Step two

How to complain about EDF Energy

Work through the stages in order. Each one creates the paper trail the next stage needs.

  1. 1

    Stage 1

    Contact EDF customer service

    Same day

    Call 0333 200 5100 or email complaintresolution@edfenergy.com. Explain the billing, meter or supply problem and ask for a complaint reference.

    Record the date, adviser name and reference.

    For a gas leak or loss of supply, call the network operator first. The national gas emergency number is 0800 111 999.

  2. 2

    Stage 2

    Raise a formal complaint with EDF

    Within 8 weeks of the issue

    Put the complaint in writing through the complaints page or by email. Include your account number, meter readings, key dates and the remedy you want.

    Ask for written acknowledgement.

    Keep copies of bills, meter photos and chat transcripts.

  3. 3

    Stage 3

    Wait for the final response

    Up to 8 weeks

    EDF has up to eight weeks to resolve a formal complaint. If it offers a resolution, get the credit or action confirmed in writing.

    Check that any credit appears on your next bill.

    You can ask for a deadlock letter before the eight weeks are up if talks stall.

  4. 4

    Stage 4

    Escalate to the Energy Ombudsman

    After 8 weeks or a deadlock letter

    The Energy Ombudsman is free and independent. It can review the complaint after eight weeks or as soon as you have a deadlock letter.

    Submit your complaint reference, timeline and evidence.

    The supplier must comply with an ombudsman decision you accept.

  5. 5

    Stage 5

    Know what Ofgem can and cannot do

    Anytime

    Ofgem does not resolve individual billing disputes. It monitors supplier behaviour and can act where it sees a pattern of rule-breaking.

    Report systemic issues through Ofgem or Citizens Advice.

    For a money claim the ombudsman cannot award, court is the remaining route.

Questions

EDF Energy FAQ

How do I contact EDF customer service?

Call 0333 200 5100 (Mon–Thu 9am–5pm; Fri 9am–4pm) or email complaintresolution@edfenergy.com. The complaints resolution team is on 0333 200 5101.

How do I make a formal complaint to EDF?

Use the EDF complaints page or email complaintresolution@edfenergy.com. Include your account number, meter readings, key dates and the remedy you want. Ask for a complaint reference and written acknowledgement.

How long does EDF have to resolve a complaint?

Up to eight weeks from the formal complaint. If it is resolved sooner, get the remedy confirmed in writing. If not, ask for a deadlock letter so the Energy Ombudsman can take the case.

Can the Energy Ombudsman make EDF pay compensation?

The Energy Ombudsman can direct a supplier to apologise, credit an account or pay compensation. The supplier must comply with a decision you accept. Ofgem does not award compensation in individual disputes.

Can I switch energy supplier while I have a complaint?

Usually yes. A complaint does not normally block a switch, and the new supplier handles the transfer. Keep the complaint open with the old supplier, especially if money is owed or a final bill is disputed.

What can the Energy Ombudsman award?

It can require an apology, a clear explanation, corrective action and a financial award where the supplier got things wrong. Awards are decided case by case, so keep receipts and evidence of any loss.

Does the price cap limit my total bill?

No. The price cap limits the unit rate and standing charge on a default tariff, not the total you pay. Your usage still drives the final amount. Compare the rates on your bill with the published cap for your region and payment method.
