UK water suppliers: who supplies your area
Mains water in England is supplied by regional companies. You cannot choose your supplier — it is set by your address — and the company that supplies your drinking water is not always the company that takes your wastewater away. The list below shows every supplier across the 583 towns WaterTrust covers, with contact details and the towns each one serves. Your own town page shows your supplier alongside local water hardness and typical prices for water and drainage work.
