I would hope they would bring some documentation about this in the form of a webpage, leaflet, etc But i presume it’s still a trial in progress and maybe it’s a reason for not adding an influx of EV’s on to the scheme until they have ironed out any creases.
For the manufacturer to be responsible for installing the home charger is great, but unless all manufacturers are going to use the same contractor, or at least a majority of them, then installation times will be greatly varied. It also leads to a number of unanswered questions i.e when do you enter your pin, at installation of the charger or handover of the vehicle? and if the latter can you still pull out of the lease after installation of the charger? I’m afraid it opens more questions than i can answer.
