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

I found that! I now enter the reading the next day so that the reading is always dated in the past and there is no time left on that day!

However I also find that readings are not cast in stone. That is to say that if you look up the reading history that will state the readings that you have entered but OVO is quite capable of changing the date/time or reading on the bill - even after you have downloaded it!

I have a screenshot of mine in a certain date and when it arrived in paper form it was a completely different balance for that day. I submit readings too

It’s worth noting that if you have gas, the bill will update once the Calorific Value data has been factored in, which takes a few extra days.

You can mitigate this by submitting a reading on the first day of the next billing cycle.

Alternatively, the recommended long term solution is to get a Smart Meter and it’ll auto-submit at the perfect moment to eliminate the entire issue.

Very Strange,

                       Have you requested for a new Smart Meter to be fitted, I used to send my meter readings monthly on-line until I found out that Valiant & OVO had a discounted tariff for ASHP customers and I needed a Smart Meter fitting to take advantage of the Tariff, I`ve been very happy with the new meter,

If possible request OVO to fit new meter.

As said if you submit a reading on (or before) the last day of your billing period there is still that day until the end of the period - so you will always get an estimate showing for (at least) that day.

The trick is to send your reading the day after, ie on the first day of a billing period.

That way then the reading sent covers up to midnight on the last day so there is no estimate on the bill.

My case is that I have to send in the readings because I had a smart meter fitted but am told that it cannot transmit to OVO. Therefore I do not have the privileges of having a smart meter and there is no reason why they should play around with the readings as sent (See my earlier reply).

I would dearly like to know why OVO thinks it is OK to change the “readings on the bill” and even send me “corrected” bills several months later with different values. The result of this is that I do not fully trust the system but feel they may all be the same. It does rather remind me of the old joke when someone had to pay in a cheque for £0-0-0 (ie. old money and yes the cheque did, I believe, have to be sent or so the story goes!)

I have several bills where the brought forward amount does not agree with the carried forward amount on the previous bill but have tried to convince myself that the amounts do correct themselves! I do pay by direct debit!

Hi, what is ASHP?

ASHP = Air Source Heat Pump.

​@puffin could you show me photos of the meter please?

Thanks.  I have one too.  But I didn;t know about that discounted tariff!  

Now I;m locked into another tariff for a year.  Heat pumps are expensive without solar panels. :(

That’s why OVO has Heat Pump Plus. 15p/kWh for eligible Heat Pump usage 24/7/365. They’re not as bad as you think. It’s also an Add-On so you can enable it without breaking contract and racking up exit fees - you just attach it to your existing tariff.
