To receive an EPC, you must have an Energy Assessment Survey (EAS) carried out at your property. Your Domestic Energy Assessor will perform internal and external inspections to determine how energy efficient your property is. They will also assess if it is possible to increase the level of efficiency, and what actually needs to be done to do so.
Some of the things your assessor will take a look at are:
- Windows
- Roofs, walls and insulation
- Boilers and heating systems
- Renewable energy devices (solar panels or wind turbines)
- Lighting
- Fireplaces
- The building measurements
- The year the property was built
You can find the list of approved assessor in your area here. All assessors are following a strict set of rules how to assess each property, therefore there is very little room for variation. As long as the assessor of your choice is officially accredited, you’re good to go. Most people choose their EPC assessor by their location.
Once your assessor has performed a full inspection, they will put together your EPC and grade your property’s energy performance: A being the most efficient and G being the least.
