The Government believe they have done all that is required to implement the Internal Market in Electricity and Gas directives. The Commission was notified of the implementation of the directive (except for provisions relating to the requirement for electricity companies to disclose their fuel mix to final customers and the requirement for Ofgem to act as dispute settlement authority between energy undertakings) in October 2004. No assessment has been made of the effects on energy prices of the timing of the implementation of each directive.
