You must submit the application for funding in writing to the Kreditanstalt für Wiederaufbau (KfW).

  • You first need a financing partner, through whom you then submit your application to KfW. A financing partner can be a bank, building society or financial intermediary.
  • Select your financing partner and make an appointment for consultation. If you are looking for a financing partner, you can use the online consultation request on the KfW website for this purpose.

  • You complete the loan application together with your financing partner. Your financing partner informs you which other forms and documents you need for your application.

  • Conclude the loan agreement with your financing partner and start the measure. KfW will pay you the loan amount in full.
  • When you have completed the measure, you must prove to your financing partner,
    • that you have spent the money from the loan on the measure and
    • that the measure technically fulfills its performance.
