The list was published in the exchange’s third annual report of the fastest growing and most dynamic small and medium sized enterprises (SMEs) in the UK.
To be included in the list, companies needed to show consistent revenue growth over a minimum of three years, significantly outperforming industry competitors.
The Stourbridge-based group was founded 37 years ago and has grown rapidly over the last few years.
This has seen the firm expand into a range of manufacturing sectors from motorsport and transport industries to utilities and food and drink.
Chairman Jonathan Lee said: “I was delighted to hear that we had once again been included in the London Stock Exchange 1,000 Companies to Inspire Britain.
“Whilst we have benefited from a fairly buoyant engineering and manufacturing sector, our continued growth has been largely due to our diversification into a broader range of industries and services, such as our digital design office in Hatton, Warwickshire that supports manufacturing clients by providing pre-product concept work.
“Our flexibility, coupled with the hard work and continued customer focus of our 100-strong multi-talented recruitment and support teams results in 85% repeat business.”
