Your Supply

From April 2017, the majority of businesses will be able to choose which company provides their retail services for their water, sewerage and trade effluent. This is part of a Government initiative called Open Water. Click here to find out more.

If you have not been contacted by a retailer, you will remain a customer of Cambridge Water. Please continue to use our website in the usual way.

We cover an area of 453 square miles which includes Cambridge city and extends to Ramsey and St Ives in the north, Balsham in the East, Gamlingay in the West and Melbourn in the South.
