Energy Performance Certificates

The Energy Performance Certificate (EPC) gives homeowners, tenants and buyers information on the energy efficiency of the property. It gives the building a standard energy and carbon efficiency grade from ‘A’ to ‘G’, where ‘A’ is the most efficient. The average efficiency grade to date is ‘D’.

What else does the certificate tell you?

The ratings are measured using the same calculations for all homes, so you can compare the energy efficiency of different properties.

Part of the EPC is a report which will list the potential rating that your home could achieve, if you made the recommended changes. The report lists:

suggested improvements (such as fitting loft insulation)
the approximate cost
possible cost saving per year if the improvements are made
how this would change the energy and carbon rating
You can use this information to:

cut your fuel bills
improve energy performance in your home
help cut carbon emissions
help you choose a more energy efficient home to rent or buy
You do not have to act on the recommendations contained in the report. However, if you decide to do so, then it could make your property more attractive for sale or rent by making it more energy efficient.

How do you get an EPC?

EPCs can only be produced as a result of a survey by an ‘accredited’ Domestic Energy Assessor. EPCs are used to collect standard information on the property – for example, its size and hot water/heating systems. The information is then fed into a government-approved software programme that produces the EPC.
