Klomp

What Klomp does

Klomp BV is a Dutch family-owned technical services integrator headquartered in Amsterdam, founded in 1961. The company delivers integrated building technical solutions across four divisions: energy (solar PV, commercial and residential battery storage, EV charging infrastructure, energy management systems), roofing (sustainable, flat, sloped, and safety systems), installation technology (climate, heating, building management, water/sanitation), and management and maintenance (preventive maintenance, technical facility management, inspections). Operations are delivered through nine wholly-owned operating subsidiaries (including Klomp Technisch Buro, Klomp Technisch Beheer, Klomp Dakbedekkingsystemen, Klomp Building Management, Klomp Energie/Green4energy, Klomp Projecten, AVM Service, Klomp Lei- en Zinkwerken, and Hellendplus), enabling specialized execution while maintaining a single-point-of-contact model for clients.

Klomp serves B2B clients in the Netherlands, primarily housing corporations, commercial businesses, real estate owners, and municipalities, with a notable reference portfolio spanning heritage buildings (Kasteel Nederhorst den Berg, Nationaal Holocaustmuseum), cultural institutions (Internationaal Theater Amsterdam), manufacturing (Albeton Amsterdam, Winclove Probiotics), agriculture (Bejo Zaden), and public sector (Gemeente Utrecht, Gemeente Zaanstad). The company's technical differentiation centers on its ability to combine energy generation, storage, and management capabilities to address Dutch grid congestion, as demonstrated by projects integrating HYXIPOWER, Volstora, and Huawei battery systems with real-time EMS from Tibo Energy.

The business model combines project-based installation revenue (one-time contracts for design, installation, and commissioning) with recurring maintenance and management contracts. Pricing is quote-based and not publicly disclosed; the company uses direct enterprise field sales, free initial consultations, and website quote requests as go-to-market channels. The company is privately held with no external institutional investment or public listing.

Direct peers

• Unica: Largest Dutch independent technical installer offering integrated energy, HVAC, electrical and building services to commercial and residential clients. Direct competitor across the same multi-disciplinary stack and Dutch enterprise/corporate customer base.
• SPIE Nederland: Dutch arm of European technical services group SPIE, delivering electrical, HVAC, energy and building management solutions. Comparable integrated technical-services model in the Netherlands.
• Croonwolter&dros: Major Dutch technical services contractor under the TBI group, providing electrical, mechanical, and integrated building installations similar to Klomp's core disciplines. Comparable customer base across utilities, government and real estate.

Broad incumbents

• ENGIE Nederland: Large incumbent energy and technical services provider in the Netherlands with capabilities in energy supply, HVAC, heat pumps, and facility management. Overlaps with Klomp on energy transition and B2B building services but operates at much larger scale.
• Siemens Smart Infrastructure: Global vendor of building management systems, energy management and electrification solutions. Comparable in the BMS/EMS layer that Klomp integrates with partners like PRIVA and Tibo Energy.
• Equans Nederland: European multi-technical services and facility management incumbent (formerly ENGIE Solutions/Fabricom) serving Dutch commercial and public clients. Overlaps with Klomp's installation, maintenance and energy services portfolio but as part of a broader facilities services platform.
• Honeywell Building Technologies: Global building automation and controls vendor whose BMS and HVAC controls ecosystem competes with Klomp's GACS/priva-based offerings. Comparable product category though at a vendor rather than integrator level.
• Johnson Controls: Global incumbent in BMS, HVAC, and energy services for buildings. Comparable in building automation and energy management scope; competes via technology suppliers and integrator partners in the Netherlands.

Regional players

• Heijmans: Major Dutch construction and infrastructure company with a growing sustainability and energy-transition services portfolio. Comparable Dutch B2B and housing-corporation client base, though broader in construction than Klomp's technical-services focus.
• BAM Bouw en Techniek: Dutch construction and technical services group offering integrated building installations and maintenance. Comparable in multi-disciplinary installations and recurring services, but operates at substantially larger scale.
