For the last four months my Ovo bill notification emails have said
“Just to let you know, we've updated some of the charges shown in a previous statement as we now have accurate energy use information for this period. Your new bill shows the updated charges so you can see clearly what’s changed.“
I always provide a meter reading on the 10th of each month just as we were asked to do when we joined nearly two years ago. Now with the new billing system it sends me a first attempt at the monthly bill a week after the 10th, then the following month always seems to revise it and add a bit more on. What’s going on with the system? Why doesn’t it just accept my meter readings on the 10th and work out my bills from that? Some months have even been revised up and down three times. I can no longer work out what the correct bill is for a given month, as the email attached version is different from the one I download later from the site, which then changes again the following month.
