Prison officer disciplinary hearing: what to expect

In shortThe hearing puts the allegations to you, hears your response and decides on the balance of probabilities whether they are proven and what penalty is proportionate.

The hearing is the stage at which the employer, having investigated, puts the allegations to you, hears your response and decides whether to uphold them. It is not a criminal trial.

The hearing manager decides two things: whether the facts are established, and, if so, what sanction is proportionate.

Standard of proof

The balance of probabilities, which means more likely than not. The 2013 text adds that the more serious the allegation the more convincing the evidence needs to be, though not to the criminal standard. The same principle was set out in a 2026 tribunal judgment about an HMP Moorland dismissal.

Fairness test

The 2013 text says fairness is judged by reasonableness: grounds for believing misconduct took place, a sufficient investigation, a properly conducted procedure and a proportionate penalty.

Who holds it

Where possible, under the Acas Code, a different person should hold the hearing from the person who investigated.

In shortThe Acas Code says you should be notified in writing with enough information and the written evidence; the England and Wales notice period is not verifiable.

The Acas Code says you should be notified in writing with sufficient information about the alleged misconduct, and that copies of written evidence and witness statements should be included where applicable.

In the Moorland case, the investigation report was sent with the invitation, and the officer was told to read the Conduct and Discipline policy and warned that dismissal was possible.

The minimum notice period for a hearing in England and Wales is not publicly verifiable; the Scottish code requires at least 5 working days, but that is not your rule.

In shortYou can be accompanied by a colleague or a trade union representative or official; a solicitor or family member only if the employer agrees.

Choose your companion early. A POA rep who has handled hearings before is usually the natural choice, and the POA Legal Advice Scheme can provide assistance on disciplinary hearings subject to its approval and rules.

Its handbook says there is no initial advice for proceedings begun or under investigation before you joined or re-joined, but it is undated, so confirm the current rule. See POA representation in disciplinary cases and the right to be accompanied.

In shortThe outline is general, from the Acas Code and one published HMPPS example: the allegations are presented, you respond, the manager decides and writes to you.

The format below is a general outline based on the Acas Code and on the one published HMPPS example, not a description of the unpublished policy. There may be breaks, and the hearing may be adjourned.

1. Introductions and explanation of the process.
2. Presentation of the allegations and evidence, usually by the investigator or a management representative.
3. Your opportunity to ask questions through the hearing manager or directly, as agreed.
4. Your response, with your companion's support.
5. Witnesses, if any, and questions to them.
6. Closing remarks, including any mitigation.
7. Adjournment for the hearing manager to consider.
8. Decision and written outcome with how to appeal.

In shortPreparation is about understanding the evidence and presenting the facts clearly and truthfully, never lying, exaggerating or contacting witnesses.

Preparation is not about constructing a story. It is about understanding the evidence, getting the facts straight and presenting them clearly.

In shortIf the allegation is found proven you will usually be able to put forward mitigation before the penalty is decided; be realistic about the range of outcomes.

If the hearing manager finds the allegation proven, you will usually have a chance to put forward mitigation before the penalty is decided. The published 2013 text refers to proportionality of penalty, so context matters.

• Your record.
• The circumstances.
• Any pressures or health issues.
• Whether you took responsibility.
• Whether there were training or supervision gaps.
• The effect of the proposed outcome.

In shortYour outcome should be in writing with reasons and say how to appeal; the England and Wales appeal deadline is not published, so check the letter and diarise it.

General guidance lists the usual outcomes. The exact HMPPS list for England and Wales, who may issue each level and how long a warning stays live are not publicly verifiable.

For comparison only, the SPS Code uses verbal, written and final written warnings live for 6, 9 and 12 months, and the NIPS code up to 24 months. Do not assume those apply to you.

• No action.
• A written warning.
• A final written warning.
• Demotion.
• Dismissal.
• Another solution such as mediation.

In shortDismissal can lead to the Exclusions Register and vetting withdrawal but does not by itself forfeit Civil Service pension, and you may be able to claim unfair dismissal.

• Exclusions RegisterUp to 10 yearsOr indefinitely; appeal within 15 working days of notification
• Unfair dismissal qualifying period2 years6 months for dismissals with an effective date on or after 1 January 2027
• Tribunal time limit6 monthsFrom 1 October 2026, after Acas early conciliation

A dismissal for gross misconduct, or for misconduct that poses an underlying safety or security risk, can lead to a decision to place you on the Exclusions Register. Vetting status is withdrawn when an exclusion is reported, and a DBS referral must be considered where there is a risk to children or vulnerable adults.

Dismissal alone does not forfeit Civil Service pension; forfeiture is limited to narrow statutory cases.
