Which energy grants am I entitled to in Brussels in 2019?

Grants covering up to 50% of the bill have been agreed for three main types of work: audits, insulation, and heat recovery or production.

In 2019, the budget for energy grants in Brussels is slightly lower, falling from 22 million euros to 18 million. However a new grant has appeared and some have been increased.

Main changes:

  • An increase in grants for external wall insulation (B2) and replacing boilers (C1);
  • A new grant for vulnerable households for the compulsory check on gas appliances;
  • The possibility of applying for energy grants for building extensions and for both major and minor renovation work;
  • Simplification of administrative conditions for households;
  • Alignment of income categories with the ones for renovation grants.

Type A grants for energy audits and studies

Performing a domestic energy audit on your home, shared accommodation or commercial building helps you detect your home’s weaknesses and take effective measures.

You can also carry out a feasibility study if you are considering installing ventilation, cogeneration, solar water heating, a wood-fired heating, renewable energy, a heating network, etc.

The grant could be up to:

  • € 400 for domestic accommodation
  • or € 3,000 for a shared residential or commercial building.

Type B grants for insulation and ventilation

Insulation grants are between  8 and € 75/m2. That does not include the additional bonus for choosing natural insulation or the energy savings the work will allow you to achieve.

The amount of the grant varies depending on:

  • the type of wall
  • the materials
  • your income category (the lower your income, the higher the grant)

Do you plan to invest in controlled mechanical ventilation (CMV) with heat recovery? This investment may entitle you to a grant of between € 1,250 and € 3,500, depending on your income.

  • efficient gas convector heaters: up to € 300
  • regulation devices (thermostatic valves and thermostats or optimisers): up to € 100
