First, I thank my right hon. Friend the Member for Romsey and Southampton North (Caroline Nokes) for bringing the matter of ensuring that water companies are performing adequately before this House. I think we all agree that this is an incredibly important and serious issue. I have been clear that water companies’ current performance is totally unacceptable and that they must act urgently to improve to meet Government and customer expectations. The British people expect better and so do this Government.
We have committed to deliver clean and plentiful water, as set out in the environmental improvement plan, and we have set out clearly how water companies must deliver that. First, our strategic policy statement to Ofwat, the water company regulator, sets out four clear priorities for water companies to protect and enhance the environment, deliver a resilient water sector, serve and protect consumers, and use markets to deliver for our customers.
Secondly, we have set new duties, through the Environment Act 2021, on water companies to monitor their overflows and set new legally binding targets to restore our precious water bodies to their natural state by cracking down on harmful pollution from sewers and abandoned mines, and improving water usage and households.
Thirdly, the storm overflow reduction plan, launched back in the summer, requires the largest investment programme in water company history and builds on the existing statutory duties. Water companies already have a statutory duty to provide a supply of wholesome water under the Water Industry Act 1991 and associated water quality regulations. They must ensure the continuation of their water distribution functions during an emergency.
I will begin by addressing my right hon. Friend’s concerns, because she has been in touch. I appreciate the lengths to which she has gone to hold her own water company to account, particularly over the supply interruptions experienced by Southern Water’s customers following multiple emergency incidents back in December 2022. A more recent incident last week led to approximately 15,000 Southern Water customers being off supply for an extended period, as she will know. Although some supply interruptions cannot be avoided, the repeated failure to properly ensure customers’ continued water supply is totally unacceptable. I will be meeting with Southern Water’s chief executive officer to understand how it plans to address its failings.
