We had our gas and electricity bills this morning. As we're with British Gas (please, no diatribes about changing supplier) the period billed includes the price rises on the 1st of March. To calculate the bill BG therefore had to estimate the readings on the 1st of March. Fortunately the previous figures and present figures were both genuine readings. I hadn't read the meters on the 1st of March myself, but as my readings are closer together than BGs (23rd Feb, 6th Mar) I can probably more accurately estimate the actual reading than they.
Of course, their estimate comes out lower than mine, meaning that according to BG I used less gas and electricity before the price rises than according to my own calculations.
To cut an exceedingly long story short, after some fiendishly complicated calculations I worked out that I had been overcharged 37p for electricity and 59p for gas (give or take a penny due to differences in rounding strategies). It doesn't sound a lot, but that
96p represents just 7 days between the 1st of March and the meter reader's figure from the 7th of March.
I'm in two minds whether or not to ring BG up and make a point about this (I'd probably spend more on the 0845 call), but the thought occurred to me that we're probably not the only ones. What if all BG customers have been overcharged? What if it's about a pound for each one of them? What an easy little money-spinner!
Hwyl!
