Water bills across the country are expected to be reduced by £240 million by 2030 as penalties are levied against underperforming suppliers, industry regulator Ofwat has announced.

Under draft proposals from the watchdog, several companies will face financial penalties for failing to meet environmental and customer service targets during the 2025-26 financial year, with the money handed back to domestic and business customers through reduced charges.

The provisional framework outlines a total net bill reduction of £240 million up to 2029-30, including £107 million to be returned to billpayers in 2027-28.

However, these savings are likely to be swallowed up for many households by separate Ofwat plans permitting suppliers to raise annual bills by an additional £3.4 billion — on top of an average 36 per cent price increase already approved over the five years to 2030.

Under the draft measures, Yorkshire Water and Thames Water face the largest underperformance deductions from bills in April 2027, at £75 million and £46 million respectively. Conversely, some suppliers will receive outperformance payments, with the largest granted to Severn Trent and Northumbrian Water.

Ofwat stressed that changes to bills are “affected by a range of factors and the effect will vary by company and customer type”.

It will make its final decision on so-called outcome delivery incentive payments by 15 December, which will take effect on bills from April 1 next year.

The regulator sets performance commitments for each company, with service levels that companies are expected to achieve over the five years to 2030.

Each commitment on performance has an outcome delivery incentive that has financial impacts for companies if they outperform or underperform against those targets.

Prime minister Andy Burnham unveiled plans late last month for new laws to pave the way for public ownership of failing water firms, and vowed a 10-year path to a “very different water system” in the UK.

In his speech at the Labour Party conference, Mr Burnham said environment secretary Dame Angela Eagle would present a “strengthened Water Bill to Parliament”.

It raised the spectre of a possible temporary nationalisation of debt-laden Thames Water as the government looks to decide on a £10 billion rescue takeover put forward by lenders for the UK’s biggest water supplier.

The announcement came after Mr Burnham said customers “cannot be treated as a blank cheque” after Ofwat announced plans in August to allow yet more bill increases on top of those already agreed.

The water industry continues to come under fire over sewage spills, supply failures and executive pay with calls growing for many firms to be brought back into public ownership.

A government spokesman said: “This government won’t allow customers to be treated as a blank cheque, and we are committed to protecting households from cost-of-living pressures.

“We will always challenge water companies where they seek to pass unnecessary costs onto households.

“We will deliver a strengthened Water Bill that puts people first, ensuring affordable access to clean water, driving down pollution, and strengthening public control.”
