What is the ISDE subsidy?

HR_Installatietechniek-Blog-ISDE_subsidie

The heat pump subsidy is a financial contribution you can request from the government when purchasing a heat pump. This makes the switch to sustainable heating more financially attractive. The subsidy is called the Investment Subsidy for Sustainable Energy and Energy Saving (ISDE). It is intended for both private individuals and business users.

Want to know how to apply for the subsidy? Read our step-by-step blog: “How to Apply for a Heat Pump Subsidy.”

The ISDE scheme encourages the use of sustainable energy and energy savings. It contributes to the energy transition and reduces CO₂ emissions in the Netherlands. Hybrid heat pumps are also eligible under the ISDE scheme. Certain conditions apply, such as the type of installation and energy performance. Check in advance if your system qualifies.


What are the conditions for the ISDE subsidy?

You may be eligible for the ISDE subsidy if you meet the following conditions set by the Netherlands Enterprise Agency (RVO):

1. A Completely new product

The heat pump you purchase and install must be completely new at the time of purchase. It must not have been used previously, including as a showroom or demonstration model. Second-hand, refurbished, or previously used heat pumps, regardless of condition or year of manufacture, are not eligible for the subsidy.

2. Thermal capacity

The heat pump may have a thermal capacity of up to 400 kilowatts (kW) per individual installation. If multiple heat pumps are connected and function as one installation, such as in an apartment complex or larger home, the total combined capacity must not exceed 500 kW.

3. Application

The heat pump must be used for space heating and/or domestic hot water (e.g., showers and taps). Other applications, such as heating swimming pools, industrial processes, or cooling only, are not eligible.

4. Energy label

To qualify for the subsidy, the heat pump must have at least an A++ energy label. This label indicates very high energy efficiency according to European standards.

5. Dutch residence

The heat pump must be installed in a residence in the Netherlands. Foreign or non-residential buildings are excluded.

6. Installation and application period

  • The installation must be performed by a certified installation company. This ensures quality and prevents safety risks.
  • You may only submit a subsidy application once the installation is fully completed. The system must be operational and all related work finished.
  • The subsidy application must be submitted within 24 months of the installation date. If you wait longer than two years, you lose the right to the subsidy, even if you meet the other requirements.

Conclusion

The ISDE subsidy makes purchasing a heat pump financially attractive for both individuals and businesses. By meeting the requirements — such as a new installation, the correct energy label, and installation by a certified installer — you can receive up to 30% of the costs back. This contributes to a more sustainable Netherlands while saving on your investment.
