Building Regulations covering energy efficiency

The technical requirements for energy efficiency in each of the UK nations’ Building Regulations may differ. However the overall aim is the same: to cut home energy use and CO2 emissions.

In some areas, there may also be policies which require improvements that cut energy and emissions beyond the statutory minimum standard. Examples of these are the Code for Sustainable Homes, Ecohomes and local ‘Merton Rule’-type policies.

Also, every time a dwelling is either purchased or rented by a new occupant, it is a legal requirement to provide that occupant with an energy performance certificate (EPC). This shows the energy efficiency of the dwelling’s heating/hot water system, fixed ventilation and lighting installations. It has been shown that high levels of energy efficiency are attractive to buyers and tenants.

England and Wales

The main way to demonstrate compliance with Building Regulations in England and Wales is to follow the guidance set out in the Approved Documents (ADs). These are issued by the Department of Communities and Local Government (CLG) and accompany the Building Regulations (as amended) 2000. Part L of the regulations covers energy efficiency. This guidance is split into four categories:
