How to Check Your EPC Certificate: Find Your Rating in Under a Minute (2026 Guide)

Written by the Frank EPC team of accredited Domestic Energy Assessors (DEAs). Last updated September 2026.

The short answer

To check your EPC certificate in England, Wales or Northern Ireland, go to the free government register at gov.uk/find-energy-certificate, choose a domestic certificate, enter your postcode and select your address. The results show your energy rating and the expiry date, and you can open the full report to see the recommendations. It is free, it takes under a minute, and you do not need to create an account. If no certificate appears, or the one you find has expired, you need a new assessment from an accredited assessor before you can market the property for sale or let.

Frank EPC covers the whole county, and you can book an EPC in Berkshire online in about two minutes.

How do I check the EPC for my house?

Five steps, and the whole thing is free.

1. Go to the official register. Visit gov.uk/find-energy-certificate and select Start now. This is the government service for England, Wales and Northern Ireland. Scotland has its own separate register run by the Scottish EPC Register.
2. Choose the right certificate type. Pick domestic for a house, flat or maisonette. Pick non domestic for a shop, office or other commercial building.
3. Search by postcode. Enter the property postcode and select Find. You can also search by the report reference number (RRN) if you already have one, which is the 20 digit number printed on an existing certificate.
4. Pick your address from the list. Each result shows the band, the score and the expiry date, so you can often answer your question without opening anything.
5. Open the certificate. The full report gives you the current and potential rating, the estimated energy costs, and the recommended improvements with indicative costs and savings.

Two things worth knowing before you start. First, EPCs are public documents. Anyone can look up any address, which is exactly why buyers, tenants and estate agents check yours. Second, the register only holds certificates lodged from 2008 onwards, because that is when EPCs were introduced. A pre 2008 property that has never been sold or let since then may have nothing on file at all.

Can I check an EPC rating by postcode for free?

Yes. The GOV.UK register is free, unlimited and open to the public. You do not need to own the property, prove anything, or pay for a login.

You will find plenty of third party sites offering an “EPC register check” or an “EPC lookup”. They are pulling the same open government data, sometimes formatting it more attractively, and occasionally trying to sell you something at the end. There is nothing wrong with them, but there is no information on those sites that is not on the free official register, so start there.

Here is how the main routes compare.

Where you check	Cost	Covers	Best for
GOV.UK Find an Energy Certificate	Free	England, Wales, Northern Ireland	Almost everyone
Scottish EPC Register	Free	Scotland only	Scottish properties
Third party EPC lookup sites	Usually free	Same open data	Nothing the official register cannot do
Your estate agent or solicitor	Free	The property they are handling	Confirming what is already on file for a sale
Your own paperwork or email	Free	Your property	Finding the RRN quickly

What does the expiry date on my EPC mean?

An EPC is valid for 10 years from the date it was lodged, not from the date of the survey visit and not from the date you moved in. Once the register shows an expiry date in the past, that certificate can no longer be used to market a property for sale or to let.

There is a common misunderstanding here that costs people money. An expired EPC does not need replacing simply because it expired. If you are not selling, not letting and not applying for a grant scheme that requires one, you can leave it. The trigger is the transaction, not the date. Our guide on how long an EPC lasts covers the renewal timing in full.

The opposite mistake is more expensive. Sellers routinely discover on the day they want to list that their certificate ran out three years ago, then lose a week of marketing time. If you are thinking about moving in the next six months, check the register now rather than the week your agent takes photographs.

Why can I not find my EPC on the register?

Six common reasons, in roughly the order we see them.

• The property has never needed one. No sale, no letting and no new build since 2008 means there may be nothing to find.
• The address is recorded differently. Flats are the usual culprit. Try “Flat 2” instead of “2A”, search the whole postcode and scroll, and check for the building name as well as the street number.
• It was lodged against a former plot or site address. New builds are often lodged before the street naming is finalised, so search the developer’s plot number or the postcode alone.
• The owner has opted out. Owners can ask for their address to be removed from public display on the register. The certificate still exists, but it will not show in a public postcode search.
• It is genuinely expired and dropped out of your search filter. Expired certificates still appear, so if you see nothing at all, the property is more likely in one of the categories above.
• The assessor never lodged it. Rare, but it happens. If you paid for an EPC and it is not on the register, you did not get what you paid for, and the accreditation scheme named on your paperwork is the place to raise it.

If you have searched properly and there is nothing there, the answer is simple. You need a new assessment. Our guide on how to get an EPC certificate walks through the booking process, and you can book an accredited EPC assessment with us directly.

What if the EPC on the register is wrong?

This matters more than most homeowners realise, because the certificate on the register is the one buyers, tenants and lenders see, not the improvements you know you have made.

