Costs for testing and proof provision KFW55 vs. KFW40

Hello dear forum,

I have been reading for some time and have already asked one or two questions.

Today I have the following question.

Are there cost differences between the certification "KFW55" and the certification "KFW40"?

Whereby I am not talking about the reference value method for "KFW55", but already with "invoice".

Thank you very much.

Are there cost differences between the certificate "KFW55" and the certificate "KFW40"?

I am not sure if I understand your question correctly. If it refers to the costs of the accompanying expert (must have), the latter charges a higher invoice for Kfw 40 accompaniment than for Kfw 55 ;) Rhineland greetings
