Had other information on this: namely that the info from the GU was that the property ID/number is sufficient. So that is "nonsense" accordingly and an energy consultation is needed.
I would think: both. For a receipt stamp, it may be sufficient initially just to be able to designate the object. But when an application processing begins, the processor first looks at the completeness of the documents and will issue a reminder if they are incomplete. You will probably be given a deadline to remedy the incompleteness. If this deadline then passes unsuccessfully, the consequence of a rejection notice must follow – and then inevitably it comes into play that your receipt stamp date loses its value. As far as I am correct with this assessment, it follows: if you submit the application at the end of January, the processor can only start processing six weeks later and grants you two weeks to improve completeness, then you must be able to deliver by the end of March. You will not have to wait any shorter for an appointment with the energy consultant than the processor needs time – your house should therefore already have been planned. Thus, since the press release of the termination, the traffic light is already dark yellow for those builders who have at least arrived at the airport building now. For you, with still nothing in hand, I see the plane taking off without you. Still, you will not be able to terminate a construction contract for a KfW55 house without compensation. So either you can afford to upgrade to KfW40 or build KfW55 even without funding. I would advise you, even in the interim phase "KfW55 no longer funded, but not yet legal minimum standard," to already go for KfW55, since it has already become the de facto market standard. That is why the funding can now also be stopped: because the purpose of funding, to accelerate the energy-policy-desired action of builders, has already been achieved. THAT is/was the reason for the funding – not as pocket money for you.
