An EPC assessment costs between £35 and £120 for most UK homes in 2026, with the average sitting around £60 to £80. Flats and smaller terraces are cheapest; detached houses and London properties cost more. You might not need to pay at all if you qualify for a grant scheme like ECO4 or Warm Homes: Local Grant, which often include a free EPC as part of the process.
What Is an EPC and Why Do You Need One?
An Energy Performance Certificate rates your home from A (most efficient) to G (least efficient). Every home in England and Wales needs one before it can be sold or rented, and the certificate lasts 10 years. That's the legal bit. But here's why it actually matters beyond ticking a box: your EPC rating determines which government grants you can access, and some of the best schemes are specifically designed for homes rated D or below.

If you're a homeowner with no plans to sell, you're not legally required to get one. Nobody's going to knock on your door and demand it.
But getting one anyway is often worth the £60 to £80. The certificate comes with a recommendations report listing upgrades ranked by cost and impact, and more importantly, a low rating can open the door to fully funded insulation, heating upgrades, or both through schemes like ECO4. We've covered what each EPC band qualifies you for separately, and it's worth a look before you decide whether to bother.
Landlords are in a different position. Since April 2020, rental properties in England and Wales must have a minimum E rating, and the government has been consulting on raising that to C, though the timeline keeps shifting. If you're letting a property, you need a valid EPC. No exceptions.
How Much Does an EPC Cost in 2026?
£60 to £80. That's what most homeowners actually pay.
The official price isn't regulated, so assessors set their own rates. This creates a surprisingly wide range. We've seen quotes as low as £35 for a one-bed flat in Sheffield and as high as £120 for a five-bed detached in central London. The certificate itself costs the same to lodge with the government (there's a small registration fee the assessor pays to the accreditation body), but the labour cost of the visit varies enormously based on where you live and how big your home is.
Here's a rough guide based on what we see across the market:
Property type
Typical cost
1-2 bed flat
£35–£55
2-3 bed terraced house
£50–£70
3-4 bed semi-detached
£60–£85
4-5 bed detached
£75–£120
Those figures include the assessment visit and the lodging of the certificate on the national register. You shouldn't be charged extra for the certificate itself, and if an assessor tries to add a "registration fee" on top, that's a red flag.
One thing worth knowing: online-only EPCs don't exist. Anyone offering to produce an EPC without visiting your property is either breaking the rules or running a scam. The assessor has to physically inspect your home, measure rooms, check your boiler, look at insulation levels, examine windows and walls. There's no legitimate shortcut.
What Affects the Price of an EPC Assessment?
So why does the same certificate cost £35 in one postcode and £110 in another?
Location is the biggest factor. London and the South East are consistently more expensive, partly because assessor overheads are higher and partly because demand is stronger. In cities like Manchester, Birmingham, and Leeds, competition between assessors tends to push prices down. Rural areas can go either way: sometimes you'll find a local assessor who charges less than the urban average, sometimes you'll pay a premium because the nearest qualified person has to drive 40 minutes to reach you.
Property size matters too, but less than you'd think. A one-bed flat takes about 30 to 45 minutes to assess. A four-bed detached might take 60 to 90 minutes. The difference in assessor time is real but modest, which is why the price gap between a flat and a large house is typically £30 to £50, not hundreds.
Then there's access. If the assessor can't see your loft hatch, can't get to the boiler, or can't check the cavity walls, they have to make assumptions. Those assumptions tend to be conservative (they'll assume the worst), which can drag your rating down. This doesn't change the price, but it can change the result, so it's worth clearing access before the visit.
Honestly, the biggest variable is just which assessor you pick. Some charge a premium because they're established and busy. Others undercut because they're building a client base. The certificate is the same either way, as long as they're properly accredited.
Can You Get a Free or Reduced-Cost EPC Through a Grant Scheme?
Yes, and this is the bit most people miss.
If you're applying for a government energy efficiency grant, the scheme will often cover the cost of the EPC assessment as part of the process. ECO4, which funds insulation and heating upgrades for eligible low-income households, typically includes a free EPC when your home needs one. The installer or scheme coordinator arranges it, and you don't pay.
The Warm Homes: Local Grant works similarly. Local authorities running this scheme often send an assessor to your home as part of the initial eligibility check, and the EPC comes out of the grant funding rather than your pocket.
So if you think you might qualify for either scheme, it's worth checking eligibility before paying for an EPC yourself. You could save £60 to £80 and get the upgrades funded too.
