Good to know:
- Basel-Stadt is one of the few cantons to offer subsidies for windows and private charging points.
- In areas served by district heating, the grant for a heat pump is halved.
Municipality grants
Riehen and Bettingen also offer their own schemes. To find out about support available in your municipality, search using your postcode on francsenergie.ch (energiefranken.ch in German).
A simple example
A 200 m² house heated by oil carries out the following work:
- 10 kW air-to-water heat pump: CHF 10,500;
- insulation of 120 m² of façade and roof: approximately CHF 6,000 (at the basic rate);
- CECB Plus assessment prior to the work: CHF 1,000;
Estimated total: approximately 17,500 CHF in cantonal funding, plus any funding from the municipality and the tax deduction.
Steps to follow in order
- Obtain a CECB Plus (GEAK Plus in German-speaking Switzerland) if you are planning several improvements: this will set out the order in which the work should be carried out.
- Request quotes from local tradespeople.
- Submit your application via the canton’s Building Programme platform and to your municipality before work begins.
- Wait for confirmation before starting.
- Carry out the work within the timeframe specified in the grant approval letter.
- Send the supporting documents (invoices, photos, certificates) to receive the grant.
