If you report wrongdoing and suffer for it, whistleblowing law protects you.

No 2-year qualifying period. Compensation is uncapped.

What counts as a protected disclosure — can I report anything?

A protected disclosure must show a qualifying disclosure: a criminal offence, legal obligation breached, miscarriage of justice, danger to health or safety, environmental damage, or cover-up of these. Personal grievances like bullying or discrimination alone are not protected unless they also reveal public interest wrongdoing.

Can I lose my whistleblowing protection if I was involved in the wrongdoing too?

No. The Public Interest Disclosure Act 1998 (PIDA 1998) protects you even if you were peripherally involved in the wrong. What matters is that you made a qualifying disclosure in the public interest to an appropriate person or body.

If my employer retaliates subtly — passed over for promotion, excluded from meetings — is that covered?

Yes. Protected detriment covers any adverse treatment: demotion, disciplinary action, being passed over for promotion, exclusion, bullying, contract termination. It does not need to be dismissal. Document everything with dates and witnesses.

I've been dismissed — how long do I have to claim?

3 months from the date of dismissal or the last act of detriment (ERA 1996 s.111). You must also go through ACAS early conciliation (source: acas.org.uk/early-conciliation). ET1 forms should be submitted within the 3-month window to protect your claim.

Can I make a protected disclosure anonymously?

The law is unclear on anonymous disclosures. If your employer cannot identify you as the source, they cannot retaliate against you. However, your identity may be needed later for a tribunal claim. Get legal advice on your specific situation.

What is interim relief and when is it available?

Interim relief is a rare but powerful remedy: the tribunal can order your employer to reinstate you immediately with full pay while your case proceeds. You must apply within 7 days of dismissal. It is only available if dismissal is solely for whistleblowing and you are likely to win.

Who bears the burden of proof — me or the employer?

Once you show a protected disclosure and a detriment, the burden shifts to your employer to prove the detriment was not because of the disclosure. This is a lower hurdle than ordinary discrimination cases.

Dismissed or treated badly for blowing the whistle? Protected disclosure gives you the right to bring an Employment Tribunal claim with no qualifying period.

If you report wrongdoing and suffer for it, whistleblowing law protects you.

UK whistleblowing protections — the Public Interest Disclosure Act

— allow you to bring an Employment Tribunal claim immediately if you are dismissed or treated badly for reporting crimes, breaches of law, health and safety dangers, or cover-ups.

What is a protected disclosure?

A protected disclosure is a qualifying disclosure made to an appropriate person. You must disclose information that tends to show one of the following in the public interest:

A breach of a legal obligation
A miscarriage of justice
Danger to the health and safety of any individual
Damage to the environment
A cover-up of any of the above

You can disclose to your employer, a legal adviser, a regulator, an MP, or in limited circumstances to the public or prescribed persons (depending on the issue).

What is NOT a protected disclosure?

Personal grievances:
Bullying, discrimination, or unfair treatment alone are not protected unless they also reveal public interest wrongdoing.
Deliberately false allegations:
If you make a disclosure knowing it is untrue, you lose protection.
Disclosures made in bad faith:
If your motive is entirely malicious (revenge, competition), a tribunal may decide you had no public interest intent.

What detriments are protected against?

Once you have made a protected disclosure, your employer must not treat you badly. Protected detriments include:

Demotion or reduced pay
Being passed over for promotion
Exclusion from work, meetings, or projects
Being subjected to bullying or harassment
Having your contract terminated

Protection extends to employees and workers (a wider category including casual and gig workers).

Who is covered by whistleblowing law?

Anyone with a contract of employment.
Broader definition including agency workers, zero-hours workers, self-employed in some circumstances.
Specific protections apply.
Protected in limited circumstances (eg. if you are not offered a job because you disclosed at interview).

How to bring a whistleblowing claim

Step 1: ACAS Early Conciliation (mandatory)

Before filing at tribunal, you must contact ACAS within the 3-month time limit.

ACAS will try to help you and your employer reach a settlement. This takes up to one month (can be extended by one month by agreement).

Step 2: File ET1 (within 3 months)

Submit your ET1 claim form to the Employment Tribunal within 3 months of the dismissal or last detriment.

Include full details of the disclosure, the date, to whom it was made, and the detriment suffered.

Step 3: Compensation

If you win, compensation is uncapped and includes: back pay from dismissal/detriment to award, future loss of earnings, injury to feelings, aggravated damages in egregious cases. Interim relief (reinstatement with pay) is available if you apply within 7 days of dismissal and are likely to win.

Document everything:
Write down the date of the disclosure, to whom you made it, and what you said. Contemporaneous notes are powerful evidence.
Document the detriment:
Keep records of any adverse treatment — emails, disciplinary letters, promotion denials, meeting exclusions. Include dates and context.
Establish a timeline:
Show the sequence: disclosure → detriment. The closer the timing, the stronger the causal inference.
Employer's other reasons:
Employers often claim they dismissed you for a different reason (capability, conduct, redundancy). Your evidence must show this is either false or merely a pretext.
If others knew about the disclosure or witnessed the detriment, their accounts strengthen your case.
