There is no official fixed price
The government does not set one national fee for a domestic EPC. Assessors and providers set their own prices, so a responsible cost guide should not present an unsupported nationwide “average” as a guarantee.
The amount quoted can vary with location, property size and complexity, access, travel, urgency and the provider's service model.
What the fee should cover
- A visit and data collection by an accredited domestic energy assessor.
- The calculation of the energy-efficiency and environmental-impact ratings.
- Lodgement of the certificate on the official register.
- The certificate and recommendation report.
Ask whether VAT, travel, urgent turnaround or a failed-access revisit could add to the price.
How to compare quotes
- Use the GOV.UK service to find an accredited assessor.
- Give each assessor the same property details.
- Ask for the total price including lodgement and VAT.
- Confirm turnaround and access requirements.
- Check the assessor and accreditation scheme rather than choosing on price alone.
Estate or letting agents may offer to arrange the certificate. You can compare that fee with a direct assessor quote.
Avoid two common mistakes
A very low quote is poor value if it excludes necessary charges or produces an unreliable assessment. An expensive package is not automatically better if you only need a standard domestic EPC.
An EPC is not a retrofit design survey. If you need detailed heat-loss calculations, moisture analysis or a whole-house retrofit plan, commission that work separately from an appropriately qualified person.
