevant.

These routes have specific requirements concerning the relationship between the overseas business and the UK sponsor, as well as the eligibility of the worker and the proposed assignment.

Those requirements are distinct from the question of whether several UK group companies can be included within one sponsor licence.

An employer should therefore distinguish between:

 

• The overseas-to-UK corporate relationship relevant to an international assignment.
• The UK organisation authorised to sponsor the worker.
• The UK legal entity employing or engaging the worker.
• The entities covered by any group-wide UK sponsor licence.

 

A multinational corporate structure does not remove the need for appropriate UK sponsorship authority.

 

5. Should a corporate group use one licence or separate licences?

 

There is no universal answer. The appropriate licensing structure depends on the size of the group, the degree of operational integration and the ability of its management teams to meet sponsor duties.

A single group licence may be suitable where sponsorship is centrally controlled and the group maintains consistent HR systems, reporting procedures and immigration oversight.

Separate licences may be more appropriate where businesses operate independently, have different compliance management arrangements or wish to establish distinct responsibility for their sponsored workforces.

The compliance consequences are material.

Under the Home Office’s licensing arrangements, revocation or downgrading of a licence covering multiple UK branches can affect all the entities included within that licence.

Where separate licences are held, enforcement action against one licence does not automatically mean that every other group licence will receive the same action. However, the Home Office may investigate related licence holders where compliance concerns arise.

Employers should therefore consider:

 

• The number and nature of UK group entities requiring sponsorship authority.
• Whether sponsorship functions are genuinely centralised.
• The group’s ability to maintain consistent compliance systems.
• The level of operational independence between subsidiaries.
• The potential consequences of enforcement action affecting a shared licence.
• The administrative requirements associated with multiple licences.
• The likelihood of future acquisitions, disposals or internal reorganisations.

 

The chosen structure should support effective compliance as well as the group’s commercial and recruitment requirements.

 

6. Group company sponsorship decision matrix

 

The following matrix provides a practical starting point for assessing common corporate group scenarios. The precise requirements depend on the legal transaction, the entities involved and the applicable Home Office guidance.

 

Group company scenario	Principal sponsorship question	Action to assess
New UK subsidiary established	Will the subsidiary employ or sponsor overseas workers?	Confirm eligibility for inclusion in an existing licence or consider a separate application.
Existing subsidiary begins overseas recruitment	Is the subsidiary already covered by appropriate sponsorship arrangements?	Verify licence coverage before assigning sponsorship.
Group acquires an unlicensed company	Will the acquired company need to sponsor workers?	Assess inclusion within an existing group licence or separate licensing.
Group acquires a licensed company	Does the acquisition change direct ownership or control?	Apply the Home Office ownership-change rules, including any fresh licence application requirement.
Subsidiary changes immediate parent within the same group	Has the direct ownership of the licensed organisation changed?	Assess the requirement for a fresh licence even where ultimate ownership is unchanged.
Change occurs higher up the ownership chain	Does the change affect the licence holder’s direct ownership, control or reportable circumstances?	Assess the specific legal effect rather than assuming every ownership change has the same outcome.
Subsidiary is sold to another group	Can the departing company continue under its current licensing arrangements?	Review ownership-change rules, licence coverage and sponsored worker arrangements.
Business transfers under TUPE or similar provisions	Are sponsored workers moving to another employer under a qualifying transfer?	Assess receiving sponsor responsibilities, licence requirements, reporting and continuation of immigration permission.
Sponsored worker voluntarily moves to another group employer	Is the move an ordinary change of sponsor?	Determine whether a new Certificate of Sponsorship and updated immigration permission are required.
Group centralises employment through a service company	Which entity employs, sponsors and directs the workers?	Assess sponsorship eligibility, third-party working restrictions and right to work checking responsibilities.
Group changes HR or reporting arrangements	Have the licence holder, legal employer or relevant sponsor details changed?	Review reporting duties, sponsor governance and record accuracy.

 

The matrix demonstrates why employers should not treat all internal reorganisations alike.

Some changes principally affect the information maintained by the Home Office. Others can require a fresh sponsor licence application, changes to the licence’s coverage or new sponsorship arrangements for workers.

In particular, a change in direct ownership must be distinguished from a change in ultimate ownership, and a qualifying corporate transfer must be distinguished from an ordinary change of employer.

 

7. Reviewing the licensing structure after an acquisition or restructuring

 

Following a material corporate change, employers should verify that the sponsor licence structure accurately reflects the group’s new legal organisation.

This should include confirming the entities covered by each licence, identifying any new or departing subsidiaries and reviewing the sponsorship arrangements for affected workers.

The group should also assess whether its compliance management arrangements remain appropriate.

For example, an acquisition may significantly increase the number of sponsored workers managed by a central immigration team. Alternatively, a disposal may remove the subsidiary responsible for particular HR or compliance functions.

Where responsibility for sponsorship activity changes, the group should ensure that its Authorising Officer and authorised SMS users have appropriate oversight and access to the information needed to meet sponsor duties.

A post-transaction review should reconcile corporate records, sponsor licence details, employment arrangements and relevant Home Office notifications.

Employer takeaway: A subsidiary may be included within a group sponsor licence, but the Home Office requirements must be satisfied and coverage properly established. Acquisitions and internal ownership changes can also trigger fresh licensing obligations independently of the question of group licence eligibility.

Section E: Sponsor Licence Implications of Internal Group Restructuring

 

Internal group restructurings can affect sponsor licence arrangements even where there is no sale to an external buyer and the ultimate owners of the business remain unchanged.

Corporate groups frequently reorganise their legal structures for commercial, tax, financing or operational reasons. These changes may involve introducing new holding companies, consolidating subsidiaries, transferring business activities between entities or centralising employment arrangements.

Although the restructuring may be described as internal, the Home Office will be concerned with its legal and practical consequences for sponsorship.

The principal questions are whether the licensed organisation remains the same legal entity, whether its direct ownership or control has changed, whether the entities covered by the licence remain eligible and whether sponsored workers will continue to be employed under arrangements permitted by the sponsorship rules.

The employer must also consider whether the restructuring changes which organisation is responsible for right to work checks, particularly where individuals are employed or engaged through central service companies or other group working arrangements.

 

1. Changes to a corporate group’s holding company structure

 

A group may introduce a new holding company, remove an intermediate parent or transfer the shares of a subsidiary between existing group companies.

Such changes may leave the day-to-day operations of the sponsored business unaffected. Its employees, premises, management and trading activities may remain exactly as before.

However, the absence of operational change does not mean that there are no sponsor licence consequences.

The Home Office’s corporate change guidance distinguishes between different forms of ownership and organisational change. 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 requirement can apply even where the ultimate beneficial ownership of the business remains unchanged.

For example, a corporate group may hold a licensed trading subsidiary through Holding Company A. As part of an internal restructuring, the shares in the trading subsidiary are transferred to Holding Company B, which is owned by the same ultimate parent.

Although the trading subsidiary remains the same legal entity and continues employing the same workers, the change in its immediate parent can engage the Home Office’s direct ownership rules.

The group should therefore establish whether a new sponsor licence application is required rather than assuming that an internal share transfer is exempt from the sponsorship requirements.

Changes higher up the ownership chain should also be assessed, but employers should distinguish these from a change in the direct ownership of the licence holder.

Where the restructuring is implemented through several legal steps, each stage should be reviewed to identify the relevant ownership, reporting and licensing consequences.

 

2. Transferring business activities between subsidiaries

 

A more substantial sponsorship issue can arise where a group transfers business activities from one subsidiary to another.

For example, a group may decide to move its engineering division from Company A to Company B while retaining both businesses under the same parent company.

The commercial purpose may be straightforward, but the immigration consequences depend on how the transfer is implemented.

If workers remain employed by Company A and their sponsorship arrangements are unchanged, the group must assess whether changes to their duties, work locations or working arrangements require action.

