Holiday Entitlement When Leaving a Job

Holiday entitlement is a common source of dispute when employees leave a job. Employers must calculate accrued leave accurately to avoid unlawful deduction claims, payroll errors and compliance issues under the Working Time Regulations 1998. Getting the calculation right is also an important part of delivering a fair and transparent offboarding process that reflects well on the organisation.

What this article is about:
This guide explains how employers and HR professionals should work out holiday entitlement when an employee leaves a job. It covers statutory rules, contractual variations, pro-rata calculations, treatment of bank holidays, final pay adjustments, deductions for overtaken leave and best practice when communicating entitlements to departing employees. The aim is to give employers a clear, legally accurate framework for assessing what an employee is owed on their final day of employment and how to make any payments or deductions lawfully.

When an employee leaves part-way through the leave year, their entitlement must be recalculated up to the termination date. This involves assessing statutory annual leave, any contractual additions, the method of accrual used by the organisation and the employee’s “normal remuneration” for holiday pay purposes. Employers must also handle situations where the employee has taken more holiday than they accrued, ensuring any recovery from final pay is lawful and supported by contractual terms. It is also important to recognise that statutory holiday continues to accrue during sickness absence, and the first four weeks of statutory leave can be carried over where the worker has been unable to take it due to long-term sickness or maternity leave. COVID-related temporary carry-over rules ended in March 2024 and no longer apply.

The introduction sets the context for the detailed sections that follow, helping employers understand not only the legal obligations but also the practical steps needed to manage final holiday calculations effectively.

Section A: Legal framework for holiday entitlement at termination

This section sets out the legal rules that determine how much holiday an employee is entitled to when their employment ends. Employers must apply the Working Time Regulations 1998 (WTR), the employee’s contract of employment and any relevant case law when calculating entitlement. Understanding this framework is critical before attempting any numerical calculation, as entitlement depends not only on statutory rights but also on the organisation’s contractual arrangements.

1. Statutory rights under the Working Time Regulations 1998

Under the WTR, almost all UK workers are entitled to a minimum of 5.6 weeks’ paid annual leave per leave year. This incorporates both the 4 weeks derived from EU law and the additional 1.6 weeks under domestic UK legislation. When an employee leaves part-way through the leave year, they are entitled to be paid for any statutory annual leave accrued up to the termination date that has not been taken. Regulation 14 of the WTR sets out the statutory method for calculating the payment in lieu of this untaken statutory holiday, and employers must ensure that, at termination, they are at least meeting this statutory calculation even if they use an internal accrual method during employment.

Statutory leave accrues proportionally throughout the leave year. For fixed-hour workers, employers typically use a monthly or calendar-day accrual method to calculate entitlement, provided the method never results in less than the employee’s statutory entitlement. For leavers, the Regulation 14 approach and accompanying statutory accrual table provide the benchmark, and any internal method should be checked against that benchmark.

For irregular hours or part-year workers, an accrual based on hours worked and the average “working time” is now required following the 2024 reforms to annual leave calculation for these categories. The reforms introduced a statutory mechanism that permits a percentage accrual based on 12.07% of hours worked in each pay period for irregular hours and part-year workers, but this approach is not mandatory for all workers. It applies only where the worker falls within the statutory definitions and the employer opts to use the percentage-based method for leave years beginning on or after 1 April 2024, with transitional rules applying where leave years straddle that date. Employers must therefore confirm whether a worker falls into one of these categories and ensure that the chosen method aligns with the new statutory framework.

Workers continue to accrue statutory holiday during periods of sickness absence and during maternity and other family leave. Where a worker is unable to take the first four weeks of statutory leave because of long-term sickness or maternity leave, they must be allowed to carry that leave over into the next leave year. COVID-related temporary carry-over provisions, which allowed broader carry-over, ended in March 2024 and no longer apply.

Importantly, statutory annual leave cannot be replaced by a payment in lieu while the employment relationship continues, except where the worker is unable to take leave due to maternity or long-term sickness. However, once employment ends, employers must pay in lieu of untaken statutory leave in accordance with Regulation 14, ensuring that the worker receives a payment equivalent to what they would have earned had they taken the leave during employment.

2. Contractual holiday provisions

Many employers offer holiday entitlement above the statutory minimum. Contractual entitlement may include additional days, enhanced bank holiday arrangements or rounding rules that differ from the statutory calculation. When an employee leaves, both statutory and contractual entitlements must be reviewed.

