The HMPPS Fair and Sustainable pay structure
Prison officers employed directly by His Majesty's Prison and Probation Service (HMPPS) are paid under the Fair and Sustainable (F&S) pay framework, introduced from 2014. This replaced the older closed-grade structure for new entrants and is now the predominant pay system across the public prison estate. The framework uses numbered pay bands: Operational Support Grade (OSG) staff generally sit at Band 2, new-entrant prison officers at Band 3, experienced officers at Band 3 with pay progression, and Custodial Managers at Band 4 or above.
Within each band there is a minimum and maximum pay point, and officers progress through the scale year by year, subject to satisfactory performance and no formal warnings. For 2025/26, Band 3 entry-level pay started at approximately £30,001 nationally, with the top of Band 3 at around £33,500. Band 4 runs from roughly £34,000 to £39,500. These are basic pay figures only, before any allowances. Pay for 2026/27 is subject to the annual PSPRB recommendation and government acceptance - check the current HMPPS pay circular for the confirmed figures before treating any percentage as settled.
Some prisons in high-cost or high-pressure locations pay a market supplement on top of the band rate, currently ranging from 1,500 to £3,500. This is not guaranteed and can be withdrawn if the establishment's recruitment challenges ease. It should be a named separate line on your payslip. Private prison operators (Serco, G4S, Sodexo) run their own pay structures that may differ materially from HMPPS F&S bands; check your contract if you work for a contracted-out prison.
Band 3 officers are contracted for either 37 or 39 conditioned hours per week, depending on the establishment's hours agreement. The contracted hours affect both the basic pay calculation and the way unsocial hours are treated. Officers on 39 hours work two more hours per week than the standard Civil Service week; this is built into the pay band calculation rather than paid separately. Know your conditioned hours from your contract, as they affect how overtime and TOIL are managed.
What a prison officer payslip looks like
The payments section typically shows basic pay first, then the Required Hours Addition (RHA), then Unsocial Working Hours (UWH), then any overtime or payment plus amounts, and finally any market supplement. Each is a separate line. Basic pay divided by the period should match your band rate divided by 12. The RHA should equal exactly 20 percent of your basic pay for the period - no more, no less.
The deductions section shows PAYE income tax, Class 1 National Insurance, and your Civil Service alpha pension contribution. The alpha deduction is based on the full pensionable pay including RHA, since RHA is a pensionable allowance. This is why the pension deduction looks larger than you might expect from basic pay alone.
Year-to-date figures on the right track cumulative gross, tax and pension from the previous 6 April. For a prison officer with variable shift patterns, the year-to-date gross is the most reliable check on whether total pay is on track. If you divide year-to-date gross by the months elapsed, the resulting monthly average should be close to your expected monthly earnings including allowances.
Time off in lieu (TOIL) accrues when you work additional hours or cover for other staff. TOIL does not usually appear on the payslip unless you are taking payment in lieu of taking it as leave - in which case a "TOIL payment" or "payment in lieu" line should appear. If TOIL has been authorised but neither taken nor paid, it should be tracked in your establishment's own records system; challenge your employer if the balance looks wrong.
Prison Officer pay bands (UK 2026/27)
Gross figures reflect typical national pay-scale and ONS ASHE 2024 levels. Net figures are a simplified estimate using 2026/27 PAYE bands and a 5% pension assumption. Your real pension rate and tax code may differ - see the pension section below.
| Band | Gross / year | Net / year | Net / month |
|---|---|---|---|
| Lower (25th percentile) | £32,000 | £25,272 | £2,106 |
| Median | £36,800 | £28,488 | £2,374 |
| Upper (75th percentile) | £42,000 | £31,972 | £2,664 |
Pay and additions on a prison officer payslip
- Basic payYour annual F&S band rate divided by 12. Check it against the published HMPPS pay circular for your band and pay point. If you have moved to a new pay point through annual progression, the April payslip should show the higher amount. If it does not, contact HR in writing.
- Required Hours Addition (RHA)A pensionable allowance paid to Band 3 officers at exactly 20 percent of basic pay, recognising that the role regularly involves unsocial and unpredictable hours as part of normal duties. It is not overtime - it is built into the standard package. Because it is pensionable, it increases your Civil Service alpha pension contributions and feeds into your pension accrual. Verify that the line shows exactly 20 percent of your basic pay for that period.
- Unsocial Working Hours (UWH) paymentUnlike NHS Section 2 enhancements, UWH for prison officers is not calculated shift by shift as a percentage of basic pay. It is a consolidated allowance - fixed monthly amount or periodic calculation - set within the HMPPS framework and potentially varying by establishment. When you transfer to a new prison, the first payslip is the one to check: if the UWH line carries over from your previous establishment at the wrong rate, it may persist unchallenged for months.
