The UK government is preparing to tighten its response to persistent pollution by water companies, including stronger restrictions on executive bonuses and increased scrutiny of firms
responsible for serious environmental damage.
Environment Secretary Dame Angela Eagle announced the plans on 29 October 2026, following the publication of the first joint performance report by the country’s four main water industry regulators. The report brings together information from the Environment Agency, Natural Resources Wales, the Drinking Water Inspectorate and Ofwat, providing a more comprehensive assessment of companies’ environmental, financial and operational performance.
The government says the coordinated approach will make it harder for underperforming companies to avoid accountability by pointing to positive results in one area while failing to meet standards in another.
The announcement comes alongside the Environment Agency’s latest Environmental Performance Assessment, which highlights the continuing problem of pollution incidents across the water industry. Only one company achieved the highest four-star performance rating, while six Category 1 pollution incidents were recorded in 2025. These incidents are classified as having a major, serious, persistent or extensive impact on the environment, people or property.
The sites associated with the six most serious incidents will be prioritised for visits by the Environment Secretary, who intends to examine companies’ responses and demand explanations for their failures.
Ministers will also establish specific improvement requirements for individual water companies. These will focus on reducing pollution, tackling water leakage from ageing infrastructure and improving customer satisfaction.
Executive bonuses face further restrictions
The government is also considering tougher measures to prevent water company executives from receiving bonuses despite continued poor performance.
Under rules introduced in 2025, companies awarded a one-star environmental performance rating are automatically subject to restrictions on executive bonuses. The same provisions apply to firms responsible for Category 1 pollution incidents.
The existing framework means bonus payments will be blocked for executives at Southern Water, Thames Water, South West Water and Yorkshire Water because of their one-star ratings. The government also says six chief executives will face automatic bonus bans under the rules linked to serious pollution incidents.
However, ministers believe the current arrangements may not go far enough to address repeated failures. Further details on strengthening the restrictions are expected to be announced in the coming weeks.
Dame Angela Eagle said water companies had repeatedly failed the public, arguing that the latest findings demonstrate the need for fundamental reform of the sector.
She said consumers expected cleaner rivers, lakes and seas, alongside assurances that money collected through their bills would be invested effectively rather than wasted.
The Environment Secretary added that the government would demand answers from companies with poor records and increase scrutiny of the most serious offences.
Regulators to coordinate enforcement
The publication of the joint report represents a step towards a more integrated regulatory system for England and Wales, ahead of plans to establish a single new water regulator.
By combining their data, the four watchdogs aim to provide a clearer picture of how companies perform across environmental protection, drinking water standards and financial regulation. The government believes this will improve transparency and make it more difficult for companies to deflect criticism by highlighting strong results in isolated areas.
Ministers will meet the chief executives of underperforming companies to seek explanations for their results and updates on the delivery of essential infrastructure projects.
The government has also warned that regulatory authorities are prepared to use the full range of enforcement measures against companies that fail to meet their obligations. These include financial penalties and criminal prosecutions where applicable.
The latest measures build on the Water (Special Measures) Act 2025, which expanded regulators’ powers and introduced rapid, automatic penalties. Ministers are now seeking to strengthen those arrangements further through the proposed Water Bill, with the aim of ensuring that persistent failures lead to more significant consequences.
The government has also set out expectations for the next water industry Price Review, stressing that companies must provide better value for money for households facing financial pressure.
The latest announcement signals an intensification of efforts to hold water companies and their senior executives accountable for pollution and inadequate performance, with the government promising closer monitoring, clearer improvement targets and tougher enforcement.
