The Prêt vert bruxellois is a socially inclusive financing program launched by the Brussels-Capital Region to support energy-efficient renovations in residential buildings. It offers interest-free or low-interest loans to homeowners, tenants, and landlords who wish to improve the energy performance of their properties. The initiative is part of Brussels’ broader climate strategy and renovation roadmap known as Renolution.
The program aims to:
• Reduce energy consumption and carbon emissions in the residential sector
• Support low- and middle-income households in accessing renovation financing
• Encourage sustainable building practices
• Complement existing renovation bonuses and subsidies.
Vision: A climate-resilient Brussels where all residents live in energy-efficient, comfortable homes.
Mission: To remove financial barriers to renovation by offering accessible loans tailored to household income and renovation needs.
Main Activities
The Prêt vert bruxellois provides:
• Loans up to €25,000 for eligible renovation works (e.g., insulation, heating systems, windows, solar panels)
• Flexible repayment terms based on income level
• Zero or low interest rates, depending on household income
• Integration with Renolution bonuses, allowing applicants to combine loan and grant support
Applicants receive technical and administrative assistance through regional partners to guide them through the process.
Target Audiences
The program is open to:
• Homeowners and tenants in the Brussels-Capital Region
• Landlords renting to low-income tenants
• Co-ownerships (syndics) seeking to renovate shared building elements
Eligibility and loan conditions vary based on income brackets, with special provisions for vulnerable households.
The Prêt vert bruxellois has helped hundreds of households initiate energy-saving renovations that would otherwise be financially out of reach. By combining technical support with tailored financing, it empowers residents to contribute to Brussels’ climate goals while improving their living conditions.
