DEFRA recognises the role water efficiency can play in reducing energy use, especially through reduced hot water consumption. Last September the Department launched a water efficiency campaign under the Act on CO2 banner which highlighted the energy and carbon implications of water use. DEFRA officials are in ongoing discussions with Department of Energy and Climate Change counterparts to coordinate the delivery of programmes to improve energy and water efficiency.
Each water company in England and Wales has had a duty to promote the efficient use of water by its customers. Ofwat is responsible for enforcing this duty and reports on progress in its annual Service and Delivery reports, available from its website. Following discussions within the Government-led Water Saving Group, Ofwat has introduced water efficiency targets for water companies from 2010-11 to 2014-15.
