UK/EU Energy Performance Certificate rating, A (best) to G.

Full definition

EPC is statutorily required on all UK lettings. The 2023 MEES regulations made it unlawful to let buildings rated below E; the bar rises to C in 2027 and B in 2030. Structural risk for any landlord with sub-B Class A stock.

Why this matters for Class A leasing

EPC rating is part of the certifications vocabulary that institutional Class A occupiers, landlords, and advisers use across UK markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the UK definition alongside the global standard so cross-border occupiers can translate quickly.
