Why have I been billed to an incorrect estimated opening reading - can this be recalculated?

I have recently received a statement from Ovo, with a breakdown of my usage over the last 10 months or so, and the numbers they have used are wildly inaccurate, to the point that I believe them to be charging me over £1000 too much for my annual usage.  They have also given me an estimate for next year of over £7000, meaning my energy bill would be more than my rent.  I have already contacted customer service, but I was hoping to find some reassurance here that these mistakes will be rectified.

In my previous property, I was on a prepayment meter, and would put £10-15 on each per month.  When I signed up to Ovo at the end of September last year (I had just moved in a couple of days before), I was quoted £97 per month.  I knew this was high, but I was unable to provide my annual usage numbers, so I agreed to the ‘average’ for my type of property.  I am pretty sure I gave meter readings (how else would they know what I was using without a starting number).  However, the statement is using estimated figures that are significantly different from a reading I have photos of from the 12th Oct.  I have also submitted several readings to them since.  Unfortunately, these submissions were not exactly every month.  Despite selecting the option on my account to be given a monthly reminder to provide a meter reading, I have not received a single reminder in the entire time I have been a customer, so I have only submitted half a dozen readings in the past year.  This should still be enough to work out my averages, but the statement only has one actual reading on it, from June.

I am now worrying that despite the evidence I have provided, because they supposedly don’t have any actual readings for Sep-May they will insist that I used all this energy, despite the fact that I live alone in a small 2 bed terrace, with only the boiler (currently) using the gas.  The discrepancy between the estimated 30th Sep reading and my actual 12th Oct reading is about 650 units for electric and a staggering 3,500 units for the gas.  I don’t believe it is even possible to use that much in that period of time.

I have since learned that Ovo have been fined millions of £ in recent years for incorrectly estimating and overcharging customers, so I am suprised they are not paying closer attention to how they are billing their customers now.  Anyone else having similar issues?

Sounds like we may have opened your account to an estimated reading @DanielTSTocks.

 

If that estimate was much lower than it should have been this would explain the large amount of usage charged before the first reading you gave. Best thing to do is see if you can find out the actual meter reading from the date you moved in. If you didn’t read the meter yourself, your landlord of letting agency may have listed the reading on your inventory or check-in report.

 

Once we receive an actual meter reading from the move-in date we can reverse your statement and rebill you based on what’s actually been used.

 

If you’ve checked and there’s no record of the reading on this date, not to worry. We’ll be able to recalculate the opening meter reading based on readings you’ve taken since. We need at least 2 sets of readings taken 2 weeks apart to check your average consumption and whether the opening meter reading falls in line.

 

If you haven’t already it’s worth mentioning to our Support Team that you believe your opening meter reading is incorrect. They can use the evidence you’ve supplied to see if we can recalculate and rebill you in this case.

 

In terms of your gas consumption figures it’s hard to confirm the actual usage without access to your meter reading history. Do you use gas to heat your home or just for cooking? I would say that the gas costs you’ve calculated are incredibly low for 10 months of usage if you do have a gas boiler, so if this is the case, something doesn’t seem right. Have you checked whether your gas meter is clocking in metric (i.e. metres cubed) or imperial (i.e. feet cubed)?

 

Hope this helps get to the bottom of things. Do keep us updated when you hear back from the Support Team, it will be really helpful for others finding this thread in future to see how things get worked out! :ok_hand:

Morning ​@spaldino,

 

I’m sorry to hear of what has happened here, it sounds very frustrating 😔.

 

On the Forum we don’t have access to customer accounts, so I can only speculate as to what’s gone wrong here. 

 

In my opinion, it sounds as if we never received readings, and billed the account completely on estimates. When you received your bills, the reads would have appeared as ‘estimates’ and, when you logged into your online account when you were our customer, there would have been messages telling you to submit manual readings as the meters weren’t in comms.

 

if you never gave any manual reads from the smart meters, then OVO wouldn’t have had anything to base your bills on apart from estimates. It sounds like the new tenant has immediately provided a manual read, which we would have re-billed you to. If this reading was taken manually from the meter, then it will have been an actual reading, rather than an estimate, and would have been in line with your actual usage.

 

My advice here, is to provide the correct opening reading from when you moved into the property, if you never provided this. if you took a photo of the reading when you moved in please send this to our Support Team. If you’ve already logged a complaint  then you should have received an email with the complaints reference number. If so, please reply to that email with your meter photo from when you moved in, if you have it.

 

If you don’t have a photo of the meter reading from when you moved in, I’d advise contacting the Letting Agency, as it’s likely they would have taken a reading from when you moved in. They may even have sent you an itinerary when you moved in, that contains a photo of the opening read. I’m speaking here from my own experience as a renting tenant. 

 

All in all, it sounds like the final read of your account is correct, but maybe not the opening read. Once we’ve billed you from the correct opening reading to the correct closing read, then that will be the final amount that needs to be paid.

 

If you haven’t been sent an email containing a complaints reference number then get back in touch with our Support Team and request to log a complaint. You’ll then be given a complaints reference number, and will have a dedicated Complaints Handler. OVO will have eight weeks to resolve this for you. After the eight weeks has elapsed you’d be able to refer this to the Ombudsman, but I can’t see how it would take OVO eight weeks to resolve this one for you. 

 

Best of luck, and I hope it’s all sorted quickly for you. If you get the opening read from the Letting Agent and send it to us we can generate the correct bill within minutes.

@Ben_OVO Somehow my original topic thread has been deleted? Is that how this forum works?

Overall, I believe my experience represents a chain reaction of system and process failures at OVO Energy that could be resolved at a company level reviewing its CX.

I’m certain I provided an opening meter reading. I was informed the account was closed and refunded. I didn’t believe I needed the original meter reading based on what I was told by OVO. It was then magically re-opened, with a new balance. Just bizarre. 

The fact that a person can open and close an OVO account with estimated readings without it being flagged as a problem and communicated directly, that’s a bit like setting up an Amazon Prime account without a valid card security number i.e. it wouldn’t be allowed to happen.

I wouldn’t trust the letting agency reading, since I strongly believe there is unbilled usage at the property that I was being wrongly charged for. I did put trust into the smart meter reading, because that’s what was promised by OVO (and is still being mentioned in this thread as a solution). I don’t see any point in this process so far where OVO has done the right thing. I have received a complaint reference to resolve formally.

Hey ​@spaldino

 

If you’ve asked a question that’s similar to existing questions then we’ll merge the newer question in to the existing topic thread. This keeps the Forum cleaner and all of our advice and suggestions from the community in one place! 

 

As ​@Ben_OVO has said we can’t see you’re account here as we’re just a customer forum but if you contact our Support Team they’ll be able to look into the status of the billing dispute for you.

 

When you closed your account, did you provide a final meter reading? Your previous bills should indicate whether the balance was based on estimates or actual readings. To accurately update an account and reconcile any unbilled usage, a meter reading can be used to adjust for past consumption.​

 

I’d suggest getting in touch with our Support Team and i’ve left an article below that might be helpful that covers what meter reading disputes are:

 

I hope you get things sorted!
