Prison Officer Criminal Conviction: Job, Vetting and Pension

In shortDeclare all offences, cautions, reprimands and fixed penalties at vetting and renewal, and report charges, warnings and convictions in employment; the England and Wales reporting time limit is not published.

The Security Vetting policy (PSI 07/2014, AI 05/2014, PI 03/2014, revised 20 February 2025) requires applicants and staff to declare all criminal offences, cautions, reprimands and fixed penalties at vetting and renewal, in line with the Rehabilitation of Offenders Act 1974 (Exceptions) Order 1975 and criminal record filtering.

Non-disclosure by an applicant is likely to mean refusal, with no reapplication for 12 months. Because the Exceptions Order applies, spent convictions may be asked about, so do not assume an old matter is irrelevant without checking the exact question.

During employment, aftercare rules require you to report changes in circumstances:

• Annex F of the vetting policy includes involvement in criminal activity, criminal charges, warnings or convictions, disciplinary procedures and security incidents including employer sanctions for conduct misconduct.
• The Counter Corruption framework separately lists criminal convictions, cautions and investigations among matters to raise with your Local Counter Corruption Manager on the conflict of interest form.

In shortA charge, a caution and a conviction are different things, and conviction is not the only HR trigger: anything leading to a caution or prosecution, work-related or not, can be relevant.

People use the words interchangeably, and the differences matter. Each can trigger different HMPPS responses and different reporting duties.

For HR, the key point is that conviction is not the only trigger. The Exclusion framework says that anything leading to a criminal caution or prosecution, whether work-related or not, is relevant to safety, security and reputation.

HMPPS can also act on conduct without a criminal outcome, on the balance of probabilities, so an acquittal or no further action does not always end an HR process. See our guide to the interview under caution.

Arrest or interview under caution

An investigative step.

Charge

The CPS has decided there is enough evidence and it is in the public interest to prosecute.

Conviction

Follows a guilty plea or a finding of guilt at court.

Simple caution

An out-of-court disposal that follows an admission of guilt.

In shortAfter a conviction HMPPS can use a summary dismissal procedure, but dismissal still needs a fair reason and a fair process; the 2013 text is the last public wording.

The 22 July 2013 re-issue of the Conduct and Discipline policy says that after a conviction, an investigation may be unnecessary and a "Summary Dismissal Procedure" may be used (para 4.2). The policy is being rewritten, so this is the last public wording rather than a statement of current practice.

The Scottish and Northern Ireland codes treat conviction as potential gross misconduct, and the NIPS code limits who may decide summary dismissal after a conviction.

A conviction that arises from conduct at work, such as corruption or contraband, will usually also be gross misconduct. Our guides to corruption and bribery, contraband and mobile phones and misconduct in public office cover the offences. If you are suspended before trial, read about suspension.

• Summary does not mean unfair. Employment law requires a fair reason and a fair process; gov.uk says the employer must show a valid reason, have acted reasonably, investigated fully and been consistent.
• The Acas Code of Practice, which tribunals can use to adjust awards by up to 25 percent, expects employers to consider the circumstances.
• Where the conviction relates to something unconnected with work, the employer needs to consider its relevance to the role, and in a security role the connection is often easier to show.

In shortExclusion from HMPPS lasts up to ten years or indefinitely, can be local or national, can be appealed within 15 working days, and can lead to a DBS referral.

• LengthUp to 10 years or indefiniteIndefinite exclusion can be reviewed after ten years, then again after five more
• Appeal window15 working daysIn writing to Personnel Security Vetting, from notification

The national Exclusions Register records people excluded from working for HMPPS after dismissal for gross misconduct or for misconduct posing an underlying safety or security risk. Exclusion can last up to ten years or be indefinite.

After ten years you can apply to have an indefinite exclusion ended; if refused, you can apply again after five more years.

Exclusion can apply to one establishment or unit, a category of establishment, or nationally, and is decided by a Governor or Head of Unit or equivalent at Civil Service Grade 6 after a meeting with the person, which can happen in their absence.

