Energy Performance Certificates (EPCs) - A summary of the new requirements (Version 2)

TRADA image

A building's energy needs for heating, cooling, lighting and electrical appliance usage account for about half of the energy consumed in the UK. Clearly, if energy consumption levels are to be reduced then energy use by buildings needs to play a very important role. This obvious conclusion led the EU to produce the Energy Performance of Buildings Directive (EPBD) in 2002, which defines the number of measures to be introduced into every member state by specified deadlines

One of the most important of these measures is the introduction of EPCs.

This Construction Briefing summarises the requirements related to Energy Performance Certificates (EPCs) in England & Wales. Similar but separate arrangements have been developed for Scotland and Northern Ireland, with separate implementation dates.

This sheet also gives readers some background information including an explanation as to why the introduction of EPCs was necessary and the proposed a timeframe for implementing the new requirements.
