Semi-commercial mortgage lending rose by 20% to around £242m in the second quarter of this year, up from £201m in the same period of 2025, new figures from TAB suggest. In its new monthly index of mixed-use mortgages, the lender estimates market-wide volumes based on its own data and other publicly-available numbers. It says transaction volumes increased by 13% year on year, from approximately 415 completions in Q2 2025 to 470 in Q2 2026. TAB says it is seeing mainstream banks step back from smaller and more complex deals, which is creating opportunities for specialists. “Mainstream high-street banks scaled back complex commercial lending significantly after 2008, creating space for a wave of challenger banks and specialist lenders that has continued to expand ever since.
