Pluginvest's quote includes
technical audit
installation works
charging station
the (mandatory) AREI inspection
In 80% of home installations, the installation works are already included in the basic package.
Basic package:
15m cabling
1 wall penetration and addition of an automatic and differential protection in the fuse box.
You will receive confirmation that all works are included after the technical audit has been carried out. (In many cases this can also be done remotely.)
Any additional works usually involve additional cable length and are charged via fixed cost-per-meter rates. Your agreement will be requested in advance for this.
