How it works
Energy grants in Switzerland generally stack at three levels: federal (Building Programme + one-time PV payment), cantonal (each canton has its own schedule) and sometimes municipal (additional premiums from energy-conscious communes).
A well-prepared grant application significantly increases the final amount. Our team prepares and files your application on your behalf, at no extra cost: the grant is paid directly to you, never to us.
The 2026 figures shown on this page are indicative. The final amount is validated by the authority after review (1 to 6 months depending on canton and technology).
