Holiday-pay rules in the UK have shifted more than once in the past decade, and most SME managers will have heard contradictory advice from one source or another. Rolled-up holiday pay sits right in the middle of that confusion — banned for most workers, then partially permitted again, with strict conditions.

This guide answers the rolled-up holiday pay question first, then walks through the leave FAQs that come up most often: accrual, carry-over, sickness during holiday, bank holidays and the rest. Pair it with reliable HR software and time and attendance records so the answers translate into clean practice.

What is rolled-up holiday pay?

Rolled-up holiday pay is the practice of adding an extra percentage to an hourly rate so that holiday pay is paid as the worker earns, rather than when the worker actually takes leave. The shorthand "12.07% on top" comes from the calculation that statutory holiday entitlement (5.6 weeks) is roughly 12.07% of the working year for a full-time worker.

Is it legal in the UK?

For most workers, rolled-up holiday pay was found unlawful by the European Court of Justice in 2006 and the practice fell out of use. The position changed in April 2024 for " irregular hours" and " part-year" workers under updated UK regulations. For those workers, employers can choose between accruing holiday at 12.07% of hours worked or paying it as a 12.07% uplift on each pay period — provided strict conditions are met.

For workers on regular full- or part-time hours with a fixed pattern, rolled-up holiday pay remains unlawful. The reform was deliberately narrow.

What are the conditions for using it lawfully?

Where rolled-up holiday pay is permitted, the rules require the employer to:

• Identify clearly which workers are " irregular hours" or " part-year" under the legal definitions.
• Pay the 12.07% uplift on top of the worker's normal hourly rate, calculated on each pay period.
• Show the holiday pay as a separate line on the payslip — not buried inside the normal hourly rate.
• Keep records that demonstrate the uplift has been correctly applied for the legally required retention period.

If the conditions are not met, the practice is unlawful and the worker can claim unpaid holiday on top of what they have already received.

When is rolled-up holiday pay a bad idea anyway?

Even where it is legal, rolled-up holiday pay creates two practical problems: workers may not feel they can afford to take leave (because no separate pay arrives during the leave period), and employers can find themselves with workers running short on actual rest. The Working Time Regulations exist for a reason; if your team are not actually taking leave, the legal-pay question is the easy half of the problem.

Holiday accrual for irregular-hours workers

For workers whose hours change week to week, statutory holiday accrues at 12.07% of hours worked in each pay period — so a 30-hour week generates roughly 3.62 hours of holiday. Decent rota and workforce management software calculates this automatically, alongside the rota itself.

Holiday carry-over: what is allowed?

The default rule is that statutory holiday must be taken in the holiday year in which it accrues. Limited carry-over is permitted in narrow circumstances — long-term sickness, family leave, or where the employer prevented the worker from taking leave. Contractual holiday on top of the statutory minimum can be carried over by agreement.

Bank holidays

There is no automatic statutory right to a paid bank holiday off. Bank holidays can either form part of the 5.6-week statutory entitlement or be additional, depending on the contract. The contract should state which it is. Workers required to work bank holidays are not automatically entitled to a premium rate unless their contract says so.

Sickness during holiday

If a worker becomes genuinely ill during a period of booked annual leave, they can ask for the affected days to be reclassified as sickness rather than leave, so that the holiday days remain available to be taken later. Employers can apply the same notification and certification rules as they would for any other sickness absence.

Does holiday accrue during sickness, family leave and other absences?

Yes. Statutory holiday continues to accrue during sick leave, maternity leave, paternity leave, adoption leave, parental leave and shared parental leave. Workers do not lose their statutory holiday entitlement just because they were absent.

Calculating holiday pay for variable-hours workers

Holiday pay for variable-hours workers must reflect what they would have earned had they worked, including regular overtime, commission and shift premiums where these are sufficiently regular. The current reference period for pay calculation is 52 weeks (excluding any week with no pay).

Getting this wrong is one of the most common SME tribunal exposures. Annaizu's time and attendance data and HR software let you calculate holiday pay against an accurate 52-week reference period, rather than estimating.

The basic checklist for SMEs

• Confirm whether each worker is regular-hours, irregular-hours or part-year.
• Decide whether to use rolled-up holiday pay (only for irregular/part-year) or pay holiday on the day it is taken.
• Show holiday pay as a separate line on payslips.
• Calculate variable-hours holiday pay using the 52-week reference period.
• Track accrual, requests, balances and carry-over in one place.
• Encourage workers to actually take their leave — that is the whole point.

Conclusion

‍

The short version: rolled-up holiday pay is legal again, but only for narrowly defined irregular-hours and part-year workers, and only if the technical conditions are met. For everyone else, holiday pay must still be paid when leave is taken. The biggest risks for SMEs are not in the headline question but in the surrounding admin — accrual calculation, the 52-week reference, payslip presentation. Get those right, supported by accurate rota and HR records, and the FAQs answer themselves.
