  • Your measure must meet minimum technical requirements
  • Your measure must cost at least EUR 2,000 net, including incidental costs


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 a consultation. If you are looking for a financing partner, you can use the online consultation request on the KfW website for this purpose.
  • During the consultation appointment, your financing partner will check whether your planned measure meets all the requirements and whether you are creditworthy.
  • 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.
  • Your financing partner submits the completed loan application to KfW. KfW reviews your application and decides on the funding.
  • You will then receive notification from your financing partner as to whether your loan with repayment subsidy will be approved.
  • 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
    • a confirmation from the manufacturer or supplier that your measure technically meets the performance (specialist contractor declaration).
  • You submit this evidence to your financing partner.
  • Your financing partner checks and confirms your evidence and forwards it to KfW.
  • If KfW has also checked the evidence, you will receive the repayment subsidy as a credit.

It is best to seek advice from an energy efficiency expert before submitting your application for funding. Small and medium-sized enterprises (SMEs) can apply for subsidies for consulting from the Federal Office of Economics and Export Control (BAFA) in the program "Federal funding for energy consulting in SMEs".
