The Renters' Rights Act 2025: what are the implications for property finance?

The Renters' Rights Act 2025 (the "Act") received Royal Assent in October 2025 and will be implemented in three phases over the course of the next decade.  With the first and most consequential wave of reforms due to take effect on 1 May 2026, the Act represents the most significant restructuring of the private rented sector ("PRS") in a generation. Whilst much of the political and media commentary has focused on the rights afforded to residential tenants, the reforms carry equally profound implications for lenders, sponsors and developers who finance the acquisition and ongoing ownership of residential investment property.
