The future support scheme for energy renovation, which will come into force on 1 October 2026 in Wallonia, will evolve towards a single subsidised loan system, focused on the most energy-guzzling homes. The aim? To guarantee the efficiency, sustainability and clarity of the system for users.
At the start of the legislature, the previous support system showed its limits. The multiplication and overlapping of schemes across more than 120 different grants, processing times of two years and a budget overrun of €1 billion threatened the very sustainability of the aid granted to households. Faced with this situation, the Walloon Government took the decision to launch a thorough reform. A temporary system, remaining the most advantageous in the country, was first put in place to avoid an abrupt halt to support that a moratorium would have caused, while progressively restoring financial balance.
The ambition now is to definitively turn this page by building a simple, clear, efficient and financially sustainable scheme, capable of sustainably supporting the people of Wallonia. To this end, the Government approved, this Thursday, the terms of the new support scheme, which will come into force on 1st October 2026. The aim? Eradicate energy-guzzling homes.
In practice:
- Focus on energy-guzzling homes and requirement for a 'label leap': regional support will henceforth be reserved for renovation projects targeting homes:
- with a PEB label G or F and whose works will enable them to reach at least label D (ESPEC ≤ 340 kWh/m².year);
- with a PEB label E and whose works will enable them to reach at least label C (ESPEC ≤ 255 kWh/m².year).
This approach aims to eliminate energy-guzzling homes, which today represent one of the main challenges of the Walloon housing stock. It also aims to maximise the impact of every public euro invested, by supporting projects of a certain scale.
- Support calibrated according to income and the energy savings resulting from the planned works
- Increased loan amount: the amount that can be borrowed will be raised to €75,000 for single-family homes, compared to €60,000 previously. This is to better reflect the real cost of the energy renovations covered by the new scheme.
- Clarity and simplicity: a single tool, the loan, will structure regional support around two pillars:
- The Rénopack, namely an interest-free loan combined with a reduction in the amount to be repaid akin to a subsidy. This scheme, already well known to citizens, will apply to households in categories C1, C2 and C3.
- The Rénoprêt, namely a loan with interest, depending on the income category of the applicant household. This loan will be reserved for people in income category C4, landlord-owners and co-owners' associations.
| Income category1 | Rate | Reduction in the amount to be repaid2 |
| C1 Up to €28,900 | 0 % | 50 % |
| C2 From €28,900.01 to €41,100 | 0 % | 40 % |
| C3 From €41,100.01 to €67,100 | 0 % | 15 % |
| C4 From €67,100.01 to €122,800 | Variable | 0 % |
1 Amounts indexed as of 1 January 2026. A reduction of €5,000 per dependant will also be applied to the amount of taxable income.
2 Including a 5% increase for the use of eco-materials
Regional support will be calculated globally for the whole set of eligible works (roof, insulation, window frames, heating, etc.) of the renovation project, rather than item by item. This change will simplify procedures and encourage a coherent approach to energy renovation.
It should be noted that the Rénoprêt may offer a zero interest rate in the specific case of works to adapt housing for disability, as well as rehabilitation works made necessary following a recognised natural disaster. In other cases, it will offer a preferential rate compared to market conditions (banks).
- Coherent pathway: to access the loans, applicant households will be required to carry out an audit prior to the works. The audit, which is part of the list of eligible investments, makes it possible to identify priority works, plan the various renovation stages and avoid situations where certain investments prevent or complicate future interventions.
For households in income category C1, the energy assessment carried out as part of granting a Rénopack may count as the audit. Its cost may be included in the financing.
- Flats and co-ownerships: support will be adapted to the specific features of apartment buildings.
For works carried out in private areas, each dwelling may benefit from financing (Rénopack/Rénoprêt) of up to €60,000. However, the income of the applicant household may not exceed €122,800.
For works carried out in common areas, co-owners' associations may benefit from an interest-free loan (Rénoprêt) of up to €60,000 per dwelling, with an overall cap set at:
- 000 euros for co-ownerships with fewer than 20 units;
- 000 euros for co-ownerships with 20 units or more.
The works must be based on an audit specific to apartment buildings and comply with the recommendations set out therein.
- Budgetary control: in order to guarantee the long-term sustainability of the support system, and thus avoid the past budget overruns, Wallonia will each year set out, in the budget decree, the envelope allocated for the following financial year. This monitoring mechanism will ensure ongoing tracking of the commitments made by the Region and guarantee the long-term viability of the scheme for the benefit of citizens.
- Strengthened support: the reform also aims to better guide households throughout their renovation project.
Today, numerous stakeholders are already active in Wallonia (Energy Centres, Espaces Wallonie, Local Energy Renovation Platforms, SWCS, FLW, Réno+, etc.), but their action remains insufficiently coordinated. Citizens are often required to deal with multiple contacts, while certain areas remain less well covered and in-depth support remains too limited.
The Government therefore intends to create a genuine “renovator's pathway”, so that would-be renovators are no longer left alone facing the complexity of a renovation project. The aim is to offer structured support from initial advice through to follow-up after the works, including diagnosis, financing and the works themselves.
In line with European recommendations, this system will be based on “one-stop shops”. This does not involve creating a new administration or a new building, but rather better coordinating existing operators in order to offer citizens a simple point of entry, whatever body subsequently intervenes, and a uniform level of support across the whole of Walloon territory.
In due course, three levels of support will be offered depending on households' needs:
- Level 1: information and advice
- Level 2: personalised support to prepare the project, seek financing and complete administrative procedures;
- Level 3: almost complete management of the project, including monitoring of the works.
Support will be rolled out progressively:
- From 1 October 2026, the new scheme will rely on existing structures, whose remits will be clarified and harmonised.
- From 1 January 2028, the future Walloon Housing Agency will oversee the target scheme, with an operator accreditation system, common tools and reinforced territorial coverage.
Cécile Neven, Minister for Energy and Housing: “With this new scheme, we will now concentrate public resources where they have the greatest impact, that is to say primarily on energy-guzzling homes. We are also simplifying access to support, strengthening aid for the households that need it most, and guaranteeing a financially sustainable framework, enabling us to continue supporting citizens over the long term in their renovation journey. In doing so, we are turning the page on a system of grants that was too complex, too costly and too ineffective.”
