Do you reside in Brussels or Wallonia and are considering renovation work in your home? Insulation, heating, ventilation, energy improvement, or health standards: numerous financial aids are available in 2025 to support your projects. Each Region has its own system of grants, loans, and tax benefits. In parallel, federal schemes complement these supports.
On this page, we offer you a comprehensive overview of the grants, loans, and tax reductions available in French-speaking Belgium. You will find essential information to assess your eligibility, understand the procedures, and prepare your project properly, with the support of a recognized professional like Avenir Rénovations.
Belgium, like its European neighbors, has committed to drastically reducing greenhouse gas emissions and improving the energy performance of its real estate by 2050. Older, poorly insulated, or outdated homes represent a significant portion of the country's energy consumption. That is why the Regions have implemented ambitious schemes to encourage the renovation of residential buildings.
These aids pursue three main objectives:
They take the form of renovation grants, low-interest loans, tax reductions, or reduced VAT, depending on the nature of the work and the applicant's situation.
Wallonia groups its financial aids under the Housing Grants scheme. This system covers a wide variety of works, provided that the housing is over 15 years old and that the works are carried out by accredited professionals.
The amount of the grant depends on the type of works and is multiplied according to the income category of the household. A prior housing audit is generally required to trigger the process, except for works limited to the roof (the housing audit is the new name for the energy audit since 2019).
| Income category | Reference income | Multiplier |
| R1 | ≤ €26,900 | x6 |
| R2 | ≤ €38,300 | x4 |
| R3 | ≤ €50,600 | x3 |
| R4 | ≤ €114,400 | x2 |
| R5 (high income) | > €114,400 | Not eligible |
In addition to the grants, the Walloon Region offers zero-interest financing solutions, depending on your situation:
These credits allow for pre-financing of the projects without immediate contribution, particularly for households with modest or medium incomes.
In Brussels, various aids have been grouped under the RENOLUTION scheme, active since 2022. It is aimed at individuals, landlords, condominiums, and property managers.
In addition to the Regions, the Belgian federal government grants certain tax advantages:
In Wallonia only, taxpayers can benefit from a 30% tax reduction on roof insulation work, capped at €3,900 per year. The conditions are strict: building occupied for at least 5 years, sufficient thermal resistance, approved contractor...
For all renovation work carried out in a dwelling over 10 years old, the VAT rate is reduced to 6% instead of 21%, provided that:
In addition to Housing Grants and zero-interest loans, other schemes exist:
Some Walloon municipalities grant local subsidies for facade renovation, installation of solar panels, or beautification of housing. The amounts vary greatly depending on the available budgets. It is advisable to inquire with the urban planning department or the housing department of your municipality.
If you take out a mortgage for the purchase or renovation of a home in Wallonia, you can benefit from a free insurance that kicks in in case of loss of income (dismissal, incapacity...). This aid aims to secure households weakened by repayment burdens.
Offered by SWCS, the Accesspack is a mortgage loan with favorable conditions intended for first-time buyers wishing to buy a property to renovate. It can include the work from the granting of the loan, without having to go through separate financing.
In Wallonia, energy counters located throughout the provinces provide free information on:
