Please see my earlier review about the bad install experience. I have now moved on 4 days and the charger has worked for 3 of those days! (Currently not working). After the first day I sent an email about their app which was telling me on one occasion that I had been charging for 1 hour and it had cost me over £9! That's despite the fact that the app showed that I only paid 15p per kWh. Then the next two days it said that the charging was free. On the third day it didn't charge despite showing the blue light. I await a call from the engineer but so far I am not impressed and wonder if I have made a mistake going with this company.
