Thames Water has asked creditors to approve an additional £2.4 billion in emergency funding, taking its proposed financial facility to £5.4 billion as Britain’s largest water company battles to secure its long-term future.

The company announced the request on 15 October 2026, saying the expanded facility would help it continue operating into autumn 2027 while a wider recapitalisation plan is developed. Thames Water warned that, under its latest forecasts, it could run short of funds by the end of 2026 or early 2027 without further support.

Heavy Debt Adds to Pressure

The utility has approximately £20 billion in debt and has already drawn £2.65 billion from its existing £3 billion emergency facility. Years of underinvestment in ageing infrastructure have added to the company’s financial and operational challenges.

Its major creditors are pursuing a potential rescue involving debt write-downs and new equity investment. Thames Water says the additional funding would also support its capital investment programme and planned improvements for customers and the environment.

Creditors Face an Important Decision

Creditors have until 29 October to vote on changes needed to expand the funding facility and allow further borrowing. The proposal requires amendments to existing financing conditions and is part of continuing negotiations over the company’s future.

The outcome could have significant implications for Thames Water, its customers and the wider UK water sector. However, the funding increase is not yet guaranteed, and the longer-term rescue remains subject to creditor approval and further arrangements.
