The Public Interest Disclosure Act 1998 protects UK workers who make a 'protected disclosure' about certain types of wrongdoing at work — criminal offences, breaches of legal obligation, miscarriages of justice, health and safety dangers, environmental damage or the deliberate concealment of any of these. Protection includes automatic unfair dismissal (no qualifying period) + protection from detriment. This guide covers what counts as a qualifying disclosure, who to report to, the reasonable belief test + the compensation available if you're dismissed or victimised.

Disclosure of information you reasonably believe shows:
- Criminal offence
- Failure to comply with legal obligation
- Miscarriage of justice
- Health + safety danger
- Environmental damage
- Deliberate concealment of any of above
Must be in the public interest (not purely personal grievance).
Who to disclose to
Tier 1 — Employer (most cases):
- Line manager or designated whistleblowing officer
- Following employer's whistleblowing policy
Tier 3 — Wider public (very high bar):
- Where reasonable belief of continued cover-up
- Not for personal gain
- Same information could not be raised via tiers 1 or 2
Reasonable belief test
Belief must be honest + reasonable
Doesn't have to be proven true
Assessed at time of disclosure
Protection
Automatic unfair dismissal — no 2-year qualifying period
Protection from detriment — cannot be treated worse for disclosure
Employment tribunal within 3 months of detriment/dismissal
Compensation uncapped for detriment/dismissal
Common pitfalls
Raising as ordinary grievance (loses PIDA protection)
Personal grievance disguised as public interest
Wider disclosure without exhausting tier 1/2
Confidentiality clauses in settlement — these cannot silence future disclosures
In short
Whistleblowing protection = qualifying disclosure of specified wrongdoing, reasonable belief, public interest. Uncapped compensation.
Frequently asked questions
What if my employer retaliates for raising a concern?
That's actionable detriment under PIDA. File tribunal claim within 3 months of the detriment. Compensation uncapped.
Can I remain anonymous?
Employer's policy may allow anonymous disclosure. Protection strongest with named disclosure — anonymous disclosure harder to prove reasonable belief later.
Do I need proof of wrongdoing?
No — reasonable belief is sufficient. Doesn't have to be proven true.
Can settlement agreements silence whistleblowers?
No — any clause purporting to silence protected disclosures is void. Can settle past claims but not future disclosures.
