At the same time, the net metering scheme will definitively end on 1 January 2027 — making 2026 the most favourable year for solar energy investments. In this guide, you will find all current subsidies, exact amounts, and application procedures. Updated on 1 June 2026.

ISDE 2026: The Most Important Subsidy for Homeowners
The Investment Subsidy Sustainable Energy (ISDE) is the central subsidy scheme of the Dutch government for homeowners. In 2026, the total budget amounts to €500 million. The application is submitted via Mijn RVO using DigiD authentication.

Heat pump subsidy 2026
The ISDE subsidy for heat pumps is calculated based on a base amount, the capacity, and an energy label bonus:
- Base amount: €1.025 per installation
- Per kW capacity: €225
- Energy label bonus (A+++): €200 extra
- Minimum subsidy: €500
- Maximum air-to-water heat pump: €2.900
- Maximum ground-to-water heat pump: €4.500
An average air-to-water heat pump of 5 kW with an A+++ energy label yields: €1.025 + (5 × €225) + €200 = €2.350 subsidy.
Insulation subsidy 2026
For insulation measures, a subsidy applies per square metre. Important: if you implement two or more insulation measures within 24 months, the amounts are doubled.
| Insulation measure | Subsidy per m² | With combination bonus (×2) |
|---|---|---|
| Cavity wall insulation | €5,25 | €10,50 |
| Facade insulation (exterior) | €20,25 | €40,50 |
| Floor insulation | €5,50 | €11,00 |
Calculation example: 60 m² cavity wall insulation + 80 m² floor insulation within 24 months = (60 × €10,50) + (80 × €11,00) = €630 + €880 = €1.510 subsidy.
Ventilation system subsidy (new in 2026)
New in 2026: a fixed subsidy of €400 for the installation of a ventilation system. Condition: the ventilation measure must be combined with at least one insulation measure in the same application.
0% VAT on Solar Panels: A Hidden Subsidy of 21%
Although there is no direct purchase subsidy for solar panels for private individuals, a 0% VAT rate has applied since 2023 for the supply and installation of solar panels on homes. This is technically speaking a 21% subsidy — with an installation of €5,000, you save €1,050.
- Supply and installation of solar panels on or near homes
- Home batteries in combination with solar panels (as a single system)
- Private individuals and small business owners for the home
⚠️ Net Metering Scheme Ends on 1 January 2027
This is the most impactful news for solar panel owners in the Netherlands. The net metering scheme — where you can fully offset electricity fed back into the grid against your consumption — definitively ends on 1 January 2027.
| Until 31 December 2026 | From 1 January 2027 | |
|---|---|---|
| Exported electricity | 100% offset against consumption | Minimum 50% of the basic supply tariff |
| Financial benefit | Full value | Approx. 50-60% of supply price |
| Impact on payback period | 6-8 years | 8-12 years (depending on tariff) |
Conclusion: those who install solar panels in 2026 will still benefit from the full year with 100% net metering and all future years under the new scheme. The payback period has never been more favourable.
