What is an Energy Performance Certificate (EPC)?

An Energy Performance Certificate (EPC) is a documented record of the actual (current) and potential (future possible) energy saving aspects of a particular property. CO2 emissions are also highlighted.

Buildings are assessed using the Standard Assessment Procedure. Building performance is rated in terms of energy use per sq metre of floor area, energy efficiency based on fuel costs and environmental impact based on carbon dioxide (CO2) emissions.

The energy performance certificate details an Energy Efficiency Rating: A-G (100-1) and Environmental (CO2) Impact Rating: A-G (100-1)., where a rating of 100 is best and a rating of 1 is worst.

A summary of the buildings energy performance is provided relating to features such as: Walls, floors, roof, windows, heating, secondary heating, heating controls, hot water and lighting.

CO2 use will be also be highlighted.

As a result, recommendations will be made within the EPC to improve the particular building's Performance Ratings (A-G).

The EPC is then used as evidence of energy performance when the building is put up for sale or where renting tennants require the EPC.
