Technisch Buro Zonderland B.V.

What Technisch Buro Zonderland B.V. does

Technisch Buro Zonderland B.V. is a privately held Dutch installation company founded in 1979 and headquartered in Minnertsga, Friesland. It operates as an allround total installer (totaalinstallateur) delivering heating, plumbing, electrical, and air-conditioning services to both private homeowners and business clients across the Friesland province. The service portfolio spans traditional installation work — central heating boilers, gas/water/sewage, electrical wiring and fuse boxes — alongside a growing sustainability offering that includes air-water and ground-source heat pumps, hybrid heat pumps, solar water heaters, water softeners, and EV charging stations. Bathroom and kitchen renovation is delivered as a complete project service, supported by 3D design visualization and a supplier showroom for sanitary fixtures.

The business model combines one-off installation projects (materials plus labor, billed per project), recurring maintenance subscriptions (ESF/TBZ Budget, Plus, and Totaal tiers with 18-month inspection cycles and tiered parts/labor coverage), and 24/7 emergency repair services billed hourly with minimum 60-minute increments. Distribution is fully direct-to-customer via phone, WhatsApp, email, and the company website, with the website also serving as a top-of-funnel marketing asset complemented by Facebook and LinkedIn presence and a strong word-of-mouth referral base. For larger construction projects the company acts as subcontractor to general contractors such as Bouwgroep Dijkstra Draisma, as demonstrated by the Gewoon De Beuk healthcare complex project. The company is certified under Techniek Nederland, InstallQ, Uw Duurzame Installateur, and VCA, with full ownership and daily management held by Arjen Plat since his 2022 takeover. Headcount is self-reported at 25+ employees, operating throughout Friesland on a 24/7 service basis for emergency calls.
