Energy Performance Certificate’s Explained

I’m definitely noticing a change in the temperature now so thought this was a good time to write about Energy Performance Certificate’s or ‘EPCs’.

An EPC is a certificate which shows how energy efficient (or not) your property is.  The property is graded A to G, with A being the most efficient and G being the least efficient.  The charts below show the summary that appears on your certificate- giving a simple overview of the efficiency rating:


 The idea is that the better the efficiency, the less it will cost you in energy bills.  Newer homes tend to rate higher than older ones- this is usually because of the use of more modern insulation/ boilers etc which are more energy efficient.  The certificate provides estimated energy usage- giving you an indication of how much it is likely to cost you in energy bills.  This will be shown in a table like the example below:


It is a helpful document, providing suggestions as to measures you can take to improve energy efficiency.  This can range from energy saving lightbulbs to installing thicker insulation.  See the examples below:

It is now a legal requirement to have an EPC before you sell or rent your property.  Your estate agent can help you organise one or you can find a local EPC assessor online.  Typically, this costs around £60. 

If your property has been sold or let since 2008, it should already have an EPC- they are valid for 10 years.  Although, it might be worth ordering a new one if you have made significant energy saving improvements to your home which could make it more appealing to potential buyers. 

Below are links to some useful websites, providing more information about EPCs and energy saving.
