An Energy Performance Certificate (EPC) is required whenever a domestic property is advertised for sale or let. After an assessment of the dwelling has been completed, the property will be placed in a domestic EPC band which ranges from A-G, with A being the best, and G being the worst rating.

The domestic EPC bands are linked to the estimated quantity of gas and electricity used at the property per year. The higher the estimated energy use, the lower the rating will be for the dwelling.

How ARE Domestic EPC bands calculated?

In order to calculate the domestic EPC band, the Domestic Energy Assessor (DEA) will visit the property and conduct an assessment. The assessor will need access to all areas of the property including any lofts and basements. The property will be measured, and data will be gathered relating to the construction of all external walls, floors and roofs. The assessor will need to document the date that each building part was originally constructed and then add details of any insulation that has been retro fitted since the original construction.

Data will also be collected for each of the following, heating and hot water system, windows and doors, light fittings, renewable energy systems, number and type of baths and showers, draught proofing and any other special features of the property. 

After the on-site assessment has been completed the DEA will enter the data in to approved software which is provided by their accreditation company. Once all the data has been entered, the calculation will be made by the software and the result confirmed. The EPC will then lodge to the Energy Performance of buildings register and can be found by searching by property address.
