Switching to a sustainable heating system is one of the most worthwhile investments in maintaining the value of your property in 2026. The cantons' national building program forms the financial backbone of the Swiss heating revolution. Whether you rely on the independence of an air-water heat pump or prefer the convenience of a district heating connection — there is generally considerable funding available for both systems. But behind the generosity of the state, there is an important legal and administrative hurdle that determines the success or failure of your funding application. The decisive question of the “claim” must be answered in a differentiated manner in 2026. While both technologies are eligible for funding, there is no automatic legal claim to the payout. The funding is awarded within the limits of available cantonal budgets. Anyone who arrives too late or ignores the formal criteria goes blank, even if the chosen system was ecologically perfect. The “first come, first served” principle applies, which makes early and precise owner due diligence essential when planning.

Ask questions about a propertyBoth air-water heat pumps and district heating connections are eligible for funding as part of the building program. However, there is no legal claim to the funds; the commitment is made in accordance with available budgets. A combined “double claim” for both systems at the same time is usually ruled out, as the funding is aimed at replacing the main fossil heating system. The application must be submitted and approved before construction begins.
In order to receive funding from the building program in 2026, the most important condition is the replacement of a fossil heating system (oil or gas) or a conventional electric heating system. The cantons are primarily promoting the shift away from fossil fuels to renewable alternatives. So if you replace an old oil heater with a heat pump, you qualify for the basic package. The same applies to connections to a heating network, provided that it is primarily supplied with waste heat or renewable sources.
An often underestimated point is the building permit year for the property. Many cantons restrict funding to buildings built before the year 2000, as modern new buildings must already meet stricter energy standards. In addition, above a certain amount of funding — usually from 10,000 francs — an official GEAK-Plus (building energy certificate with advisory report) is absolutely necessary. This report serves as proof to the canton that the planned measure makes sense in the context of the entire building envelope.
Although the building program has a national umbrella, the cantons have authority over the specific amounts. In 2026, there are significant differences here: While some cantons such as Zurich or Bern offer very aggressive funding rates of up to 18,000 francs for heat pumps, other regions are more likely to promote heating networks. It is therefore worthwhile to compare the cantonal programs precisely before deciding on a system.

The combination with photovoltaics is also interesting in 2026. Some cantons pay additional bonuses if the heat pump is powered directly by their own solar power. District heating connections often support not only the connection itself, but also the dismantling of the old tank systems and the necessary adjustment of the heat distribution (e.g. new pipes in the basement). These additional contributions can have a massive impact on the profitability of a system and should be included in every calculation.
Since you can usually only claim funding for one main system, choosing between heat pump and district heating is a strategic decision. The funding for the district heating connection is often slightly lower than for a geothermal probe heat pump, but covers a larger percentage of the significantly lower connection costs. Anyone seeking maximum independence accepts the higher costs of the heat pump and benefits from the high one-time subsidy, while the recipient of district heating often benefits from lower initial costs with moderate funding.
Important to know: Subsequent switching between systems is hardly encouraged in 2026, as the ecological benefits of switching from “renewable to renewable” are rated as low. In fact, you only have a single shot free to use the state treasury for your heating system renovation. Take advantage of this moment for a comprehensive economic audit that takes into account both one-time subsidies and long-term energy costs.
Is there a claim for both systems? Yes, both are eligible, but you must be aware that funds are limited and the conditions must be met strictly. In 2026, funding is more attractive than ever before, but bureaucracy requires precise preparation.
In summary, anyone who wants to financially cushion the energy revolution within their own four walls must submit the application before the first craftsman enters the cellar. The combination of a building program, cantonal bonuses and potential tax deductions can massively reduce net investment. Professional support and a current GEAK report are your best allies to secure the maximum funding amount for your new, green heating system.
