EPC When Selling a House: Rules, Cost and Ratings (2026 UK)

By Lisa Hayes · 20 October 2026

Yes. In England, Wales and Northern Ireland you need a valid Energy Performance Certificate (EPC) to market and sell your home, it lasts ten years, and there is no minimum rating you must hit to sell. Trading Standards can issue a £200 penalty if you market without one, but the bigger cost is delay: your conveyancer will want it on file before the sale can move. A typical EPC costs somewhere around £60 to £120, so it is one of the cheapest bits of the whole process, and one of the most commonly left to the last minute.

• 10 yearshow long an EPC stays valid
• 7 daysto have one available once marketing starts
• £200penalty for marketing without one
• Noneminimum rating needed to sell

I have lost count of the sales that wobble over a piece of paper that takes a surveyor-type about 45 minutes to produce. So this guide goes through everything a seller actually asks about EPCs: the law, the cost, how the rating is worked out, what to do when you disagree with it, whether upgrades are worth it before selling, how it all differs if you are selling to a cash buyer, and what the government's delayed reforms mean for you right now.

Do you legally need an EPC to sell a house?

Yes, with a few narrow exceptions covered below. If you are selling in England, Wales or Northern Ireland, you must make an EPC available to prospective buyers free of charge. Citizens Advice puts the practical deadline plainly: you, and anyone acting for you such as an estate agent, must try to have one available within 7 days of the property first going on the market. Since January 2013 the energy rating has also had to appear in the advert itself, which is why you will see that little coloured bar on every Rightmove and Zoopla listing.

The rule applies to the marketing stage, not just completion. That matters because plenty of sellers think of the EPC as a conveyancing formality that can wait until there is a buyer. It cannot. An agent who puts your house online without one is leaving you exposed, and a good agent will refuse to list until the assessor has been booked.

Scotland runs its own regime. If you are selling north of the border, the EPC is bundled into the Home Report that a seller must commission before marketing. Scotland is also running its own EPC reform programme, so check the Scottish Government's pages rather than relying on England-focused guidance. Our guide to selling a house in Scotland covers how the Home Report fits in.

What happens if you sell without an EPC?

Two things, one theoretical and one very real. The theoretical one is the penalty: Trading Standards (your local authority) can issue a penalty notice of £200 per dwelling where an EPC was required and not provided. I have rarely heard of it being enforced against ordinary private sellers, and I would not build a plan around that.

The real one is friction. Your buyer's solicitor will ask for the certificate as part of the contract pack, your mortgage lender's valuer may note the rating, and a missing EPC is one of those small things that makes a sale feel disorganised. Disorganised sales get re-negotiated. If the buyer is already nervous, a three-day scramble for an assessor is exactly the kind of thing that gives them room to wobble. Order it when you decide to sell. Not when you accept an offer.

How long does an EPC last, and can you reuse an old one?

Ten years from the date of issue, and you can use the same certificate for as many sales or lettings as you like within that period. Before paying anyone, search the free government register (the "find an energy certificate" service) using your postcode or address. If your house was sold, let or remortgaged with a new-build, a government scheme or a green improvement in the last decade, there may well be a valid certificate sitting there already.

You will need a new one if:

• there has never been one for the property,
• the existing one is more than ten years old,
• you have made substantial changes, such as an extension, a new heating system, solar panels or serious insulation work, and you want the record to reflect them.

How much does an EPC cost?

Prices are set by the assessor and vary by region and property size. Commonly quoted figures run from roughly £60 to £120, with London and the South East at the upper end, and larger or more complicated homes costing more. A visit takes between 30 and 60 minutes for a typical house and the certificate usually lodges on the register within a few days.

Be sceptical of anything dramatically cheaper than the local going rate, and equally of an agent who offers to "arrange it" and quietly adds a margin. You can book an accredited domestic energy assessor yourself. Ask whether they are registered with a government-approved accreditation scheme, and whether the fee includes lodging on the national register. It should.

What does an EPC assessor actually look at?

