Is a whistleblowing policy a legal requirement in the UK?
Not for most employers. GOV.UK's guidance for employers says you are not legally required to have one. Sector rules apply to some: UK banks and Solvency II insurers (FCA and PRA rules), and organisations providing NHS care, which must adopt the national Freedom to Speak Up policy. The law protects workers who blow the whistle whether or not you have a policy.
What should a whistleblowing policy include?
GOV.UK lists what a typical policy includes: what whistleblowing is, how to raise a concern, training, fair and consistent treatment, confidentiality, anonymous reporting and its limits, the feedback people can expect, timeframes, a clear statement that victimisation is unacceptable, that no evidence is needed, where to get advice, and how to raise concerns with prescribed persons.
What changed in whistleblowing law in 2026?
Since 6 April 2026, a disclosure about sexual harassment can be a protected disclosure. Since 1 October 2026, workers have 6 months to bring a whistleblowing detriment or dismissal claim where the act or dismissal happened on or after that date. GOV.UK published new guidance for employers, the National Guardian's Office closed on 30 June, and the list of prescribed persons changed. Rules on confidentiality agreements are expected in 2027.
Can you be dismissed for whistleblowing?
Dismissing an employee because they made a protected disclosure is automatically unfair. There's no minimum length of service and no cap on compensation. Workers who aren't employees are protected from being treated badly, including having their contract ended, because of a disclosure. Colleagues who victimise a whistleblower can be personally liable.
What doesn't count as whistleblowing?
A complaint about your own treatment, such as your pay or a dispute with a colleague, usually counts as a grievance, unless it's also in the public interest. A disclosure isn't protected if making it is a criminal offence, or if it reveals legal advice the person received in confidence.
Is sexual harassment covered by whistleblowing law?
Yes. Since 6 April 2026, telling your employer or a prescribed person that sexual harassment has happened, is happening or is likely to happen can be a protected disclosure. The person still needs to reasonably believe it's in the public interest. Acas says the protection applies to detriment or dismissal from 6 April 2026, even if the disclosure was made earlier.
How long does someone have to bring a whistleblowing claim?
Where the act or dismissal happened on or after 1 October 2026, a worker has 6 months to bring a tribunal claim. For earlier acts, the limit is 3 months. They must contact Acas for early conciliation first.
Can whistleblowers stay anonymous?
Yes. Your policy should explain how to report anonymously, and that anonymous concerns are harder to investigate and may limit the feedback you can give. Keeping someone's identity confidential is different: they give their name, and you take reasonable steps to protect it.
Who are prescribed persons?
Regulators and other bodies named in law that workers can report concerns to, for example the Health and Safety Executive, the Equality and Human Rights Commission, HMRC, the Care Quality Commission and the Financial Conduct Authority. GOV.UK publishes the full list. A worker can also contact their MP.
Does UK whistleblowing law apply in Northern Ireland or the EU?
No. Northern Ireland has its own law, which doesn't include the sexual harassment category. In the EU, the Whistleblowing Directive requires employers with 50 or more workers in a member state to set up internal reporting channels, acknowledge reports within 7 days and give feedback within 3 months, under each country's own law.
