What Is An Energy Performance Certificate (EPC)?

EPCs tell you how energy efficient a building is and give it a rating from A (very efficient) to G (inefficient). EPCs let the person who will use the building know how costly it will be to heat and light, and what its carbon dioxide emissions are likely to be.

The EPC will also state what the energy-efficiency rating could be if improvements are made and highlights cost-effective ways to achieve a better rating. Even if you rent your home, some improvements noted on the EPC may be worth implementing, such as switching to more energy-efficient light bulbs.

EPCs are valid for 10 years from when issued.

Who Needs One?

All domestic and commercial buildings in the UK available to buy or rent must have an Energy Performance Certificate (EPC).

Are There Any Exceptions?

You don’t need an Energy Performance Certificate (EPC) if you can demonstrate that the building is any of these:

  • listed or officially protected and the minimum energy performance requirements would unacceptably alter it
  • a temporary building only going to be used for 2 years or less
  • used as a place of worship or for other religious activities
  • an industrial site, workshop or non-residential agricultural building that doesn’t use much energy
  • a detached building with a total floor space under 50 square metres
  • due to be demolished by the seller or landlord and they have all the relevant planning and conservation consents

Vacant buildings and demolition

A building is also exempt if all of the following are true:

  • it’s due to be sold or rented out with vacant possession
  • it’s suitable for demolition and the site could be redeveloped
  • the buyer or tenant has applied for planning permission to demolish it
