I believe some are 69p per kW like ionity EV’s aren’t great in the winter when you’ve got to heat the battery and for those who are only doing short journeys could see less than one mile per kw.
Ionity are 69p for anyone not driving an affiliated vehicle or paying a monthly membership, then it drops to around 30 or 35p if I remember correctly, I don’t use them so not sure on their pricing.
Your last paragraph about EVs in winter is just wrong ?♂️ complete made up nonsense…. ? I’ve had an EV since 2014 so so that’s 8 winters worth of driving and we’d use my car before taking the wife’s ICE.
