What is an Energy Performance Certificate (EPC)?
An EPC is a very useful document that tells you exactly how your house performs, providing an energy efficiency rating from A, which is very efficient all the way down to G, which is not so. It’s a bit like miles per gallon on your car only a measure for your home or business.
How long does an epc last?
Your EPC is valid for 10 years. To arrange an energy performance certificate for your home or business you will need to ensure your property is assessed. Gov.uk have an online energy assessor search tool which you can find here.
So, where did EPC’s come from and why do I need one?
The Energy Performance of Buildings Directive is a European directive that says that houses should be able to demonstrate a level of CO2 and energy efficiency in a document of some kind.
Whenever you get a new house built or you are selling/renting a property you have to have an EPC. An assessment is carried out on your property which looks at factors such as the wall, floor & roof insulation, boiler efficiency, your windows and whether or not they are double glazed and even the lighting in place to understand if it is low energy lighting. These features are put into a programme, calculated and redistributed as a number, which corresponds to a letter. This can be difficult in existing buildings because quite a few assumptions can be made. It’s easier in new builds because you can start from scratch and utilise Standard Assessment Procedure (SAP) calculations.
The average score of existing buildings is 60 which is the equivalent of Band D whereas new build averages out at 80 which is a Band B. So, better more efficient scores for new constructions, which is perhaps as you would expect.
Why bother with EPC’s?
The ‘Every Home Matters’ is the new name for The Bonfield Review which looks at existing buildings and ways in which the Great British public can be incentivised to improve the energy efficiency performance of their homes. Check out some of the things being talked about in the video.
