The English Devolution and Community Empowerment Act 2026 (“Act”) received Royal Assent on 29 April 2026. Among its most significant commercial property reforms is the proposed prohibition on upwards-only rent reviews (“UORRs”) in business leases.

Although the relevant provisions are not yet in force, the direction of travel is now clear.

The legislation represents a substantial shift in business tenancies practice and may rapidly begin to influence negotiations, valuation assumptions and asset management decisions.

One immediate consequence is that landlords with pending rent reviews under existing leases are likely to rush their conclusion before the ban crystallises.
