An EPC is valid for 10 years from the date of issue. The certificate belongs to the property, not the owner, so a previous owner's certificate is legally usable if it is still within the 10-year window. You need a new one when the existing certificate expires, when you have made improvements worth recording, or when a mortgage lender requires a current rating.
How the 10-year validity works
The validity period begins on the date the certificate is lodged on the government register, normally the same day the assessor submits the data. The exact expiry date is shown on the certificate itself and on the government EPC register (find-energy-certificate.service.gov.uk, searchable free by postcode).
The certificate is property-specific. It remains on the register regardless of who owns or lets the property. A new owner, new landlord, or new managing agent can use the same certificate for selling or letting until it expires.
When you must get a new EPC
Selling the property
The EPC must be commissioned before marketing. If the existing certificate has expired, you cannot legally list the property without commissioning a new assessment first. See our EPC for selling guide for timing detail.
Renting the property
A valid in-date EPC is required before every letting. If the certificate expires during a tenancy, you do not need to renew immediately, but you will need a valid EPC before the next letting or renewal. For MEES purposes, local authorities may require evidence of a current EPC to confirm compliance.
MEES compliance
The PRS Exemptions Register requires a valid EPC as part of demonstrating MEES compliance. Some landlords with expired EPCs have been unable to confirm their property meets the minimum standard, creating unexpected compliance problems. See our MEES guide for full detail.
HMO licence renewal
HMO licences typically require a valid EPC as part of the renewal documentation. An expired EPC can block licence renewal.
When you might want a new EPC without being legally required
After making improvements
A new EPC after cavity wall insulation, loft insulation, a boiler replacement, or solar PV installation reflects the improved specification. The new certificate:
- Shows the higher rating permanently on the government register
- Supports MEES compliance at the improved band
- Can unlock better buy-to-let mortgage rates (see below)
- Strengthens a property listing before sale
There is no minimum gap, commission a new assessment immediately after works are complete.
Before the certificate lapses
If your EPC is approaching expiry and you plan to sell or re-let shortly, commission a new assessment in advance rather than letting it expire and creating urgency. Allow at least one week for scheduling and delivery.

EPC validity and mortgage lenders
This is an area that has changed significantly since 2023. Several major UK buy-to-let mortgage lenders now factor EPC ratings into their lending criteria, beyond simply checking that a valid EPC exists:
Rate preferencing: NatWest, Barclays, and Halifax buy-to-let products (as of 2025–2026) offer preferential interest rates for properties rated C or above, typically 0.1–0.3% lower than for D-rated equivalents. On a £250,000 interest-only buy-to-let mortgage, 0.2% represents £500 per year.
Lending restrictions: Some specialist buy-to-let lenders restrict lending on properties below EPC E. An expired EPC is treated as a missing EPC, the lender cannot confirm the current band.
Future policy signal: The Bank of England's Prudential Regulation Authority has published guidance encouraging lenders to consider EPC ratings in credit risk assessments. Expect the direction to tighten further.
Practical implication: If you are remortgaging a buy-to-let property and the EPC is D-rated or below, commissioning a new assessment after improvements may improve your mortgage rate by enough to justify the improvement cost independently of any sale or compliance requirement.
How to check your EPC expiry date
- Go to find-energy-certificate.service.gov.uk
- Search by postcode, all EPCs ever issued for properties in that postcode appear in a list
- Select your property
- The certificate shows date of assessment and date of expiry at the top
This is a free public service; no account required. If no EPC appears for your property, one has never been lodged (common for pre-2008 properties, which were phased into the EPC requirement between 2007 and 2009).
EPC validity in common scenarios
| Scenario | Valid? | Action |
|---|---|---|
| Selling, EPC issued 6 years ago, no changes made | Yes | None, use existing certificate |
| Re-letting after void, EPC expired last month | No | Commission new assessment before listing |
| Buying at auction, previous EPC is 9 years old | Yes (for now) | Plan reassessment within 12 months |
| Just fitted cavity wall insulation, want rating updated | Existing still valid | Optional, commission new assessment for improved rating |
| HMO licence renewal, EPC expired | No | New assessment required for renewal |
| New-build never previously marketed | None exists | Commission before first sale or let |
Can an EPC be transferred between properties?
No. An EPC is issued for a specific property at a specific address. It cannot be transferred, amended, or reused for a different address. Converted properties (a house split into flats) require a separate EPC for each new unit.
We cover all London boroughs and can typically schedule an assessment within 1–2 days. See our pricing page for costs by property size, or book directly.
Frequently asked questions
- Yes, if it is less than 10 years old. The expiry date is shown on the certificate and on the government EPC register. A previous owner's EPC is valid for the property, EPCs are property-specific, not owner-specific.
- Yes. The certificate becomes invalid on its tenth anniversary. You must commission a new assessment before selling or letting after expiry.
- Yes, at any time. If you have made improvements, insulation, a new boiler, solar panels, a new assessment will show the updated (typically higher) rating. The new certificate replaces the old one on the government register immediately.
- If the EPC is within its 10-year window, you can use it for selling or letting. If it has expired, commission a new one before marketing. Check the expiry date on the government register.
- For sales: a £200 fixed penalty for failure to provide an EPC. For rentals: up to £5,000 per property for letting without a valid EPC, rising to £30,000 for prolonged breaches under MEES.
