Immens

What Immens does

Immens Installatietechniek BV is a Dutch mechanical installation services firm headquartered in Sint-Michielsgestel, North Brabant, founded in 1822 as a blacksmith shop and now operating as a subsidiary of De Groot Installatiegroep following a January 2022 acquisition. The company designs, installs, and maintains HVAC, sanitary, ventilation, and sustainable energy systems for both residential homeowners and commercial customers across the Netherlands, with particular specialization in WKO (Warmte-Koude-Opslag) ground-source heat and cold storage systems, heat pumps, solar panels, and high-efficiency central heating boilers. Its commercial portfolio spans healthcare (Cello, Amarant, Mijzo), financial services (Rabobank), retail (Jumbo), technology (ASML), education (Gymnasium Beekvliet, KPO schools), municipal government (Gemeente Deurne), and housing associations (Brabant Wonen), with marquee reference projects including a gas-free municipal building retrofit with WKO installation and Rabobank's first sustainable regional office.

The business operates through four revenue streams: project-based installation contracts for commercial clients (one-time), tiered residential maintenance subscriptions (Basis, Comfort, and All-In tiers priced from €8.05 to €16.20 per month), 24/7 emergency repair services with zone-based travel charges, and managed remote-monitoring services delivered through the proprietary Installatie Beheer Systeem (IBS) platform. Go-to-market is direct field sales and service-delivery rather than channel-based; the company employs roughly 50-55 professionals across project, retail, residential, and service & maintenance departments. Certifications include ISO9001, VCA**, Kiwa (BRL K25000), InstallQ (BRL 6000-21/00), F-Gassen, and CO-vrij — the last being mandatory under the Dutch Gasketelwet that took effect April 1, 2023 and restricts gas-boiler work to certified installers. The company is a member of industry associations NVKL and Techniek Nederland, and continues to operate under the Immens brand within the De Groot Installatiegroep group structure.

Direct peers

• Unica: Major Dutch multi-disciplinary installer covering HVAC, plumbing, electrical and building management for commercial and residential clients; comparable in offering set but materially larger scale.

• Verhoef Duurzaam Installatiebedrijf: Dutch sustainable installer with WKO, heat-pump and solar specialization; comparable niche focus on sustainable climate systems in the same Dutch regional market.
• Kropman Installatietechniek: Dutch MEP/HVAC contractor focused on sustainable installations, building services and maintenance contracts for institutional and commercial customers; directly comparable specialty trade model.
• De Groot Installatiegroep: Acquired Immens in January 2022; operates multiple Dutch installation subsidiaries delivering HVAC, electrical and sanitary solutions to identical residential and commercial customers. Closest comparable given overlapping services, geography and ownership.
• HOMIJ Technische Installaties: Dutch HVAC and building-services contractor serving commercial, healthcare and utility clients with WKO, heating and climate-control installations. Comparable in scope and regional/NL footprint.
• Feenstra Verwarming: Established Dutch heating/cooling installer focused heavily on residential service, maintenance subscriptions and boiler replacements; most comparable subscription-side business model.

Broad incumbents

• Croonwolter&dros: Large Dutch technical services group providing HVAC, electrical, fire safety and automation across commercial, industrial and infrastructure markets; broader portfolio but directly overlapping on HVAC project work.

Others

Emerging players

• Eteck: Specialized Dutch heat-pump and sustainable-energy installation provider; narrower product focus than Immens but operates in the same service geography and customer economics around the energy transition.