If workers become employees of Company B, the group must establish whether Company B has appropriate sponsorship authority and whether the transfer falls within the Home Office provisions governing qualifying corporate transfers.

A transfer of business activities does not automatically transfer the sponsor licence or the immigration sponsorship of the workers involved.

Where the transaction involves a qualifying transfer under the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE), or another transfer recognised under the Home Office’s corporate change provisions, affected workers may be able to continue without making new immigration applications solely because their employment has transferred.

However, this depends on the applicable conditions being satisfied, including the receiving organisation’s licensing position, acceptance of responsibility for the sponsored workers and the workers continuing in the same sponsored occupation code, with no material change taking the role outside the existing sponsored employment.

Where the transfer does not fall within those provisions, an ordinary change of sponsoring employer may require a new Certificate of Sponsorship and an application to update the worker’s immigration permission.

The employer should therefore establish the legal basis of the transfer before deciding whether existing sponsorship arrangements can continue.

 

3. Consolidating subsidiaries into a single legal entity

 

Some restructurings involve combining several operating subsidiaries into one company.

This may be achieved through business transfers, corporate mergers, the dissolution of existing entities or the creation of a new operating company.

Where the consolidation changes the legal employer of sponsored workers, the group must assess whether the receiving organisation has appropriate sponsorship authority.

If the receiving company already holds a sponsor licence, the employer should establish whether that licence covers the relevant sponsorship activity and whether the transfer can be accommodated under the Home Office’s corporate change provisions.

If the receiving company does not hold an appropriate licence, the group must consider the specific application requirements.

Under the Home Office rules governing relevant mergers, takeovers and transfers of undertakings, a receiving organisation without the appropriate sponsor licence may be required to make a valid licence application, or apply to extend the scope of an existing licence, within 20 working days of the sponsored workers moving to it.

This is a specific corporate transfer provision and should not be treated as general permission for an unlicensed company to sponsor new workers while awaiting approval.

Where several licensed subsidiaries are combined, the group should prepare a worker-by-worker assessment identifying:

 

• The worker’s current legal employer and sponsoring organisation.
• The immigration route and relevant sponsorship details.
• The receiving legal employer.
• Whether the transfer falls within the Home Office’s corporate transfer provisions.
• Whether the receiving organisation holds appropriate sponsorship authority.
• Any new licence application or extension requirement.
• Any worker-specific reporting or immigration application requirement.
• The entity responsible for right to work checks following the transfer.

 

The group should also establish whether any existing licences will become dormant or be revoked following the restructuring.

These are distinct Home Office outcomes and should not be treated as interchangeable.

 

4. Centralising employment through a group service company

 

Corporate groups sometimes establish a central employment or service company to employ staff who work across different operating subsidiaries.

This arrangement may be intended to simplify payroll, employee benefits, workforce administration or the provision of shared services.

However, the use of a central employing entity can create particular issues under the sponsorship rules.

A sponsor must satisfy the Home Office requirements concerning the employment it sponsors, including responsibility for the worker, the nature of the work undertaken and compliance with the relevant immigration route.

The fact that a group service company is the contractual employer does not automatically establish that it can sponsor workers whose day-to-day activities are undertaken for other group entities.

Equally, centralised payroll or HR administration does not, by itself, mean that a sponsorship arrangement is prohibited.

The group must assess the actual working arrangements, including:

 

• Which legal entity employs the worker.
• Which organisation holds the relevant sponsor licence.
• Which entity directs and supervises the worker’s activities.
• The contractual relationships between the group companies.
• Whether the worker is performing a genuine role for the sponsoring organisation.
• Whether the arrangement involves the supply of labour to another organisation.
• Whether the proposed duties and working arrangements satisfy the relevant immigration route requirements.

 

Particular care is required where a sponsored worker would effectively be supplied to another organisation to undertake an ongoing role.

The Skilled Worker sponsorship rules restrict arrangements involving the hiring out of sponsored workers to third parties or their engagement to fill ongoing routine roles for third parties.

Employers should not assume that common ownership between group entities removes the need to consider these restrictions.

The distinction is between a genuine, permitted sponsorship arrangement and one in which the sponsor is effectively acting as a labour supplier.

 

5. Right to work responsibilities following the 1 October 2026 changes

 

Corporate groups must also consider the statutory right to work checking regime when reorganising employment and worker engagement arrangements.

Changes effective from 1 October 2026 extended the statutory right to work checking framework beyond traditional employment relationships to specified additional working arrangements.

The expanded regime is relevant to individuals engaged under worker contracts, certain individual subcontracting arrangements and specified online matching-service arrangements, subject to the statutory definitions and applicable requirements.

For corporate groups, this is particularly important where a central service company engages individuals who perform work for operating subsidiaries, or where a restructuring changes which legal entity contracts with or engages the worker.

The employer should establish which organisation has the statutory obligation to undertake the prescribed right to work check and retain the required evidence.

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.

This assessment must be distinguished from identifying the organisation responsible for immigration sponsorship.

The sponsor licence holder and the entity with statutory right to work checking responsibilities will not necessarily be the same organisation in every permitted working arrangement.

In addition, the Home Office’s sponsor record-keeping guidance requires sponsors to retain appropriate evidence of right to work checks for sponsored workers, including in circumstances where another organisation undertakes the check.

Employers should therefore review:

 

1. Which legal entity employs or engages the individual.
2. Whether the arrangement falls within the statutory right to work checking regime.
3. Which organisation is responsible for conducting the prescribed check.
4. Whether an existing check and any applicable continuity provisions are sufficient or a new check is required.
5. Whether time-limited permission requires a follow-up check.
6. Which organisation must retain evidence and for how long.
7. What additional evidence the sponsor must retain to satisfy its sponsorship duties.

 

A change in group structure does not automatically require every worker to undergo a new right to work check. The requirement depends on the legal and practical circumstances, including the identity of the employing or engaging organisation and the applicable checking rules.

Employers should avoid treating right to work checks as an administrative formality that can be addressed after the new employment arrangements have commenced.

 

6. Changes to trading names, business locations and reporting structures

 

Not every internal reorganisation involves a change in legal employer or direct ownership.

A group may change the trading name of a subsidiary, relocate a business division, alter management reporting lines or centralise its immigration compliance team without transferring employees to a different company.

Such changes may be less disruptive to existing sponsorship arrangements, but they can still affect the information that the Home Office requires sponsors to maintain or report.

For example, changes to the organisation’s trading details, premises, key personnel or relevant business circumstances may need to be reflected in the Sponsor Management System.

The employer should distinguish between changes that affect the validity or coverage of the licence and changes that principally affect the accuracy of the sponsor’s records.

Both matter, but they require different responses.

Where sponsorship responsibilities are centralised, the group should ensure that the Authorising Officer and authorised SMS users retain effective oversight of the licensed organisation and its sponsored workforce.

 

7. Managing sponsorship across a multi-stage restructuring

 

Complex group reorganisations may take place over several months and involve multiple legal entities.

An employer should avoid assessing each transaction in isolation where the intended end state involves a materially different employment or sponsorship structure.

A coordinated review should identify:

 

1. The current corporate structure and sponsor licence holders.
2. The entities covered by each licence.
3. The direct and ultimate ownership arrangements of licensed organisations.
4. The employing entity and immigration status of each sponsored worker.
5. The legal changes proposed at each stage.
6. The intended post-restructuring employer of each worker.
7. Any new licensing, reporting or immigration requirements.
8. Any right to work checking obligations arising from the revised arrangements.
9. Dependencies between the corporate transaction timetable and immigration requirements.
10. The arrangements for maintaining sponsorship compliance during the transition.

 

This assessment should be documented and updated where the restructuring plan changes.

Where the transaction involves a direct ownership change, the group should establish the relevant fresh licence application requirement. Where sponsored workers transfer between employers, the group should separately assess the Home Office’s corporate transfer provisions.

