More than a third of landlords (39%) are considering leaving the rental market completely within the next year, according to the 2025 London Report from landlord insurance provider Simply Business. The Renters’ Rights Bill, which is set to receive Royal Assent this Autumn, is the primary concern for a quarter (26%). From early 2026 the Renters’ Rights Bill should limit rent increases and is designed to improve rental property standards. The long-awaited Renters’ Rights Bill (RRB) is set to drastically change the rental market in the next 12 months. Outside of the Renters Rights Bill, landlords are also facing changes to tax processes as the government’s Making Tax Digital initiative is set to replace annual self-assessments with quarterly returns from April 2026 for individuals with a combined annual income of £50,000.
