The company said its board “made this unanimous decision after concluding that the Final Determination for the regulatory period 2025 to 2030 does not appropriately support the investment and improvement that is required for Thames Water to deliver for its customers, communities and the environment for the next five years.”.
Chairman Sir Adrian Montague said: “We have taken the decision to refer our Final Determination to the Competition and Markets Authority in the interests of our customers and the environment.
Thames Water has escalated its row with regulator Ofwat over the bills it can charge customers over the next five years by launching an appeal to the competition watchdog.
“After careful consideration, our analysis shows that our Final Determination for the next regulatory period will continue to impact our ability to fund the improvements our customers and the environment so rightly want and deserve.”.
Britain’s biggest water supplier said it has asked Ofwat to refer its decision on bill increases to the Competition and Markets Authority (CMA).
