Statutory holiday entitlement
28
5 days/week × 5.6 weeks = 28 days (includes bank holidays)
Quick answer: UK statutory holiday is 5.6 weeks a year — 28 days for a 5-day week, including bank holidays. Part-time: days worked × 5.6 (3 days/week = 16.8 days). Irregular hours and zero-hours workers accrue 12.07% of hours worked.
How UK holiday entitlement works
- 5.6 weeks of paid leave for all workers — full-time, part-time, agency, casual and zero-hours.
- For a 5-day week that is 28 days; the statutory cap is 28 days even if you work 6 or 7 days.
- Employers can include the 8 bank holidays in England and Wales (9 in Scotland, 10 in Northern Ireland) within the 28 — or give them on top.
- Leave starts accruing from your first day, even during a probation period.
Formulas this calculator uses
| Worker type | Formula | Example |
|---|---|---|
| Full-time, days | days/week × 5.6 (max 28) | 5 × 5.6 = 28 days |
| Part-time, days | days/week × 5.6 | 3 × 5.6 = 16.8 days |
| Part-time, hours | hours × 12.07% | 20 h/wk × 46.4 wk × 12.07% = 112 h |
| Zero / irregular hours | 12.07% of hours worked | 120 h × 12.07% = 14.48 h |
| Joiner / leaver | entitlement × part of year | 28 × 6/12 = 14 days |
12.07% comes from 5.6 ÷ 46.4 (a year of 52 weeks minus 5.6 weeks of leave).
Rolled-up holiday pay (from April 2024)
Employers may pay irregular-hours and part-year workers a clearly itemised 12.07% uplift on each payslip instead of giving time off. It is not allowed for regular-hours staff.
Frequently asked questions
How much holiday do I get if I work 4 days a week?
22.4 days (4 × 5.6), including bank holidays if your employer counts them in the statutory minimum.
Do bank holidays count towards my 28 days?
Your employer chooses. Both approaches are lawful as long as you still get 5.6 weeks of paid leave in total.
What if I start part-way through the leave year?
Your entitlement is pro rated by the fraction of the leave year you are employed. Tick the pro-rata box and set the fraction, or use days employed ÷ 365 × entitlement.
Can my employer round holiday down?
Rounding is acceptable if it stays consistently in the worker's favour — never round 16.8 down to 16.
Is holiday pay based on basic pay only?
No. Holiday pay should reflect normal pay, including regular overtime and commission, averaged over the previous 52 weeks.
