Prison Officer Pension Increases 2026: 3.8% and How It Works

In shortPublic service pensions in payment rose 3.8% from 6 April 2026, announced on GOV.UK on 26 February 2026 and set by a published CPI formula.

• Increase3.8%From 6 April 2026, for pensions in payment for a year
• Announced26 February 2026GOV.UK notice
• Based onSeptember 2025 CPIPensions in payment less than a year get a proportionate amount

GOV.UK published the Public service pensions increase 2026 notice on 26 February 2026. Pensions in payment for less than a year receive a proportionate amount depending on the number of months they have been in payment. The Civil Service Pension Scheme confirms the same: the 2026 pension increase is 3.8%.

The notice is mainly an administrative instrument for scheme administrators, alongside multiplier tables that account for increases from earlier years.

• It applies to pensions in payment.
• It is set by a published formula tied to CPI, and the scheme does not choose the figure.
• Different public service schemes apply the same rate, so a prison officer, a nurse and a teacher drawing a public service pension all see 3.8%.
• The CSPS says payslips and P60s showing the increase are distributed between late March and the end of May, with digital copies on the online member portal by 31 May.
• The new rate will normally first appear in the payment dated after the effective date. If you do not see it, raise it with the administrator, which is now Capita rather than MyCSP.

In shortEach April the previous September's CPI change is applied to pensions in payment: a formula, not a negotiation, and not linked to wages.

Each year the government takes the change in CPI between the previous September and the September before it and applies it as the pension increase the following April. For the 2026 rise it used September 2025 CPI.

The CSPS explains that if CPI shows an increase in prices, the pension increase is applied to pensions in payment in line with CPI. It is a formula, not a negotiation.

Timing

The effective date is the first Monday after 6 April for payment purposes in some sources and 6 April on the official notice, but the effect is the same: your annual pension is higher from April.

Compounding

Each increase is built on the previous year's pension, so successive rises multiply rather than add. A pension that has had four rises has had the product of those four, not the sum.

Prices, not wages

The CPI link means pensions rise when prices rise, protecting purchasing power, but it does not link to wages.

In shortThe last four increases were 10.1%, 6.7%, 1.7% and 3.8%, which compound to about 24% on a pension in payment throughout.

• Four increases combinedAbout 24%£10,000 becomes about £12,401
• Adding the percentages22.3%Compounding gives 24.0% instead

The table shows the last four annual increases as published by GOV.UK. They illustrate how volatile inflation has been. The percentages are the same for every public service scheme for pensions in payment for a full year.

The final column shows how a hypothetical £10,000 annual pension that had been in payment since before April 2022 would have grown if each increase was applied in sequence. It ignores any pension that started later (which got a proportionate amount in its first year), any lump sum commutation, and any tax.

A single weak year, like the 1.7% of 2025, matters less than the early high-inflation increases for people already retired, and more for people whose pensions began recently.

In shortA full-year pension of £8,000 rises by £304 to £8,304; a pension that started six months earlier gets roughly half, about £152.

The practical lesson for people planning retirement is that the increase is on your pension and the timing of the start date alters the first increase.

Retiring a few weeks before April gives a very small first increase, while having been in payment a full year before April gives the full rate. The difference is small compared with other decisions such as retirement age, but it is worth knowing when you receive your first adjusted payment.

In shortActive alpha members get no pension increase; instead each year's 2.32% accrual is revalued by CPI every April.

• April 2025 revaluation1.70%Example pension of £371.20 gaining £6.31
• April 2026 basis3.8%GB revaluation order not opened; check your statement
• Added each scheme year2.32%Of that year's pensionable earnings

If you are still working, you do not receive a "pension increase" because you are not drawing a pension. Instead your accrued alpha pension is revalued each 1 April by CPI (September to September) while you are an active member. The Civil Service Pension Scheme's alpha factsheet gives the April 2025 adjustment as 1.70%.

For April 2026 the CPI figure of 3.8% is the basis, and the Great Britain revaluation order was not one we could open, so check the statement figure rather than relying on us.

That is the career-average design: early years do not rise with your final pay, only with prices. For an officer on £30,000 pensionable earnings, a year adds £696 of annual pension, and that £696 then grows by CPI each April until retirement or leaving.

In shortA deferred pension is adjusted each year in line with prices, so it is not frozen in cash terms; your annual statement shows the figure.

If you have left with a deferred pension, the scheme guide says the preserved pension is adjusted each year in line with prices. In plain terms, the dormant pension tracks inflation in the same way.

The EPA part of a deferred alpha pension, if you bought one, is adjusted differently, depending on the EPA option chosen, so it needs separate checking.

We have not found a source that sets out, in one place, exactly how and when each April figure is applied to deferred alpha pensions. The GOV.UK notice speaks of pensions in payment, and the scheme guide speaks of price adjustment for preserved pensions.

In shortPay follows the Pay Review Body process and pensions follow a statutory CPI formula, so the two move on different calendars for different reasons.

For current officers the link matters in one way. Because alpha is career average and revalued by CPI, a pay rise above inflation increases the pension you build from that point but does not uplift the years already banked.

In a final salary scheme a pay rise would lift the pension for all previous service; in alpha it does not. That is one reason the pension from a long career can look modest next to final pay.

In shortThe increase applies only to pension in payment; it does not touch a lump sum, AVCs or partnership pots, tax, or your pension age.

Whether more of your pension income falls into a higher tax band depends on your overall income and the tax thresholds, which we do not cover here.

If you take a tax-free lump sum by giving up pension at £12 for every £1, the pension you keep, and so the cash value of each increase, is smaller. The pension lump sum guide explains the trade.

• It does not increase a lump sum once you have been paid it.
• It does not apply to an AVC pot or a partnership account, which are money-purchase arrangements whose value depends on contributions and investment returns.
• It is not a guarantee of a rise in every year: it is tied to CPI, and the scheme wording refers to an increase being applied if CPI shows an increase in prices.
• Pension income is taxable income in the year you receive it, so the headline 3.8% is before tax.
• It has no effect on your normal pension age or on the reduction if you claim early. The new GAD early-payment factors from 1 November 2026 may change early claim values, but they are separate from the annual CPI increase.

In shortCompare the new annual pension on your P60, payslip or statement with last year's, and ask the administrator in writing if it looks wrong.

The service has been disrupted since Capita took over, including payment delays for some new retirees; the Cabinet Office recovery plan said no one should suffer financial loss from administrative failures and Capita was developing an interest calculator for late payments. If a payment or increase is late, ask whether interest is due.
