Methodology
To assess the energy performance of your property an energy assessor needs to visit the property and will:
- establish the age of the property along with the age of any extensions that may have been added
- measure the property to establish the heat loss perimeter
- enter the loft (if possible) to measure any loft insulation present
- make a note of the method of heating the property and the water
- check for energy efficient light bulbs in fixed light fittings
This data is then enterered on to a system which uses a Reduced Data Standard Assessment Process to produce a certificate showing a grade from A to G.
The visit normally takes about an hour and it is helpful if the owner or a representative is present but this is not always necessary.
