Klimabonus 2026: conditions and procedures

Klimabonus 2026 supports qualifying energy measures in residential buildings. For building-envelope renovation, the building must notably be more than ten years old from the building-permit date. Conditions depend on the measure and application dates.

Owner-occupiers are not the only applicants: landlords and certain groups or legal entities may also apply. A dwelling, hotel and commercial building must not automatically be treated as eligible under the same scheme.

Measures, areas, materials, performance, equipment and dates determine the rates. Total cost alone cannot produce a reliable calculation.

Depends on income, household and eligible state aid, with cumulation limits. No automatic percentage of the works budget.

Distinguish free introductory Klima-Agence advice from an accredited adviser’s technical assignment, which may be charged and subsidised subject to conditions. Works cost or a CPE class improvement alone cannot calculate a grant.

For renovation with energy advice, obtain approval in principle before works begin. A separate procedure exists for a single measure without full advice. Prepare quotes, areas, performance data and evidence, then follow the chosen scheme’s deadlines.

Separate grants, VAT relief and bank financing. Cumulation depends on each scheme’s rules. A loan must be repaid; it does not reduce economic cost like a grant. A grant paid after works does not immediately fund a deposit.
