Subsidies & incentives
In Belgium, this type of work usually does not qualify for a fixed regional grant like insulation or heat pumps do. The biggest financial impact usually comes from VAT, renovation loans, and local exceptions.
What usually helps
- For homes older than 10 years, work carried out by a contractor often qualifies for 6% VAT instead of 21%.
- Mijn VerbouwLening in Flanders and ECORENO in Brussels can help spread a larger renovation budget.
- Municipalities may offer extra support for accessibility, de-paving, or neighbourhood renewal, but this is never automatic.
Always check
- Whether a notification or permit is required.
- Whether the work forms part of a broader renovation that does qualify under a regional scheme.
