Hi Neil, Do you know why during the 17Jul-16Aug period. AGL charged 331kwh + 221.9kwh for a total of 552.9khw. However, according to my own ledger on the 18th July the meter read's 39434.8 and on 19th August the meter read's 39763.So (39763 - 39434.8)/32days to work out the daily usage (10.25kwh). Then 10.25 x 31 = 317.9kwh and its no where near the 552.9khw figure. Any ideas? Thanks
