Why this matters for Class A leasing

DEC (Display Energy Certificate) is part of the tax / regulatory 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.
