I have just submitted my first readings, but I'm not sure if reading 1 on my meter is day or night?

Are you struggling to tell which reading is which on your economy 7 meter?

 

When using a traditional meter, you may see readings labeled as "high" and "low" or "day" and "night." If the labels are not there, you can check the current reading against your past readings on the ‘Meter Readings’ page of your online account or the OVO app, available for download on Android or iOS.

 

If you still can't figure it out, try a Load Test. To do this, take two sets of readings during your peak hours. Only one reading should change; this will be your daytime register.

 

 

How to perform a load test

 

Check your electricity meter twice in one day. First, read it in the morning after 9am. Then, read it again in the afternoon or evening before 9pm. After you have the two readings, email us at hello@ovoenergy.com with the information below.

  • Meter Serial Number: ***********
  • Date you took the meter readings: **/**/**
  • Morning meter readings and the time you took them: 
  • Time: **am
  • The day register ID and reading: R* - *****
  • The night register ID and reading: R* - *****
  • Afternoon or evening meter readings and the time you took them: 
  • Time: **am.
  • The day register ID and reading: R* - *****
  • The night register ID and reading: R* - *****
  • Do you have an electric heating system (e.g. storage heaters)? Yes/No

Register IDs are the little numbers or letters on the left-hand side of the reading (e.g. R1/R2/L/N etc).

It’s really important that these are submitted round the right way otherwise the amount that we bill you will be incorrect.

If you’d like the team to check this for you, please send them a private message on Facebook or Twitter with your name, DoB and account number and they can help further.

Not sure this _is_ solved by comparing numbers submitted on older bill, if I'm the only one who has ever submitted the numbers! How could I have known the correct order in the first place if there's no indication of day/night on the meter? It may have been wrong for years [gaaah!]

How reliable is the 'lower number=night rate' heuristic, because that does not fit my case?

(I have a Type 5235D-N meter and can supply photos to a suitably private party)

Why does OVO only ask for 1 meter reading line, when I have a Day Rate, Night Rate and a 3rd reading (which doesn’t have 1 or 2 next to it).

Which one am I submitting for my opening bill?

Hi @nhill 

First thing I'd check is what tariff OVO thinks you are on. If this is a single rate tariff then it may be why they are only asking for one reading.

Is your 3rd reading the total of readings 1 and 2? If so, this may be the one they are after, but only if it's a single rate tariff.

    Some great advice from @nealmurphy there!

     

    Have you applied to join us through a switch, @nhill? If so we’d recommend checking the advice given in the guide below.

     

     

    You can double-check whether you’ve signed up for a single-rate or dual-rate plan by double-checking your Welcome Pack. A dual rate plan would include ‘Economy 7’ as part of the name.

     

    If you’re not sure you’ve signed up for the right plan or need some help confirming which readings to submit we’d recommend reaching out to our Support Team. The quickest way to get in touch is via our webchat which you can find here.

     

    Hope this helps.

    Our property used to have economy 7 heating but we removed it and put in gas central heating instead.  Our electric meter seems to give us three seperate readings which I assume goes back to when it was all econmy seven.  I don’t know which is the right reading.  This wouldn’t be a problem except we now let out the flat upstairs and have to work out their electric usage so we can charge them separately.

    Hi @hungdrawnquoted if you can find out the model someone will probably be able to decode it for you. There are some guides also like this

    Every time I'm asked to submit a reading I panic because I don't know which reading to use for day or for night.  Our meter has 3 readings.  One has a small digit 1 and another has 2.  The final just has a reading.  Which is day reading and which is night?

    If you could take a photo and post it here, we’d be able to tell you 🙂

    My guess is that 1 is Rate 1, normally day/peak, 2 is rate 2, night/offpeak and the other one is the total of those two. Is that possible?

    Some meters have the day/night registers the other way round (1 - night/offpeak, 2 - day/peak). If you can find your meter reading history online (Meter readings history - OVO Energy), you can compare the historical figures with the ones on the meter to identify which is which.
