Total registered vehicles in UK , [ cars & small vans ], is about 32,000,000 .
Averaging that lot out over low rate home chargers & commercial charge units , allowing for grid loss & AC to DC charge rate loss would total up to something like well over 200GWh load if they all plugged in at once .

It's true that current generation capability does not meet the requirements for a large increase in EV use.
However, it must also be considered that - why would electricity generators produce more if the demand is not there?
A snapshot of the last 7 day demand for the UK shows a peak of just over 43GWh, and a low of 20.5GWh. There is no appetite for an increase in generation, so it is not done.

It is also a dangerous model to assume that all cars would charge at the same time, and all draw the maximum current available.
If every ICE car in theUK was to attempt to fill up at the same time, there is not the infrastructure to cope with this.
Electric Vehicle charging is not an 'all at once' situation. There would be a spread of vehicles charging, vehicles charged and vehicles in use - just as there is with ICE vehicles at present.
