Renovation in Belgium: what changes in 2025 for regional grants

Renovation in Belgium: what changes in 2025 for regional grants

In Belgium, renovating a property can be particularly interesting thanks to the numerous regional aids implemented to encourage the improvement of the housing stock. In 2025, several changes are expected in the three Regions of the country – Wallonia, Brussels-Capital, and Flanders – particularly regarding the grant conditions, allocated amounts, and administrative procedures. In this article, we review what changes this year, and how Avenir Rénovations supports you in making the most of the available grants.

Why are renovation grants changing in 2025?

Belgian regional authorities regularly adapt their support measures for renovation to meet several priority objectives:

  • Reduce energy consumption in homes;
  • Combat energy poverty;
  • Accelerate the transition to more sustainable housing;
  • Encourage renovation rather than new construction.

In 2025, these objectives are reinforced by European climate commitments and the need to achieve a nearly energy-neutral real estate stock by 2050. As a result, significant adjustments have been decided in each region to better target priority works.

New developments in Wallonia in 2025

The reform of the Housing grants has fully come into effect

Since July 1, 2023, the old Energy and Renovation grants have been replaced by a single system: the Housing grant, which remains valid in 2025 but with some adjustments.

What changes in 2025:

  • Revaluation of certain categories of priority works: roof insulation, window replacement, ventilation.
  • Simplification of forms and centralization of procedures via the My Space platform.
  • Wider access to housing audits for low incomes: a step that is now almost essential to obtain major grants.

Grant amounts remain indexed:

The amount of the grant still varies according to two criteria:

  • The household income (5 income categories);
  • The type of works carried out, with a multiplier coefficient applied to a flat rate.

To remember: Grants can cover up to 90% of the cost of works for certain low-income beneficiaries, within limits.

Avenir Rénovations support

In Wallonia, Avenir Rénovations helps you to:

  • Identify eligible works;
  • Schedule a housing audit with a certified expert;
  • Prepare the required documents for your grant applications.

Thanks to our local expertise, we guide you step by step to optimize available aids without the risk of administrative errors.

What is evolving in Brussels in 2025

A strengthened budget and a focus on energy

The Brussels-Capital Region continues to strengthen its Renolution program, established in 2022. In 2025:

  • The allocated budget increases by 25 million euros;
  • Incentives for heavy energy renovation work are further encouraged: wall insulation, installation of heat pumps, double flow ventilation.

New features in 2025:

  • Revised rates for structural work (structure, roofing, stability);
  • Stackable bonuses with municipal aids, notably in Ixelles, Schaerbeek, and Forest;
  • Introduction of a bonus for comprehensive renovations planned across multiple work areas.

Administrative simplification

A new online simulator allows Brussels households to:

  • Check available aids in just a few clicks;
  • Estimate the amounts accessible based on their tax profile.

Avenir Rénovations by your side

  • Selecting the most cost-effective work areas;
  • Optimizing the phasing to obtain a comprehensive renovation bonus;
  • Coordinating with partner municipalities.

In Flanders: focus on Mijn VerbouwPremie

The "Mijn VerbouwPremie" grant remains relevant

Launched at the end of 2022, this unique grant now combines the former aids for renovation and energy. In 2025, Flanders focuses on simplification and efficiency.

Changes in 2025:

  • Increased ceilings for roof insulation, external insulation, and high-performance boilers;
  • Introduction of a new energy renovation score (REN-score) mandatory for certain works;
  • More transparency on processing times: applications are now tracked in real-time via the digital platform.

Unchanged access criteria:

  • Amounts linked to income and the nature of the work;
  • Requirement to use recognized contractors (aannemers).

Tailored support with Avenir Rénovations

Our teams based in Flanders help you to:

  • Compile a complete application file via the Mijn Burgerprofiel platform;
  • Identify the most financially supported works;
  • Plan a coordinated construction site to limit costs and delays.