Following implementation, the employer should verify that the actual corporate and employment arrangements correspond with those assessed before the restructuring.

Employer takeaway: An internal group restructuring is not automatically exempt from sponsor licence requirements. Changes to direct ownership, the legal employer or the entities covered by a licence can trigger new applications, reporting obligations and worker-specific immigration requirements. The expanded right to work regime from 1 October 2026 adds a further consideration where the restructuring changes how individuals are employed or engaged.

Section F: Can Sponsored Workers Transfer Between Group Companies?

 

Sponsored workers may be able to move between companies within the same corporate group, but the immigration requirements depend on the entities involved and the legal basis of the transfer.

A move between two entities covered by the same sponsor licence is not necessarily treated in the same way as a transfer to a company holding a separate licence.

Employers must also distinguish between an ordinary change of employer, a transfer arising from a qualifying merger or transfer of an undertaking, a temporary assignment and a change in work location.

Common ownership does not give sponsored workers unrestricted permission to move between group employers.

The employer must establish whether the receiving organisation has appropriate sponsorship authority, whether the worker can continue under existing immigration permission and whether reporting or a new immigration application is required.

 

1. Transfers between entities covered by the same sponsor licence

 

Where two UK group entities are properly covered by the same sponsor licence, there may be scope for a sponsored worker to move between them without requiring an entirely new sponsorship arrangement.

However, this should not be treated as an automatic right.

The employer must consider the applicable immigration route, whether the worker’s sponsoring organisation remains the same for Home Office purposes and whether the move involves changes to employment that require reporting or a fresh immigration application.

For example, a group may have a single sponsor licence covering several UK subsidiaries. A worker employed by one subsidiary may be offered a role with another subsidiary covered by the same licence.

Before implementing the move, the sponsor should confirm that both entities are included in the licence, that the proposed role remains eligible and that the worker’s existing immigration permission permits the change.

Changes to occupation, duties, salary or other material employment conditions may create additional requirements independently of the group company transfer.

The employer must also consider whether the move constitutes a change of legal employer or falls within a recognised licence reorganisation or corporate transfer arrangement.

The fact that both companies are covered by one licence therefore resolves only part of the analysis.

 

2. Transfers to a group company holding a separate sponsor licence

 

A transfer to a group company holding its own separate sponsor licence requires closer consideration because the worker may be moving to a different sponsoring organisation.

Under the Skilled Worker route, a worker who changes sponsoring employer will ordinarily need a new Certificate of Sponsorship and a successful application to update their immigration permission before starting the new sponsored employment.

The existence of a corporate relationship between the original and receiving employers does not ordinarily remove this requirement.

However, the Home Office provides specific arrangements for certain corporate transfers, including qualifying mergers, takeovers and transfers of undertakings.

Where those provisions apply and the relevant conditions are satisfied, the position may differ from an ordinary voluntary change of employer.

The group should therefore establish whether the proposed move is:

 

• An ordinary voluntary transfer to another group employer.
• A transfer between entities covered by the same licence.
• A change arising from the reorganisation of an existing licence.
• A qualifying transfer of employment following a merger, takeover or transfer of an undertaking.
• A temporary assignment or secondment that does not involve a change of legal employer.

 

The correct classification determines the sponsorship and immigration action required.

 

3. Transfers arising from mergers, takeovers or TUPE

 

Where sponsored workers transfer to a new employer as part of a merger, takeover or qualifying transfer of an undertaking, the Home Office has specific rules governing the continuation of sponsorship.

These provisions recognise that employment may transfer by operation of law or under relevant corporate transfer arrangements without the worker voluntarily changing employer in the ordinary way.

Where the applicable conditions are satisfied, affected sponsored workers may be able to continue working without making new immigration applications solely because their employment has transferred.

However, this does not mean that sponsorship obligations disappear or that the receiving employer can operate without appropriate licensing arrangements.

The receiving organisation must meet the relevant Home Office requirements, including accepting responsibility for the transferred sponsored workers and holding or obtaining the appropriate sponsor licence.

Where the receiving organisation does not already hold an appropriate licence, the corporate transfer guidance can require a valid sponsor licence application, or an application to extend the scope of an existing licence, within 20 working days of the workers moving to it.

The original and receiving sponsors must also comply with the applicable reporting requirements.

Continuation of the worker’s existing immigration permission is subject to the relevant conditions. In particular, the worker must continue in the same sponsored occupation code, with no material change taking the role outside the existing sponsored employment.

The Home Office may make the former sponsor’s licence dormant following a qualifying corporate change, with limited SMS access retained for relevant administrative purposes.

That outcome must be distinguished from revocation of a licence.

Employers should not assume that every movement of workers between group companies qualifies for these arrangements.

An ordinary internal reassignment or voluntary move to a different group employer is not necessarily equivalent to a qualifying transfer of an undertaking.

 

4. Temporary assignments and secondments within a corporate group

 

A group may wish to assign a sponsored worker temporarily to another subsidiary while retaining the worker’s original employment contract.

The immigration implications depend on the substance of the arrangement.

Relevant considerations include whether the worker remains employed and sponsored by the original organisation, whether their duties and work location change and whether the arrangement complies with the requirements of the relevant immigration route.

The group must also consider the restrictions on supplying sponsored workers to third parties.

A secondment should not be assumed to be permissible simply because both entities have the same ultimate parent company.

Where the worker will perform services for another group entity, the sponsor should assess the contractual and operational arrangements to establish whether it remains responsible for the sponsored employment and whether the proposed activities are permitted.

The employer should distinguish between a genuine assignment consistent with the worker’s sponsorship and an arrangement in which the sponsoring organisation effectively supplies labour to another business.

The right to work position must also be assessed separately.

Following the expansion of the statutory right to work checking regime from 1 October 2026, the group should determine whether the receiving or engaging entity has checking obligations under the applicable rules, even where the original organisation remains responsible for sponsorship.

The analysis should address the legal relationship between the parties rather than assuming that the sponsor licence holder is automatically the only organisation with right to work responsibilities.

 

5. Changes to a sponsored worker’s role following a group transfer

 

Even where a corporate transfer can be accommodated within existing sponsorship arrangements, changes to the worker’s employment may create separate immigration requirements.

For example, the receiving company may propose a different role, revised duties, a new salary structure or a different work location.

The employer must consider whether the revised role remains in the same sponsored occupation code and whether any material change takes the role outside the existing sponsored employment.

Some changes may be reportable through the Sponsor Management System. Others may require a fresh Certificate of Sponsorship and an application to update immigration permission.

The employer should also consider whether the worker’s salary continues to satisfy the applicable requirements and whether any change in occupation or duties amounts to a change requiring a new immigration application.

A corporate transfer does not provide general permission to disregard the conditions attached to a worker’s immigration status.

The group should therefore assess the worker’s role before and after the transfer, rather than treating the immigration position as an administrative matter that automatically follows the employment contract.

 

6. What should employers check before transferring sponsored workers?

 

Before moving a sponsored worker between group companies, the employer should complete a structured assessment of the legal, sponsorship and right to work implications.

 

Question	Why it matters
Who is the current legal employer?	Identifies the existing employment relationship.
Which organisation currently sponsors the worker?	Establishes responsibility under the sponsor licence.
Is the receiving company covered by the same licence?	Helps determine whether existing sponsorship arrangements can continue.
Will the worker’s employment legally transfer?	Distinguishes a change of employer from a change in working arrangements.
Does the transfer arise from a qualifying corporate transaction?	May engage the Home Office’s specific merger, takeover or transfer of undertaking provisions.
Does the receiving organisation hold an appropriate sponsor licence?	Identifies whether new licensing arrangements or an extension application are required.
Will the worker’s duties, occupation or salary change?	May create additional sponsorship or immigration requirements.
Are organisational or worker reporting obligations triggered?	Ensures the Home Office receives the required notifications.
Is a new immigration application necessary?	Determines whether the worker can lawfully begin the proposed employment.
Which entity has statutory right to work checking responsibilities?	Identifies the organisation responsible for prescribed checks under the applicable regime.
What right to work evidence must the sponsor retain?	Ensures compliance with sponsor record-keeping requirements independently of the statutory checking regime.

