Questions to ask before hiring a craftsman in Luxembourg

Ask for the autorisation d'etablissement number or QR code and verify that the authorised activity matches the work. Since business permits are digital, serious providers should be able to point you to the permit number or QR code on quote, invoice, website or site panel. For cross-border providers, do not assume the same permit model; ask for proof that they may legally provide the service in Luxembourg.

Ask what is included, excluded and provisional. For housing work, ask whether the provider will request AED approval for direct 3% VAT before work starts, or whether the quote uses the normal VAT rate and leaves the owner to claim a refund. Ask how foreign-company invoices, subsidies, change orders, waste, parking, diagnosis and control-body or Creos costs are handled. A quote that cannot separate labour, material, VAT and optional lines is not ready for comparison.

Ask who is on site, who supervises, which trades are subcontracted, how delays are communicated and how access, dust, protection and neighbours are handled. For larger jobs, payment should follow visible milestones, not vague dates. The handover should include a written acceptance/reception step with reservations listed clearly; that matters later if defects need to be claimed.

Fynd's AI assistant can turn these questions into a project brief before contact: authorisation to check, commune, photos, affected trade, permit/VAT/Creos angle, handover documents and decision criteria. Each provider then receives the same facts, and the category pages help you move from a checklist to real profiles instead of generic search results.
