How to Check an EPC on the Register

The quickest way to check a property's Energy Performance Certificate (EPC) is the "Find an energy certificate" service on GOV.UK for properties in England and Wales, or the Scottish EPC Register for properties in Scotland. Search by postcode or by the certificate's report reference number (RRN), and the result shows the current rating, the expiry date, and a link to the full recommendations report.

This matters more than it sounds, because an EPC that has lapsed, or one that was never registered correctly in the first place, can stop you marketing a property to let at all. Before you rely on any certificate, whether one a previous owner left in a drawer or one your letting agent mentions in passing, it is worth checking the register directly rather than taking the paper copy at face value.

Why check the register rather than the paper copy

A paper or PDF certificate can be out of date, belong to a different flat in the same building, or simply be wrong if it was issued for an earlier layout that has since changed, for example after a loft conversion or an extension. The register is the authoritative source, since every EPC assessor is legally required to lodge the certificate there once it is issued.

Checking the register also confirms three things a paper copy alone cannot always prove: that the certificate is genuinely current (not expired), that it applies to the exact property you are letting rather than a similar one nearby, and that no more recent certificate has since superseded it. All three matter if you are buying a property, taking over a management agreement, or simply have not checked your own portfolio's EPCs in a while.

How to search the register

By postcode. Go to the GOV.UK "Find an energy certificate" service and enter the property's postcode. This returns a list of every certificate registered at that postcode, including flats within the same building, so check the full address carefully rather than assuming the first result on the list is the correct one. Flats in converted or purpose-built blocks are the most common source of confusion here, since several units can share a postcode with only the flat number differing.

By certificate number. Every EPC carries a 20-digit report reference number, printed near the top of the certificate. Entering this number returns the exact certificate rather than a list to filter through, which is the more reliable method if you already have a copy of the certificate and just want to confirm it is genuine and still valid.

For Scotland. Properties in Scotland are not on the GOV.UK register. Use the Scottish EPC Register instead, searching by postcode or report reference number in the same way. The rating bands and 10-year validity period work the same way as in England and Wales, but the two registers are entirely separate systems, so a Scottish property will not appear on the GOV.UK search.

For Northern Ireland. Northern Ireland runs its own register, accessed via the relevant Northern Ireland government energy performance service rather than the GOV.UK or Scottish tools.

As a worked example, a landlord taking on a new two-bedroom flat from a previous owner would search the postcode, check the address line matches the exact flat number on the sales particulars, confirm the rating meets the current minimum for letting, and note the expiry date before relying on that certificate to market the property.

What the register shows you

Once you find the right certificate, the register page shows the current energy rating (A to G), the date it was issued, the date it expires (10 years after issue), and a link through to the recommendations report, which lists specific improvements the assessor identified for that property. It also shows the assessor's name and accreditation scheme, which is useful if you ever need to query how a rating was reached.

If the certificate on the register has already expired, or does not exist for the property at all, that is your answer: you need a new EPC assessment before marketing the property to let, regardless of what a paper copy in a filing folder says.

If the register shows no valid certificate

Occasionally a search returns nothing, even for a property you are fairly confident has been let before. This can happen for a genuinely new property that has never had an EPC issued, a property where the previous certificate has expired and dropped off the current listing view, or simply a search entered slightly differently from how the address is recorded on the register.

Before assuming a certificate never existed, try searching with a slightly different version of the address, for example the building name instead of the street number, or a neighbouring postcode if the property sits right on a postcode boundary. If a genuine search across a few variations still returns nothing, you will need to book an assessment with an accredited domestic energy assessor before marketing the property, since there is no shortcut around having a valid, registered EPC in place.

Checking a certificate when buying a property

If you are buying a property to let out, checking the register before completion, rather than relying solely on the certificate the estate agent has on file, is worth the two minutes it takes. Sales particulars sometimes quote a rating from an EPC that has since expired, or, less often, reference the wrong certificate entirely if a property has been on the register more than once, for example after a previous refurbishment triggered a new assessment. Confirming the rating and expiry date independently before you rely on it for your own letting plans avoids finding out only after exchange that the certificate you were shown is not the current one.

Common mistakes

A few things trip landlords up when checking the register:

• Searching an old or slightly different address. Postcodes that have been reassigned, or flats listed under a building name rather than a number, can return no results even though a valid certificate exists. Try searching a nearby, definitely-correct postcode if your first search comes back empty.
• Assuming a neighbouring flat's certificate applies to yours. Even identical-looking flats in the same block can have different ratings, particularly if one has been refurbished more recently than another.
• Treating an expired certificate as still valid because the property "hasn't changed." The 10-year expiry applies regardless of whether any work has been done to the property, so an unexpired-looking certificate can still have quietly passed its date.
• Confusing a new build's predicted rating with its as-built EPC. New builds are marketed with a provisional rating before completion; the on-completion EPC, based on the finished property, is the one that governs letting and can differ from the prediction.

How Property HQ helps

Property HQ tracks every property's EPC rating and expiry date alongside your gas safety, EICR and licensing certificates, so you get a reminder well before a 10-year-old EPC lapses rather than finding out mid-marketing that a certificate has expired. See our EPC requirements guide for the current minimum standard and exemption rules, and our guide to improving an EPC rating if a check on the register shows your property is close to, or below, that minimum. Our landlord certificates checklist covers how EPCs fit alongside the other certificates most portfolios need to track.
