Full definition

Cat B is the tenant's interior build — workplace strategy, partitions, finishes, joinery, AV, security, and furniture. Per-sqft Cat B budgets in 2026 range from £80 (basic) to £400+ (trophy) in London Class A.

Why this matters for Class A leasing

Cat B is part of the construction 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.
