The market in England is open!

Switch today.

From April 2017, all businesses in England, regardless of size, will be able to choose their water and wastewater retailer. This is similar to the way you can currently choose your energy or telecoms retailer. This is already in place in Scotland where there has been an open market since 2008. This market change only applies to businesses and not household customers.
