2 Conclusion 42nd Report - Water sector regulation Accepted

Develop common survey standards and collate data to assess water infrastructure health for business plans

Over many years, the Environment Agency and Ofwat have failed to ensure water companies maintain vital infrastructure. Ofwat and the Environment Agency (EA) have not done enough to ensure companies actively manage their infrastructure. At the current rate of replacement, it would take companies 700 years to replace the entire …

Government response. The government agreed, committing to publishing a White Paper this autumn, Ofwat developing a new asset condition assessment methodology by 2027, and the Environment Agency increasing staff. Both regulators are also developing a Delivery and Monitoring Framework for water industry …

4 Conclusion 42nd Report - Water sector regulation Accepted

Ensure money raised from water company fines permanently goes to improving the system

The Environment Agency is failing to ensure that wastewater companies meet their environmental targets, resulting in excessive use of combined sewer overflows and environmental pollution. The EA and Ofwat are taking enforcement action against every wastewater company for their poor performance on storm overflows. Previous mismanagement has presented a risk …

Government response. The government states Ofwat has tripled enforcement capacity and uses regulatory tools to hold companies to account. The Environment Agency has exceeded inspection targets and transformed its regulatory approach. The Chief Executives of both regulators have written to the Committee …

5 Recommendation 42nd Report - Water sector regulation Accepted

Ofwat to review powers to improve water sector financial resilience and clarify insolvency costs

Financial fragility of a few large companies in the sector is leading investors to lose confidence in regulation as well as the sector. We need to return to a water sector that is low risk and low return. Currently, company group structures are complex, and some companies in groups are …

Government response. The government states Ofwat continuously monitors financial resilience and has secured £1.9 billion in new equity for six companies. A new single water regulator will be established, and the government will respond to the Independent Water Commission's recommendations in a …

6 Conclusion 42nd Report - Water sector regulation Accepted

Mandate Defra to clarify and fill gaps in water sector regulator responsibilities and trade-off considerations.

No-one is taking responsibility for ensuring that the regulatory system works, as is evident by its failings. Defra has overall responsibility for the regulatory framework. However, it is not planning an improvement of the system it describes as “piecemeal”. There are gaps in key areas such as oversight of the …

Government response. The government plans to abolish Ofwat and merge its functions into a single new regulator, subject to consultation this autumn. It will publish a Strategic Policy Statement and ministerial direction this autumn to clarify expectations and respond to the Independent …

7 Recommendation 42nd Report - Water sector regulation Accepted

Publish regulatory roadmaps for new water sector powers and future strategic changes by Autumn 2025.

Defra seems to be passively waiting for the Water Commission to report before making changes to the system. Defra has acknowledged the need for a complete reset of strategic planning and has committed to accepting the recommendations for the Water Commission, but it expects they may take legislation to fully …

Government response. The government will publish a White Paper for consultation and a new Water Reform Bill this autumn 2025, along with a transition plan. It will also clarify expectations through a Strategic Policy Statement and ministerial direction later in 2025, addressing …

On the basis of a report by the Comptroller and Auditor General, we took evidence from the Department for Environment, Food and Rural Affairs (Defra), the Environment Agency (the EA) and the Water Services Regulation Authority (Ofwat) on regulating the water sector.1 We also took evidence from the Chief Executive …

Government response. The government states there will be a quadrupling of investment in the water sector. Ofwat has established Price Control Deliverables to ensure companies deliver improvements and will track progress and publish a review next year. Ofwat will also engage with …

20 Conclusion 42nd Report - Water sector regulation Accepted

Most water company fines go to Treasury, delaying restoration fund disbursement

Over the period 2019 to 2024 water companies paid over £430 million in penalties as a result of enforcement action from the EA and Ofwat. Of the fines imposed by the EA, 84% went to HM Treasury.56 Defra told us that it is looking at ways of channelling money into …

Government response. The government recognizes the importance of using penalties paid by water companies to benefit the environment and cites the Water Restoration Fund as an example.

29 Conclusion 42nd Report - Water sector regulation Accepted

Urgent water sector issues persist despite new Act; key powers and accountability measures face delays.

Defra acknowledged that some issues were too pressing to wait until it implemented the Commission’s recommendations. Defra told us that it took some of the actions needed in the Water (Special Measures) Act. However, EA told us that its power to take action when storm overflows are used on days …

Government response. The government agrees that some issues are too pressing to wait, and cites the Water Act 2024 and Ofwat's consultation on the fit and proper person test as actions already taken.
