My usage as shown on the OVO website has been changed retrospectively - huh?!

I’m in the habit of cut and pasting my usage cost date into an ongoing spreadsheet. The costs for one day in December were wildly out of kilter with the rest - impossibly so - and I was about to cut and paste the data from the website to ask Ovo what that was about. Yet I now find that all of the data for December - apart from the first two days - is different from what I captured from it two months ago: It has been changed.

The three columns on the left are the December data when I captured it (and 31/12 is obviously ridiculous - even if I’d accidentally captured the wrong month, it could never be right. The three columns on the right are what the website now shows.

Anyone got any insight into what this could be about? Decidedly dubious in my eyes...

Hi @timfg

1. Do you have smart meter?

2. What page on the OVO website did you extract the data from?

It does happen that figures are recalculated if estimates have had to be used (either with or without a smart meter) or if the Calorific Value of gas is updated for example. It is not particularly unusual to be raised on this forum. 

It is difficult to be more specific in an answer to questions like this. 

The quarterly change in the Energy Price cap on the evening of 31st Dec etc can often cause strange looking readings that net out OK. I always see that on the meter reading page for my account. I think that is what you saw at the end of December. So you may see it again at the end of March. The big change looks like a correction due to the change over perhaps. 

I don't think it is anything to worry about in your case looking at the figures. The overall change for the month is relatively small, perhaps look at the net effect over a longer period. 

You could try contacting the OVO Support Team and asking for the reason in your specific case, but you may end up spending an awful lot of time if you do this. Depends on how much you want to find out. It would likely take weeks or months for OVO to get back with any account specific responses and even then it may well not give you the detailed answer you may or may not be after. 

The changing readings are simply a feature of the OVO system. 

I don't work for OVO, i am just a customer like you.

That’s interesting. If I look at Loop for one day with missing data I get 

but if I look at Bright for the same day I get 

I know that licenses differ from third parties to suppliers but this seems odd as presumably the data must be there

It depends how often each provider  retries requesting the data.

It does vary by provider. For me Loop is the worst, Bright a bit better but similar to OVO.

But for me all 3 never get all the 30min gas data consistently unfortunately on every day. 

The OVO daily reading hasn't been an issue luckily. That is fine for me.

I can reliably look at the 30min on many days just not all of them.

So take 13th Feb 

OVO daily 58.18 kWh

OVO 30min 44.21 kWh

Bright daily 43.77 kWh

We have seen this with some other customers, even for electricity in some cases.

My data from Hugo is the most reliable just not ‘in day’ available. 

Looking at the same day as the rest Hugo data shows as above and OVO as below

    @timfg perhaps vote for this as an alternative to cut and paste of data

      Incidentally, I just checked on the last few days of data from Bright and compared to the OVO data. It is exactly the same kWh readings for both fuels. As has been mentioned, I don’t use these for any billing but it’s interesting to note that they must both feed from the same source .. possibly how the data graphs on the usage page differs to billing