 

The answers should be recorded before the transfer takes effect.

Where several sponsored workers are moving as part of a group restructuring, the employer should maintain a central schedule showing the immigration position and required action for each individual.

This is particularly important where workers hold different immigration permissions, are sponsored under different routes or will move to different receiving entities.

 

7. Avoiding gaps in lawful sponsorship and right to work compliance

 

One of the principal risks in an intercompany transfer is that the employment change takes effect before the necessary sponsorship arrangements have been identified or established.

For example, a group may transfer employees to a newly incorporated subsidiary on a specified date, assuming that the parent company’s existing sponsor licence is sufficient.

If the subsidiary is not covered by the licence and the relevant corporate transfer provisions do not apply, the group may encounter serious difficulties with the workers’ immigration position.

Equally, where the transfer qualifies under the Home Office’s corporate change provisions, the employer must comply with the applicable reporting and licensing requirements, including any 20-working-day application requirement.

The group must also determine whether the change in employing or engaging entity creates new statutory right to work checking obligations.

Existing sponsorship records should not automatically be treated as sufficient evidence that every entity involved has complied with its own right to work responsibilities.

Employers should therefore align the timing of employment transfers with:

 

• Any required sponsor licence applications or extensions.
• Relevant Home Office corporate change notifications.
• Any new Certificates of Sponsorship or immigration applications.
• Confirmation that the receiving organisation can lawfully employ the affected workers.
• Applicable statutory right to work checks and evidence retention.
• Updates to sponsorship records and internal compliance systems.

 

Where the position is uncertain, the transfer should be assessed before implementation rather than relying on retrospective administrative corrections.

Employer takeaway: Sponsored workers cannot move freely between group companies simply because those companies share an owner. The employer must determine whether the receiving entity has appropriate sponsorship authority, whether a qualifying corporate transfer exception applies, whether the worker requires updated immigration permission and which organisation is responsible for right to work compliance.

Section G: Reporting Group Company Changes to the Home Office

 

Licensed sponsors must report relevant changes to their organisation and sponsored workforce to the Home Office. Where a corporate group undergoes an acquisition, disposal, internal restructuring or change in ownership, the employer must establish which reporting obligations apply and which organisation is responsible for complying with them.

Reporting requirements can arise even where the restructuring takes place entirely within an existing corporate group and does not involve an external buyer.

However, reporting a change does not necessarily mean that the existing sponsor licence can continue. Certain changes in direct ownership can require a fresh sponsor licence application, while qualifying corporate transfers may create separate licensing and worker sponsorship requirements.

Employers must therefore distinguish between reporting obligations, sponsor licence application requirements and the immigration arrangements affecting individual sponsored workers.

The relevant framework is set out in the Home Office’s Workers and Temporary Workers sponsor guidance, particularly Part 3 on sponsor duties and compliance and its provisions concerning mergers, takeovers and changes of ownership.

 

1. Which group company changes must be reported?

 

The Home Office requires sponsors to report specified changes to their organisation, business circumstances and sponsored workers.

In the context of corporate groups, reportable changes can include:

 

• Changes in the ownership or control of the licensed organisation.
• Mergers, takeovers and relevant transfers of undertakings.
• Changes affecting the legal entity responsible for sponsored workers.
• Changes to the branches, subsidiaries or related entities covered by the licence.
• Changes to the organisation’s legal name, trading details or relevant business circumstances.
• Changes to the sponsor’s business address or relevant operating locations.
• Changes involving key personnel responsible for the licence.
• Relevant changes to sponsored workers’ employment, duties or work arrangements.
• The cessation of trading or other circumstances affecting the organisation’s ability to fulfil its sponsorship duties.

 

The precise reporting requirements depend on the nature of the change and the applicable Home Office provisions.

For example, a change in a subsidiary’s trading name may principally require an organisational notification, whereas a change in the direct ownership of a licensed company may engage the Home Office’s rules requiring a fresh licence application.

Similarly, transferring a business and its employees to another group company can create obligations for both the transferring and receiving organisations.

Employers should therefore identify each reportable event rather than treating the entire restructuring as a single notification.

 

2. How are corporate changes reported through the Sponsor Management System?

 

The Sponsor Management System (SMS) is the Home Office’s online platform for managing sponsor licences and reporting relevant changes.

Authorised users can submit notifications and requests concerning the sponsor’s organisation, licensing arrangements and sponsored workers, subject to the permissions available to them.

Where a group company change occurs, the employer should establish the appropriate SMS reporting process and the information required to support the notification.

This may include details of the transaction, the legal entities involved, the effective date of the change and the position of any affected sponsored workers.

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.

Relevant evidence may include:

 

• Pre- and post-transaction corporate structure charts.
• Company registration and ownership records.
• Share transfer or acquisition documentation.
• Evidence of changes to direct ownership or control.
• Business transfer agreements or relevant TUPE documentation.
• Details of the entities employing sponsored workers before and after the change.
• Information concerning the proposed sponsor licence arrangements.

 

Submitting an SMS notification does not itself establish that a transaction complies with the sponsor licensing rules.

Where the Home Office requires a fresh licence application or an application to extend the scope of an existing licence, that requirement must be addressed separately.

 

3. Reporting changes in ownership or control

 

Changes in ownership or control require particular attention because they can affect the continuation of an existing sponsor licence.

The Home Office’s corporate change provisions distinguish between different ownership arrangements, including changes to the direct ownership of a licensed organisation.

Where the relevant direct ownership provisions apply, the sponsor may be required to make a fresh sponsor licence application rather than simply update its ownership details through the SMS.

This can apply even where the business continues trading under the same name, employs the same workers and remains under the same ultimate beneficial ownership.

For example, an internal restructuring that transfers the shares of a licensed subsidiary from one immediate parent company to another may engage the fresh licence application requirement.

Employers should therefore establish:

 

1. The ownership structure of the licence holder before the transaction.
2. The ownership structure following completion.
3. Whether the direct owner of the licensed organisation has changed.
4. Whether any other change in control or corporate circumstances is relevant.
5. Whether the existing licence can continue under the applicable Home Office rules.
6. Whether a fresh sponsor licence application is required.
7. What notifications and supporting evidence must be submitted.

 

Changes higher up the ownership chain should also be assessed, but should not automatically be treated as having identical consequences to a change in direct ownership.

The employer must apply the Home Office requirements to the actual legal structure of the transaction. 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.

 

4. Reporting changes to subsidiaries and entities covered by a licence

 

Where a sponsor licence covers several UK subsidiaries or related entities, changes to the composition of the group can affect the licence’s approved coverage.

For example, a group may acquire a new subsidiary, dispose of an existing subsidiary or transfer a business into a newly incorporated company.

The sponsor should establish whether the relevant entity is already covered by the licence and whether the change requires an application, notification or adjustment to the licensing arrangements.

A newly acquired or incorporated subsidiary should not be treated as automatically included merely because it is now under common ownership with the licence holder.

Equally, where a subsidiary leaves the group, the employer must assess whether it can continue to rely on the former group’s licence and what alternative sponsorship arrangements may be required.

The Home Office’s rules governing the inclusion of branches, subsidiaries and related entities must be considered alongside any ownership-change requirements.

Where the restructuring involves a change to the direct ownership of the licensed organisation itself, the employer must address that issue separately from the question of adding or removing group entities.

 

5. Reporting sponsored worker changes following a restructuring

 

Corporate restructurings can also trigger worker-specific sponsor reporting obligations.

