EPC Assessment Process: What Happens During a Home Energy Survey

During an EPC assessment, a qualified domestic energy assessor visits your property and collects data on its age, construction type, wall and roof insulation, windows, heating system, hot water, and lighting. The survey is visual and non-destructive — assessors do not drill holes or move furniture, though access to the loft, boiler, and meters is helpful.

The visit typically takes between 30 and 60 minutes depending on property size and complexity. After the visit, the assessor inputs the data into government-approved software to calculate the SAP score and produce the certificate. The completed EPC is lodged on the national register, usually within 24 to 48 hours of the assessment.