There is no freestanding statutory right to paid bank holidays. Whether bank holidays are paid and whether they accrue depends entirely on the contract. If the contract provides, for example, “5.6 weeks’ holiday including bank holidays”, bank holidays form part of the overall entitlement and are subject to the same accrual rules. If the contract provides “5.6 weeks’ holiday plus 8 paid bank holidays”, the bank holidays are an additional contractual benefit and will generally accrue proportionately for starters and leavers unless the contract clearly states otherwise.

If the contract provides a higher entitlement, the employer must calculate accrued leave based on the total contractual amount unless the contract explicitly states that enhanced leave does not accrue proportionately for starters and leavers. Any contractual limitation must be clearly drafted to be enforceable; ambiguous clauses often result in entitlement being interpreted in the employee’s favour.

Employers should also ensure their holiday policies and staff handbooks align with contractual provisions. A mismatch between the contract and handbook can create uncertainty when calculating a leaver’s entitlement, increasing the risk of disputes. Where garden leave is used, statutory holiday will continue to accrue throughout the garden leave period, and whether any enhanced contractual holiday accrues will depend on the wording of the contract and associated policies.

3. When payment in lieu is legally permitted

Payment in lieu of holiday (PILOH) is lawful only when employment has ended or when narrow statutory exceptions apply. While employers cannot pay workers instead of allowing them to take statutory annual leave during employment, they must make a payment in lieu for any accrued but untaken statutory holiday at termination. Regulation 14 requires that this payment is calculated by reference to the worker’s entitlement and the proportion of the leave year worked, so that the worker receives no less than they would have received had they taken the leave during employment.

This payment must be based on the employee’s “normal remuneration”, reflecting case law that holiday pay should mirror regular pay, including elements such as commission, regular overtime and allowances where these form part of normal earnings. For workers with variable pay, this will link into the 52-week reference period rules, using paid weeks only, which are discussed later in the article.

Employers must also consider whether contractual holiday beyond the statutory minimum is payable on termination. Some contracts allow for payment only for accrued statutory leave, with contractual leave excluded unless taken before the termination date. This must be expressly stated to avoid ambiguity. Where the contract is silent or unclear, a tribunal is likely to interpret any uncertainty in the employee’s favour, and employers may find themselves paying both statutory and contractual holiday in lieu.

Clear contractual drafting ensures employers can apply PILOH correctly without breaching the WTR or facing claims for underpayment. Employers should also distinguish carefully between payment in lieu of notice (PILON) and payment in lieu of holiday, as these are separate concepts governed by different rules. For holiday pay, the governing provisions are the WTR and Regulation 14, whereas notice pay is governed primarily by the Employment Rights Act 1996 and the contract of employment.

Section B: How to calculate accrued holiday at the leaving date

This section explains how employers should calculate the precise amount of holiday an employee has accrued up to their final day of employment. The calculation must follow statutory rules and any contractual provisions that alter entitlement, rounding or accrual method. Errors at this stage are one of the most common causes of disputes about final pay, making it important for employers to adopt a clear, consistent and legally compliant approach.

1. Pro-rata accrual formula for starters and leavers

When an employee leaves part-way through the leave year, their annual leave entitlement must be pro-rated to reflect the proportion of the year they have worked. For statutory annual leave, Regulation 14 of the Working Time Regulations 1998 provides the legal basis for determining how much statutory leave accrues up to the termination date. Employers may use internal methods such as monthly or calendar-day accrual during employment, provided these methods never result in less than the employee’s statutory entitlement. However, at termination, the Regulation 14 calculation is the benchmark and must not be undercut.

The monthly accrual method typically uses the formula:
full annual entitlement ÷ 12 × number of months worked.
Where employment ends mid-month, a calendar-day method may be used for greater precision. Employers should document the method used in contracts or policies to ensure consistency and reduce the likelihood of disagreement.

For irregular hours or part-year workers, the 2024 reforms introduced a statutory framework allowing a percentage-based accrual of 12.07% of hours worked in each pay period. This method applies only to irregular hours and part-year workers as defined in the legislation and only for leave years beginning on or after 1 April 2024. For leave years straddling that date, transitional rules apply. Employers should confirm whether the individual falls within the statutory definitions and ensure their chosen method complies with the revised legislation.

