The EV Charger will be connected direct to your consumer unit. So because it is not a standard 2.5 cable there will need to be a much thicker cable run to the unit. I also had to have the main fuse changed to a 100 amp as my property only had a 60amp fuse. That was done by another company. So the answer to your question is no, You will need to connect to the consumer unit. Don’t panic these guys are used to hard setups they do these everyday. They can sort it.
