Take the subsidy check!


The ISDE grants subsidy for making business premises more sustainable. You can get a reimbursement when you for example invest in solar water heaters, connection to a heat network, a heat pump, small wind turbines or solar panels.


ISDE aims to make investing in sustainable heat more attractive. Through this subsidy, such sustainable investments become as affordable as assets that are less energy efficient.

Do you invest in sustainable solutions, but is the ISDE not the right fit? Take a look at the EIA en SDE++ instead.


I am driven to make an impact and optimistic in my quest for a fairer and more sustainable society. It is my ambition to contribute to the transition to a low-carbon economy and as a sustainability & innovation consultant I can give substance to this by advising innovative projects in the field of (renewable) energy, CO2 reduction and circularity on subsidy options.
