The Energy Services Directive will promote energy efficiency in the UK and must be fully implemented by 17 May 2008. It will impact on both providers and users of energy. The Directive’s full name is the EC Directive on Energy End Use Efficiency and Energy Services and, as announced in the Energy White Paper, new policy measures may be needed to implement it. Defra has lead responsibility for implementing the Directive and is working closely with other government departments and the devolved administrations to ensure it is implemented on time.
