An EPC is a record of an energy assessment. Start with the certificate for the exact property, then read its date, assumptions and recommendations. An attractive rating alone does not tell you how the home will feel or what your bills will be.
What to check.
Check the certificate identity
Confirm the address, certificate date and whether you are viewing the relevant assessment. Ask the seller about changes made since the assessment.
Read the building assumptions
Compare the certificate’s description with what you see at the viewing. Keep questions about the heating system, insulation and extensions for the seller or assessor.
Check recommendations before budgeting
Get current quotations and advice about suitability before planning work. An indicative recommendation is not a contractor’s quote or confirmation that permissions are in place.
What the evidence cannot tell you.
Certificate estimates are not a forecast of your household’s bills. Occupancy, usage, tariffs and later changes matter. Letting requirements and exemptions need a separate check against the current rules.
