An industrial agricultural business trades alongside the main road in Leeming Bar.
John H Gill & Son have been in the village since 1937 when they bought out the foundry of F Mattison & Co. Run by William Mattison, the company made much agricultural machinery at their foundry which was built on railway land at Leeming Bar.
However, the company was known mostly for its cast-iron mileposts, of which about 100 survive across North Yorkshire.

Leeming Bar is host to an industrial estate that houses, among other things, the headquarters of Froneri, who make Fab and Rowntree's Fruit Pastilles ice lollies.
A household waste recycling site is also on the industrial estate.

The Vale of Mowbray food factory is also in the village.
The factory has suffered two fires in the 21st century; in 2002 a major fire caused an industrial oven to explode and led to the company being prosecuted by the Health and Safety Executive.
In 2017, another fire led to 10,000 smoke damaged pork pies being destroyed by the company.
