An Energy Performance Certificate (EPC) is a mandatory UK document that rates a property's energy efficiency from A (most efficient) to G (least efficient). An EPC is legally required for any property being sold, rented, or built in England, Wales and Northern Ireland, and is valid for ten years.
Also known as: Energy Performance Certificate
EPCs were introduced in the UK in 2007 as part of the EU Energy Performance of Buildings Directive. The rating is based on factors including wall and loft insulation, glazing types, heating system efficiency, hot water systems, and renewable energy installations.
The EPC is produced by an accredited Domestic Energy Assessor (DEA) using the RdSAP methodology (Reduced data Standard Assessment Procedure). The assessor needs measurements of every room, glazing details, heating system information, and a floor plan with Gross Internal Area (GIA) calculations per room.
EPCs are publicly searchable on the UK government EPC register. Estate agents must include the EPC rating in any property marketing material, and the certificate itself must be provided to buyers/tenants at the point of sale or letting.
