A software provider to the motor finance industry is eyeing a stock market float that is expected to value it at more than £800m, making it the biggest technology listing for two years and putting its founder in line for a huge windfall.

Alfa Financial Software, which focuses on the $5.4 trillion asset finance industry, plans to float on the premium segment of the London Stock Exchange next month.

It comes amid a dearth of flotations in London since last year’s Brexit vote, and will mark the biggest listing by a tech business in the UK since Sophos, the cyber security group, made its £1bn market debut in June 2015.

Alfa counts Barclays, Mercedes-Benz and Bank of America as customers, supplying firms with software used to manage loans to finance the purchase of anything from office equipment to cars, planes and satellites.

Its initial public offering (IPO) is likely to draw attention because there are increasing fears that the rapidly growing UK and US motor finance industries are a bubble that is poised to burst.

Last month, the Financial Conduct Authority launched an investigation into British car financing, fuelling speculation products, in particular personal contract purchases (PCPs), may have been mis-sold or mis-valued. PCP leases have overtaken car loans and hire purchase as the most popular method of acquiring a car.
