How Long Does an EPC
Certificate Last?
An EPC lasts 10 years from the date of issue. Sellers plus landlords can use the same EPC across multiple sales or tenancies during that period. After 10 years a new assessment is required. Some owners renew earlier when significant improvements have been made.
An EPC certificate is valid for 10 years from the date it was issued. During those 10 years it can be reused for any sale or tenancy of that property. The EPC stays on the official EPC Register at epcregister.com regardless of who owns or rents the property. After 10 years the EPC expires plus a new assessment is required if the property is sold, rented or has any other EPC requirement. Owners can choose to commission a new EPC earlier than 10 years (for example after major energy improvements) to reflect the current state plus typically achieve a higher rating. Government plans confirmed in January 2026 keep the 10-year validity period under the new HEM:EPC system from October 2029.
The figures that matter
Validity period
From the date of EPC issue. Same period applies across England plus Wales.
Reusable
The same EPC can cover multiple sales plus tenancies during its 10-year life.
EPC Register
Anyone can search the EPC Register at epcregister.com by postcode plus see current rating plus expiry.
Optional
Owners can commission a new EPC anytime to reflect improvements plus get a higher rating.
Four things to consider
10 years from issue date
Not from date of property purchase or tenancy. Always check the issue date on the EPC document itself.
Reusable across sales plus lets
If valid plus accurate, the same EPC covers multiple sales or rentals in 10-year window.
Some recent improvements may not show
Improvements like new boilers or insulation made after the EPC do not change the existing rating until renewal.
Renew early after major works
If you have done significant energy improvements, a new EPC can show the higher rating plus help future sale or let.
How EPC validity works in practice
The 10-year EPC validity period sits at the heart of how EPCs are used in UK property transactions. Understanding when EPCs expire plus when to renew matters for sellers, landlords plus buyers.
The 10-year rule. Under the Energy Performance of Buildings (England plus Wales) Regulations 2012, EPCs are valid for 10 years from the date of issue. The date appears at the top of the EPC document plus on the EPC Register listing. After 10 years the EPC expires automatically. There is no warning notice plus no extension. To continue using the property in any way that requires an EPC (sale, new tenancy, advertising), a new EPC must be commissioned.
What 10 years means in practice:
- EPC issued 1 March 2016 expires 1 March 2026. After this date, the property has no valid EPC.
- EPC issued 15 June 2020 expires 15 June 2030. Still valid for sales plus tenancies until that date.
- EPC issued before 2016 has already expired plus cannot be used.
Reusing the same EPC. Within the 10-year window, the same EPC can be used for:
- Multiple sales of the same property (if sold then resold).
- Multiple tenancies (each new tenancy can use the existing EPC).
- Refinancing or remortgaging.
- Building regulations applications.
- Any other purpose that requires an EPC.
There is no need to commission a new EPC for each sale or tenancy if the existing one is still valid.
When to renew an EPC early. Sometimes commissioning a new EPC before the 10 years are up makes sense:
- After significant energy improvements. New boiler, loft insulation, cavity wall insulation, double glazing or solar panels can all raise the rating significantly. A new EPC reflects the improvement plus helps any future sale or tenancy.
- Before selling. If your existing EPC is 7+ years old plus you have made improvements, a fresh EPC may show a higher rating that buyers plus mortgage lenders factor into their decision.
- Before letting. If your rental property is rated F or G, you must improve to E or higher. A new EPC after the improvements proves compliance with MEES Regulations 2015.
- If the original EPC contains errors. If the original assessor missed insulation or features, an early reassessment can correct the rating.
What happens at the end of 10 years. The EPC simply expires. There is no formal notification. The property's listing on the EPC Register shows the certificate as expired. Any sale, new tenancy or relevant transaction after that date requires a new EPC. The new EPC is a fresh assessment, not an extension of the old one. The new rating may be higher or lower depending on changes to the property plus the SAP/RdSAP methodology.
The new HEM:EPC system from 2029. The Home Energy Model methodology will replace SAP/RdSAP. The launch is scheduled for the second half of 2027. From 1 October 2029, all new EPCs will be issued using HEM:EPC. EPCs issued before that date under the current SAP/RdSAP methodology will remain valid for their full 10-year period. After 1 October 2029, all renewals plus new EPCs use HEM. The 10-year validity period continues under the new system.
Practical guidance for property owners:
- Note your EPC issue date plus expiry. Set a calendar reminder 12 months before expiry.
- Search the EPC Register at epcregister.com if you cannot find the document. The register holds all EPCs issued in England plus Wales.
- Consider early renewal if you have made improvements that would raise the rating.
- If your EPC is close to expiry plus you plan to sell or relet, commission a new one early to avoid sale delays.
- Keep paper plus digital copies of the EPC plus all improvement certificates.

How EPC validity plays out across 10 years
EPC issued
DEA carries out assessment. EPC issued plus lodged on register. 10-year validity begins from issue date.
Reusable for sales plus lets
EPC available for any sale, new tenancy or refinancing during this period. Free to anyone who searches.
Consider improvements
Major upgrades (boiler, insulation, glazing) can raise the rating. Early renewal worth considering.
Expiry
EPC expires automatically. New assessment needed for any future sale, tenancy or EPC requirement.
Four EPC validity points worth knowing
Validity is from issue date
Not purchase or tenancy date. Check the EPC document or register listing for the original issue date.
Same EPC covers multiple uses
Multiple sales, tenancies plus refinancing within the 10-year window can all use the same EPC.
Renew early after major upgrades
New boiler plus insulation can raise rating significantly. New EPC reflects this plus helps future sale or let.
Set calendar reminder 12 months before expiry
Avoids last-minute scramble for new assessment when selling or reletting.
