Weibel + Sommer Elektro Ag

What Weibel + Sommer Elektro Ag does

Weibel+Sommer Elektro AG is a Swiss electrical contracting and building-technology services company headquartered in Rothenburg (Canton of Lucerne), operating since 1989 as a subsidiary within the Frey+Cie Gruppe (16 group companies, 1000+ employees group-wide). It delivers electrical installations for residential, commercial, industrial, and infrastructure (e.g., highway) projects, supported by 24/7 emergency service and a service branch in Malters. Service lines include core electrical work, photovoltaic system design and installation, battery storage and E-Management (including ZEV self-consumption communities), building automation as a Loxone Gold Partner, E-Mobility charging infrastructure, and multimedia/WLAN installations. The company's technology stack combines in-house electrical expertise with third-party platforms — Loxone Miniserver for building automation, Solarmanager and E3DC Hauskraftwerk for PV and storage monitoring, and TeamViewer for remote support — under an ISO 9001 quality management system certified since 1997.

Revenue is generated primarily through project-based professional services and hardware-plus-installation contracts, with quote-based pricing on individual assessments. GTM is sales-led and field-based, centered on direct customer engagement, site visits, consultations, service contracts, and 24/7 emergency response across the Lucerne region. Customer segments span residential homeowners and developers (new builds and renovations), commercial/industrial businesses, and renewable-energy and e-mobility adopters; Swissolar 'Solarprofi' membership and Loxone Gold Partner status anchor the energy and automation verticals. Approximately 30-50 individuals staff the operation across Geschäftsleitung, Kader/Administration, Installateure, and Lernende, with active apprenticeship pipelines. Leadership transitioned to Fabian Renggli as Geschäftsleiter in 2025, following a 2024 relocation to ZESY Rothenburg and corporate identity refresh.

The company is privately held within the Frey+Cie Holding structure; co-owner Meinrad Sommer serves as Deputy Managing Director and Paul Weibel (CEO 1993-2022) remains on the Board. No external funding rounds, public financials, or app distribution channels are disclosed; distribution is exclusively direct field service within Central Switzerland.

Comparable through its Loxone-adjacent building automation, energy monitoring, and EV charging hardware ecosystems that Weibel+Sommer integrates, but operates as an upstream technology supplier rather than a competing installer.
• ABB E-mobility SpA: Swiss-headquartered EV charging hardware and infrastructure provider serving the same fleet and depot charging market Weibel+Sommer addresses at the installation level. Comparable on E-Mobility charging infrastructure but positioned upstream as a charger manufacturer rather than installer.

Regional players
