NFOŚiGW revealed the latest statistics of the Clean Air 2025 program

The National Fund for Environmental Protection and Water Management summarized the new, reformed edition of the Clean Air program, which was launched on March 31, 2025. Over seven years, the total funding paid out to applicants for home thermal modernization amounted to almost PLN 17.5 billion. What has changed for the better in Poland?

The latest edition of the Clean Air 2025 program

Over the past five months, owners of single-family houses in Poland have been able to apply for funding for comprehensive thermal modernization or for replacing “smokestacks” with ecological heat sources. Support also covered the preparation of an energy audit of the building along with recommendations for optimal heating solutions.

Data for the period from March 31 to August 29 of this year show that Poles submitted nearly 28,000 applications, on the basis of which almost 8,000 contracts were signed for a total amount of over PLN 440 million. Under the new edition of the program, more than PLN 7 million has already been paid to beneficiaries. These figures do not include grants for flood victims and subsidies for gas boilers financed from FEnIKS funds.

Almost 11,500, that is 40 percent of all applications, were submitted by Operators. This is the only form of application that makes it possible to use pre-financing and the highest level of support (up to 100 percent). Independent applicants can count on basic support (up to 40 percent) or enhanced support (70 percent).

Controversial boilers returned to the list

Eligible costs of projects implemented under the Clean Air program include, among others, the purchase and installation of a heat pump, installation of central heating, insulation of the building, and replacement of doors and windows. Pellet boilers were originally included on the List of Green Devices and Materials (ZUM), but this point was temporarily suspended.

Only this week, NFOŚiGW announced that the Institute of Environmental Protection – National Research Institute (IOŚ-PIB), after consultations with boiler manufacturers, confirmed that these devices meet the program requirements and therefore return to the ZUM list. However, it is not permitted to use funding for the purchase of biomass boilers that allow the installation of an emergency grate or pre-furnace.

How does thermal modernization clean Poland’s air?

Between 2019 and 2024, the Clean Air program helped modernize 453,000 low-energy-efficiency buildings. With the support provided, 393,000 heat sources were replaced, which reduced energy consumption by 7.6 GJ annually. In terms of national air quality, this means reducing annual emissions by 11,300 tons of PM10 dust; 13.7 tons of benzo(a)pyrene; and more than 3.2 million tons of CO2.

The largest number of thermal modernizations was carried out between 2022 and 2024, with the record year being 2023, when the energy efficiency of more than 124,000 buildings was improved.

The new edition of the Clean Air 2025 program is being carried out under changed rules. The reform included, among others, making the funding conditions dependent on the owner’s income criterion and the building’s energy standard, the obligation to prepare an energy audit before and after the investment, and the introduction of free beneficiary support through the Operator system.

As Paulina Hennig-Kloska, Minister of Climate and Environment, said: When working on the reform of the Clean Air program, we were guided by three key priorities – above all, combating energy poverty by providing real support to those most in need. Our goal was also to eliminate the so-called horror bills by introducing a mandatory energy standard for buildings and rationalizing expenses, so that abuses would not occur.

Applications can be submitted on a continuous basis until December 31, 2030. Funding payments will be made until 2032.
