ᐅ The electrician connected the live wire to the blue conductor.

Hello everyone,
We will probably be able to move into our house in the next few days and wanted to connect and test the roller shutter motors yesterday.
During this, we noticed that the electrician connected the live wire to the blue cable. My question is now (since I don’t have much knowledge about electrical work) whether this is compliant with VDE standards at all.
We have three cables everywhere: blue (live), brown (neutral), green-yellow (protective earth).
As far as I know, brown is always the live wire?!
The question is also, when you operate the ceiling light via the switch, whether the neutral wire is switched, and if there is still “power” on it even if the light is off. That wouldn’t really be safe...
I will measure again this evening to check if the live wire is switched at the ceiling light points and how the sockets are wired.
I find it hard to believe that the electrician “accidentally” connected the blue cable to live on the roller shutter motors...

I already asked the electrician what is going on.
At 4 out of 11 connections for the roller shutter motors, he apparently made "a mistake" and wired them incorrectly.
This can’t be true, can it? Overall, we have had quite a bit of bad luck with the tradespeople on our construction project, and our site manager doesn’t show up on site or check how the work is being done.
The wastewater pipes were not installed according to the plans, so we don’t have a walk-in shower with seamless tiles;
the tiler “forgot” one evening that the bathroom door opens outwards, even though we had discussed with four people in the morning what he needed to consider...
If we weren’t constantly on site, they would probably have built a completely different house...

Ok, that’s frustrating. In that case, you can only request repairs. At the end of the electrical installation, there is an inspection to ensure everything is okay. If you have a bad feeling, you can consult another electrician, explain the problem, and ask for an electrical check. They will inspect your installation again. This will cost some money, but then you will have peace of mind. Of course, they won’t detect wires connected to the wrong colors with that either. Nevertheless, I hope the rest of the process goes more smoothly for you.
It’s not that simple. First, you need to determine how many conductors are required and how many are actually installed. If, as I suspect, there are too few conductors installed (which is why the blue conductor is being used as a live wire), new cables will probably need to be installed. Whether this is still possible without major work (for example, wallpapering) is uncertain... The electrician will hardly accept responsibility for any consequential damage.
Now, everyone who keeps the DIN VDE standards under their pillow will probably want to stone me.
But if I have to choose between:
A) Opening up walls, drilling, milling, etc., and installing new wiring (with all the associated costs and possibly legal disputes),
and
B) Having everything properly tested to ensure all protective devices and residual current devices function correctly, and accepting that not everything is installed 100% according to the ideal but technically meets the minimum requirements,
then I would definitely choose option B just before moving in. You can still negotiate with the electrician afterward and reduce the bill to at least receive some compensation.
