I really want to buy an EV as my next car, but I live in a terraced house with no off-street parking. There is a charger down the road from me provided by Source London but as far as I can tell it would be more expensive for me to use that than to use petrol even ignoring the higher purchase costs of an EV. As you point out the pricing structure is so confusing it’s hard to know.
Add in the extra hassle of moving the car after each charge and the potential for someone else to be using the charger when you need it and an EV doesn’t seem like a viable choice. Surely suburban London should be a natural sweet spot for EVs given the types of journeys people do, but the infrastructure lets us down.
