Whistleblowing reform: what has actually changed since the promises

The Bill that never got debated

The Office of the Whistleblower Bill was introduced in the Commons by Gareth Snell in December 2024, and it was ambitious. Its long title promised an independent Office able to set, monitor and enforce standards for the management of whistleblowing cases, to provide disclosure and advice services, to direct investigations and – the sharpest departure from current law – to order redress for detriment suffered by whistleblowers. That last power would have given whistleblowers somewhere to go before an Employment Tribunal, or instead of one.

It went no further. The Bill was a private member’s bill introduced under the ten-minute rule; it received its formal first reading on 18 December 2024, and its second reading was never taken. When the 2024-26 session of Parliament ended, the Bill fell with it, and as of 8 September 2026 no whistleblowing bill – government or private member’s – has been introduced in the session that began in May 2026. The pattern is now familiar enough to be part of the story. Parliament’s own bills records show six private members’ bills on whistleblowing or an Office of the Whistleblower since 2020, in both Houses; none of them progressed beyond second reading, and most were never debated at all.

None of this means the proposals were eccentric. The same core design – a single body with oversight, investigation and redress powers – kept returning session after session under sponsors from different parties. What the record shows is not that the idea was rejected on its merits, but that it was never tested on them, because private members’ bills without government time almost never are.

A review that gathered evidence, not a plan

The government’s own contribution to the reform debate arrived in July 2025. The Department for Business and Trade published an independent research report by Grant Thornton on the effectiveness of the whistleblowing framework in Great Britain, a review commissioned by the previous government in 2023. The report is explicit about what it is not: it contains no overarching conclusion on whether the framework works, and no formal recommendations – it records observations, emerging themes and suggestions for change drawn from the literature and from participants.

That distinction matters. A review with recommendations creates something a government can be held to; a review that gathers observations creates a file. The report’s contents are nonetheless useful evidence. Among its recorded themes, whistleblower participants expressed surprise that prescribed persons – the regulators and bodies to whom protected disclosures can be made – largely have no remit to respond to allegations of detriment and cannot generally protect the person who reports to them. The receiving body can act on the wrongdoing; what happens to the worker afterwards is, in general, not its problem. No government bill implementing any reform programme has followed the report.

What has actually changed

It would be wrong to say nothing moved. Three changes are real, in force or imminent, and verifiable on the face of official sources.

First, the Employment Rights Act 2025, which received Royal Assent on 18 December 2025, amended the Employment Rights Act 1996 so that a disclosure tending to show that sexual harassment has occurred, is occurring or is likely to occur is an express qualifying disclosure. That change came into force on 6 April 2026. Before it, there was no sexual harassment category in terms: a worker reporting sexual harassment had to argue that the disclosure fitted one of the existing heads, such as breach of a legal obligation. The category is now there in terms.

Secondly, the prescribed-persons regime has been expanded twice by secondary legislation. The most recent order, in force from 2 June 2026, added the Building Safety Regulator, the Independent Football Regulator, the Security Industry Authority, the Creative Industries Independent Standards Authority, the Secretary of State for Science, Innovation and Technology, and the Law Society – including the Solicitors Regulation Authority – to the list of prescribed persons, and updated several existing remits. An earlier 2025 order added HM Treasury and extended the Business and Trade and Transport entries to sanctions matters. This is incremental maintenance rather than reform, but it is not nothing: each addition is a new external route through which a disclosure can qualify for protection.

Thirdly, from 1 October 2026 the time limit for most Employment Tribunal claims increases from three months to six months. That is a general employment-law change, not a whistleblowing measure, but whistleblowing detriment and dismissal claims are among those it will affect – and for workers who only understand their position months after the event, it is a practical widening of the door.

What protection a whistleblower has today

The framework that protects a worker blowing the whistle in Great Britain today remains Part IVA of the Employment Rights Act 1996, inserted by the Public Interest Disclosure Act 1998. A disclosure qualifies for protection only if the worker reasonably believes it is made in the public interest and reasonably believes it tends to show one of the listed categories of wrongdoing – criminal offences, breach of a legal obligation, miscarriage of justice, danger to health and safety, damage to the environment, sexual harassment, or the deliberate concealment of any of these. A grievance about the worker’s own treatment, without more, still struggles to fit.

The route the disclosure takes matters as much as its content. Disclosure to the employer is protected in the simplest case; disclosure to a prescribed person carries extra conditions, including a reasonable belief that the information is substantially true; and wider disclosure – to the press, for example – is protected only where further conditions are met, such as a reasonable belief that the worker would suffer detriment for raising it internally, or – where no prescribed person covers the matter – that evidence would be concealed or destroyed, or that substantially the same disclosure has already been made, with reasonableness judged against statutory factors. The tiered structure rewards the worker who goes internal first, then to the regulator, and treats public disclosure as the last resort.

If the disclosure is protected, the worker has the right not to be subjected to any detriment by the employer on the ground of that disclosure, and that right extends also to detriment by co-workers and agents, for which the employer can be liable. If the worker is an employee and is dismissed, dismissal where the reason or principal reason is the protected disclosure is automatically unfair – and the usual two-year qualifying period for unfair dismissal does not apply. It is a day-one right. There is also an emergency lever that many workers never hear about in time: an employee dismissed for a protected disclosure can apply to the Employment Tribunal for interim relief, which can keep the contract alive pending the hearing – but the application must be presented within seven days of the dismissal taking effect. Seven days. Miss it and the remedy is gone, whatever the merits.

One protection is absolute and worth stating plainly: any contractual term that purports to stop a worker making a protected disclosure is void. A confidentiality clause or settlement agreement cannot lawfully gag a protected disclosure. That position will be reinforced from 2027, when further Employment Rights Act 2025 provisions are due to void clauses that would prevent workers from alleging or disclosing work-related harassment or discrimination.

The distance between proposal and position

Measured against what reformers asked for, the honest verdict is that the framework has been serviced, not rebuilt. Everything in the current law works after the event: the disclosure is made, the detriment happens, and the worker’s protection is a claim. Nothing in it obliges anyone to investigate the concern, to keep the whistleblower safe while it is looked at, or to answer for a badly handled case – the functions the proposed Office was designed to carry.

The practical position for a worker today therefore comes down to disciplines the statute quietly rewards. Put the disclosure in writing and keep a copy. Choose the route deliberately, because the tiered rules mean the same words can be protected in one channel and unprotected in another. Diarise the short deadlines – seven days for interim relief, and the tribunal time limit, three months until 1 October 2026 and six months after – before doing anything else. And read any settlement wording against the statutory rule that a protected disclosure cannot be contracted away.

Reform may return; it has been proposed too often, by too many sponsors, to stay off the agenda permanently. But workers cannot litigate on the strength of bills that fell. The law that will actually decide their case in 2026 is the 1998 framework, with its new edges – and it rewards preparation far more reliably than it rewards hope.
