What Willemsen Installatie does
Willemsen Installatie is a Dutch technical installation company founded in 1935 in Heino, Salland, and operating today as part of Nijhof Groep - a family-held group of four specialized installation firms (Nijhof Installatietechniek, Willemsen Installatie, Eefting Installatie, and Salland Installatieservice). The company positions itself as a totaalinstallateur (total installer) delivering end-to-end electrical, HVAC, plumbing, ventilation, and climate-control installations for the commercial utility market and large-scale serial renovations. Core technical capabilities include W-installatie (electrical systems), climate and ventilation systems, heat pumps (e.g., a 28-source, ~200 m deep ground-source system at the Jarola distribution center), VRF systems, and underfloor heating for projects ranging from 12,000 m2 production halls (Pan Oston) to 15,000 m2 distribution centers (Jarola). A distinguishing capability is the Duurzaamheid Inspiratie Centrum in Broekland, which develops energy-efficient and circular building techniques used across the group's projects.
The company makes money through project-based, custom-quoted B2B contracts (multi-year cadence) with no public pricing tiers; revenue is generated per engagement rather than via recurring subscriptions. Its go-to-market is sales-led and direct, targeting commercial real estate, manufacturing, distribution, and housing-corporation clients primarily in the Salland/Overijssel region, with demonstrated project delivery extending to Nijmegen, Coevorden, and Haaksbergen. Workforce development is a strategic pillar: the in-group Salland Tech Academy trains ~20 students per year, supplemented by BBL pathways through Deltion College and partnerships with ROC Aventus, Carmel College Salland, and InstallatieWerk (IW). Ownership remains within the Nijhof family (Angelique Nijhof as group director), with no external funding, public listing, or disclosed revenue figures; growth relies on regional reputation, group-level resource sharing, and talent pipeline rather than capital expansion.
