I have contacted Motability about the Home Wallbox Charger and have been told that from April 2020 the process has changed and that for those of us who are ordering a full EV, a Home Wallbox Charger will be provided by Chargemaster (if it’s the first Home Wall Charger).
The process that triggers the process of getting the Charger is when the dealer keys in the order the system detects that the car is full EV and you are asked if you agree to info being given to Chargemaster for the provision of the Charger.
Then Chargemaster will contact you to get the process rolling.
