What the Renters' Rights Act means for London development sites.

The Renters' Rights Act received royal assent in October 2025. From 1 May 2026, Section 21 no-fault evictions are abolished and all tenancies become periodic. For London's private landlords, the calculus has changed.

Many landlords — particularly those with HMOs, multi-lets, and properties in high-density rental postcodes — will exit the market rather than operate under the new rules. When landlords exit, assets move. Sites that have been held become available.

DevSource tracks every planning application, dissolved company signal, and ownership pattern across 59,000+ London sites — updated nightly. The Landlord Exit filter surfaces properties in the highest-concentration rental postcodes with active development signals.