For example, sponsored workers may transfer to another legal employer, change work locations, take on different duties or cease employment with the original sponsoring organisation.

The sponsor must determine whether these changes are reportable and whether they affect the worker’s existing immigration permission.

Under the general sponsor reporting framework, many specified changes affecting sponsored workers must be reported within 10 working days.

However, employers must distinguish those general worker reporting requirements from the specific provisions governing mergers, takeovers and qualifying transfers of undertakings.

Where a corporate transfer falls within the Home Office’s special arrangements, both the transferring and receiving organisations may have obligations concerning the affected workers.

The receiving sponsor must also establish whether the workers can continue under their existing immigration permission or require new sponsorship and immigration applications.

A corporate transfer should not be treated as an ordinary worker reporting event without considering the specific Home Office rules.

Right to work checking obligations must also be addressed separately. A sponsorship notification does not itself establish a statutory excuse against a civil penalty for illegal working.

Where a restructuring changes the legal employer or another entity responsible for engaging an individual, the organisation must assess the applicable right to work checking requirements, including the expanded regime effective from 1 October 2026.

 

6. What are the reporting and application deadlines?

 

Different Home Office deadlines can apply to the same corporate restructuring.

Employers should not assume that one notification satisfies all obligations or that every corporate change is subject to the same deadline.

 

Requirement	General timing	Employer consideration
Specified organisational changes	Generally within 20 working days, subject to the applicable sponsor guidance.	Identify the reportable event and the organisation responsible for notification.
Relevant mergers, takeovers and corporate transfers	Specific 20-working-day reporting requirements under the corporate change provisions.	Assess the obligations of the transferring and receiving organisations.
Receiving organisation requiring a sponsor licence following a qualifying corporate transfer	A valid application, or application to extend an existing licence’s scope, may be required within 20 working days of the sponsored workers moving to it.	This is an application requirement, not merely an SMS notification.
Specified sponsored worker changes	Generally within 10 working days under the ordinary worker reporting framework.	Consider whether specific corporate transfer provisions apply instead of, or alongside, the general requirements.
Right to work checks	Timing depends on the applicable statutory checking requirements and the individual’s circumstances.	Establish whether a prescribed check is required before the relevant employment or engagement begins and whether follow-up checks are necessary.

 

The exact deadline should be verified against the current Home Office guidance and the circumstances of the transaction.

In particular, the 20-working-day licence application requirement for relevant receiving organisations should not be confused with the 20-working-day period for reporting specified organisational changes.

These are distinct obligations and failure to comply with either can create serious sponsorship consequences.

Employers should maintain a transaction-specific action register recording the relevant event, deadline, responsible organisation, required submission and confirmation of completion.

 

7. Who is responsible for reporting changes within a corporate group?

 

Responsibility for Home Office reporting rests with the relevant licensed sponsor, even where immigration administration is managed centrally.

A corporate group may operate a shared HR or immigration team responsible for preparing SMS notifications across several businesses.

However, centralised administration does not remove the individual sponsor’s responsibility to comply with the conditions of its licence.

Where several group companies hold separate licences, each organisation must assess and fulfil its own reporting obligations.

In a corporate transfer, the original and receiving sponsors may have separate duties arising from the same transaction.

For example, the transferring sponsor may need to report that workers have moved to another organisation, while the receiving sponsor must address its own licensing and reporting requirements.

The group should therefore allocate responsibility for each action rather than assuming that one notification submitted by the parent company covers every licensed entity.

The Authorising Officer must maintain appropriate oversight of sponsorship compliance, supported by authorised SMS users and the relevant operational teams.

Where the restructuring changes the individuals responsible for managing a licence, the employer should also assess the applicable key personnel requirements and notifications.

 

8. Record keeping following group company changes

 

Employers should maintain a clear documentary record of the sponsorship decisions and actions taken during a corporate restructuring.

This is important both for ongoing compliance and in the event of a Home Office audit or investigation.

Relevant records may include:

 

• Corporate structure charts before and after the transaction.
• Documents evidencing ownership and control.
• Transaction completion documents and relevant transfer agreements.
• Records identifying the legal employer of sponsored workers.
• Copies or confirmations of SMS notifications.
• Evidence of sponsor licence applications or applications to extend licence coverage.
• Correspondence with the Home Office concerning the corporate change.
• Worker transfer schedules and immigration assessments.
• Relevant Certificates of Sponsorship and immigration permission records.
• Evidence of prescribed right to work checks and any follow-up checks.
• Records demonstrating compliance with sponsor duties under Appendix D.

 

The group should distinguish between the retention requirements imposed by the sponsorship rules and those applying under the statutory right to work checking regime.

Appendix D of the Home Office sponsor guidance sets out the documents sponsors must retain and the applicable record-keeping periods.

Separate requirements govern the retention of evidence used to establish a statutory excuse under the right to work scheme.

Other legal obligations, including employment, corporate and data protection requirements, may also affect how long particular records should be retained.

Employers should therefore avoid applying one universal retention period to every document generated during a restructuring.

Records should be accurate, accessible and retained for the applicable period, with appropriate arrangements for transferring responsibility where the relevant employing or sponsoring entity changes.

Employer takeaway: Group company changes can trigger several distinct Home Office obligations. Employers must identify the correct reporting requirements, any fresh licence application or licence extension requirement, the responsibilities of transferring and receiving sponsors, and the separate right to work checking obligations affecting the workforce.

Section H: Sponsor Licence Risks When Group Structures Change

 

Changes to corporate group structures can expose employers to significant immigration compliance risks where the sponsorship consequences are not identified before implementation.

These risks are not limited to acquisitions involving external buyers. Internal reorganisations, changes to holding company arrangements, transfers of employees between subsidiaries and the establishment of central service companies can all affect sponsorship compliance.

The Home Office expects licensed sponsors to maintain accurate records, report relevant changes and comply with the conditions of their licences.

Where a corporate transaction affects the legal entity employing sponsored workers or the ownership of a licensed organisation, the employer must establish whether existing sponsorship authority remains valid and whether new arrangements are required.

The consequences of non-compliance can include licence downgrading, suspension or revocation, disruption to sponsored workers’ immigration permission and exposure to illegal working enforcement action.

 

1. Sponsored workers employed by an entity without appropriate licence coverage

 

One of the principal risks arises where a corporate group assumes that all subsidiaries can use a sponsor licence held by the parent company or another group business.

Common ownership does not automatically provide sponsorship authority.

If a subsidiary is not covered by the relevant licence, the group must establish appropriate arrangements before relying on that entity to sponsor workers, subject to any specific corporate transfer provisions that apply.

For example, a group may establish a new operating subsidiary and transfer employees to it without reviewing whether the new entity is covered by the existing licence.

Where sponsored workers are affected, the group may discover that the legal employer has changed but the sponsorship arrangements have not been properly addressed.

This can create problems concerning the validity of sponsorship, the worker’s immigration permission and the sponsor’s compliance with Home Office requirements.

Employers should therefore maintain an accurate register of the entities covered by each sponsor licence and verify coverage whenever the group structure changes.

 

2. Assuming that a sponsor licence transfers with an acquired business

 

A sponsor licence is not a commercial asset that can automatically be transferred from one organisation to another.

Where a business is acquired, merged or transferred, the employer must assess the Home Office rules governing the relevant corporate transaction.

In particular, 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, even where the licensed company remains the same legal entity and continues trading.

Where a business and its employees transfer to another legal organisation, the receiving employer must establish whether it holds or must obtain appropriate sponsorship authority.

Depending on the circumstances, the existing licence may become dormant or be revoked.

A dormant licence and a revoked licence have different consequences and should not be treated as equivalent.

The employer must also consider whether affected sponsored workers can continue under the Home Office’s corporate transfer provisions or require new sponsorship and immigration applications.

A buyer should therefore assess sponsorship arrangements as part of transaction due diligence rather than assuming that the target’s existing licence will remain available after completion.

