Brussels homeowners: the grants you can still claim in 2026

Renovating a dwelling in Brussels is expensive, but the Region and the federal level make several levers available to bring the bill down. The problem isn't a shortage of aids: it's knowing which ones concern you and how to stack them without slipping up. This article runs through, simply, what a Brussels homeowner can still claim in 2026.

For the detail of how the regional scheme works, we've devoted a full article to the Renolution 2026 reform. Here, we take the homeowner's point of view: who qualifies, for how much, and in what order to go about it.

Who can claim a grant in Brussels?

The basic rule is broad: if you are the owner of a dwelling located in the Brussels-Capital Region, you fall within the scope of the Renolution grants run by Brussels Environment. That applies just as much to the owner-occupier as to the owner-landlord renovating a property put up for rent.

What changes from one file to the next is not so much the right of access as the amount. Renolution modulates its grants by the household's income bracket: the more modest the income, the higher the intervention rate. Two neighbours carrying out the same works can therefore receive different amounts.

Renolution: the regional grant, item by item

Renolution is the foundation. It covers insulation, roofing, heating, ventilation, window frames, sanitary conditions. Each item has its own scale and its own cap, and it's the sum of these items that forms your total grant.

Insulation remains the most generous item for most projects: the order of magnitude runs around €60 per m² insulated, capped at roughly €2,700 per dwelling, modulated by your income and the type of insulation. This is a 2026 order of magnitude; the detailed, up-to-date scale is published on renolution.brussels.

The Sibelga grant, which adds on top

Alongside Renolution, Sibelga — the operator of the electricity and gas distribution network in Brussels — offers an energy grant on certain energy-efficiency works, in the region of €450 depending on the work. In the same spirit, installing a balanced (heat-recovery) mechanical ventilation system can open a bonus of around €500, an item that's regularly forgotten even though it weighs on comfort and on the EPC.

• Renolution — regional grant, all items, modulated by income.
• Sibelga — energy grant on targeted works, ~€450 (source: sibelga.be).
• Balanced ventilation bonus — ~€500 for high-performance ventilation.

These amounts remain indicative and depend on the works actually carried out and on their compliance. None of these aids is an automatic right: it is applied for, justified and obtained on file.

6% VAT: the federal lever people forget

Beyond the grants, there's a benefit that doesn't go through a regional channel: the reduced 6% VAT instead of 21% on renovation works to a dwelling over ten years old. It's a federal mechanism (finances.belgium.be) that applies directly to the contractor's invoice, and that stacks with Renolution and Sibelga.

On a substantial project, the gap between 21% and 6% VAT often represents a saving greater than the grants themselves. That's why a credible estimate must show both: the cost before aids and the amount left to finance once the reduced VAT and grants are applied.

In what order to go about it

The efficient method is always the same. First, you price the works reliably — an ABEX-indexed amount, not a price from memory. Then, you match the grants item by item: Renolution, Sibelga, ventilation bonus. Finally, you apply the 6% VAT if the property is over ten years old. The result isn't a frightening gross cost, but a realistic amount left to finance — the one your bank will examine.

That's exactly the sequence a Qote report automates: your items calibrated on the ABEX index, the Brussels grants matched, the reduced VAT built in, the whole reviewed by an expert and presented in a format banks recognise. The grants guide completes the picture for the other regions if you own a property outside Brussels.
