Access the assessor needs
The assessor must visit every habitable room, inspect the boiler and hot water cylinder, check loft insulation if accessible, and read electricity and gas meters where present.
Clear access to the loft hatch, airing cupboards and under-stair cupboards. If rooms are locked, the assessor cannot record them accurately.
- All rooms including extensions and conversions
- Boiler, controls and hot water storage
- Loft hatch and visible insulation
- Windows, radiators and fixed lighting
Documentation that helps
If you have invoices or certificates for cavity wall insulation, double glazing, a new boiler or solar panels, have them ready. Documentary evidence can improve accuracy when the assessor can verify installation dates.
Planning approval for extensions helps the assessor understand the property layout.
Timing your booking
Book early if you are marketing a property — agents need the EPC reference for listings. Compare local assessors on EPCguys and allow time for quotes and scheduling.
