Renovating your home in Belgium in 2026 represents a strategic investment in the face of energy costs and increasing environmental standards. To support homeowners, the three regions maintain substantial financial aid schemes, although their mechanisms differ considerably. This guide details the amounts, eligibility conditions, and administrative procedures for each region.
In 2026, Belgian renovation policy focuses on heat decarbonization and high-performance thermal insulation. The objective is clear: to move the housing stock toward a PEB A rating by 2050.
Even before discussing grants, the most important fiscal lever remains the reduced VAT rate. For homes over 10 years old (private use), renovation works benefit from a 6% VAT rate instead of 21%. This measure applies to both labor and materials, provided they are supplied and installed by a registered contractor such as CULA.
In all three regions, the grant amounts are indexed to household income.
Update October 2026: the RENOLUTION grants are no longer available. New applications have been suspended since August 2024, and in February 2026 the Brussels government confirmed the scheme has ended for good: no invoice dated 2025 or later qualifies for a grant.
Zero-rate loans are to replace them: the budget agreement of 4 October 2026 plans for them to take effect in spring 2027, but their conditions are not published yet. Meanwhile, the support that remains in Brussels is 6% VAT for homes over 10 years old, the Housing Fund's Ecoreno loan and some municipal grants.

Update October 2026: the temporary 2025-2026 Habitation grants scheme ended on 30 September 2026 (last day to apply). Since 1 October 2026, Wallonia supports energy renovation with loans rather than grants paid after the works:
The implementing decrees set the amounts and conditions: always check logement.wallonie.be before signing.
Update October 2026: since 1 March 2026, owners in income categories 1 and 2 (the highest) no longer receive Mijn VerbouwPremie for roof, wall or floor insulation or high-efficiency glazing: only heat pumps and heat pump water heaters remain subsidised for them. Nothing changes for categories 3 and 4. The EPC label premium was abolished on 1 January 2026.
Amounts depend on your income and the type of work: simulate them on vlaanderen.be/mijn-verbouwpremie.
This is the priority item. In 2026, the minimum thermal resistance (R) required is 4,5 m²K/W in all regions to obtain grants. A thickness of 18 to 24 cm of mineral wool is often required.
The overall U-value of the frame (Uw) must generally not exceed 1,5 W/m²K. The switch to triple glazing is strongly encouraged in Brussels with specific bonuses.
In 2026, installing a heat pump to replace an oil boiler is the most highly subsidized operation. Note: the installation must be carried out by a RESCERT certified technician.
Building the file is the stage where the risk of refusal is highest. Here are the points to watch:
It is possible to combine regional grants with:
Note: You cannot apply twice for a grant for the same work item from two different organizations.
1. Can I carry out the work myself and receive grants? No. In 2026, almost all grants in Belgium require the use of a registered and certified contractor. Buying materials alone does not qualify for aid.
2. How long does it take to receive the money? After validation of the file by the administration, expect between 3 and 6 months for the actual payment into your bank account.
3. Can tenants apply for grants? In Brussels, some tenants can submit an application with the landlord's written consent for certain works (e.g., insulation), but it is generally the owner who manages the file.
4. Is the grant capped relative to the cost of works? Yes. In most cases, the total amount of grants cannot exceed 70% to 90% of the total invoice amount including VAT.
Navigating the administrative maze of Belgian grants can be complex. In 2026, technical and documentary rigor is the key to not losing the thousands of euros in aid to which you are entitled.
At CULA, we don't just execute your renovation and insulation works. We support you in understanding the technical criteria required by the regions and we provide all the documents and certificates necessary for the success of your grant application.
