Renovation grants by region
All three Belgian regions offer substantial renovation grants: Brussels (RENOLUTION premiums), Wallonia (energy and renovation premiums), and Flanders (Mijn VerbouwPremie). Grants can cover 30-70% of renovation costs depending on income and work type. Additional support includes green loans and tax incentives.
Overview by region:
| Region | Main programme | Covered works | Application |
|---|---|---|---|
| Brussels | RENOLUTION | Insulation, heating, windows, ventilation | renolution.brussels |
| Wallonia | Primes energie + renovation | Insulation, heating, windows, audit | logement.wallonie.be |
| Flanders | Mijn VerbouwPremie | Insulation, heating, windows, total renovation | mijnverbouwpremie.be |
How to apply for grants
The typical grant application process: 1) get quotes from certified contractors, 2) apply for the grant before or after works (depending on region), 3) have the works carried out by certified professionals, 4) submit invoices and proof of payment, 5) receive the grant.
Key points to remember:
- Certified contractors: most grants require works to be performed by certified professionals
- Technical standards: insulation and other works must meet minimum technical standards
- Application deadlines: grants must typically be applied for within a set period after completion
- Income conditions: higher grants are available for lower-income households
- Cumulation: some grants can be combined with tax incentives and green loans
Grant conditions change regularly. Always check the current rules on the official regional website before starting works. Some grants must be applied for before the works begin, others after completion. Meeting the wrong procedure can result in losing the grant.
Tax incentives and green loans
Beyond direct grants, additional financial support is available:
- Federal tax reduction: for certain energy-saving works (roof insulation). The amount varies annually
- Green loans: favourable interest rates for energy renovation through regional programmes and participating banks
- Third-party financing: programmes where upfront costs are repaid through energy savings
- Local municipal premiums: some municipalities offer additional grants on top of regional premiums
For landlords with multiple properties, the combined benefit of grants, tax incentives and improved rental income can make renovation financially attractive even without considering the legal obligations.
