Work out holiday entitlement and pay
Rolled-up holiday pay and the 52-week average for irregular hours workers, per the statutory rules.
Rolled-up holiday pay became lawful again for irregular hours and part-year workers on leave years beginning on or after 1 April 2024, calculated at 12.07% of pay in each pay period [1]. For almost two decades before that it had been unlawful across the board, following a 2006 European Court ruling that a lump sum paid inside the hourly rate discouraged workers from actually taking leave [2].
The method now sits in a narrow lane. It applies to two categories of worker only, it must show as a separate line on the payslip, and it does not replace the duty to let staff take their 5.6 weeks of leave. For every other worker, rolled-up pay remains against the law.
This article explains what rolled-up holiday pay is, which workers it can be used for, how the 12.07% figure is worked out, the payslip and contract conditions that make it lawful, and where employers most often get it wrong.
Key takeaways
- Rolled-up holiday pay is lawful only for irregular hours workers and part-year workers, and only for leave years starting on or after 1 April 2024.
- It is calculated at 12.07% of the worker's total pay in each pay period and paid alongside wages.
- It must appear as a separate, clearly labelled line on the payslip, not folded into the hourly rate.
- For fixed-hours workers it remains unlawful. They must be paid holiday pay at the point they take leave.
- Almost all workers keep the right to 5.6 weeks of paid statutory leave a year, up to a 28-day cap.
What rolled-up holiday pay actually is
Rolled-up holiday pay spreads a worker's holiday pay across the year by adding a percentage supplement to every hour earned, rather than paying a separate amount when leave is taken [3]. A worker on a £12 hourly rate with 12.07% rolled up receives an extra £1.45 an hour, itemised on the payslip as holiday pay.
The appeal for employers with a fluctuating headcount is administrative. Casual and seasonal staff can have pay that changes every week, and calculating a 52-week average each time someone books a day off is heavy work. Rolling the pay up settles the holiday cost as it accrues, so the payroll never has to reconstruct an average at the moment of leave.
The trade-off is that the worker receives no separate payment during the weeks they are actually off. They have already been paid for that leave across the preceding pay periods. This is precisely why the method was banned for so long, and why the conditions attached to its return matter so much.
Why it was unlawful for almost 20 years
In 2006 the European Court of Justice ruled in Robinson-Steele v RD Retail Services that paying holiday pay inside the ordinary hourly rate breached the Working Time Directive, because a worker who saw no extra money when taking leave might be deterred from taking it at all [2]. The court did allow sums that were genuinely transparent to be offset against holiday pay liability, but the practical effect was to make rolled-up pay unsafe [4].
The right to paid holiday itself sits in the Working Time Regulations 1998, which give almost all workers 5.6 weeks of paid leave a year [5]. That entitlement never went away. What changed in 2024 was the narrow permission to pay part of it in rolled-up form for two specific worker types.
Which workers rolled-up pay can be used for
The return of rolled-up holiday pay was delivered by The Employment Rights (Amendment, Revocation and Transitional Provision) Regulations 2023, which took effect for leave years beginning on or after 1 April 2024 [6]. The permission is limited to two defined categories.
| Worker type | Definition | Rolled-up pay allowed |
|---|---|---|
| Irregular hours worker | Hours are wholly or mostly variable in each pay period under the contract | Yes, from 1 April 2024 |
| Part-year worker | Works only part of the year, with at least a week of unpaid non-working time in the leave year | Yes, from 1 April 2024 |
| Fixed-hours worker | Regular, predictable hours across the year | No, remains unlawful |
An irregular hours worker is one whose paid hours are wholly or mostly variable from one pay period to the next [7]. A part-year worker is contracted for the whole year but has periods of at least a week during the leave year when they neither work nor are paid, the classic example being term-time-only staff.
A worker who does not fall into either category cannot be paid rolled-up holiday pay. For them the older rule stands: holiday pay is paid when leave is taken, using normal remuneration. Employers running a mix of contract types across a business such as small business payroll need to classify each worker correctly, because the same method cannot lawfully be applied to everyone.
