Read this first: three settings, three sets of rules

In shortBeing accompanied is three different rules: statutory at hearings and appeals, policy-based at investigation interviews, and a solicitor's right at police interviews under caution.

Being accompanied helps the process run well: it makes sure you understand what is said and have support in saying what you want to say. It is not one single right: in a prison discipline case you will meet at least three settings, and the rule differs in each.

This guide is about England and Wales (HMPPS), with comparisons for Scotland and Northern Ireland. We rely on the legislation, the Acas Code, the GOV.UK guidance, a third-party copy of the 2013 re-issue of PSI 06/2010 (partial) and two published tribunal judgments.

The current internal policy may differ, and it is being rewritten, so check the wording in your own invitation letter and ask HR for the policy in force. Nothing here is legal advice, and nothing should be read as encouragement to obstruct or delay a fair process.

Disciplinary or grievance hearing, and appeal hearing
A statutory right under section 10 of the Employment Relations Act 1999, which the Acas Code summarises.
Investigation interview
The HMPPS policy itself gives you the opportunity to bring a trade union representative or work colleague.
Police interview under caution
A different regime applies and the right is to a solicitor, which is outside this guide.

The statutory right: who can accompany you

In shortUnder section 10 you may choose a fellow worker, a trade union representative or a certified union official; in practice usually a POA branch representative or a trusted colleague.

Section 10 of the Employment Relations Act 1999 applies where a worker is required or invited by their employer to attend a disciplinary or grievance hearing and reasonably requests to be accompanied. The companion must be chosen by the worker and must be one of three kinds of person:

In practice, for a prison officer, the usual companions are a POA branch representative or a colleague you trust. A colleague has to be another worker of the same employer, and it is sensible to choose someone who is not a likely witness and who can keep the matter confidential.

Acas Code
Paragraph 14 describes the entitlement to be accompanied by a fellow worker, a trade union representative, or an official employed by a trade union; paragraph 15 says the worker must make a reasonable request; paragraph 28 adds that workers have a statutory right to be accompanied at appeal hearings.
GOV.UK disciplinary guidance
Gives the same three categories and says a family member, or a Citizens Advice worker, can attend only if the employer agrees or your contract says so.
  • A trade union official employed by the union.
  • A union official the union has certified in writing as having experience of, or having received training in, acting as a worker's companion.
  • Another of the employer's workers.

Investigation interviews: the policy protection

In shortAt an investigation interview, HMPPS policy (2013 copy, para 4.20) gives at least 48 hours' written notice and the chance to bring a union representative or work colleague; ask HR for the current wording.

The statutory right is aimed at hearings, and an investigation interview is a different thing. But the published part of the HMPPS Conduct and Discipline policy deals with it directly. The 2013 copy is partial and pre-dates later revisions, so ask HR for the current wording.

Before an interview, a line manager may meet you simply to establish the nature of an incident. The policy says the manager must tell you it is not a disciplinary meeting and must stop if it becomes clear a disciplinary investigation is needed.

Notice and rights (para 4.20)
An interviewee must receive at least 48 hours' written notice, must be told that the interview is part of a disciplinary investigation and that information may be used in proceedings, and must be told they may be accompanied by a trade union representative or work colleague and given reasonable time to arrange it.
Typed note (para 4.21)
A typed note of the interview must be given to you and your comments recorded in the report.
Co-operation (paras 4.22 to 4.24)
You must give all reasonable co-operation, you cannot be forced to answer but must be reminded that reasonable conclusions may be drawn if you refuse after proper warnings, and you need not answer a question if the answer might incriminate you.
Written answers (para 4.25)
You may ask to give written answers, which the investigating officer decides is reasonable, normally within five working days.
Union representatives (para 4.8)
If you are a union representative yourself, the senior union representative or a full-time official is told of the terms of reference and the outcome.

What a companion can and cannot do

In shortA companion may address the hearing, put and sum up your case and confer with you, but cannot answer questions on your behalf.

Section 10 and Acas paragraph 17 are specific. In practice that means you answer the decision-maker's questions yourself, with your companion helping you prepare, asking for breaks, putting points and questions where the process allows, and summing up.

The Moorland judgment gives a flavour of how hearings are run, set out below. In Belmarsh, the hearings were recorded, transcripts were available, the investigator presented the case, the use of force expert and witnesses gave evidence, and each officer questioned witnesses and gave evidence with a union representative present.

How the Moorland hearing ran

  1. Day 1Allegations explained

    She and her representative had the opportunity to put questions to the investigating officer, and she called a witness.

