Research from Direct Line For Business claims almost one in four small businesses (24%) has been the victim of business crime in the past two years. The study of small business owners and sole traders, of which there are more than four and a half million in the UK, also revealed that the average insurance claim resulting from a business-crime was £2,500.
Many business owners reported that in addition to being targeted by criminals their businesses were also coming under pressure from fraudulent non-payment of bills.
One in eight (13%) of companies interviewed reported this in the survey making it a bigger threat than any single crime.
Vehicle break ins and thefts from the workplace were the most frequent crimes reported by small businesses with more than one in twenty (7%) companies falling victim to each.
Around 360,000 crimes or one third of the total crimes against business resulted in the company having to make an insurance claim amounting on average to £2,500 making the bill to insurers approximately £833m.
This would be split across trade credit insurers and business insurers, encompassing the likes of employer's liability insurance, commercial property and commercial vehicle insurance products.
Jazz Gakhal, head of Direct Line for Business, said: "It's alarming to see that as much as a quarter of small businesses have recently been affected by crime though unfortunately this is always likely to increase in an economic downturn.
"The research demonstrates the importance of sufficient protection of the business as claims typically average £2,500 and an unexpected bill of this size could put huge pressure on many small business owners. Businesses should explore the variety of insurance options available to ensure they have appropriate cover for all sectors of operations."
