I give meter readings each month, why is my bill still based on estimates?

Why, when I faithfully provide meter readings on time, each month, does OVO still give estimated readings on my bills?

Meter readings, usage and estimates

 

If you haven’t had smart meters installed, we’ll send you a meter reading reminder a few days before your monthly summary is created. The easiest way to submit these readings is on the ‘Meter readings’ page of your online account or OVO app (download for Android or iOS):  

 

When’s the best date to submit a reading for my monthly summary?

 

The best date to submit your reading is on or just before the date shown on your bill - the email or text reminder you receive may suggest you enter this the day before to make sure it’s received on time. If you do enter the reading slightly early we’ll only estimate your usage between the date you entered the reading and the date the statement was generated, so it should be fairly accurate.

 

When I enter my reading how long does it take to update my balance?

 

Every time you enter a meter reading on your online account, your account balance is recalculated to include your usage costs up-to-date. The balance will usually update instantly although it can take up to 24 hours. It’s worth checking the balance before submitting your readings, so you can easily check that the balance has updated. If the balance show on your monthly summary is estimated, you can always check the accurate balance by submitting another meter reading.

 

How are my estimated readings calculated?

 

If we ever use an estimated reading on your monthly summary, this is calculated based on the last actual reading you gave and your Estimated Annual Consumption (EAC) to give us an idea of what the reading is likely to be. You can always correct any over or under estimated readings by submitting an accurate reading.

 

What’s the best way to avoid estimated statements?

 

As a smart meter can be programmed to send us a reading half-hourly or daily, we can always be sure we’ve got a reading on the date your monthly summary is issued. This will mean no more worrying about reading the meter manually and more accurate billing and usage information on your online account or OVO app (download for Android or iOS.

Hey @billgemmell,

 

Sorry for the issues you’re having, 

 

As you have switched to OVO recently the large estimated bill may have been due to a read dispute, this is when an initial reading is used that is an estimate which is not in line with the other ‘actual readings’ from a meter. 

 

This can be raised by OVO, or the previous supplier you have switched from. Once this is raised we can place you on a billing suspension, and a direct debit review suspension meaning your direct debit isn't increased. 

 

 

If it was an out of line estimate mid billing cycle. Then every read submitting subsequently will alter the estimated annual consumption and predicted direct debit. There is a live billing system so when you submit a meter reading your account balance will change accordingly. I’d strongly suggest getting a smart meter installed so your readings are sent across automatically. 

 

 

Hope this helps.

I have raised the issue with OVO on two occasions and despite assurances that there is an error in the estimated use and a further assurance that the DD would not increase, OVO increased the DD yesterday.

The actual readings that I submit to OVO appear to be ignored as these readings would confirm that I will never use the energy that has been estimated by OVO.

Hey @billgemmell,

 

That sounds very frustrating, I’m sorry to hear this. 

 

Please contact the Support Team who will be able to submit an actual reading on your behalf. It may then be flagged and go to the billing team to be authorized and added to the account. You can contact them via web chat. 

 

Customer Support will also be able to put your account on a direct debit review suspension for 3 months until this is resolved. 

 

Hope this helps.

Have you put in a complaint over the last 3  months?

I am new to OVO and from my short time with them I am convinced they are the worst energy supplier in Britain

3 months ago they told me that due to my electricity usage IO would be in deficit for over £16000 pounds

They have done me a favour and reduced the estimate to only £4500 meaning that they want the DD to go  from 206 to 597 a month

I live in a modest 3 bed house and despite sending them monthly readings they refuse to listen to me and have told me lies that the amount will not increase and the estimate submitted was in error

Has anyone had this problem?

Hi yes my bill seems to be never ending , a new price everyday. I have waited over 6 weeks now for 4 outstanding email replies and nothing! I'm changing supplier it's a joke

According to Ovo Q&A you should send your meter readings on the last day of your current billing period it then takes 2 days to generate the actual bill for that period. With my last energy company on a 12 week billing period you would get your bill by email. You could then send in your meter readings then and you would get your new bill sent instantaneously to your email 

why does it take Ovo 2 days to generate your bills after submitting your readings on the last day of your current rather than instantaneous as with my previous energy company

Not sure of your previous supplier @Pilgrim2 but besides double checking, gas costs have to be calculated after readings are taken to take account of the caloric value. These figures aren’t published by the gas transporter until after each days supply. 
That’s probably a key reason

In my case O am an electricity customer only no gas involved so you would expect your bill automatically as I did with SSE Hydro

OVO do have what they call ‘live billing’ so you can see your usage and costs immediately online
