but here in The Netherlands installing a home charger (11kw) is at least 2000 euro which is difficult to earn back by driving electrically.
Really doubt that.
Did you already get an offer from a company?
How long is the distance from you "main eletricity point" to the wallbox?
You can buy cheap 11kW wallboxes for ~200-250€
If you have a solar system, then the "special ones" which are managed by your solar input are ~700€.
Mounting that to a wall i like mounting a picture. Not hard at all.
The only thing which can be tricky is "making the hole for the cable".
Making the final electric connection is the only thing which has to be done by a professional, as I guess you also need to register it with your electric company.

Wallbox - 269€ (https://www.technishop.de/wallbox/technivolt-technivolt-100)
30 metres NYM-J 5×4 mm² cable - 130€ (https://store.besserladen.de/p…itung-nym-j-5x4-mm%C2%B2/)
braker unit ~70€
Then you only have to pay for the electrician to connect a few cables and install the breaker.
Should be EASY under 1000€
