Company ‘reacted swiftly during swap rate volatility’, says CEO

Buy-to-let has continued to drive success for the UK’s latest independent specialist buy-to-let lender OSB Group in its second-half results, with BTL accounting for 68% of its total loan book in the period – the same proportion as in its full year 2025.

OSB Group includes OneSavings Bank (OSB), which originates mortgages via specialist brokers and independent financial advisers through Rely and InterBay Commerical, and Charter Court Financial Services (CCFS) which provides specialist residential mortgages and short-term bridging and operates Precise and Charter Savings Bank.

OSB’s Kent Reliance for Intermediaries (KRFI) buy-to-let mortgages and CCFS’ Kent Reliance for Intermediaries Residential mortgages were both withdrawn by the group towards the end of 2025 as part of a strategy to simplify its brand portfolio.

Rely serving all new BTL borrowers

Instead, Rely, which launched last November, now serves all of the group’s new Buy-to-Let borrowers. Refinancing accounted for 75% of Rely and Kent Reliance buy-to-let completions under the OSB brand in the period. New borrowers, meanwhile, continued to favour five-year fixed rate mortgages, which accounted for 78% of completions, the company said.

Group CEO Andy Golding, who will retire at the end of the month, said the company performed well despite the disruption caused by the Middle East conflict. “We were able to react swiftly during the period of swap rate volatility, protecting our margins and originating high-quality Buy-to-Let business as our competitors withdrew their products,” he said.

Within residential, the group soft-launched residential lending on a new platform with a small group of brokers in the first half and will do a full market launch later this year after assessing broker feedback to improve functionality.
