Just think if eon "mistakenly" took an extra penny from every customer in every direct debit...that's a lot of free money at the end of the year.

And how many people would complain about a few pence, let alone even notice it?

Insignificant and pointless I would have thought, especially when they just add a tenth or two of a penny to the cost of 1 kWh and they'll be reaping it in every hour of the day and night.

@JimL I have exactly the same error in basic arithmetic on around 20% of my bills. The rest of this thread seems to miss the point. I've raised it with E.ON Next and they tell me that their system is automated and not prone to errors.They also say this issue has not been raised before. I don't think it results in incorrect amounts being billed. It just makes it impossible to verify the amount being billed. Nothing to do with rounding, smart meters and all the other things mentioned. It's a simple error in arithmetic that a 10 year old could correct.

@houghtonj957 That statement " system is automated and not prone to errors.They also say this issue has not been raised before" raises 2 questions in my mind
1. The incorrect result of the equation clearly shows an error - so the 1st statement is fatuous.
2. I raised this issue when I started this thread. I also raised it again last week (5/8/24) as a complaint because EON fabricated a previous meter reading (plucked out of thin air) AND got the calculation wrong (again) to boot. So the 2nd statement is a blatant LIE! If you speak to them again about this and they tell you "it's never been raised before" ask them to check complaint ref - 1571464.
Also, the equation error DOES result in incorrect amounts being billed. 2p in my case. Irrelevant you say. The advisor told me EON have 3 million customers. That amounts to £60,000 per month at 2p per customer

I suspect that if they use a rounded reading one month any inaccuracy will be countered the next or later subsequent months. All the factors in the calculation are static, apart from the readings and the calorific value. If the readings can’t cause any repeated error that only leaves the calorific vale. Now this does drift as the mix of gas gradually changes over time but probably individually computed to each account as the reading dates will differ, although smart meter reads will be more standardised.
I, and many others, are not sleeping too well at the moment, but in future I may return to thinking about this topic as it will likely send me off quite quickly, despite the heat.

@houghtonj957 @JimL

The figures are correct for my kWh gas consumption as can be seen over the last 7 months on attached picture. Gas smart meter reads are recorded by myself accurately (to 3 decimal places) just before midnight on the day the reads are pulled on schedule. The bills themselves do not show this degree of precision although I suspect that 'rounding' is only done when the final kWh figure is produced and the accounts themselves only show integer values. Even so my billed kWh usage over the last 7 months have matched very very closely with the kWh that I have calculated. The very slight variance is undoubtedly due to the CV being shown to only 1 decimal place on our bills although I suspect that a higher degree of precision is used. Unless you carry out the same degree of precision that I have sadly done 😉, there will be ups and downs each month on your kWh calculations.
