Guides
EPC guides for homeowners
Use these guides to read a certificate, understand its rating and decide what to check next. For a property’s official certificate, use GOV.UK. EPC Benchmark adds aggregate comparison context for homes in England and Wales.

Use comparison context
Have the certificate’s score?
Enter the score with a postcode district, property type and construction age band. The district, property-type, age and national views remain independent — they are separate comparisons, not one combined group.
Compare an EPC scoreAn aggregate comparison is not a survey, valuation, quote or guarantee about an individual home.
Find the official certificate
All address and certificate searches belong on the official government service. EPC Benchmark does not look up individual properties or certificates.
