Another update but a potentially important one for some people.
i had a call yesterday from Motability saying that BP Chargemaster would be contacting me about fitting a fast charger at my house, which I was aware of.
But interestingly she continued saying that if Chargemaster said they could not fit a charging point for whatever reason I could still have the i3 if I wanted, because they had relaxed the rules due to more public chargers becoming available.
So basically if you thought that not being able to have a home charger fitted (eg if you live in a flat or terrace with no driveway) would exclude you from an i3 on Motability, that is now changed and you will be able to have one.
I hope this is helpful
