Halg Group

What Halg Group does

Hälg Group is a Swiss family-owned provider of building services technology (Gebäudetechnik) and integrated facility management, founded in 1922 and now in its fourth generation of family ownership under the Baumer family. The group operates from approximately 30 sites across Switzerland, employs more than 1,000 people, and has publicly targeted 1,250 employees by the end of 2026. Its service portfolio spans HVAC and heating system construction (Anlagenbau), maintenance and service, ventilation hygiene cleaning (Lüftungsreinigung), building automation, and integrated facility management. Operating entities include Hälg & Co. AG, Hälg Facility Management AG (HFM), Klima AG, Dober AG, Zahn + Co. AG, Meneo Energie SA, GOAG, and the recently acquired Valcalorie SA. The group's reach is strictly domestic — Switzerland is its sole operating geography.

The business model combines long-term service and facility management contracts with project-based installation work. Recurring revenue is anchored in multi-year maintenance and FM agreements with healthcare, industrial, infrastructure, and public-sector customers, including named clients such as Swiss Life Arena, Kantonsspital, Hôpital Universitaire de Genève (HUG), IWB, Pilatus Aircraft, and Bell Food. Hälg Group holds ISO 9001, 14001, and 45001 certifications, is recognized as a suissetec Top Training company, and is certified as a Kununu Top Company — credentials that function as procurement gates in regulated Swiss end markets. The current portfolio tilt toward heat pumps, energy-efficient retrofits, and IoT-enabled building automation is positioned to capture Switzerland's decarbonization-driven demand cycle.

Strategically, Hälg Group is executing an active M&A program, completing eight or more acquisitions between 2024 and 2025 (Meier Tobler, Caspar, Oberhännsli, Löwen, Charly Sanitaire, Dörflinger, Valcalorie, Wintsch) to expand service-line breadth and geographic coverage, with a particular push into French-speaking Switzerland via the Valcalorie SA deal. In 2024, governance was professionalized with the appointment of Sandro Keller as CEO of the Building Technology division, marking a transition from family-led to family-owned/professionally managed operations. Revenue is not publicly disclosed, consistent with the group's private, family-owned status.

Direct peers

• ENGIE Services AG (Switzerland): Swiss arm of ENGIE delivering HVAC, energy, building automation, and integrated facility management to enterprise and public-sector customers. Directly comparable in service portfolio, multi-branch coverage, and vertical specialisation in healthcare and infrastructure.
• Bouygues Energies & Services Schweiz AG: Swiss subsidiary of Bouygues providing multi-technical building services, energy solutions, and facility management with national coverage. Closely comparable scope across HVAC, sanitary, building automation, and FM for enterprise customers.
• ISS Facility Services AG: Global integrated facility services provider with strong Swiss presence in Zürich, Bern, and Geneva. Comparable in multi-site FM contracts, 24/7 Help Desk operations, and integrated technical/infrastructural/commercial FM delivery.
• Meier Tobler Group AG: Swiss HVAC and building services distributor/installer offering heating, cooling, ventilation, and sanitary solutions. Comparable product portfolio, especially in residential heating replacement and ventilation hygiene (the segment from which Hälg acquired Meier Tobler's air-hygiene unit in 2024).
• Sauter AG (Fr. Sauter AG): Swiss building automation and HVAC controls specialist headquartered in Basel. Directly comparable in building automation, room automation, HVAC regulation, and energy-monitoring services delivered to Swiss enterprise customers.
• Equans Switzerland (formerly ENGIE Refrigeration / Axima): Multi-technical building services and energy solutions provider active in Switzerland, with comparable HVAC, refrigeration, and integrated FM capabilities. Carves out from ENGIE in 2022 and now operates as a separate European multi-tech platform competing in the same Swiss tenders.

Broad incumbents

• Siemens Smart Infrastructure (Switzerland): Global building technologies and digital infrastructure provider with a Swiss operation. Overlaps with Hälg's Gebäudeautomation and energy-monitoring offering but as part of a much broader portfolio; serves as both partner and competitor for large-scale smart-building tenders.

Emerging players

• Belimo Automation AG: Swiss-headquartered global market leader in HVAC actuator and valve technology. Hälg is an installation partner on earthquake-safe ventilation projects for Belimo; Belimo is an adjacent/complementary player rather than a direct service competitor but overlaps in smart-building technology.
• Helbling Group: Swiss engineering and technical services group with building-services and FM-adjacent capabilities. Comparable as a mid-sized Swiss family-influenced technical services firm, though smaller and less building-technology-focused than Hälg.

Others

• Implenia AG: Switzerland's largest construction and real-estate services group. While Implenia is a general contractor rather than a building-services specialist, it is a frequent project partner and benchmark for the Swiss construction cycle that drives Hälg's Anlagenbau backlog.
