Energy grants in Flanders 2026: Mijn VerbouwPremie after reform

On 1 March 2026, Flanders deeply reformed Mijn VerbouwPremie. Categories 1 and 2 (mid-to-high income) can now only request the heat pump grant. Categories 3 and 4 retain full access. Compensation: Mijn Verbouwlening expanded to €60,000, plus combinable Fluvius grants.

This article covers only the 2026 Flemish situation. For the Belgian overview (VAT, federal deduction, comparison of 3 regions), first read the complete Belgium guide.

The 1 March 2026 reform

Flanders implemented a major Mijn VerbouwPremie reform on 1 March 2026. The system retains its 4 income categories, but access to grants is heavily restricted for the higher categories.

Category Access before reform Access after 1 March 2026
Category 1 (high incomes) ✅ Full ⚠️ HP grant only
Category 2 (mid-to-high incomes) ✅ Full ⚠️ HP grant only
Category 3 (modest middle incomes) ✅ Full ✅ Full
Category 4 (low incomes) ✅ Full ✅ Full
⚠️ Concrete impact

If you fall into category 1 or 2 and you plan insulation, frames or condensing boiler: no more Flemish grant for these works. Only the heat pump remains subsidized. For those in categories 3 or 4, the system remains fully active.

The heat pump: the central 2026 grant

The Flemish heat pump grant remains accessible to all 4 categories and is the year's main investment incentive. Flanders set caps to limit exclusively applicable use for high incomes.

Heat pump type Cat 1-2 (after reform) Cat 3-4
Air-water €1,500 €4,000 (cat 3) / €6,000 (cat 4)
Geothermal €1,500 €5,000 (cat 3) / €8,000 (cat 4)
Air-water hybrid €800 €1,800 (cat 3) / €2,700 (cat 4)
Thermodynamic water heater €400 €800 (cat 3) / €1,200 (cat 4)
✅ Combination with federal 6% VAT

On top of the Flemish grant, the federal 6% VAT remains applicable to heat pump installation, even in new homes from 2026. Add the federal 30% deduction (on roof insulation) and possibly a Fluvius grant, and the total support becomes substantial.

The full system for categories 3 and 4

For middle and low incomes (categories 3 and 4), Mijn VerbouwPremie remains fully accessible. Main subsidizable works:

🧱
Roof insulation Up to €8/m² (cat 3) or €12/m² (cat 4). Combinable with federal 30% deduction.

Fluvius — additional combinable grants

Beyond Mijn VerbouwPremie, Fluvius (Flemish grid operator) offers additional grants, especially for heat pumps and electrical grid upgrades.

Examples of 2026 Fluvius grants: €300 to €800 for heat pumps (depending on type and COP), €200 to €400 for electrical installation upgrades needed for an HP, EV charging point grants. Fully combinable with Mijn VerbouwPremie and federal deduction.

Flemish pitfalls in 2026

⚠️
Planning works without knowing your category If you're in cat 1 or 2 and plan major insulation, anticipate: only the HP grant remains accessible. Reconsider the type of work to maximize levers.
⚠️
Forgetting Fluvius grants Often forgotten because separate from Mijn VerbouwPremie. Systematically check the Fluvius site after your project.
⚠️
Exceeding the 12-month application deadline Strict: past the deadline, no grant possible. Plan your administrative work in time.
