If you’re thinking of selling or renting your home out it is now by law that you need to make sure your home has an Energy Performance Certificate (EPC).

The EPC certificate will basically tell you how energy efficient your home is, how much energy your home is using, how much more efficient it could be by following recommendations & it also gives you a score relating to how much carbon your property is generating.

The Commerical EPC, which is valid for 10 years, will give you a good idea of how expensive the property will be to run, in terms of your gas and electricity bills, energy efficient measures & what measures you may have to take to making the property as energy efficient as possible

A typical inspection takes around one to two hours to carry out, depending on the size and layout of the property. After the energy assessor has carried out the report they will then use software to calculate the energy rating for the property. Two readings are then given

– One states the level of efficiency that your home is currently achieving

– The second suggests what level of efficiency your home could be achieving if you were to put energy-efficient measures in place.

The energy efficiency rating is a measure of the overall efficiency of a home. The higher the rating the more energy efficient the home is and the lower the fuel bills will be.

Colour coding & the A-G scale

EPCs carry ratings on energy use and carbon dioxide emissions. The energy efficiency rating is colour-coded from green to red, with the green end of the scale indicating that the home is very energy efficient, with lower running costs, and the red end of the scale indicating it is not energy efficient and has higher running costs.


As you can see there is also a numerical rating from 1 – 100. The bigger the number the more energy efficient the home is and the lower the fuel bills will be. The rating scale is also alphabetised, running from A to G:

·       A (Dark green) is highly efficient

·       G (Red) is low efficiency

Most homes appear around grade D which is the average.

The performance of a property is rated in terms of the energy used per square metre of floor area; the energy efficiency based on fuel costs; and the environmental impact based on CO2 emissions. The numbered arrows show the current rating based on the existing energy performance of the property and the potential rating if the suggested improvements are implemented.

Key elements used to produce the report

The type of things the assessor will take into consideration when compiling the report are the walls, loft insulation, domestic boiler, hot water tank, radiators, windows for double glazing & so on & then score each against the following: Very Good/Good/Average/Poor/Very Poor

Recommendations to improve the energy efficiency of your home

Finally the assessor will then recommend measures to improve the energy efficiency of your home. These are then divided into lower cost measures of up to £500 & higher cost measures for larger amounts & it will then outline the typical savings you could make per year after the improvements have been made. Typical lower cost improvements are having cavity wall insulation which could save you annually around £400 to higher cost measures like having a new boiler fitted. Further suggestions like having solar heating panels or having double glazing fitted.epc rating

There is obviously no need to act on the recommendations set out in the report however by doing so will make the property more energy efficient & make it more attractive for sale or rent.
