Last time I checked the sun doesn’t shine and the wind doesn’t blow at night.

It isn't base load - it is peak load
The 18GW number comes from a report from the National Grid. The range was 6 to 18 GW if 100% of cars go electric by 2050. 6GW if charging is well managed and most charging is done off-peak and 18GW if charging is completely unmanaged. With the recent statement that future chargers will have off-peak charging programmed as the default it seems the UK is choosing the well managed option.
Where does the extra electricity come from? Maybe the UK just continues their current trend. UK energy consumption has been steadily falling since the mid-00's. By continuing to make other sectors of their economy more efficient they steady create excess capacity that can be used to charge EVs.
Or maybe nothing gets more efficient and we take the middle cause of 12 GW which is 20% of the current 60 GW. The UK would need to add 20% peak capacity over 28 years. That seems doable.
