What Ohmegi does
Ohmegi Elektro AB is a Stockholm-headquartered electrical installation contractor founded in 1982, operating primarily across the Stockholm and Uppsala regions of Sweden as a wholly-owned subsidiary of Instalco, the Nordic installation conglomerate that operates 150+ subsidiaries and 6,000+ employees across Sweden, Norway, and Finland. The company delivers end-to-end solutions across four service lines: electrical installations (Elinstallationer) for new construction and renovation; service and maintenance (Elservice & underhåll); telecom, technology, and security systems including SBSC-approved intrusion and fire alarms and access control; and measurement collection (Mätinsamling/IMD) through a partnership with Infometric. Customer segments span construction companies and property developers (Skanska, NCC, Arcona, Betonmast/AF Gruppen, E.Novogruppen), public infrastructure and healthcare (Region Stockholm, Region Sörmland, Locum, SL/MTR, Jernhusen), and property owners seeking energy efficiency and individual metering solutions (housing associations, real estate firms).
The business operates a hybrid revenue model combining one-time project-based installations (contracts ranging from small jobs to total contracts valued at tens of millions of SEK) with recurring service and maintenance agreements under a 'total responsibility' (totalansvar) mandate. Sales are secured through competitive tendering and repeat enterprise relationships, with go-to-market anchored on direct engagement of general contractors and property developers. The company maintains certifications including ISO 9001, SBSC alarm class 2 approval, and material classifications under Byggvarubedömningen and Sunda Hus, and has held a Triple AAA credit rating (Bisnode) since 2008. It employs approximately 140 people (~120 installers in Stockholm, ~15 in Uppsala) and generated approximately 398 million SEK in revenue. Notable large-scale projects include Station Hagastaden (~90M SEK), Högdalen metro depot expansion (~150M SEK joint), Solna Link office (~68M SEK), Olivin / Skanska's new HQ (~50M SEK), Scandic Hotel Ariadne (~62M SEK joint), and the Södersjukhuset hospital modernization (~44.4M SEK).
