An Energy Performance Certificate (EPC) is a document that provides information about the energy efficiency, running costs and environmental impact of a building.
In order to produce an EPC, a site survey is carried out by an accredited energy assessor who inspects and collects information on many aspects of a building which affect the rating, these include: build date, construction materials, HVAC (Heating, Ventilation and Cooling), hot water heating, lighting, insulation, usage type, and many more.
This information is converted into a rating on a scale A – G. Buildings with a rating close to A produce lower amounts of CO2 and are more efficient than buildings lower down the scale.
An EPC is valid for 10 years.
Do I need an EPC?
If you are selling or renting out a property, and there is not a valid EPC in place, then you are legally required to have one.
An F or G rating means your property in not very energy efficient.
Currently, there are no legal requirements or penalties for buidlings with F or G ratings. However, this is changing on 1st April 2018 as the UK Government introduces the MEES or the Minimum Energy Efficiency Standards.
If you are a landlord or owner wanting to rent out a residential or commercial property, it will soon be law that the building achieves an EPC rating of E or better.
To improve the energy rating, improvements to the buidling will be required. The best person to speak to about what the most cost-effective measures may be is the energy assessor who undertakes the EPC survey.
