Swiss grants for window replacement
Replacing windows alone does not automatically qualify for a Swiss grant. Measures vary by canton and often support a whole-building renovation, a Minergie standard or a GEAK improvement rather than windows as a standalone item. Check the canton programme and submit any required application before work begins.
Eligibility depends on the canton and project
The Building Programme is implemented by the cantons. Windows may form part of a supported whole-building renovation without being eligible as a standalone measure. The current canton page and exact programme category always take precedence over a commercial summary.
Canton of Bern: check the building category
Bern's current overview lists efficient buildings and renovations based on GEAK classes and Minergie. It does not state a general payment per replaced window. Applications for eligible measures must be submitted before work starts. The responsible office is the Amt für Umwelt und Energie (AUE).
Canton of Fribourg: windows within a complete renovation
Fribourg's measure for a complete renovation with Minergie certification includes replacement windows within the relevant whole-building work. This does not make a standalone window replacement automatically eligible. Confirm conditions and deadlines with the cantonal Energy Service.
A safe process before ordering
Use the Building Programme portal to select the property canton and exact measure, then confirm eligibility with the competent authority. A quotation supplies technical data but is not a grant decision.
- Identify the canton and renovation type.
- Read the current conditions and validity date.
- Distinguish a standalone measure from a complete renovation.
- Submit the application before work where required.
- Only count the grant after an official decision.
Check tax treatment separately
A possible tax deduction depends on the owner's situation, the expense and current tax rules. It is not automatic and should not be confused with a grant. Seek confirmation from the tax authority or a qualified adviser.