Statutory holiday continues to accrue during sickness absence, maternity leave and other protected forms of leave. The first four weeks of statutory leave can be carried over where the worker has been prevented from taking it due to sickness or maternity. These rules should be factored into the accrual calculation for leavers whose absence spans the leave year.

2. Treatment of bank holidays and contractual additional days

Holiday entitlement often includes bank holidays, either within the 5.6-week statutory entitlement or as an additional contractual benefit. There is no statutory right to paid bank holidays. How they are treated in final holiday calculations depends entirely on the wording of the contract.

If bank holidays are included within the employee’s total annual entitlement (for example, “5.6 weeks including bank holidays”), the holiday will accrue proportionately, and any bank holidays already taken must be accounted for in the calculation. Where the contract provides “5.6 weeks plus bank holidays”, the bank holidays are an additional contractual allowance and will accrue proportionately unless the contract expressly excludes such accrual. Employers should ensure that any exclusion is unambiguous to avoid disputes.

When bank holidays fall after an employee’s leaving date, the employee is not entitled to them unless their contract specifically provides a fixed entitlement irrespective of the leaving date. Conversely, if the employee has taken bank holidays in excess of their accrued entitlement, this may give rise to overtaken leave, which may be subject to recovery from final pay if the employer has the contractual authority to make the deduction.

Contractual additional days, whether framed as annual leave or bank holidays, must be pro-rated unless clearly stated otherwise. Employers should review their contracts and staff handbooks to ensure they align and provide clarity during the termination process.

3. Calculating payment for statutory annual leave

Once the amount of accrued leave is determined, employers must calculate how much the employee should be paid for it. Holiday pay must reflect the employee’s “normal remuneration”, following case law such as Lock v British Gas and Bear Scotland, which requires that holiday pay mirrors the pay the worker normally receives. This may include commission, regular overtime, allowances and other payments that form part of normal earnings.

For employees with variable earnings, the statutory 52-week reference period must be used. Employers must use 52 paid weeks, excluding any week in which the worker received no pay. If the reference period does not contain 52 paid weeks, employers must extend the period backwards to capture the necessary number of paid weeks, up to a maximum of 104 weeks. This ensures that holiday pay for leavers with variable earnings accurately reflects average remuneration.

For irregular hours or part-year workers, the new post-2024 rules apply, including the statutory percentage-based accrual mechanism where the employer has opted to use it. When calculating holiday pay for these workers, employers must ensure the payment reflects the worker’s average earnings and complies with the statutory framework.

Section B has provided a practical framework for calculating accrued holiday up to the employee’s leaving date. Employers must identify the correct accrual method, treat bank holidays appropriately and calculate holiday pay using normal remuneration principles. Applying the statutory rules and contractual terms accurately ensures fair and legally compliant final pay.

Section C: Final pay scenarios employers must manage

This section examines the practical scenarios employers face when finalising holiday entitlement at termination. The legal risks usually arise not from the calculation itself but from how unused or overtaken leave is handled in the employee’s final pay. Employers must ensure all payments and deductions comply with the Working Time Regulations 1998, the Employment Rights Act 1996, the National Minimum Wage framework and the employee’s contract of employment.

1. When the employee has unused accrued leave

If an employee has accrued more holiday than they have taken by their final working day, the employer must make a payment in lieu of this unused leave. This applies to statutory annual leave and, unless the contract states otherwise, contractual leave. Regulation 14 of the Working Time Regulations requires the calculation to ensure the worker receives no less than they would have earned had they taken the leave during employment.

Payment must reflect the employee’s normal remuneration, ensuring they receive a fair reflection of their typical earnings. Payroll teams should ensure that holiday pay is itemised correctly on the employee’s final payslip, clearly marked as payment in lieu of holiday so that the record aligns with statutory and contractual requirements.

Timing also matters. Holiday pay should be included in the employee’s final salary payment rather than delayed. Late payment can lead to disputes or potential unlawful deduction claims. Employers should also ensure that where the employee has variable earnings, the 52-week paid reference period has been applied correctly to avoid underpayment.

Employers should keep clear records demonstrating how the accrual and payment were calculated. This provides transparency and reduces the likelihood of challenge.

2. When the employee has overtaken holiday

A frequent issue arises when an employee has taken more holiday than they have accrued by their leaving date. In this situation, employers may recover the overpayment through a deduction from final salary, but only where there is clear written authority to do so.

