OVO Energy Wrong Meter Reading: What to Check Before You Complain
This supplier-specific page is for users who already know the supplier and the billing problem. It is not affiliated with OVO Energy; it simply points you to the right checks and complaint wording.

OVO Energy complaint wording starter
Account number: [account number]
I am writing about [one specific issue] on my account.
The evidence I am relying on is: [bill / reading / balance / forecast / supplier message].
Please review this issue and provide: [corrected bill / breakdown / refund / direct debit review / written explanation].
If you reject the request, please explain your reasoning in writing and confirm the complaint reference.
The rules are the same for every supplier
This is worth saying before anything else, because people assume their supplier is uniquely difficult and it changes how they complain. Every licensed supplier in Great Britain operates under the same Ofgem standard licence conditions. That means, whoever you are with:
- The 12-month back-billing rule applies, under condition 21BA.
- Fixed direct debits must be set on the best and most current information available.
- A credit balance must be refunded on request unless it is fair and reasonable not to.
- There must be a published complaints procedure and a final-response route.
- After eight weeks, or on a deadlock letter, the Energy Ombudsman can take the case — free, and binding on the supplier.
What differs between suppliers is the contact route, how quickly they respond, and how much of the process is automated. None of that changes what you are entitled to ask for, and none of it changes the eight-week clock.
What is different about OVO in practice
OVO absorbed SSE's household supply business in 2020, which matters for one practical reason: a long-standing customer's account history may span two billing systems. If your reading problem sits around a migration date, or if readings from before the transfer appear inconsistent with readings after it, say so explicitly and ask for the reading history across both systems. A history that starts at the migration date is not the full history.
Otherwise the rules are the ones every supplier operates under: correct the reading, reissue the bill, and the twelve-month back-billing protection applies to anything older.
The wrong-reading playbook
Photograph the meter today
The reading and the serial number, in the original file. Read the meter itself, not the in-home display.
Compare three numbers
The reading on the bill, the reading on your meter, and the serial number on each.
Ask for the reading history
Marked actual, estimated, smart or customer. It settles almost every one of these.
| What you find | What it is | Where to go |
|---|---|---|
| Bill reading is much higher than the meter | An over-estimate, or a misread digit | Submit the actual reading and ask for a rebill |
| Bill reading is lower than the meter | Under-estimate. A catch-up bill is coming | Catch-up bills |
| Serial numbers do not match | Meter exchange not recorded, or crossed meters | Serial mismatch |
| Bill says estimated but you submitted a reading | A process failure worth naming | Ask why it was rejected and what reason was recorded |
| Run of estimates over a year old | Possible back billing | Back-billing rules |
The message to send
Copy, fill in the brackets, send through the supplier's published complaints route
Send it to the complaints address published in the supplier's complaints procedure, not to general customer service. Use the word “complaint” and ask for the reference in your first message — that is what starts the eight-week clock.
Escalating with any supplier
| Stage | What to do | Why it matters |
|---|---|---|
| 1. Find the complaints route | Every supplier must publish its complaints procedure. Search “[supplier] complaints procedure” and use the address given there, not general customer service. | General service queues do not create a complaint record. Complaint routes do. |
| 2. Use the word “complaint” | And ask for the reference number in your first message. | Without it, day 0 of the eight weeks is disputable. |
| 3. Keep it in writing | Follow any phone call with an email summarising what was agreed. | Phone notes are the supplier's record. The Ombudsman reads documents. |
| 4. Ask for a final response at week four | If nothing is moving. A deadlock letter unlocks the Ombudsman early. | Can save a month. |
| 5. Refer at week eight | To the Energy Ombudsman. Free. Binding on the supplier. | This is the point at which suppliers start moving. |

Frequently asked questions
Is BillDecoded affiliated with OVO Energy?
No. This page is independent and informational. It does not represent OVO Energy.
Should I complain to the Ombudsman first?
Usually no. Start with the supplier complaint route unless you already have a deadlock/final-position letter or the required waiting period has passed.
What if the issue is actually a meter reading problem?
Use the wrong meter reading guide and template so the supplier receives the right evidence.
OVO says my reading is implausible. What do I do?
Send the dated photograph and a one-line explanation of why usage changed, then ask what tolerance was applied and what the previous reading was. If the previous reading was an over-estimate, the earlier bill needs correcting too.
My account was moved over from SSE. Does that affect my reading history?
It can. Ask specifically for the reading history from before the migration as well as after it. A history that begins at the transfer date is not complete, and gaps around a migration are worth flagging in the complaint.
How long does OVO have to fix it?
There is no fixed deadline for a correction, but eight weeks after you raise a formal complaint you can refer the case to the Energy Ombudsman — free, and binding on the supplier. A deadlock letter opens that route sooner.
