Step-by-Step Guide to Applying for the ISDE Subsidy with Thuiseco
Unlock financial support for your insulation project with Thuiseco’s step-by-step guide to the ISDE subsidy. The ISDE (Investeringssubsidie Duurzame Energie en Energiebesparing) in the Netherlands offers homeowners, small landlords, and VvEs (associations of owners) subsidies for energy-saving measures like insulation, helping you save on costs while improving your property’s efficiency and comfort. Thuiseco makes the process simple, guiding you through each step to ensure you secure the funding you’re entitled to.
What Is the ISDE Subsidy?
The ISDE subsidy is a Dutch government program that encourages energy-efficient upgrades by providing financial incentives. As of May 2025, it offers subsidies for insulation measures such as cavity walls, floors, roofs, and lofts, with rates ranging from €5 to €10.50 per m², depending on the measure and material used. Bonuses are available for biobased insulation (up to €1.25 per m² extra) and for combining multiple measures (e.g., insulation + HR++ glass). Applications are submitted through the RVO (Rijksdienst voor Ondernemend Nederland) within 24 months of installation.
Benefits of the ISDE Subsidy with Thuiseco
- Cost Savings: Cover up to 30% of your insulation costs, saving you hundreds to thousands of euros.
- Energy Efficiency: Reduce energy bills by up to €800 per year* with proper insulation. *Source: Milieu Centraal, based on €1 per m³ gas.
- Sustainability Bonuses: Extra funding for using Thuiseco’s biobased materials like EcoGrass or hemp fiber insulation.
- Increased Comfort: Insulate your home to eliminate drafts, cold spots, and moisture issues.
- Hassle-Free Application: Thuiseco supports you at every step, ensuring a smooth process.

Follow these simple steps to apply for the ISDE subsidy with Thuiseco’s guidance. We’ll ensure you meet all requirements and maximize your funding.
Step 1: Check Your Eligibility
- Property Type: You must own and live in the property (or be a small landlord/VvE with at least one owner-occupier). The property must be in the Netherlands.
- Installation Date: Insulation must be installed after April 2, 2020, and you must apply within 24 months of installation.

- Certified Installation: The insulation must be installed by a certified company—Thuiseco meets all RVO requirements.
Thuiseco Support: We’ll assess your property for free to confirm eligibility and recommend insulation solutions that qualify for the ISDE.
Step 2: Choose Your Insulation Measures
- Single Measure: Insulate cavity walls, floors, roofs, or lofts to qualify for base rates (e.g., €10.50 per m² for cavity walls, €8 per m² for roofs).
- Combine Measures: Combine two measures (e.g., wall insulation + floor insulation or insulation + HR++ glass) to unlock higher rates and bonuses.
- Biobased Bonus: Use Thuiseco’s biobased materials (e.g., biobased PUR foam, EcoGrass) to qualify for an additional €1.25 per m².
Thuiseco Support: We help you select the best insulation options to maximize your subsidy, such as combining measures or using biobased materials.

Thuiseco Support: We ensure the installation meets all RVO standards, and we’ll take photos during the process (required for your application).
Step 5: Gather Required Documents

- Invoice: A detailed invoice from Thuiseco, including installation date, surface area (m²), Rd-value, and material type.

- Fill out the ISDE application form, uploading your invoice, payment proof, photos, and Thuiseco’s declaration.
- Submit your application within 24 months of the installation date.
Thuiseco Support: We’ll review your application documents before submission to ensure accuracy and compliance, increasing your approval chances.
Step 7: Receive Your Subsidy
- The RVO typically processes applications within 8–12 weeks.
- Once approved, the subsidy is deposited directly into your bank account (amounts vary based on measures and materials used).
Thuiseco Support: We follow up on your application status and assist with any additional requests from the RVO, ensuring you receive your funds promptly.
