Thames Water has returned to a full-year profit after hiking its customers bills by 40% last year.
The UK’s largest water company reported post-tax income of £113m for the 12 months to the end of March, swinging from a £1.51bn post-tax loss the previous year.
However, the firm’s net debt also swelled to £18.5bn from £16.8bn as it said it “continued to fund the business through… debt and internally generated cash flows”.
Chief executive Chris Weston said: “The progress we have made in turning the company around has meant we are now performing better.”
