I Had my EV charger installed and then a week later, new smart meters were put in. As the ones BG put in when I was with them, never ever sent a reading.
New ones work perfectly and a soon as I Got the car I moved onto the eon next drive tariff, who I’m now currently with. So Until you get smart meters capable of sending readings every 30mins you’ll have to remain on the normal tariff your currently on.
They also said my display would not work but I changed the prices to a dual tariff on it and it works perfectly with cheaper rates between 12am and 7am.
