As the UK moves into 2026, Energy Performance Certificates (EPCs) are becoming more than just a legal formality. Mortgage lenders, buyers, tenants and regulators are paying closer attention to EPC ratings — and many property owners are unsure whether their existing certificate is still valid.
How Long Does an EPC Last in the UK?
In England, Wales and Northern Ireland, an EPC is valid for 10 years from the date it is lodged. Once it expires, it can no longer be used for:
- Selling a property
- Letting a property
- Marketing a property online or with an agent
If your EPC was issued in 2016, it will expire at some point in 2026 — and many homeowners don’t realise this until a sale or tenancy is already underway.
Do I Need a New EPC in 2026?
You will need a new EPC in 2026 if:
- Your existing EPC has expired
- You are selling your home
- You are renting out a property or renewing a tenancy
- You are switching mortgage products and the lender requests an updated EPC
If none of the above apply and your EPC is still within its 10-year validity, you are not legally required to replace it — but that doesn’t always mean you shouldn’t.
Why Updating an EPC Early Can Be a Smart Move
Even if your EPC is still valid, many homeowners choose to update it in 2026 because:
- They’ve installed a new boiler
- They’ve upgraded insulation or glazing
- They’ve added extensions or converted lofts
- The original EPC no longer reflects the property accurately
An outdated EPC can undervalue your home’s efficiency, which may reduce buyer confidence or trigger further questions during conveyancing.
EPC Ratings and Landlords in 2026
Landlords should be especially careful in 2026. Current rules require most rented properties to achieve a minimum E rating, but future proposals continue to focus on improving energy efficiency across the private rented sector.
While not all proposed changes are yet law, many landlords are already upgrading properties proactively to avoid being caught out later.
Can I Use an Old EPC If I’ve Made Improvements?
No. EPCs do not update automatically. If you’ve improved your property since the last assessment, the EPC will not reflect this unless a new one is carried out.
This means:
- You won’t benefit from a higher rating
- Buyers and tenants won’t see your improvements
- You may miss out on better offers or faster transactions
How Long Does a New EPC Take?
A typical EPC assessment takes 30–60 minutes depending on the property. The assessor will review:
- Heating systems
- Insulation levels
- Wall and roof construction
- Glazing type
- Hot water systems
Most EPCs are lodged and available digitally on the same day.
