# EPC (Energy Performance Certificate)

*Tax / regulatory · UK*

## Short definition

UK statutory energy rating, A-G scale.

## Full definition

Statutory in the UK at lease and sale. Since 2023, commercial property cannot be let with an [EPC rating](/glossary/epc-rating) below E (extending to C in 2027 and B in 2030 — subject to confirmation). EPC ratings now drive a measurable rent premium and a hard market exit for non-compliant assets.

## Why this matters for Class A leasing

EPC (Energy Performance Certificate) is part of the tax / regulatory vocabulary that institutional [Class A](/glossary/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](/topics/cross-border-expansion) occupiers can translate quickly.
