The power company have my meter reading history going back years as I’ve been with them a long time and I sent them a photo of the reading when I noticed the discrepancy.That is possible that the digits have moved when the meter is removed from the wall , but only energy providers should be doing this. Looking at your readings it has gone back.
Do you have any past billing with the (original readings) if so take a picture plus the reading showing now include the meter serial numbers in picture and on your bill.
Having said all this they should have actual past readings anyway
They kept asking me for a photograph of before the work but neither the housing association or the contractor have one and I pointed out to the power company that I don’t regularly take photographs of my electricity meter. They insisted they needed a photograph and closed the investigation but citizens advice and consumer advice Scotland both say that my meter reading history should be sufficient evidence.
