Public Interest Disclosure Act rights and detriment claims in the UK

UK Whistleblowing Protection 2026

If you’re a whistleblower in the UK, understanding your rights under the Public Interest Disclosure Act 1998 is crucial to protect yourself from detriment claims. The Act provides a framework for employees to disclose information in the public interest, and we’ll guide you through the process and your rights in 2026.

Introduction to Whistleblowing Protection in the UK

The Public Interest Disclosure Act 1998 (PIDA) is a UK law that protects employees who blow the whistle on wrongdoing, such as fraud, corruption, or health and safety risks. According to Section 43A of the Employment Rights Act 1996, as amended by PIDA, employees are protected from detriment or dismissal for making a protected disclosure. This means that if you report a concern in good faith, your employer cannot treat you unfairly or sack you. For instance, in the case of Cavendish Munro v Geduld (2010), the Employment Appeal Tribunal (EAT) held that an employee’s disclosure about a colleague’s misconduct was a protected disclosure. In the UK, the whistleblowing framework is also supported by the Employment Rights (Miscellaneous Amendments) Regulations 2019, which removed the requirement for a worker to have a reasonable belief that their disclosure is in the public interest.

Key takeaway: Understand that the Public Interest Disclosure Act 1998 protects you from detriment claims if you make a protected disclosure in good faith.

What Constitutes a Protected Disclosure?

A protected disclosure is a disclosure of information that the worker reasonably believes is in the public interest and tends to show one or more of the following: a criminal offence, a breach of a legal obligation, a miscarriage of justice, a danger to the health or safety of any individual, damage to the environment, or the deliberate concealment of any of these. As outlined in Section 43B of the Employment Rights Act 1996, the disclosure must be made to the employer or a prescribed person, such as a regulator. For example, the Financial Conduct Authority (FCA) is a prescribed person for disclosures related to financial services. The case of Kilraine v London Borough of Wandsworth (2018) illustrates that a disclosure can be protected even if it is not exclusively about a public interest matter, as long as the worker has a reasonable belief that it is in the public interest.

Key takeaway: To make a protected disclosure, ensure you have a reasonable belief that the information is in the public interest and tends to show one of the specified wrongdoings.

Procedure for Making a Protected Disclosure

It is essential to follow the correct procedure when making a protected disclosure. According to the UK Government’s guidance, workers should first raise their concerns with their employer, either through their line manager, HR department, or a dedicated whistleblowing channel. If the worker does not receive a satisfactory response or believes the issue is too serious to be reported internally, they can disclose the information to a prescribed person. In some cases, workers may also be able to make a disclosure to a legal adviser. The Employment Rights (Miscellaneous Amendments) Regulations 2019 emphasize the importance of having effective whistleblowing policies in place. For instance, the policy should outline the procedures for making a disclosure, how the disclosure will be handled, and the protection available to workers who make a protected disclosure.

Key takeaway: Follow your employer’s whistleblowing policy or the UK Government’s guidance to ensure you make a protected disclosure correctly.

Detriment Claims and Compensation

If you have been subjected to detriment, such as being passed over for promotion, given a poor performance review, or bullied, because you made a protected disclosure, you can bring a detriment claim. According to Section 47B of the Employment Rights Act 1996, a worker can claim compensation if they have suffered detriment. The amount of compensation is determined by the Employment Tribunal and can include injury to feelings, loss of earnings, and other expenses. For example, in the case of Royal Mail Group Ltd v Jhuti (2019), the Supreme Court held that an employee’s disclosure about a colleague’s misconduct was a protected disclosure, and the employee was entitled to compensation for detriment. In the UK, the maximum compensatory award for unfair dismissal is currently £89,493, as outlined in the Employment Rights (Increase of Limits) Order 2022.

Key takeaway: If you have been subjected to detriment for making a protected disclosure, you can claim compensation through an Employment Tribunal.

Comparison with Other Jurisdictions

Whistleblowing protection laws vary across jurisdictions. For instance, in India, the Whistle Blowers Protection Act 2014 provides protection to whistleblowers who disclose information about corruption, misuse of power, or criminal offences. In the UAE, Federal Law No. 20 of 2018 on Anti-Corruption provides protection to whistleblowers who report corruption. However, the level of protection and the procedures for making a disclosure differ significantly. In the EU, the Whistleblower Protection Directive (2019/1937) sets out minimum standards for whistleblower protection, including confidentiality, protection from retaliation, and effective reporting channels. Understanding these differences is essential for multinational companies and individuals working across borders.

Key takeaway: Be aware of the differences in whistleblowing protection laws across jurisdictions, including the UK, India, UAE, and EU, to ensure you understand your rights and obligations.
