If you’re selling, renting, or managing property in London, understanding how long an Energy Performance Certificate (EPC) remains valid is essential. Many homeowners, landlords, estate agents, and property investors ask the same question: How long does an EPC last?
The simple answer is that an EPC is valid for 10 years from the date it is issued. However, there are several important situations where you may need a new certificate sooner, especially if you’ve made significant improvements to your property or are preparing it for sale or rental. According to UK government guidance, EPCs are required when selling, renting, or constructing a property and remain valid for ten years.

What Is an EPC?
An Energy Performance Certificate (EPC) measures the energy efficiency of a property. The certificate provides a rating from A (most efficient) to G (least efficient) and includes recommendations that could improve the property’s energy performance.
An EPC helps:
- Homeowners understand energy costs
- Buyers compare properties
- Landlords comply with regulations
- Tenants estimate running expenses
- Property investors identify improvement opportunities
Every certificate includes:
- Current energy rating
- Potential energy rating
- Estimated energy costs
- Carbon emissions data
- Recommended improvements
How Long Does an EPC Last in London?
In London, as in the rest of England and Wales, an EPC remains valid for 10 years from the assessment date. Once issued, it can be reused multiple times during that period for property sales or rental transactions.
For example:
| EPC Issue Date | Expiry Date |
|---|---|
| January 2026 | January 2036 |
| July 2025 | July 2035 |
| March 2024 | March 2034 |

Why Are EPCs Valid for 10 Years?
The UK government established the 10-year validity period because many property characteristics remain relatively stable over time. Features such as:
- Wall construction
- Roof insulation
- Window types
- Heating systems
- Property layout
often do not change dramatically within a decade.
However, significant upgrades can improve your home’s rating long before the certificate expires.
Do You Need a New EPC Before 10 Years?
Not always.
If your EPC remains valid, you can continue using it when:
- Selling the property
- Letting the property
- Renewing tenancy agreements
- Marketing the property
A new EPC is generally only required after expiry or if you want a more accurate reflection of recent improvements.
Reasons to Get a New EPC Early
Many London property owners choose to renew their EPC before the 10-year period ends.
1. Major Energy Efficiency Improvements
You may have installed:
- Double or triple glazing
- Solar panels
- New boiler systems
- Heat pumps
- Loft insulation
- Wall insulation
These improvements can significantly increase your rating.
2. Increase Property Value
A higher EPC rating can make your property more attractive to buyers and tenants.
3. Meet Rental Regulations
Landlords must ensure their properties meet minimum energy efficiency requirements before letting them. An updated EPC can help demonstrate compliance.
4. Support Green Financing Applications
Many lenders now consider EPC ratings when offering green mortgages or energy improvement financing.

What Happens When an EPC Expires?
An expired EPC cannot be legally used for:
- Selling a property
- Renting a property
- Marketing a property
If you attempt to market your property without a valid EPC, you may face delays and potential compliance issues. Estate agents and letting agents typically require a valid certificate before listing.
Can You Sell a House With an Expired EPC?
No.
Before marketing a property for sale, a valid EPC must be available to prospective buyers. If your EPC has expired, you’ll need to arrange a new assessment.
Fortunately, EPC assessments are generally quick and affordable.
