The Story Behind the Company

TG Engineering was formed in 2002 by bringing two existing companies together that predominantly served the aerospace sector and its ability to supply and serve these existing aerospace companies has been built on and is still the case today. In 2007, Enco Engineering was incorporated into TG which was a highly regarded supplier in the scientific and semi-conductor sector and these sectors are still served today. NTE became part of TG in 2012 and continues to offer specialist vacuum chamber products. TG has consistently provided enhanced solutions for customers, such as assembly and supply chain management.

Employee Ownership Structure

In March 2018, an Employee Ownership Trust (EOT) was established which resulted in management and employees holding 30% of the shares in the company. The balance of the 70% shareholding is held by the exiting owners and Capital for Colleagues. As the loans from the external investors are paid off over the next three years, it is anticipated that the directors and employees will own 50% of the shares. This could rise even further thereafter, provided the company hits certain performance targets.

TG Engineering is a member of the Employee Ownership Association.

C4C’s Role

In March 2018, C4C invested £600,000 in TG Engineering by way of a secured loan. This investment entitled C4C to 35% of the equity, alongside the exiting owners, management and employees who own the remaining 65%.

Besides making this capital investment, C4C and partners from its agent Castlefield, are working closely with management and employees to help develop the employee ownership culture in the company. This is focussed on day to day and longer term active engagement activities, the meaningful sharing of information and in particular the financial performance of the company.

Castlefield is also providing company secretarial services, as well as helping to design and implement a Share Inventive Plan (SIP) scheme to give employees the opportunity to directly own shares in TG Engineering.



Whilst TG Engineering only introduced employee ownership in March 2018, The management have led the company through a detailed, engaging exercise to develop the vision, purpose, values and annual business plan and all employees are involved in monthly “all hands” meetings to discuss business performance. This has been well received and it complements the evident pride and craftmanship that is displayed by all.
