What Gebr. Kok Installatietechniek does

Gebr. Kok Installatietechniek is a Dutch family-owned installation company founded in 1930 and headquartered in Hoogkarspel, Noord-Holland. The company delivers and installs modern installations across electricity, (drinking) water, heating, and air treatment for the residential construction sector, and reports a production capacity of approximately 1,000 homes installed per year, ranging from apartments to detached houses.

The company operates through two specialized service departments — Woningbouw Elektra, responsible for electrical installations and mechanical ventilation, and Woningbouw Loodgieter, responsible for gas pipelines, water supply, rainwater drainage, sanitary facilities, wastewater drainage, and sewage. This dual-discipline structure allows Gebr. Kok to act as a single-source installer for serial residential construction projects. The company holds BRL 6000 certification and is a member of Techniek Nederland, which together authorize it to install and inspect independently without utility company involvement, reducing friction in the contracting process for builders. Its service portfolio is anchored on a single core offering, Seriematige Woningbouw (serial residential construction), targeted at construction contractors and developers active in Noord-Holland.

Gebr. Kok pursues a B2B, direct, sales-led go-to-market, contracting with construction contractors and developers on a project basis for new residential developments. Pricing is not publicly disclosed and no revenue figures are available in the source data. The workforce is sized at 51-100 employees. The company emphasizes reliability, quality, and customer consultation as its operating principles, and has no disclosed parent company, external investors, M&A activity, or funding rounds — consistent with a privately held family business operating continuously in a single Dutch province for over nine decades.
