The UK mortgage market has shown significant recovery in 2025, with notable shifts in lender positions and lending activities, particularly in the buy-to-let sector. As total gross lending reached a substantial increase from the previous year, the implications for landlords, borrowers, and brokers are substantial.
How Did Major Lenders Perform in 2025?
In 2025, Santander emerged as the standout performer in gross lending, experiencing a remarkable increase. Other major lenders also reported significant growth, with Barclays, NatWest, HSBC, and Nationwide all showing strong performance. Despite this growth, Lloyds recorded the slowest increase among the big six lenders but remains the largest lender in terms of both gross lending and outstanding balances.
What Changes Occurred in the Buy-to-Let Mortgages Sector?
The buy-to-let sector experienced even stronger growth, with gross lending rising significantly. Santander led this segment with a remarkable increase in buy-to-let gross lending, moving up in the rankings among lenders. Other lenders, including NatWest and HSBC, also saw significant increases in buy-to-let lending, while Kensington Mortgage Company improved its position as well.
What Does This Mean for Landlords and Borrowers?
The substantial growth in buy-to-let lending indicates a robust demand for rental properties, presenting an attractive opportunity for landlords. With Santander significantly increasing its buy-to-let lending while Barclays experienced a decline in its buy-to-let balances, it highlights a shift in how lenders are managing their portfolios. This trend suggests that landlords may benefit from exploring lenders outside the traditional big six, particularly those focusing on specialist and buy-to-let lending.
For brokers, the data underscores the importance of staying informed about lender performance and market trends. The increase in gross lending, juxtaposed with a slower growth in total mortgage balances, indicates a significant level of activity driven by new lending, refinancing, and product switching. This churn may present opportunities for brokers to assist clients in finding competitive remortgage options or new buy-to-let products. For more insights, check out our buy-to-let mortgage rates.
What Should Investors Watch Next?
Investors should keep an eye on the evolving competitive dynamics among lenders, particularly in the buy-to-let market. The strong performance of lenders like Santander and the growth of smaller players suggest that there may be new opportunities for investment. Additionally, the shift in lender strategies, as evidenced by Barclays’ shrinking buy-to-let book, may indicate a broader trend of lenders reassessing their risk profiles and product offerings.
