EPC

Your EPC assessment should take about 30 - 45 minutes during which your assessor will measure your property and produce a floorplan noting features like windows, doors, heating and lighting types, wall thickness and loft insulation and he will take photo's of these features to confirm and back up his measurements as his work is regularly audited to ensure accuracy and consistency.

He may record the information that he collects by 'hand' or directly into a hand-held device such as an I-pad or mobile phone, either way the EPC assessment is a very standardised procedure requiring specific data to be inputted into the EPC software which means that an EPC produced for a property in one part of the country can be compared directly to an EPC produced for a property anywhere else in the country.

EPC Certificate

Once completed your EPC Certificate will show an Energy Rating for the property from A100 to G1 with A-ratings being the most energy efficient and G-ratings being least energy efficient.



In order to sell or rent a property in the UK you must achieve at least an E-rating.

The average energy rating for an typical domestic property in the UK is D60 however as new more efficient properties are built and improvements are made to the existing housing stock the UK average rating should generally improve over time.

Achieving an A-rating requires a great deal of forward planning and can be practical and cost effective for a new build but can be difficult to achieve in an older existing property even with a full, carefully planned 'retro-fit' (which is a Government scheme introduced to manage very high quality, whole house improvement projects).

There are different types of EPC Assessments for Domestic Buildings (RdSAP EPC), Commercial Buildings (SBEM EPC) and for New Buildings (SAP EPC).

Existing dwellings are assessed by a 'Domestic Energy Assessor' (DEA) but when a building is first created, it requires a much more detailed assessment called a SAP ASSESSMENT which in addition to producing an EPC Certificate also checks that the building complies with Part L of the Building Regulations and can only be conducted by an 'On Construction Energy Assessor' (OCDEA) or 'SAP Assessor.
