My new bulb bill shows £91 of energy usage so why has my bill went up to over £400 per month?

Hello I got “the letter” about a month ago saying that my bill was going up from £325 to over £400 per month but when I checked my bill this month it’s saying I have only used £91 of energy. Can anyone help with this please?

Hey @NicolaH Thanks for your post

Your recent readings are less than previous estimates which is why your latest bill is cheaper however historically you use more. We feel based off the latest readings we can return you to £329, would be happy for us to return this back?

Did you put on £325 per month?
If so. That’s a bloody lot. I thought my usage was high.
