We have had an EV for almost a year. If you cannot charge at home, an EV will cost you more than petrol or diesel. The UK has appalling high charges for charging with public chargers compared to France. There are many excuses given whenever you mention this but there are two companies in the UK… Tesla (avg 55p)and AW energy (39p) …. Who do a reasonable price (still more than the best in France). An added 3p per mile (which will rise) improves nothing.
Slower public chargers can be cheaper but still relatively high…. Possibly slightly less than petrol.
We do not regret our EV – we wouldn’t change back, but we charge at home.
If Electricity companies charge more at home, that may change our view.
