The formula: pay x 2.32% for every year of service
In shortEach scheme year adds 2.32% of that year’s pensionable earnings to your pension account, revalued by CPI each 1 April.
- Accrual rate2.32%Same for every grade (regulation 43)
- One year on £40,000£928Annual pension added
- Revaluation April 20251.7%CSPS alpha factsheet
- Revaluation April 20263.8%GOV.UK public service pensions increase page
The alpha regulations (regulation 43) credit your pension account each scheme year, which runs from 1 April to 31 March, with 2.32% of the pensionable earnings you received in that year. So a year on £40,000 adds £928 of annual pension.
The accrual rate is the same for every grade, so a higher band does not earn a better rate, it earns a larger base.
Each 1 April, the pension already in your account is revalued by CPI (September to September) while you remain an active member.
- There is no final salary link: a promotion in your last five years lifts only the pension earned after the promotion, which is why alpha pension explained matters if you are comparing yourself with a colleague retiring on classic benefits.
- You need at least two years of qualifying service to be entitled to a pension at all; with less, you may receive a refund of your own contributions.
What pay counts: basic pay, UWH and what is left out
In shortBasic pay and the 20% unsocial hours allowance count towards pension; Payment Plus and market supplements do not.
Pensionable earnings are basic pay plus allowances that the scheme manager treats as pensionable. The Prison Service Pay Review Body’s 2026 report and HMPPS written evidence state which ones count.
That is why the published Band 3 starting salary of £34,928 on a 37-hour contract, which includes UWH, is the sensible pensionable base for a new national-zone officer, not the £29,107 base pay figure.
What we could not verify
- Whether additional contracted hours on 39 to 41 hour contracts count in full, and which other allowances are pensionable, depends on the scheme manager’s decision under regulation 26.
- In the examples we use the published salary figures as if they were pensionable.
- Check your payslip and your Annual Benefit Statement to see what your administrator actually used.
What counts and what does not
Pensionable
- Basic pay.
- The Unsocial Working Hours allowance: 20% of contracted hours for Bands 3 to 5 (25% for Band 2 on a temporary basis).
- The Required Hours Addition at Bands 7 to 11.
Not pensionable
- Payment Plus, the £23 an hour payment for Bands 3 to 5, is non-consolidated and non-pensionable.
- The market supplements of £1,500 to £3,500 a year paid at 18 prisons.

Pension by salary and years of service (before revaluation)
In shortPension is simply pay x 2.32% x years; read the table as today’s-money anchors, not forecasts.
The table below uses the simplest possible method: pensionable pay multiplied by 2.32% and by the number of years, with the salary held level. It deliberately ignores revaluation.
That means it can be read as a figure in today’s money, which is a fair approximation if your pay rises by about the same rate as CPI revaluation, and an understatement in cash terms if pay and CPI both rise. The next section tests that.
- The years are complete scheme years of pensionable service, so a career from age 28 to 68 would be 40.
- Use the table to anchor expectations rather than to forecast.
- A rounded salary like £35,000 is close to the Band 3 pay-point-2 to pay-point-3 range, £40,000 to a Band 3 41-hour pay point or a Band 4 officer, and £50,000 is above the Band 5 top at 37 hours.
| Pensionable pay (level) | 10 years | 20 years | 30 years | 35 years | 40 years |
|---|---|---|---|---|---|
| £30,000 | £6,960 | £13,920 | £20,880 | £24,360 | £27,840 |
| £35,000 | £8,120 | £16,240 | £24,360 | £28,420 | £32,480 |
| £40,000 | £9,280 | £18,560 | £27,840 | £32,480 | £37,120 |
| £45,000 | £10,440 | £20,880 | £31,320 | £36,540 | £41,760 |
| £50,000 | £11,600 | £23,200 | £34,800 | £40,600 | £46,400 |
Arithmetic: for example £40,000 x 0.0232 = £928 a year, x 30 = £27,840. Rates are 2.32% per year from regulation 43(4). These are before tax, and State Pension is separate and not included.
What your contributions cost
In shortMember contributions cost 4.60% to 8.05% of all pensionable pay, taken before tax, while the employer pays a flat 28.97% until 1 April 2027.
- Up to £36,1994.60%From 1 April 2026
- £36,200 to £56,0005.45%From 1 April 2026
- Third band7.35%£56,001 to £150,000, from 1 April 2026
- Above £150,0008.05%From 1 April 2026
Member contributions are a percentage of all your pensionable earnings, set by band, and taken from your pay before tax. The rate applies to all pensionable earnings, not just the slice above the threshold, so crossing £36,200 raises the rate on every pound.
