Flickering room lights and occasional total power loss. Possible causes?

not really, they just need to give one of their expert's opinions. Who do you think the balance of probability favours, an experienced expert or you?

What wattage would that imply?

Not sure yet as I'll have to stand there for ages to let the disc spin a few times, time it, and extrapolate that over a year (or 10!).

But, my annual bill is only around £300. So let's say the "unused" quantity equates to 1/10 of my total electricity usage or £30, then over 10 years they'd only be liable for £300. I doubt they'd even pony up for a brief to go to court for that sort of claim. Unless they want to make a point of course.

There is a flaw in your calculations. Your bill comprises two parts: the standing charge and the unit charge.

You would have to pay the standing charge no matter how much or little electricity was used, so your deduction can oonly be calculated on the unit charge.

Thanks for the link, some useful info there.

Interestingly the suppliers solution to seeing if the customer is due a repayment for the meter reading wrongly is to wait another year with the new meter fitted and see if there's a difference from previous year/s! Really bloody scientific. Because we all know that everyone uses exactly the same amount of electricity year on year don't we? Bloody mugs!
