The repayment grant is NOT paid out but shortens the term of the loan.
That is correct. However, you have the option to apply to your bank, for example for the repayment grant and special repayments, so that the term is reset to the original and the monthly burden is reduced.
The grant for involving the energy consultant comes after submitting the invoice from the same, I think the processing time will be similar.
Very important, one should only submit these at the end, when all invoices are available. I called there about this yesterday because we had received the first partial invoice from our expert.