A quick note on the Great British Insulation Scheme: that closed in March 2026. If you see older articles suggesting GBIS will cover your EPC cost, that's out of date. Our guide to what replaced GBIS has the current picture.
For homeowners who don't qualify for grant schemes, there's no subsidy or discount programme for EPCs specifically. You'll pay the full price. But if your home ends up with a D or E rating, the grants you can then access are worth far more than the cost of the assessment. We've written detailed guides on what's available for D-rated homes and E-rated homes if that's where you land.
How to Find an Accredited EPC Assessor in the UK
Right, so you've decided to get one done. Here's how to avoid overpaying or picking someone dodgy.
Every EPC assessor in England and Wales must be accredited through one of the government-approved schemes: Elmhurst Energy, Quidos, Stroma, or ECMK. You can verify any assessor's credentials on the EPC Register, which is the official government database. If they're not on there, walk away.
The quickest way to find an assessor is through the EPC Register itself (epcregister.com). Enter your postcode and it shows accredited assessors in your area. You'll get names, contact details, and you can compare.
But here's what most guides won't tell you: the cheapest assessors on comparison sites are sometimes cheap for a reason. They're rushing through assessments, spending 20 minutes in a four-bed house, and making assumptions that tank your rating. A good assessor takes their time, asks about improvements you've made, and checks everything properly. The difference between a rushed D rating and a properly assessed C rating could be worth thousands in grant eligibility or property value.
Some practical tips:
Get 2-3 quotes. It takes five minutes and can save you £30 to £40.
Ask how long the visit will take. If they say "15 minutes" for a three-bed semi, be suspicious.
Check recent reviews. Google reviews or Trustpilot ratings for local assessors are surprisingly useful.
Ask whether the price includes lodging the certificate. It should, but confirm.
Local Facebook groups are actually a decent source for assessor recommendations, weirdly enough. People in your area have used someone recently and will tell you exactly what they paid. Mumsnet too, though you'll have to wade through some tangential discussions about school catchment areas to find it. Anyway.
What Happens After Your EPC Assessment?
The assessor visits, measures everything, photographs your boiler and insulation, and leaves. You don't need to do anything during the visit beyond letting them access the loft, the boiler, and external walls.
Within a few days (sometimes within 24 hours), your certificate gets lodged on the national EPC Register. You'll receive a copy showing your current rating, your potential rating if you made all the recommended upgrades, and a list of those recommended improvements ranked by estimated cost and impact.
That recommendations page is genuinely useful. It'll tell you things like "adding 270mm of loft insulation would cost approximately £300 to £600 and improve your rating by one band." If that kind of upgrade interests you, our guide to improving your EPC rating ranks the cheapest upgrades first so you can see where to get the most bang for your money.
Your certificate is valid for 10 years. You don't need to renew it unless you want to, though if you've made significant improvements (new boiler, insulation, solar panels), getting a fresh EPC makes sense because the better rating could qualify you for different schemes or add value if you're selling.
One thing to watch: if you're applying for a grant scheme and your existing EPC is more than a couple of years old, the scheme may require a new assessment anyway, particularly if you've already had work done. Check with the scheme coordinator before paying for a new one yourself.

Frequently asked questions
Do I legally need an EPC if I'm not selling or renting?
No. There's no legal requirement for owner-occupiers to have an EPC unless you're selling or renting the property. But getting one can qualify you for grants worth thousands, so it's often worth the £60 to £80 even if you're staying put.
Can I use an EPC from a previous owner?
Yes, as long as it's less than 10 years old and still on the register. You can check at epcregister.com by entering your postcode. Bear in mind it won't reflect any improvements you've made since buying, so if you've upgraded the boiler or added insulation, a new assessment would give you a more accurate (and probably better) rating.
How long does an EPC assessment take?
Between 30 minutes and 90 minutes depending on property size. A two-bed flat is usually done in half an hour. A large detached house takes longer.
Why is my EPC quote so much cheaper than my neighbour's?
EPC prices aren't regulated, so assessors set their own rates. Competition, location, and how busy they are all play a part. A cheaper quote isn't automatically worse, but if someone is offering to assess a four-bed house in 15 minutes for £35, they're probably cutting corners. That can mean a lower rating than you deserve, which could cost you grant eligibility. Get 2-3 quotes and ask how long the visit will take before booking.
Is an online EPC legitimate?
No. An assessor must physically visit your property. Any service offering an EPC without a home visit is not producing a valid, legally recognised certificate.
