The Non-Domestic EPC Register: How to Check a Commercial EPC

Every valid commercial EPC — an Energy Performance Certificate, the official energy-efficiency rating for a business building — is recorded on a free, public, government-run database: the non-domestic EPC register (“non-domestic” is simply the government’s word for commercial). If you’re buying, selling, letting or managing a commercial property in England or Wales, you can look up whether it has a current certificate, what the rating is and when it expires, in about two minutes, without asking anyone’s permission.

One thing up front, because plenty of websites blur it: we are not the register. The register is run by the government. We’re the accredited assessors who survey buildings and lodge certificates onto it. This page shows you how to use the official service properly, what everything on the certificate means — and what to do if your search comes back empty.

What is the non-domestic EPC register?

The register is the government’s official record of every non-domestic (commercial) EPC lodged in England and Wales, searchable through the “Find an energy certificate” service on gov.uk. It’s the authoritative source — the same record solicitors, lenders and agents rely on during a sale or lease — and it is completely free to search. Certificates can only be added (“lodged”) by accredited energy assessors through their government-approved accreditation schemes, which is what keeps the record trustworthy. Scotland and Northern Ireland keep separate registers — more on that below.

How to check a commercial EPC on the register — step by step

Go to the official “Find an energy certificate” service on gov.uk. Use the government page directly, not a look-alike site.

Choose the non-domestic option. The service covers homes and commercial buildings, and the two are held separately — if you search the domestic side for a shop, you’ll find nothing and wrongly conclude there’s no EPC.

Search by postcode, then pick the correct address from the list. Commercial addresses are often recorded oddly — “Unit 3”, “Ground Floor”, “Rear of 12” — so scan the whole list before deciding it isn’t there.

Or search by certificate reference number if you have one (it’s on the certificate itself, and often in lease or sale paperwork). This is the fastest route and sidesteps address problems entirely.

Open the certificate to see the energy rating, the valid-until date, the building details and the linked recommendation report.

Download or print it. The certificate is a public document — save a copy for your solicitor, agent or your own records, and note the reference number.

What the certificate page shows you

The energy rating — commercial EPCs run from A+ to G (A+ is reserved for exceptional, net-zero-or-better buildings; most stock sits in the C–E range). The band reflects the building’s modelled carbon emissions, not its energy bills.

The valid-until date — a commercial EPC lasts 10 years from lodgement.

The certificate reference number — the unique ID solicitors and agents quote in transactions.

Building details — address, total useful floor area and main heating fuel, which is worth sanity-checking against the real building.

The recommendation report — the suggested improvements lodged alongside every commercial EPC, grouped roughly by payback period.

The assessor’s details — who carried out the assessment and which accreditation scheme they belong to, so you can verify they were properly accredited.

What the rating actually means for you

The rating isn’t trivia — it decides what you can legally do with the building. Under MEES (the Minimum Energy Efficiency Standards), a commercial property generally needs a rating of E or better to be let, and that floor applies to existing leases, not just new ones — see our guide to the minimum EPC rating for commercial property. The government has also consulted on raising the bar much further over the next decade; our commercial EPC regulations 2030 page covers what’s proposed and what landlords should do about it. So if the register shows an F or G — or a scraped-through E — you’re looking at a compliance problem, and the recommendation report is the sensible starting point for fixing it.

No commercial EPC on the register? Here’s what it means

An empty search usually comes down to one of five things:

No EPC has ever been lodged. Common where the building hasn’t been sold or let in the last decade — there was simply never a legal trigger.

An old certificate has expired. Expired certificates drop out of a standard search once past their 10-year life.

You searched the wrong category. Domestic and non-domestic certificates live in separate lists — this is the single most common mistake.

The address is recorded differently. Try the postcode-only search and read the whole list, or use the certificate reference number.

The owner has opted out of public display (see below) — the certificate exists but doesn’t appear in searches.

If there genuinely isn’t a valid EPC and you’re about to sell or let the property, you’ll need one — it’s a legal requirement, and a missing certificate can stall a transaction at exactly the wrong moment (our commercial EPC requirements guide covers when the duty bites, and the exemptions that occasionally apply). That’s the point at which we can help: accredited assessors, a fixed fee agreed up front, UK-wide, with the new certificate lodged on the register for you.

Nothing on the register — or a certificate about to expire? Request a fixed-fee quote and we’ll survey the building and lodge a new commercial EPC.

Expired or about to expire?

There’s no duty to renew a commercial EPC the day it expires — the legal requirement bites when you next sell, let or renew a lease. But waiting has a cost: if the old certificate was a marginal E and the building hasn’t improved, a fresh assessment could land at F and block the letting under MEES. If your certificate is inside its final year and a transaction is even possible, renewing early — with time to act on the recommendations — is the cheap version of the problem.

Opting out: why some certificates don’t show

Building owners can ask for their certificate to be withheld from public view on the register. An opted-out EPC is still valid, still lodged and still satisfies the law — it just won’t appear when third parties search. If you’ve opted out and can’t find your own certificate, the reference number on your copy still identifies it, and the opt-out can be reversed through the register service. Worth knowing before you conclude a building has no EPC: absence from the search isn’t absolute proof of absence.

Scotland and Northern Ireland: separate registers

The gov.uk service covers England and Wales only. Scotland has its own EPC register and its own rules for non-domestic buildings (including a separate regime for larger buildings under Section 63 of the Climate Change (Scotland) Act), and Northern Ireland runs its own register too. If your property is in Scotland or NI, search the relevant national register rather than gov.uk — the certificates and the compliance rules differ, so don’t assume the English position applies.

A warning about look-alike “EPC register” websites

Search results for register terms attract third-party sites styled to look official, some of which charge for information the government publishes free. The rule is simple: the only official register is the government’s, and searching it costs nothing. And to repeat our own disclosure — this site isn’t the register either. We’re an assessment service: when a building needs a new certificate, we survey it, produce the EPC and lodge it on the official register. Checking what’s already there needs nobody’s help but gov.uk’s.

Request a fixed-fee quote — tell us the property type, rough floor area and postcode, and we’ll confirm a fixed price for a new commercial EPC, lodged on the register.
