What does a domestic energy assessor do?
A domestic energy assessor records the property information needed to produce an Energy Performance Certificate. The assessment focuses on the dwelling’s fixed energy-related characteristics rather than the current household’s personal energy use.
What is checked during an EPC visit?
The exact visit depends on the property, but relevant information can include dimensions, construction, insulation evidence, glazing, heating, heating controls, hot-water systems, fixed lighting and applicable renewable technologies. The assessor may take photographs and notes as evidence for the assessment and accreditation process.
How to prepare
Provide safe access to the heating system, controls, hot-water cylinder where present, loft hatch and other relevant areas. Keep documents available for insulation, extensions, replacement glazing, heating upgrades or other work that may not be fully visible.
What an EPC visit is not
It is not a structural survey, valuation, gas-safety check or electrical inspection. The purpose is to assess energy performance and produce the EPC.
Check for an existing certificate first
A domestic EPC in England and Wales is generally valid for 10 years. Search the official register before booking. If no valid certificate exists, or you need a newer certificate, send the property details for a quote.
