With this transaction, InstallerGroup Switzerland now encompasses five operational companies. With this acquisition, the total number of group companies in Denmark and Switzerland increases to 47.


Electro ERTI AG has been synonymous with reliable electrical services in the Bern region since its founding in 1994. Specialising in the B2B sector, the company serves a wide range of clients in property management, industry and commerce, as well as the public sector. In 2025, Electro ERTI AG generated an annual turnover of around 7 million Swiss francs and employs around 35 staff members.

Boris Bischoff, CEO of InstallerGroup Switzerland: 'With Electro ERTI AG, we are integrating an established company with a long-standing reputation for quality and reliability into our corporate group. At the same time, this group expansion marks the starting point of our expansion beyond the Zurich metropolitan area.'

The company will continue to operate under its existing name and will still be led by founder Ertugrul Kalmaz. He will be joined in the management team by Marc Schaller and Süleyman Memis, both of whom have been with the company for nearly two decades.

Ertugrul Kalmaz, founder of Electro ERTI AG: 'InstallerGroup appreciates the value of local entrepreneurship and provides us with a solid foundation for the next phase of our development.'

With the addition of Electro ERTI AG, InstallerGroup Switzerland is expanding its customer base and network in German-speaking Switzerland and securing additional competencies in the B2B realm of specialised electrical services - from planning through electrical installation to service and repairs.
