EV Chargers Remote from house

GHEC

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.

    because you can't just bond stuff together from different installations (could cause some nutty problems with PME at least).

    Although we've been interconnecting different PME installations for years - e.g. by bonding shared metallic water pipes in terraced houses - and the results haven't always been disastrous. But certainly not ideal, I'd agree.  Also the other charge points would in effect be extraneous-conductive-parts as far as each installation was concerned (they'd certainly be vulnerable to carrying diverted N currents), so you'd be looking at PME sided bonding conductors for each charge point's c.p.c. - which might not be attractive ether.
