ISDE Subsidy for Heat Pumps in the Netherlands (2026)

ISDE Subsidy for Heat Pumps in the Netherlands (2026)

More Dutch homeowners are switching to heat pumps to reduce gas consumption, lower energy bills, and make their homes more sustainable. To support this transition, the Dutch government offers financial assistance through the ISDE subsidy scheme.

For many households, this subsidy can reduce the total investment by several thousand euros and significantly improve the payback period of a heat pump installation.

In this guide, we explain how the ISDE subsidy works, how much you can receive, and what requirements apply in 2026.

What Is the ISDE Subsidy?

The ISDE (Investeringssubsidie Duurzame Energie en Energiebesparing) is a Dutch government subsidy for sustainable home improvements, including heat pumps.

The scheme is designed to make energy-efficient systems more affordable for homeowners. Depending on the type and capacity of the heat pump, households can receive a substantial reimbursement after installation.

The subsidy applies to:

• Hybrid heat pumps

• Full-electric heat pumps

• Ground-source heat pumps

• Solar boilers

• Insulation measures

For homeowners considering a heat pump, the ISDE subsidy is often one of the biggest financial advantages.

How Much Subsidy Can You Receive?

The exact subsidy amount depends on several factors, including:

• The type of heat pump

• Heating capacity (kW)

• Energy efficiency

• Brand and model

Typical Subsidy Amounts

• Hybrid heat pumps: usually €1,500–€3,000

• Full-electric heat pumps: usually €3,000–€6,000+

In general, larger and more efficient systems qualify for higher subsidies.

Examples

• A small hybrid system for a terraced house may receive around €2,000

• A full-electric heat pump for a detached home could receive €5,000 or more

Because subsidy amounts vary by model, it is important to verify whether the selected heat pump appears on the official approved device list.

Who Is Eligible?

To qualify for the ISDE subsidy, homeowners generally must:

• Own the property

• Use the home as their primary residence

• Have the system installed by a professional company

• Choose an approved heat pump model

The installation must also meet minimum energy performance requirements set by the Dutch government.

DIY installations are typically not eligible.

How Do You Apply?

The application process is relatively straightforward.

After installation, homeowners can submit the subsidy request through the Dutch government portal using:

• The invoice

• Proof of payment

• Installation details

• Device model information

Applications usually need to be submitted within a limited period after installation.

Once approved, the subsidy amount is transferred directly to the homeowner.

Why the Subsidy Matters

Without subsidies, many homeowners hesitate because of the high upfront costs of a heat pump.

The ISDE scheme helps reduce:

• Investment risk

• Payback time

• Installation barriers

Example

A hybrid heat pump costing €6,000 may effectively cost around €4,000 after subsidy.

This can shorten the payback period by several years.

Combined with lower gas consumption and rising energy prices, the financial case for heat pumps becomes much stronger.

Which Heat Pump Is Best for Your Home?

Not every home is suitable for the same type of system.

Factors such as:

• Insulation quality

• Home size

• Radiator setup

• Gas usage

• Electricity consumption

all influence which heat pump makes the most sense financially and technically.

General Rule of Thumb

• Hybrid heat pumps are often ideal for older homes

• Full-electric systems usually work best in newer or well-insulated houses

A professional assessment can help determine the most efficient and cost-effective option for your situation.

Calculate Your Potential Savings

Before contacting installers, it helps to understand:

• Your expected savings

• Estimated subsidy amount

• Payback period

• Suitable heat pump types

Using a heat pump calculator can provide a quick first indication based on your home and energy usage.

This helps you make a more informed decision before requesting quotes or speaking with installers.

Final Thoughts

The ISDE subsidy remains one of the most important incentives for homeowners considering a heat pump in the Netherlands in 2026.

By reducing installation costs and improving long-term savings, the scheme makes sustainable heating solutions far more accessible for many households.

Before making a decision, it is worth comparing systems, checking subsidy eligibility, and estimating your potential savings to find the best solution for your home.
