Rising energy prices: how to reduce your bill through energy renovation in Switzerland

In Switzerland, the energy issue is at the heart of households' concerns in 2026. Despite a relative stabilization after successive shocks, electricity and gas prices remain subject to high volatility. Between global geopolitical tensions and the massive investments required by the Energy Strategy 2050, the cost of each kilowatt-hour weighs heavily on family budgets.

In this context, many homeowners are seeking concrete solutions to reduce their expenses. While everyday energy-saving actions are a first step, they quickly reach their limits in old or poorly insulated buildings.

Energy renovation is now the most sustainable response to control your bills, improve your comfort, and guarantee the value of your property in the Swiss real estate market. With Avenir Rénovations, you benefit from comprehensive support to structure your project and optimize your subsidies.

A tense energy context in Switzerland

The situation in Switzerland is explained by several structural and international factors that directly impact your bill.

Geopolitical instability and market prices

International conflicts continue to disrupt gas and oil supplies in Europe. Switzerland, although autonomous in part of its electricity production, remains dependent on European markets to balance its network, which transmits price volatility to the final rates paid by consumers.

The transition to decarbonized heating

New cantonal energy laws impose increasingly strict restrictions on the replacement of oil or gas boilers. This transition to electrification (heat pumps) requires better-insulated buildings to be truly cost-effective.

Energy-hungry buildings

In Switzerland, buildings are responsible for about one-third of CO2 emissions. Nearly half of the Romandy real estate stock is still heated with fossil fuels, making households vulnerable to increases in environmental taxes and global market prices.

Energy renovation: your best financial protection

To no longer suffer from price increases, it is necessary to act on the overall efficiency of your home.

Insulation: the number one barrier

Effective thermal insulation helps retain heat in winter and coolness in summer. By addressing key points, you drastically reduce your needs:

• The roof and attics: the most significant source of thermal loss.
• The facades: essential for protecting the structure and stabilizing temperature.
• Window replacement: switching to triple glazing has become the norm to eliminate drafts and noise.

Next-generation heating systems

Replacing an oil heating system with a heat pump (PAC) is one of the most effective measures in 2026. Combined with proper insulation, it allows you to reduce your energy expenses related to heating and hot water by three times.

Independence through photovoltaic solar energy

Installing solar panels on your roof allows you to produce your own electricity. In 2026, with the rise of storage solutions (batteries) and increased federal aid, self-consumption becomes the safest way to protect yourself against future network tariff increases.

Financing your work: the Building Program and the CECB Plus

Switzerland offers generous aid schemes to encourage renovation, but they require rigorous planning.

1. The Building Program: Each canton (Vaud, Geneva, Valais, Neuchâtel, Fribourg, Jura) has its own catalog of subsidies for insulation, heat pumps, and solar energy.
2. The CECB Plus: The Cantonal Energy Certificate for Buildings (CECB Plus) is often the mandatory key to unlocking significant aid. It is a comprehensive audit that defines the most cost-effective renovation scenarios.
3. Tax deductions: In Switzerland, almost all expenses related to energy renovation are deductible from your income tax, representing a significant immediate financial gain.

Avenir Rénovations: expertise tailored to the Swiss market

Successfully completing a comprehensive renovation in Switzerland requires coordinating many trades and adhering to demanding technical standards.

A single point of contact for all your work

Our franchisees act as a general contractor. We manage your entire project (insulation, heating, windows, roofing) with a single contract and a full guarantee. This simplifies communication and ensures the thermal coherence of your home.

Mastery of cantonal specifics

We understand local requirements (MoPEC 2014, cantonal energy laws) and assist you in administrative procedures for obtaining permits and subsidies.

Enhancing your property value

A property rated A or B on the CECB sells for a higher price and more quickly. In a tight Swiss real estate market, energy performance has become the primary selection criterion for buyers.

Anticipate to no longer suffer

The rise in energy costs is no longer a passing phenomenon but a lasting evolution. Delaying your work means allowing your expenses...
