What Vredenburg Installatietechniek - Sinds 1922 does

Vredenburg Installatietechniek is a Dutch multi-discipline installation services company founded in 1922 in Steenwijk, Overijssel, and now operating as a business unit of ITBB Group following its July 2023 acquisition. The company designs, installs, and maintains electrical, plumbing, HVAC, solar PV, heat pump, security, fire detection, data network, EV charging, and zinc/copper roofing systems for residential, commercial, agricultural, and public-sector customers across the Steenwijkerland, Overijssel, Drenthe, and Flevoland regions.

Technically, the company's portfolio centers on integrated sustainable-building systems: 415 Wp photovoltaic installations (including multi-hundred-panel projects on commercial and farm roofs), air-source and ground-source heat pumps (with hybrid variants paired with HR boilers from ATAG, Intergas, and Stiebel Eltron), full HVAC including underfloor heating/cooling and WTW ventilation, LED lighting with Philips/Signify LED Expert status, smart thermostats (Nefit Easy), and building management systems. Compliance-driven capabilities include KIWA NCP fire detection certification, VEB security certification with VEB certificate issuance rights, DEKRA BRL 6000 audit approval, STEK F-gas certification, and InstallQ recognition, supported by a Solar-Specialist diploma holder on staff.

Vredenburg's revenue model combines one-time project-based installation work (quote-driven, materials plus labor) with recurring service and maintenance contracts covering heating, electrical, and solar systems, including 24/7 emergency response. Customers range from individual homeowners to enterprise accounts such as Dictator Emmeloord, Houthandel Wicherson, Eshuis Metaal, and Rendo Meppel, alongside agricultural farms and municipal/education clients. Approximately 50 employees operate from the Dolderweg 29 headquarters, which houses offices, a showroom, and warehouse, with mobile installation teams serving the broader region.
