I'm currently working on a new housing estate and looking at different solutions for providing EV chargers.

There is a small cluster of houses with allocated parking spots off to one side. The client is keen to serve the EV charger at each spot from the respective house. 

The client will managing the land at the rear of the properties so ducting supplies wouldn't be an issue. However I feel a little uncomfortable with this approach and would prefer to provide a landlords feeder pillar and provide billable charging stations. 

Is there any regulatory requirement that would prevent serving the EV chargers from each house? Granted there may be physical issues with cable size and being able to terminate at the consumer unit.