The line between irregular and fixed hours
The distinction is not always obvious. A worker on a zero-hours contract who happens to work a steady 20 hours most weeks may still qualify as irregular if the contract makes the hours variable. Conversely, a worker labelled casual who in practice works a fixed shift pattern may be a fixed-hours worker in law. The test rests on the contractual reality of how hours are set, not on the job title [7].
Getting the classification wrong carries real cost. Applying rolled-up pay to a fixed-hours worker is unlawful and exposes the employer to an unlawful deduction claim, while failing to apply it where it is permitted simply loses the administrative saving. Payroll software that tags each worker by category at the point of setup removes the guesswork from every subsequent payrun, which is one reason employers move this classification into their UK payroll software rather than tracking it on a spreadsheet.
Where the 12.07% comes from
The 12.07% figure is not arbitrary. Statutory holiday of 5.6 weeks is expressed as a proportion of the working weeks in a year. A year has 52 weeks, and subtracting the 5.6 weeks of leave leaves 46.4 working weeks. Dividing 5.6 by 46.4 gives 0.1207, or 12.07% [1].
In other words, for every hour actually worked, the worker earns a further 12.07% of an hour as holiday. Applied to pay rather than time, the employer adds 12.07% of the pay earned in a period as rolled-up holiday pay [3].
The 12.07% is a floor, not a fixed rate
The 12.07% is the statutory minimum. It reflects the legal minimum of 5.6 weeks. Where a contract gives more than the statutory minimum, for example a worker with 6.6 weeks of contractual holiday, the employer must recalculate the percentage upward to match [3]. A worker entitled to more generous leave than the statutory floor cannot lawfully be paid the 12.07% minimum.
The percentage also stops being correct if the employer tries to use it as the pay rate for a whole week of leave taken by a worker who is not paid rolled-up. For those workers the amount owed for a week of leave is still the 52-week average, not 12.07% of anything [8]. The 12.07% is an accrual and rolled-up mechanism for the two permitted categories only.
A worked example
The clearest way to see rolled-up pay is with figures. Take a part-year worker paid monthly, whose total pay in a month is £1,000 across variable shifts. The rolled-up holiday supplement is 12.07% of £1,000, which is £120.70 [3].
| Item | Amount |
|---|---|
| Basic pay for hours worked in the month | £1,000.00 |
| Rolled-up holiday pay (12.07%) | £120.70 |
| Total gross pay for the month | £1,120.70 |
The £120.70 appears on the payslip as a separate line, distinct from the £1,000 of basic pay. When the worker later takes a week off, no further holiday payment is made in that week, because the holiday has already been paid as it accrued [3]. The worker still books and takes the leave; they simply do not receive an additional sum for it at that point.
The same logic scales down to weekly pay. A worker earning £300 in a week receives £36.21 of rolled-up holiday pay on top, itemised separately, in that same week [3]. For businesses generating HMRC-compliant payslips at this frequency, the separate line is produced automatically on each run.
The conditions that make it lawful
Rolled-up holiday pay is permitted only when several conditions are met at once. Missing any one of them can render the arrangement unlawful even for an otherwise eligible worker.
- Separate payslip line.** The holiday element must be shown as a distinct, clearly labelled payment on the payslip, not absorbed into the headline hourly rate [3]. Transparency is the whole point: the worker must be able to see the holiday pay.
- Paid with the wages.** The supplement is paid at the same time as the pay for the work done in that period, not banked and released later [3].
- Correct worker category.** The worker must genuinely be an irregular hours or part-year worker [7].
- At least 12.07%.** The rate must be at least 12.07%, adjusted upward where contractual holiday exceeds the statutory minimum [3].
- Notice to the worker.** Employers should tell workers before moving to rolled-up pay, and doing so may require a change to the employment contract [3].
Leave must still be taken
A worker paid rolled-up holiday pay keeps the right to take their statutory leave. The employer cannot treat the rolled-up payment as a reason to discourage or refuse time off, and must still allow the worker to take 5.6 weeks away from work [5]. An irregular hours or part-year worker also must not lose holiday pay while off sick or on statutory family leave, so the accrual continues to build during those absences [3].
