Prison officer whistleblowing: how to report and be protected

In shortHMPPS has a mandatory internal duty to report wrongdoing and a separate legal protection for protected disclosures; a report through a published HMPPS channel is normally both.

People often use 'whistleblowing' for any report about something wrong at work, but in HMPPS there are two systems with different rules.

The Civil Service Code adds a third strand: civil servants who have concerns should start by talking to their line manager, or if that would be difficult, to their department's nominated officers, and can report to the Civil Service Commission if they feel their concerns are not being addressed.

All three can apply to the same concern, so it helps to understand which route fits which kind of problem.

In shortReport through the intelligence system, your LCCM, the Counter Corruption Unit or the Integrity Hotline; you can be anonymous, but you will see little of what follows.

HMPPS strongly encourages people to give their name, because it makes investigation easier, but anonymity is available. If you are named, your identity is restricted to counter corruption staff unless you are needed as a witness, and a risk assessment is carried out first.

The framework also commits to protecting reporters from victimisation. Triage of corruption intelligence is within 72 hours according to the framework, though what that triage produces is not published.

Intelligence system corruption function

In prisons the primary route.

LCCM

Your Local Counter Corruption Manager, normally a Deputy Governor grade.

Counter Corruption Unit

The central unit you can report to.

Integrity Hotline

Independently run by Crimestoppers, with an online form that accepts anonymous reports.

National Counter Corruption Team

Allegations about senior managers go here.

• What happens next is largely not visible to you.
• The framework describes a criminal investigation taking primacy in corruption cases, with the police Senior Investigating Officer deciding priority and HMPPS consulting on any HR decision that could affect the criminal case.
• You may be asked for a witness statement, and you may not receive detailed feedback while an investigation is live.
• If you are not told what is happening, ask the person you reported to what you can expect and when, but do not press for details of an ongoing criminal investigation.

In shortA protected disclosure conveys information you reasonably believe is in the public interest and tends to show a listed wrong, such as a criminal offence or a danger to safety.

Section 43B of the Employment Rights Act 1996 defines a qualifying disclosure as any disclosure of information which, in the reasonable belief of the worker, is made in the public interest and tends to show one or more of the matters listed below.

Disclosure of information

You need to convey facts, not just make allegations or state an opinion.

Reasonable belief

You do not have to be right, but your belief must be reasonable.

Public interest

A personal grievance about your own contract is not enough unless it affects others. The GOV.UK guidance says that personal grievances do not qualify unless they are in the public interest, and that the wrongdoing can be past, present or likely future.

• A criminal offence has been, is being or is likely to be committed.
• A person has failed, is failing or is likely to fail to comply with a legal obligation.
• A miscarriage of justice has occurred, is occurring or is likely to occur.
• The health or safety of any individual has been, is being or is likely to be endangered.
• The environment has been or is likely to be damaged.
• Sexual harassment has occurred, is occurring or is likely to occur (added from 6 April 2026).
• Information tending to show any of those matters has been or is likely to be deliberately concealed.

In shortDisclosures to your employer or a prescribed person are the easiest to protect; wider disclosures such as to the media only count if the section 43G conditions are met.

GOV.UK keeps a list of prescribed persons, last updated on the page we read on 15 September 2026. When we searched it for entries relating to prisons, probation, the Ministry of Justice, the Prisons and Probation Ombudsman, HM Inspectorate of Prisons or Independent Monitoring Boards, we found no dedicated entry.

Bodies such as the National Crime Agency (for bribery and corruption), the Serious Fraud Office and the Health and Safety Executive appear for their areas. Check the live list before you rely on it, and take advice on which body, if any, fits your disclosure.

In shortGagging clauses cannot stop a protected disclosure, but the Official Secrets Acts and confidentiality duties still apply, so use the official channels first.

The practical effect is simple. Use the official channels first.

Do not take copies of documents, photograph screens or forward emails to a personal account without advice, because that can create a separate breach even where your concern is genuine, and it may include personal data about prisoners. If you need to show someone evidence, ask your adviser how to do it safely.

Prison Act 1952 s.40D also makes some unauthorised photography, recording and transmission inside a prison an offence.

In shortAfter reporting, do not discuss your suspicions beyond the report; false or malicious reports are misconduct, but honest, reasonable ones are what the system exists for.

A report made in good faith, on a reasonable belief and on factual information, is what the system exists for, even if it turns out to be mistaken. But if you report because of a personal dispute, or embellish what you saw, you risk both your protection and a conduct case.

The safest approach is to stick to what you personally saw, heard or know, record it in writing with dates, avoid speculation and avoid confronting the person concerned. If you feel unsafe, say so in your report; the framework describes wellbeing risk assessments and practical measures.

1. Write down what you saw or heard: dates, times, places, people and what was said, separating fact from opinion.
2. Note how you know it and whether anyone else was present or has the same information.
3. Decide the right channel using the table above. For security or corruption matters use the HMPPS channels; for bullying or discrimination consider IRRIS.
4. Make the report, keep a record of when and to whom, and ask what to expect next.
5. Do not discuss it with colleagues, investigate yourself, or confront the person concerned. Do not warn them, ask them to stop, or ask colleagues for support.
6. If you are worried about reprisals, get advice from your POA rep, a solicitor or Protect before or straight after reporting.

In shortReporters must not be victimised; record what happens, raise it, and act fast because the tribunal time limit is now six months from 1 October 2026.

• Tribunal time limit6 monthsFrom 1 October 2026 (it was three months before); Acas early conciliation first, which pauses the clock
• Dismissal for a protected disclosureNo minimum serviceSection 108(3) ERA
• Ordinary unfair dismissal2 years until 31 Dec 2026Six months for dismissals with an effective date of termination on or after 1 January 2027

HMPPS policy says reporters must not be victimised, and the law protects workers from detriment and dismissal for making a protected disclosure.

If you think you are being treated worse because of a report, such as being moved, excluded, given worse shifts, subjected to hostility, or disciplined, write down what happened, when, and who was involved.

Raise it with your manager or HR, or through the grievance route if it is bullying or harassment, and speak to your POA rep. IRRIS runs an interim grievance process for bullying, harassment, discrimination and victimisation complaints, decided by someone outside your line management.

The transitional rules for acts before 1 October 2026 are not something we have verified, so act urgently if the treatment began before that date.

In shortProtect, the POA legal advice scheme and a solicitor can each advise; have your notes and timeline ready before you ring.

Protect

A specialist UK whistleblowing charity with a free, confidential advice line for people worried about wrongdoing at work; it advises on whether a concern qualifies, which channel to use and what to do if you are victimised.

POA Legal Advice Scheme

For members, covering some work-related matters, though rule 19.8 of the version we read says there is no initial advice or assistance for proceedings started before you joined or re-joined. Check the current handbook.

A solicitor

Can advise on your particular circumstances.

In shortProtection depends on the substance and the route, not the word 'whistleblowing'; put facts in writing, use a channel and take advice.

Each of these can reduce protection or create a separate problem.

An email to your manager that sets out facts and says you are concerned about a possible criminal offence can qualify. A vague complaint that the place is badly run might not. Where possible, put it in writing, state facts, and say why you think it matters to others.

Remember that you are not alone and that reporting is the lawful and expected thing to do. HMPPS's own policy says failing to report corruption may itself be a disciplinary matter.