 

3. Failing to identify or report changes in direct ownership

 

Internal corporate restructurings can create a particular risk where the group assumes that unchanged ultimate ownership means there has been no relevant change for sponsorship purposes.

Under C4.5, where there is a relevant change in direct ownership, the existing licence will be revoked or, where sponsored workers have transferred under the relevant arrangements, made dormant.

This can apply where the immediate parent company changes within the same wider group.

Employers should therefore distinguish between direct ownership, ultimate ownership and changes in management or operational reporting arrangements.

Where the relevant direct ownership rules apply, an SMS notification alone may not satisfy the Home Office requirements.

The group should establish whether a fresh licence application is required and ensure that any reporting obligations are met within the applicable period.

Failure to identify the licensing consequences can affect the organisation’s ability to continue sponsoring workers.

 

4. Transferring sponsored workers without the correct immigration arrangements

 

Moving sponsored workers between group companies can create immigration risks where the transfer changes the legal employer or sponsoring organisation.

An ordinary move to another group employer may require a new Certificate of Sponsorship and an application to update the worker’s immigration permission.

However, certain qualifying mergers, takeovers and transfers of undertakings are subject to specific Home Office provisions that may permit affected workers to continue without making new immigration applications solely because their employment has transferred.

The employer must establish whether those provisions apply and whether their conditions are satisfied.

In relevant cases, the receiving organisation may be required to make a valid sponsor licence application, or apply to extend the scope of an existing licence, within 20 working days of the workers moving to it.

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 assess each transfer by reference to its legal basis rather than assuming that all intra-group movements are treated alike.

 

5. Inadequate compliance oversight across multiple subsidiaries

 

A corporate group may centralise immigration administration while allowing individual subsidiaries to manage recruitment, employment records and day-to-day supervision.

This can be an effective arrangement, but it requires clear allocation of responsibility.

Where operational teams fail to communicate changes affecting sponsored workers, the sponsor may miss reportable events or fail to maintain the records required by the Home Office.

Examples include:

 

• A subsidiary changing a sponsored worker’s duties without informing the immigration team.
• A group company transferring an employee to another legal employer without checking sponsorship requirements.
• A business division relocating sponsored workers without reviewing reporting obligations.
• A newly acquired subsidiary being treated as covered by a group licence without verification.
• Changes to key personnel or organisational details not being reported.
• Responsibility for sponsor compliance becoming unclear following a restructuring.

 

These risks increase where the group has several sponsor licences, operates across multiple locations or has recently completed an acquisition.

Employers should maintain documented procedures ensuring that corporate and workforce changes are reviewed for immigration implications before implementation.

 

6. Group-wide exposure to sponsor licence enforcement

 

The licensing structure can affect the consequences of Home Office enforcement action.

Where a single sponsor licence covers several UK branches or subsidiaries, downgrading or revocation can affect all entities included within that licence.

This means that compliance failures arising in one part of the group can create wider consequences for the organisation’s ability to sponsor workers.

Separate licences can establish distinct licensing responsibilities, but they do not guarantee that enforcement concerns will remain confined to one group company.

Where related entities hold separate licences and the Home Office identifies serious compliance concerns in one organisation, it may investigate other licensed entities within the group.

Employers should therefore consider group-wide compliance governance even where sponsorship authority is divided between separate legal entities.

Regular internal audits, consistent reporting procedures and clear accountability can help identify risks before they lead to enforcement action.

 

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

 

Group restructurings can also create illegal working risks where employers fail to establish which legal entity is responsible for right to work checks.

The statutory right to work checking regime was expanded from 1 October 2026 to cover specified working arrangements beyond traditional employment contracts.

This is particularly relevant where corporate groups engage individuals through central service companies, worker contracts, individual subcontracting arrangements or other structures involving more than one legal entity.

Where a restructuring changes the organisation employing or engaging an individual, the group must assess whether the new arrangements create or alter statutory checking obligations.

These obligations should not be confused with the sponsor’s separate duties under the immigration sponsorship framework.

A sponsor may be required to retain evidence of a right to work check under Appendix D even where another organisation is responsible for conducting the prescribed statutory check.

Employers should therefore establish:

 

• Which organisation employs or engages the individual.
• Whether the arrangement falls within the statutory checking regime.
• Which organisation is responsible for conducting the prescribed check.
• Whether a new check is required or an existing check remains sufficient under the applicable rules.
• Whether a follow-up check is required because the individual has time-limited permission.
• What evidence must be retained by the employer or engaging entity.
• What additional records must be maintained by the sponsoring organisation.

 

A failure to undertake a prescribed check where required may leave an employer without a statutory excuse against a civil penalty for illegal working.

Separate consequences may arise where the organisation also breaches its sponsor licence duties.

Employers should not assume that a valid sponsor licence or Certificate of Sponsorship automatically establishes compliance with the statutory right to work checking requirements.

 

8. Inconsistent corporate, employment and sponsorship records

 

Following a restructuring, discrepancies can arise between the group’s corporate records, HR systems and the information held by the Home Office.

For example, Companies House records may show that a subsidiary has changed ownership while the sponsor’s internal licence register still reflects the former group structure.

Employment contracts may identify a new legal employer while sponsorship records continue to refer to the original organisation.

Alternatively, a group may have completed the necessary Home Office notifications but failed to update its internal worker records or right to work checking procedures.

Such inconsistencies can create difficulties during a Home Office compliance visit or investigation.

The employer should therefore reconcile:

 

• Corporate ownership and group structure records.
• The legal entities covered by each sponsor licence.
• Employment contracts and HR records.
• Sponsored worker information and Certificates of Sponsorship.
• Relevant SMS notifications and Home Office correspondence.
• Right to work checking evidence.
• Internal responsibility for sponsorship and workforce compliance.

 

A post-completion compliance review can help identify discrepancies and establish whether corrective action is required.

 

9. Inadequate immigration due diligence before acquisitions

 

Corporate acquisitions can expose a buyer to existing sponsor compliance problems within the target business.

A company may hold a sponsor licence but have deficiencies in its reporting, record keeping, right to work procedures or management of sponsored workers.

These issues can become more difficult to address after completion, particularly where the buyer intends to integrate the target’s workforce into its existing operations.

Immigration due diligence should therefore consider:

 

1. Whether the target holds a sponsor licence and its current status.
2. Whether the licence covers the relevant legal entities and immigration routes.
3. The number and immigration status of sponsored workers.
4. Whether sponsorship records are complete and accurate.
5. Whether reportable changes have been submitted within the required periods.
6. Whether the target has been subject to Home Office compliance action.
7. Whether there are outstanding sponsor licence applications or notifications.
8. Whether right to work checks have been conducted and documented appropriately.
9. Whether the proposed acquisition changes direct ownership or control.
10. Whether the post-acquisition structure requires fresh licensing or worker sponsorship arrangements.

 

Where deficiencies are identified, the buyer should determine how they affect the transaction, the proposed integration and the group’s future sponsorship arrangements.

Immigration issues should be incorporated into the wider transaction risk assessment rather than treated as routine HR administration.

 

10. Practical steps to reduce sponsor licence risks

 

Employers can reduce the risks associated with group company changes by incorporating immigration compliance into corporate planning and governance.

Recommended measures include:

 

1. Maintain an accurate licence register: identify every licence holder, the entities covered by each licence and the relevant sponsorship routes.
2. Review ownership changes before implementation: establish whether direct ownership or control changes trigger fresh licensing requirements.
3. Assess sponsored workers individually: identify their current and proposed employers, immigration permissions and any transfer requirements.
4. Confirm receiving employer sponsorship authority: establish whether the receiving entity holds the appropriate licence or must make an application.
5. Distinguish reporting from applications: maintain separate action items for SMS notifications, new licence applications and worker immigration requirements.
6. Review right to work responsibilities: identify the organisation responsible for prescribed checks and sponsor record keeping under the applicable regime.
7. Allocate compliance responsibility: ensure that corporate, HR and immigration teams understand their respective duties.
8. Maintain transaction records: retain evidence of the restructuring, immigration assessments and Home Office submissions.
9. Conduct a post-completion review: confirm that the actual corporate and employment arrangements correspond with the approved sponsorship structure.
10. Audit group-wide compliance: review the effectiveness of reporting, record keeping and workforce monitoring across all relevant entities.

