Bafa funding for heat pumps will be discontinued as of 31.12.2020.

Yes, exactly, the parcel number of the entire meadow. And as soon as you have your parcel number, you report it to the BAfA.

Does anyone know if the approval period can still be extended? How far in advance should this be done? My BWZ is until mid-January '22, with construction starting only in August it could get tight. For the [Verwendungsnachweis] does only the heating need to be installed or does everything have to be finished and operational?

I read in the meantime about a case here that also included planning costs. Unfortunately, we also included some. In the end, is there a distinction between planning and execution costs? Or am I only entitled to the specified funding amount for the execution costs? Our notification is not here yet, but acquaintances who applied a week before us have now received the positive notification.

Application 22.12.2020 and grant notice received today. Great! Now just need to finish the objection to the increase.

Submitted on 23.12, received approval today ;) That means from now on I can officially sign contracts regarding [Wärmepumpe Bohrung Kontrollierte-Wohnraumlüftung], right?

If the total amount of the notice corresponds to what all this can/should cost, then yes.
