My previous supplier provided me with a smart meter. Pity within days I could not read it. I presumed when I changed supplier it could be read electronically but no seemingly, as all my bulb readings are estimates. I have mailed Bulb but no reply. I am a lot of money in credit but do not know if that is real credit or not. In addition, my boiler is bust so want to know how much electricity we are consuming heating the house whilst we work on getting a new gas boiler.
