Subsidy for insulation
A subsidy makes insulation cheaper. The main scheme is the Dutch government's ISDE. Many municipalities also have their own scheme.
What is the ISDE subsidy?
The ISDE (Investeringssubsidie duurzame energie en energiebesparing) is a Dutch government scheme run by RVO. If you own an existing home that you live in yourself, you can get back part of the cost of insulation.
You can get a subsidy for cavity wall insulation, floor and crawl space insulation, roof and loft floor insulation and facade insulation, among others. The amount depends on the type of insulation and the number of square metres. Combining two or more measures often gives a higher amount.
New in 2026: if you combine insulation with energy-efficient ventilation, there is a subsidy for that too.
Please note
- Insulate first, then apply
- Apply within 24 months of the insulation work
- The insulation must meet the RVO requirements
- You can only get a subsidy once per type of insulation
- UF foam applied from 1 April 2026 no longer qualifies