On £35,000 that is £1,610 a year, and on £40,000 it is £2,180.
The employer pays a flat 28.97% of pay until 1 April 2027, when the rate is due to fall to 22.32%, according to employer notices EPN743 and EPN749.
That employer cost is not yours, but it explains why alpha compares well with a private defined contribution plan, which the guide on prison officer pension versus a private pension tests.
| Pensionable pay | Rate | Cost a year | Pension earned that year |
|---|---|---|---|
| £30,000 | 4.60% | £1,380 | £696 |
| £35,000 | 4.60% | £1,610 | £812 |
| £40,000 | 5.45% | £2,180 | £928 |
| £45,000 | 5.45% | £2,452.50 | £1,044 |
| £50,000 | 5.45% | £2,725 | £1,160 |
Bands from CSPS (opened 3 October 2026). Contributions come out before tax, so take-home cost is lower.
Revaluation: why the pension grows between years
In shortRevaluation makes the cash total larger than the level-pay table; how much larger depends on CPI.
Because each year’s block of pension is revalued on 1 April for every year you stay in the scheme, the total in cash terms is larger than the level-pay table. How much larger depends on CPI.
The table below shows a £40,000 level salary with three revaluation assumptions. These are illustrative assumptions to show the mechanism, not forecasts: 0% (the tables above), 2% every year and 3% every year. All of these are cash figures, so compare them with prices at the time, not with today’s.
- Each year adds £928 at year end.
- At each following 1 April the pension already in the account is multiplied by one plus the assumed CPI rate.
- The first three columns hold pay level at £40,000, so they show revaluation alone.
- The last column is a more realistic combination: pay starts at £40,000 and rises 3% a year while the account is revalued at 2%.
| Years | 0% revaluation | 2% a year | 3% a year | Pay rising 3% a year, 2% revaluation |
|---|---|---|---|---|
| 10 | £9,280 | £10,161 | £10,638 | £11,593 |
| 20 | £18,560 | £22,548 | £24,936 | £29,711 |
| 30 | £27,840 | £37,647 | £44,150 | £57,156 |
| 40 | £37,120 | £56,053 | £69,972 | £97,811 |
Cash-terms, not today’s money. The last column starts at £40,000 and raises pay by 3% a year; compare against price levels, because the same pounds buy less in 30 or 40 years. Past revaluation: 1.7% in April 2025 and 3.8% in April 2026 (GB order not opened).
When you can take it: normal pension age and early retirement
In shortNormal pension age is the later of State Pension age and 65; taking alpha earlier (from 55, or 57 from 6 April 2028) cuts the pension permanently.
- Normal pension ageLater of State Pension age and 65Prison officers have no lower age in alpha
- Earliest early payment5557 from 6 April 2028, with a permanent actuarial reduction
- Retire at 60, NPA 680.644£17,929 a year on the illustrative £27,840 pension (2019 factors)
- Retire at 65, NPA 680.838£23,330 a year
You can take alpha pension early from the minimum pension age, which is 55 now and 57 from 6 April 2028, with a permanent actuarial reduction.
The last set of factors we could open (the 2019 GAD note, NI-hosted) is shown below. It is historic: the CSPS calculators page says new factors apply for retirement dates on or after 1 November 2026.
Treat the figures as an illustration of the size of the cut, which is large because alpha factors assume a long period of early payment.
Applying the factors to an illustrative £27,840 pension (30 years at £40,000): retiring at 60 with a normal pension age of 68 pays 0.644, so £17,929 a year. At 62 it is 0.712, £19,822; at 65, 0.838, £23,330.
- State Pension age
- 67 for people born between 6 March 1961 and 5 April 1977 and rises to 68 for those born from 6 April 1978, with a phased period for the year between.
- Pension age 60
- Public Service Pensions Act 2013 section 10 gives firefighters, police and armed forces a pension age of 60, and does not give it to prison officers. The Prison Officers’ Association is campaigning for 60, and a Commons debate on 11 November 2025 recorded engagement but no change; no decision was found as at 3 October 2026. See prison officer pension age.
| Retire at | Normal pension age 66 | Normal pension age 67 | Normal pension age 68 |
|---|---|---|---|
| 55 | 0.576 | 0.544 | 0.512 |
| 57 | 0.630 | 0.594 | 0.559 |
| 60 | 0.726 | 0.684 | 0.644 |
| 62 | 0.803 | 0.757 | 0.712 |
| 65 | 0.946 | 0.891 | 0.838 |

Part-time, career breaks, leaving early and the remedy
In shortPart-time work, career breaks, leaving early and the McCloud remedy each change the pension, and none comes with an uplift for lost years.
