Build before or after 01.04.2016?

So a telephone information?

No, everything is stated under KfW 153

Now I've discovered it. That wasn't there just now...

On the KfW page, however, I cannot find anything about the amount of the grants from 04.2016, only that the loan amount is increased from 50000 to 100000 and KfW 70 is no longer supported.

Exactly that. Just look under the tab 'Konditionen' and a bit further down there. It's not extremely obvious.

2016 is already a few days old and April 1st is approaching.

Has anyone taken a closer look at the KfW 153 starting April 1st?
The final conditions (interest rates) are not yet known. But even so, there seem to be some changes in the implementation and subsidies.

Subsidies for construction supervision are not possible when applying before April 2016. They will only be granted from April 2016 onwards according to the stricter KfW requirements.

We now have a first offer for:

Offer for the KfW certification of an Energy Efficiency House 55 with 3 residential units

for over 2,400 euros (net).

Has anyone made comparisons so far, so that one can better assess what is really needed and what this cost can and may be?

If your house is eligible for KfW funding, it probably makes sense to use the funding from April 1st, as my understanding is that a loan of EUR 100,000 per residential unit is granted. So far, the interest rate for the KfW 153 program has rarely been higher than that of other banks, so the chance is quite high that you can finance more cheaply than today under the current conditions of KfW.
