Simm, our story

Established in 1941 as GE Simm (Surplus in Modern Machinery) Ltd, Simm Engineering Group began as a company supplying second-hand machinery and valves, conveyor belting, hydraulic mining equipment and air compressors.

Growth and acquisitions

Based in Sheffield since its inception in 1941, Simm Engineering Group has made several acquisitions over the years.

Most notable for the compressor division was the purchase of Compressor Maintenance Ltd in 1979, which significantly expanded the order book with large contracts with customers such as Tetley Brewery.

In March 2015, the compressor division was acquired by Pennine Pneumatic Services (PPS), heralding a new era of expansion.

The next addition came in June 2019 when Airtight Compressor Services was acquired to become part of Simm Engineering Group. This brought together two well known Sheffield air houses, with the experienced Paul Woodhouse joining the South Yorkshire team.

The Summer of 2020 brought transformational change as the company moved to new premises in Dinnington, Sheffield. Having been at the previous Jessell Street base since 1963, Simm Engineering Group had massively outgrown the unit, and were in need of more workshop and office space for their growing team, stock and customer base.

Energy-saving solutions

Today the company focuses on providing energy-saving turnkey solutions to customers across South Yorkshire and beyond.

Its dedicated team of highly experienced engineers provide expert advice, speedy trouble-shooting and ongoing preventative maintenance to keep production running at optimum levels. There’s also an onsite Sales Counter open to the public, with a wide range of spares and parts in stock or available to order.
