How Much Does an EPC Cost in 2026?
An Energy Performance Certificate costs £55 to £150 in 2026, and £65 to £95 for a typical two or three bedroom house outside London. The assessor is on site for under an hour, the certificate lasts ten years, and you must have commissioned one before a home is marketed for sale or rent. Before you pay for anything, check the national register: most homes in England and Wales already have a valid certificate you can download free. This guide gives the price by property size and region, explains what the assessor can and cannot count, and shows the cheap changes that move the score before the visit.

Assessors price by how long the survey takes, which tracks the number of rooms, heated extensions and heating zones. A one-bedroom flat with a combi boiler is half an hour; a period house with three extensions and two heating systems can take an hour and a half. These are the September 2026 ranges outside London and the South East.
| Property | Time on site | EPC cost |
|---|---|---|
| Studio or 1-bed flat | About 30 minutes | £55 to £70 |
| 2-bed flat or maisonette | 30 to 40 minutes | £60 to £80 |
| 2 or 3-bed terrace or semi | 40 to 50 minutes | £65 to £95 |
| 4-bed house | 50 to 60 minutes | £80 to £115 |
| 5-bed house | 60 to 75 minutes | £95 to £130 |
| Large, rural or period house with extensions | 60 to 90 minutes | £110 to £150 |
Prices include VAT and lodging the certificate on the register. Booking two properties on the same street on the same day usually saves £10 to £20 on the second.
The spread inside each row is mostly overhead. A sole trader assessor working locally sits at the bottom of the range; a national panel that books the job and subcontracts it sits at the top. The certificate is identical either way, because the software and the method are set by government, not by the assessor.
EPC prices by region
| Region | Against the base price | 3-bed house |
|---|---|---|
| London | Plus 20 to 30 percent | £80 to £120 |
| South East and East of England | Plus 10 percent | £72 to £105 |
| Midlands, North West, Yorkshire, South West | Base | £65 to £95 |
| North East | Minus 5 percent | £62 to £90 |
| Wales | Base | £65 to £95 |
| Rural areas more than 30 minutes from a town | Plus £15 to £30 travel | £80 to £125 |
Scotland runs a separate system: certificates there are produced under Scottish regulations and lodged on the Scottish EPC register, and prices sit close to the North of England. The rules on this page are for England and Wales.
Check the free register first
Most homes already have a certificate. Every EPC produced since 2008 is public and free to download from the government register at gov.uk/find-energy-certificate, searchable by postcode. If yours was lodged less than ten years ago it is still valid, and you do not need to buy another to sell or let, or to apply for most grants.
Two things are worth knowing about an old certificate. The score reflects the home as it was on the day of the visit, so work you have done since (a new boiler, a filled cavity, 270 mm in the loft) is not on it and will not help you until the property is reassessed. And an old certificate was produced under an older version of the method, so a reassessment today can move the number even if nothing physical has changed. Our guide to how EPC points are calculated explains what the software actually rewards, and the EPC calculator estimates where your home would land now.
What the assessor does on the visit
A domestic energy assessor accredited under a government-approved scheme carries out a survey using RdSAP, the reduced data version of the Standard Assessment Procedure. They measure the heated floor area room by room, note the construction of the walls and roof, count and measure windows, record the boiler or heat pump and its controls, check the loft and the hot water cylinder, and photograph the evidence. The assessment is not an inspection of condition: damp, a failing roof and a cracked flue are outside its scope, which is why an EPC is not a survey.
Since 15 June 2025 the method has been RdSAP 10, and the important change for a homeowner is that it is evidence based. Where the assessor can see or be shown something, they enter it. Where they cannot, the software assumes a default from the age of the building, and the default is usually worse than the reality. A filled cavity with no paperwork and no visible drill pattern is scored as unfilled. A boiler with no manual and an unreadable data plate is scored at a default efficiency. Fifteen minutes finding the paperwork is worth more than anything else you can do on the day.
The certificate is lodged on the register within about 24 to 72 hours and comes with a recommendations report listing measures, indicative costs and the points each would add. That report is the document to keep: it is what grant schemes and, for rentals, the minimum standard rules work from.
When you need an EPC, and the £200 penalty
| Situation | Do you need one? | Rule |
|---|---|---|
| Putting a home on the market to sell | Yes, commissioned before marketing starts | Regulation 6 |
| Advertising a home to let | Yes, and the rating must appear in the advert | Regulations 6 and 11 |
| New build on completion | Yes, the builder provides it | Regulation 29 |
| Renewing a tenancy with the same tenant | No, that is not marketing | Regulation 6 |
| Remortgaging or improving your own home | No legal requirement, but lenders offering green rates ask for one | Lender terms |
| Applying for a grant such as ECO4 or the Boiler Upgrade Scheme | Usually yes, as evidence of the starting rating | Scheme rules |

The seller or landlord is responsible, not the buyer or tenant. You must use all reasonable efforts to have the certificate within seven days of marketing, with a further 21 days allowed if the assessment has been commissioned, and a copy must be given free to anyone who receives written particulars. Enforcement sits with trading standards, and the penalty charge for a dwelling is £200 per breach. Letting a home rated F or G without a registered exemption is a separate and much more expensive matter: see our EPC guide for landlords, because from 1 October 2030 rented homes have to reach the new band C standard.
