KfW grant for replacing a single window?

Hello everyone,

with the abundance of information on the internet, I am currently a bit confused. The following situation: In our single-family house from 2002, we want to replace an old "normal-sized" window with a new floor-to-ceiling one with RC2 and thermal insulation. In addition, an extra window should be installed where there is currently no window at all. Can this small measure be subsidized, for example, with [KfW 430]? Or do you already need an energy consultant for this? How much does it cost approximately? Total costs about 3000 euros.

Tips from firsthand experience would be helpful.

No, the volume is too low

Thank you already for HilfeHilfe. Is that too low for KfW430 or in relation to the costs of the energy consultant?

You will probably realize even without an energy consultant that replacing a window is not enough to bring the house to a KfW efficiency house standard. And if it could happen by chance because your house is already in good shape, the required measures would probably be somewhat too costly for just a window replacement.
