Renovating one's home to make it more energy-efficient is now a priority for many homeowners in Switzerland. With rising energy costs, environmental requirements, and thermal comfort, energy renovation represents a sustainable and responsible investment.
Fortunately, the Confederation, cantons, and some municipalities encourage these efforts by offering numerous financial aids: bonuses, subsidies, and tax incentives.
In this complete guide, Avenir Rénovations Suisse explains how to benefit from these programs, what conditions must be met, and what steps to follow to finance your work under the best conditions.
Swiss subsidies for energy renovation have a clear goal: to reduce energy consumption and CO₂ emissions while supporting homeowners in their projects. These aids offer several concrete advantages.
One of the main advantages of the aids is the immediate reduction in the cost of work. Thanks to these subsidies, it is possible to lighten the bill by 20 to 40% depending on the nature of the project.
For example:
Beyond the immediate savings, energy work increases the heritage value of the property. A better-insulated building, equipped with efficient windows and renewable energy heating, will be more attractive for sale or rental.
Moreover, obtaining a better energy certificate (CECB) improves the rating of the housing and reassures potential buyers.
A well-renovated house can reduce heating or electricity expenses by up to 60%.
The aids thus allow for investment in sustainable thermal comfort, both summer and winter, while decreasing the household's carbon footprint.
The financing of energy renovations in Switzerland is based on several levels: federal, cantonal, and communal. These levels complement each other to encourage individuals to undertake high-performance projects.
The Building Program is the foundation of the aid system. Jointly financed by the Confederation and the cantons, it supports renovations aimed at improving energy efficiency and reducing CO₂ emissions.
Eligible works:
Indicative amounts:
Each canton manages its online application platform and sets its exact amounts.
The cantons have their own complementary programs, often cumulative with the Building Program.
Each canton publishes an official guide to subsidies accessible via its energy website.
Some municipalities or intermunicipalities go further by offering bonuses for ecological projects:
Check with your municipality before starting your work: these local aids are often unknown but very advantageous.
Green energy production installations also benefit from specific supports, notably through Pronovo, the federal agency that manages solar feed-in premiums.
Examples:
Assistance is not automatic. You must meet specific criteria related to the building, the work, and the compliance of the project.
In general, only renovations of existing buildings are eligible. New constructions do not benefit from the same support.
The building or house must be more than 5 years old to qualify for certain grants.
The work must improve the overall energy efficiency of the building:
The products used must meet Swiss standards (SIA, Minergie, CECB) ensuring energy performance.
Some programs require a Cantonal Energy Certificate for Buildings (CECB) or a more comprehensive CECB+.
The energy audit helps identify the weaknesses of the housing and prioritize the work to be done.
The cost of this study is often partially subsidized.
Administrative procedures require rigor and anticipation. At Avenir Rénovations Suisse, we support our clients from the preparation of the file to the execution of the work.
| Type of work | Average amount of aid | Main source |
| Roof / wall insulation | 30–50 CHF/m² | Building Program |
| Heat pump | 2,000 to 8,000 CHF | Canton / Confederation |
| High-performance windows | 100–150 CHF/m² | Canton |
| Photovoltaic panels | 200–400 CHF/kWc | Pronovo (Confederation) |
| Energy audit (CECB) | 300–1,000 CHF | Canton / Municipality |
Many programs are cumulative as long as their compatibility is verified.
For example, it is possible to combine a federal grant with a cantonal bonus and a municipal subsidy.
To optimize energy performance, it is advisable to start with insulation, then replace heating systems.
This approach ensures better efficiency and a more advantageous subsidy calculation.
