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.
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.
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.
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.
