Premiums

In Flanders the premium for asbestos removal asks for a certificate from the contractor with their enterprise number.

What the premiums ask of the contractor

Flanders

Flanders (Mijn VerbouwPremie): most work only counts when a contractor does it. The invoice shows the contractor’s name, address and VAT number and Belgian VAT, and the contractor fills in a certificate with their enterprise number. No professional competence is required; a heat pump is installed by an installer with a RESCert certificate. The conditions

Wallonia

Wallonia (primes Habitation): the contractor is registered in the KBO and has access to the profession for the work: roofing and waterproofing for the roof, structural work for walls, joinery and glazing for windows, central heating, air conditioning, gas and sanitary for heating. An electric heat pump also needs electrotechnical activities. The conditions

Brussels

Brussels (Renolution): the contractor is registered in the KBO, VAT registered and has access to the profession where the work needs it. Invoices from 2025 and 2026 don’t qualify for a premium for now; the competence rule still applies. The conditions

For 6% VAT on renovation (a home over ten years old), a VAT-registered contractor invoices you directly.

Firmatlas gives no legal advice. Check your premium’s conditions before you sign.

What no register shows

• Ask for a written quote with name, address and enterprise number, and compare a few.
• Don’t pay a large deposit. Agree on payment in stages as the work progresses.
• Ask for the ten-year liability insurance certificate when the work needs an architect.
• Ask for references of work nearby and go and look.
• Check that the enterprise number on the quote is this company’s.
