What OnderhoudNL does

Koninklijke OnderhoudNL is a private Dutch entrepreneurs' association (ondernemersorganisatie / brancheorganisatie) founded in 1880, representing approximately 2,000 member companies across seven segments: painters, glaziers, property maintenance, total contractors, restoration painters, industrial surface treatment, and self-employed (ZZP) professionals. It is the designated cao SAVG (Collective Labor Agreement) negotiation party for the painting, finishing, property maintenance, and glazing sector and represents the industry in NEN norm committees for paints/varnishes and glass for construction. The organization is governed by a member-elected Bestuur with oversight from a Raad van Toezicht, operates from Gouda (Tielweg 16) and Waddinxveen (Coenecoop 5) with a staff of approximately 59, and holds the Koninklijke (Royal) designation in recognition of its 140+ year continuous history. Core service lines span the MijnOnderhoudNL member portal, first-line Ledenadvies, the Vakwerk Plusgarantie quality label, market intelligence (BrancheBarometer, Materiaalkostenindex), and a national consumer-facing campaign ('Wij onderhouden van Nederland').

The product portfolio is organized around eight themes — Arbo & Milieu, CAO, Duurzaam onderhoud, Kwaliteit, Ondernemen, Opleiden & Ontwikkeling, Marktinformatie, and Techniek & Innovatie — and includes specialized tools such as the Loonkompas (digital wage calculator), Windlastbeglazingstabellen, Glasvraagbaak, and the Hechtingsproefkit adhesion test kit. The AI-ledenadvies tool on the public homepage answers natural-language member questions across multiple languages by retrieving from website content and routing complex topics to subject-matter staff. Training is a major line of business: more than 60 branch-specific programs delivered both as open-enrollment at Dutch locations and in-company/maatwerk, covering VCA safety, RGS (Resultaatgericht Samenwerken), Vaktechniek (spray painting, glazing, metal conservation with ISO17024 personal certification), Leermeester master craftsman certification, Management & Leadership (including the 20-year-old Masterclass Jong Management), and Communication. Over 10,000 trainees have completed OnderhoudNL programs since 2017.

Revenue is generated primarily through membership subscriptions (base fee plus a turnover-related contribution plus sector levies, with trial members receiving one year free) and paid training/education services priced with explicit member versus non-member/aspirant-member differentials and charged excluding 21% VAT. Distribution combines three regional sales managers (North, Mid, South) doing direct outreach, a self-serve member portal, and the consumer-facing company search directory that channels demand back to member firms. The Innovatiefonds, effective January 2026 with an annual €500,000 budget, replaced the previous Stichting Bedrijfstakheffing model and is overseen by the Raad van Toezicht, funding member-driven collaborative projects in education/training, occupational health/safety, and market strengthening.

Direct peers

• NOA (Nederlandse Ondernemersvereniging voor Afbouwbedrijven): Dutch trade association for finishing trades (afbouwbedrijven) including plastering, drywall, flooring, and related activities. Adjacent peer covering trades that frequently combine with OnderhoudNL's painting and maintenance work in total-maintenance contracts.
• Bouwend Nederland: Dutch construction and infrastructure employers' association representing construction and maintenance contractors. Closest peer as a Dutch sectoral employers' organization covering adjacent construction, infrastructure, and maintenance work; overlaps OnderhoudNL in maintenance contracting and collaborates via joint subgroups such as Vakgroep Glas.
• PDCA (Painting and Decorating Contractors of America): U.S. trade association for painting and decorating contractors. International equivalent of OnderhoudNL's painting segment; useful comparator for association business models in the painting trade across geographies.
• FOSAG: Federation of entrepreneurs in cleaning and building services in the Netherlands. Direct peer as a Dutch sector association for facility and property maintenance services, with overlapping member demographics and CAO exposure.
• Vereniging ION: Dutch association for industrial surface treatment companies. Direct peer in the industrial coating segment, joint research partner on the Bresle-test reliability study, and NEN norm collaboration partner with OnderhoudNL. Highly relevant given the overlap in industrial maintenance activities.

Broad incumbents

• Aedes: Association for Dutch housing corporations representing institutional property owners. Strategic partner of OnderhoudNL on the RGS methodology and similar sector-wide protocols, but operates on the demand side (property owners) rather than the contractor side that OnderhoudNL represents.

Others

• ISSO: Dutch knowledge center for building installations and energy technology. Adjacent ecosystem player publishing sector technical publications and standards, comparable to OnderhoudNL's technical-knowledge role but focused on HVAC and building services.

Regional players

• Bundesverband Farbe Gestaltung Bautenschutz: German federation for the painting, design, and building protection trades. Comparable regional peer in the DACH region, with analogous training, collective-agreement (Tarifvertrag), and technical-standards responsibilities.
