# Cat A

*Construction · UK*

## Short definition

UK landlord delivery standard — [base building](/glossary/base-building) plus raised floor, ceilings, basic MEP [fit-out](/topics/fit-out-capex)">fit-out.

## Full definition

A Cat A handover provides the tenant with a workable shell — raised floor, suspended ceiling, basic lighting, finished perimeter heating/cooling. The tenant then completes [Cat B](/glossary/cat-b) (partitions, finishes, furniture).

## Why this matters for Class A leasing

Cat A is part of the construction 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.