Because alpha is built on actual pensionable earnings, working fewer hours means a smaller pension, with no uplift for the lost years.
- Part-time and career breaks
- The CSPS working patterns guide states that part-time pension builds on actual earnings, a career break builds no pension and requires no contributions, and paid maternity and special leave counts while unpaid additional maternity leave and unpaid parental leave do not. The part-time and career break guide works through examples.
- Leaving early
- Leaving early with at least two years of service gives a preserved (deferred) pension. It is revalued with prices until it is paid, and can be claimed from 55 with a reduction or at normal pension age. Join again within five years and your old pension links up with the new service; a longer break makes it a separate pension. Our leaving early guide explains this.
- McCloud remedy
- If you were in classic, premium, classic plus or nuvos before moving to alpha in 2015 or 2022, the McCloud remedy usually lets you choose between legacy and alpha benefits for service between 1 April 2015 and 31 March 2022, when you retire. Legacy pension for that period may be paid from 60 or 65 and can be worth more. Your remediable service statement shows both; see the McCloud remedy guide. The up-to-date state of the exercise was not found, and Capita’s takeover on 1 December 2025 has caused delays.
Putting it together: a worked career from joining to 68
In shortCareer length drives alpha more than the rate does, as three worked careers show.
- Promoted over 40 years£38,7442.32% x £1,670,000 of career pay, today’s money
- Band 3 top for 40 years£34,130£36,778 x 2.32% x 40
- Early leaver£18,771Leaves at 50 after 22 years on £36,778: deferred pension in today’s money; payable from 68 unreduced or from 55 or 57 with a heavy cut
Take an officer who joins at 28 on Band 3 pay point 1 and works to State Pension age 68, a 40-year career. Assume 10 years at £35,000 (Band 3), 15 years at £41,000 (Band 4 or a longer contract) and 15 years at £47,000 (Band 5).
In today’s money before revaluation the pension is 2.32% x (350,000 + 615,000 + 705,000) = 2.32% x 1,670,000 = £38,744 a year. That is the real-terms ballpark of a career built to Custodial Manager level.
Now compare an officer who stays on £36,778, the Band 3 pay-point-3 level, for 40 years: 36,778 x 2.32% x 40 = £34,130.
- For the personal figure, use the alpha pension calculator or ask for a statement.
- Our guide to the pension statement explains how to read the numbers.
- The State Pension guide explains how the two fit together.
Frequently asked questions
How much pension does a prison officer get after 30 years?
In alpha, 30 years on £40,000 of pensionable pay builds £27,840 a year before CPI revaluation, from £40,000 x 2.32% x 30. On £35,000 it is £24,360 and on £50,000 it is £34,800. Revaluation, early retirement reductions, commutation and whether all your pay is pensionable change the real figure, so this is an illustration.
What is the prison officer pension accrual rate?
2.32% of pensionable earnings each scheme year in alpha, under regulation 43(4) of the Civil Service alpha regulations. The pension earned is added to your account and revalued by CPI each 1 April while you remain an active member. Older classic and premium sections use different accrual rates of 1/80 and 1/60 of final salary.
At what age can a prison officer retire on a full pension?
At alpha normal pension age, which is the later of State Pension age and 65. That is 67 for people born up to 5 April 1977 and 68 for those born from 6 April 1978, with a phased rise in between.
Prison officers have no lower age in alpha. You can retire from 55 (57 from April 2028) with a reduction.
Does overtime count towards my prison officer pension?
Not in any source we found. Payment Plus is described as non-pensionable, and market supplements are not pensionable either. The 20% unsocial working hours allowance for Bands 2 to 5 is pensionable. Whether other payments count is a decision for the employer, so check your payslip and Annual Benefit Statement.
How much does a prison officer pay into their pension?
From 1 April 2026 the rate is 4.60% of pensionable earnings up to £36,199, 5.45% from £36,200 to £56,000 and 7.35% above that up to £150,000. The rate applies to all your pensionable pay, not just the slice above a threshold. On £40,000 that is £2,180 a year, taken from pay before tax.
Is the prison officer pension index linked?
Yes. Active members’ accrued pension is revalued each 1 April by CPI, and pensions in payment increase each April: 3.8% from 6 April 2026 for pensions in payment a full year, pro rata for part years. Increases follow September CPI, so the cash amount can rise or flatten year by year with prices.
Does the pension include the State Pension?
No. The State Pension is separate and is paid by the Government at State Pension age, with its own qualifying rules. Alpha is a contracted-in scheme. We have not researched State Pension amounts for this guide, so use the GOV.UK forecast tool for yours. See the State Pension guide on this site.
