Whistleblowing at Work

EmploymentLast reviewed: 1 April 20257 min read

Whistleblowing means disclosing information about wrongdoing in your workplace to the relevant authority. The Public Interest Disclosure Act 1998 (PIDA) protects workers who make "qualifying disclosures" in the public interest from dismissal or detriment. Understanding these protections ensures you can speak up safely.

Key points

  • A qualifying disclosure must relate to specific types of wrongdoing including criminal offences, health and safety risks, or a miscarriage of justice.
  • You must reasonably believe the disclosure is in the public interest — not solely for personal gain.
  • You are protected from dismissal and detriment regardless of your length of service.
  • Disclosures must be made to the right person or body — internal disclosures are protected; external disclosures require additional conditions.

What Is a Qualifying Disclosure?

A "qualifying disclosure" under the Employment Rights Act 1996 (as amended by PIDA) is information that, in the reasonable belief of the worker, tends to show one or more of the following:

  • A criminal offence has been, is being, or is likely to be committed
  • A person has failed, is failing, or is likely to fail to comply with a legal obligation
  • A miscarriage of justice has occurred, is occurring, or is likely to occur
  • The health or safety of any individual has been, is being, or is likely to be endangered
  • The environment has been, is being, or is likely to be damaged
  • Information tending to show any of the above has been, is being, or is likely to be deliberately concealed

Since 2013, disclosures must also be made in the public interest — not just for private benefit. You must reasonably believe both that the information is true and that making the disclosure is in the public interest. "Reasonable belief" does not mean you have to be right — you are protected even if the information turns out to be incorrect, provided you genuinely believed it.

Who Is Protected and How?

Protection under PIDA covers workers (not just employees) — including agency workers, trainees, and some self-employed contractors. This is wider than most other employment rights, which often only cover employees.

A worker who makes a qualifying protected disclosure is protected from:

  • Dismissal: Dismissal for making a protected disclosure is automatically unfair, regardless of length of service.
  • Detriment: Being subjected to any detrimental act by the employer or by colleagues (following a 2017 court ruling) because of the disclosure — including being overlooked for promotion, excluded from opportunities, or subjected to hostile treatment.

For the disclosure to be protected, it must be made to an appropriate person. Internal disclosures to your employer or a responsible person within the organisation are automatically protected. External disclosures to a prescribed body (such as the Health and Safety Executive, HMRC, or the Financial Conduct Authority) are protected provided you reasonably believe the relevant regulatory body is the appropriate recipient. Disclosures to the media have higher thresholds.

What to Do Before and After Whistleblowing

Before making a disclosure, consider:

  • Does the information relate to one of the qualifying categories of wrongdoing?
  • Do you genuinely and reasonably believe it is true?
  • Is there a public interest element — is this about more than your own employment situation?
  • Who is the appropriate recipient — your employer internally, or an external prescribed body?

After making a disclosure, keep records of everything — the disclosure itself (in writing if possible), the date, how it was made, and the response. If you subsequently face adverse treatment, document every incident with dates, times, and witnesses.

If you are dismissed or subjected to detriment following a protected disclosure, contact Acas immediately and register for Early Conciliation. You must bring a claim within three months less one day of the act of dismissal or detriment.

Protection After Whistleblowing

If you make a qualifying disclosure and suffer a detriment or are dismissed as a result, you have legal protection. Whistleblowing dismissals are automatically unfair — there is no minimum service requirement and no cap on compensation. You can also apply for interim relief within 7 days of dismissal, which if granted means your employer must continue paying you until the tribunal hearing.

Keep records of your disclosure, who you told, when, and any changes in how you were treated afterwards. Detriments short of dismissal (such as being overlooked for promotion, excluded from meetings, or given unfavourable duties) are also actionable. You can bring a claim to the employment tribunal within 3 months (less 1 day) of the detriment or dismissal.

Frequently asked questions

Can I be dismissed for reporting a health and safety concern?
No. Raising health and safety concerns that you reasonably believe are genuine is a protected disclosure under PIDA. Dismissal for this reason is automatically unfair, regardless of your length of service. This is one of the strongest protections in employment law.
What if I report wrongdoing anonymously — am I still protected?
Protection under PIDA requires that your employer or the relevant body can identify you as the person who made the disclosure. Anonymous disclosures may not attract protection if it cannot be shown the disclosure was made by you. However, many organisations have anonymous reporting mechanisms and whistleblowing policies that provide additional organisational protections.
Can I blow the whistle directly to the media?
Only in limited circumstances — for example, if the wrongdoing is of an exceptionally serious nature, you reasonably believe you would face detriment if you disclosed internally or to a prescribed body, or evidence is likely to be concealed. The threshold for media disclosure is significantly higher than for internal or regulatory disclosures.
