EV Chargers Remote from house

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.

  • Before panicking, does each house present as having a TNC-s earthing system - and if it does, as above, they may be better supplied as TT  (SWA with PME proteciton of the armour, but stopping there) If the houses are fed from different substations then it could get quite messy.

    Generally inspection and maintenance will need to be agreed, maybe even in the deeds anyway, as would supplies from many houses out to a cluster of garages, or any other shared facility, though that is a more common situation, or indeed who cuts the grass around the things.

    You may need to organize the chargers as a number of distinct islands.

    I suggest this perhaps means separated TT earthing arrangements (meaning no simultaneously-accessible exposed-conductive-parts between installations, and also suitably separated below ground as per IET CoP for EV Charging? But that's not an 'island'.

    This is an electrical island: www.electropedia.org/.../display, i.e. based connection to power sources, not connection of earthing arrangements.
