I asked the question. I didn’t say it was the case. However: Capped energy in the home after October will be 34p per kWh. Take an average EV consumption of 3 miles per kWh so 11p per mile. Petrol car say 45mpg, so 10 miles per litre @ 1.60 so 16p per mile. So yes if you always charge at home it will still be much cheaper. But if you use public chargers, in this scenario once they cost more than 50p per kWh, it’s not. Very rough mental figures used so please please don’t quibble over the detail!
It depends on what figures you put in as you say Wigwam. 3 miles per kWh is a little mean, 4 is a good average, and 45mpg is probably optimistic for petrol, however, the key for many is home charging, overnight at cheaper rates. Ev’s will work for some, and in my case if it was a question of purchasing/leasing privately and paying for a charger, I would have probably stuck with petrol.
