Profits may have fallen 17 per cent - but military truck supplier L. Jackson is still top of the table in Doncaster.
The firm, based in Misson, near Bawtry, made £3.7m profit last year, down from £4.48m the year previous.
As well as topping its local table, it climbed to fourth in the main Top100 which ranks firms by profitability. Companies House figures show it made the sum on £9.9m turnover and just eight employees.
L.Jackson is one of the world’s biggest suppliers of ex-military trucks, vehicles, plant and equipment. Its 60-acre site near Doncaster Airport is home to about 1,000 vehicles which are fixed up by an army of contractors and sold off to organisations around the world.
Paragon Property Investments is second on the list - and a newcomer this year. It made £2.13m, a 66 per cent rise on the year before.
Direct Trade (Yorkshire) is fourth on the Doncaster table after a 65 per cent increase in profits. It was good enough to catapult it from 79th in the main list to 37th this year - an impressive climb.
The firm, based on Sandall Carr Road is a nationwide manufacturer of uPVC windows, doors and conservatories. Established in 1988, it now operates from three factories, one each for windows, doors and conservatories.
Go Green, of Parrots Corner, is a newcomer at number five and straight in at 42 on the main table, with £1.67m pre-tax profits.
As a wastemanagement broker, it offers customers access to more than 1,000 facilities across the country.
The company can trace its roots back to a family business set up by the Bolland family in 1968. It grew rapidly after gaining the waste disposal contract for the new M18 and developed a transfer station for the segregation of waste. Go Green was formed in 2000 to develop a network of suppliers offering a similar service.
Turbine Efficiency Group is an up-and-coming newcomer to the SME list this year, posting a very impressive 933 per cent rise in profits.
The firm, based on Hayfield Business Park, Finningley, specialises in the maintenance, overhaul and servicing of gas turbines.