- Market supplementBetween 1,500 and £3,500 per year at qualifying establishments, payable monthly as a fraction. The supplement is non-pensionable - it must not feed into your alpha pension calculation base - and HMPPS can withdraw it unilaterally if the recruitment situation changes. Check the payslip line amount against the supplement confirmed in your posting offer.
- Overtime and payment plusAt Band 3, overtime beyond conditioned hours is typically paid at plain time for the first few hours then at an enhanced rate - verify the current rate in your local pay agreement, as it has changed over successive PSPRB cycles. "Payment plus" appears in some HMPPS establishments as a distinct additional shift premium; it should show the rate used, not just a total, so the hours can be verified.
- TOIL payment (payment in lieu)A large uncashed TOIL balance is money sitting outside the payslip. If employment ends before the balance is taken or cashed, it should be paid out - but only if it was formally logged and agreed. TOIL payments in lieu are subject to PAYE and NI in the same way as overtime. Keep your own record and reconcile it with management records at least quarterly.
Civil Service alpha pension and how it applies to prison officers
HMPPS prison officers are members of the Civil Service alpha pension scheme unless they opted out or retain membership of an older legacy scheme. Alpha is a career-average defined-benefit scheme where each year's accrual is 2.32 percent of your pensionable pay for that year (indexed to CPI each April). Unlike a final-salary scheme, the years where you earn more are the most valuable. Your pensionable pay in alpha includes basic pay and the RHA, which is a pensionable allowance.
Employee contribution rates are tiered by pensionable earnings. For 2025/26 these were: 4.60 percent on earnings up to £34,799, 5.45 percent on 34,800 to £56,000, and 7.35 percent on 56,001 to £150,000. Verify whether the same thresholds apply for 2026/27 via the Civil Service Pension Scheme website or your payslip deduction notice, as the scheme can revise these. A Band 3 prison officer with basic pay of around 30,000 to £33,500 plus 20 percent RHA has total pensionable pay of roughly 36,000 to £40,200, placing them in the 5.45 percent tier under the 2025/26 rates. The pension deduction on the payslip will be that percentage of total pensionable pay (basic plus RHA), which explains why it looks larger than a simple percentage of basic pay alone.
Alpha was open to new entrants from 1 April 2015 and is now the default scheme. Officers who were members of the older classic, classic plus or premium schemes before 2015 may still be building up benefits under transitional arrangements, though litigation and legislative changes have affected this area. If you joined before April 2015, it is worth obtaining a statement from the Civil Service Pension Scheme to clarify which section applies to you and what benefits you have accrued. Do not rely on the payslip alone for pension entitlement questions - contact Civil Service Pensions through the Civil Service Pension Scheme website for a definitive view.
Deductions on a prison officer payslip
- PAYE income tax. Cumulative, against a 1257L code for most officers. With total pensionable pay plus any non-pensionable allowances, a Band 3 officer at the upper progression point may have total gross around £40,000 including RHA and UWH, meaning a portion will fall in the higher rate band. Check your year-to-date tax figure and compare with the basic rate and higher rate thresholds to confirm no over or underpayment.
- Class 1 National Insurance. At 8 percent on earnings between the primary threshold and the upper earnings limit (around £50,270), then 2 percent above. NI applies to all gross pay including allowances - basic, RHA, UWH and overtime. Market supplements are also earnings for NI purposes. Check that your NI category letter is A.
- Civil Service alpha pension contribution. Applied to pensionable pay (basic plus RHA). At the 5.45 percent tier for earnings between 34,800 and £56,000, a monthly pensionable pay of around £3,200 would produce a contribution of approximately £174. This reduces taxable income, so the net cost after basic-rate tax relief is around £140. Verify that UWH and market supplements are correctly excluded from pensionable pay if your scheme rules so require (check your Civil Service Pension Scheme member booklet).
- Prison Officers Association (POA) subscription. The POA is the recognised union for prison officers. Membership subscriptions are often deducted at source. The POA is not on HMRC's approved professional body list for tax relief purposes (unlike, say, a medical registration fee), so the subscription does not attract individual tax relief as a matter of course.
- Salary sacrifice schemes. Civil Service salary sacrifice schemes such as cycle to work, additional pension purchase (Additional Voluntary Contributions / AVC through alpha) or some childcare arrangements reduce gross before tax and NI. Any scheme you have signed up to should appear as a named line with the monthly amount shown.
Common prison officer payslip errors
The mistakes that genuinely show up on this role's payslips, and how to spot them.
