The latest data from HMRC reveals that landlord rental income in the UK has plateaued at £59 billion, following a significant rise since 2020. This stagnation comes after a period of growth that saw total property income increase by 26% from 2020 to 2021, largely driven by a surge in the average income reported by landlords and an increase in the number of individuals declaring property income.

What Do the Latest Figures Show?

According to HMRC, the number of unincorporated landlords declaring property income rose from 2.81 million in 2020-21 to 2.88 million in 2024-25. In 2024-25, these landlords reported an average property income of £20,500, marking a £3,900 increase since 2020-21. Notably, around 1.3 million landlords earned £10,000 or less, representing 45% of those declaring income.

How Does Location Impact Rental Income?

Geographically, 17% of unincorporated landlords are based in London, contributing to 28% of all declared rental income. When combined with the South East, these regions account for a third of all landlords and 44% of total rental income. In contrast, the North East reported the smallest share at just 2%, while Scotland, Wales, and Northern Ireland contributed 5%, 3%, and 1% respectively.

What This Means for Landlords and the Mortgage Market

The plateauing of rental income could signal a shift in the mortgage market, particularly for buy-to-let investors. With income growth stabilising, landlords may face challenges in maintaining profitability, which could affect their ability to secure new mortgages or refinance existing ones. As landlords declared £34.8 billion in expenses, including significant costs for repairs and maintenance, the financial market for property investment may become more competitive. For insights on current mortgage rates, landlords might consider reviewing current mortgage rates.

Frequently Asked Questions

Why has landlord rental income plateaued?

The plateau in rental income follows a period of growth driven by rising average property income and an increase in the number of landlords declaring income. Economic factors and market saturation may contribute to this stagnation.

What should landlords consider in light of these figures?

Landlords should assess their financial strategies, particularly regarding expenses and potential refinancing options, as the stability in rental income may impact their investment viability in the current mortgage market.
