Retail market for business customers

The Water Act 2014 enables the creation of a new market for retail water and sewerage services to eligible business customers (businesses, charities and public sector organisations) in England. This new market will work effectively with the existing market in Scotland.

We are working closely with the UK Government (Defra) and Market Operator Services Limited (MOSL) to deliver the programme of work (‘Open Water’) to open the new market. Visit to find out more.
