Apply for funding to replace the heating system

Anyone wishing to replace their oil, gas or coal-fired heating system or an electric resistance heating system with a climate-friendly form of heating can apply for a grant from the Senator for the Environment, Climate and Science until August 31, 2025.

  • Basic information

    What is subsidized?

    Funding is available for the installation of efficient heat generators and heating support systems, as well as for connection to a building or heating network.

    Who is eligible for funding?

    Eligible applicants are private individuals as building owners, tenants and leaseholders as well as companies that have contractually taken over the heat supply and/or hot water supply of a building (so-called contractors).

    How is funding provided?

    The funding amount is calculated in such a way that the sum of the subsidies granted by third parties and the state for the same measure corresponds to 60% of the eligible investment expenditure.

    Who is my contact person?

    The Senator for the Environment, Climate and Science has commissioned BAB Bremer Aufbau-Bank GmbH to process applications under this funding guideline.

    Requirements

    • The funding can be granted for existing buildings in the state of Bremen regardless of their type of use (residential use, commercial use).
    • Functioning oil, coal, gas floor or electric resistance heating systems (with no requirement as to when they were commissioned) or functioning gas heating systems (if they were commissioned at least 15 years ago at the time of application) can be replaced.
    • A certificate of decommissioning from a specialist company or waste disposal company must be submitted confirming that the heating system has been properly decommissioned.
    • State funding under these guidelines will only be granted if funding for the same measure is applied for and approved under the guidelines for federal funding for efficient buildings - individual measures (BEG EM).
    • Important: The application for state funding and the application for early project start must be submitted first and the applicant must have received approval for early project start before the application for federal funding can be submitted. The background to this is the change in the federal application procedure, as the date on which the project commences is the date on which the funding commitment is received from KfW. From this point onwards, it is no longer possible to apply for state funding.
  • Procedure

    • Apply for funding from the BAB before you submit your application for federal funding.
      • The background to this is the change in the federal application procedure, as the date on which the project begins is the date on which the funding commitment is received from KfW. From this point onwards, it is no longer possible to apply for state funding.
    • You will find the link to the application form under "Further information".
    • Send the application by post or e-mail to the BAB or submit the application directly there (Domshof 14/15
