What Loohuis does
Loohuis Installatiegroep B.V. is a third-generation, family-owned Dutch total installation group headquartered in Fleringen, Netherlands, founded in 1953 by Bernard Loohuis. The group operates through approximately 17-18 subsidiary companies across 13+ regional offices in Eastern Netherlands (Twente, Salland) plus a German operation (Loohuis Installationstechnik GmbH, Rheine, est. 1996), with more than 650 employees. It functions as a totaalinstallateur (total installer) providing end-to-end technical building services for residential, commercial, utility, retail, and industrial customers, including housing corporations and enterprises such as Vivochem, Solidiam, Asito, Monuta, and ROC van Twente.
The group's offering spans electrical, HVAC, climate control, plumbing, sanitary, ventilation, smart home/domotica (KNX, DALI, VRF), security (fire, intrusion, CCTV, access control via Meulenbeld Beveiliging, BORG-E certified), and sustainable energy (heat pumps, solar panels, EV charging, batteries, energy management via Loohuis Energie using brands such as Solis, SolarEdge, Sigenergy, Pylon). A distinctive offering is Loohuis Modulair, a 2024-launched B.V. producing prefabricated mass timber modular housing with integrated smart-home QR-code documentation, winner of the Nationale Houtbouwprijs 2022. Technical capabilities include certified ground-source heat pump design (BRL6000-21), brine heat pump networks, PVT solutions, BREEAM-certified installations, and a prefab hall in Almelo for off-site module assembly.
The business model combines project-based professional services installation work with recurring service/maintenance contracts through Loohuis Service (split into Woonbeheer for housing corporations/VvEs and Technisch Beheer for utilities/industry/retail/inspections), plus hardware sales of energy systems. GTM is exclusively direct enterprise/field sales through the regional office network, with no resale or e-commerce channels. Pricing is quote-based per project, not publicly disclosed. Revenue is not publicly disclosed; the firm has pursued consistent bolt-on M&A growth (Elders 2011, Schulte 2021, Schutte 2023, Installround 2024, Jansen 2025, Lammertink 2026) alongside new subsidiary creation.

- Van Dorp: Dutch family-owned technical service provider offering HVAC, electrical, plumbing, and facility maintenance across commercial, industrial, and residential segments. Comparable total installer / service contract model with recurring maintenance revenue.
- Kuijpers: Dutch family-owned technical installer focused on HVAC, electrical, plumbing, and sustainable building solutions for commercial and industrial clients. Closely comparable in mission, ownership structure, and service breadth, operating across the southern Netherlands.
- HOMIJ: Dutch technical installation firm specializing in electrical, mechanical, and building services for utility, data centers, healthcare, and commercial buildings. Comparable multi-discipline installer profile with similar B2B project orientation.
- Croonwolter&dros: Major Dutch technical services and installation contractor covering electrical, mechanical, HVAC, and building automation for utilities, industry, and buildings. Comparable total-installer scope but with a much larger national footprint.

- Koninklijke BAM Groep: Major Dutch construction and engineering group with significant technical installation capabilities through BAM Bouw en Techniek. Comparable in technical installations and modular/modern construction methods but operates at vastly greater scale and geographic reach.
