An Energy Performance Certificate (EPC) provides a clear rating of a building’s energy efficiency, helping property owners, buyers, and tenants understand energy usage and potential improvements. As part of UK Building Regulations requirements, EPCs are essential for new builds, sales, and rentals. They ensure compliance while highlighting opportunities to improve energy performance, reduce running costs, and lower environmental impact.
