Hi,

 

I have a smart meter why do I get estimated readings on my Bill? I thought a smart meter would know my correct readings.

Got a smart meter installed but noticed we’ve estimated your usage on your latest monthly summary? There’s a few reasons we could be using estimated readings when it comes to your bill, even if you have a smart meter.

 

It could be something as simple as not having the smart meter set up to send half hourly or daily readings. It’s worth checking your meter reading schedule with the Support Team, and get it updated if it’s set to a monthly reading. This will help prevent estimated bills as well as giving you a better view of your usage too. For more on this check out our handy topic below all about meter reading schedules:

 

 

If you know you have these set up and it’s not the issue, there’s a chance we could be experiencing communication issues with your meters.

 

The first place to check what’s going on with those smart meters is your online account or OVO app (download for Android or iOS). You’ll know something’s up if you see this message on the Homepage:

Exact wording may vary

 

This message will appear if we haven’t received a reading from your meter as expected for at least 5 days. Hopefully this is just an intermittent issue and the meters will get back in touch with us soon. In the meantime it’s worth submitting a meter reading a few days before your next monthly summary is due. 

 

To take a reading you’ll need to go to the meters themselves (this won’t be viewable on the In Home Display unfortunately).

 

For SMETS1 ‘Secure’ smart meters:

 

There’s a slight difference between the the S1 meters we installed. To take a dual (day/night) reading for Secure Liberty 110 S1 smart meters (which are designed to work best with storage heaters), press 9 on the meter’s keypad. If you’ve got a Secure Liberty 100 S1 smart meter, press 6 to confirm the Day and Night meter readings (pressing 9 will show the reading if you’re a single rate member with this meter).
 

For SMETS2 Aclara, Flonidan, Honeywell or Elster smart meters:

 

  Aclara (Elec) / Flonidan (Gas) Elster (Elec) / Honeywell (Gas)
Reading the meter
  • Elec: Press A three times until TOU Rate 1 appears.
  • Gas: Press C to wake up, then C to access the menu. Use B to scroll and C to select the reading option.
  • Elec: Press the top button once or twice
  • Gas: Press the circle button once or twice

 

You can then enter this reading by clicking ‘Send reading’ on the Homepage message or by clicking on the ‘Meter Readings’ menu option:

 

Exact appearance may vary

 

Here you’ll be able to see the last reading we received and the date this was sent to us. Unless you’ve sent a manually reading already, this will be a good indication of when your smart meter lost communication with us. Click ‘Send electricity reading’ and you’ll be taken here:

 

 

It’s worth checking the reading you’ve taken against the last reading (it shouldn’t be a lower number - unless your meter’s faulty!) You can then type today’s reading into the box or boxes (for an Economy 7 meter) provided:

 

 

Exact appearance may vary

 

Click ‘Next, send a gas reading’ to send the reading from your other meter (if this applies to you!). If you refresh your Homepage you’ll notice your balance will update to include the up-to-date usage costs. 

 

Hopefully this will be a temporary communication blip and we’ll be able to recover the communication without any further action. If it’s been a few weeks and you’re still noticing the smart meter message on your Homepage it’s worth carrying out a smart meter health check for your meter type below and forwarding the results on to our Support Team for further investigation:

 

SMETS1 Secure Smart Meter Health Check

SMETS2 Smart Meter Health Check

 

 

Fingers crossed those smart meters will be back in touch soon and you can continue enjoying all the great benefits of going smart:slight_smile:

Thank you for the response.

 

Unfortunately I have done this 4 times and gotten nowhere.

 

At the end of my rope now to be honest. Causing a lot of stress

Does the billing say it’s used actual readings or estimates?

Sometimes a Smart Meter reading doesn’t get to OVO for some reason.
Sometimes it might not be sending them, sometimes it is sending readings to the metering service, but they are not then getting passed on to OVO.
https://www.ovoenergy.com/help/article/what-to-do-if-your-smart-meter-isnt-sending-readings

Just a suggestion that may or may not work for you:

If your Smart Meter is currently sending daily readings then contact support and ask for that to be changed to half hourly readings - making that small change might just shake things up a bit, enough to put it back on track..

Hi thanks for the reply.

It's an actual reading from the electric meter. 

Spoken to them again this morning and apparently it's flagged on my account as an issue but the accounts team "have a backlog and rectifying the bill wasn't a priority". It's been escalated to high importance and the person I spoke to has also passed it to the complaints team.

Hopefully it will be sorted soon

the accounts team "have a backlog and rectifying the bill wasn't a priority".

Amazing that anyone in a customer support role would actually say that.

If it’s true then somebody should give the ‘accounts team’ a swift kick up the backside, and remind them that for customers getting the correct billing would be seen as a basic essential, and the highest priority to fix if it isn’t correct

I know - couldn't believe it when I got that response. Apparently of the previous person I spoke to had flagged it as highly important it would have been looked at sooner. It's been a month and still not done. Must be one hell of a backlog

I’m curious  , how I can use 8 to 12 kWh per day and then suddenly jump to 17.58 kWH yesterday? I was at work all day, only home in the evening.. No heating on… minimal hot water usage … 

Can someone explain to me please? To me it looks like I’m being charged for gas i’ve not used… 

Ta Much 

8 May 2024 11.91 kWh
9 May 2024 11.83 kWh
10 May 2024 9.75 kWh

Do you have a Smart Meter for gas, or are you sending manual readings?

Is that 16th May figure an actual reading or is it an estimate?

If it's an estimate then in some circumstances they can sometimes be well out like that, I've had that issue myself in the past with estimated gas usage.
(Generally why it happens with some estimates is known, but the circumstances and details are complicated to pin down and fix - it is being investigated).

If you already have a smart meter for gas then it may simply be that that days reading was not received at OVO for whatever reason, in which case they would estimate (possibly by too much) for that day until they did get a new reading at which point the estimate(s) would be corrected to your actual use.

If you have a ‘manual reading’ meter and not 'smart' then one way you can have an influence yourself on reducing incorrect/too-high estimates is to send more frequent meter readings.
Weekly at least, and I'd suggest perhaps daily for the first week or two to imitate what a smart meter does.
I have done that myself with my manual reading gas meter and can confirm that it works to reduce the estimates.
I’d also look at/request having it changed to a smart meter: https://www.ovoenergy.com/help/article/how-to-get-a-smart-meter

Thanks for your response

I do indeed have a smart meter, which isn’t very smart ;) .. It often doesn’t pick up readings and I have to send a manual one in… It’s quite variable on sending readings and not sending them. 

The one from the 17th May was after I had done a manual reading as it had been a good few days since it was picked up…

Then the 16th May was probably just a too-high estimate, and should be corrected once a new reading was/is received.
