Prison Officer Payslip Explained 2026/27
Why Your £34,928 Includes 20% Unsocial Hours — and What It Means
Last updated: 16 September 2026 · 2026/27 UK tax year
The #1 question new prison officers have is "where is my 20% unsocial hours payment?". Here is the complete breakdown of your HMPPS payslip, from market supplements to the Alpha pension.
The 20% Unsocial Hours Allowance: Why It's Already In Your Pay
New recruits often look at their first payslip expecting to see a base salary PLUS an extra 20% added for Unsocial Hours Working (UHW). This is not how it works. The advertised starting salaries (e.g. £34,928) already have the 20% baked into them. You will not see a separate +20% line item on your payslip.
Prison officers work a variety of shifts, including nights, weekends, and bank holidays. To compensate for this, you receive a 20% Unsocial Hours Working allowance. Because it is a permanent part of your contract, it is consolidated into your advertised base salary and is fully pensionable.

Market Supplements — Non-Pensionable, Non-Guaranteed
To attract and retain staff in notoriously difficult or expensive areas, HMPPS offers "Market Supplements" at specific prisons. These currently range from £1,500 (e.g., Grendon) up to £3,500 (e.g., Aylesbury).
- Tax: They are fully subject to Income Tax and National Insurance.
- Pension: They are non-pensionable. They will not increase your Alpha pension contributions or your final retirement payout.
- Security: They are not guaranteed forever. For example, current supplements are guaranteed until March 2027, after which they could theoretically be reviewed or withdrawn. (Do not rely on them for your mortgage!).
The Civil Service Alpha Pension
Prison officers are enrolled in the Civil Service Alpha pension scheme (a Defined Benefit CARE scheme). Because the 20% UHW is consolidated into your base pay, it counts towards your pension.
Most prison officers fall into the 5.45% employee contribution tier (for salaries between £21,587 and £48,105). The employer (HMPPS) contributes a massive 28.97% on top of this. The Alpha scheme operates under a "net-pay arrangement", meaning your pension contribution is deducted before tax, giving you automatic tax relief.
PSPRB 2026/27 — When Is the Next Prison Officer Pay Rise?
Prison officer pay is not negotiated in the same way as standard civil servants. It is recommended by the independent Prison Service Pay Review Body (PSPRB). The review process for 2026/27 is currently live, with evidence submitted by HMPPS and the POA union. The final award is typically announced and implemented in the spring (often backdated if delayed).
Fair & Sustainable vs Legacy Contracts
If you joined the service after 2014, you are on a "Fair & Sustainable" (F&S) contract. The pay structures on this page are for F&S staff.
Older staff may still be on "Legacy" closed-grade contracts. While legacy base pay can sometimes appear higher, legacy staff often do not receive the same annual PSPRB uplifts, as the government's stated goal is to transition all staff onto the F&S structure.
