Who are we?

Key-Tech International Group’s subsidiary NEL Technologies Limited is a manufacturer of flexible heater assemblies and started out in 1984 in Consett before relocating to Newcastle, where its product development and innovation has led to enlisting global blue-chip companies as clients. NEL, which sees the majority of sales going to export markets, has become an EOT as it preserves the independence of the group and protects employment in the North East of England.

In January 2022 we transitioned from an owner managed business to a fully Employee Owned Business.

We are working together as equals to improve business efficiency and transparency across the organisation.

We are continuing to develop our very strong customer relationships to grow the business together for the benefit of our employees and customers.

We are tapping into support from the Employee Ownership Trust with training and awareness and participation at the Annual EO conference to assist on our journey.
