Hello.
Connction fee Iberdrola is circa 155€
Connestion Fee Urbaser for water is circa 196€
I do not know why you paid Polaris 400€ as these are paid by the owner by direct debitb to the utility company?
We were quoted the connections would be 400€ by Polaris and we signed a form allowing them to authorise connections which they did on our behalf we paid them nothing but Iberdrola and Urbaser took the connectio fees direct from our bank.
