I've been in my house nearly 2 years and I have an economy 7 electric meter. The 'night' part of the meter hasn't moved since we've been in. I never noticed as I just read the meter when asked and I don't make a note of the numbers.
NPower have just spotted it. They've wrongly said it's the day one that's not moving so have kindly removed all the readings from my account over the last two years and replaced them with an obviously higher estimate. Yay! They've then just taken 660 odd quid from my account without warning. They haven't corrected for the overnight readings. On the statements they've described it as 'read by nPower' when they've never been to read it.
Where do I stand on this? They have no evidence that I'm not turning the power off at night and the meter reading is accurate. Obviously the day one is right and they need a kicking. They also started sending me threatening emails saying they would break in to change the meter and charge me for the bailiffs to break in. No contact prior, just the nasty email. I called them to try to book in a replacement meter install and they had no appointments. Cue a more threatening email.
