Thames Water has returned to a full-year profit after raising its customers’ bills by about 40% last year, according to its latest results. The UK’s largest water company reported post-tax income of £113m for the 12 months to the end of March, reversing a post-tax loss of £1. 51bn recorded the prior year.

Net debt rose to £18. 5bn from £16. 8bn as the company said it continued to fund the business through debt and internally generated cash flows.

Chief executive Chris Weston said the company’s progress in turning the business around has translated into improved performance. The results follow a June government rejection of a proposed rescue deal for Thames Water. Under the terms discussed, lenders sought relief from future pollution fines in exchange for wiping off about £9.

4bn of debt and providing new funding. Thames Water added that it has enough debt funding to operate through to Q4 2026.
