The UK buy-to-let market is experiencing a significant downturn, with an estimated 30,000 small landlords exiting the sector in the year to April 2025. This marks the first decline in five years and is attributed to a "complex and costly legislative environment," according to experts. Profitability for small landlords has also dipped, with declared property income falling by £10 million, reversing a growth trend since 2021. The average small landlord reported only £20,500 in rental income, a mere £200 increase from the previous year, unadjusted for inflation. London landlords saw the largest income decrease, falling by £350 million, while the Channel Islands experienced a nearly 24% collapse in small landlord income. The South East of England saw a reduction of 7,000 small landlords, and Scotland lost approximately 4,000.
Several factors are contributing to this exodus. The Renters' Rights Act, which came into force in May, is expected to accelerate landlord departures. Stamp duty on additional residential properties increased from 3% to 5% in autumn 2024, further impacting buy-to-let investments. Additionally, tax on property income is set to rise in April 2027, with basic-rate taxpayers paying 22%, higher-rate taxpayers 42%, and additional-rate taxpayers 47%. Higher interest rates have also squeezed margins, with about 80% of buy-to-let mortgages being interest-only. The average fixed-rate buy-to-let mortgage stood at 5.47% in August and September, with forecasts suggesting the base rate will remain at 3.75% in 2026, possibly with a 0.25 percentage point rise.
Landlords also face increasing operational costs, including a requirement for all rental homes to achieve a minimum energy performance certificate rating of C by 2030, adding to the over 170 regulations they must now adhere to. Consequently, interest in becoming a buy-to-let landlord has fallen across most major UK cities. Research indicates that only 3.9% of landlords plan to expand their portfolios in the next 12 months, while 13% plan to reduce holdings and 14.2% intend to leave the market entirely. This means seven landlords are retreating for every one expanding. Despite these challenges, over half of landlords still view residential property as a sound long-term investment, with scarcity leading to a 3.7% rise in average UK private rents to £1,393 in the 12 months to July 2026. However, continued tax pressures are expected to constrain rental supply, ultimately leading to higher rents for tenants.
