Prison Officer Misconduct Outcomes and Sanctions (2026)

In shortPSI 06/2010 governs your case but is not on GOV.UK, so every point here is tied to a named source and unknowns are flagged.

This guide is about England and Wales (HMPPS). Scotland (SPS) and Northern Ireland (NIPS) have their own published codes, summarised in a later section so you can see how different the rules are. Prison Officer Pay is independent of HMPPS, the Ministry of Justice and the POA, and nothing here is legal advice.

The policy that governs your case is not on GOV.UK. PSI 06/2010 Conduct and Discipline appears on the official Prison Service Instructions index as extant but not published, with its latest logged revisions on 13 January 2020 and 7 May 2025.

• The only public full text we could open is a third-party copy of a 2013 re-issue that stops part-way through the investigation chapter.
• The sections on suspension, hearings, penalties and appeals are not publicly verifiable, which is exactly where the questions in this guide live.
• If you are facing a hearing, your establishment HR team can give you the policy, and your POA representative will know how it has been applied locally.

In shortThe policy's primary objective is improvement, not sanction, and the penalty must be proportionate; gross misconduct can end employment at a first finding.

The published fragments of PSI 06/2010 set out the approach before any list of penalties. The purpose of the procedure is to resolve misconduct at an appropriate level and as speedily as possible, fairly and openly. Its primary objective is stated to be 'to encourage improvement in an individual rather than impose a disciplinary sanction'.

In practice a manager is expected to consider whether a conversation, coaching, training, mediation or a performance process would deal with the problem before reaching for formal action.

Proportionality

Where sanctions are decided. Two officers can commit the same act and receive different outcomes because the circumstances, history and attitude differ, and the published tribunal cases below show exactly that happening.

Standard of proof

The balance of probabilities, with a higher level of satisfaction expected the more serious the allegation, though not the criminal standard of 'beyond reasonable doubt'. A Moorland tribunal judgment published in 2026 quotes the same principle from the policy.

No dismissal for a first breach

The policy says no one will be dismissed for a first breach of discipline except in gross misconduct cases. For ordinary misconduct the expected route to dismissal runs through a sequence of earlier sanctions, but gross misconduct can end employment at the first finding.

In shortThe Acas Code gives the general spectrum, but HMPPS's own level names, who may impose each and how long each stays live are not public.

General employment practice, reflected in the Acas Code, recognises a spectrum. What the Acas Code cannot tell you is HMPPS's own ladder: the names of each level, who is authorised to impose them, and how long each stays live.

That detail was not in any public document we could open. The table sets out what is verified and what you must ask for.

• A confirmed case of misconduct usually attracts a written warning (paragraph 19 of the Code).
• Where the conduct has had, or is liable to have, a serious or harmful impact on the organisation, an employer may go straight to a final written warning even for a first offence (paragraph 20).
• Some acts are gross misconduct, so serious that they may justify dismissal without notice for a first offence, though a fair process must still be followed (paragraphs 23 to 24).

In shortAn advice and guidance letter is not a formal sanction, but it is a documented marker that can be used later.

The published part of the policy says not every breach leads to formal action. A line manager may meet a member of staff solely to establish the nature of an incident, must say it is not a disciplinary meeting, and must stop and consider a formal investigation if it becomes clear one is needed.

Managers keep brief notes and record their decision locally, but the notes are not to be placed on the personnel file.

A written 'advice and guidance' letter sits in an important grey zone. The Moorland judgment shows how it was used.

• Informal does not mean invisible: read an advice and guidance letter as a documented marker.
• It is usually kept for a reason, it can be referred to later, and any assurance you gave in it will be remembered.
• Ask your POA representative how such letters are held locally and whether you can add a response to the record.

In shortNo public live-period figure exists for England and Wales; Scotland and Northern Ireland publish theirs, but they are not the E&W rule.

Officers often ask how long a warning stays 'live'. For England and Wales we could not verify a public figure, so we will not give one. The question matters because a live warning is typically what turns a later, otherwise modest, finding into something more serious.

In shortTwo public judgments show HMPPS decision-makers using final written warnings, promotion bars and demotion below dismissal, but they are single cases, not rules.

Two public tribunal judgments, both involving the Secretary of State for Justice as employer, give a rare window into outcomes below dismissal. They are single cases and are not rules, but they show the type of penalty HMPPS decision-makers have used.

Belmarsh (Dixon and Smith, heard December 2023)

A hearing governor found an allegation of assault on a prisoner proved against two officers and dismissed them for gross misconduct. For a senior officer involved in the same incident who changed her account at her own hearing and accepted the allegation of excessive force, the governor imposed a final written warning and a bar on eligibility for promotion for two years. The difference turned partly on what the governor saw as an integrity issue: she found the two dismissed officers had assaulted the prisoner and had denied it through the disciplinary process.

