EDF Energy Back Billing: 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 EDF Energy; it simply points you to the right checks and complaint wording.

EDF 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 EDF in practice
Nothing about EDF changes the back-billing rule — and that is the point worth internalising before you write. Ofgem's condition 21BA binds every licensed supplier in Great Britain identically. A supplier cannot have a “policy” that overrides it, and a complaint handler telling you the charge stands because of an internal policy has not answered the question.
What is worth doing on a large EDF account is asking for the breakdown by supply period before arguing about the total. Older accounts frequently carry a mix: recent catch-up charges that are properly payable alongside older charges that may not be. Splitting those two in your first message is what gets the older half looked at seriously.
The back-billing playbook
Take the date printed on the bill and subtract twelve months. Everything hinges on which side of that line each charge sits.
Charges before that date
Potentially protected under Ofgem's condition 21BA, if the supplier failed to bill accurately at the time. Ask for the balance broken down by supply period and for the reading-request history.
Charges after that date
A catch-up bill, and normally payable. Your questions are about the accuracy of the reading, how consumption was apportioned across rate periods, and the repayment period.
| Ask for | What it proves |
|---|---|
| The balance broken down by supply period | Which charges fall outside twelve months |
| The full reading history, marked by type | Whether the supplier had what it needed to bill |
| Every bill or statement issued, with dates | Whether accurate billing actually happened |
| Every reading request or access attempt, with dates | Whether the obstruction exception could apply |
| Which exception is relied on, if any | Forces them to commit to a position in writing |
The full rule, the exceptions and a worked example are on back-billing rules. Bring the answers to those five questions back to it.
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 EDF Energy?
No. This page is independent and informational. It does not represent EDF 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.
Does the 12-month back-billing rule apply to EDF?
Yes. Ofgem's Standard Licence Condition 21BA binds every licensed domestic supplier in Great Britain identically and has done since 1 May 2018. No supplier can have an internal policy that overrides it.
EDF says the charge is valid. What do I ask next?
Ask which exception to the back-billing rules they are relying on, and for the evidence supporting it — typically the record of reading requests or attempted meter access. A supplier that cannot produce that record has effectively conceded the point.
Should I pay the bill while I dispute it?
Pay the part relating to the last twelve months and say in writing that you are doing so. Ask for collection activity on the disputed older portion to be paused. Refusing to pay anything moves the argument onto your payment behaviour.
