KfW stop! Energy consultant wants his money!

The guy has done his job. And what's there to complain about? The energy consultant has calculated the whole building for you. You only used that service in the hope of a subsidy, that's clear.

Exactly like that and no other way. No one comes up with the idea of not paying the photographer for the application photos because the company did not hire the applicant!

What on earth are you actually thinking? (...) Whoever acts as cluelessly as you do and then dares to complain about others, I don't wish anything different for them.

I can understand that you are annoyed, but it can also be phrased differently and emotions kept under control. The forum thrives on friendliness, understanding, and objectivity. In my opinion, such treatment of obvious "newbies" is out of place.

However, the request of the OP has nothing to do with being a "newbie in the forum."

Of course, the energy consultant must be paid. Whether 1000,- eur is appropriate, I cannot judge. In relation to the over 5,000,- eur, however, it sounds very reasonable. Didn’t you think about the KFW application in advance? You had to submit the application yourselves, not the energy consultant.

And if "ridiculous" for you is over 18,000 euros, then it will indeed be the 1,000 euros that I fail.

You did commission him, so pay!