A domestic energy assessor does not take the house apart. They measure and photograph, and ask questions. The main things they record:

• Size and shape: floor areas, number of storeys, extensions, whether the property is detached, semi, mid-terrace or flat.
• Walls: solid brick, cavity, stone, timber frame, and whether there is any insulation. Cavity fill is hard to see, so the assessor relies on evidence or the age of the property.
• Roof and loft: loft insulation depth, whether the loft is boarded, and the type of roof.
• Windows and doors: single, double or triple glazing and its approximate age.
• Heating and hot water: boiler type and age, heating controls, radiators, cylinder insulation, and any renewables.
• Lighting: the proportion of low-energy fittings.
• Floors: solid or suspended, and insulation if visible.

That data goes into a standard model (known as RdSAP for existing homes) which produces both a numerical score and the A to G band. Where the assessor cannot see something, such as insulation inside a wall, the model assumes based on the age of the building. This is the single biggest cause of people feeling their EPC is "wrong". The assessor did not guess badly. The software defaulted to what is typical for a house from that era, because there was no proof otherwise.

How is the EPC rating calculated (A to G)?

The certificate gives you an energy efficiency score from 1 to 100 or more, grouped into bands. The standard bands are:

The certificate also shows an Environmental Impact (CO2) rating, an estimated annual heating and hot-water cost, and a list of recommended improvements with indicative costs and savings. Those running-cost figures are modelled on standardised assumptions about how a typical household behaves, not on your actual bills. Treat them as a comparison tool between houses, not as a forecast of your gas bill.

Is there a minimum EPC rating to sell a house?

No. You can legally sell an F or G rated property. There is no regulation that stops a sale because of a low band, and buyers can purchase it with cash or a mortgage. The confusion comes from the rental sector: landlords currently cannot grant a new tenancy on a property rated below E unless they have a valid exemption, and a move to a minimum of C by 2030 has been proposed. If you are a landlord weighing up whether to upgrade or exit, read our dedicated guide on EPC C by 2030: should landlords sell or upgrade.

Where a low rating does bite is in the market. A poor band can make your property harder to mortgage if the buyer's lender takes a view on retrofit costs, and it gives a buyer ammunition to negotiate. That is a commercial problem rather than a legal one, and it is why the next sections matter.

Which properties are exempt from needing an EPC?

Exemptions are narrower than people hope. Broadly, an EPC is not required for:

• certain listed or protected buildings where meeting energy requirements would unacceptably change the character or appearance (listing alone does not automatically exempt you; it depends on whether compliance would cause that unacceptable change),
• stand-alone buildings under 50 square metres of useful floor area,
• buildings due for demolition where the seller or landlord has the right consents and the buyer intends to demolish,
• certain temporary buildings and places of worship.

If you think you fall into one, get written confirmation, perhaps from the conservation officer or your solicitor, rather than assuming. Our guide to selling a listed building explains how this plays out in practice. Many owners of listed homes still have an EPC done because buyers expect one and it costs very little.

Does the EPC rating affect your house price?

It can, but it is rarely the loudest voice in a price negotiation. Location, condition, size and the state of the kitchen and bathroom all outrank it for most buyers. I would not tell you a one-band improvement adds a fixed percentage, and anyone quoting you a precise figure is selling you something. There is research on the subject, but it varies by region and market and I will not present a headline number as if it were a rule.

What I can say is how the rating tends to show up in real sales:

• A weak rating hands buyers a handy line: "It will cost us a fortune to bring this up to scratch." That can turn into a price reduction request, especially if the survey also flags damp, an ageing boiler or single glazing.
• A strong rating is a mild selling point, particularly with buyers who are budgeting for energy bills and with lenders offering green mortgage products.
• For investor buyers, the band matters directly because they need to meet the letting standard. A property that is an E or better needs no work to let; an F or G needs spend before the first tenancy.

Should you upgrade your home before selling to improve the EPC?

Usually not extensively, and this is where I will give you a firm opinion. Do the cheap, quick, visible things. Do not launch into a retrofit programme purely for the band, because you will rarely get that money back in a sale price.

The reasoning is simple. A buyer will price what they see and can afford to fix. If you put £8,000 into a heat pump to lift an EPC from D to C and the buyer values it at £3,000, you have made a loss. If you instead spent £150 on LEDs and a cylinder jacket and had the loft topped up, you may have shifted a few points for almost nothing. Compare that to what a buyer would do themselves with the free advice at the bottom of the certificate.

