PRACTICE & STANDARDSbeginnerEPC
Definition
A document rating the energy efficiency of a building on a scale from A (most efficient) to G (least efficient). In the UK, EPCs are required when a property is built, sold, or let. The rating is based on the building's fabric, systems, and estimated running costs.
Example
Since 2020, UK landlords cannot let a property with an EPC rating below E — and proposed future legislation may require a minimum of C, driving major retrofit investment across the housing stock.
