Winst uit je woning Samen inkopen

What Winst uit je woning Samen inkopen does

Winst uit je woning Samen inkopen (WUJW) is a Dutch private limited company founded in 2011 and headquartered in Haarlem that operates as the largest intermediary in the Netherlands for collective home energy renovation. The company aggregates homeowner demand across 100+ partner municipalities and routes it to a vetted network of 300+ insulation and installation companies, bundling procurement of cavity wall, floor, roof, facade and glass insulation, heat pumps (hybrid, all-electric, all-electric ready), and solar panels. Homeowners are reached through municipal direct mail, a postcode-checker on winstuitjewoning.nl, and door-to-door energy coaches via the Energiebespaardienst; an independent advisor home visit produces a personalized Bespaarplan and a one-time €29 advisory fee is charged for insulation or glazing measures.

The core technology is a Mendix-based web platform that handles resident registration, postcode eligibility, per-municipality action pages, contractor coordination, and subsidy tracking. The platform integrates with RVO subsidy systems through Simpel Subsidie (the exclusive subsidy administration partner), Google Analytics, and the Nationaal Warmtefonds for homeowner financing. Free ISDE and SVVE subsidy application support is a core service, alongside value voucher administration in certain municipalities. The company's recently announced roadmap extends into home batteries, insulating doors, attic floor insulation, and sun blinds.

The business model is a hybrid of B2G service fees and intermediation. Municipalities commission WUJW to run collective purchasing actions and pay for the Energiebespaardienst via Nationaal Isolatieprogramma budgets; WUJW also embeds margins in contractor pricing. Homeowners do not pay for participation in a municipal action or for the Bespaarplan, aligning incentives between the municipality, the contractor, and the homeowner. Revenue concentration sits with municipal contracts rather than individual homeowners. The company was placed into bankruptcy, and a December 2, 2025 press release announced a doorstart with operations continuing for ten specific municipalities (Drechtsteden, Provincie Utrecht, Beuningen, Elburg, Haarlem/Zandvoort, Schagen, Steenbergen, Waddinxveen, Waterland, Zoeterwoude) while all other actions are paused and no new sign-ups are accepted.

Revenue model

1. Collective Purchasing Intermediation: Winst uit je woning bundles homeowner demand and negotiates group rates with insulation and installation companies (uitvoerders). Revenue is generated through fees charged to municipalities for organizing and facilitating the collective purchase actions, and/or through margins embedded in the contractor pricing. Homeowners pay the contractor directly; WUJW does not charge homeowners for participation.
2. Subsidy Administration Service: Free service to homeowners for ISDE and SVVE subsidy applications, facilitated in partnership with Simpel Subsidie. WUJW is commissioned by municipalities to process and pay out subsidy funds on their behalf (municipal subsidy, not ISDE). The service is bundled into the action offering.
3. Energiebespaardienst (Energy Advisory Visits): Door-to-door energy coaching service deployed in municipalities, funded by municipal budgets (Nationaal Isolatieprogramma). Coaches advise on small energy-saving measures and activate residents toward larger renovations. Revenue derives from municipal service contracts.
4. Value Voucher (Waardebon) Administration: For certain municipalities, WUJW administers value voucher schemes funded by municipalities, where residents receive vouchers to offset costs of energy-saving materials purchased from approved retailers or contractors. WUJW validates claims and processes reimbursements.

Expansion highlights5 records

Broad incumbents

• ENGIE Nederland: Dutch arm of a global energy and services group offering heat pumps, insulation, and home sustainability services to households; competing incumbent with much broader portfolio but overlapping Dutch homeowner offerings.
• BAM Wonen: Major Dutch construction group's residential division; broader portfolio across new-build and renovation, with growing presence in the Dutch home sustainability market that overlaps with WUJW's homeowner segment.
• VolkerWessels: Large Dutch construction group with residential renovation and sustainability activities across multiple brands; comparable as a broad incumbent operating in WUJW's downstream contractor ecosystem.
• Heijmans: Large Dutch construction and renovation contractor with residential sustainability offerings; broader portfolio than WUJW but competes for the same municipal and homeowner renovation demand.
• Eneco: Major Dutch energy supplier increasingly active in residential heat pumps, insulation, and solar; competes with WUJW for the same homeowner renovation wallet share, though Eneco's offerings are vertically integrated rather than intermediated.

Direct peers

• Klimaatroute: Dutch regional energy transition platform running municipal programs to activate homeowners on insulation and heat pump measures; directly comparable GTM via municipal commissioning and group purchasing.
• Energieloket: Dutch regional energy advice platform connecting homeowners to subsidized renovation measures and vetted contractors; operates the same intermediary value chain as WUJW for municipalities across multiple Dutch regions.
• Duurzaam Bouwloket: Dutch intermediary that advises homeowners on sustainability measures and partners with municipalities to run energy renovation campaigns — directly comparable business model to WUJW's collective purchasing platform.

Others

• Simpel Subsidie: Dutch subsidy administration specialist that processes ISDE/SVVE applications on behalf of WUJW; closely linked as a partner, but also represents an adjacent ecosystem player that could bypass WUJW and serve municipalities or homeowners directly.
• Nationaal Warmtefonds: Dutch national green financing fund providing the Energiebespaarlening to homeowners. Already a partner of WUJW, but also an adjacent channel that could substitute for WUJW's intermediation if municipalities shifted subsidy flow.
