Author: Michał Gulczyński

The thermo-modernisation grant scheme supports building renovations which increase energy efficiency or the use of renewable energy sources for heating purposes. Lenders may receive grants to pay off part of the loan taken out to implement such measures. 

Eligible measures shall reduce a building's annual energy demand, annual energy losses or annual costs of heat production or replace existing heat generation plants with renewable or high-efficiency CHP plants (art. 3 Act on Thermo-Modernisation).

Eligible technologies

In general, all renewable energy sources used in heat generation are eligible (art. 3 par. 4 Act on Thermo-Modernisation).

Aerothermal energy


Hydrothermal energy




Geothermal energy




Solar thermal energy



The amount of grant is equal to 20% of the loan received for the implementation of thermo-modernisation undertakings. However, the subsidy may not exceed 16% of the total costs of the modernisation work and may not exceed twice the amount of the anticipated annual savings in energy costs, which were identified through an energy audit (art. 5 Act on Thermo-Modernisation).


The owner or manager of the building in which refurbishment works are conducted (art. 7 par. 1 in conjunction with art. 2 no. 1 Act on Thermo-Modernisation).


Process flow

  • Application. The investor submits an application for a subsidy to the BGK (Bank Gospodarstwa Krajowego) via the lending bank (art. 12 par. 2 Act on Thermo-Modernisation).
  • Credit agreement. The lending bank passes the application and the credit agreement to the BGK (art. 12 par. 3 Act on Thermo-Modernisation).
  • Decision. The BGK examines the applications for subsidies in the order in which they were received. The BGK informs both the investor and the lending bank on the decision of whether or not a subsidy has been granted. If the decision is positive, the BGK also specifies the amount of the subsidy (art. 17 Act on Thermo-Modernisation).
  • Subsidy transfer. The BGK transfers the grant to the lending bank only if the works have been conducted in accordance with the project plan and have been completed by the date specified in the loan agreement (art. 19 par. 1 Act on Thermo-Modernisation). The lending bank uses the grant to cover part of the loan taken out by the investor (art. 19 par. 2 Act on Thermo-Modernisation).

Competent authority

Grants are awarded by BGK (Bank Gospodarstwa Krajowego – Polish state-owned bank) and financed from the Fund for Thermo-Modernisation and Refurbishments (art. 12 par. 1 Act on Thermo-Modernisation).

Distribution of costs


The costs of the thermo-modernisation subsidy are financed from the national budget (art. 24 Act on Thermo-Modernisation).
