Energy Performance Certificates (EPCs)

Energy Performance Certificates give information on how to make your home more energy efficient and reduce your energy costs. All homes bought, sold or rented require an EPC.

An example EPC can be found below:

EPC Example

An EPC contains:

Energy Usage & Potential Energy Savings

EPC ratings compare the current energy efficiency and estimated costs of energy use with potential figures that your home could achieve. Potential figures are calculated by estimating what the energy efficiency and energy costs could be if energy saving measures are put into place.

The rating measures the energy efficiency of your home, graded A-G. An A rating is the most efficient, while G is the least efficient.

Which buildings need an EPC?

An EPC is required when a building is built, rented or sold.

A building is defined as a structure with a roof and walls which uses energy to ‘condition an indoor climate’. This means it has heating, air conditioning or mechanical ventilation.

The building can either be a whole building or part of a building that has been designed or altered to be used separately. If a building is made up of separate units, each with its own heating system, each unit will need an EPC.

The following buildings don’t need an EPC when they are built, rented or sold:
