Wat is de SLIM scholingssubsidie?

The Investment Subsidy for Sustainable Energy and Energy Savings (ISDE) is a government program designed to help Dutch businesses transition to cleaner energy sources. If your company is considering investing in sustainable energy equipment, this subsidy could cover a significant portion of your costs.

The ISDE supports investments in hybrid and air-water heat pumps, solar water heaters, and small-scale wind turbines. For wind turbines, the subsidy covers approximately 20% of total investment costs. Heat pumps and solar systems receive fixed or tiered amounts based on their specifications and energy performance.

With a total budget of €550 million in 2025 and €511 million in 2026, this program represents a substantial opportunity for businesses looking to reduce their energy bills while meeting sustainability goals. The investment not only lowers your operational costs but also helps decrease your company's CO2 emissions, contributing to the Netherlands' broader climate objectives.

Who Can Apply?

The ISDE is open to all business entities operating in the Netherlands. There are no restrictions based on company size or industry sector. Geographic requirements are straightforward: your sustainable energy measures must be installed in the Netherlands, and your business must be based or operate within the country.

Eligibility Criteria

  • Measures must become operational within 24 months of subsidy approval
  • Installation must be completed by a certified construction installation company
  • The device cannot have previously received subsidies or tax benefits such as the Energy Investment Allowance (EIA)
  • Application must be submitted before signing an agreement

How to Apply

Applying for the ISDE requires careful preparation and timing. Before you begin, gather documentation including quotes from certified installation companies, and technical specifications of your chosen equipment.

The application must be submitted before you sign an agreement with your installation company. This sequence is crucial and non-negotiable. Once approved, you have 24 months to complete the installation and make the equipment operational.
