Energy consultant costs and services

I renovated a heating system in a rental property for about €50,000. My energy consultant is demanding a hefty €4,000 for reviewing the documents, etc. Is there a service fee schedule for energy consultants? His demands appear significantly high to me. What experiences have others had?

Not clarified beforehand? What did you sign?

Just get some comparison offers. Who’s forcing you to hire this one?
