Apply for a loan for the energy-efficient refurbishment of residential buildings to create a KfW Efficiency House

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

• You look for an energy efficiency expert in your area on the website of the German Energy Agency (dena).
• You discuss the planning and monitoring of your refurbishment measure with the expert. This expert will check the eligibility of your measure and prepare the confirmation for the application (BzA). The expert will provide you with the identification number (ID) of the BZA (BzA-ID), which you will need for your application.
• Talk to your financing partner (a bank, building society or financial intermediary with whom you would like to take out your mortgage) about including a promotional loan. They will advise you on which additional documents are required and will submit the application to KfW on your behalf.
• KfW will check your application and inform you or your financing partner whether your loan with repayment subsidy will be approved.
• If KfW approves your application, you conclude a loan agreement with your financing partner.
• As soon as your application has been approved, you can start building work or buy the renovated property.
• Depending on the progress of the construction work, your financing partner will pay you the loan in one lump sum or in installments.
• Once you have completed the project, you must provide your financing partner with proof,
  • that you have spent the money from the loan on the planned measure and
  • that your measure meets the standard of a KfW Efficiency House.
• 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 to your loan account. This reduces your loan term.
