What Walloon Region renovation grants exist?

Wallonia runs the “Primes Habitation” scheme: renovation grants scaled by the works done and household income, worth up to roughly 1,680 euros per act for many jobs (source: Certinergie and Lisa Energie, 2026). Larger grant tracks require a housing survey, the official Walloon logement assessment, first.

The main renovation support in Wallonia is the “Primes Habitation” programme, a single framework covering a range of works from roofing and insulation to heating and other energy improvements. Two variables set the amount: the type and scale of the works, and the household’s income band, so a lower-income household undertaking substantial works receives more than a higher-income one doing minor jobs.

For many individual works, the grant runs up to roughly 1,680 euros per act (source: Certinergie and Lisa Energie, 2026). These figures move with policy, so treat the number as an order of magnitude and confirm the current schedule before you budget. The point to hold on to is that the aid is real and meaningful, but tied to what you actually do and what you earn.

The counter-intuitive step trips people up: to unlock the larger, staged renovation grant tracks, you must first commission a housing survey, the Walloon logement assessment, carried out by an approved professional. It maps the works and their order, and the bigger subsidies flow only once that survey is in place. Skipping it can mean forfeiting the top tier of support.

Renovation aid is a Walloon regional scheme, so Brussels and Flanders run their own, different programmes. Note too that improving a poor Energy Performance Certificate (PEB) rating both attracts grants and protects value, since Wallonia caps rent indexation on F and G rated homes.
