United Kingdom water and sewerage companies
Water only suppliers not shown

Water supply and sanitation in the United Kingdom is provided by a number of water and sewerage companies. Twelve companies and organisations provide drainage and sewerage services, each over a wide area, to the whole United Kingdom; and supply water to most customers in their areas of operation. There are also 'water only' companies which supply water in certain areas. Some companies are licensed to supply water or sewerage services using the networks of other providers.
