There is no automatic right to bank holidays off
A surprise for many employers: UK workers have no statutory right to take bank holidays as paid time off. The 8 bank holidays in England and Wales can be counted as part of the 5.6 weeks of statutory holiday. Whether staff get them off, and whether that is on top of or within their allowance, depends on the contract.
Why part-timers need pro-rating
The fairness problem comes from timing. Most bank holidays land on a Monday. Consider two people who each work 3 days a week:
- One works Monday to Wednesday and would benefit from nearly every bank holiday.
- One works Wednesday to Friday and would benefit from almost none.
Same hours, wildly different benefit. The Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000 mean you should not leave part-timers worse off than comparable full-time staff. The clean fix is to pro-rata bank holidays.
The “pot of hours” approach
Instead of tying bank holidays to specific dates, give each part-timer a proportionate pot of bank holiday hours, then let them draw it down against whichever bank holidays fall on their working days. The pot is sized by the hours they work compared with a full-timer.
Part-timer’s bank holiday pot = full-time bank holiday hours × (part-time hours ÷ full-time hours)
Worked example
Assume a 5-day, 37.5-hour full-time week, and 8 bank holidays a year:
- A full-timer’s bank holidays = 8 days × 7.5 hours = 60 hours.
- A part-timer works 3 days / 22.5 hours a week โ that is 22.5 ÷ 37.5 = 0.6 of full-time.
- Their pot = 60 × 0.6 = 36 hours of bank holiday time.
They now draw those 36 hours against bank holidays that fall on their working days โ fair regardless of which days they work. To size allowances and pots quickly, use our pro-rata holiday calculator.
| Worker | Share of full-time | Bank holiday pot |
|---|---|---|
| Full-time (37.5h) | 1.0 | 60 hours |
| Part-time (22.5h) | 0.6 | 36 hours |
| Part-time (15h) | 0.4 | 24 hours |
Working in hours makes this easy
Pro-rating bank holidays is far simpler when you track leave in hours rather than whole days, so a “pot” is a natural unit. Rotaleave’s hourly holiday tracking handles bank holiday pots per person automatically. For the wider pro-rata method, see our guide on calculating holiday for part-time staff.
Check the official sources
This is general guidance, not legal advice. Bank holiday and part-time rules are set out on gov.uk and Acas โ check them for your specific contracts and any nation-specific holidays (Scotland and Northern Ireland differ).
