Energy grants in Wallonia 2026: Primes Habitation and Rénopack
In 2026 Wallonia applies a transitional Primes Habitation regime until 30 September. Mandatory housing audit, 4 income categories, €50,000/home cap over 5 years, combinable with Rénopack 0%. On 1 October 2026, a new Rénopack/Rénoprêt system replaces everything.
This article covers only the 2026 Walloon situation. For the Belgian overview (VAT, federal deduction, comparison of 3 regions), first read the complete Belgium guide. See also our hub on Wallonia.
The transitional regime until 30 September 2026
Until 30 September 2026, the Walloon Primes Habitation system operates under a specific transitional modality. After that, a completely new mechanism takes effect. For renovation projects to be completed this year, this transitional regime remains the applicable framework.
The 4 income categories explained
The granted amount depends directly on your category. Here is the simplified structure:
| Category | Who is targeted | Grant multiplier |
|---|---|---|
| R1 | Low incomes | ×6 (maximum grant) |
| R2 | Modest middle incomes | ×4 |
| R3 | Mid-to-high incomes | ×2 |
| R4 | High incomes | ×1 (base grant) |
The gap between R1 and R4 is therefore considerable: for the same works, an R1 household can receive up to six times more than an R4 household. This is the core of the Walloon redistribution system.
The Rénopack — a 0% loan up to €60,000
Beyond the Primes Habitation, Wallonia offers the Rénopack: a public loan at 0% (for low and modest-middle incomes) or at preferential rate, to finance renovation works.
| Feature | 2026 detail |
|---|---|
| Cap | €60,000 per home |
| Rate | 0% for R1-R2, preferential rate for R3-R4 |
| Repayment period | 30 years maximum |
| Manager | SWCS (Société wallonne du crédit social) and SWL |
| Combinability | Fully combinable with Primes Habitation, 6% VAT, federal deduction |
Audit (mandatory) → request Rénopack 0% by including the Primes Habitation → carry out works → request grants after works → grants directly repay the Rénopack. This is the most advantageous scenario of the current Walloon regime. To plan financing alongside a purchase, see approaching the bank for a mortgage.
How to combine aids in Wallonia
The Walloon system is deliberately combinable. The five levers to activate together:
The analysis order to follow: 1. audit (if required) → 2. estimate Primes Habitation → 3. request Rénopack including grants → 4. carry out works → 5. request grants after works. For comparison with the other regions, see Brussels and Flanders.
The turning point of 1 October 2026
From 1 October 2026, the transitional Primes Habitation regime ends. A new global system replaces it, whose main contours have already been announced by the Walloon government.
No more grants paid "post by post". The mechanism shifts to a logic of preferential-rate loans (expanded Rénopack and Rénoprêt) targeting climate goals and the global energy quality of homes.
- Simplified audit, with a unified renovation plan
- Rénopack cap possibly raised to €100,000
- Grants progressively integrated into the loan (no separate request needed)
- Faster processing times announced for 2027
Works completed before 30 September 2026 → current system (transitional Primes Habitation). Works starting or completed after 1 October 2026 → new system. Don't hesitate to contact SPW Logement or schedule a housing audit to anticipate the transition.
