Joining late to the thread but hoping to get some insights. My home electricity tariff at the moment is 29,6p/kWh. Some chargers like Ubitricity are at 24p/kWh in Putney. They are at 32p in Fulham. I have been charging at the 24p Ubitricity lamppost and it works like a dream. Is there any reason I should be charging at home (involves laying a cable cover across the footpath that isn’t exactly legal)?
