A year and 3 months ago, I had a smart meter installed. I was on an Economy 7 Tariff because of my Storage heaters. I had a few problems with my Smart Meter because it was set up incorrectly (My off peak usage was being charged at the peak rate and vice versa). After a month of testing and complaining E.ON fixed the problem and assured me that everything was now correct. I thought that things were fine since then.

This brings me to last month. On my account, I was £159.94 credit. On the 7th of November, my account was charged and credited over 20 times leaving me £193.29 debt.

E.ON didn't notify me of why they did this. When I enquired, the response was: "I have had a look on the account and there is a note on there from the compliance team. It states that the account was rebilled for the following reason > Worked account as part of OFGEM Price Cap Compliance to correct tariffs if they are not compliant to the account set up. Tariff changed from invalid ECO7 to ECO10 version as meter is E10, ensured account is on correct NEXT_FLEX version as of 01/04/23 and rebilled accounts on correct tariff(s)".

I tried to get this resolved but to no avail. The best I could get was £30 compensation but this still leaves me in debt.

E.ON admitted that they made a mistake, they also acknowledged that I was assured things were correct after the problem I had with my Smart Metre. On top of that, it feels like they tried to sweep it all under the rug by billing me without notifying me why or saying that there was an issue with my Tarrif.

I didn't ask to be changed to ECO 10. I didn't know that they had installed an ECO 10 meter. They have just gone ahead and changed me to ECO 10 now and backbilled me for the last 12 months on this new tariff. I don't see why I should be liable to pay for their mistake.

As E.ON said there is nothing more they can do for me, I'm considering going to an Ombudsman. However, E.ON have said they haven't done anything wrong, stating that what they have done is within "OFGEM backbilling rules".

Thanks for taking the time to read this.
I feel like they have handled the situation in a crooked way.

Please can anyone advise if I have a case against E.ON?

@LimeFoot

if you have been billed even incorrectly I don’t think Eon are incorrect to correct the billing.

However, if you can show definitively that you should have been on Economy 7 then things are different if they’ve rebilled on an E10 basis.

presumably smart meter readings are available and have been used to carry out the rebilling. I feel that you should be entitled to see that data in full which would then allow an assessment to be made of what the billing would be if it were done on Economy 7 times and prices.

But beware, there’s no guarantee that would be to your advantage is there? Just because the account has swung from credit to debit doesn’t mean the earlier balance was correct. Also is the new balance to the same date as the previous balance - are you comparing two periods of different lengths?

in reality your issue will need a lot of work to resolve involving total access to your readings at certain times over the whole period. We can’t see your data so can’t advise you with any confidence.

one issue is whether you pattern of consumption was geared to E7 or E10 timings. Another is whether going forward, you would prefer to be on E10 or E7.
