Why such a big difference in actual meter reading compared to previous suppliers' readings?

Hello Ovo team :)

Nanny T is a little bit concerned and a tad unsure of what the hell to do next, so need your help.

I've just moved over to OVO (supply started 8th March), and like a good Nanny T supplied my meter readings to both OVO and old supplier. I usually let the professional gas meter man take my readings to report them back to the big guns, if i did them myself regularly he wouldn't have a job now would he? So, being fully confident in my gas meter man and his bosses, I never thought to check up on them. Just dutifully paid my direct debit every month and paid more when they upped the DD.

Now here comes the problem. My final electric reading taken by myself 7th MAR (and checked numerous times, even checking the meter serial number matches etc) is 00721

My previous supplier say my last reading by my meter man OCT 2017 is 96219 and my final estimated reading 99581. A very big difference!

I emailed them querying it and sent a photo of my meter to confirm, showing meter reading and meter serial numbers:

"My main concern is that my electric meter reading is nothing like the meter readings that have been quoted by yourselves as actually being read bi monthly. Were they actually read? As I know that utility companies only have to read meters once every year or so. And my online account gives no listed Gas readings at all either read or estimated. Your latest estimated electric reading for me is 99581 but my actual electric reading is 00721. A very big difference. I've attached my electric meter photo taken on the 7th March. I also gave OVO my Gas reading 0482965 on the 7th March too.
Thank you for getting in touch and explaining what happens next. I'm just quite concerned as to the big difference in my electric readings and not sure of what my gas is according to your records"

My reply today:

"Thanks for getting back to us about your final bill. Sorry its taken a little longer than normal to reply to you and that I couldn't reach you when I called today.

Your last routine readings were on 3 October 2017.....

We try to visit all customers at least twice per year to read your meters. in some cases its less frequent of there's been regular meter readings submitted online.

The routine readings we got on your last visit were:

Elec: 96219, Gas: 04097 (My own gas reading 7th Mar is 0482965)

I can see that the electricity reading now compared to your history is very different.

If you want to investigate whether the meter is perhaps faulty then you'd need to arrange this through your new supplier.

I would like to do more for you but I'm afraid we're not able to book appointments for supplies that have switched away from us.

If there's anything else that we can do for you then let us know."

Soooo....can you please advise what I should do next? I'm quite worried. The history on my old supplier account states that actual meter readings were taken bi-monthly which were not used for billing. Only the bi-monthly estimates (it states) were used for billing.

It just seems a little bit coincidental for a meter fault to have happened when reading myself as leaving for a new supplier. How is it possible to know if it is an actual meter fault or something to do with previous supplier? What should I do next?

Sorry for the long babble btw

Welcome to OVO!

Sounds like your previous supplier may have been estimating your usage based on an estimated Annual Consumption figure. Now you’ve switched we really need to make sure we get your opening meter readings correct. There’s more info of the usual switching process in our joining OVO Guide.

If you’ve already received your OVO opening statement, which is usually issued around 6 weeks after your switch date, we’d recommend checking the opening meter reading which should match the closing reading that’s used on the final statement issued by your previous supplier. If there is any discrepancies with your opening meter readings we may need to raise a ‘Meter Reading Dispute’ to get this corrected, although this depends on the readings being outside of a certain tolerance. Read more about this process and the time frame to get this sorted on this great guide.

Once any opening meter reading issues have been sorted, you might also want to consider getting a Smart meter installed - this will avoid you having to worry about estimated readings in future.

Hi @Transparent,

Thank you so much for your very clear & detailed reply.

I haven't a clue myself if the costs per kw will be to my advantage but I can say that my OVO DD has been based upon my old suppliers estimate of my usage next year (and of course OVO is a bit cheaper than EON hence the switch), so i'm hoping the error will be in my favour. I am assuming then, that following the outcome of the reason for the big difference that if the meter needs fault checking that OVO will look into it. Ohhh what a pallaver!! :S

"Finally, can I please point out that the gas reading you quoted for the 7th March should be 04829 (not 0482965). The last two digits are beyond the decimal point on your meter, and therefore don't form part of the reading"....ahhhh, there must have been an elusive decimal point that needs better glasses to spot! Thank you for that 🙂
