UK holiday entitlement — questions
Almost all UK workers are legally entitled to 5.6 weeks of paid annual leave a year. For someone with a regular pattern, multiply the days they work per week by 5.6 — so 5 days × 5.6 = 28 days, and 3 days × 5.6 = 16.8 days. The statutory figure is capped at 28 days, so 6- and 7-day workers still get 28. Bank holidays can be counted within it or given on top — the contract decides.
Part-timers get the same 5.6 weeks — a “week” is just their week. Someone working 2 days a week gets 5.6 × 2 = 11.2 days. If your company gives full-timers more than statutory (say 25 days plus bank holidays), pro-rate it: 25 × 2⁄5 = 10 days, plus a pro-rated share of the bank holidays if they're given on top.
12.07% is the statutory accrual rate for irregular-hours and part-year workers: 5.6 weeks of leave divided by the 46.4 weeks actually worked. For leave years starting on or after 1 April 2024, these workers accrue leave at 12.07% of the hours they work in each pay period — work 104 hours in a month and you accrue 104 × 12.07% ≈ 12.6 hours of paid leave.
A proportional share. Take their full-year entitlement and multiply by the fraction of the leave year they're employed. Someone on 28 days joining with 3.5 months left gets 28 × 3.5⁄12 ≈ 8.2, rounded up to 8.5 days. Leavers accrue up to their final day — anything accrued but untaken is paid in lieu on the final payslip.
