Grants and credits for renovation in Brussels in 2025

Why does the Brussels-Capital Region encourage renovation?

The built environment in Brussels is dense, old, and not very energy efficient. To address climate challenges, improve the quality of life for residents, and reduce energy bills, Brussels has established an ambitious incentive framework through the RENOLUTION grants. Since 2022, these grants have replaced several previous schemes (energy grants, renovation grants, beautification grants, etc.) to simplify access to assistance.

By financially supporting renovations, the Region pursues several objectives:

• Reduce CO₂ emissions
• Enhance thermal and acoustic insulation of homes
• Improve the health standards of buildings
• Adapt buildings to contemporary standards (safety, accessibility...)

What are the RENOLUTION grants for?

The RENOLUTION program offers assistance for over 100 types of work, ranging from energy renovation to building safety, comfort, and accessibility. These grants are available to individuals, condominiums, landlords, and property managers alike.

Eligible works

The main areas covered are:

• Thermal insulation (roof, walls, floors)
• Replacement of frames or glazing
• Efficient heating (heat pump, condensing boiler, biomass stove)
• Ventilation (simple or dual flow systems)
• Sanitary installations and electricity
• Photovoltaic or thermal panels
• Fire safety
• Works for persons with reduced mobility (PRM)
• Treatment of humidity or radon

Bonuses are also possible for comprehensive approaches or grouped renovations.

Who can benefit?

RENOLUTION grants are accessible to:

• Owner-occupiers
• Landlords
• Condominiums (via property managers)
• Tenants in certain cases (if mentioned in the contract or as part of a collective renovation)

How are the grant amounts calculated?

Variables taken into account

The amount of the grants is calculated based on several criteria:

• The income category of the applicant
• The geographical area (certain priority areas qualify for a bonus)
• The type of beneficiary (individual, condominium, landlord, etc.)
• The type of work carried out
• The degree of energy performance achieved

Examples of amounts in 2025

The ceilings vary significantly based on income. For an accurate estimate, using the official RENOLUTION simulator is recommended.

What conditions must be met?

General conditions

• The building must be located in the Brussels-Capital Region
• It must be at least 10 years old
• The work must be carried out by a registered company
• The applicant must be the owner or legal representative
• The application must be submitted before the start of the work

Specifics for condominiums

Condominium associations can submit applications for the common areas of the building (roof insulation, collective ventilation, fire safety...). The grants are then calculated based on a specific grid, independent of the income of the co-owners.

What steps should be followed?

The process is now fully digitized via the IRISbox platform, accessible to all individuals residing or working in Brussels.

Main steps

1. Create a user account on IRISbox
2. Gather the necessary documents: detailed quotes, plans, any certificates
3. Submit a grant application before the work begins
4. Have the work carried out by an approved company
5. Upload proof of completion: invoices, photos, technical sheets
6. Receive the payment after processing the file (a few weeks to a few months)
