Kfw funding, change energy consultant

Hello,

I am renovating a small multi-family house with the help of KfW funding. It is supposed to become a KfW 70 house. The energy consultant must verify this at the end. Unfortunately, the current energy consultant is no longer really available due to illness. Does anyone know if it is possible to simply change the energy consultant? Can another energy consultant simply check the house for energy efficiency?

Shouldn't be a problem at all? Who puts the "stamp" on it in the end doesn't matter.
