Sustainability grants by region
Frequently asked questions
Can any Belgian company apply for sustainability grants?
Most sustainability grants are open to SMEs, large companies, and even non-profits. Eligibility depends on your registered office location (region), the type of investment, and sometimes your sector.
Do I need an energy audit before applying?
For larger grants like Ecologiepremie+, an energy audit is often required or strongly recommended. Smaller grants for specific equipment (e.g., solar panels) usually don't require one.
Can I combine sustainability grants with tax deductions?
Yes. Belgian companies can often combine regional grants with federal energy tax deductions, as long as the total public aid doesn't exceed the maximum intensity (typically 60–80%).
How quickly are sustainability grant applications processed?
Processing times vary. Equipment-specific grants (solar, heat pumps) are often approved within 4–8 weeks. Larger project grants like Brussels Climate Fund can take 3–6 months.
Are there grants for circular economy projects?
Yes. Flanders offers specific circular economy grants through VLAIO, and Brussels has dedicated programs for resource efficiency and waste reduction through Innoviris and Bruxelles Environnement.