This protects the original purpose of paid holiday. The reason rolled-up pay was unlawful for so long was the risk that workers, seeing no separate payment, would skip their rest. The conditions attached to its return are designed to keep the rest in place while easing the arithmetic.
Rolled-up pay versus the 52-week average
Employers with eligible workers face a choice: use rolled-up pay, or keep calculating a 52-week average each time leave is taken. Rolled-up pay is optional, not compulsory [1].
| Feature | Rolled-up holiday pay | 52-week average |
|---|---|---|
| Eligible workers | Irregular hours and part-year only | All variable-pay workers |
| When paid | Each pay period, with wages | When leave is taken |
| Admin at point of leave | None | Recalculate average each time |
| Payslip treatment | Separate line every period | Paid in the leave period |
| Risk area | Correct category and clear labelling | Correct reference period |
The 52-week method averages pay over the previous 52 paid weeks, skipping weeks with no pay and looking back up to 104 weeks to find enough paid weeks [8]. It gives a precise figure at the moment of leave but demands work each time. Employers can read the mechanics in detail in the guide to the 52-week holiday pay average. Rolled-up pay front-loads the calculation into every payrun and removes it from the leave event entirely. Accountants weighing the two approaches across a client base often standardise the choice inside a payroll bureau platform so every scheme is handled the same way.
What counts towards the pay the percentage is applied to
Because rolled-up pay is a percentage of total pay in the period, the definition of pay matters. Holiday pay generally must reflect normal remuneration, which includes regularly worked overtime, results-based commission and allowances tied to the role [9]. For rolled-up pay, the 12.07% is applied to the total pay earned in the period, so those regular elements feed into the figure automatically as they are paid [3]. One-off expenses that reimburse a cost rather than reward work are not part of normal pay and should not inflate the base [9].

Conclusion
Rolled-up holiday pay is a narrow permission, not a general shortcut. It works for irregular hours and part-year workers, at 12.07% or higher, paid transparently on every payslip, and it leaves the underlying right to rest untouched. Used inside those limits it removes a real administrative burden from businesses that run variable-hours teams. Used outside them, on a fixed-hours worker or without a clear payslip line, it becomes an unlawful deduction waiting to be challenged.
The wider direction of travel is towards clearer, more automated holiday accounting. As payroll compliance moves further inside the software platforms that businesses already use, the classification of workers, the accrual of leave and the itemisation of holiday pay increasingly happen at the point of the payrun rather than in a separate spreadsheet exercise. Payroll built around that logic, such as the Moonworkers UK payroll engine, treats the worker category as a setting and the 12.07% as a rule, so the right method follows each worker automatically.
Frequently asked questions
Is rolled-up holiday pay legal in the UK?
Rolled-up holiday pay is lawful only for irregular hours workers and part-year workers, and only for leave years beginning on or after 1 April 2024. For all other workers, including those on fixed regular hours, it remains unlawful, and holiday pay must be paid at the time the leave is actually taken.
How is rolled-up holiday pay calculated?
It is calculated at a minimum of 12.07% of the worker's total pay in each pay period. The 12.07% comes from dividing the statutory 5.6 weeks of holiday by the 46.4 working weeks in a year. Where a worker has more than the statutory minimum holiday, the percentage must be increased to match their entitlement.
Does rolled-up holiday pay have to be shown separately on the payslip?
Yes. The holiday element must appear as a distinct, clearly labelled line on the payslip, separate from basic pay. If it is folded into the hourly rate and not visible, the arrangement fails the transparency condition and can be treated as unlawful, even for an otherwise eligible worker.
Can a worker still take holiday if they get rolled-up pay?
Yes. A worker paid rolled-up holiday pay keeps the full right to take their 5.6 weeks of statutory leave. They receive no additional payment during those weeks because the holiday pay has already been paid as it accrued, but the employer must still allow and not discourage the time off.
