What Keijsers Martens does

Keijsers Martens elektro- en installatietechniek BV is a family-owned total installation company headquartered in Ysselsteyn, North Limburg, Netherlands. The company provides integrated electro-technical (E) and mechanical/Werktuigbouwkundige (W) installation services across three declared verticals: Industry, Utilities/Commercial Buildings (Utiliteit), and Agri & Food. Its service portfolio spans eight lines: consulting and design, electro-technical installations, inspections and certifications (SCIOS Scope 10/8PI, NEN 3140/1010, thermographic, EBI-PO-PI, BRL6010 legionella control), building installations, climate systems, sustainability systems (heat pumps, solar, WTW, pellet heating), sanitary installations, and 24/7 service and maintenance.

The firm's revenue model combines one-time installation project work (new construction, renovation) with recurring service and maintenance contracts and inspection/certification fees. Its E&W combination — delivering both electrical and mechanical installation under a single contract — is positioned as the primary differentiator, enabling integrated building management systems and coordinated project delivery for industrial, healthcare, logistics, agri-food, education, and commercial real-estate clients in North Limburg and Eastern Brabant. Go-to-market is field-based B2B direct sales; pricing is quote-based and not publicly disclosed.

Under fourth-generation director Edwin Keijsers, the firm employed 52 staff at merger and now operates in a 51-100 employee band. On 7 May 2025, it received the Hofleverancier (Royal Warrant) designation in recognition of 125 years of continuous operation.
