Prison Officer Salary UK: A Complete Guide to Pay, Allowances and Comparisons

Prison Officer Salary UK: What You Need to Know

Understanding the prison officer salary UK is essential whether you are considering a career in the Prison Service or comparing a job offer against the national average. Pay varies widely depending on location, contracted hours, experience, and additional allowances. This guide uses the latest official data from the Office for National Statistics, the Prison Service Pay Review Body (PSPRB), and HM Prison and Probation Service (HMPPS) to give you a clear picture.

Starting Salaries and Regional Variations

The starting salary for a prison officer in England and Wales depends on the prison’s location and the number of hours you choose to work. All trainee officers begin on a 37-hour contract, but after training you can opt for 39 or 41 hours per week. The figures below include a 20% unsocial hours allowance, which is standard for shift work.

According to the official Prison and Probation Jobs website, national rate starting salaries (excluding market supplements) are:

• 37 hours: £33,746
• 39 hours: £35,875
• 41 hours: £38,003

In Inner London (prisons such as Brixton, Pentonville, Wandsworth, and Wormwood Scrubs), starting pay is significantly higher due to a market supplement:

• 37 hours: £39,493
• 39 hours: £41,984
• 41 hours: £44,474

Other London and South East prisons (e.g., Belmarsh, Feltham, High Down) offer starting salaries between £37,525 and £39,525 for 37 hours, depending on the specific supplement. The PSPRB’s 25th report (published in 2026) notes that market supplements of £2,000 and £3,500 are paid at ‘red’ and ‘red plus’ sites respectively, markedly improving the relative position of prison staff pay.

Allowances and Overtime

Beyond base pay, prison officers can boost their earnings through:

• Unsocial hours allowance: 20% of base pay, already included in the starting figures above.
• Market supplements: Additional payments for hard-to-recruit locations, ranging from £2,000 to £3,500 per year.
• Overtime: Often available, especially in understaffed prisons, and paid at enhanced rates.
• Pension: The Civil Service pension is one of the best in the UK, with defined benefits and employer contributions.

In Northern Ireland, Custody Prison Officers receive a Supplementary Risk Allowance of £4,110 (2024/25 rate), which pushes total compensation well above the median. Scotland has its own pay scales for Residential Officers, with wider ranges and higher maxima than the Band 3 grades in England and Wales.

Comparison with UK Median Earnings

The ONS Annual Survey of Hours and Earnings (ASHE) 2025 reports that median full-time gross annual earnings in the UK are £39,039. The mean (average) is higher at approximately £45,800. A prison officer on the national rate of £35,875 (39 hours) earns below the median. However, with a market supplement of £3,500, pay rises to £39,375, very close to the median. Inner London officers on 41 hours earn £44,474, which is above both the median and the mean.

The PSPRB’s pay comparator review (2026) found that when basic pay plus unsocial hours is considered, the salary range for Prison Officers (£33,746–£37,774) is above that of Police Community Support Officers and Firefighters, but below that of Residential Officers in Scotland and Custody Prison Officers in Northern Ireland. The review also noted that the Band 3 maximum in England and Wales did not exceed median earnings in any region in 2024/25, even with market supplements.

Take-Home Pay and Tax Considerations

Your actual take-home pay as a prison officer depends on Income Tax, National Insurance, and pension contributions. For the 2026/27 tax year, the personal allowance is £12,570, and basic rate tax (20%) applies to earnings up to £50,270. National Insurance (Class 1) is charged at 8% on earnings between £12,570 and £50,270. A prison officer earning £35,875 would have approximately:

• Income Tax: ~£4,661
• National Insurance: ~£1,864
• Take-home (before pension): ~£29,350 per year, or about £2,446 per month.

Important: Scotland uses different Income Tax bands. If you work in a Scottish prison, you will pay Scottish Income Tax, which has a starter rate (19%), basic rate (20%), intermediate rate (21%), and higher rates. This can reduce take-home pay compared to the rest of the UK for the same gross salary.

Future Pay Recommendations

The PSPRB’s 25th report (published in 2026) recommends a 3.5% increase for Fair and Sustainable Band 3 to 12 base pay from 1 April 2026. This is consolidated and pensionable. The National Living Wage also rose to £12.71 per hour from April 2026, which affects lower bands such as Operational Support Grades (OSGs). HMPPS’s written evidence for 2026/27 indicates that Band 3 officers on the national rate (39 hours) would see their base pay increase from £35,875 to approximately £37,131 if the recommendation is accepted.

How to Use This Information

When comparing a prison officer job offer, look beyond the headline starting salary. Consider:

• The number of contracted hours (37, 39, or 41).
• Whether a market supplement is included.
• The availability of overtime.
• Pension contributions and other benefits.
• The cost of living in the area (London pay may not go as far as national pay in a lower-cost region).

For broader context, check the UK Average Salary, which tracks median and mean earnings across all sectors. You can also explore salary data for other public sector roles.

Summary

The prison officer salary UK ranges from around £33,746 to £44,474 at entry level, depending on location and hours. While national rate pay sits below the UK median of £39,039, market supplements and overtime can close or exceed that gap. Inner London officers are particularly well compensated. Always verify the specific terms of any offer, and remember that Scotland and Northern Ireland have separate pay structures. For the most up-to-date figures, refer to official sources such as the ONS, PSPRB, and HMPPS.
