What is changing and how will this affect me?
From April 2017, eligible non-household customers (e.g. businesses, charities or public sector) mainly in England became 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. South West Water (Wholesaler) will invoice the Retailer with the wholesale water and sewerage charges. Customers will receive their water and sewerage service bills from the Retailer.
The eligibility criteria have been defined by the UK Water Regulator; Ofwat. Household premises are those in which, or in any part of which, the principle use of the premises is as a home. Non-household premises are those which do not fall into this category.
