Unlike residential tenancies (which from May 2026 can only be increased via Section 13 notices), commercial rent increases in England are governed by the negotiated terms of the lease and the Landlord and Tenant Act 1954 (effective 1 October 1954), alongside the newly enacted English Devolution and Community Empowerment Act 2026 (effective 29 April 2026). There is no statutory cap on commercial rent, but renewal rent is strictly regulated by the County Court under statutory valuation principles.

Common Rent Review Mechanisms

1. Open Market Rent Review

The most traditional English commercial review mechanism. At specified intervals (typically every 3 or 5 years), the rent is reset to reflect the current open market value of the premises. If the parties cannot agree on the new rent, the dispute is referred to an independent surveyor or arbitrator for determination.

2. Upwards-Only Rent Reviews

Historically, most English commercial leases contained upwards-only rent review clauses, meaning the rent at review could only stay the same or increase — it could never decrease, even if the market had declined.

[!IMPORTANT] The 2026 Ban: The English Devolution and Community Empowerment Act 2026 (2026 c. 23) received Royal Assent on 29 April 2026. Once commenced, it will make upwards-only rent review clauses unenforceable in leases falling under Part 2 of the LTA 1954, effectively converting them into "two-way" reviews. Existing leases entered into before commencement are generally protected.

3. Index-Linked Reviews

Rent increases are linked to a specific index, typically the Retail Price Index (RPI) or the Consumer Price Index (CPI). The rent adjusts automatically based on the percentage change in the index over the review period. Some leases include a cap and collar (e.g., minimum 2% increase, maximum 5%).

4. Fixed Increases (Stepped Rent)

The lease pre-defines exact rent amounts for each period, providing certainty for both parties. Common in short-term leases or for the early "rent-free period" transition.

Rent Increases on Lease Renewal (LTA 1954)

When a commercial lease is renewed under the LTA 1954, the County Court (if the parties cannot agree) sets the new rent under Section 34 based on the open market rental value, disregarding the tenant's goodwill and any improvements the tenant has carried out. This statutory valuation ensures that renewal rents reflect market reality rather than arbitrary lease uplifts.
