How Long are SAP & EPC Certificates Valid For?

If you’re looking to buy, sell, or rent out a property, you may have questions about SAP and EPC certificates, and how long they’re valid for. In this article, we discuss the validity of SAP, RdSAP, and EPC certificates, as well as a few other things you may need to know.

So, how long are SAP & EPC certificates valid for? SAP, RdSAP, and EPC certificates are all valid for 10 years under normal circumstances. You must ensure that your EPC certificate is still valid before attempting to sell or rent out your property, and that your EPC rating is E or above if you wish to rent out your property.

Read on to learn more about how long EPC certificates are valid for.

How Long are SAP Calculations Valid For?

Both SAP EPC calculations and RdSAP calculations are valid for 10 years. However, for new builds, new dwellings created from a change of use, a full SAP EPC certificate must be lodged – an RdSAP certificate is not sufficient, and can only be created for existing dwellings.

As such, a full SAP EPC certificate will be required once the build is complete. RdSAP certificates should only be used if a full SAP certificate has previously been lodged on the National Registers.

If you wish to sell your home or rent it out, you must ensure that your SAP EPC certificate is still valid, and undergo assessment if your certificate has expired. This must be done before the property is marketed.

How Long is an EPC Certificate Valid For?

A full EPC certificate is valid for 10 years. Like with SAP EPC, you must have a valid EPC certificate before you can sell or rent out your property, and this must be produced to the sales or letting agent before the property can be listed.

How Long is an EPC Valid For When Letting?

The validity of an EPC certificate is the same for letting as for selling; 10 years. The certificate can be used across multiple tenancies on the same property, as long as the EPC rating is E or above (this changes to a C rating or above in 2025).

How Do I Know if My EPC is Valid?

If you’re a homeowner looking to sell your property, you should have an EPC certificate that details the issuing date and expiration date. However, if you don’t have a certificate, can’t find it, or if you are looking to buy or rent a property, you can check the EPC rating and expiration date of a property on the National Register (England & Wales, Scotland).

This search provides the A-F EPC rating, the SAP score (0-100) of a property, and if there is potential for the EPC rating to improve or decline. It also provides suggestions on how each property can improve their EPC rating.

What is the Fine for Not Having an EPC?

As soon as you declare intent to sell or rent your property, it is your responsibility to ensure that your EPC certificate is valid, and that it is compliant with various regulations. Your EPC certificate must be made available to estate agents and prospective buyers free of charge.

Estate agents will not market your property if you cannot produce a valid EPC certificate, unless you can prove that you have commissioned an EPC assessment before they begin marketing your property. From here, you have 28 days to produce this commissioned certificate.

If you cannot produce an EPC certificate after 28 days, and your property is still being advertised, Trading Standards Officers may choose to serve a penalty notice.

Penalties are given as such:

  • Domestic properties – £200
  • Non-domestic properties – Sum equivalent to 12.5% of the rateable value of the building, subject to a minimum of £500 and a maximum of £5,000
  • Where this cannot be applied, a default penalty of £750 is issued