 

These measures are particularly important for groups undertaking frequent acquisitions, disposals or internal reorganisations.

The employer should also ensure that its corporate advisers and transaction teams identify immigration dependencies early enough to influence the proposed implementation timetable.

Employer takeaway: Sponsor licence risks arise where corporate structures change faster than the organisation’s immigration compliance arrangements. Employers should assess direct ownership, licence coverage, worker transfers, reporting duties and right to work responsibilities before implementing a restructuring, then verify that the new arrangements are properly reflected in their records and procedures.

Section I: Group Company Sponsor Licence Change Checklist

 

Employers planning an acquisition, disposal or internal group restructuring should assess the sponsor licence implications before implementing the corporate changes.

The review should cover the group’s existing licensing arrangements, the legal entities affected, changes in direct ownership or control, the position of sponsored workers and the Home Office reporting and application requirements.

It should also identify which organisations have statutory right to work checking obligations following the changes, taking account of the expanded regime effective from 1 October 2026.

The following checklist provides a practical framework for identifying and managing the principal issues.

 

1. Establish the existing sponsor licence structure

 

The first step is to identify which companies within the group hold sponsor licences and which entities are covered by those licences.

A corporate group may operate through a single licence covering several eligible UK entities, separate licences for individual subsidiaries or a combination of arrangements.

The employer should establish:

 

• The legal name and company registration number of each licence holder.
• The sponsor licence reference and current licence rating.
• The UK branches, subsidiaries and related entities covered by each licence.
• The immigration routes under which each organisation is authorised to sponsor workers.
• The Authorising Officer, Key Contact and authorised SMS users responsible for each licence.
• The arrangements for managing sponsorship compliance across the group.
• Any existing Home Office restrictions, outstanding applications or compliance action.

 

This information should be reconciled with the group’s current corporate structure.

Where subsidiaries have been incorporated, acquired, sold or reorganised since a licence was granted, the employer should verify that the licensing arrangements remain accurate.

 

2. Identify the proposed corporate changes

 

The employer should prepare a clear description of the restructuring, including the legal steps involved and the proposed implementation dates.

This should identify whether the transaction involves:

 

• The acquisition or disposal of a subsidiary.
• A change in direct ownership of a licensed organisation.
• A change higher up the corporate ownership chain.
• The introduction or removal of a holding company.
• The transfer of shares between group companies.
• The incorporation of a new subsidiary.
• The consolidation or dissolution of existing companies.
• The transfer of a business or undertaking.
• The movement of employees between legal entities.
• The centralisation of employment, payroll or workforce engagement arrangements.

 

Pre- and post-transaction structure charts can help identify changes that might otherwise be overlooked.

The assessment should focus on the legal effect of the transaction rather than its commercial description.

For example, an internal reorganisation may involve a change in direct ownership even where the ultimate shareholders remain unchanged.

Where the Home Office’s direct ownership provisions apply, a fresh sponsor licence application may be required notwithstanding continuity of the licensed company’s business and workforce.

 

3. Identify affected sponsored workers

 

The employer should prepare a schedule of sponsored workers who may be affected by the proposed changes.

The schedule should record the current employing entity, sponsoring organisation, immigration route, occupation, relevant employment conditions and immigration permission details.

It should also identify whether each worker will remain employed by the same legal entity after the restructuring.

Where employment will transfer, the employer should establish the receiving organisation and whether it has the necessary sponsorship authority.

Additional consideration may be required where the restructuring changes the worker’s occupation, duties, salary or work location.

The employer should also determine whether the transfer qualifies under the Home Office provisions for mergers, takeovers or transfers of undertakings.

Those provisions may allow affected workers to continue without making new immigration applications solely because their employment has transferred, 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.

An ordinary change of sponsoring employer may require new sponsorship and updated immigration permission.

The purpose of this exercise is to determine the requirements for each worker rather than assuming that one solution will apply to the entire workforce.

 

4. Determine whether existing licences can continue

 

The employer should assess whether the proposed corporate changes affect the validity, ownership or coverage of existing sponsor licences.

This includes considering whether:

 

1. The licence-holding organisation will remain the same legal entity.
2. Its direct ownership or control will change.
3. Any change in the wider ownership chain creates reporting or licensing obligations.
4. An entity will join or leave the corporate group.
5. A subsidiary needs to be added to or removed from an existing licence.
6. A new employing entity requires its own sponsor licence.
7. The transaction engages the Home Office provisions for mergers, takeovers or transfers of undertakings.
8. An existing licence may become dormant or be revoked.

 

Employers should not assume that an existing licence can continue simply because the business retains the same trading name, management or ultimate beneficial ownership.

Where the consequences are uncertain, the group should resolve the licensing position before implementing employment transfers or relying on the proposed arrangements.

 

5. Establish reporting and application requirements

 

The employer should identify all relevant Home Office reporting obligations and any applications required to establish or maintain lawful sponsorship.

A restructuring may require organisational notifications, worker-specific reports, changes to the entities covered by a licence or a fresh sponsor licence application.

In relevant mergers, takeovers and transfers of undertakings, a receiving organisation without the appropriate sponsor licence must make the required valid licence application, or application to extend the scope of an existing licence, within 20 working days of the sponsored workers moving to it. If the application is not made within that period, or 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.

This requirement must be distinguished from the separate obligation to report the corporate transaction.

The applicable deadlines should be confirmed against the relevant Home Office guidance.

Where several licensed entities are involved, responsibility for each notification or application should be allocated to the appropriate sponsor.

The employer should maintain a central action register showing the requirement, responsible organisation, deadline, submission date and outcome.

 

6. Align immigration requirements with the transaction timetable

 

Sponsor licence requirements should be incorporated into the restructuring’s implementation plan.

This is particularly important where sponsored workers will transfer to a new employer or where the receiving organisation requires new licensing arrangements.

The employer should establish whether any immigration applications, licensing steps or right to work checks must be completed before the proposed employment changes take effect.

Where the Home Office’s qualifying corporate transfer provisions apply, the employer must identify the relevant conditions and deadlines, including any post-transfer licence application requirement.

Those provisions should not be treated as general permission for an unlicensed organisation to recruit or sponsor new workers.

The corporate transaction timetable should allow sufficient time to address the relevant requirements.

A commercial completion date does not override the conditions attached to a worker’s immigration permission.

 

7. Review right to work checking responsibilities

 

The employer should assess whether the restructuring changes which organisation is responsible for conducting prescribed right to work checks.

This is particularly important following the expansion of the statutory right to work checking regime from 1 October 2026.

The changes extend the framework to specified working arrangements beyond traditional employment contracts, including certain worker contracts, individual subcontracting arrangements and online matching-service arrangements.

Where a corporate group centralises employment or engages individuals through a service company, the legal relationships should be reviewed to establish which entity has the relevant statutory checking obligations.

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 group should confirm:

 

• Which organisation employs or engages each affected individual.
• Whether the arrangement falls within the statutory right to work checking regime.
• Which organisation is responsible for the prescribed check.
• Whether a new check is required or an existing check remains sufficient under the applicable rules.
• Whether follow-up checks are required for individuals with time-limited permission.
• Which entity must retain evidence of the check.
• What additional records the sponsoring organisation must maintain under Appendix D.

 

The statutory right to work checking regime and the sponsor’s record-keeping duties are separate obligations.

