Check Your Home's Energy Rating — Free

An Energy Performance Certificate (EPC) rates a property's energy efficiency from A (most efficient) to G (least efficient). It includes estimated energy costs and recommendations for improving efficiency. EPCs are required whenever a property is built, sold, or rented in the UK.

You can check your EPC rating for free using our search tool at the top of this page. Simply enter your postcode and we'll show you the current energy rating for properties in your area. The data comes from the official government EPC register.

Yes, checking your existing EPC is completely free. The government maintains a public register of all EPCs, which our tool searches. However, if you need a new EPC assessment, you'll need to hire a qualified assessor, which typically costs £35–£120.

An EPC is valid for 10 years from the date it was issued. After 10 years, you'll need a new assessment if you want to sell or rent the property. You can get a new EPC at any time if you've made energy improvements and want an updated rating. Read our full guide on EPC validity.
