How do Brussels Renolution heating grants work?
The Renolution scheme unifies Brussels Energy and Renovation grants. Payouts depend on the installed technology (air-to-water heat pump, hybrid heat pump, thermodynamic water heater, thermal controls) and your household income bracket (Category I: higher income, Category II: middle income, Category III: lower income).
Strict deadlines apply: your online IRISbox application must be submitted within 12 months of the final invoice, backed by itemized invoices listing exact technical criteria (SCOP rating, installer RESCERT ID, decommissioning of any old oil tank).
