Burglary protection: Missed KFW funding deadline.

Hello, last year I applied for a KFW grant for burglary protection in our house. Here, since the funds for 2016 were exhausted, a conditional approval was given. Therefore, I waited in 2017 for a renewed notice from KfW, but never received one. The measure had already been carried out after receiving the provisional approval at the end of 2016. Unfortunately, the craftsman’s company only issued the invoice about a year later. I then submitted this immediately. Unfortunately, KfW is now rejecting the payment of the grant with reference to the six-month deadline for proof of the measure. Does anyone have experience with this situation or an idea how I should proceed now? I am grateful for any tips, thank you very much and best regards.

Count it as experience. You won’t achieve anything at KfW Bank.

Simple rules, simple rejection. Lessons learned.
