Loss Of Water Supply Or Pressure

Although the loss of supply or loss of water pressure is the responsibility of your Water Network Owner, Castle Water is responsible for administering payments, where they are due, under Ofwat’s Guaranteed Standards Scheme (GSS) for customers in England.

Castle Water will work with your Water Network Owner to administer GSS payments in certain situations if your supply has been interrupted or if your water pressure falls below the minimum pressure standard. This includes identifying customers who are entitled to GSS payments and ensuring we have accurate details of the supply losses suffered.

Customers in England seeking GSS payments can contact Castle Water directly to provide information and ensure that you receive the correct payment.

We are open 8am- 6pm, Monday to Friday. Call us on 01250 718700 or why not use our 5-star web chat service at
