An estimate, not advice
Indicative estimate, not a contractual offer — the actual terms depend on your own situation and are set by the institution or the tax authority. Check with a professional.
Ratios €/m² = ordres de grandeur marché 2026 (TTC, main d'œuvre incluse), pas des tarifs officiels. Le prix réel dépend de l'état du bâti, des lots et des artisans : demandez toujours plusieurs devis.
Financing the work
Éco-PTZ (the French interest-free loan for energy renovation), a home-improvement loan or a top-up on your mortgage: the terms depend on your bank. Compare before you sign a quote.
