Ingen is a privately owned Scottish business providing high-quality technical services.

Ingen was established in 2015, bringing together Lanarkshire-based Dalziel Services and Inverness-based Korrie Mechanical and Plumbing.

In February 2016, all of Dalziel’s activities moved under the Ingen brand. Korrie continues to operate as an independent subsidiary, covering the north and north-west of Scotland.

Ingen’s goal is to build a strong and successful business by delivering great service through great people.

Ingen is backed by Edwin James Holdings (EJH), a Glasgow-based company specialising in supporting the growth and development of privately owned businesses in the built-environment sector.

Ingen is owned by its employees, management and EJH.
