The latest data from HMRC reveals that total rental income for landlords in the UK has plateaued at £59 billion, marking a significant shift after a period of growth since 2020. This stagnation could impact landlords’ financial strategies and the broader mortgage market.

What Are the Key Figures from the Latest HMRC Data?

According to HMRC, rental income has seen a notable increase of 26% from 2020 to 2021, amounting to £12.3 billion. However, this growth has now levelled off. In 2024-25, unincorporated landlords reported an average property income of £20,500, a 24% increase since 2020-21. Approximately 1.3 million landlords earned £10,000 or less, indicating that a significant portion of landlords operates on lower margins.

How Do Different Regions Contribute to Rental Income?

London remains a dominant force in the rental market, with 17% of unincorporated landlords located there, accounting for 28% of all declared rental income. Combined with the South East, these regions represent a third of all landlords and 44% of total rental income. In contrast, areas like the North East contribute only 2%, while Scotland, Wales, and Northern Ireland account for 5%, 3%, and 1%, respectively.

What This Means for the Mortgage Market

The plateau in rental income could signal a need for landlords to reassess their financial strategies. With 87.7% of landlords declaring expenses totalling £34.8 billion, including significant costs for repairs and maintenance, the pressure on profit margins is evident. Investors should be mindful of the declining income from furnished holiday lettings, which fell slightly to £2.46 billion in 2024-25, indicating a potential shift in investment focus. For those considering financing options, reviewing current mortgage rates may be beneficial.
