It is a pleasure to serve under your chairmanship, Ms Bardell. I thank the hon. Member for Oxford West and Abingdon (Layla Moran) for bringing this incredibly important debate on the performance of Thames Water before the House. Thames Water's performance is completely unacceptable, and it must take urgent steps to turn this around. According to Ofwat, Thames Water is failing to meet its commitments to customers on eight of the 12 common performance metrics, particularly on ensuring a consistent supply of water and on its pollution instances. The Government and regulators do not take underperformance lightly; as a result, Ofwat has directed Thames Water to return over £73 million to customers during the financial year of 2024-25, which is in addition to £51 million returned to customers during 2022-23. The Government will hold the water company to account through the use of the regulators—the Environment Agency and Ofwat. Thames Water must start turning its performance around by producing a service commitment plan that details how it will address the issues raised today. I have met with the new chief executive of Thames Water and will continue to monitor their progress closely. I also addressed specific points made about bathing water status, storm overflows, supply interruptions, sewer flooding, Abingdon reservoir, Witney sewage treatment works, and strengthened regulation by the Environment Agency. The Government are providing £2.2 million per year specifically for water company enforcement activity. All water companies, including Thames Water, must clean up their act, behave transparently, and take urgent action to improve their performance.
