Prison Officer Payslip Explained 2026: Every Line Decoded

In shortA payslip shows contracted pay including the 20% unsocial hours allowance, any extras, and four standard deductions; line names will differ from ours.

• Annual figure (inc UWH)£34,928Band 3 pay point 1, National, from 1 April 2026
• Gross a month£2,910.67Divided by twelve for payroll
• Take-homeAbout £2,282Our worked example

Prison officers in England and Wales are paid monthly. For most Band 3 officers the earnings side is simple: your contracted pay, which in HMPPS pay tables is quoted as one figure including the 20% unsocial hours allowance (UWH), plus anything extra such as Payment Plus hours, market supplement instalments or an allowance.

The reason people struggle is that the advertised salary and the payslip number look different. HMPPS publishes the annual figure including UWH and payroll divides it by twelve. Your payslip may show the base and the unsocial hours element on separate lines, or as one combined contracted-pay line.

• Income tax
• National Insurance
• Your Civil Service alpha pension contribution
• Repayment of a student or postgraduate loan, where it applies

In shortContracted pay and the unsocial hours allowance make the advertised figure and are pensionable; Payment Plus and market supplements are not.

Expect some or all of the lines in the table. Which ones appear depends on your band, contract hours and what you worked that month. The pension column matters because it decides how much pension you build up, and because pensionable pay also decides which contribution band you fall into.

Contracted pay and UWH

Together they make the figure HMPPS advertises. UWH is calculated at 20% of contracted hours for Bands 3 to 5 and is pensionable, according to HMPPS's evidence to the Pay Review Body, so it counts towards both pension accrual and the contribution band.

ACH and ACHP

If you have moved to 39 or 41 hours, you will also have Additional Committed Hours, shown as ACH or ACHP in the pay tables. Those attract UWH too. The 'P' version is the pensionable one; whether the non-P version is pensionable is only implied by the tables, so check your own contract.

In shortOn £34,928 a year, our worked example gives £133.89 pension, £345.86 income tax and £149.01 National Insurance a month, leaving about £2,282.

• Gross£2,910.67£34,928 a year (base £29,107 plus £5,821 UWH)
• Pension (4.6%)£133.89Taken before tax
• Income tax£345.8620% of £1,729.28 taxable
• National Insurance£149.01On gross pay
• Take-homeAbout £2,282Before any other deduction

1. Gross: £34,928 divided by twelve gives £2,910.67 a month.
2. Pension: because that is below £36,200, the 2026/27 alpha rate is 4.6% of pensionable earnings, £133.89 a month, assuming the whole of the £34,928 is pensionable (base and UWH both are).
3. Income tax is worked out after pension is deducted. With a standard 1257L code your monthly tax-free allowance is £1,047.50, so taxable pay is £2,910.67 minus £133.89 minus £1,047.50, which is £1,729.28. At 20% that is £345.86.
4. National Insurance is 8% of pay between the £1,048 a month primary threshold and the upper limit, applied to gross pay rather than pay after pension: (£2,910.67 minus £1,048) x 8% gives £149.01.
5. Take-home before any other deduction is about £2,282 a month.

In shortThe standard 2026/27 code is 1257L; if you see W1, M1 or X you are on an emergency basis, which new recruits often are on their first payslips.

Your tax code tells payroll how much of your pay is tax-free. The standard code for 2026/27 is 1257L, which reflects the £12,570 personal allowance. That works out at £1,047.50 a month, and payroll applies it cumulatively across the tax year, so a missed month of allowance in April catches up automatically.

Emergency codes such as 1257L W1 or M1 (and X variants) apply if payroll has no code for you, and they tax each pay period on its own, which often overcharges early in the job. GOV.UK sets out all of these in its 2026/27 employer rates page.

• New recruits are the group most likely to start on an emergency code, because the first payslip may be run before HMRC has given the new employer your code.
• If your first one or two payslips show significantly more tax than the worked example above, check your code on your personal tax account and with payroll.
• If you have been on emergency tax, the over-deduction should be recovered once the correct code applies, though the timing depends on the rest of the year.
• Do not guess: HMRC is the authority on your code, not this site.

In shortNI is calculated on gross pay while income tax is calculated after your pension comes out, so pension reduces your tax bill but not your NI bill.

• Employee NI8%Between £12,570 and £50,270 a year; 2% above
• Monthly NI threshold£1,048Primary threshold
• Employer rate28.97%1 April 2024 to 31 March 2027; 22.32% from 1 April 2027

National Insurance (NI) for employees in 2026/27 is 8% on earnings between £12,570 and £50,270 a year and 2% above that, according to GOV.UK. Payroll uses monthly thresholds. The detail officers often miss is that NI is calculated on gross pay, while income tax is calculated after your pension contribution comes out.

Alpha pension contributions are a percentage of pensionable earnings, by band. A Band 3 officer at pay point 3 on 37 hours has £36,778 of pensionable earnings, so pays 5.45%, while one at pay point 1 pays 4.6%.

The step between bands is a cliff for a whole year's earnings, so moving up a pay point can raise your contribution percentage on all your pay.

In shortPayment Plus (£23 an hour) and market supplements are non-pensionable, taxed and subject to NI, and each should appear as its own line.

• Payment Plus£23 an hourNon-consolidated, non-pensionable
• 8 hours of Payment Plus£184 grossRoughly £132 after 20% tax and 8% NI
• Bullingdon salary£38,428£34,928 plus a £3,500 supplement

Payment Plus is paid for specified duties outside your normal shift for that day, per the PSPRB. Because it is non-pensionable it does not build pension and does not count for your contribution band. It is, however, taxed at your marginal rate and subject to NI.

For how it works and which duties qualify, see Payment Plus explained, and for what your overtime really leaves, overtime after tax.

Market supplements are paid to Band 3 officers at 18 named prisons in 12 monthly instalments, and are non-pensionable. The HMPPS jobs page includes them in the quoted salary for those prisons. On your payslip the supplement should appear as its own line.

If it does not, ask whether your establishment is on the current list; the list is published in market supplements for prison officers.

In shortThe 2026/27 award was paid in June 2026 salaries backdated to 1 April, so that payslip may look heavy on tax because arrears are taxed in the month you receive them.

The 2026/27 award took effect on 1 April 2026, but payroll capacity meant HMPPS told the POA it would implement it in June salaries, with backdating to 1 April (POA CIRC 038, April 2026).

Arrears are taxed in the month you receive them, so a June payslip with a one-off lump can look unexpectedly heavy on income tax and NI even though the underlying rate has not changed. That is normal for any arrears payment, not an error.

• The new monthly pay.
• Arrears for April and May.
• Any pay point progression that applied from 1 April.

In shortBeyond tax, NI and pension you may see loan repayments and other schemes, but a deduction you do not recognise should be queried in writing.

The HMPPS employee package lists the season ticket loan and cycle to work among the benefits. GOV.UK sets out the loan thresholds for 2026/27.

• Student loan: 9% of pay above the plan threshold. Thresholds are £26,900 (Plan 1), £29,385 (Plan 2), £33,795 (Plan 4) and £25,000 (Plan 5).
• Postgraduate loan: 6% above £21,000.
• Season ticket loan repayment.
• Salary-sacrifice scheme such as cycle to work.
• AVC contribution.
• Trade union subscription.
