Check a property's EPC rating
An Energy Performance Certificate scores a property from A to G based on a 1–100 point scale, and it matters more every year: buyers ask about running costs, lenders price efficiency into some mortgages, and landlords face the government's announced EPC C policy for 2030. Address Lens shows a matched current EPC record where one is available for an address in England or Wales, alongside the property's sold price history and risk screening.
What the EPC check shows
- Current rating and score — the band (A–G) and the underlying points.
- Potential rating — what the assessor calculated the property could reach.
- Expiry date — certificates usually last ten years. A valid EPC is generally required when a property is marketed for sale or let, subject to exemptions and current government guidance.
- Recommendations — the assessor's measures list, the starting point for any upgrade plan.
- Floor area and property details recorded at assessment.
How to check an EPC
- Search the postcode, full address including its postcode, or UPRN.
- Open the property's report — the EPC card shows the rating, score, expiry and recommendations.
- If you're a landlord, screen the rating against the announced 2030 rules — see our EPC C by 2030 guide.
What does an EPC assessor check?
A domestic EPC comes from a visual, non-invasive survey by an accredited domestic energy assessor — typically 30 to 60 minutes on site. The assessor records the property's construction and age, loft and wall insulation, heating system and controls, hot water, windows and glazing, lighting, and measured floor area, then lodges the certificate on the national register.
Frequently asked questions
How long does an EPC last?
A certificate normally remains valid for ten years from issue, unless a newer assessment replaces it. The expiry date is printed on the certificate and shown on the register.
My EPC was issued in 2020 — is it still valid?
A certificate issued in 2020 normally remains valid for ten years, so until 2030, unless a newer assessment has replaced it. Check the expiry date on the certificate or the register entry.
Do I need an EPC to sell my house?
A valid EPC is generally required when a property is marketed for sale or let, subject to exemptions and current government guidance — commission one from an accredited assessor before marketing if the register has no valid certificate.
