GK Elektro Lillehammer AS

What GK Elektro Lillehammer AS does

GK Gruppen AS (of which GK Elektro Lillehammer AS is a wholly-owned local subsidiary) is a family-owned Scandinavian technical building services contractor established in 1964 by the Karlsen family and now in its second and third generation of ownership. The group delivers integrated technical services across five disciplines — ventilation, electrical, plumbing, refrigeration/heat pumps, and building automation — spanning the full building lifecycle from consulting and design through installation to ongoing operation and service. Customers include hospitals, museums, universities, data centres, airports, hotels, defence installations, and private homeowners across Norway, Sweden, and (until January 2026) Denmark.

The company operates both enterprise field sales to institutional clients and a network of local offices serving Norwegian homeowners for residential electrical and plumbing work. Revenue is generated through three streams: large one-time technical installation projects, recurring service and maintenance contracts (including the GK Cloud smart digital operations support platform that provides continuous remote monitoring and analytics), and shorter-cycle consulting/design services. The order reserve stood at NOK 2,422 million as of 30 September 2025, with 9-month 2025 revenue of NOK 4,746 million and Q1 2026 quarterly revenue of approximately NOK 1.5 billion.

GK's technology stack centres on building automation and its GK Cloud platform, which monitors HVAC, lighting, and energy systems in real time and applies optimization logic that has produced a SINTEF-validated 33% energy reduction in older buildings. The company holds ISO 9001 and ISO 14001 certifications, is a member of RENAS and Grønt Punkt, and has had its short-term climate targets verified by the Science Based Targets initiative. Notable contracts in 2025 include framework agreements with Forsvarsbygg (NOK 600 million potential) and the University of Bergen (NOK 80 million over 8 years), the Vikingtidsmuseet rehabilitation (NOK 48 million), the Himmeltind radar facility (NOK 100 million+), and the Solsiden care centre in Mo i Rana (NOK 161 million). In January 2026 the group sold its Danish service operations to Caverion and is refocusing on Norway and Sweden.
