Landlord EPC check: how it works

Rules checked 1 November 2026. Back to the landlord EPC check.

Finding each home

For each line you type, we read the postcode at the end and look up every certificate at that postcode, keeping the latest for each home. We then pick the one whose address contains everything else you typed. Numbers have to match exactly, so 19 doesn’t find 119; words can be shortened, so “St” finds “Street”. If more than one home matches, you choose. If none does, the home may have no certificate, or be registered under a different address.

Today’s minimum

A privately rented home in England and Wales must be rated E or better unless the landlord has registered an exemption. Certificates last 10 years; we show the last valid day as ten years from registration, less a day, which is how GOV.UK shows it. An expired certificate doesn’t end a tenancy, but you need a valid one before the next.

The 2030 standard

The government’s January 2026 response confirmed that every tenancy must meet the higher standard by 1 October 2030, with no earlier date for new tenancies. A home rated C or better on a certificate before 1 October 2029 counts as compliant until that certificate expires. Other homes will be judged on the new EPC measures, which a certificate today doesn’t show, so we give the gap to band C as a guide: band C starts at a score of 69. Landlords must spend up to £10,000 per home, less for homes worth under £100,000, before a cost exemption applies. The regulations are expected to come into force in 2027.

Filling it in from your energy certificate

In England and Wales you can find the home’s Energy Performance Certificate by postcode. The lookup uses the Ministry of Housing, Communities and Local Government’s energy performance of buildings data and shows the latest certificate for each home at the postcode. For each home the check shows the band, score, registration date, home type and main heating, and links to the full certificate on GOV.UK, which lists the improvements the assessor recommended. Your list of homes never leaves the page, and the CSV download is made on your device.

The postcode, and then the certificate number, go to our server, which asks the register and sends back only the fields the calculator uses. We don’t store or log any of it; the privacy policy has the detail. A certificate models a typical household in the home as it was when assessed, so it’s a starting point: your own bills or meter readings are better if you have them. Using it is optional.

What this isn’t

A guide, not legal advice. It doesn’t know about exemptions you’ve registered, and a certificate describes the home when it was assessed. The government’s landlord guidance has the full rules.
