If you don’t have off road parking, I’m not sure Motability would lease you an EV (at the moment). Does anyone know if this is right? Also, without home charging, it would be ambitious to run an EV, not impossible mind. The i3 is different! Actually, I have a friend who doesn’t have a home charger, so maybe you can order an EV. I’d talk to Motability before you go too far down the EV route.
Like you, I wouldn’t entertain an EV without the ability to charge at home, but Motability does allow it. One poster on here (Intranicity) got a Kona EV and was relying on public charging (he lives in a flat) even though he does reasonably high mileage. In the first month or so he seemed to be managing fine. He hasn’t posted for ages so I don’t know if the novelty has worn off and he’s now finding it a faff or whether he has continued to cope fine. Perhaps if he reads this he might update?
