Whistleblowing: making a protected disclosure

How to report wrongdoing in the public interest under PIDA 1998 — and claim the legal protections that come with it.

1. What is whistleblowing?

Whistleblowing is the legal term for reporting certain types of wrongdoing. If you report wrongdoing that qualifies as a "protected disclosure" under the Public Interest Disclosure Act 1998 (PIDA), you are legally protected from being treated unfairly or dismissed because you spoke up.

The critical distinction is between a grievance and a disclosure:

A grievance is about your personal situation

A complaint about how you have been treated — bullying, your contract, your workload. It is a private matter between you and your employer.

Whistleblowing is about the public interest

It concerns a wider danger or wrongdoing that affects others — other employees, clients, or the general public.

To be legally protected, your disclosure must be about one of the following six categories of wrongdoing — something you reasonably believe has occurred, is occurring, or is likely to occur:

  • Criminal offences — for example, fraud or theft.
  • Failure to comply with a legal obligation — for example, breaching data protection law.
  • Miscarriages of justice.
  • Danger to someone's health and safety.
  • Damage to the environment.
  • Covering up wrongdoing in any of these categories.

You do not need to prove the wrongdoing actually happened — you need a reasonable belief that it did, is, or will. But the disclosure must be in the public interest: a complaint that only affects you personally (like a dispute about your own contract) will not normally qualify.

2. Who should you report to?

To be protected, you must make your disclosure to the right person:

  • Your employer — directly, or through their whistleblowing policy. This is the safest first step.
  • A prescribed person or body — regulators approved for specific types of disclosure, such as the Health and Safety Executive (HSE) for safety issues, the ICO for data protection, or the Care Quality Commission (CQC) for care services.
  • A legal adviser — disclosures made while getting legal advice are protected.
  • Wider disclosure (MPs, media) is only protected in more limited circumstances — get advice first.
Going public is the riskiest route

Disclosing to the media or on social media is only protected if strict conditions are met — for example, you reasonably believed you would be victimised for raising it internally, or that evidence would be destroyed. Get advice from Protect (020 3117 2520) before any wider disclosure.

3. Your legal protections

If you make a protected disclosure, the law protects you in two ways:

Protection 1

Protection from detriment

Your employer must not treat you unfairly because you blew the whistle — no demotion, denial of promotion, exclusion, harassment, or any other disadvantage. A detriment claim has no minimum service requirement.

Protection 2

Automatic unfair dismissal

If you are dismissed because of your protected disclosure, the dismissal is automatically unfair — regardless of how long you have worked there. There is no two-year qualifying period and no cap on the compensation.

These protections apply to workers, not just employees — including agency workers, trainees, and some contractors. Confidentiality clauses (NDAs) cannot lawfully prevent you from making a protected disclosure.

4. How to make the disclosure strategically

  • Put it in writing: state clearly that you are raising a concern in the public interest, and set out the wrongdoing with dates, facts, and any evidence.
  • Use the magic words: phrases like "I believe this shows [a criminal offence / a danger to health and safety] and I am raising it in the public interest" anchor your disclosure to the legal categories.
  • Keep a copy of everything: the disclosure itself, the response, and how you are treated afterwards. Detriment claims live or die on this record.
  • Get advice before you disclose — Protect, the whistleblowing charity, runs a free, confidential advice line on 020 3117 2520.

5. What to do next

Report to a regulator

If the wrongdoing falls under a regulator's remit, a prescribed-person disclosure can be safer than going internal.
