Belgium's renovation subsidies are managed at the regional level, creating three distinct systems: Wallonia's Primes Energie, Brussels's Renolution premiums, and Flanders's Mijn VerbouwPremie. Each region has different rules, amounts, and income conditions. This fragmentation makes Belgium the most complex country in our system — but also the one where an API brings the most value, since navigating three sets of rules manually is painful.
Varies by region. Wallonia: income-based with 4 categories. Brussels: income bonus available. Flanders: property value-based. All regions require the property to be used as housing and the works to be performed by registered contractors.
Update frequency: Each region updates independently, typically in January.
