Good to know:
- New Vaud Energy Act coming into force on 1 January 2027: any replaced heating system must be renewable, and large buildings classified as F or G must be retrofitted.
- The CECB is mandatory when selling a building in the Canton of Vaud.
Municipality grants
Lausanne, Morges, Nyon, Yverdon and many other Vaud municipalities have their own energy funds. 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 5,000;
- insulation of 120 m² of façade and roof: approximately CHF 4,800 (at the basic rate);
- CECB Plus assessment prior to the work: CHF 1,500;
Estimated total: approximately 11,300 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 sets 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.