Your prison officer payslip checklist
- 1.Check basic pay against the published HMPPS F&S band rate for your current pay point
- 2.Verify the RHA line equals exactly 20 percent of basic pay
- 3.Confirm total pensionable pay (basic plus RHA) matches the alpha contribution tier being applied
- 4.Review the UWH line matches the rate for your current establishment
- 5.Check overtime and payment-plus lines against your own record of additional hours
- 6.Confirm your tax code is 1257L cumulative and check whether any higher-rate liability is arising
- 7.Review your TOIL balance with your line manager and check it matches your own records
- 8.If you receive a market supplement, confirm it is not included in the pensionable pay figure
A worked example for a Band 3 prison officer
Take a Band 3 officer at the progression point of £32,000 basic pay for 2025/26. The RHA is 20 percent of 32,000 = £6,400 per year, or £533 per month. Adding a UWH allowance of, say, £3,000 per year (£250 per month at the officer's establishment rate), gross pay for a typical month is approximately 32,000/12 + 533 + 250 = 2,667 + 533 + 250 = £3,450. Total pensionable pay annually is 32,000 + 6,400 = £38,400, placing the officer in the 5.45 percent alpha tier.
Monthly alpha pension contribution: 5.45 percent of (38,400/12) = 5.45 percent of 3,200 = approximately £174. Taxable pay after pension: 3,450 minus 174 = £3,276. PAYE at 1257L: monthly allowance is £1,048, leaving £2,228 taxable at 20 percent = approximately £446. Class 1 NI on gross earnings above roughly £1,048: 8 percent of (3,450 minus 1,048) = 8 percent of 2,402 = approximately £192. Estimated net take-home: 3,450 minus 174 minus 446 minus 192 = approximately £2,638.
These figures are illustrative only, based on approximate 2025/26 pay rates and standard 2026/27 tax and NI parameters for a basic-rate taxpayer. They do not include any overtime, market supplement or TOIL payment. Your actual take-home depends on your specific band rate, progression point, establishment allowances and tax code.

Prison Officer payslip questions
What is the Required Hours Addition on my prison officer payslip?
The Required Hours Addition (RHA) is a pensionable allowance worth exactly 20 percent of your basic pay. It is built into Band 3 pay as recognition that the role regularly involves working unsocial and unpredictable hours as part of normal duties. It is not overtime - it is part of the standard contractual package for officers on the F&S structure. Because it is pensionable, it increases both your alpha pension contribution and your pension accrual.
Why is my Civil Service pension deduction larger than I expected?
Alpha pension contributions are calculated on your total pensionable pay, which includes both your basic pay and the RHA. A Band 3 officer with £32,000 basic pay has pensionable pay of £38,400 (including £6,400 RHA), and the 5.45 percent contribution tier applies to that higher base. The deduction is larger because it reflects a larger pensionable pay figure than basic pay alone.
Are prison officer market supplements pensionable?
Generally no. Market supplements are non-pensionable under current HMPPS arrangements - they should not be included in the pensionable pay base for alpha contribution purposes. If your payslip shows the supplement feeding into the pension deduction calculation, that may be an error. Check with payroll and, if necessary, your pension provider.
How does TOIL work for prison officers?
Time off in lieu (TOIL) accrues when you work beyond your conditioned hours. It can normally be taken as additional leave or, if agreed by management, cashed out as a payment-in-lieu. TOIL that is neither taken nor cashed out does not appear on the payslip as an asset. Keep your own log and reconcile it with management records periodically. If you leave employment with outstanding TOIL, you should be paid for it.
Does working at a private prison change my pay entitlements?
Yes, significantly. Private operators (Serco, G4S, Sodexo) run their own pay structures and pension schemes, which are separate from HMPPS F&S bands and Civil Service alpha pension. You will not accrue alpha pension while employed by a private operator. If you are transferring between public and private estate, seek advice on your pension transfer options before accepting the move.
What happens to my pay if I am promoted to Custodial Manager?
Promotion to Band 4 (Custodial Manager) puts you on the Band 4 pay range, which currently starts at around £34,000 basic pay. The RHA and UWH arrangements may differ at Band 4 - check the current HMPPS pay framework for the precise structure. Your alpha pension continues, and the higher pensionable pay means higher annual accrual. The promotion should take effect from the confirmed date, so check your next payslip and query any delay with HR.
Why has my take-home gone down after a pay rise?
A pay increase can push pensionable pay across an alpha contribution tier boundary (from 4.60 to 5.45 percent at £34,800, for example), or push total earnings closer to the higher-rate income tax threshold. The combination of higher pension contributions and a higher marginal tax rate on the extra earnings can mean net take-home rises by less than the gross increase - or, in unusual cases, very marginally less if the tier change is large. This is not an error; it is how tiered deductions work.
The bottom line
The RHA is the single most important line to verify. At 20 percent of basic pay it is the largest add-on, it is pensionable, and it must recalculate every time basic pay changes. An officer who joins at Band 3 entry, gets two increments and a pay award over three years, but whose RHA calculation was never updated, can be short by several hundred pounds a year in both cash and pension accrual. One check - divide the RHA by basic pay and confirm it is 0.20 - tells you whether the line is right or not.
