Calculated on the net present value of the lease rent. Long Class A leases attract material SDLT — typically 1% on the NPV above a threshold. Front-loaded relative to occupancy cost.

Why this matters for Class A leasing

Stamp duty land tax (SDLT) is part of the tax 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.
