@Elliot Never heard of anyone getting 2 chargers fitted at the same address. The charger fitting is entirely discretionary, and Motability will wash their hands of it. You can charge either car on the Ohme charger, there is no need for card swiping. You plug the car into the charger and it charges any of your 2 cars. If you want a 2nd charger, you will have to pay for it yourself One user moved to another property with no charger and asked Motability to install another charger. He was declined. One charger per household.
That’s definitely not what I was told by Motability and Ohme.
