In a move aimed at revitalising the water industry, the UK government has announced sweeping changes to the way water companies are regulated and held accountable. The proposed reforms, set to be unveiled in a new white paper, include provisions that could see firms avoid hefty fines for environmental breaches as part of a broader effort to stabilise the sector.
The environment secretary, Emma Reynolds, has hailed the changes as “once-in-a-generation reforms” that will introduce “tough oversight, real accountability and no more excuses.” However, campaigners have criticised the plans, arguing that they amount to letting companies “off the hook” for their failings.
Under the new system, a “turnaround regime” would be established to force struggling water firms, whether financially or in terms of sewage pollution and water outages, to address their problems more swiftly. This could involve the regulator deferring or even waiving penalties, in order to provide “stability to investors” and prevent companies from collapsing.
The move comes as Thames Water, one of the UK’s largest water suppliers, has asked its creditors to forgive fines the company has incurred, as it battles to stave off financial collapse. In May 2025, Thames Water was fined over £120 million for environmental breaches involving sewage spills, after failing to operate and manage its treatment works and wastewater network effectively.
Richard Benwell, CEO of Wildlife and Countryside Link, criticised the proposed changes, stating: “If a company is fined because it’s done something wrong, it should either make restitution or the polluter should pay.” He added: “It sounds like a desperate play to be off the hook at the last minute, and companies should think about that when they are engaging in unlawful actions and failing in their public environmental interest duties.”
Alongside the potential for fine forgiveness, the government’s water sector overhaul will also introduce a new “MOT for water companies,” forcing firms to disclose the state of their infrastructure. This measure is aimed at preventing water outages, such as those recently experienced by tens of thousands of people in Kent and Sussex, where old pipes and poorly maintained treatment centres were blamed for the shortages.
Other changes include the creation of dedicated supervisory teams for each water company, “no notice” inspection powers for the new regulator, and the appointment of a new chief engineer within Ofwat to oversee hands-on checks of water infrastructure.
The overhaul is part of the government’s response to a wide-ranging report on the water sector by Jon Cunliffe, a former Bank of England official, who made 88 recommendations to improve the industry. While the ownership structure of water companies will remain unchanged, the reforms aim to address long-standing issues plaguing the privatised system.