There are exceptions. If you are selling a property where the EPC is poor and the buyer pool will mostly be mortgaged owner-occupiers, a single targeted fix can help the survey go smoothly. If you have recently installed a heat pump, our guide to selling a house with a heat pump explains how to present it, and if your solar panels are leased rather than owned you must read leased solar panels before you list.

Can you dispute an EPC rating you think is wrong?

Yes, and it is worth knowing how, because errors happen. The process runs through the assessor and their accreditation scheme, not through the property portals or the agent.

1. Check the data first. Read the "property summary" page of the certificate. Is the floor area right? Does it say your walls have no insulation when you know they are filled? Does it list single glazing when yours is double?
2. Contact the assessor in writing. Send evidence: installation invoices, guarantees, FENSA or similar certificates, dated photographs of insulation, boiler paperwork.
3. Ask for a reassessment. A competent assessor will correct a genuine error and relodge the certificate.
4. Escalate if needed. If the assessor refuses or does not respond, complain to the accreditation scheme they belong to. The scheme's details are on the certificate.

What you cannot do is argue the model's assumptions. If the assessor could not verify your cavity wall insulation and applied the default for a 1960s house, the certificate is "correct" until you produce proof. This is why I tell every seller to dig out the paperwork before the assessor arrives, not after.

What should you have ready for the assessor's visit?

A short, specific list saves arguments later:

• Boiler make, model and age (a photo of the data plate works).
• Any invoices or certificates for insulation, glazing, solar, heat pumps or new heating.
• Access to the loft, with the hatch clear.
• Access to the cylinder cupboard, meter cupboard and every room.
• Details of any extension, including the date it was built and whether it has building regulations sign-off.

On that last point, the EPC may sit alongside other paperwork a buyer's solicitor will chase. Our checklist on what documents you need to sell a house shows where the EPC fits in the wider pack, and the TA6 property information form is where you will describe those improvements formally.

Do cash house buyers care about your EPC?

They care less about the band than a mortgaged buyer does, because they are not waiting on a lender's retrofit assumptions. But the legal duty does not disappear just because the buyer is paying cash. You are still marketing a dwelling for sale, and a conveyancer acting for a company or investor will still expect the certificate on file.

If you are comparing quick-sale routes, the more useful point is this: a poor EPC is one of the reasons some conventional sales fall through and one of the reasons a house gets a lower offer on the open market. A cash buyer will price the whole condition of the property, including energy costs, into a single offer and will not ask you to go and fix anything first. If you want to see how that compares, the cash house buyers page and our wider sell house fast hub explain how those offers are built, and best house buying companies shows who to approach. Always compare more than one offer. A quick sale is not automatically a fair one.

What if your home has an F or G rating?

You can still sell it, and plenty of F and G properties change hands every week. They tend to be older, solid-walled, hard-to-heat houses, often in need of general updating as well. The market will price that in. Your options usually look like this:

For problem properties more generally, our hub on how to sell an unsellable house goes through the full list of routes. And if you want to know where your starting figure sits before you decide, try the how much is my house worth tool, then compare that to any quick-sale offer.

What about EPCs when selling a leasehold flat or a shared building?

Flats need an EPC just as houses do, and the assessor will base it on your flat alone, not the whole block. That has a few consequences:

• Communal heating and heat networks can complicate the assessment. If you are on a district system, read our guide to selling a flat on a heat network.
• A mid-floor flat with neighbours above and below often scores better than a house with the same insulation, simply because it loses less heat.
• The freeholder usually controls the roof, the walls and the windows, so you often cannot fix the things that drag the score down. Flag that honestly rather than promising buyers improvements you do not control.

What if you are selling an inherited property or a tenanted one?

Executors and personal representatives selling a probate property still need the EPC before marketing. Often the house has been empty for months, so book the assessor early and make sure there is power and access. It is a small cost that the estate pays, and it avoids a hold-up once a buyer is found. If you are in that position, our sell inherited property page walks through the process from valuation to completion.

If the house has a tenant, you still need an EPC, and you will need to arrange access with proper notice. A landlord selling a let property may already have a valid certificate because they needed one to rent it out, so check the register before ordering a second. Selling with the tenants in place is its own subject; see sell a tenanted property.

What are the new-style EPCs, and have the reforms started?