When exclusion is reported, vetting status is withdrawn, and where there is a risk to children or vulnerable adults HMPPS must consider referral to the Disclosure and Barring Service.

• You can appeal in writing to Personnel Security Vetting within 15 working days of notification.
• Grounds include that the evidence was incorrect or incomplete, the exclusion is disproportionate, the length is excessive or other stated reasons.
• The appeal is decided by a Prison Group Director, Regional Probation Director or Deputy Director.
• The time limit is paused where a criminal investigation is running.
• Poor performance alone is not a reason to exclude.

In shortDismissal does not by itself forfeit your Civil Service pension; forfeiture needs specified convictions plus a Ministerial certificate, or recovery of losses caused by criminal, negligent or fraudulent acts connected with the job.

Many officers fear losing their pension automatically. The 2014 Civil Service pension regulations (regulations 165 to 169) say otherwise. Dismissal for misconduct does not by itself forfeit benefits. Forfeiture arises only in these cases:

• The person is convicted of specified Official Secrets Act offences and sentences add up to at least ten years.
• The person is convicted of an offence connected with their service as a public servant and a Minister issues a certificate that it was gravely injurious to the State or liable to lead to serious loss of confidence in the public service.
• Benefits are reduced to recover monetary obligations or losses caused by criminal, negligent or fraudulent acts connected with the employment.

In shortPrison officers can bring unfair dismissal claims; the general limit is now six months (from 1 October 2026) and qualifying service falls from two years to six months from 1 January 2027.

Prison officers are Crown employees who can bring unfair dismissal claims against the Secretary of State for Justice. Part X of the Employment Rights Act 1996 applies to Crown employment, and a 2026 tribunal judgment decided an officer's claim on its merits.

The tribunal asks whether the employer genuinely believed in the misconduct, had reasonable grounds and carried out a reasonable investigation, and whether dismissal fell within the range of reasonable responses.

Some dismissals need no qualifying period at all, including those linked to the following (section 108(3) of the 1996 Act). A conviction is rarely one of these, but if you believe the real reason was something else, say so to your adviser. See unfair dismissal tribunals and appealing a disciplinary outcome.

• Protected disclosures.
• Trade union activity.
• Certain discrimination-related grounds.
• Health and safety.
• Pregnancy or maternity.

In shortResigning does not stop an investigation, vetting report or exclusion decision; speak to a solicitor first and keep your key documents.

Some officers consider resigning when a conviction looks likely. Resignation does not stop HMPPS completing its investigation, reporting to the vetting team and deciding on exclusion, which can be made in your absence.

Counter corruption cases must be resolved after resignation as well. Resigning can also affect your options for appeal and tribunal claims. Speak to a solicitor before you resign; see resigning during an investigation.

Our misconduct response pack provides a structure for your timeline and questions for your representative. It is a tool for organising information, not legal advice, and it does not guarantee any outcome.

In shortSpent convictions can still be asked about under the Exceptions Order, and clearances run for seven to ten years but can be reviewed after a conviction; take advice in order.

• CTC and SC clearance10 yearsSeven if the person is under 21; directly employed staff
• Developed Vetting7 yearsAnnual reviews for SC and DV holders

The Rehabilitation of Offenders Act 1974 allows many convictions to become spent after a period, but HMPPS vetting uses the Exceptions Order 1975 and criminal record filtering, so you may still be asked about spent convictions and must answer the question that is actually put.

The vetting policy also says probation staff moving to other HMPPS prison or headquarters locations get checks on spent as well as unspent convictions. We do not give general advice on when a conviction is spent: a solicitor can tell you for your sentence.

A conviction, caution or other change can prompt a clearance review in between. Our guide on security clearance being withdrawn explains the process and how to ask for reconsideration.

1. Get legal advice about the criminal matter first.
2. Ask your POA representative about the employment and vetting position.
3. Make any declarations in the form advised.
4. Only then consider decisions such as resigning or applying elsewhere.
