i was checking on line for cheaper gas/electricity,how do we know what our yearly kwh is,also to put your yearly cost in is i think far from being correct,theres the vat,standing charges,how do i work out these kwhrs,all i can give is the opening meter readings for a year ago and the 12 month closing readings,im sure i would be more convinced of a saving if kwhrs could be worked out from these readings i can give,why dont the utilitiy firms ask for these instead of all the,unnessary
