Interesting Energy usage graph

I looked at the graph of my energy usage this morning. It claimed I used £14784 worth of gas and £40 worth of electricity in August followed by £23481 for gas and £44 for electricity in September followed by £52 gas and £34 in October when the gas was first used! November and December were relatively sensible and of course January is not yet complete. Interestingly they have figures for February, March etc so can my SMART meter really can divine what I am going to use? One would expect the soft ware ought to be capable of at least flagging up that a value is ridiculous. Come on BULB get your act together.
