Water companies across England and Wales have been granted provisional approval to increase customer bills by an additional £3.4bn over the coming years. The regulator, Ofwat, stated that this funding is essential to address mounting pressures on water infrastructure and the environment. Nearly one-third of the approved amount is specifically earmarked for the maintenance of existing water services. The remaining funds are intended to meet rising demand from new housebuilding projects and data centers, as well as to address the presence of "forever chemicals" in the water supply.
The process of setting spending budgets for water firms occurs every five years, though this specific decision allows companies to apply for additional funds for projects that were not identified during the previous review. Ofwat reported that while water companies submitted requests totaling £4.3bn, some of these proposals were rejected. The current decision remains provisional, with a public consultation period underway and a final ruling expected in December. Helen Campbell, executive director for delivery at Ofwat, stated that the regulator will track company performance to ensure they deliver the expected improvements for customers and the environment, noting that expenditure can be clawed back if firms fail to meet their targets.
The financial impact on consumers will vary significantly between firms. Customers of five specific companies—Severn Trent Water, Southern Water, Thames Water, Wessex Water, and South East Water—are facing additional bill increases over the next two years, which will be added to hikes already announced in 2024. For example, Southern Water is set to charge customers an extra £43 next year, whereas South East Water will implement a £1 increase in 2029. The remaining eight water firms—Anglian Water, Dwr Cymru Welsh Water, Hafren Dyfrdwy, Northumbrian Water, South West Water, United Utilities, Yorkshire Water, and SES Water—would recover their additional spending through customer bills after 2030.
Ofwat has approved funding for several specific schemes, including infrastructure for new data centers in Manchester, additional wastewater capacity in Newquay, and accelerated work by Wessex Water to tackle PFAS pollutants, which was originally scheduled for 2030-35. Water companies argue that these investments are critical to replacing aging pipes, building new treatment plants, and establishing reservoirs. They contend that climate change has exacerbated these needs by increasing the frequency of heavy rainfall and heatwaves, which place further strain on infrastructure.
The decision has faced significant backlash from political figures and environmental advocates. Prime Minister Andy Burnham criticized the proposal, describing it as "real money out of family budgets at a time when they are struggling with the cost of living." He noted that he understands why consumers are angry, given that they have been asked to pay more for years while facing persistent leaks and pollution incidents. He warned that where water companies seek to pass unnecessary costs onto households, they will be challenged.
Environmental groups have been equally critical. Amy Fairman of River Action labeled the decision an "insult," arguing that water companies have failed to invest sufficiently over the last 30 years, leaving customers to deal with pollution and crumbling infrastructure. She called for greater public control of the industry, stating there should be "no more blank cheques for failure." Kierra Box, a water campaigner at Friends of the Earth, described the situation as "daylight robbery," noting that rivers and seas remain filled with sewage and chemicals despite previous bill hikes. Many consumers have expressed frustration at being asked to pay more while experiencing supply interruptions that sometimes last for days, alongside the inability to safely use local rivers, lakes, and beaches.
