Whistleblowing protections in the UK cover workers who report wrongdoing in the public interest. This guide explains what qualifies as a protected disclosure, how to raise concerns safely, and what to do if you face retaliation.
If you witness wrongdoing at work — fraud, health and safety violations, cover-ups — you may have both a moral and legal right to speak up. UK law protects workers who make disclosures in the public interest, but the protections are specific and need to be used correctly.
This guide explains who is protected, what counts as a protected disclosure, and what to do if your employer retaliates.
Whistleblowing protections come primarily from the Public Interest Disclosure Act 1998 (PIDA), which amended the Employment Rights Act 1996. The provisions are now found in sections 43A–43L and 47B of the ERA 1996.

To be protected, the disclosure must be made to an appropriate party:
If your disclosure is protected:
If your employer retaliates after a protected disclosure:
Interim relief (to maintain employment while the case proceeds) must be applied for within 7 days of dismissal — this is a tight deadline.
