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?

     

    Submit your reading on or just before the date on your bill. An email or text reminder may suggest entering it the day before to make sure it’s received on time. If you enter your reading a little early, we will estimate your usage from when you submitted the reading until the statement date, so it should be accurate.

     

     

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

     

    Each time you enter a meter reading on your online account, we recalculate your account balance to reflect your latest usage costs. Typically, the balance updates immediately, but it may take up to 24 hours in some cases. Before submitting your readings, check your balance to see if it has been updated. If the balance in your monthly summary is an estimate, you can get the accurate balance by submitting another meter reading.

     

     

    How are my estimated readings calculated?

     

    If we use an estimated reading on your monthly summary, it will come from the last actual reading you provided and your Estimated Annual Consumption (EAC). This is how we estimate what your reading will be. If you notice any inaccuracies, you can submit an accurate reading to adjust for any overestimations or underestimations.

     

     

    What’s the best way to avoid estimated statements?

     

    A smart meter sends readings every half hour or daily. This ensures we always have an accurate reading by the time your monthly summary is ready. You won’t need to read the meter yourself, and you’ll get more accurate billing and usage information on your online account or the OVO app, which you can download for Android or iOS.

    Good Morning,

    Thankyou however this begs the question “How long does it take for the Billing team to adjust the system” as this has been going on for more than 4 months.

    Apologies if this question has been raised by others before me but I am always puzzled by the readings OVO have used to calculate my monthly bills.

    On the 19th day of each month, I input my gas/electricity readings religiously via the portal but when I receive my bills, OVO always add 5KW to the electric reading and around 4kw to the gas reading I have given them.  I cannot understand why the opening reading on my bills are always the estimated ones instead of the ones I have given OVO.

    This has been the situation since OVO took over from SSE.  I have tried to contact customer service on many an occasion to get an answer but each time come up with a blank.  I’ve been told my calculation day is the 19th of each month hence why I give my readings on this date.

    If anyone can explain this billing puzzle then great as I always feel I can’t trust the accuracy of my bills and before you ask, NO I don’t want to change to a smart meter.

    Hi @newjerseyminx ,

    Quick question, but why are you refusing Smart Meters? They are ultimately the easiest solution to this exact type of issue.

    After researching this, it has been suggested that a reading the day after your billing date is best for a manual submission. This mimics the smart meter which sends readings just after midnight. 
    What the OVO system appears to do is add an estimation to any readings on the last billing day, assuming it needs to finish that days usage. 
    There has been an update for the suggested date for readings to reflect this

      The advice/trick to avoid a small estimate at the end of your billing period is to submit the meter readings on (the morning of) the day AFTER your billing period end

      That reading then gets attributed to the last day of the billing period, so no estimate.

      eg. Mine ends on the 23rd so I sent my gas meter reading on the 24th. no estimate.

      (My current billing period, 5-½ days in, does not show an opening figure yet, and won't until I send in another reading).

      I said, Hey - Watts going on.

        Brilliant!  I will try sending my next readings in on the morning of the 20th May then check what’s been used when I receive my next bill.  Thanks

            Not sure why this is an idea … but when do you send your readings @Rita Meredith ?
