I mentioned in another post that I would contact HSE regarding any issues reported to them arising from loss of neutral and EV charging points. They have responded and confirmed that there has been no incident reported to them. However, they were made aware of a small number of situations that were a result of poor or no load management. I should point out that this is HSE in Northern Ireland.
I am never confused, ( at work)!!! I cannot speak though for other DNOs,and different areas have different policies. North Norfolk may have different policies to central London. LPN, London power networks, SPN, South power networks and EPN, Eastern power networks have slightly different policies because of historical issues. EV chargers on the public highway, ( and certain other areas) would not be offered a PME terminal.
On consumers property, PME is allowed though unlikely, as the resistance of a rod would be virtually impossible to obtain, so we are looking at TT or 1/1 transformer. Apparently there is a new "gadget" which disconnects the L/N/E but I have not looked into it, I cant see how that would work, normal voltage drop on the network would carry over to the car body and people would get tingles. But I am open to stand corrected on that.
So, in answer to your question, PME on the driveway, depending on loadings/resistance
