NHS holiday allowance 2026/27 (Agenda for Change)
NHS staff get more than the statutory minimum. Full-time (37.5 hours) entitlement depends on continuous NHS service, with 8 bank holidays on top:
| NHS service | Annual leave | In hours |
|---|---|---|
| Under 5 years | 27 days | 202.5 hours |
| 5 to 10 years | 29 days | 217.5 hours |
| Over 10 years | 33 days | 247.5 hours |
Work out your exact pro-rata NHS allowance with the NHS annual leave calculator.
Pro rata calculation: Part-time employees receive a proportional share of the full-time entitlement. For example, someone working 3 days a week with 28 days entitlement gets 3/5 × 28 = 16.8 days.
Starters and leavers: Employees who join or leave mid-year are entitled to a proportion of their annual allowance based on the months worked.
Holiday pay on leaving: When an employee leaves, they may be owed payment for unused holiday days. This is calculated using their daily rate of pay.
What is the statutory holiday entitlement in the UK?
All UK workers are legally entitled to 5.6 weeks of paid holiday per year, capped at 28 days. This applies to full-time, part-time, agency, and zero-hours contract workers.
How do you calculate pro rata holiday?
Divide the employee's working days/hours by the full-time equivalent and multiply by the full-time entitlement. E.g. 3 days ÷ 5 days × 28 = 16.8 days.
Can bank holidays be included in the 28 days?
Yes. Employers can include the 8 UK bank holidays within the 28-day statutory minimum, or offer them on top as additional leave.
What happens to unused holiday when someone leaves?
The employee is entitled to pay in lieu for any accrued but untaken holiday. Equally, if they've taken more than their accrued entitlement, the employer may deduct the difference.
