For years, Britain's buy-to-let market has been dominated by stories of landlords selling their properties amid fears of a costlier rental market. Higher mortgage rates, tougher tax rules, mounting regulation, and proposed rental reforms have fuelled predictions of a mass exodus from the private rental sector.
Prop Invest UK reported that in 2025, around 93,000 landlords left the rental market, and it estimated that another 110,000 are expected to leave in 2026. In addition, many smaller property owners have exited the market amid rising costs, tax changes, and increasing regulation, particularly the Renters' Rights Act. However, despite this decline, the private rental sector continues to house millions of tenants, and many professional landlords are expanding their portfolios rather than retreating.
