Energy use and carbon dioxide emissions

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

The rating measures the energy efficiency and carbon emissions 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.

 

What does an EPC look like?

Information about energy efficiency and carbon emissions is summarised in two charts that show the energy and carbon dioxide emission ratings. The charts look similar to those supplied on fridges, washing machines, light bulbs or new cars.

 

What are the main factors that will affect the EPC rating?

  • The position of a property and how many exposed walls are losing heat
  • The type of walls as solid walls are less efficient than cavity walls
  • The age of a property and how building regulations comply will determine the level of insulation installed
  • The type and age of the central and water heating system, the type of fuel used and the types of controls (eg programmer, room thermostat, TRVs etc)
  • The presence and age of any double glazing
  • The presence and amount of insulation in a loft space,in cavity walls, under floors, or applied to solid walls
  • The presence of any micro generation such as solar water heating or photovoltaic panels

 

The recommendation report

EPCs also provide a recommendation report showing what you could do to reduce the amount of energy you use and your carbon dioxide emissions.The recommendations are split into three types. These are lower cost, higher cost and further measures. The report includes:

  • suggested improvements, like fitting loft insulation or replacing an old boiler 
  • possible cost savings per year, if the improvements are made
  • how the recommendations would change the energy and carbon emission rating of the property

You don’t have to act on the recommendations.  However, if you decide to do so, it could make your property more attractive for sale or rent by making it more energy efficient.

 

Which buildings need an EPC?

An EPC is required when a building is constructed, rented or sold. A building will need an EPC if it has a roof and walls and uses energy to ‘condition an indoor climate’. This means it has heating, air conditioning or mechanical ventilation. For example, a garden shed would not need an EPC if it doesn’t have any heating.

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 do not need a domestic 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 metres squared that are not 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
