Since April 2017, businesses and organisations in England have been able to choose which company supplies their business premises with water and wastewater services (similar to the energy and telecom sector).
This means they can switch their water and sewerage retailer, choosing to use one retailer for both their water and wastewater supplies, or one retailer for each. We still supply their water and sewerage services and charge their retailer for this, who in turn sells this service to the business, as their customer.
