How to obtain your grants and renovation aids in Belgium?

Introduction

In Belgium, whether you are located in Wallonia or Brussels, there are many and advantageous renovation aids. Regional grants, zero-interest loans, VAT reductions, and tax benefits are all levers that allow you to renovate your home while keeping your budget in check. But be careful: these aids are subject to specific conditions and must follow specific procedures. A forgetfulness or a procedural error can make them inaccessible.

This page explains to you, step by step, how to obtain your renovation aids, taking into account the specificities of each Region, and shows you how Avenir Rénovations supports you to secure the entire process.

Why follow a rigorous procedure?

Implementing a renovation project is complex. When you seek public financial aid, the Region or tax administration requires guarantees: compliance with work, energy performance, use of professionals, respect for deadlines, etc.

By following a rigorous approach, you ensure:

  • That you do not lose the right to aid
  • To optimize the amount of grants
  • To combine several schemes without error
  • To avoid administrative delays or refusals

With Avenir Rénovations, each project is prepared considering these imperatives to help you save time and money.

Procedures in Wallonia: steps to follow

1. Check that your housing is eligible

First and foremost, ensure that the building meets the conditions for accessing housing grants:

  • Be located in Wallonia (excluding the German-speaking Community)
  • Have been built more than 15 years ago
  • Be intended for housing for at least 50% of its area
  • Be occupied or made available in accordance with the conditions set by the Region (primary residence, rental, occupation by a relative...)

2. Have a housing audit conducted (often mandatory)

To unlock most grants in Wallonia, a housing audit conducted by an accredited auditor is essential. This audit allows:

  • To assess the energy performance of the housing
  • To propose a prioritized renovation plan
  • To identify the works eligible for aid

The auditor then sends an audit report to the Region, which initiates the process.

Exception: for works limited to roof insulation or roofing, the audit is not mandatory.

3. Submit your "audit" grant application

You must submit your audit grant application within 8 months of receiving the report. This can be done via:

  • The website logement.wallonie.be
  • Your personal space Mon Espace
  • A Guichet Énergie Wallonie

Once validated, the housing audit grant is paid quickly, even if the works have not yet started.

4. Start the works after validation

Once the audit is recorded, you can have the recommended works executed by one or more contractors registered with the Crossroads Bank for Enterprises. Never start a project before this step.

Attention: the works must comply with the technical criteria specified in the report (R values, certifications, types of materials...).

5. Submit your "works" grant application

As soon as the works are completed, you must:

  • Fill out a grant application form
  • Attach all detailed invoices, proof of payment, and technical annexes
  • Send the file within the imposed deadlines (before September 30, 2026, for the current regime)

A receipt will be sent to you, and the Region has several weeks to validate and pay the amounts.

Procedures in Brussels: RENOLUTION user guide

1. Check eligibility conditions

The housing must:

  • Be located in the Brussels-Capital Region
  • Be at least 10 years old
  • Be designated for habitation
  • Be renovated by an accredited contractor
  • Be the subject of a grant application before the start of the project

2. Create your account on IRISbox

The Brussels Region centralizes all procedures on the IRISbox platform. By creating a personal account or one in the name of a co-ownership, you gain access to:

  • Grant application forms
  • Technical guides
  • File tracking

3. Prepare your application file

Before submitting your application, gather:

  • The signed quote from the company
  • The technical sheets of the materials or equipment
  • A plan of the housing or a diagram of the intervention
  • The occupancy or ownership certificate

Once completed, the file is submitted for verification. In case of non-compliance, you have 60 days to correct the errors.

4. Start the works

The works can begin once the application is sent. Ensure compliance with the execution deadlines, technical standards, and the supporting documents required at the end of the project.

5. Send documents after works

At the end of the project, you must submit:

  • The paid invoices
  • Before/after photos
  • The validated technical sheets
  • A certificate of completion (in some cases)

The grant amount is paid after complete verification. Processing typically takes 4 to 12 weeks depending on the period and the workload of the administration.
