Straight answer first: there is no fixed fee. The government's own guidance says to get quotes from accredited assessors, who price for themselves GOV.UK. Any site quoting you a single national EPC price is rounding a market into a number. We publish only what we can verify, so this page shows the cost structure underneath every quote instead.
Why quotes vary
- Property size and type. More rooms, extensions and unusual construction mean longer surveys.
- Region. Assessor travel time and local competition move prices.
- Who books it. An estate or letting agent arranging "their" assessor typically adds margin over booking direct.
The verified floor under every quote
Assessors pay accreditation schemes per certificate they lodge, so scheme fees are the verifiable base of the market. Two of the largest schemes publish theirs:
| Provider | Published rate | Model |
|---|---|---|
| GOV.UK EPC Register (Find an Energy Certificate) | Freechecked 2026-10-19 | Free EPC lookup by postcode (England, Wales & NI official register) |
| Elmhurst Energy | £6.89checked 2026-10-19 | £6.89 +VAT per EPC lodgement (entry price, excludes UK EPC Register fee) |
| Quidos | £5.60checked 2026-10-19 | £5.60 +VAT per RdSAP lodgement on Bronze (no monthly fee; +£1.50 register fee, £2.60 Scotland) |
What pushes a quote up
Three documented pressures on the assessor side:
- RdSAP 10 lengthened surveys. Since 15 June 2025 assessors must measure every window, record ventilation detail and collect evidence rather than assume defaults, which means more time on site per job Elmhurst RdSAP 10.
- Scheme fees. On top of the per-certificate fee, Elmhurst charges assessors an annual renewal of £125 +VAT unless they lodged 30 or more EPCs the previous year Elmhurst, a fixed cost that weighs most on part-time assessors.
- Concentration. Elmhurst says its members lodge more than half of UK EPCs Elmhurst, so its fee schedule shapes much of the market.
How to pay £0
A certificate lodged by a previous owner or landlord may still be valid: EPCs last 10 years and stay with the property, not the person. Checking the register is free GOV.UK register, takes a postcode, and is the single most skipped step in the whole process. Do it before you book anyone.
