The first I knew is when I looked on my Eon Next app and saw I had been billed over £1300 for electricity. This statement appeared within a day or two of my normal monthly statement (which I hadn't yet received) and I figured that this statement was just that.
On reading the statement, which was just for electric, I then saw all the charges that had been re-applied for electricity used over the past year. These were then counteracted by a corresponding amount of reversed account charges.
I was able to simply look at my previous account balance at the top of the statement and subtract it from the new balance at the bottom of the statement to see what I had actually been charged against this statement. My new balance under normal circumstances should have been the sum of my opening balance and my monthly direct debit as there was no new usage recorded since my last statement. My actual balance was £2.29 more after taking into account the re-billing and the reversed charges.
So, this all worked out in my favour and to be honest, even if it was a few pounds the other way, I would have just accepted it.
A couple of things though...
I have smart meters and even if the odd reading isn't pulled, I submit a manual reading within a day or two. Why should there now be a discrepancy between the original billings and the recalculated ones?
Why isn't there some correspondence sent prior to the surprise statement alerting the account holder and to explain what has taken place and why?
I found it easy to work out as the new billings and reversed charges were all on the same statement so I wasn't left with a huge credit or debit balance at the bottom to get me excited or worried. I recall someone getting these reversed charges before they were re-billed for the original usage and immediately trying to claim the big credit balance at the bottom of the statement before being disappointed by customer service.
I now know that if I get a statement re-billing me without reversed charges on there to balance it out, or indeed a statement with reversed charges on there but without some re-billing charges, to hang fire for a day to see if another statement appears to even things out a bit before calling customer service.
Anyway, it's good to have experienced something that can cause unnecessary worry for some but I'm still baffled as to why these re-calculations have had to be done when I have smart meters and pay by monthly direct debit.
I'm an Eon Next dual fuel customer with no particular expertise but have some time on my hands that I am using to try and help out a bit.
