I've had a 'smart meter' installed Oct 12 and un-funnily enough, my average usage from 19kwh / day prior to this increased immediately to around 35kwh. The lowest day I've had since is 29kwh. Given our house has only 2 occupants, gas for heating, cooking etc. and we've no new appliances, how can this be explained other than bad metering or reading of the data? August - 15khwSeptember - 19khwOctober - 35kwh+ following the 'smart meter' install ???
