About Energy Performance Certificates

Energy Performance Certificates were introduced in 2007 to meet EU requirements that all buildings being offered for sale or rent must provide information relating to the energy usage of the building and how that may be improved.

The information below is quoted from epc.direct.gov.uk.

EPCs contain:

  • 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 efficiency rating graph for homes image

    Energy use and potential savings

    EPCs carry ratings that compare the current energy efficiency and carbon dioxide emissions with potential figures that your home could achieve. Potential figures are calculated by estimating what the energy efficiency and carbon dioxide emissions would be if energy saving measures were put in place.

    The rating measures the energy and carbon emission 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

    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, click on the sample image.


    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.


    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

    How to get an EPC and how long they’re valid for

    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.
