What Interfit does
Interfit is a full-service installation company (totaalinstallateur) founded in 1980 and headquartered in Winschoten, Netherlands, operating within the Interwinn Group alongside its sister company Interfurn BV. The company delivers electrical, mechanical, plumbing, climate control, and sustainable energy installations for both residential and business customers across the Northern Netherlands provinces of Groningen, Friesland, and Drenthe. Its business spans six verticals: residential, commercial buildings, laboratories and chemistry, manufacturing/industrial, healthcare institutions, and education/offices.
The company's technical capabilities include StabiCAD 9 for CAD-based installation design, building management systems (GBS) for automated facility control, air handling units with heat recovery (WTW), and proprietary in-house manufactured fume hood air monitoring units with VAV systems for laboratory safety applications. Interfit holds ISO 9001, ISO 14001, VCA, and SGS BRL 100 F-gassen certifications and is a member of Techniek Nederland, enabling it to bid on regulated commercial and government projects.
Interfit generates revenue through three streams: one-time installation project services (professional services model), recurring annual maintenance contracts with 24/7 emergency service (subscription model), and professional inspection and certification services under NEN3140 and NEN-14175 standards. The company operates via direct field sales and contractor referrals (notably with Bouwbedrijf De Boer), with marketing through its website, social media, and project showcases. Notable complex projects include a rapid COVID-19 test kit factory conversion for PerkinElmer in Winschoten (2020), a gas-free energy transition for MFC De Klabbe and WA Scholtenschool (2020), and an energy-neutral machine hall installation for Interfurn (2019).
