I think thats the route I shall go then. I will get an electrician to do the work. I have a spare cable which once fed my electric shower direct from the fuse box in my loft. I think he should be fine using that. Probably have to run in down the external wall from the loft though.
I will have to wait until I pick the vehicle up as the plan is to use one of the waterproof lockable ip rated boxes and place the charger brick in there overnight whist charging. I will have to ensure the IP weatherproof box is large enough to take it. I have seen some which are 300mm long.
I will be using the vehicle at the weekends so will have to check what fitment Aldi etc use as that would be my nearest public charger.
