Whistleblowing in the public sector

Whistleblowing means reporting wrongdoing at work that is in the public interest, such as a danger to patients or pupils, fraud, a crime or a cover-up. If your report counts as a protected disclosure under the Public Interest Disclosure Act 1998, it is automatically unfair to dismiss you for it, from your first day, and you are protected from other detriment such as being denied promotion. You must report to the right person: usually your employer, or a prescribed person such as a regulator.

What counts as a protected disclosure

To be protected, you must reasonably believe the information shows one or more of these:

• a criminal offence
• a failure to comply with a legal obligation
• a miscarriage of justice
• a danger to someone’s health or safety
• damage to the environment
• a cover-up of any of the above

You must also reasonably believe the disclosure is in the public interest. You do not have to be right, and you do not need proof. A reasonable belief based on information is enough, and a bare opinion is not.

Since 6 April 2026, the Employment Rights Act 2025 makes disclosures about sexual harassment explicitly qualify for whistleblowing protection.

In public services the obvious examples are unsafe staffing that puts patients at risk, safeguarding failures in a school, falsified records, misuse of public money, and breaches of infection control or health and safety law.

Who you can tell

How you make the disclosure affects whether it is protected.

Disclosures to your employer are the main route. That includes your manager, the person named in the whistleblowing or raising concerns policy, or a senior manager. In the NHS in England, each trust has a Freedom to Speak Up Guardian who can take concerns and help you raise them.

Disclosures to a prescribed person are also protected, if you reasonably believe the matter falls within their remit and the information is substantially true. Prescribed persons include regulators such as the Care Quality Commission, the Nursing and Midwifery Council, the Health and Care Professions Council, Ofsted, the Health and Safety Executive and HMRC. The gov.uk whistleblowing page links to the full list.

Wider disclosures, such as going to the media or an MP, are protected only in narrower circumstances, for example where you have already raised it internally or with a regulator and nothing was done, or where you reasonably fear a cover-up. The conditions are strict, and going public first carries real risk, so take advice before doing it.

Talking to a lawyer or your trade union for advice is itself protected.

How to raise a concern

Read your employer’s whistleblowing or raising concerns policy. Then:

1. write down what you saw, when, and who was involved, while it is fresh
2. raise it with the person or route in the policy, saying it is a whistleblowing concern
3. keep a copy of what you sent and any reply
4. if nothing happens, or the concern is about senior management, escalate in the way the policy describes or go to a prescribed person

Clinical staff also have professional duties. The NMC and HCPC codes expect registrants to raise concerns about patient safety, so staying silent can create its own risk.

Protection from detriment and dismissal

If you are dismissed because you made a protected disclosure, the dismissal is automatically unfair. There is no qualifying period of service, and compensation is not capped. You are also protected from detriment by your employer or colleagues, such as being moved, denied training, bullied or given unfair appraisals because you blew the whistle. Workers, agency staff and many trainees are protected, as well as employees.

The protection covers what happened because of the disclosure. If the main reason for action against you is something else, such as a separate conduct issue, it does not apply, so keep your own record.

Gagging clauses and settlement agreements

A clause in a contract or settlement agreement that tries to stop you making a protected disclosure is void. You can still report wrongdoing to your employer, a regulator or a prescribed person even if you have signed an agreement with confidentiality terms. In the NHS, settlement agreements must not stop staff raising patient safety concerns. The Employment Rights Act 2025 includes further restrictions on non-disclosure agreements, which the government lists for 2027 with no date set.

What happens after you raise a concern

Your employer should acknowledge your concern, investigate it in proportion to its seriousness, and tell you the outcome as far as it can without breaching others’ confidentiality. You may not hear everything, particularly if the concern leads to a disciplinary process for someone else.

A regulator will decide whether the matter falls within its remit and what action to take. Regulators often cannot tell you what they did. They may use your information alongside other evidence in an inspection, which is one reason the CQC and Ofsted take concerns from staff.

Whistleblowing and grievances

A whistleblowing concern is about a risk to others, and a grievance is about how you have been treated. If you have both, raise them separately. If you then suffer detriment for blowing the whistle, that can be the subject of a grievance. The grievance guide covers that process.

Getting help

Your union rep can advise before you raise a concern and support you afterwards. Protect, the whistleblowing charity, runs a free advice line. If you need to bring a claim, contact ACAS for early conciliation first. Since 1 October 2026 most tribunal claims, including whistleblowing detriment and dismissal, have a six-month time limit. An application for interim relief after a dismissal has a much shorter deadline, so act quickly. The trade unions guide lists the main public sector unions, and the CQC inspections guide explains the regulator’s role in health and care.
