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:

If you look at the daily readings, it should show whether it’s manual (usually when you’ve input a reading, smart (directly from a smart meter) or estimated (when the system has estimated).

Hey ​@brb2024 

 

Welcome to the Forum, I’m glad to see BPLightlog has already stopped by with some really helpful advice here. 

 

It sounds likely to be something to do with estimated/smart readings. Were you able to find your readings on your account? Did that help clear things up further?

 

Let us know how you get on.

Hello,

Thanks for the tips. I couldn't see in the app where you can tell if it is an estimate or not. Unfortunately, I also didn't download any data for Dec so I can't show you what I mean. It seemed to show pretty accurate data for each day but these changed at the end of the month (we have a smart meter). I think they must have been estimates based on my usage the previous month. I was expecting a higher bill in December but not as much as it turned out to be! I'll be aware of that this month.

Thanks again for your reply.

You’ll find that under Account > Meter Readings. If you have Beyond, the Account button is in the top right on the home page of the app.

Thanks very much, I just found it! Yeah it does look like they were estimates as it is saying there was a reading on 1 Dec and the next one was on 1 Jan. Thanks for helping to clear that up, I really appreciate it.

No worries. To help prevent this, you might want to crank up the reading schedule to Daily or Half-Hourly so that you basically never see estimates. You can do that in the app.

Hey ​@brb2024 

 

Glad to hear you managed to find that section thanks to Blastoise! Changing that should help us, and you, get a better understanding of your day-to-day usage.

 

 

Feel free to pop back any time if you’ve ever got any other questions.😊

I don’t think I would moan about an increase just before the tariff went up - you are the winner!

Just a reminder that you should always take a reading at the end of the month - or very soon afterwards.  This will correct the tariff change reading.

I really like the option to enter the readings up to 10 days after you took them.  So often it’s not convenient - or I forget - on the month end.