This is the question I get asked most at the moment, so here is where things stand. The government has been planning a major overhaul of how domestic EPCs work. Instead of one headline A to G score, the new certificate is designed around four separate metrics:

• Fabric performance: how well the building envelope holds heat.
• Heating system performance: how efficient and clean the heating is.
• Smart readiness: whether the home can use smart controls and respond to demand.
• Energy cost: an estimated annual running cost.

The calculation behind them is built on the Home Energy Model, which replaces the older methodology. The launch was originally pencilled in for October 2026. In its update of 9 March 2026, the government said it had decided to move the launch of the reforms for residential EPCs to the second half of 2027, with a new date and shared implementation plan to be agreed with industry and the devolved administrations. Law firm Reed Smith also notes that it is unclear whether the delay affects the timing of the higher residential minimum standards for landlords.

Common EPC mistakes sellers make

A few I see repeatedly, with my honest take:

• Waiting until there is a buyer. The agent cannot market properly without it and you create a delay you did not need. Book it the same week you pick your agent.
• Paying for a new one when a valid one exists. Search the register first. It takes two minutes.
• Not having evidence. If the cavity was filled in 2014, the paperwork is the difference between a defaulted assumption and a correct rating.
• Believing the running costs are real. They are modelled, not measured. Buyers who fixate on them are misreading the document.
• Over-investing in upgrades. We covered this above. Cheap wins yes, retrofit programmes no.
• Mixing up selling and letting rules. The E minimum is a lettings rule. It does not stop you selling.
• Letting the agent choose the assessor and mark it up. You are allowed to arrange your own.

How do you get an EPC, step by step?

1. Search the national register by postcode to see whether a valid certificate already exists for your address.
2. If none exists or it has expired, choose an accredited domestic energy assessor. Get two or three quotes.
3. Gather your evidence (insulation certificates, boiler details, glazing guarantees) and clear access to the loft and cylinder.
4. Book the visit and be present, or let the assessor in with a key if you are not.
5. Check the draft details when it arrives. Confirm the floor area, wall type, glazing and heating are correct.
6. Send it to your agent and solicitor, and make sure the rating appears in the listing.
7. Keep a copy. You will need it again if the first sale falls through and you re-list within the ten years.

EPC questions homeowners also ask

Who pays for the EPC when you sell?

The seller. The buyer receives it free of charge. If the sale falls through, the certificate remains yours to reuse for the next buyer within its ten-year life.

Can an estate agent produce the EPC?

Not themselves, unless they employ an accredited assessor. An agent can arrange for one, but the assessor must be accredited and the certificate lodged on the national register. You remain free to book your own.

Does a new boiler or double glazing change the EPC automatically?

No. The certificate only changes when a new assessment is carried out and lodged. Until then the old data stands, which is why paperwork and a reassessment matter after real improvements.

What is the difference between an EPC and a Home Report?

A Home Report is the Scottish seller's pack. It includes a single survey, a valuation and an EPC. In England, Wales and Northern Ireland, the EPC is a standalone requirement and the buyer organises their own survey.

Is an EPC the same as a survey?

No. An EPC measures energy efficiency from a visual assessment. It does not check structure, damp, drains or the roof. Our guide on what happens if a house survey finds problems shows what a proper survey picks up that an EPC never will.

Is the EPC part of what you must disclose to buyers?

It is part of it, but only one part. The EPC covers energy performance. Sellers also have wider duties around material information that affect a buyer's decision, from flood risk to disputes to building works. If you want the full picture, read material information when selling a house alongside this guide, and keep the terminology straight with our property jargon explained page.

Pulling it together: what I would actually do

If I were selling an ordinary house tomorrow, this is the order I would work in. Search the register for an existing EPC before I did anything else. If there was none, I would book a local accredited assessor the same day and have the paperwork ready for them. I would swap the last of the old bulbs, check the loft insulation and sort the cylinder jacket if it was missing, because those take an afternoon and cost almost nothing. I would not touch a retrofit project. I would put the certificate into the pack my agent and solicitor receive, and I would get on with the actual job of pricing and presenting the house. If the rating turned out poor and the house needed wider work, I would get an honest idea of what it could fetch both ways: on the open market, and from a quick-sale buyer.

For wider preparation, our how to get your house ready to sell guide, and the full library at our guides hub, cover everything around the EPC. If you are weighing a quick sale and want to see what real offers look like, compare offers for your home with no obligation. It costs nothing to see the numbers, and you decide whether any of them is worth taking.
