Random smart meter readings caused billing issue?

Mon 18th August my gas usage on thr OVO app is showing as 11.6 Kw but has been charged at over £1820 this is for 1 days useage obviously a massive billing error best way to get this corrected please

What you describe doesn’t sound right at all. Although it may just be a glitch in the app that won’t actually affect your bill.

Could you post an image of the error please, so that we can see what you see and advise from there what may be going on.

If we can work out what has happened then we may be able to put your mind at rest here.
Or at the least if you know what may have caused it then it will be easier for you to explain that when you contact customer support.

is it from the usage page like this:

Or is it from “Billing>Charges and payments>See details” like this one:
 

Or maybe you are meaning something else?

Usage is 11.61kwh charges £1,821, photo 2 readings for 18th Aug seem out of order,

thanks for your help really worrying 

Thanks for those, as you say it’s obviously wrong.

I’m sure that you’ve spotted where, and how, it went wrong:

That’s obviously a rogue reading from who knows where; real meter readings don’t jump backwards like that.

(At a wild guess I’d say the error is probably from DCC (the metering company) and that’s a reading from someone elses meter that has somehow been sent to OVO as being yours).

However there is no need to panic here.
Your monthly bill will use the first reading of your billing period subtracted from the last reading of the billing period.
eg. This is mine from 24 June to 23 July, you can see it only uses the first and last readinsg to get the usage for the month:

So unless your billing period happened to be the 18th to the 19th of each month -which it isn’t - then that error will not actually get billed for.
(It’s only showing on your current Live Balance on the app, the Live Balance can sometimes show odd things that you wouldn’t see with ‘monthly-only’ billing).

As today is the last day of your billing period then your billing tomorrow should show your correct use and cost using the 25th Jun reading subtracted from the 23rd Aug reading.

So I’d say wait at least until tomorrow, or Monday, to see what your actual bill for July-August says then.

If you are still worried then I’d contact support using the Web Chat so that you can upload those images, pointing out that obvious reading error.

Thats excellent thanks very much makes sense about 1st day and last day of billing period any problems will do online chat as you suggest i noticed on around the day the issue occurred a neighbour  had some work done on their smart meter this maybe produced the spurious reading 

​@John lloyd-Williams  one more thing.

i also noticed that your current billing period seems to be a day short, 25th - 23rd?
At least that’s what your screenshot says.

So I’ve editied the above to say probably wait until Monday 25th Aug to see what your actual bill says then.

Ok thanks

Isnt that because today is the 23rd current billing period until today ?  

Ahh, that may be why.

(My own period is 24th to 23rd so would be saying 23rd today in either case)

So it's still Monday that you need to check your bill for the full month.

Really helpful thanks for your assitance 👍😃
