Key Takeaways

  • The English Devolution and Community Empowerment Act 2026 received Royal Assent on 29 April 2026.
  • The Act introduces major changes to upwards-only rent reviews in qualifying business tenancies in England and Wales.
  • The new rules are contained in section 100 and Schedule 37, which amend the Landlord and Tenant Act 1954.
  • When the relevant provisions come into force, affected variable rent reviews will no longer operate only upwards.
  • Existing leases are generally protected by transitional provisions, although variations and renewal arrangements require careful consideration.
  • The new rent-review regime is not yet in force — a commencement date must be appointed by regulations.

Commercial lease changes 2026 represent one of the most significant reforms to commercial rent reviews in England and Wales for many years. The English Devolution and Community Empowerment Act 2026 received Royal Assent on 29 April 2026, amending the Landlord and Tenant Act 1954 by introducing new Landlord and Tenant Act 1954 rules around upwards-only rent reviews.

The headline change is the restriction of upwards-only rent reviews in affected business tenancies. Traditionally, many commercial leases have allowed rent to increase following a review but prevented it from falling. The new legislation changes that position for leases and arrangements within its scope.

However, landlords and tenants need to understand an important point: Royal Assent does not mean the new rent-review regime immediately applies. The relevant provisions require commencement regulations. That makes careful legal advice particularly important for leases being negotiated during this transitional period.

What are the commercial lease changes in 2026?

The commercial lease changes 2026 introduce a statutory restriction on upwards-only variable rent reviews in affected business tenancies. When the provisions commence, a qualifying review mechanism cannot effectively require the reviewed rent to remain above the amount produced by the applicable rent-review calculation simply because the previous rent was higher.

The changes are introduced through:

What is an upwards-only rent review?

An upwards-only rent review allows commercial rent to increase, or remain unchanged, at the review date but prevents it from decreasing. Traditionally, an open-market review might set the new rent at the higher of the existing passing rent or the property's current open-market rental value.

For example:

Market Position Traditional Upwards-Only Review
Current rent £50,000
Market rent rises to £60,000 Rent becomes £60,000
Market rent falls to £45,000 Rent remains £50,000

This structure has historically provided landlords and investors with greater certainty over future rental income. Learn more about how commercial rent reviews work.

Does the 2026 Act ban all commercial rent increases?

No. The 2026 Act does not freeze commercial rents or prevent landlords from increasing rent. Instead, the legislation targets certain variable rent-review mechanisms that prevent downward movement. Where the statutory rules apply, the contractual mechanism cannot simply impose an upwards-only outcome contrary to the new regime.

This distinction is important. Commercial rents can still potentially increase considerably where the relevant calculation justifies an increase. The legislation is better understood as restricting upwards-only rent review mechanisms, rather than banning rent increases altogether.

Which rent review mechanisms could be affected?

The new regime is capable of affecting several common variable commercial rent-review structures where the future rent is not fixed or ascertainable when the lease is granted. This can include open-market, index-linked and turnover-based mechanisms, depending on how the particular lease provisions operate.

Potentially affected mechanisms include:

Fixed or stepped rents require separate consideration because the future rent may already be ascertainable when the lease is granted. For detailed guidance, speak to our rent review solicitors.

When do the new commercial lease rules take effect?

The new upwards-only rent review restrictions are not yet in force. Although the English Devolution and Community Empowerment Act 2026 received Royal Assent on 29 April 2026, the relevant Part 5 provisions require commencement regulations before the new regime becomes operative.

This is particularly important for businesses reading about a 2026 ban. The law has been enacted, but landlords and tenants should not assume that every upwards-only rent review clause signed today is already prohibited. The commencement date should therefore be checked whenever a lease is being negotiated, varied or renewed.

Will existing commercial leases be affected?

Existing commercial leases are generally protected by transitional provisions, meaning the legislation is principally directed at relevant leases granted, or certain rent-review provisions introduced by variation, after commencement. However, the transitional rules are detailed, and renewal arrangements and later variations require particular care.

Landlords should avoid assuming that an existing lease can simply be varied after commencement without considering the new legislation. Likewise, tenants should not assume that an existing upwards-only clause automatically becomes an upwards-and-downwards review. The precise facts and documentation matter.

What changes for new commercial leases?

Once the new provisions commence, landlords and tenants entering affected new business tenancies will need rent-review clauses drafted to comply with the new statutory regime. A clause designed to prevent the reviewed rent falling below a contractual floor may be ineffective to the extent that it produces the prohibited result.

This could affect negotiations over:

Landlords may consequently reconsider how rental risk is priced into a lease. Tenants should equally avoid assuming that the reform necessarily makes every lease financially more favourable. Our solicitors for new commercial lease transactions can guide you through the drafting.

What changes for renewed commercial leases?

Renewed commercial leases require particular attention because Schedule 7B extends the new regime to certain arrangements under which a new tenancy can be required. The legislation is designed to prevent parties avoiding the rent-review restrictions simply by fixing prohibited rent terms through qualifying renewal arrangements.

Relevant arrangements may include certain:

Importantly, the transitional provisions contain special rules concerning certain tenancy renewal arrangements entered into on or after 17 March 2026. For tailored advice, speak to our commercial lease renewal solicitors.

Does the change affect contracted-out commercial leases?

The legislation is broader than simply protected tenancies enjoying security of tenure. Its definition of a business tenancy can include tenancies that would fall within Part II of the Landlord and Tenant Act 1954 but for particular circumstances, so contracting out should not automatically be treated as avoiding the new rent-review rules.

This is an important distinction between security of tenure, which concerns renewal rights, and rent-review regulation, which concerns how certain rent-review mechanisms operate.

What should landlords do before granting or renewing a lease?

Landlords negotiating new or renewed commercial leases should review proposed rent provisions now rather than waiting until commencement. Heads of Terms, agreements for lease, options and renewal arrangements may all need consideration because transitional protection can depend on when particular arrangements were entered into.

Landlord checklist

  1. Is the property being let for business use?
  2. Is the proposed rent review variable?
  3. Can the rent currently move only upwards?
  4. Is an agreement for lease involved?
  5. Are renewal or option rights being granted?
  6. Could completion occur after commencement?
  7. Are existing leases being varied?
  8. Does the drafting remain commercially appropriate under the new regime?

Our commercial lease solicitors for landlords can help you structure leases that remain robust and compliant.

What should business tenants check?

Business tenants should understand both the current lease provisions and the forthcoming statutory regime before committing to new premises or renewal terms. Particular attention should be given to rent-review formulas, minimum rents, indexation, break rights and the date on which contractual arrangements are entered into.

Tenants should ask:

Conclusion

The English Devolution and Community Empowerment Act 2026 introduces restrictions on upwards-only variable rent reviews through amendments to the Landlord and Tenant Act 1954.
