A domestic Energy Performance Certificate, which is also known as an EPC, is a certificate that confirms the energy efficiency rating of your home.
During an EPC assessment, a tradesperson will thoroughly survey your home, looking at your heating system, insulation, lights, wall thickness and other areas that can impact energy efficiency.
After an EPC assessment, your tradesperson will calculate an efficiency rating from A-G, with A being the most energy efficient, and G being the least energy efficient. You'll then be presented with an EPC certificate which confirms the rating.
You must have a valid EPC before you can sell or rent out your property. An EPC assessment must be carried out by a qualified professional, and the certificate is valid for 10 years.
