What The Upwards-Only Rent Review Ban Means For Landlords
Commercial leasing across England and Wales is undergoing one of the most significant legal shifts in decades.
Royal Assent was officially granted to the English Devolution and Community Empowerment Act 2026 on 29 April 2026. Within this landmark legislation lies a statutory ban on upwards-only rent review clauses, introducing a major regulatory reform that fundamentally alters UK real estate asset management.
While full commencement via secondary legislation is awaited, the industry is entering an urgent operational adjustment phase. Understanding what is an upwards only rent review and recognising how this new legal reality impacts valuations, debt structures and lease negotiations is essential for portfolio managers navigating current acquisitions and asset reviews.
What Is An Upwards Only Rent Review?
An Upwards Only Rent Review is a long-standing lease mechanism that recalculates passing rent at specified intervals (typically every five years) by reference to market rates or inflation indices. Under these clauses, the revised rent can either increase or remain at its current level, but it can never fall, even if prevailing market conditions deteriorate.
Historically, upwards-only reviews have provided landlords with greater certainty over contractual rental income, although voids, tenant defaults and other risks can still affect investment performance.
What Is Changing And When
Under the Act, any lease clause seeking to prevent rent from falling below the passing rate during a review will be rendered unenforceable in law. Landlords will no longer be permitted to rely on contract terms that lock in artificially high rents when local open-market levels drop.
Key operational timelines include:
- Statutory Enactment: Royal Assent was achieved on 29 April 2026.
- Implementation Window: Full enforcement is expected following government consultations regarding caps, collars and technical exceptions.
- Retrospective Anti-Avoidance Date: Crucially, the legislation targets future renewals granted pursuant to options or agreements executed on or after 17 March 2026.
This means that while the main ban is not yet fully in force, options and agreements signed today are already caught by the upcoming statutory override.
What The Ban Actually Covers
The scope of the prohibition is broad, capturing commercial business tenancies falling under Part 2 of the Landlord and Tenant Act 1954 across retail, industrial, logistics and office sectors.
Review Mechanisms
The statutory override applies to most variable rent review mechanisms. Open-market reviews, index-linked reviews (such as RPI or CPI) and turnover-based rent calculations must all allow for downward adjustments if market values or indices fall.
However, fixed stepped rents -where specific, predetermined rental increases are explicitly written into the lease from day one – remain fully compliant because future liabilities are fixed at execution.
Tenant Trigger Rights
Historically, lease wording frequently reserved the sole right to initiate a rent review to the landlord. The Act eliminates this advantage by granting tenants explicit statutory rights to trigger a review via written notice. Landlords can no longer avoid downward rent adjustments simply by choosing not to initiate the review process.
Anti-Avoidance Framework
Anti-avoidance provisions address attempts to preserve prohibited terms through connected arrangements, including certain renewal options. The legislation also deals with relevant requirements in superior leases concerning subletting.
Why Existing Leases Stay Unaffected And Portfolio Impact
Crucially, the legislation is not fully retrospective and does not dismantle existing, executed leases granted before the commencement rules take effect. Legacy contracts retain their original Upwards Only Rent Review protections until contractual expiry.
This creates a distinct bifurcation in market valuations:
- Legacy Contracts: Executed leases with valid upward-only protections will likely command a premium among yield-focused institutional buyers due to their guaranteed income stability.
- New Lettings and Renewals: Post-ban leases will carry higher income volatility, directly influencing debt financing covenants, loan-to-value calculations and initial exit yield assumptions.
Understanding what an upwards only rent review is in this shifting legal landscape helps asset managers audit portfolio exposure before legacy leases expire.
Strategic Considerations Before Agreeing Early Re-Gears
As property directors adjust to these legal realities, handling tenant requests for early lease restructuring demands careful analysis.
Key strategic considerations include:
- Protecting Legacy Value: Surrendering an existing lease to grant a new long-term agreement will bring the asset under the post-ban regime, permanently removing its legacy upward-only protection.
- Structuring Fixed Stepped Rents: Replacing variable market reviews with agreed annual stepped uplifts offers a reliable mechanism to ensure predictable income growth.
- Evaluating Lease Lengths: Shorter lease terms may offer opportunities to reset rents, but can also increase reletting costs and void risk. Assess the trade-off against tenant demand and covenant strength.
Seeking advice from a commercial property investment agent ensures portfolio decisions preserve long-term capital performance during this transition.
