- The method
How EPCs for existing homes are assessed
The government has updated the method used for EPCs on existing homes, which is now RdSAP 10. Here is what it means for you.
- RdSAP 10
The current method: RdSAP 10
RdSAP 10 collects more detail about the home than earlier versions, so the rating depends more on facts about the property and less on assumptions. If there is no evidence for an improvement, the assessment cannot take it into account, and the rating can come out lower.
More detail collected
We record more specific information, including the size and type of the glazing and the heating system, backed by evidence such as model numbers or manufacturer data where it is available.
Evidence for improvements
Improvements such as new insulation or new windows are only counted where there is evidence for them, so homeowners, landlords and agents should have the paperwork ready.
What this means for you
Have your documents ready before the visit: installation certificates, product details and receipts for improvements all help the EPC reflect the home accurately.
Why it matters
An EPC based on verified information gives a rating that reflects the home as it is now.
- Requirements
Who needs a domestic EPC
When the law asks for an EPC on a home
- Selling a property
Required when selling
You need an EPC to sell a home, and estate agents show its rating when they market the property.
- Letting a property
Required when letting
Landlords need a valid EPC to let a home, and a rented home must currently have a rating of E or above unless it is exempt. The government plans C by 1 October 2030, which is not yet law.
- New builds
Required for new homes
A newly built home needs an EPC, and the certificate is lodged on the national register.
What an EPC tells you
An EPC grades a home from A, the most efficient, to G, the least efficient, and includes recommendations for improving it.
How long an EPC lasts
A domestic EPC is valid for 10 years. If you make significant energy improvements before then, a new assessment will show them in the rating.
