In Germany, its about 25% of the cars which don't have a regular parking spot only, I would be surprised if the numbers in the UK would be vastly different. However, everywhere where in-street parking is regular over night, there should be power outlets at the street side. They are quite common in the scandinavik countries, as even ICE cars used to be plugged in over night for heating the motor.
