Second time worked, thanks @

It looks to me like this meter is well past its sell-by date which might be why this is happening. I've got two options that I can think of, please consider both of them and go down whichever route you feel comfortable with.
Option 1 is that you get this meter tested with a Meter Accuracy Test and/or report it as potentially faulty. This may cause a £160 charge if the meter is found to be accurate, but you'd get that refunded if it's found to be incorrectly recording usage and the meter would be replaced. I'd recommend this route if you think it's over or under recording usage.
Option 2 is that you simply get the meter upgraded to a Smart Meter without doing a fault report. This route is much faster as the upgrade can simply be booked in and the meter swapped out for a brand new one that's basically guaranteed to not have this issue. However, you wouldn't get any refunds that may be possible with option 1 (though you also don't gamble the £160 either).
Option 3 is do nothing and leave things as they are. It's an unwritten rule that I have to provide this option (even though I don't like it!) because I've had people elsewhere in the past try to accuse me of being biased, forcing them to pay £160 fees or forcing people into getting Smart Meters. Providing this option is my solution to those naysayers, but it's definitely not the option I'd choose if it were me.
