If you work for the NHS under Agenda for Change (AfC) terms and conditions, your annual leave entitlement is determined by how long you've been in continuous NHS service. This applies to the vast majority of NHS staff in England — nurses, healthcare assistants, admin staff, allied health professionals, pharmacists, radiographers, and many more. Understanding exactly how much leave you're entitled to is important for planning your year, managing your wellbeing, and knowing your rights as an employee.
Annual leave is one of the most valued benefits of working in the NHS. Along with a generous pension scheme and job security, the leave allowance under Agenda for Change is among the best in the public sector. But the rules can be confusing — especially for part-time workers, those who've recently changed trusts, or staff who've had breaks in service. This guide breaks it all down clearly.
Entitlement by length of service
There are three tiers of annual leave entitlement under Agenda for Change, all based on completed years of continuous NHS service. These are set out in Section 13 of the NHS Terms and Conditions of Service Handbook:
- 0 to 4 years of service: 27 days per year (plus 8 bank holidays)
- 5 to 9 years of service: 29 days per year (plus 8 bank holidays)
- 10 or more years of service: 33 days per year (plus 8 bank holidays)
At the highest tier, this means up to 41 days of total paid leave per year — one of the most generous allowances of any employer in the UK. These figures apply to full-time staff working the standard 37.5-hour week. Part-time staff receive a proportional entitlement, which we'll cover below.
It's worth noting that your leave entitlement increases automatically once you reach the 5-year and 10-year milestones. You don't need to apply for the increase — it should be reflected in your leave balance by your employer's HR system. If it isn't, raise it with your line manager or HR department.
How pro-rata leave works for part-time staff
If you work fewer than 37.5 hours per week, your annual leave is calculated on a pro-rata basis. The formula is straightforward:
(Your weekly contracted hours ÷ 37.5) × full-time entitlement in days = your entitlement in days
For example, if you work 22.5 hours per week and have 27 days of full-time entitlement, your calculation would be: 22.5 ÷ 37.5 × 27 = 16.2 days. Many trusts convert this into hours for easier tracking, since part-time staff often work different shift lengths on different days.
In hours, the same calculation would be: 22.5 ÷ 37.5 × (27 × 7.5) = 121.5 hours of annual leave per year. When you book leave, each day off uses the number of hours you were scheduled to work that day — so a 12-hour shift uses 12 hours of leave, while a 4-hour shift uses only 4.
Why hours-based tracking matters
Hours-based leave tracking is fairer for part-time staff with variable shift patterns. If you work two long days and one short day, days-based tracking could disadvantage you — taking a day off during a 12-hour shift would use the same 'one day' as taking off during a 4-hour shift, even though the impact is very different.
Most NHS trusts now use hours-based leave tracking for part-time workers. If your trust still uses days and you feel it's unfair, speak with your union representative or HR team about switching to an hours-based system.
Bank holidays — a separate entitlement
A common misconception is that bank holidays are taken from your annual leave allowance. They're not. Under Agenda for Change, the 8 UK bank holidays are a separate entitlement on top of your annual leave days.
For full-time staff, this means you get your annual leave days plus 8 bank holiday days. If a bank holiday falls on a day you're scheduled to work, you get the day off. If it falls on a non-working day, you receive the equivalent time in hours to use another day.
Bank holidays for part-time staff
Part-time workers receive a proportional bank holiday allowance. The calculation is: (your weekly hours ÷ 37.5) × 8 days × 7.5 hours = your bank holiday hours. For someone working 22.5 hours per week, this would be: 22.5 ÷ 37.5 × 60 = 36 hours of bank holiday allowance.
These hours are added to your leave balance and can be used flexibly. Whether or not a bank holiday falls on your normal working day, the hours are yours to take when it suits you — subject to your manager's approval.
What counts as continuous NHS service?
Your leave entitlement is based on continuous NHS service, which includes time spent with any NHS employer in England. This means if you move between trusts, your service length carries over for leave purposes — you don't start from scratch.
Several types of service count towards your continuous service record:
- Direct moves between NHS trusts — as long as there's no significant gap
- NHS Bank work — if it's continuous and regular
- Secondments — time on secondment to another NHS body or approved organisation
- Maternity, paternity, and adoption leave — all count as continuous service
- Sickness absence — continuous service is maintained during sick leave
- Career breaks — many trusts offer formal career break schemes that preserve service
Breaks in service
Short breaks in service (typically up to 12 months) may still count, depending on the reason and your trust's policy. If you leave the NHS and return within a reasonable timeframe, your previous service may be recognised — but this isn't automatic. Always ask your new employer's HR team to confirm your service date and ensure your leave entitlement reflects your full history.
If you've worked in the NHS in Scotland, Wales, or Northern Ireland, your service may also be recognised, but the rules vary. Check with your employer directly.
Mid-year starters and leavers
If you join the NHS part-way through the leave year, your entitlement is calculated on a pro-rata basis for the remaining months. For example, if you start in July and your trust's leave year runs April to March, you'd receive 9/12 of your full entitlement.
Similarly, if you leave part-way through the year, your employer will calculate how much leave you've accrued. If you've taken more than your accrued amount, the difference may be deducted from your final pay. If you've taken less, you'll receive payment in lieu of the unused days.
Our Annual Leave Calculator includes a 'Months to calculate' option specifically for this scenario — select the number of months remaining in your leave year to get your adjusted entitlement.
Carrying over unused leave
Under Agenda for Change, you can carry over unused annual leave to the next leave year — but the amount is subject to your trust's local policy. Some trusts allow up to 5 days (or equivalent hours) to be carried forward, while others may be more or less generous.
During the COVID-19 pandemic, many trusts introduced temporary provisions allowing staff to carry over larger amounts of leave. Some of these provisions have been extended, but they vary widely between employers. If you have unused leave approaching the end of the leave year, speak with your manager early to plan how to use it or apply for a carry-over.
Requesting and booking leave
Annual leave must normally be agreed with your line manager in advance. Most trusts require a certain amount of notice — typically twice the length of the leave being requested (e.g., 2 weeks' notice for 1 week off). However, this varies by department and local policy.
During popular periods like school holidays, Christmas, and summer, competition for leave can be high. Many teams use a rota system or first-come-first-served approach to manage requests fairly. If you have specific dates you need off, it's always best to submit your request as early as possible.
Can your employer refuse leave?
Yes — your employer can refuse a leave request if it conflicts with service needs. However, they must ensure you have a reasonable opportunity to take your full entitlement during the leave year. If you're consistently unable to take leave due to staffing pressures, raise this with your manager, HR, or union representative.
Annual leave and other types of absence
Your annual leave entitlement continues to accrue during periods of sickness absence, maternity leave, paternity leave, and adoption leave. This means you don't lose leave because you've been off sick — your entitlement builds up as normal, and you can use it when you return.
If you're on long-term sick leave and cannot take your leave before the end of the leave year, you may be allowed to carry it over. Under EU working time regulations (retained in UK law), you must be able to take at least your statutory minimum of 28 days. Many trusts have policies to accommodate this.
Key things to remember
