The government is increasing the budget for heat pumps. Discover how you can get up to €3,500 back. The Investment Subsidy for Sustainable Energy and Energy Saving (ISDE) has been expanded with additional funds for hybrid heat pumps. The subsidy now amounts to up to €2,850 for a hybrid system and up to €3,500 for a fully electric heat pump.
Applications can be submitted via the RVO website. Please note: the budget is limited and subsidies are allocated on a first-come, first-served basis. Therefore, apply as soon as possible to benefit from the increased budget for 2026.
What is the ISDE and who is it for?
The ISDE (Investeringssubsidie Duurzame Energie en Energiebesparing) is the central subsidy scheme of the Dutch government for homeowners who make their home more sustainable. It contributes to the purchase of heat pumps, solar water heaters, insulation measures and connections to a heat network. The scheme is intended for homeowners — tenants are not eligible, although your landlord can apply for a subsidy. The aim is to lower the financial threshold for switching from gas to sustainable heating.
How much subsidy do you get for a heat pump?
The amount of the subsidy depends on the type and capacity of the heat pump and on the energy label of the device. As a guide for 2026:
- Hybrid heat pump: up to around €2,850. A hybrid system combines a heat pump with your existing central heating boiler and is a relatively accessible first step.
- Fully electric heat pump: up to around €3,500. This replaces your gas boiler entirely and offers the highest savings on your gas bill.
A more efficient device with a higher energy label generally yields a higher subsidy amount. Because the exact amounts are reviewed annually, always check the current figures on RVO.nl before purchasing.
Conditions to keep in mind
- Recognised device: The heat pump must appear on the official list of eligible devices maintained by the RVO.
- Professional installation: The installation must be carried out by a recognised installation company. Do-it-yourself installation is generally not eligible.
- Application deadline: You must submit the application within a set period after installation, so don’t wait too long.
- Homeowner: You must own the home in which the heat pump is installed.
Applying step by step
- Choose a recognised heat pump from the RVO list and request quotes from certified installers.
- Have the device installed by the professional company.
- Collect the invoice, proof of payment and the meld code provided by your installer.
- Submit your application via Mijn RVO, logging in with DigiD.
- Receive the subsidy in your account, usually within a few weeks of approval.
Combine measures for maximum benefit
You get the most out of the ISDE by combining a heat pump with insulation. A well-insulated home requires a smaller, cheaper heat pump and delivers lower energy bills. In addition, more and more municipalities offer extra local subsidies on top of the ISDE, and a reduced VAT rate applies to insulation work. Check with your municipality which additional schemes are available.
Make your home even greener by switching to a sustainable energy supplier. Vandebron connects you directly to a Dutch wind turbine or solar farm — new customers currently receive up to €420 welcome discount.
Frequently asked questions
Can I combine the ISDE with other subsidies?
Yes. You can combine the ISDE with municipal subsidies and an energy-saving loan. You can also submit multiple measures in a single application.
Is a hybrid or a fully electric heat pump better?
A hybrid heat pump is a more accessible and cheaper first step that works alongside your boiler. A fully electric heat pump replaces gas entirely and offers the greatest long-term savings, but works best in a well-insulated home.
When does the ISDE budget run out?
The budget is allocated on a first-come, first-served basis. Historically the budget for heat pumps runs out faster than for insulation, so applying early in the year is wise.
