UK Finance’s latest buy-to-let mortgage market Update for Q1 2026 showed that there were 58,272 new buy-to-let loans advanced in the UK, worth £10.8 billion. This was up 3.26 per cent by number compared with the same quarter in the previous year, 7.02 per cent by value.
The average gross buy-to-let rental yield for the UK in Q1 2026 was 7.21 per cent, compared with 6.93 per cent in the same quarter a year previously.
The number of BTL fixed rate mortgages outstanding in Q1 2026 was 1.47 million, 1.4 per cent up on a year previously. In contrast, the number of variable rate loans outstanding fell by a further 9.5 per cent to 453,000. The average interest rate across all new buy-to-let loans in the UK was 4.71 per cent in Q1 2026.

Reflecting the downwards movement in interest rates, the average buy-to-let interest cover ratio (ICR) for the UK in Q1 2026 was 221 per cent, up from 204 per cent in Q1 2025 and 218 per cent in the previous quarter.
At the end of Q1 2026, there were 8,960 buy-to-let mortgages in arrears greater than 2.5 per cent of the outstanding balance. This was down 560 from the previous quarter. There were 810 buy-to-let mortgage possessions taken in Q1 2026, unchanged from the same quarter a year previously.
Louisa Sedgwick, Managing Director of Mortgages at Paragon Bank, said “Although buy-to-let lending moderated from the stronger levels seen at the end of 2025, activity in the first quarter remained ahead of the same period last year, indicating that the market continues to move in the right direction where conditions are supportive.
“Remortgaging remained a significant driver of lending and was higher than a year earlier. This points to landlords actively refinancing as they respond to broader affordability considerations and manage their portfolios, including supporting longer-term plans such as expansion and investment in existing properties.
“The value of outstanding balances also rose above £313 billion, underlining the resilience of the sector and its continuing role in supporting investment in privately rented homes.
