Agree with others, you current housing situation is your biggest barrier. You menton about moving house, when are you expecting this to happen. If it’s within 3 months time for example, you could speak with Motability and ask them to delay installing the charger untill you have moved. The other thing to think about is the delivery time for your new vehicle, may well concide with you moving home. The only other option is to extend your current lease untill you move home, before ordering an EV.
If you plans are to move house withing the next 12 to 18 months, you could again extend your current lease or consider a hybrid as you next car.
