The short answer
An Energy Performance Certificate is valid for 10 years from the date it is lodged on the national EPC Register. You do not have to renew it during that period, even if you sell or re-let the property, as long as a valid certificate already exists. You only need a new EPC when the existing one expires, or sooner if you want to reflect improvements you have made — for example after adding insulation, a new boiler or solar panels — because a fresh assessment can show a higher rating. You can check the date a certificate was issued and when it expires for free on the EPC Register using the property's postcode.
The 10-year rule is the single most useful EPC fact: if a valid certificate already exists, you usually do not need a new one. Here is when that changes.

What the 10-year rule means
An EPC lasts 10 years from issue. During that time it stays valid for selling or letting the same property, so if you buy a home with five years left on its certificate, you can usually sell or rent it on that certificate without commissioning a new one. The certificate only stops being usable when it expires — at which point a new sale or letting will require a fresh assessment by an accredited domestic energy assessor.
| Situation | Need a new EPC? |
|---|---|
| Valid EPC already exists | No — use the existing one |
| EPC has expired | Yes — commission a fresh one |
| Selling with a valid EPC | No |
| Made major upgrades | Optional — to show a higher rating |

When to renew before it expires
You are not obliged to renew early, but it can be worth it. If you have improved the property — loft or wall insulation, a new efficient boiler, double glazing or solar panels — a fresh EPC can record a higher band, which helps when selling or letting and may matter for the Minimum Energy Efficiency Standards on a rental. If nothing has changed, there is usually no benefit to renewing early. You can confirm an existing certificate's issue and expiry dates for free on the EPC Register before deciding.

We'll match you with an accredited domestic energy assessor who can produce a fresh certificate and lodge it on the EPC Register.
