Prison Officer Pay vs Inflation: Real-Terms Analysis 2026

In shortPay was ahead of prices in 2018 to 2020, behind in 2021 and 2022, and has since recovered part of the ground; your answer depends on your start date.

The calculation is simple, but the choice of dates and the choice of pay measure change the answer, so we state both every time.

Real terms

Pay after adjusting for prices. If your pay rises 4% and prices rise 10%, your pay buys about 5% less than it did a year earlier. If it rises 3.5% and prices rise 3.1%, you are about 0.4 percentage points ahead.

Our pay measure

The headline consolidated award recorded by the Prison Service Pay Review Body for the main officer grades, as set out in the award history.

Our price measure

The ONS Consumer Prices Index, all items: the CPI index (series D7BT, 2015=100) for cumulative comparisons and the CPI annual rate (series D7G7) for single years, both taken at March because pay awards take effect in April.

In shortThe real gap is positive in 2018 to 2020 and from 2023, and sharply negative in 2021 and 2022.

The table sets each headline award beside the ONS CPI annual rate in March of the award year and in March of the following year. The first tells you what prices had been doing when the award was set; the second what they did while you were living on it.

The 'real gap' is the headline percentage minus the CPI over the pay year, in percentage points. It is our arithmetic, labelled as such, and it excludes flat-cash and non-consolidated awards.

• Positive gap: 2018 to 2020 and 2023 onwards.
• Sharply negative: 2021 and 2022, when CPI over the pay year was 7.0% and 10.1% against a 0% freeze and a 4% award.
• The 2026 row is provisional: the pay year has not ended, so we use the 3.1% rate for the 12 months to August 2026, the latest ONS figure at the time of writing (the next release is due 21 October 2026).

In shortCompounded, pay was ahead in 2018 to 2020, behind from March 2021, and roughly level over the whole of 2018 to 2026.

Single years mislead, so the next table compounds. We use three windows, each starting with the March CPI index just before the first award in the window.

Why 'roughly level' is fragile

It is the product of two good years and a bad one, and it is sensitive to the start date. It also omits the Band 3 base-pay increases the PSPRB recommended in 2020 and 2022 (see the award history; we have not verified how they were implemented), and any Band 4 and 5 differences. Treat it as an order of magnitude, not a verdict.

In shortAn illustrative £30,000 salary in March 2021 with only the headline awards ends up short of the CPI-adjusted level.

Take an illustrative officer paid £30,000 in March 2021, and assume the headline consolidated awards were all they received (so no Band 3 extras, no progression, no change of hours). Applying 4%, 7%, 5%, 4% and 3.5% in turn gives £31,200, £33,384, £35,053, £36,455, £37,731 after the 2022, 2023, 2024, 2025 and 2026 awards respectively.

To have kept pace with CPI from the March 2021 index (109.4) to the March 2026 index (141.0), that same salary would need to be about £38,665. The illustrative figure of £37,731 is therefore about £934 short, or about 2.4% below the CPI-adjusted level. The numbers are an arithmetic illustration, not anyone's real pay.

In shortThe 3.5% award is slightly ahead of current CPI readings, but one year does not undo earlier losses.

• 2026/27 award3.5%Effective 1 April 2026
• CPI, March 20263.3%Award ahead by 0.2 points
• CPI, August 20263.1%Award ahead by 0.4 points; next release 21 October 2026

ONS reports CPI at 3.3% in March 2026, 2.8% in April, 2.6% in June, 2.9% in July and 3.1% in August 2026 (the latest figure at the time of writing). For Band 3 and Band 5 staff who also moved a pay point, the year's rise is larger; our 2026/27 pay rise guide quantifies it.

Band 2 is a separate case. The Band 2 spot rate rose by the 3.5% award on top of the National Living Wage uplift of 4.1% to £12.71 an hour from 1 April 2026.

The Band 2 base rose from £24,527 to £25,409 over the year on the published tables (that is 3.6% on our arithmetic, because the NLW-only step in the PSPRB table is £24,549, and the 3.5% applies on top of that).

In shortFive things move your real pay that the headline award does not show, so the real gap is a floor on the complexity, not a verdict on your pay.

Any real-terms analysis of a single percentage is incomplete. The five items below are the ones we know of.

The tax point is general and we have not modelled it per grade. For take-home figures by band, see take-home pay by band.

1. Pay point progression: Band 3 and Band 5 staff in post on 31 March who are not on formal poor performance procedures moved up one pay point on 1 April 2026, and the HMPPS objective is to reach the maximum within three years.
2. Band 3 structural increases, such as the £2,564 base uplift the PSPRB recommended from September 2020 and the £3,000 element in its 2022 recommendations, where implementation is not verified here.
3. Allowances: Payment Plus rose from £22 to £23 an hour in 2026 after being unchanged since 2016, a rise of 4.5% in cash terms, but CPI over the ten years from March 2016 to March 2026 rose 40.7% on the ONS index.
4. Non-consolidated payments, such as the £1,500 PEI payment, market supplements of £1,500 to £3,500 at 18 prisons, and the 2015, 2016 and 2018 one-offs, which do not raise base pay or, in the case of supplements, are non-pensionable and subject to gradual erosion.
5. Tax and National Insurance: the personal allowance is £12,570 in 2026/27, the same level as in 2021/22, so a pay rise that merely matches inflation pulls more income into higher tax bands; see prison officer tax and National Insurance.

In shortThe PSPRB does not set awards by formula: inflation is one input to a relative-position and forward-looking brief, not a catch-up guarantee.

Its terms of reference include 'the Government's inflation target', and in its 2026 report it says all staff 'continue to face pressure from the overall high cost of living, albeit against a background of slowly falling inflation over the last year'.

It says it takes account of that alongside pay settlement data, earnings growth and the labour market. It also states that its aim is, as a minimum, to maintain the relative market position of all staff in its remit group.

In shortYou can check your own pay against prices in a few minutes with your payslips and the ONS series.

You do not need our figures to check your own pay against prices. The method is the same one we use here.

1. Pick a start date, for example the March before the year you joined or your last promotion.
2. Note your annual base pay and allowances then, and now, from payslips or the pay tables in the pay bands guide. Compare like with like: base pay to base pay, or total including unsocial hours to total.
3. Divide your current pay by your starting pay and subtract one to get your cumulative rise.
4. Divide the ONS CPI index for the latest month by the index for your start month (series D7BT) and subtract one to get cumulative inflation.
5. Divide the first result by the second. Below one means you are behind prices; above one means you are ahead. Then adjust for tax and pension if you want a take-home view.
