De WarmteTransitiemakers

What De WarmteTransitiemakers does

De WarmteTransitiemakers B.V. is a privately held Dutch consultancy headquartered in Utrecht, founded in 2018, specializing in advisory services for the Dutch heat transition (warmtetransitie). The firm supports Dutch municipalities, provincial governments, and housing corporations in transitioning neighborhoods and buildings from natural gas to sustainable heating alternatives, with the explicit national objective of a gas-free built environment by 2050. Its client base includes named municipalities such as Utrecht, Den Haag, Groningen, Eindhoven, Haarlem, and Houten, plus the provinces of Zeeland and Zuid Holland, and the woningcorporaties (housing corporation) segment.

The company's core offerings span five service lines: (1) Gebied aardgasvrij maken, centered on the Warmteprogramma (municipal heat roadmap), wijk/buurtanalyse (technical-economic neighborhood analysis), and wijkuitvoeringsplannen (neighborhood implementation plans), with specialized methodologies for historic centers and modern neighborhoods; (2) Bewonersparticipatie, including participation strategy and tooling for resident engagement; (3) Verduurzamen van vastgoed, covering residential complex analysis, heat solution feasibility studies, heat company contracting support, and VvE (homeowners association) sustainability advisory; (4) Onderzoek en innovatie, providing applied research perspectives; and (5) a Toolbox aardgasvrij of proprietary digital tools — Aardgasvrijhuis.nl, De Warmtepompvergelijker, De Warmtetransitie Monitor, BegrotingsTool Uitvoeringsorganisaties, and Warmteprofielentool — that support household-level guidance, heat pump comparison, transition monitoring, budgeting, and heat profiling. The firm co-developed the 'Aardgasvrij met de Omgevingswet' service with KuiperCompagnons, integrating heat transition expertise with the Dutch Environment Act, and in June 2026 joined the Stella Groep consortium alongside De Groene Grachten, Greenvis, Endor Energy, and NIWT.

Commercially, De WarmteTransitiemakers operates as a sales-led professional services firm with 11–50 employees, generating revenue through direct advisory engagements with municipal and provincial governments and housing corporations. Pricing is not publicly disclosed and engagement is via bespoke contracts rather than packaged products. The firm reaches clients through LinkedIn, a knowledge bank with masterclasses, webinars and FAQs, a bi-monthly newsletter, and direct outreach, and is aligned with the national NPLW (Nationaal Programma Lokale Warmte) support framework that channels structural support to local heat transition programs across the Netherlands.