Which homes are exempt
- Listed buildings, but only where meeting the minimum energy performance requirements would unacceptably alter their character or appearance. Being listed is not an automatic exemption, and agents who assume it is have been fined.
- Places of worship and temporary buildings in use for two years or less.
- Standalone buildings under 50 square metres of useful floor area.
- Homes due for demolition where the seller holds the relevant planning and conservation consents.
- Holiday lets occupied for less than four months a year, or let under a licence to occupy, though the rules here are narrow and worth checking before relying on them.
How to pay less, and what a free EPC really is
- Check the register before you book. A valid certificate you already have costs nothing, and this is the single most common way people waste £80.
- Book a local assessor directly. National panels and comparison sites add £10 to £30 for the same certificate. The GOV.UK assessor finder lists accredited assessors by postcode.
- Take the estate agent's free EPC with your eyes open. It is real and it is genuinely free, but it is paid for out of your commission and it is commissioned by the agent, so the certificate belongs to the marketing and you may not get the recommendations report unless you ask. If you are selling anyway, take it. If you are only assessing your own home, buy your own.
- Bundle the visit. Assessors discount a second property in the same trip, which suits anyone selling one home and buying another.
- Do not pay for a rush. Same-day and next-day slots carry a £20 to £40 premium. Standard booking is two to five working days.
- Do not skip the reassessment after improvement work. If you have insulated or replaced the heating, the old certificate understates your home. A £75 reassessment that moves you from band E to band C is the cheapest part of the whole project.
Lifting the score before the assessor arrives
None of this is gaming the system. RdSAP 10 scores what can be evidenced, so the job is to make sure the assessor can evidence what is already there, then fix the handful of cheap things that genuinely count.
| Before the visit | Cost | Effect on the rating |
|---|---|---|
| Find the cavity wall insulation guarantee or CIGA certificate | £0 | Large. An unevidenced cavity is scored as unfilled |
| Find the boiler manual, or clean the data plate so the model is readable | £0 | Moderate. Unknown boilers get a default efficiency |
| Clear the loft hatch and expose the insulation so it can be measured | £0 | Moderate. Depth is measured, not assumed, when visible |
| Find window certificates (FENSA or CERTASS) for replacement glazing | £0 | Moderate, particularly on older double glazing |
| Fit low energy bulbs throughout | £15 to £40 | Small but certain. Percentage of fixed low energy lighting is counted directly |
| Top the loft up to 270 mm | £300 to £600 | Up to 8 points. See is loft insulation worth it |
| Fit a room thermostat and thermostatic radiator valves if missing | £150 to £400 | 2 to 3 points, and it cuts bills immediately |
| Insulate the hot water cylinder to 80 mm | £20 to £40 | 1 to 2 points on homes with a cylinder |
Point values are typical RdSAP gains and vary with the property. Our EPC calculator ranks every measure by points per pound for your own home.
For the bigger moves, the order that usually pays is insulation first, then controls, then the heating system. Cavity wall insulation is the largest single jump available to most post-1930 houses, solid wall insulation is the largest for older ones, and a heat pump adds 10 to 15 points while qualifying for the £7,500 grant. Check the grant eligibility checker before paying for any of it, and see how to improve your EPC rating for the full sequence.
The certificate is being redesigned
The government consulted on reforming the Energy Performance of Buildings regime and published a partial response on 21 January 2026, confirming that new domestic certificates will carry four headline metrics rather than one: energy cost, fabric performance, heating system and smart readiness. They will be calculated with the Home Energy Model, which replaces the Standard Assessment Procedure. In March 2026 the launch moved from October 2026 to the second half of 2027, and no firm date has been published since.
Two questions are still open, and both matter if you are deciding whether to buy a certificate now: how long new certificates will be valid, with options consulted on from under two years to keeping the current ten, and whether an existing certificate has to be replaced early. Until the government answers, a certificate lodged today runs for ten years on the current rules. For rented homes there is one date already fixed: a home rated C on the existing rating on a certificate issued before 1 October 2029 counts as compliant with the 2030 standard until that certificate expires.
Frequently asked questions
How much does an EPC cost in 2026?
£55 to £150 depending on the size of the property, and £65 to £95 for a typical two or three bedroom house outside London. London adds 20 to 30 percent and rural travel adds £15 to £30. The price includes the survey and lodging the certificate on the register.
How long does an EPC last?
Ten years from the date it is lodged. You can sell or let on a certificate at any point in those ten years, and you do not have to renew it early unless you want the improvements you have made since to be reflected in the rating.
Can I get an EPC for free?
You can download a copy of any existing certificate free from the government register, and many estate agents include a new one when you instruct them to sell. A fresh certificate commissioned on your own account is not free, because an accredited assessor has to visit.
How long does an EPC assessment take?
Thirty minutes for a small flat and up to 90 minutes for a large period house. The certificate appears on the register within about 24 to 72 hours of the visit.
What is the penalty for not having an EPC?
A £200 penalty charge per dwelling, issued by trading standards, for marketing a home without having commissioned a certificate. Letting a home rated F or G without a registered exemption carries penalties of up to £5,000 per property.
Does a new boiler improve an EPC rating?
Yes, typically by 5 to 8 points if you are replacing a boiler more than 15 years old, which is often enough to move up a band. A heat pump adds 10 to 15. Neither shows on the certificate until the property is reassessed, which is the £75 most people forget to spend.