Moorland (Hayes, judgment dated 21 August 2026)

The tribunal heard evidence about two other officers involved in sexual-nature incidents who had not been dismissed. One, a one-off incident that the officer admitted and for which she was remorseful, resulted in a final written warning and what the judgment calls a 'double demotion'. The other, found to be messing around that went too far with no proof of sexual intent, was downgraded to a role in which he would have no further contact with the colleague.

In shortGross misconduct can justify dismissal without notice for a first offence, but a fair process is still required, and the employment end date is not always the decision date.

For gross misconduct the Acas Code recognises that dismissal without notice may be justified for a first offence, but that a fair disciplinary process should always be followed.

GOV.UK's dismissal guidance also notes that employers can dismiss immediately in some situations, such as for violence. In both published HMPPS judgments the sequence was the one listed below.

1. Investigation.
2. A hearing at which the officer was told that dismissal was a possible outcome.
3. A written outcome.
4. An appeal.

In shortThere is no published scoring matrix, but the judgments show recurring factors: seriousness, repetition, honesty and remorse, mitigation and consistency.

There is no published scoring matrix. What the tribunal judgments reveal is a set of recurring considerations. Understanding them helps you prepare mitigation in an honest, useful way.

Seriousness

Comes first. In the Belmarsh case the judge said that assault on a prisoner is on any view serious misconduct. In the Moorland case the governor concluded that one incident amounted to sexual assault and the others were overtly sexual, and that dismissal was the appropriate sanction because of the nature of the misconduct.

Repetition after warning

The Moorland officer's behaviour continued after verbal reminders and after a written advice and guidance letter.

Honesty and remorse

Count heavily. The tribunal in Moorland noted that the officer denied most incidents and did not demonstrate genuine remorse or any willingness to change behaviour, while the comparators who admitted fault and apologised kept their jobs.

Mitigation

Formally considered, but it does not erase the finding. The Moorland governor considered the officer's mental health and personal circumstances, took Occupational Health advice about the hearing, and still decided they did not explain the behaviour.

Consistency

An employer is expected to treat similar offences consistently, but a tribunal will only find unfairness if two cases are truly parallel and the employer's assessment of the differences was not one a reasonable employer could make.

In shortA sanction can affect vetting reporting, promotion and, for gross misconduct, the Exclusions Register, but dismissal alone does not forfeit a Civil Service pension.

Vetting

HMPPS vetting aftercare rules list the changes in circumstances that individuals must report, and the list includes disciplinary procedures and security incidents including employer sanctions for code-of-conduct misconduct. If you have been given a formal sanction, check with your line manager or the vetting team whether and how it must be reported, and take your POA representative's view. Vetting and clearance are covered in our guide to security clearance being withdrawn.

Promotion

The Belmarsh warning came with an explicit two-year promotion bar, and the NIPS code in Northern Ireland lists a promotion ban of up to two years. Whether an unspent warning affects a promotion board in England and Wales is not published; ask HR and read our promotion and discipline guidance.

Exclusions Register

Dismissal for gross misconduct, or for misconduct that poses a safety or security risk, can lead to the Exclusions Register.

Pension

A separate question. Dismissal for misconduct does not by itself forfeit a Civil Service pension; forfeiture is limited to specific convictions and certain debts, covered in misconduct and your pension.

In shortWhat you do before the decision is announced matters more than what you do afterwards; each step is about giving the decision-maker the full picture.

The steps below are drawn from published policy and from what tribunals have examined. None is a tactic to avoid accountability; each is about making sure the decision-maker has the full picture.

1. Ask HR for the current Conduct and Discipline policy and read the penalties and appeals sections, not just the investigation chapter.
2. Contact your POA representative now if you have not already, and read the POA legal handbook for your nation so you know what assistance covers and how to apply (see POA representation).
3. Ask in writing what outcomes the decision-maker can impose and whether dismissal is a possible outcome. Hearing invitations should say so, as they did in both published cases.
4. Gather mitigation evidence: Occupational Health letters, medical reports, character references from people who know your work, records of previous good service, and any evidence that supports the account you gave.
5. Think honestly about what you accept happened. Tribunals noticed remorse and insight, and also noticed denial that the evidence contradicted. Your representative can help you say what you can truthfully say.
6. Look for genuinely comparable cases through your representative. Quote specifics, not rumours, and understand that the decision-maker may say the cases differ.
7. Plan for the outcome letter: diarise the appeal deadline the day you receive it (see appealing a disciplinary outcome).

In shortThree beliefs are only partly true: the neat warning ladder, 'informal cannot be used later', and 'a long investigation makes dismissal unfair'.

In Belmarsh, the tribunal found breaches of the suspension policy (the wrong grade authorising the suspension and review intervals of 29 to 40 days instead of 28) and still found the overall process fair. Process failures matter and can be raised, but they rarely win a case on their own.
