De Leeuw Installaties

What De Leeuw Installaties does

De Leeuw Installaties B.V. is a Dutch installation company headquartered in Rijssen, Netherlands, founded in 1978 and operating as part of the Van Dam Groep, a diversified installation conglomerate. The company delivers complete heating, plumbing, electrical, climate-control, ventilation, and sanitary installation services (W and E) for both new-build and renovation projects, with a production capacity of 300-400 residential units delivered annually. Its primary customer base consists of Dutch construction firms and real estate developers (including Bouwbedrijf Roosdom Tijhuis, Lichtenberg Exclusieve Villabouw, Ter Steege Bouw Vastgoed, Baalderborg Groep, and Bouwbedrijf Homan) on the B2B side, and individual homeowners on the B2C side, with a focus on the luxury residential segment and care/utility buildings.

The company's core technology centers on conventional Dutch building-services engineering rather than proprietary platforms: it specifies, supplies, and installs third-party equipment such as Intergas HRE A combi boilers (CW3/CW4/CW5), Daikin Altherma heat pumps, hybrid heat-pump/CV systems, solar panels, Zehnder Q450 WTW heat-recovery ventilation, and branded sanitary ware (Villeroy & Boch, Grohe, Cleopatra). It has invested in workshop-based prefab capabilities to pre-cut and pre-assemble components such as ventilation ducts, reducing on-site assembly time and waste. The firm holds the full suite of mandatory Dutch installation certifications (BRL 6000 parts 1/2/4/7/8, BRL 6000-21 for ground energy systems, BRL 6000-25 for gas combustion appliances, BRL 100 F-gassen, VCA*, CO-vrij, STEK, InstallQ) and is accredited as an "Erkend leerbedrijf" training company.

Revenue is generated through three streams: project-based installation contracts with construction companies (priced per project via tendering), direct-to-consumer installation sales to homeowners, and recurring 24/7 service and maintenance subscriptions. Pricing is quote-based with no public disclosure; the company actively markets ISDE government subsidies of €1,000-€2,500 and Energiebespaarlening financing to stimulate sustainable-energy demand. The go-to-market is hybrid enterprise field sales for B2B and direct-to-consumer for residential, supported by a website, Facebook, and Instagram presence with phone-driven lead capture. Geographic reach is single-country (Netherlands), covering Twente, Overijssel, Drenthe, North Holland, and Utrecht.