The most common cause is an assessment where the assessor could not verify something. An EPC is a visual survey fed into the government approved RdSAP model, and anything that cannot be seen or evidenced gets a default assumption. Defaults are conservative, so undocumented cavity wall insulation, a newer boiler or upgraded glazing can all leave you with a lower band than the house deserves.

The route to fix it:

1. Contact the assessor who produced it. Their name and accreditation scheme are printed on the certificate. Put it in writing, say specifically what you think is wrong, and give them a few days to reply. If they agree, they can amend and re lodge the certificate, usually within a week or two.
2. Escalate to the accreditation scheme. If the assessor does not respond, disputes it, or is no longer trading, the scheme named on the certificate handles the complaint. Where an error is confirmed, a corrected certificate must be lodged, and this should not cost you anything.
3. Or commission a fresh assessment. You can pay for a new EPC from a different assessor at any point. The new certificate supersedes the old one on the register. This is often the quickest route when the original is old, the property has genuinely changed since, or you simply want the improvements reflected.

One practical tip that saves people a rebooking. Before any assessment, gather the paperwork: cavity wall insulation guarantee, boiler installation certificate, FENSA or CERTASS glazing certificates, loft insulation invoices, solar panel MCS documents. Show the assessor the evidence and the model uses your real figures instead of a pessimistic default.

Do I need to check my EPC before selling or letting?

Yes, and it should be the first thing you do, before the agent visit and before the photographs.

Selling. A valid EPC must be commissioned before the property goes on the market, and the rating has to appear in the advertising. Our seller’s guide to EPCs sets out the full requirement.

Letting. The same commissioning rule applies, plus the property must be rated band E or above, and the certificate has to be given to the tenant free of charge. From 1 October 2030 privately rented homes in England and Wales will need to reach the equivalent of band C, subject to a cost cap. Our landlord guide to EPC requirements has the detail.

Remortgaging or applying for a green mortgage product. Some lenders reference the EPC band when pricing a deal, so a certificate showing an out of date band can cost you real money.

Is the EPC rating system changing?

Yes, eventually, and it is worth knowing where things stand so you are not caught out by headlines.

The assessment methodology already changed. RdSAP 10 took effect on 15 June 2025 and now underpins every new domestic EPC. It handles heat loss for flats and mid terraced homes more fairly than the old version, so some properties score differently under it than they did on a certificate lodged before that date.

The bigger reform, which replaces the single A to G cost based rating with multiple headline metrics under the Home Energy Model, has been pushed back. The government confirmed in March 2026 that it will not launch in October 2026 as planned and will now arrive in the second half of 2027, with the exact date to be agreed. Nothing you need to do differently today, but if your certificate is old and you are approaching a sale or the 2030 rental deadline, there is a reasonable argument for getting reassessed under the current methodology rather than waiting for a system nobody has seen yet.

Checking your EPC in Berkshire

Frank EPC works across Reading, Bracknell, Slough, Windsor, Wokingham, Maidenhead, Newbury and the surrounding villages. Much of the county’s housing stock is 1930s to 1980s, which is exactly the range where old certificates and default assumptions tend to undersell a property.

Our advice is boring but it works. Check the free register first. If you already have a valid certificate, keep it and save your money. If it has expired, is missing, or shows a band that clearly ignores the work you have done, book an EPC assessment and get an accurate one lodged. If you are local to us, our EPC Bracknell page has same day and next working day availability, and our Berkshire EPC price guide sets out typical 2026 fees before you commit to anything.

Frequently asked questions

How do I check my EPC certificate? Go to gov.uk/find-energy-certificate, choose a domestic certificate, enter your postcode and select your address. The result shows your band, score and expiry date, and you can open the full report free of charge.

Can I check an EPC by postcode? Yes. The GOV.UK register lets you search any postcode in England, Wales or Northern Ireland for free. Scotland uses a separate Scottish EPC Register.

Is checking an EPC free? Yes. The official register is free and needs no account. Third party lookup sites use the same open government data.

Are EPC certificates public? Yes. Any lodged EPC is publicly searchable by address, unless the owner has asked for the address to be withheld from public display.

How far back does the EPC register go? To 2008, when EPCs were introduced in England and Wales. A property with no sale or letting since then may have no certificate at all.

Why is my EPC not showing on the register? Usually because the property has never needed one, the address is recorded in a different format, it was lodged against a plot or site address, the owner opted out of public display, or the assessor never lodged it.

How do I get my EPC corrected? Contact the assessor named on the certificate in writing first, then escalate to their accreditation scheme if it is not resolved. A confirmed error must be corrected at no cost to you. Alternatively, commission a new assessment, which supersedes the old certificate.

Does an expired EPC need replacing straight away? Only if you are selling, letting or need one for a grant or lender requirement. The trigger is the transaction, not the calendar date.
