To ask the Secretary of State for Communities and Local Government whether energy performance certificates may make reference to the performance of (a) light bulbs, (b) fridge-freezers and (c) dishwashers in a property. (226682)

The ratings on the EPC provide a measure of the overall energy efficiency of a domestic property and its environmental impact, calculated in accordance with a national methodology that takes into account factors, such as insulation, heating and hot water systems, ventilation and fuels used.

Light bulbs are mentioned in the EPC, where there is a recommendation to install low energy lighting, because lighting is an integral part of the property’s structure. Fridge-freezers and dishwashers, which are subject to their own rating system, are not part of the overall calculation of CO₂ emissions and energy use calculations and are, therefore, not referred to in the EPC.
