Hjarsø El-teknik ApS becomes part of InstallatørGruppen

IGPress release12.11.2026 klo 09.31

InstallatørGruppen has entered into an agreement to acquire Hjarsø El-teknik ApS, an electrical installation company based in Greve, Denmark, serving private and commercial customers in the Greater Copenhagen area. The acquisition marks InstallatørGruppen's 44th acquisition in Denmark, bringing the total number of companies across Denmark and Switzerland to 50.

Including one previously announced transaction in Denmark, which is pending regulatory approval, the total number of acquisitions in Denmark will be 45, and the total number of companies across Denmark and Switzerland will increase to 51.

Hjarsø El-teknik was founded by Christian Hjarsø in 2016 and has since grown into a modern, service-oriented electrical contractor with 18 employees. The company carries out all types of electrical work, from service, electrical inspections and switchboard replacement to renovation and energy optimisation. In addition, Hjarsø El-teknik works with solar panels, EV charging stations, smart installations, AI and CTS.

The acquisition strengthens InstallatørGruppen's position within electrical installation in the western part of Copenhagen and the Greater Copenhagen area and adds a well-functioning service business with high customer satisfaction to the Group.

Hjarsø El-teknik will continue as an independently run company under its current management, consisting of Christian Hjarsø, in line with InstallatørGruppen's decentralised partnership model.

Peter Frandsen, Country CEO of InstallatørGruppen in Denmark, comments: “Christian Hjarsø has built a modern and well-run electrical company with a strong focus on service and quality – and that is something the customers notice. This is exactly the kind of professional pride and local roots we value in our companies. We look forward to welcoming Christian and his employees to the Group.”

Christian Hjarsø, Owner-Manager of Hjarsø El-teknik, says: “I have built Hjarsø El-teknik on quality craftsmanship and good service, delivered on time and at the agreed price. As part of InstallatørGruppen, we can continue to run the company on our own terms, while benefiting from a strong community and valuable sparring that can take us to the next level. It has been crucial to me that both our culture and our employees can remain as they are.”
