What will new windows really cost you?
Two schemes can stack on the same window project: a regional grant of up to 40% (capped at €7,500 per dwelling) and the IRPF tax deduction of up to 40% (max €3,000). Set your budget, province and property type to see the honest final figure — and remember the deduction for dwellings ends 31 December 2026.
