An Energy Performance Certificate Survey (or EPC Survey), completed by an accredited Energy Performance assessor, gives you a graded score for the energy efficiency of your building and gives you details on how to improve it.

In order to perform an EPC Survey, the DEA (Domestic Energy Assessor) will need to inspect the property for the construction of the walls and roof; signs of wall-cavity insulation; energy-saving devises; the number and installation date of double glazed windows; the number of open and closed fireplaces; make and model of boiler; the number of low energy light-bulbs; type of heating system used; thickness of roof insulation; thickness of foam on hot water cylinder; measurements of conservatories and extensions; number of heated rooms; year of construction and layout of the home. A full EPC Survey can take anywhere between 20 minutes and 1 hour.

To organise an EPC Survey you will need to commission a local Energy Performance assessor through the Energy Performance Certificate Register website or through your local phone book. Once the EPC Survey is completed, the EPC will last for 10 years or until a new EPC Survey is commissioned.

By law you should commission an EPC Survey when you are considering selling or letting a property that you own. Legally you should also receive a copy of an EPC Survey report when you are considering buying or renting a new home. Failure to provide these details prior to the finalisation of a contract can result in fines from Trading Standards.

Alternatively, you can also commission an EPC Survey to review the energy efficiency of your home and implement suggested changes that can reduce your household expenditure. Knowing your own EPC rating also allows you to look at the EPC of other properties on the EPC register website and to compare the efficiency of your home with similar homes.
