Introduction to the Grant System in Wallonia
The Walloon government has set up a grant system aimed at encouraging sustainable home renovations in the Walloon region. These renovation grants have been available for several years, but with the new regional grant system that came into effect in February 2025, the process has been simplified. This system merges the old energy grants and housing grants into one, offering a clearer and more effective solution for owner-occupiers.
The primary goal is to encourage residents to carry out renovation work that improves energy performance and quality of life in their homes. Whether it’s insulation work, roof replacement, or the installation of a heat pump, this financial aid plays a crucial role in reducing project costs.
In the following sections, we will explain how to benefit from these grants, the role of the housing audit, the amount of financial aid based on your situation, and the necessary steps to submit a grant application through a single portal.
Conditions to Benefit from Housing Grants
To qualify for grants in Wallonia, certain conditions must be met. These housing grants are primarily aimed at owner-occupiers of homes located in Wallonia, whether it’s a single-family home, a house, or an apartment building. The renovation must concern your primary residence to be eligible.
The type of work also plays an important role. Among the eligible projects are insulation work, roof renovation, heat pump installation or replacement, and other work that promotes energy savings and health within your home.
The amount of the grants will also depend on the recipient’s income category, ensuring a fair system that adjusts to everyone’s financial situation. The Walloon government ensures that these aids are accessible while encouraging sustainable and environmentally-friendly renovations.
It’s crucial to check the specific conditions for your project before starting your work, especially to find out if a housing audit is required.
Housing Audit: An Often Mandatory Step
As part of the renovation grants in Wallonia, carrying out a housing audit is often a mandatory process for certain types of work, particularly those aimed at insulation or the installation of a heat pump. This audit evaluates the current energy performance of your home and identifies the necessary actions to improve its energy efficiency.
The audit is a key element of the new regional grant system, ensuring that the completed work meets the Walloon government’s quality and efficiency requirements. It’s important to note that some projects can qualify for a grant without an audit, but this remains the exception.
The audit also provides a solid foundation for your grant application, as it specifies the work to be done. By following the criteria set by the Walloon region, you can maximize your chances of receiving a grant.
Understanding the New Regional Grant System in Wallonia
Since January 1st, Wallonia has implemented a new regional grant system that simplifies access to renovation grants. This unified system merges energy grants and housing grants to provide a clearer system for citizens.
This change applies to all types of buildings, including single-family homes, common areas of apartment buildings, and homes managed by a social housing company. The Walloon government has decided that this system will only apply to buildings older than 15 years.
From now on, all grant applications must be submitted through a single portal available on Irisbox. This portal centralizes the grant application form, which must be filled out based on income category, type of work to be done, and the application date. It’s important to note that the housing audit is mandatory for more extensive renovation work, except in some cases without an audit. The goal is to ensure the health of your home and prioritize projects that focus on energy savings.
Conditions, Amounts, and Steps to Benefit from Renovation Grants
To qualify for grants in Wallonia, you must first request an energy audit. This audit determines the nature of the work, and the completed work will be subsidized based on your income category. The amount of the grants can vary significantly depending on whether you’re carrying out insulation work, home renovations, or other types of renovation work. Each grant amount is determined according to a specific rate.
The Walloon Social Credit Company can also intervene as part of a temporary support program, especially if you need to submit a request to maintain your eligibility for grants after a change in your project. It’s essential to allow a 12-month period between the audit and the work on your property, provided it remains your primary residence.
Since February 14, 2025, Revolution Grants are also applicable to homes in the Brussels-Capital Region, with similar administrative procedures. This regional system that combines grants allows you to obtain a grant in a more consistent way, as long as you meet all the conditions.
It is advisable to submit your grant application as early as possible. If there are any changes, you can request to maintain your eligibility for the grant. All grants are listed on the regional portal, and if you are unsure about which grants you qualify for, you can consult an expert or contact the relevant administration. The conditions of the old system remain valid as long as the primary residence is confirmed by a proof of primary residence title.
Summary: What You Need to Do to Benefit from Renovation Grants
Whether you’re carrying out work on homes in Namur, Mons, or Arlon, you can always apply for the grants provided by the region. The aid is extensive and tailored for both renovations in Wallonia and the energy transition.
Focus on Practical Steps to Obtain Your Renovation Grants
To carry out renovation work under the best conditions, it is essential to understand the steps involved in obtaining a grant. The starting point remains the audit, which is a central requirement of the new system. This audit defines exactly which work is necessary and the priority based on the expected energy savings. Without this audit, it’s generally impossible to benefit from the grants provided by the region.
Renovation grants can cover different types of work, but be careful: no application will be accepted if it doesn’t comply with the standardized application form or if it’s incomplete. The application date also plays a crucial role, especially for projects started since February 2025. It’s therefore recommended to plan your grant application in advance to avoid refusals.
The new provisions allow grants to be requested for single-family homes, apartments in apartment buildings, and homes managed by a social housing company. The aid also applies to common areas, as long as they are involved in insulation or health improvement work within your home.