The Employment Rights Act 1996 restricts deductions from wages unless:

• the deduction is required or authorised by statute
• the contract of employment expressly allows recovery of overtaken holiday
• the employee has provided prior written agreement

Without a clear contractual clause or signed agreement, any deduction will be treated as an unlawful deduction of wages. Employers must therefore ensure their contracts contain clear entitlement and deduction provisions.

Employers must also consider the interaction with the National Minimum Wage. A deduction for overtaken holiday cannot reduce the worker’s pay for the relevant pay reference period below the applicable minimum wage rate. While deductions for overpaid holiday are not normally treated as deductions “for the employer’s own use or benefit”, employers should still check compliance with minimum wage rules to avoid any risk of breach.

It is good practice to calculate the overtaken leave as early as possible in the notice period and to notify the employee in writing. This reduces the chance of shock or disagreement when the final payslip is issued.

3. Interaction with notice periods, garden leave and PILON

Holiday entitlement interacts with the termination process in several ways, and employers need to understand what they may and may not do during the notice period.

Requiring an employee to take holiday during notice:
Employers can require an employee to take statutory holiday during their notice period, provided they give the correct notice (at least twice the length of the leave to be taken). Contractual provisions may provide different rules. This can reduce the amount of holiday payable on termination, but the requirement must be applied lawfully and reasonably.

Garden leave:
An employee on garden leave remains employed and continues to accrue statutory holiday. Whether contractual holiday accrues will depend on the terms of the contract. Employers must still calculate any outstanding leave when the employment relationship ends, even if the employee has not been at work. The fact that the employee is not attending work does not affect statutory accrual.

Payment in lieu of notice (PILON):
Where an employer ends employment with a PILON clause, the contract terminates immediately and no further leave accrues beyond that date. If the employer does not have a PILON clause but still pays in lieu, the payment may be treated as damages for wrongful dismissal, meaning the contract technically continues for the statutory or contractual notice period. This distinction affects holiday accrual, since the employee may accrue additional statutory holiday during the notional notice period. Most employers include a PILON clause to avoid this complexity.

Employers should be careful not to confuse PILON with payment in lieu of holiday. These are distinct concepts with different legal rules and must be itemised separately in final pay documentation.

Section C has addressed the key scenarios that arise when an employee leaves with unused or overtaken leave. Employers must pay in lieu of any accrued but untaken holiday, ensure lawful deductions for overtaken leave and understand how notice, garden leave and PILON affect entitlement. Managing these issues correctly is central to compliant and dispute-free final pay.

Section D: HR processes and documentation

This section focuses on the practical HR and administrative steps employers should take to ensure final holiday entitlement is calculated, recorded and communicated correctly. Clear documentation and consistent processes are essential to avoid disputes, demonstrate compliance and support accurate payroll delivery.

1. Policies and employment contracts

Holiday calculation rules should be clearly set out in employment contracts and supported by an accessible holiday policy or staff handbook. Employers should ensure contracts contain:

• the total annual entitlement (statutory and contractual)
• the leave year dates
• the accrual method for starters and leavers
• provisions for bank holidays
• a clause permitting deductions for overtaken holiday

Where employers offer enhanced contractual leave, they should specify whether this leave accrues proportionally for starters and leavers. Without clear drafting, the default assumption is that all leave accrues proportionately. Ambiguity increases the risk of disputes at termination. Employers should also ensure their policies clarify whether contractual holiday accrues during periods such as garden leave, as statutory holiday will accrue but contractual holiday may not, depending on the wording.

Reviewing contract templates periodically helps ensure they remain compliant with changes in legislation, including the 2024 reforms affecting irregular hours and part-year workers. Employers who have not updated their documents since the reforms should do so to ensure the statutory definitions and permitted accrual methods are correctly reflected.

2. Payroll and record-keeping

Accurate records are the foundation of lawful holiday calculations. Employers must keep detailed data on:

• annual leave entitlement
• leave taken
• leave accrued
• working patterns
• variable pay elements used for holiday pay calculations

Where variable pay is relevant, payroll must maintain the 52-week reference data required to calculate average earnings for statutory holiday pay. Only paid weeks should be included in the reference period, and employers may need to look back up to 104 weeks to find 52 paid weeks. Records should be retained in line with statutory retention periods and easily accessible if a query arises.

HR and payroll should work together to produce a clear calculation breakdown for each leaver. This ensures transparency and enables the organisation to address any subsequent challenge with confidence.

3. Communicating entitlement to leavers

Clear communication helps prevent disagreements about holiday entitlement and final pay. Employers should:

• notify the employee of their accrued leave balance at the start of the notice period
• confirm whether the employee is required to take leave during notice
• explain whether any deduction will be applied for overtaken holiday
• include a full calculation in the final pay explanation or termination letter

Providing this information early reduces the likelihood of disputes arising on receipt of the final payslip. A well-structured termination letter is particularly important where deductions are being made, as it demonstrates transparency and sets out the contractual basis for the deduction. Employers should also keep a record of all communications, including emails, letters and payroll slips. These may be required if the employee challenges the calculation or brings an unlawful deduction claim.

Section D has outlined the HR processes employers should implement to support accurate holiday calculations at termination. Clear policies, robust record-keeping and effective communication ensure employers meet their legal obligations and maintain a professional offboarding process.

FAQs

This section addresses the most common questions employers and HR professionals face when calculating holiday entitlement for employees leaving a job. Each answer reflects statutory requirements and best practice to minimise risk and provide clarity when final pay is being prepared.

Do employees accrue holiday during notice?

Yes. Employees continue to accrue statutory holiday throughout their notice period, whether they are working, on garden leave or absent due to sickness or maternity leave. If the employer makes a payment in lieu of notice (PILON) and the contract contains a PILON clause, employment ends immediately and accrual stops on that date. If the employer pays PILON without a contractual PILON clause, the payment may be treated as damages and holiday may accrue during the notional notice period.

How is holiday calculated for part-year or irregular hours workers when they leave?

Since the 2024 reforms, part-year and irregular hours workers accrue holiday based on the statutory framework introduced for leave years beginning on or after 1 April 2024. Employers may use the percentage accrual method of 12.07% of hours worked in each pay period for workers who fall within the statutory definitions. Transitional rules apply where leave years straddle 1 April 2024. When calculating holiday pay for leavers, employers must ensure the calculation reflects the worker’s average earnings using the correct paid weeks in the 52-week reference period.

Can employers require employees to take holiday during notice?

Yes. Employers can require employees to take statutory annual leave during their notice period, provided they give notice at least twice the length of the leave that the employee is required to take. Different rules may apply to contractual leave depending on the contract wording. Employers should act reasonably and communicate decisions clearly to avoid disputes.

How should bank holidays be treated in a final holiday calculation?

It depends entirely on the contract. There is no statutory right to paid bank holidays. If bank holidays form part of the total annual entitlement, they must be included in the pro-rata calculation. If bank holidays are an additional contractual benefit, they will generally accrue proportionately unless the contract expressly excludes this. Bank holidays falling after the employee’s leaving date are not normally payable unless the contract states otherwise.

Can employers deduct overtaken holiday from final pay?

Yes, but only if there is a clear contractual clause permitting the deduction or the employee has given prior written consent. Without such authority, the deduction will be unlawful. Employers must also ensure that the deduction does not reduce the worker’s pay for the relevant pay reference period below the National Minimum Wage.

What evidence should HR keep when calculating accrued leave for leavers?

Employers should retain documentation of the accrual method used, the employee’s total entitlement, leave taken to date, working patterns, variable pay calculations and all communications with the employee regarding entitlement. This evidence is essential in the event of an unlawful deduction claim or dispute about the accuracy of the calculation.

Conclusion

Calculating holiday entitlement correctly when an employee leaves a job is a critical part of lawful and professional offboarding. Employers must apply the Working Time Regulations 1998, review contractual provisions and ensure that any payment in lieu or deduction for overtaken leave is based on a clear legal foundation. Mistakes in this area often lead to unlawful deduction claims, payroll disputes or reputational issues that could have been avoided through consistent processes and transparent communication.

For every departing employee, HR and payroll should work together to confirm the employee’s total entitlement, calculate pro-rata accrual to the leaving date, establish whether bank holidays or contractual enhancements apply and ensure that the holiday pay is based on normal remuneration. Employers must also comply with the statutory 52-week reference period for variable pay workers and the 2024 accrual rules for irregular hours and part-year workers.

A clear calculation record and an accurate, well-explained final payslip help protect the organisation from risk while giving the departing employee confidence that they have been treated fairly. When policies are drafted carefully and applied consistently, final holiday calculations become a straightforward part of managing employee exits.
