Appeal a Prison Officer Disciplinary Outcome (2026 Guide)

In shortThere is a right of appeal against any formal disciplinary decision, but the England and Wales detail sits in unpublished parts of PSI 06/2010, so your outcome letter is the key document.

The published part of PSI 06/2010 states there is a right of appeal against any formal disciplinary decision, and the same principle appears in the Acas Code, which says employees should appeal if they think action is wrong or unjust. This guide is about officers in England and Wales (HMPPS).

Scottish and Northern Irish officers have separate codes with published deadlines, covered below for comparison.

The detail of the England and Wales appeal stage, meaning who must hear it, how long you have and what the appeal can decide, sits in sections of the policy that are not public. So this guide does not give an E&W deadline.

What it gives you is what has been published in other documents and what two real appeals looked like in tribunal judgments.

In shortNo England and Wales disciplinary appeal deadline is published, so treat your letter as binding and ask HR in writing if it is silent.

For England and Wales we could not verify any published number of days to lodge a disciplinary appeal. That is a real gap, and we will not fill it from memory.

Treat the deadline in your outcome letter as binding and, if the letter is silent, ask HR in writing on the day you receive it, keeping a copy of the question and the reply.

To give you a sense of how varied the approaches are, the Scottish Prison Service Code (HR010/001, 2018) requires an officer to notify an intention to appeal within 5 working days and give grounds within 10 working days of the decision.

The Northern Ireland Prison Service Code (revised 2013) uses the same 5 and 10 working day pattern. Both documents carry old review dates, and neither applies to HMPPS.

In shortThe Acas Code asks for an impartial manager not previously involved; the E&W grade of appeal manager is not published.

The Acas Code says appeals should be dealt with impartially and, wherever possible, by a manager who has not previously been involved in the case. The published HMPPS cases are consistent with that.

The E&W rule on the grade of appeal manager is not published, and you should not assume that every appeal will be heard at that level.

In shortAppeals answer the grounds you give, so specific, document-backed grounds force specific answers; the Moorland officer used three.

Appeal grounds are the reasons you say the decision is wrong. These three map neatly onto the fairness test in the policy (grounds for belief, sufficiency of investigation, procedure and proportionality) and are a useful framework for any appeal.

• Dismissal was too severe a penalty
• The disciplinary proceedings were unfair and breached the rules of natural justice
• The original finding was against the weight of evidence

In shortTribunals look for a real opportunity to respond, not perfection: delay, missed reviews and a changed co-accused account did not defeat the published dismissals.

If you are thinking of raising procedure, it helps to know what has and has not been persuasive. A pattern emerges: tribunals look for opportunity to respond, not perfection.

Delay (Moorland)

The tribunal found the investigation 'undoubtedly took too long' but also found no evidence of prejudice beyond having a disciplinary investigation hanging over the officer, and that the delay did not affect the outcome. The tribunal also noted an officer's concern that colleagues had been discussing the investigation was not properly addressed by the employer, but did not affect the outcome. Keep records of such concerns and ask for them to be considered.

Suspension reviews (Belmarsh)

The policy required suspension to be authorised at a higher grade than was done and reviewed every 28 days (reviews happened at 29 to 40 day intervals). The tribunal found breaches but no unfairness flowing from them.

Missing CCTV (Belmarsh)

A missing CCTV recording of the landing outside the cell, which the officers said would have shown whether a witness could have seen into the cell, was found not to have undermined the process because the footage would not have shown inside the cell, the point could be and was tested at the hearing and the decision-maker weighed it.

A changed co-accused account (Belmarsh)

A senior officer changed her account at her own hearing; the governor adjourned, told the two officers in writing and reconvened so they could question her and make submissions. The tribunal held this was fair even though there was no transcript, because the key change was clear and they had the chance to respond.

In shortAn appeal is a structured challenge, not a rerun of your account: one short paragraph per ground, each pointing to a specific document.

An appeal is not a second chance to say everything again. The steps below follow the grounds approach and the practical requirements of both published cases.

1. Read the outcome letter twice and note the date, how to appeal, to whom and by when. If anything is missing, ask HR in writing.
2. Tell your POA representative or solicitor at once and, if you are a POA member, check the legal handbook on how to apply for assistance (see POA representation).
3. Ask for the documents you do not have: the investigation report, hearing notes or transcript, witness statements and any recording. Missing transcripts were one of the points raised by the Moorland officer.
4. Decide your grounds: weight of evidence, procedure, severity, new evidence. Write one short paragraph per ground, each pointing to a specific document or passage.
5. State the outcome you want: for example, that the finding be overturned, that a lesser sanction be substituted or that the dismissal be replaced by a lower penalty. Be realistic and be clear.
6. Add mitigation and evidence: Occupational Health and medical letters, references, service record, and anything that explains circumstances (without asking the manager to ignore the finding).
7. Ask to be accompanied by your union representative or a colleague, which you have a statutory right to at an appeal hearing, and think about whether you will make a prepared statement. See right to be accompanied.
8. Keep the tone calm. In both cases the decision-makers were assessed for credibility and for whether the officer showed insight. Allegations of bad faith or collusion without evidence did not succeed for the Moorland officer.
9. Keep a copy of everything you send, with proof of date, and diarise the date by which you expect a reply.

In shortYou have a statutory right to be accompanied, but whether you stay employed and on pay during the appeal is not known to be uniform, so ask in writing.

The Acas Code states workers have a statutory right to be accompanied at appeal hearings as well as disciplinary hearings. In Moorland the officer attended the appeal hearing on 28 April 2025 with a union representative; the decision was sent on 6 May 2025.

The tribunal also records that the effect of lodging an appeal was that her employment continued during the appeal process, ending on the date of the appeal outcome. We do not know that this applies to every HMPPS case, so ask in writing whether you remain employed and on what pay.

In shortA successful appeal can overturn a finding or reduce the sanction, but the published HMPPS tribunal cases involved appeals that were not upheld, and no success rate is published.

A successful appeal can overturn a finding, replace the sanction with a lower one or remove procedural defects, but the published HMPPS tribunal judgments we found involved appeals that were not upheld.

In Moorland the appeal was dismissed and employment ended on 6 May 2025; in Belmarsh both appeals were dismissed on or after 6 February 2023.

That tells you nothing about success rates, because those are cases that went on to tribunal and the selection is biased. HMPPS does not publish appeal statistics that we could find, and the Prisons and Probation Ombudsman confirmed in a 2025 Freedom of Information response that it holds no data on prison officers' disciplinary action.

The honest position is that appeals are worth making when you have a real ground and the evidence to support it, and are far less likely to succeed when they simply restate your account.

They also create a record that helps at tribunal: a decision-maker's reasons on a specific ground can show what the employer considered.

In shortIf the appeal fails, employment ends on the date your employer sets; that date starts the six-month tribunal clock, after compulsory Acas early conciliation.

If the appeal is not upheld, your employment ends, if it had not already, on the effective date set by your employer. That date starts or defines the tribunal clock.

• Tribunal: under the Employment Rights Act 2025 changes, the time limit for most tribunal claims is now 6 months from 1 October 2026, and Acas early conciliation is compulsory first and pauses the clock. In Moorland, early conciliation ran from 8 to 16 May 2025, just after the 6 May appeal outcome. Read the full explanation in unfair dismissal tribunal claims.
• Exclusion: if you were dismissed for gross misconduct or a safety or security risk, an exclusion decision may follow, and there is a separate 15 working day appeal. The wider picture is in the conduct and discipline hub. Our guide to what happens after dismissal explains the register, vetting, pension and references.
• Sanctions: for the outcomes that appeals try to change, see misconduct outcomes and sanctions.
• Pension: forfeiture is rare and narrow, but if it is ever proposed there is an appeal to the Civil Service Appeal Board under regulation 169 of the 2014 Regulations. See misconduct and your pension.

In shortThe most damaging mistakes are missing the deadline, appealing without grounds, attacking people rather than the decision and assuming the internal appeal stops the tribunal clock.
