The Directive requires new and refurbished buildings to meet minimum energy standards, and that existing buildings be rated for energy performance. The challenge has long been expected as the UK has struggled to transpose the Directive (ENDS Report 370, pp 28-31 ).
The Commission says the UK "has failed to provide information to demonstrate convincingly that [it] has fully implemented the necessary measures." It flags up issues over energy performance certificates, boiler inspections and air conditioning units in Northern Ireland and use of the Directive in Gibraltar.
France, Latvia, Greece and Belgium are also facing court action over the same law.
