I was staying in Newcastle and I booked into Jesmond Dene House as they showed electric car charging. I was first a little shocked that they charged £1 per kWh but doubly so when the car reported that I received 47kWh but the charger reported 54. Is this normal? Am I being charged for the electricity being used by the charger with some energy losses? I can imagine the outcry were a petrol station with leaky hoses charge for 50 litres whilst only delivering 40.
