ISDE: Connection to a district heating network for homeowners Grant

About this grant

The ISDE (Investeringssubsidie duurzame energie en energiebesparing) subsidy for connecting a home to a district heating network (warmtenet) helps Dutch homeowners fund the switch away from natural gas. The subsidy covers the connection of a home to a heat network outside the dwelling, after which the home is fully gas-free: heating and hot tap water are supplied through the heat network, the gas meter is removed, and the home is prepared for electric cooking (for example an adjusted meter cupboard and cabling). The page states that the fixed subsidy amount for the connection is €3,775, equivalent to roughly USD 4,719 at the stated conversion rate. An online ISDE calculator is provided to estimate the total subsidy, which may vary by case. Applicants must submit the request within 24 months of the connection to the heat network. Required documents include an invoice and proof of payment showing the connection date, amount and payment date, a copy of the heat supply agreement, and written confirmation from the grid operator that the gas meter has been removed (or a confirmation stating when removal will occur if the meter is still present). Applications are made online using DigiD. The page notes that homeowners who are members of a Vereniging van Eigenaars (VvE) with a collective heat supply do not qualify for this subsidy; those homes may instead look at the SAH scheme for rental homes where applicable. The subsidy is administered by RVO on behalf of the Ministry of Economic Affairs and Climate.

Eligibility

Open to homeowners in the Netherlands who connect their own dwelling to a district heating network. The application must be made within 24 months after the connection.

Homeowners who are members of a (mixed) Vereniging van Eigenaars (VvE) with a collective heat supply are excluded from this subsidy. Applicants need DigiD (app or with SMS verification) to apply.
