A clause providing for annual changes to the rent payable under a lease. The clause is drafted on the basis that the rent will change based on the Retail Prices Index, although a different index can be specified. It provides for both a maximum and minimum increase at each review (often known as a capped and collared review or a capped and floored review).
The standard clause is drafted to fit into standard document commercial leases offered by Practical Law Property but can also be adapted for use in other leases.
