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 | Verified |
|---|---|---|---|
| GOV.UK EPC Register (Find an Energy Certificate) | Free | Free EPC lookup by postcode (England, Wales & NI official register) | 2026-08-02 |
| Elmhurst Energy | £6.89 | £6.89 +VAT per EPC lodgement (entry price, excludes UK EPC Register fee) | 2026-08-02 |
| Quidos | £5.60 | £5.60 +VAT per RdSAP lodgement on Bronze (no monthly fee; +£1.50 register fee, £2.60 Scotland) | 2026-08-02 |
Why prices rose in 2025-26
Three documented pressures, all pushing the same way:
- 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 went up. Elmhurst's assessor renewal rose from £95 +VAT to £125 +VAT from 1 August 2026, with the free-renewal threshold raised from 25 to 30 lodgements a year Elmhurst.
- Consolidation. Elmhurst's merger with Stroma Certification completed in May 2026, leaving one scheme handling more than half of UK lodgements, by its own account Elmhurst.
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.
