However, the key is the capability of the incoming supply to the house. Is there a maximum rating for a domestic dwelling or can you have as much power as you want by agreement with the power distribution company?
Depends on the DNO, but they are usually very keen to provide their customers with as much power as they need. There are many domestic customers with high power demands even without EV charging.
For domestic EV charging I really can't see a problem with overnight top-ups, this idea that you have to get a full range charge every evening is a canard, most cars only do a max of 30 miles a day, an amount easily replaced between 22:00 and 06:00.
