Octopus go intelligent tariff for me too. Still charge @ 7p on cheap overnight electricity, for the whole house as well. Also if I plug the car in during the day it will charge at that rate out of hours when demand is light on the network. Only costs us £3.50 to top up with 50kwh charge!
Switch onto this tariff when you get your EV.
