If you work for the NHS through a staff bank or an agency, your annual leave entitlement works differently from permanently employed colleagues. Many bank and agency workers assume they don't get annual leave at all — but that's not true. Every worker in the UK, regardless of contract type, has a legal right to paid holiday. The question is how it's calculated and delivered.
This guide explains how annual leave works for both NHS bank workers and agency staff, the key differences from Agenda for Change permanent contracts, and how to make sure you're getting what you're owed.
Your statutory right to paid holiday
Under the Working Time Regulations 1998, every worker in the UK — including casual, zero-hours, bank, and agency workers — is entitled to a minimum of 5.6 weeks of paid annual leave per year. For a full-time worker, that equates to 28 days. For part-time workers, it's proportional to their hours.
This is a legal minimum that cannot be contracted away. Even if your contract doesn't mention holiday pay, you're still entitled to it.
NHS bank workers
NHS staff bank workers are employed directly by a trust on a flexible, as-and-when basis. You pick up shifts that suit you, but you don't have guaranteed hours. How your leave works depends on how your trust's bank operates:
Rolled-up holiday pay
Many NHS banks use rolled-up holiday pay, where an additional percentage (typically 12.07%) is added to your hourly rate for every shift you work. This percentage represents your holiday pay, paid as you earn rather than when you take time off.
For example, if your base hourly rate is £15.00, you'd receive £15.00 + £1.81 (12.07%) = £16.81 per hour, with the extra £1.81 being your holiday pay. The trade-off is that when you do take time off, you don't receive separate holiday pay — it's already been included in every shift.
Accrued leave with booking
Some trusts operate their banks differently, allowing workers to accrue leave in hours and book time off in a similar way to permanent staff. If your bank operates this way, you'll see a leave balance build up based on the hours you work.
Which system does your trust use?
Check your bank registration paperwork or ask your bank office. It's important to know which system applies to you, because it affects whether you need to actively 'save' for periods without work or whether you can book leave and receive pay for it.
Agency workers
Agency workers — employed by an agency and placed at NHS trusts — have their holiday arrangements managed by the agency, not the trust. Your rights depend on your contract with the agency and the Agency Workers Regulations 2010.
Rolled-up holiday pay (most common)
Most nursing and healthcare agencies use rolled-up holiday pay, adding 12.07% to your hourly rate. This is the most common arrangement for agency NHS workers. You should see the holiday element itemised on your payslip — if you don't, ask your agency to clarify.
The 12-week qualifying period
Under the Agency Workers Regulations, after 12 weeks in the same role at the same trust, you become entitled to the same basic working conditions as directly employed staff doing the same job. This includes pay parity but doesn't automatically change your holiday arrangements — those remain with your agency.
However, the 12-week rule can be relevant if your agency's holiday provision is less generous than the trust's. If in doubt, raise it with your agency and the trust's HR department.
How 12.07% is calculated
The 12.07% figure comes from dividing the statutory holiday entitlement (5.6 weeks) by the remaining working weeks in the year (46.4 weeks): 5.6 ÷ 46.4 = 0.1207 or 12.07%.
This means for every 46.4 weeks you work, you accumulate enough holiday pay for 5.6 weeks off. It's a fair and mathematically sound approach, but it relies on you setting aside money (or time) for the weeks when you're not working.
Key differences from permanent AfC contracts
- Entitlement amount: Permanent AfC staff get 27–33 days plus 8 bank holidays (up to 41 days total). Bank and agency workers get the statutory minimum of 28 days unless their contract offers more.
- Service-based increases: Permanent staff earn extra days at 5 and 10 years. Bank and agency workers don't benefit from service-based increases unless their contract specifically provides for it.
- Bank holidays: Permanent staff get bank holidays as a separate entitlement. For bank/agency workers, bank holidays are usually included within the 28-day statutory minimum.
- Carry-over: Permanent staff can carry over unused leave. Bank/agency workers with rolled-up pay have already received their holiday pay and typically can't carry anything over.
Are you being short-changed?
Unfortunately, some agencies and even some NHS banks don't always get holiday pay right. Here are warning signs:
- Your payslip doesn't itemise holiday pay separately
- Your hourly rate seems unusually high but there's no holiday element shown
- You're told you're 'not entitled' to holiday pay as a bank worker
- The holiday percentage is less than 12.07%
If you suspect an issue, raise it with your employer (agency or trust bank office) in the first instance. If that doesn't resolve it, contact ACAS for free advice or speak with a union representative. You can also check the ACAS guidance on holiday entitlement for detailed information on your rights.
Transitioning from bank/agency to permanent
If you move from bank or agency work to a permanent Agenda for Change contract, your holiday arrangements change immediately. You'll start accruing leave under AfC rules from your first day. However, your previous bank or agency service may not count towards the service-based leave tiers (27/29/33 days) — this depends on the trust's policy.
Some trusts recognise continuous bank service for leave tier purposes; others don't. Agency service is rarely recognised. If you have significant bank experience, negotiate this during the recruitment process and get any agreement in writing.
Tips for managing leave as a bank or agency worker
- Track your holiday pay. If you receive rolled-up pay, know exactly how much of each shift payment represents holiday money. Consider setting this aside in a separate account.
- Plan for time off. Without booked annual leave, it's tempting to work constantly. Schedule regular breaks — your wellbeing depends on it.
- Keep payslips. If you ever need to prove your holiday pay was included, payslips are your evidence.
- Know the 12-week rule. If you're agency and approaching 12 weeks at the same trust, understand your enhanced rights.
- Use our Annual Leave Calculator to compare what your entitlement would be under a permanent AfC contract — it can help you evaluate the financial case for going permanent.
