Berlin, July 7, 2026

The federal government plans to substantially lower subsidies for the installation of climate-friendly heating systems such as heat pumps starting next year, while at the same time making them more strongly graduated according to income and the origin of the equipment.

The level of eligible costs, for example for installing a heat pump, is set to decrease starting next year, according to a letter from the Finance Ministry to the Budget Committee in the Bundestag. Until now, homeowners can apply for a basic subsidy of 30 percent of the costs for installing a modern heating system. The eligible costs are capped at 30,000 euros. According to the letter, which was available to the news agency AFP on Tuesday, this amount will drop to 28,000 euros next year and then decrease by an additional 750 euros every six months.

The previous additional subsidy of 30 percent of costs for households with a taxable annual income of less than 40,000 euros is also to be further differentiated. For households with incomes below 30,000 euros per year, the bonus is to rise to 40 percent, and for incomes between 40,000 and 50,000 euros, a bonus of ten percent of eligible costs will be granted. This increases subsidies for low-income households while noticeably reducing support for those in the middle-income range.

Cuts in detail

In addition, the surcharge of currently another 20 percent in funding for replacing a still functional heating system that is at least 20 years old will decrease by four percentage points every six months starting next year. The so-called climate bonus for the early replacement of an old heating system is also set to decline more quickly than previously planned. According to this, the subsidy would expire in 2029. For instance, the efficiency bonus for heat pumps is to be eliminated, and switching from district heating to a different heating technology will no longer be subsidized.
