Quick answer: to find your EPC score, search the official energy-certificate register using your postcode or address. A domestic certificate shows a numerical energy-efficiency score and a band from A to G, plus a potential score based on modelled improvements.

How to check your EPC score online

  1. Open the official GOV.UK energy-certificate search.
  2. Search by postcode, street and town, or certificate number.
  3. Select the correct property address.
  4. Check the assessment date and whether you are viewing the current certificate.
  5. Read the current score, current band, potential score and recommendations.

Scotland has a different certificate service, so use the register appropriate to the property’s nation.

What does my EPC score mean?

BandScoreBroad interpretationA92+Highest energy-efficiency bandB81–91Very strong energy performanceC69–80Good performance for much of the existing stockD55–68Mid-range performanceE39–54Lower performance; important current rental thresholdF21–38Poor performanceG1–20Lowest energy-efficiency band

The number gives more precision than the letter. Two homes can both be D-rated but score 55 and 68, which puts them in very different positions relative to band C.

What is the potential EPC score?

The potential score is a modelled scenario showing what the property could achieve if the listed recommendations were completed as assumed. It is useful for understanding improvement potential but should not be treated as a guaranteed outcome or a specification for building work.

Why can’t I find my property?

Possible reasons include no certificate having been lodged, the certificate being outside the public search in a particular case, an address-format issue, or the property falling under another nation’s register. Try variations of the address and confirm the correct register.

When do I need a new EPC?

For homes in England and Wales, an EPC is generally valid for 10 years. You may need a new certificate when there is no valid EPC for a transaction that requires one. You may also choose a reassessment after significant upgrades if you want the official record to reflect them.

Can my score change after improvements?

Yes. If relevant property features change and a new assessment is carried out, the score can change. Keep evidence for hidden improvements because what the assessor can record is governed by methodology and accreditation rules.
