"Window grants Wallonia Brussels" mostly means two things: Wallonia's regional housing grants (primes habitation) and, in Brussels, the RENOLUTION scheme. Both have conditions you need to check before ordering if you buy windows without installation, usually an energy audit and work carried out by a registered company. In early November 2026, the Brussels region's website said there was no government decision on RENOLUTION grants for invoices dated 2025 and 2026. Below we explain what this means if you buy windows from us and fit them yourself or with your own installer.
Window grants Wallonia & Brussels: the rules in Wallonia
Wallonia subsidises work that improves a home's insulation, including replacing windows. The rules for these grants have changed several times in recent years, and the amounts depend on household income, so we don't quote figures here. The current conditions are on the region's official websites (energie.wallonie.be and wallonie.be).
According to the scheme's description, typical conditions are:
- an energy audit of the home (audit logement) before work starts,
- work carried out by a professional or a company registered in the Belgian business register (BCE),
- requirements for the insulation value of the new windows, the Uw value.
Alongside grants there are renovation loans (in Wallonia, Rénopack). Check their conditions on the region's website as well.
What about grants in Brussels?
In Brussels, renovation grants were paid under the RENOLUTION scheme. In early November 2026, be.brussels stated that there was no government decision on grants for 2025 and 2026 and that applications could not be made for invoices from those years. The region also points to the Ecoreno loan from the Fonds du Logement. This may change, so check renolution.brussels or ask the Homegrade advisers before ordering.
What does this mean if you buy windows without installation?
We sell made-to-measure uPVC and aluminium windows and doors online, without installation. Schemes that require a company's invoice for the work may not count windows bought separately and fitted yourself. Before ordering, ask two questions:
1. The authority or an adviser: does the grant cover windows bought separately and fitted by a registered company? 2. Your installer: can they fit windows you supply and issue the invoice the scheme requires?
If the grant requires one company to both supply and fit the windows, buying from us won't qualify. In that case, compare the product price from our configurator plus local fitting against a fitted quote minus the grant. The decision is yours; we simply tell you clearly what we don't do.
What window documents do you get from us?
We have worked with windows since 1997 and have been shipping them abroad since the late 1990s. Every delivery comes with a declaration of performance and CE documentation. The declaration states the window's Uw value, which grant schemes and auditors ask about. Before production you receive a drawing and specification to approve, so you can show the system and glazing to your auditor before paying anything. Compare the Uw of our uPVC systems on the uPVC windows page, and read what the figure means in our article on the Uw value.
Where can you check the current rules?
- Wallonia: energie.wallonie.be and wallonie.be, advisers at the Guichets Énergie Wallonie.
- Brussels: renolution.brussels and be.brussels, advisers at Homegrade.
This is general information, not legal or tax advice. Once you know whether a grant covers your case, build your windows in the configurator. You'll see the price straight away, and we'll prepare a quote including delivery to Belgium within 3 working days.
