Energy Performance Certificates
What an EPC tells you, when you need one, and how to improve your rating.
An Energy Performance Certificate rates a home’s energy efficiency from A, the most efficient, to G, the least. It also estimates running costs and recommends improvements.
When you need one
You need a valid EPC before you market a home for sale or to let. A certificate lasts for ten years. You can look up any existing certificate for a property on the GOV.UK register.
In England and Wales, most privately rented homes must have a rating of at least E.
What the certificate shows
- The current energy efficiency rating and the potential rating
- Estimated energy costs
- Recommended improvements, with indicative costs and savings
Getting an assessment
EPCs are produced by accredited domestic energy assessors. The assessor’s accreditation scheme is shown on the certificate. An assessment usually takes about an hour, depending on the size of the property.
Improving your rating
Insulation, efficient heating and controls, low-energy lighting and renewable technologies all improve a rating. The recommendations on your certificate are the best place to start.