The sponsor should not assume that its licence or the worker’s Certificate of Sponsorship automatically establishes a statutory excuse against an illegal working civil penalty.

Equally, a restructuring does not automatically require every worker to undergo a new right to work check. The requirement depends on the applicable rules and the circumstances of the employment or engagement.

 

8. Update records and compliance procedures after completion

 

Following implementation, the employer should verify that the group’s sponsorship records accurately reflect its new structure.

This may include updating corporate structure charts, internal licence registers, HR records, employment documentation and relevant SMS information.

The group should also review whether changes to management responsibilities or business operations require adjustments to its sponsor compliance procedures.

Where sponsorship functions have been centralised or transferred between teams, the employer should ensure that the responsible personnel have sufficient oversight of all sponsored workers.

Right to work checking procedures should also be reviewed where the restructuring changes the employing or engaging entity.

Records must be retained in accordance with the applicable requirements. Employers should distinguish between sponsorship record-keeping obligations under Appendix D, statutory right to work evidence-retention requirements and any other relevant legal obligations.

A post-completion compliance review can help identify discrepancies between the intended restructuring and the arrangements actually implemented.

 

9. Employer checklist summary

 

Check	Required action
Licence holders identified	Confirm every sponsor licence holder, current status and relevant immigration routes.
Group entities mapped	Identify subsidiaries and branches covered by each licence.
Corporate changes documented	Prepare pre- and post-restructuring structure charts.
Direct ownership assessed	Identify changes requiring action under the Home Office ownership-change rules.
Sponsored workers identified	Prepare a worker-level immigration schedule.
Receiving employers confirmed	Establish who will employ affected workers after the change.
Licence coverage verified	Determine whether new or amended licensing arrangements are needed.
Corporate transfer provisions assessed	Establish whether TUPE or another qualifying transfer arrangement applies.
Worker permissions reviewed	Identify new sponsorship or immigration application requirements.
Reporting requirements established	Confirm applicable notifications, evidence and deadlines.
Licence applications identified	Distinguish fresh licence applications and scope extensions from SMS reporting.
Right to work responsibilities verified	Identify the entity responsible for prescribed checks and evidence retention.

Section K: Conclusion

 

Group company changes can affect UK sponsor licences even where a restructuring takes place entirely within an existing corporate group.

The critical distinction is between corporate ownership and sponsorship authority. A parent company, subsidiary or related business cannot assume that common ownership automatically entitles it to employ sponsored workers under another group company’s licence.

Employers must establish which legal entities are covered by their existing licences, whether the proposed transaction changes direct ownership or control and whether sponsored workers will remain employed by the same organisation.

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, even where ultimate ownership and day-to-day business operations remain unchanged.

Where a company joins or leaves a group, the consequences may include changes to licence coverage, Home Office reporting, new licensing arrangements or revised sponsorship requirements for affected workers.

Internal restructurings can also create immigration obligations where employment transfers between subsidiaries or a new group service company becomes responsible for the workforce.

Qualifying mergers, takeovers and transfers of undertakings may allow sponsored workers to continue without new immigration applications solely because their employment has transferred, but the receiving organisation must satisfy the applicable sponsorship and licensing requirements.

The expansion of the statutory right to work checking regime from 1 October 2026 adds a further consideration where corporate groups reorganise employment or worker engagement arrangements.

The most effective approach is to assess these issues before the corporate changes take effect. This allows the group to coordinate its transaction timetable, immigration applications, reporting obligations and right to work procedures while maintaining appropriate oversight of sponsored workers.

For employers with complex group structures, regular reviews of sponsor licence coverage and corporate ownership can help ensure that sponsorship arrangements remain consistent with the organisation’s actual legal and operational structure.

Section L: Sponsor Licence Group Company Changes FAQs

 

Can two companies in the same group use one sponsor licence?

Yes. Eligible UK group companies may be covered by a single sponsor licence under the Home Office’s arrangements for branches and related entities. However, common ownership does not automatically provide sponsorship authority. The relevant companies must be included within the approved licence structure and meet the applicable requirements.

 

Does a wholly owned subsidiary need its own sponsor licence?

Not necessarily. A wholly owned UK subsidiary may be eligible for inclusion within its parent’s sponsor licence. If it is not covered by that licence and intends to sponsor workers, separate licensing arrangements or an approved change to the existing licence may be necessary.

 

What happens to a sponsor licence when a company is acquired?

The consequences depend on the legal structure of the acquisition and whether it changes ownership or control of the licensed organisation. The Home Office has specific rules for mergers, takeovers and ownership changes. In particular, a change in direct ownership can require a fresh sponsor licence application even where the acquired company remains the same legal employer.

 

Can a newly acquired subsidiary use the buyer’s existing sponsor licence?

Not automatically. The buyer must establish whether the subsidiary is eligible to be included within its existing licence and complete any required process. The acquisition may also create separate obligations concerning the target company’s existing sponsor licence and sponsored workers.

 

What happens when a subsidiary leaves a corporate group?

A departing subsidiary may no longer be eligible for coverage under the former group’s sponsor licence. The parties should assess the subsidiary’s future licensing arrangements and the position of any sponsored workers before the disposal is completed. Where the subsidiary holds its own licence, the transaction may also engage the Home Office’s direct ownership provisions.

 

Does an internal group restructuring require a new sponsor licence?

Not every internal restructuring requires a new licence. However, changes in the direct ownership of a licensed organisation can trigger a fresh licence application requirement even where ultimate ownership remains unchanged. The answer depends on the legal steps involved, the licensed organisation and whether sponsored workers move between employers.

 

Can sponsored workers transfer between subsidiaries?

Potentially, but the requirements depend on the entities involved and the nature of the transfer. A move between entities covered by one licence may be treated differently from a change to a separately licensed employer. New sponsorship or immigration permission may be required unless the applicable rules permit the existing arrangements to continue.

 

Does TUPE allow sponsored workers to transfer without a new visa?

The Home Office provides specific arrangements for qualifying transfers of undertakings, mergers and takeovers. Where the relevant conditions are satisfied, workers may not need a new immigration application solely because their employment transfers. However, 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.

 

Does a change of holding company affect a sponsor licence?

It can. Introducing a new holding company or moving a subsidiary between immediate parent companies may change the direct ownership of the licensed organisation. The Home Office’s guidance includes circumstances in which a fresh sponsor licence application is required despite unchanged ultimate ownership. The legal effect of the restructuring must therefore be assessed.

 

Do changes to group companies need to be reported to the Home Office?

Relevant changes may need to be reported through the Sponsor Management System. These can include changes to ownership, organisational structure, branches or sponsored workers. The applicable requirements and deadlines depend on the nature of the change. Reporting must also be distinguished from any separate requirement to make a fresh sponsor licence application.

 

Can a group service company sponsor employees working for subsidiaries?

The position depends on the actual employment and working arrangements. The sponsor must meet the requirements of the relevant immigration route, including restrictions on supplying sponsored workers to third parties. A central employment contract, shared payroll arrangement or common ownership does not automatically establish that the arrangement is permissible.

 

Is it better for a corporate group to hold one sponsor licence or several?

Both approaches can be appropriate. A single licence can simplify administration but may expose all covered entities to the consequences of licence enforcement. Separate licences can create clearer organisational responsibility, although each licensed company must meet its own compliance obligations. The appropriate structure depends on the group’s operations, future restructuring plans and compliance capability.

 

How do the 1 October 2026 right to work changes affect group company restructurings?

The changes expand the statutory right to work checking regime to specified working arrangements beyond traditional employment contracts. This is relevant where groups use central service companies, worker contracts, individual subcontracting arrangements or other structures involving multiple entities.

Employers should establish which organisation has statutory checking obligations following a restructuring and whether prescribed checks or follow-up checks are required. These duties are separate from the sponsor’s immigration reporting and record-keeping obligations. A group restructuring does not automatically require every worker to undergo a new right to work check.
