What an EPC is in one paragraph
An Energy Performance Certificate (EPC) is a standardised UK document that rates how energy efficient a Property is likely to be, with headline bands from A to G, and that records recommended improvements where the methodology lists them. For domestic properties in England and Wales, certificates are lodged on the official EPC Register when a valid assessor produces one. It is a regulatory and market information tool — not a warranty that your bills will match the model, and not a substitute for a structural survey.
Why buyers and tenants still read EPCs carefully
Even where an EPC is “only” regulatory, it is often the fastest place to see fabric and services clues: approximate age of assessment, main heating system, hot-water approach, and wall or roof insulation fields where recorded. That helps you ask better questions before you spend on surveys and helps Owners prioritise retrofit that may affect Completion Score style readiness conversations.
How Property Passport UK uses EPC data
Property Passport UK can surface EPC-linked fields alongside other official layers (for example flood and title-related context) so Stakeholders see one structured record. The authoritative certificate remains the lodged EPC; if fields conflict, treat the register and your professionals as decisive.
