What Lammerink Installatiegroep does

Lammerink Installatiegroep is a privately-held Dutch multi-discipline technical installer founded in 1963 and headquartered in Ootmarsum, Netherlands. The company delivers four integrated disciplines: Werktuigbouw (mechanical engineering covering HVAC, plumbing, fire protection, technical gases), Elektrotechniek (electrical distribution, lighting, data networks), Beveiligingstechniek (fire detection, intrusion, access control, CCTV with AI-driven analytics), and Technisch Beheer (ongoing monitoring and maintenance supported by the InstallWorks customer portal). Technical scope spans design using BIM (Revit, AutoCAD/Stabicad), prefabrication of technical spaces, and lifecycle service contracts with reported 24/7 emergency response within one hour and resolution within four hours. Work is anchored by a stack of Dutch regulatory certifications — ISO 9001:2015, VCA**, CCV BORG and fire detection certifications, BRL 6000-21/25, BRL 100/F-gassen, and CO2 Prestatieladder Level 3 — that gate access to public and utility tenders.

The firm serves a vertical mix of developers, construction companies, healthcare institutions, housing corporations, government and public sector (including defense), education, hospitality, and retail/logistics customers across Twente, Groningen, Drenthe, Overijssel and Gelderland. Revenue is generated predominantly through project-based new construction and renovation contracts with one-time revenue recognition, supplemented by recurring technical management and service contracts and reactive maintenance. Go-to-market is consultative enterprise field sales with tender participation for large utility projects and relationship-driven cross-sell into existing accounts. Operations span three locations (Ootmarsum HQ, Groningen branch, Oldenzaal subsidiary Kip Installatietechniek) and partner capacity is augmented through a joint venture with De Groot Installatiegroep and 'Noabers' alliances with regional construction and architecture firms.

The company operates with 230 employees (FY reference period), reports 600+ completed assignments, and references marquee customers including NLR Marknesse, Rijksuniversiteit Groningen (Feringa Building), Van der Valk Hotels across six locations, Tecnotion, ALDI distribution centers, RIVM, defense installations (~200 buildings), the Hof van Saksen resort (555 holiday farmhouses), and Gemeente Apeldoorn's emergency dispatch center. Erik Lammerink is identified as founder, director and owner. Revenue is not publicly disclosed and no external funding, parent company, or M&A activity is recorded.
