The 4 sources of support
- The canton, through the Buildings Programme: this is the main source of support, covering heating, insulation and the CECB Plus.
- The Confederation, through Pronovo: a one-off payment for solar panels, applied for after the system is commissioned.
- The municipality or its electricity supplier: often for solar panels, batteries, advice or a top-up for heating. Search using your postcode on francsenergie.ch.
- Taxes: energy-saving investments are deductible from taxable income, subject to your canton’s rules.
Which projects are eligible for subsidies?
- Replacing an oil, gas or electric heating system with a heat pump, a wood-fired heating system or a connection to district heating.
- Insulation of the façade, roof and floors, paid per square metre insulated provided the performance meets the required standard.
- Initial radiators or underfloor heating, when replacing an electric heating system.
- Solar energy: thermal (hot water) subsidised by the canton; photovoltaic subsidised by the Confederation.
- The CECB Plus (GEAK Plus), which provides the renovation plan.
- Complete renovation to Minergie standards.
- Depending on the canton: ventilation, charging points, batteries, support from a professional (AMO in the canton of Vaud).
