Energy Performance Certificates
Energy Performance Certificates (EPCs) 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. Find out what EPCs look like and what they contain.
Energy Performance Certificates – what they tell you
How to get an EPC
- Information on your home’s energy use and typical energy costs
- A recommendation report with suggestions to reduce energy use and save money
- Details of the person who carried out the EPC assessment
- Who to contact if you want to make a complaint
Energy use and potential savings
EPCs carry ratings that 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 were put in place.
The rating measures the energy efficiency of your home using a grade from ’A’ to ’G’. An ’A’ rating is the most efficient, while ’G’ is the least efficient. The average efficiency grade to date is ’D’. All homes are measured using the same calculations, so you can compare the energy efficiency of different properties.
The recommendation report
EPCs also provide a detailed recommendation report showing how you could reduce the amount of energy you use and your carbon dioxide emissions. The report lists:
- Suggested improvements, like fitting loft insulation
- Possible cost savings per year, if the improvements are made
- How the recommendations would change the energy efficiency rating of the property
- Which improvements may be eligible for funding through the Green Deal (for more information, see ’The Green Deal’ section further down this page)
You don’t have to act on the recommendations in the recommendation report. However, if you decide to do so, it could make your property more attractive for sale or rent by making it more energy efficient.
What an EPC looks like
Information about energy efficiency is summarised in a chart that shows the energy efficiency rating. The chart looks similar to those supplied on electrical appliances, like fridges and washing machines. To see an example of an Energy Performance Certificate, use the link below.
How to get an EPC and how long they’re valid for
An EPC is valid for ten years
You should receive an EPC when you enquire about buying or renting a home. You’ll need to provide one if you are selling or letting your home. An EPC is valid for ten years.
See ’Getting an Energy Performance Certificate’ for information about how and when to get an EPC and how much they cost.
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.
For more details of when and which types of buildings require an EPC, read ’Improving the energy efficiency of our buildings’.
Which buildings don’t need an EPC
The following buildings don’t need an EPC when they are built, rented or sold:
- Places of worship
- Temporary buildings that will be used for less than two years
- Standalone buildings with total useful floor area of less than 50 square metres that aren’t used to provide living accommodation for a single household
- Industrial sites, workshops and non-residential agricultural buildings that don’t use a lot of energy
- Holiday accommodation that’s rented out for less than 4 months a year or is let under a licence to occupy
Comparing your home’s EPC to other homes
You can look at the EPCs of other properties on the EPC register website. This lets you compare your home’s energy performance with that of similar homes free of charge.
If you don’t want other people to be able to see your EPC on the EPC register, you can opt out.