  2. Days 2 and 3Witnesses attend

    Witnesses interviewed during the investigation attended and she had the opportunity to put questions to them.

  3. ThenAllegations put to her

    The hearer put each allegation to her and asked questions to elicit her version of events.

  4. AfterwardsRepresentations

    She and her representative made representations going through the report and the evidence.

A companion can

  • Address the hearing to put and sum up your case.
  • Respond on your behalf to any view expressed at the hearing.
  • Confer with you during the hearing.

A companion cannot

  • Answer questions on your behalf.
  • Prevent the employer from explaining their case.

How to use your companion well

Meet beforehand to read the allegations and evidence and agree what you want to say. Agree signals for breaks. Ask your companion to take their own notes (a simple dated meeting log is enough, and the misconduct response pack can help you organise it), and to help you check the typed record afterwards.

Do not expect them to take over, and do not ask them to say something untrue.

If your companion cannot attend: the postponement rule

In shortIf your companion is unavailable, you can propose a reasonable alternative time within five working days of the original date and the employer must postpone.

The right would mean little if the employer could set a date that your companion cannot make.

Section 10 therefore provides that, if the companion you have chosen will not be available at the time proposed, you can propose another time that is reasonable and falls before the end of the period of five working days after the date originally proposed, and the employer must postpone.

The Acas Code, at paragraph 16, says the same: the employer must postpone the hearing to a time proposed by the worker, provided the alternative time is both reasonable and not more than five working days after the date originally proposed.

The right to postpone is not a licence to delay indefinitely. Acas also says that if a worker persistently fails to attend a meeting without good cause, the employer may decide on the evidence available.

  • If your companion's availability genuinely makes the first date impossible, propose a specific new date promptly and in writing.
  • If you need a different companion, say so.

The Moorland postponement

  1. 11 September 2024Interview rearranged

    The investigating officer wrote to inform the officer that her interview was being rearranged because her union representative was unavailable.

  2. 17 SeptemberInterview held

    It went ahead with the representative present.

  3. LaterA different representative

    Later meetings took place with a different union representative.

Making the request and what counts as reasonable

In shortAsk in good time, in writing, naming your companion and the meeting; a family member or adviser is a different request that the employer decides.

The Acas Code requires a 'reasonable request'. That means you should ask in good time, name your companion if you can and say which meeting you mean.

Many invitation letters already tell you that you may be accompanied, as in the Moorland judgment where the hearing invitation explained what the officer could do and the outcome letter was given in writing. If yours does not, ask HR in writing.

Reasonableness works both ways. An employer is not required to accept a companion who is a witness or who has a conflict of interest that would compromise the process, and a worker should not choose someone simply to obstruct.

Asking for a family member, a friend or a legal adviser to attend is a different request from the statutory right, and it is for the employer to agree.

Moorland: asking for a family member

  1. 23 January 2025The request

    The officer asked whether a family member could support her at the hearing in addition to her union representative, because of her mental health.

  2. ThenOccupational Health advice

    The employer referred her to Occupational Health, which advised that the hearing should go ahead promptly and that a family member should be allowed to accompany her.

  3. OutcomeAgreed

    The employer agreed that the family member could be present on the day, though not in the hearing itself but in a separate room to provide support during breaks.

Support for vulnerability, stress and reasonable adjustments

In shortThe process can adjust for stress and health needs, such as a break, an extra supporter or more time, if you ask in writing with supporting evidence.

A disciplinary investigation is stressful, and officers sometimes tell their managers things they would not otherwise share. The Moorland case shows what happened in practice:

The lesson is not that medical evidence will change the result. It is that the process can and does adjust, for example by allowing a break, an extra supporter, a different room or additional time, if you ask in writing with supporting evidence. You can ask your employer for similar adjustments in internal meetings.

Our guide to sickness absence management explains how health and attendance interact with discipline.

  • An Occupational Health assessment during the process recorded severe anxiety and depression symptoms, recommended that investigations be completed within a reasonable timeframe and that the officer be kept up to date, and recommended stress risk assessment and regular contact.
  • The care team attended meetings and supported the officer during the hearing.
  • The decision-maker considered the mitigation, but concluded it did not explain the behaviour.
  • The tribunal itself, in both published cases, adjusted for an ADHD diagnosis and dyslexia, including extra breaks and extra reading time, by reference to the Equal Treatment Bench Book.

Other settings: police, the Ombudsman and exclusion meetings

In shortPolice interviews, Ombudsman interviews and exclusion meetings follow different rules, and no published statement says who may accompany you at an exclusion meeting.

