About the market

From April 2017, 1.2 million eligible business customers (businesses, charities or public sector) mainly in England will be able to choose who supplies their water and wastewater (also known as ‘sewerage’) retail services. Retail services include things like water meter reading and customer services.

Once open, the new market will be the largest retail water market in the world, delivering an estimated £200 million of overall benefits to customers and the UK economy. Being able to switch water and wastewater retailer will mean that business customers are able to negotiate the best package that suits their needs. Or by successfully applying for a licence, business customers can also choose to supply themselves with retail services.
