A Display Energy Certificate (DEC) shows the energy performance of a building, based on the Operational Rating (OR), on a graphical scale from A (very efficient) to G (least efficient).

An Energy Performance Certificate is a legal requirement whenever a property is built, sold or rented.
Since October 2008, legislation has made it illegal to market a property without a valid EPC.

Air conditioning inspections are a legal requirement under the Energy Performance of Buildings Directive (EPBD). This legislation is designed to improve the energy efficiency of public and commercial buildings, and reduce carbon emissions.

Under the Energy Act 2011, from April 2018 onwards, there will be amendments made to the EPC requirements for property owners, under the name of the Minimum Energy Performance Standards (MEPS), also known as the Minimum Energy Efficiency Standards (MEES).

The Energy Saving Opportunity Scheme (ESOS) is UK legislation (based on article 8 of the EU Energy Directive) which mandates nearly 10,000 organisations in the UK to audit their estates to establish opportunities for savings in energy.

The Energy Companies Obligation (ECO) was introduced in 2013 to legally make large energy suppliers deliver energy to domestic energy users.
