EV charging provision as part of new build planning permission?

The average consumption of all the cars in the country is not a diversity you can apply to a single street supply Andy.

Of course not - I wasn't suggesting otherwise - the DNO's don't lay cables into individual homes now based on a 1kW or 2kW assumption, but on the individual max demand (e.g. 80A or 100A) - similarly they don't allow much diversity down a short street. But as you get further out there are considerable savings to be had compared with the assumption that every house is going to need 10kVA or whatever simultaneously - especially if the bulk of EV charging can be co-ordinated - e.g. via smart meters.

 

They will want to charge at home because it is considerably cheaper.  

:

Everyone in some streets tends to be salesmen who drive a couple of hundred miles a day at maximum speed. That is why the infrastructure costs must be included, because the moment it doesn't work the builder is in trouble for non-compliance with the planning conditions.This is a serious charge and could result in him having to update everything at his cost.

You must have some very strange sales people in your area - I've never come across a 'Salesman Ghetto' with hundreds of nothing but salesmen in the same neighbourhood. Come to think of it I've never regarded as sales peoples as the types preoccupied with minimising the cost of motoring either. In any event such situations must be very rare - I strongly suspect developers would just design things as per-normal and if there were any chance of being forced to pay for an additional infrastructure upgrade in future, just take out insurance against the unlikely event. (Or possibly more likely just write into the contract that they're not to be held responsible for such things.)
