What InstallatørGruppen does

InstallatørGruppen is a Denmark-headquartered technical installation group operating 47 decentralized subsidiary companies across Denmark and Switzerland. Founded in early 2023 through 11 initial acquisitions and sponsored by FSN Capital VI, the group offers multi-disciplinary installation services spanning plumbing and heating, electrical systems, ventilation, refrigeration and cooling, and specialist areas including sprinkler systems, building automation (CTS-anlæg), solar panel installations, energy optimization, and fiber and copper cable infrastructure. The group is publicly listed on Nasdaq Copenhagen following an IPO completed on June 11, 2026, at a DKK 15 per-share offer price and an approximate DKK 4.5 billion market capitalization, with FSN Capital VI retaining approximately 46.7% of shares post-listing.

The business model is a roll-up of fragmented local technical installation firms, where each acquired company retains its name, brand, management team, and customer relationships while gaining access to group-level capital, procurement, M&A capability, and ESG/sustainability infrastructure. Revenue is generated through project-based new installations, renovation work, and recurring service and maintenance contracts delivered to residential customers, commercial real estate, industrial facilities, healthcare institutions, and public-sector buildings. Combined 2025 revenue reached DKK 4.2 billion with adjusted EBITA of DKK 410 million (approximately 9.8% margin), up from DKK 1.4 billion reported at founding.

The group targets fragmented European technical installation markets through continued bolt-on M&A, having completed more than 45 acquisitions since establishment, with a third European market entry guided for 2027. Its SBTi-validated climate targets (42% Scope 1&2 reduction by 2030, net-zero by 2050) and a dedicated Spectia ESG data platform position it for green-transition project pipelines. Go-to-market is sales-led via each subsidiary's direct local customer relationships, with no disclosed digital customer acquisition channels and pricing set on individualized B2B project and service contract terms.

Direct peers

• Caverion: Finnish building solutions and MEP services company serving the Nordics and Central Europe with installation, maintenance, and energy-retrofit services; direct competitor for energy-transition projects.
• Bravida: Largest Nordic multi-technical services provider (electrical, heating & plumbing, ventilation, security, sprinklers); a more mature Nordic rollup listed on Nasdaq Stockholm and the most relevant scale benchmark.
• Instalco: Swedish MEP services rollup operating a near-identical decentralized model of acquired local installation companies across Sweden, Norway, Finland, and Germany; the closest model and geographic comparable for InstallatørGruppen.

Broad incumbents

• ENGIE: Global energy and multi-technical services conglomerate with significant HVAC, electrical, and energy-transition service operations in Europe; relevant for energy-transition positioning though not a direct rollup comparable.
• Vinci Energies: Vinci division offering multi-technical services (electrical, HVAC, information systems, facility management) across Europe; broad incumbent competitor in the European MEP and energy-transition services space.
• Equans: Bouygues-owned multi-technical services group providing HVAC, electrical, and facility management across Europe; relevant as a much larger incumbent competing for similar commercial and industrial MEP contracts.
• SPIE SA: Paris-listed European multi-technical services group providing electrical, mechanical, HVAC, and energy services across 30+ countries; broader scope and larger scale than InstallatørGruppen but the most relevant European listed incumbent.
