A domestic EPC in 2026 typically costs from around £35 for a studio or one-bedroom flat, rising with the number of bedrooms and floor area, with most three and four-bedroom houses falling between £60 and £100. Commercial EPCs start from around £150 and scale with floor area and the complexity of the building's services. Prices vary by assessor, location and how quickly you need the certificate, and London postcodes with parking restrictions or congestion charging can carry a modest travel supplement.
An EPC's price is not arbitrary — it reflects the time an assessor spends on site and the complexity of translating what they find into the RdSAP or SBEM calculation. A one-bedroom flat with a single heating zone and no loft to inspect takes a fraction of the time a five-bedroom period house with an extension, multiple heating zones and a loft conversion does. Number of bedrooms and total floor area are the two biggest drivers, followed by property type (flats are usually simpler than houses because there's less external fabric to record), and whether the building has unusual features such as multiple extensions, mixed construction periods, or renewable technology that needs recording accurately.

Typical domestic EPC prices
Prices below reflect a standard booking with normal turnaround across Greater London and the Home Counties. They will vary by assessor and can move for larger properties, HMOs surveyed room by room, or addresses that require congestion charge or ULEZ travel. Always confirm whether a quote includes VAT and lodgement on the Register, since some cut-price quotes charge separately for the certificate to actually be registered.

The buildings behind this advice
Commercial EPC pricing
Commercial EPCs use a different methodology (SBEM rather than RdSAP) and are priced accordingly, because the assessor has to record HVAC systems, zoning, lighting controls and building services in far more detail than a domestic survey requires. A small single-unit shop or office is the cheapest commercial category; large or multi-let buildings, buildings with complex mechanical ventilation, or those needing an on-construction assessment cost significantly more. Always ask whether the quote is for the whole building or a single demise within it, since commercial EPCs are sometimes required per unit rather than per building.
Small retail unit or single office: from £150
Larger office floor or multi-unit retail parade: £200–£400
Warehouse or industrial unit: variable, depends on services and zoning
Complex mixed-use or serviced buildings: quoted individually
What's usually included in the price
A reputable quote should be all-in: the site visit, the assessor's RdSAP or SBEM calculation, the certificate itself, and lodgement on the national EPC Register, without which the certificate has no legal standing. It should also include the recommendations report that accompanies every certificate. What it will not include, unless separately agreed, is any retrofit advice consultancy, follow-up re-assessment after improvement works, or expedited same-day service, which some assessors price as an add-on.
What to confirm before booking
Is lodgement on the official EPC Register included?A certificate that isn't lodged has no legal validity
Is the assessor accredited?Check they're registered with an approved accreditation scheme
Is VAT included in the quoted price?
Is there an extra charge for same-day or weekend bookings?
Does the price cover the whole property, including any annexe or outbuilding?
Why the cheapest quote isn't always the best deal
The domestic energy assessment market has no fixed price list, which means quotes for what looks like the same job can vary by 50% or more. The lowest few quotes online are sometimes from unaccredited operators, from assessors who intend to charge extra for lodgement, or from businesses that subcontract the job to whoever is cheapest and nearest on the day, with no consistency in the assessor's local knowledge or availability if something needs re-checking. A certificate that isn't correctly lodged, or contains errors that need correcting after a solicitor queries it, ends up costing more in delay than the saving on the initial quote.
Check the assessor's accreditation number is valid and current
Ask whether the same assessor attends and lodges the certificate themselves
Read recent reviews specific to EPC work, not just general property services
Confirm what happens if the property doesn't match the quote (extra rooms, loft conversion, etc.)
London-specific cost factors
Assessors working across Greater London sometimes add a modest travel supplement for addresses inside the congestion charge zone or where ULEZ compliance and parking restrictions add time and cost to the visit. This isn't universal, and a local assessor based centrally within London — as opposed to one travelling in from outside the M25 — will usually avoid or minimise it. If you're comparing quotes from assessors based in different parts of the country, ask specifically whether congestion charge, ULEZ or parking costs are already factored into the price you've been given.

Getting a firm, accurate quote
The fastest way to a reliable price is to give the assessor the bedroom count, approximate floor area, property type and postcode upfront, rather than requesting a generic 'EPC price' that gets quoted against an assumed average property. For landlords with multiple properties or agents instructing EPCs regularly, ask about a portfolio rate — most assessors will offer a lower per-unit price once volume and repeat business are on the table.
