Small business borrowing surges 63% in Q2 2026 amid rising costs and cashflow uncertainty
New data from Purbeck Insurance Services, the UK’s only provider of personal guarantee insurance for SME owners, reveals that applications for personal guarantee-backed finance rose 63% year-on-year in Q2 2026, reflecting sustained and growing demand for borrowing among small and medium-sized businesses. Behind every loan application is a director who has personally guaranteed a business loan and the scale of that exposure is growing as Purbeck’s data shows the average loan value exceeded £300,000 for the second consecutive quarter.

Working capital crisis driving borrowing surge
Working capital — the day-to-day funding needed to keep a business trading — remains the single biggest driver of personal guarantee-backed borrowing, accounting for 36.2% of all Q2 2026 applications and the volume of working capital loans has almost doubled in just two years. The trend points directly to the cashflow pressure bearing down on UK SMEs: 40% of trading businesses reported rising input costs in April 2026 — the highest proportion since December 2022, according to the ONS Business Insights and Conditions Surveyi.
The picture is not, however, one of businesses simply firefighting. Finance for investment in growth initiatives accounted for 20% of all applications — the second most common reason for borrowing. Businesses are also seeking finance for asset purchase, development and acquisition, which together account for nearly one in four of all applications. The breadth of borrowing purposes suggests that SME owners are balancing short-term cashflow pressures with continued longer-term investment, even in a difficult environment.
The start-ups overtake established businesses
New businesses are borrowing more on average than established ones with the average start-up loan reaching £345,000, backed by a personal guarantee. Established businesses bring track records, customer bases and assets that give lenders confidence. Start-ups have none of these. A director taking on £345,000 of personally guaranteed debt at the earliest and most vulnerable stage of building a business is carrying an extraordinary level of risk.
Todd Davison, managing director of Purbeck Insurance Services, said: “The near-doubling of working capital applications over two years confirms many business owners are borrowing to survive rather than to grow. That pressure is compounded by a policy environment that has given SMEs little certainty — a change of prime minister, and now the prospect of significant structural change. Whatever the merits, the practical effect for a business owner trying to plan ahead is uncertainty, and uncertainty is the enemy of confident investment.
“What concerns me most in this quarter’s data is what’s happening at the start-up end of the market. For the first time in a year, new businesses (under 2 years old) are taking on higher average loans than established ones. These are directors putting their homes on the line before they’ve had a chance to build a track record, a customer base, or any meaningful financial cushion. That is a significant personal risk to carry at the earliest and most vulnerable stage of building a business.
“With the average loan value remaining above £300,000, the personal financial risk carried by small business owners when providing a personal guarantee to a lender should not be underestimated.”
