Unlike residential tenancies (which from May 2026 can only be increased via Section 13 notices), commercial rent increases in England are governed almost entirely by the rent review provisions negotiated within the lease. There is no statutory cap, no mandatory notice period, and no government tribunal for commercial rent disputes.

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] Proposed Ban: In July 2025, the UK Government announced its intention to ban upwards-only rent review clauses in commercial leases, included in the English Devolution and Community Empowerment Bill. If enacted, this would represent a seismic shift, allowing rents to move both up and down at review.

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 court (if the parties cannot agree) sets the new rent based on the open market rental value, disregarding the tenant's goodwill and any improvements the tenant has carried out.
