I'm with octopus and I got a smart meter installed on 11th November. I've just got an email this morning with a weekly bill from the 11th - 18th (first week of having meter installed) and it absolutely doesn't match my smart meter at all even with the 5% VAT, I have attached photo of the smart meter with the amount I have used in total since the meter was installed 9 days ago. My account is now in the minus. I'm really confused and feeling stressed about it. Does anyone understand and can advise? Tried calling but they aren't open until tomorrow and then won't be able to ring until my lunch break. The bill seems very high, we are definitely not using £44.38 a week and it's so much more than the smart meter is showing.
