Assess the building as a whole first
Insulation, ventilation, heating and energy generation are connected. The right solution depends on the condition of the building and its consumption.

Energy renovation in Brussels
Compare contractors for insulation, solar panels, batteries, heating and heat pumps as part of an energy renovation in Brussels.
Several trades may need to be coordinated
An energy renovation can combine roof work, insulation, windows, electricity, solar panels, a battery and the heating system.
Compare the overall performance of the solution
Beyond the equipment price, compare system sizing, installation, any required adaptations, after-sales support and warranties.
What to specify for your energy renovation
Insulation, windows, ventilation, heating, heat pumps and solar generation interact. It is useful to assess the building as a whole before comparing individual equipment.
- current insulation condition
- existing heating type
- current windows and glazing
- goals: comfort, consumption or overall renovation
Questions to consider before requesting quotes
Should I start with the heating system?
Not necessarily. Improving the building envelope can change heating demand and therefore the sizing of a future system.
Can I combine several types of work in one request?
Yes. The form lets you select several categories to describe a broader energy-renovation project.
Are grants or incentives included?
They depend on the rules in force when the project is carried out. Check your eligibility and the official conditions separately.
