What's important to the grid is the input. Your 6,250 Amps for the
chargers will be split into chunks of about 200 Amps per bus (at about
600 volts, IIRC), by the distribution network. It will come into the
site at about 120 Amps per feed at 11kv.

Is 11KV the standard voltage for distribution within UK cities? I wonder
why they chose that particular value. Just curious...

If you check, there is a whole network of different standard voltages
starting with the 400kV supergrid, right down to the 415 Volt 3 phase
plus neutral feeder that runs under or over your street, with branches
off to give a single phase 230 Volt supply to your house or flat.

240V isn't it or did it get dropped down at some point?

Quite a while ago.