Police interview under caution
The right is to legal advice from a solicitor, and the POA's handbook says its scheme assists where you are interviewed under caution on a work-related matter. See interview under caution and POA representation.
Prisons and Probation Ombudsman or independent complaint investigation
HMPPS's Prisoner Complaints Policy Framework records that staff may be accompanied by a colleague or trade union representative, and that evidence they give is not admissible in disciplinary proceedings without their consent but can be disclosed to courts where the law requires. Check the current text with your representative.
Exclusion from working for HMPPS
The framework says the decision-maker meets the person before deciding on exclusion, but we could not find a published statement of who may accompany you at that meeting. The framework also says the decision can be made in your absence.

Scotland and Northern Ireland

In shortBoth devolved codes give a union representative or colleague at all stages, with no right to a legal representative in Northern Ireland; both carry old review dates.

Both codes carry old review dates, and their current status is not confirmed, so check with SPS or NIPS HR. Statutory rights under the Employment Relations Act 1999 apply across Great Britain, and Northern Ireland has its own equivalent legislation that we have not reviewed.

Scotland (SPS Code HR010/001)

  • Published 23 February 2018; gives employees an entitlement to a trade union representative or workplace colleague at all formal stages.
  • At least 5 working days' notice of a hearing; witnesses may be requested with 3 working days' notice; audio recording of gross misconduct hearings is expected.
  • Dismissal appeals go to an Internal Dismissal Appeal Board with a right to legal representation at the employee's own cost.

Northern Ireland (NIPS Code)

  • Professional Code of Conduct, revised September 2013.
  • Provides a right to a trade union representative or colleague at all stages but, expressly, no right to a legal representative at any stage.

A checklist before any meeting

In shortUse this list for every investigation interview, hearing or appeal: it protects your position and does not depend on the outcome.

  1. Read the letter. Does it say what kind of meeting it is, when, where, and who will be there? Does it say you may be accompanied and what the possible outcomes are?
  2. Contact your representative or choose a colleague. Confirm they can attend and have no conflict.
  3. If the date does not work, propose a specific alternative within five working days of the original date, in writing.
  4. Ask for the evidence you have not seen, and for the policy version in force. In both published cases the invitation enclosed the investigation report and told the officer dismissal was possible.
  5. Ask in writing for adjustments if you need them, with medical evidence, and tell your companion.
  6. Prepare with your companion: your account, the points you want to make, any witnesses you want to call and the questions you want to put.
  7. On the day, take notes. Afterwards, check the typed record promptly and send comments in writing.
  8. If you disagree with the outcome, diarise the appeal deadline from your letter (see appealing a disciplinary outcome).

Frequently asked questions

Who can I take to a prison officer disciplinary hearing?

By law, a fellow worker, a trade union representative or a certified trade union official. A family member or Citizens Advice worker is possible only if the employer agrees or your contract allows.

In a published 2025 Moorland case a family member was allowed to support the officer in a separate room during breaks on Occupational Health advice.

Can I be accompanied at an investigation interview?

The published 2013 copy of the HMPPS conduct policy says you should get at least 48 hours' written notice and may be accompanied by a trade union representative or work colleague, with reasonable time to arrange it.

Check the current policy with HR. The statutory right in section 10 is aimed at disciplinary and grievance hearings.

What can my companion say in the hearing?

They can put and sum up your case, respond to views expressed at the hearing and confer with you. They cannot answer questions on your behalf or stop the employer explaining its case. You answer the decision-maker's questions yourself, with your companion supporting you and helping you prepare.

What if my union rep cannot attend on the date offered?

You can propose another reasonable time within five working days of the original date and the employer must postpone.

In a published Moorland case an investigation interview was rearranged because the union representative was unavailable, and went ahead on 17 September 2024 with the representative present. Put your proposal in writing and name the new date.

Can I bring a solicitor to the disciplinary hearing?

There is no statutory right to a lawyer at the hearing, and the England and Wales policy on legal representation is not published. The Northern Ireland code excludes legal representatives at any stage, and Scotland allows legal representation at dismissal appeals at the employee's own cost. Ask HR, and take legal advice outside the room.

Can I be accompanied at my appeal hearing?

Yes. The Acas Code states workers have a statutory right to be accompanied at appeal hearings. In the published Moorland case the officer attended her appeal hearing with a trade union representative. Ask in writing for the appeal invitation to confirm who may attend and what notice you will receive.

Can a colleague who accompanies me be disciplined for it?

GOV.UK guidance says a companion cannot be disciplined for supporting you at a disciplinary hearing, and the statute gives a worker who acts as a companion paid time off for the purpose. A companion should keep the matter confidential and should not be a witness in your case, which could create a conflict.
