Below, you will find an overview of different subsidies and loans for residents, employers, and companies.
Environmental Subsidies
Environmental subsidies and loans are offered for different purposes or purchases and can come from a national, provincial, and municipal level. Let's start at the national level.

Dutch Government
The Dutch government finds climate change one of the most challenging problems of our generation. Therefore, it aims for a strong and sustainable economy to secure a future that is circular, climate neutral, and free of fossil fuels.
Central Government
With the Investment Subsidy for Sustainable Energy and Energy Saving (ISD), you can request an allowance for insulation practices such as cavity wall insulation, roof insulation, HR+++ glass and triple glass, as well as floor insulation.
Additionally, it’s possible to request it for certain sustainable warmth techniques like a new heat pump, solar boiler, and connection to the district heating system.
Homeowners and owner associations can apply for both the subsidy and loan with a low-interest rate to better insulate their homes.
If you are planning to insulate your home, you will be able to pay the 9% btw-tariff (instead of 21%) for labour costs tied to installing insulation materials to floors, walls, and roofs in homes older than 2 years.
