ISDE

ISDE is a grant scheme for business users and private homeowners who invest in energy-saving assets. Business users can apply for ISDE grants for investments in heat pumps, solar water heaters, and small-scale wind turbines. For private homeowners, ISDE grants are available for a heat pump, a solar water heater, various insulation measures, a connection to a district heating network, and an electric cooking facility.

For private homeowners, the ISDE grant can be applied for after making an investment in a heat pump, a solar water heater, various insulation measures, a connection to a district heating network, and an electric cooking facility. This applies to the primary residence of the homeowner (commercial landlords fall under business users).

If the ISDE grant application demonstrates that eligible equipment has been installed, the ISDE grant amount will be deposited into the account. Here too, the amount depends on the equipment in which the investment is made.

If you, as a private individual, would like to apply for at least € 2,500 ISDE grant on a heat pump or solar boiler of at least € 7,500, Ignite Group can arrange this for you. Please feel free to contact us via the contact form!

An overview of the types of investments that are generally eligible for the ISDE scheme:

• Heat pumps: Grant for the purchase of air-water heat pumps, ground-water heat pumps, water-water heat pumps and hybrid heat pumps that are used for space heating or for the combination of space heating and hot tap water;
• Solar boilers: Grant for the purchase of solar boiler systems that use solar heat to heat water, which can contribute to the reduction of the use of gas or electricity for hot water supplies;
• Biomass boilers and pellet stoves: This category has been removed from the scheme in some cases, but in the past biomass boilers and pellet stoves that met certain emission requirements were eligible for a grant;
• Connection to a heating network: Private individuals can receive a grant for the costs incurred for connecting to a heating network, which can be a sustainable alternative to individual heating systems;
• Insulation measures: For private home owners, the ISDE can also offer grants for insulation measures, such as roof insulation, cavity wall insulation, floor insulation, facade insulation and high-efficiency glass;
• Ventilation with heat recovery: In some cases, investments in ventilation systems with heat recovery (WTW) may also be eligible for a grant.

As a seller of an energy-saving product or material, you can continuously submit a proposal for the relevant list of the ISDE grant. We can advise on this or submit the full proposal.

To increase the chance of an ISDE decision, it is advisable to take the conditions and requirements into account during your quotation phase. That is why it is good to have Ignite Group screen your investment plans and quotations prior to awarding the order. The form of financing (own purchase, financial lease or operational lease) is also relevant for those who are eligible for the ISDE applications.

Further conditions change regularly. Our regulations experts are aware of all current changes that apply to applying for an ISDE grant and are happy to inform you about this during a no-obligation introductory meeting.

The ISDE is a multi-year scheme that runs until 2030. Applications are possible from January 3 to December 31, 2025.
