Random smart meter readings caused billing issue?

Hi 

I enter my readings monthly both gas and electricity manually. For some reason yesterday I had a smart reading applied to my monthly readings which is over 14000, whereas the actual reading on the meter is approx 11560. This has clearly provided incorrect billing details as I’m sure you can imagine and from a monthly use off approx 100 this month it’s shot up by 3000. A false reading. A clear error. 
 

from what I am aware I don’t even have a smart meter and have manually inputted readings for over 3 years now. 
 

I have checked online and it states my meter isn’t working on smart mode which again begs the question where this incorrect reading has came from 
 

having called OVO , no one could explain and the person said ‘the meter must have had some sort of fit’ how that’s a suitable response is beyond me. they adjusted the reading to the correct one but again a 14000 odd reading is now evident again today from ‘another smart reading’ so basically it was a waste of time. 
 

it’s soul destroying having to waste time proving readings whereas this is an issue with OVO. I guess back on the call tomorrow. 
 

has anyone had issues like this previously? 
 

really disappointing

Folks,

engineer attended yesterday for a site investigation. 
confimed the recorded readings at OVO were well off , as per my understanding of it prior to his visit, he said he had not seen anything like this previously. Readings were over 3000 out. 
 

the old meter was removed and replaced with a new smart meter. The old reading of 11625 was recorded on his system and on a sticker  next to the new meter. 
 

he said the old one was decommissioned and the new one would be registered to me on the DCC. 
 

to this point today, I have had no random smart readings lodged against my account 

 

hopefully the correct final reading of 11625 will be used by OVO  against the new meter starting at 00000 and not the incorrect 14000 odd readings , but we shall see what happens I guess as I’ve lost confidence in this whole situation, just hope it doesn’t get worse introducing a new  meter but shall see

While you’re waiting for something to happen, there is a little utility that works with SMETS2 meters and, I think, also worked with at least some SMETS1 meters. All it does is query the information that DCC have about your connected devices. It would be interesting to see what it turns up, if anything: https://homebrew.n3rgy.com/. Enter your MPAN and tick the tiny confirmation box before clicking Check meter.

I have done as you suggested , I can screen shot the info and post ? Excuse my ignorance but there isn’t anything that I shouldn’t be posting to do with the results is there ? 
 

an overview; 

Communication device notes a ‘warning meter connection under system can be unstable’ 

 

IDH notes ‘warning display firm ware is older than expected’ 

 

I don’t have an IDH for info want there when moved in 

 

gas proxy function notes ‘device configuration has not been completed’

Well, that’s encouraging - I think. I wasn’t sure whether the utility would be able to detect the meter at all. 

You can happily copy and paste the report from below “Errors indicate real issues” to the bottom. Once pasted here, replace the last four digits of the GUIDs and of the MPAN with ****. The MPAN is uniquely linked to your address, so anyone knowing it may be able to find out where you live. The GUIDs are the globally-unique MAC addresses of the devices’ network interface cards, so someone savvy with the right software could theoretically be able to connect to them, although I doubt they’d be able to get past DCC’s authentication barrier unless they happened to be in your back yard.

That’s brilliant news ​@callumrust, thank you for keeping us updated. The billing team will estimate the period with the out of line readings to the usage shown on your new meter. 

 


How do I book a Meter Accuracy Test (MAT)?


Completed a ‘Creep Test’ and seen a possible fault? The next step would be to book in a ‘Meter Accuracy Test’ (MAT), by contacting our Support Team.

 

As the MAT involves an engineer visit, there’s an upfront charge to get this arranged, which will be reimbursed if a meter fault is confirmed. A meter is considered faulty if it’s clocking at least 2.5% faster or 3.5% slower than it should. It’s worth considering all other possible causes for a usage spike before booking in this appointment as we can’t guarantee the results, and the cost of this test won’t be refunded if the meter is clocking within the above tolerances. If the meter is found to be faulty, we’ll replace it and re-calculate all the statements issued since the meter fault began. These statements will be based on your average usage, or your usage clocked by the new meter.

Seems the comedy roadshow continues …….

 

email from OVO  today asking to show meter reading and meter number and account has been adjusted to shown£400 debt based on the fraudulent 14000 reading.

 

just aswell I sceeen shorted my reading history, as again fraudulently it’s been adjusted to make the 14000 (incorrect reading) look correct , again just an absolute nonsense 

 

the engineer even noted the meter reading when removed it clear as day , but OVO still persisting with the BS reading of 14000 , I really wonder if anyone has any sort of idea what’s going on at OVO

One question that I would be asking is how a smar meter fitted on 29/07/2025 with a zero reading can possibly be sending Smart a reading of 14015 only 23 days later?

To me it seems pretty obvious that it’s an error and something/somewher has it down as starting at 14000 rather than zero.

If the new meter started at 00000 there is no way that you could have used that much power in 23 days.

Maybe use Live Chat and send them that image of the meter readinsg lable.

Edit to add:-
I note those screenshots were from yeaterday.
Is it still showing the same thing today or has it changed again?

It could be that what you were/are seeing is an intermediate stage in an ongoing correction.
You can sometimes see thing like that as they happen with the “live Balance” online, whereas with traditional style billing you wouldn’t see anything until it was all done.

Morning ​@callumrust, I hope you’re well.

 

Sorry to see what’s happening here. To confirm, it’s most likely that the new meter details have not yet been updated on your account, and the old meter details are still showing. When a meter is replaced it can take up to six weeks for the new details to be updated on the account as, during this time, data flows are passed to and from the Industry before the details are amended on the account. This process can take up to six weeks , however is normally a lot quicker.

 

My recommendation here, as ​@Nukecad has advised, is to get in contact with our support team. Send them the photo of the red label that you sent in this thread, and also a picture of the front of the new meter, clearly showing the meter serial number. At the very least, they’ll be able to put the account on a billing hold whilst the new details are updated. Hopefully they may even be able to update the new meter details on your account immediately. As soon as the meter details and readings are updated, your new reads will show on your account, and the balance will be rectified.

 

Let us know how you get on.
