Specialist motor manufacturer Allied Vehicles saw its pre-tax profits more than double from £1.85 million to £4.03m in the year to April as turnover rose 19 percent from £89 to £106m.

According to a Companies House filing, the company based in Glasgow’s Possilpark, saw earnings before interest, tax and depreciation rising 75 per cent to £5.1m.

The company, which sells and repairs vehicles for people with impaired mobility, said that it had expanded its export activity to include all major European countries and is now negotiating the supply of conversion kits to Central America.

“Our share of the UK motability market remained above 40 per cent but we also expanded private hire car sales and converted patient transport ambulances,” the company said in its strategic report for the year.

“Rentals, parts, bodyshop, defleet, mobility shop and service departments performed strongly during the year and we anticipate that this will continue.”

Allied Vehicles also highlighted that it had received funding from Scottish Enterprise to support a £2.5m programme of research and development of new products.

“This will help us to ensure that we have a team capable of generating world-class products that the company can bring to market,” the company said.

Its order bank is growing despite increased production, it said, and further growth is expected this year. "We feel that all the constituents are there for Allied Vehicles to improve on this excellent performance in "2015-16".

The company’s increased profits came in spite of a rise in administrative costs from £14.6m to £16.9m and the cost of sales growing £73.2m to £85.5m.

Directors’ pay doubled from £622,431 to £1.29m with the highest paid director being paid £728,828, up from £131,683 the year before. Directors’ pension costs rose from £82,307 to £133,522.

After paying no dividend the previous year, the company paid a dividend of £7.76 per share which amounted to total dividend payments of £440,000.
