EPC Cost London 2026: How Much Does an EPC Certificate Really Cost?

If you’re selling, letting or remortgaging a property, one of the first questions is always the same: what’s the EPC cost in London? The honest answer is that it depends on the size of the property and how quickly you need it — but for most homes across South and South West London, you’re looking at somewhere between £45 and £90 for a standard domestic assessment.

This guide breaks down exactly what drives the price, what a fair market rate looks like in 2026, and how to avoid overpaying for something that’s a legal requirement for almost every seller and landlord in England and Wales.

Average EPC Prices in London (2026)

Pricing for a Domestic Energy Assessment (the type almost every homeowner and landlord needs) is largely driven by the number of habitable rooms an assessor has to survey, since more rooms mean more measurements, photos and time on site.

These are the current rates for EPC London Ltd’s certified assessments, and they’re broadly in line with what you should expect to pay anywhere in Greater London for a straightforward domestic survey. If a quote comes in well below this for a comparable property, it’s worth asking whether the assessor is actually a member of an accredited scheme — an EPC produced by an unaccredited assessor isn’t valid and won’t be accepted by the official register.

What Actually Affects the Cost of an EPC?

Property size and layout. The more rooms, extensions and floors an assessor has to measure, the longer the visit takes. A one-bed flat is a quick job; a converted period house with an extension and loft conversion takes considerably longer to survey accurately.

How quickly you need it. A standard booking is usually the most cost-effective option. If you need a certificate the same day or next day — common when a sale is close to exchange or a tenancy is about to start — you may pay a modest premium for priority scheduling. See our guide on getting an EPC quickly if time is tight.

Access on the day. Assessors need to see every habitable room, the loft, the boiler and any insulation evidence. If access is difficult (tenanted property with an awkward viewing window, keys held by a third party, etc.) it can add time and occasionally cost.

Bundled services. If you’re also booking floor plans or property photography for the same listing, doing them in a single visit is usually cheaper overall than booking each separately, since the assessor is only travelling to the property once.

Is It Worth Paying More for a Faster or “Premium” EPC?

Not really — an EPC is an EPC. Every certificate, regardless of price, has to be produced by a Domestic Energy Assessor accredited under the same government scheme, follow the same RdSAP methodology, and get lodged on the same national register. What you’re really paying extra for when you see a higher price is usually speed, availability, or a bundled service — not a “better” certificate.

What’s worth checking before you book:

• The assessor’s accreditation number, which should be quotable on request
• Whether the price includes VAT and lodgement on the register
• How quickly you’ll actually receive the finished certificate
• Whether the same visit can cover photography or floor plans if you need them

Do You Legally Need an EPC?

Yes, in almost every case. Under UK regulations, you must have a valid EPC when you’re selling a property, renting it out, or building a new one, and it needs to be available to buyers or tenants before you market the property. Certificates are valid for 10 years, so if you’ve owned or let a property for a while, it’s worth checking the register to see whether you already have one before booking a new assessment.

If you’re a landlord, the rules are getting stricter rather than looser — our guide to the EPC C rating 2030 deadline explains what’s changing and why it pays to get ahead of it now rather than scrambling closer to the deadline.

How to Book an EPC in London

1. Check whether the property already has a valid certificate on the Find an Energy Certificate service — search by postcode, free of charge.
2. If you need a new one, book an EPC assessment online and pick a time that suits — most appointments across South and South West London are available within 24 hours.
3. Make sure the assessor can access every room, the loft and the boiler on the day, so the visit doesn’t need rescheduling.
4. Add on floor plans or photography at the same visit if you’re preparing a listing — it saves a second trip and usually costs less than booking separately.
5. Your certificate is lodged on the national register and valid for 10 years from the date of issue.
