Sustainable energy investment subsidy scheme (ISDE)

This information is provided by:Netherlands Enterprise Agency, RVONetherlands Enterprise Agency, RVONederlandse versie

If you want to produce your own sustainable energy in your business premises using a solar boiler or heat pump, you may be eligible for a sustainable energy investment subsidy. The Dutch government wants to stimulate heating in a more sustainable way.

This subsidy will partly compensate for the initial investment costs of the device. The actual compensation depends on which device you purchase and its energy performance.

When do you qualify?

You are a business owner (in Dutch) with a valid Dutch Business Register number (KVK-nummer). This includes:

  • self-employed professionals
  • housing associations and homeowners' associations
  • partnerships, foundations and associations
  • municipalities, provinces and public entities as market party or as owner or tenant of (im)movable assets
  • private commercial lessors of housing or business spaces (these do not need a Dutch Businees Register (KVK) number)
  • commercial operators from abroad that want to install one or more devices in the Netherlands

You also need to:

  • install the device on premises in the Netherlands
  • apply for the ISDE subsidy before purchasing the device
  • start using the device within 12 months after receiving a decision about your application (within 24 months if you have installed your device on or after 1 January 2022)
  • make sure your device meets the technical requirements (in Dutch)


You can apply for different types of devices for sustainable energy. Conditions differ per type.

Listing products

Suppliers, manufacturers, and (building) installation companies can have their products listed with RVO on the ISDE devices list and insulation measures list (in Dutch). If your product (heat pump, solar boiler, lowemission or low-E glass, or insulation material) is listed, you customers know they may be eligible for the ISDE.

How to apply?

You can apply for the ISDE subsidy scheme (in Dutch) to the Netherlands Enterprise Agency (RVO).
