Complaint route

How an energy complaint should progress

Complain to the supplier first and keep a clear timeline of bills, readings, payments and responses.

Energy complaint route

Complain to the supplier first

Set out the account, bill or service issue with dates, meter evidence and requested remedy.

Ask for a deadlock position

If the complaint stalls, ask the supplier to explain its position or issue a deadlock letter.

Escalate after eight weeks

If unresolved after eight weeks or after deadlock, consider the Energy Ombudsman if the issue is in scope.

Keep meter photographs, bills and account statements because they often decide the dispute.

Outcome request

What you can ask E.ON Next to do

The strongest complaint letters state the practical result you want, not just what went wrong.

Corrected bill Refund or account credit Payment plan review Meter data review Service fix Complaint escalation

Use this page to prepare a clear, structured complaint to E.ON Next. The aim is to explain what has gone wrong, what you want corrected, and the evidence that supports your position.

What this letter should achieve

  • Set out the issue clearly with dates, account number, and bill references.
  • Explain the financial impact (overpayment, unexpected debit, missed refund).
  • Request a specific remedy (bill correction, refund, compensation, or account review).
  • Ask for a written response and confirmation of the outcome.

Common issues people complain about (Energy & utilities)

Typical themes include: Billing error, Overcharge, Direct debit issue, Meter problem, Switching issue, Refund request. Keep your letter focused on the main issue and avoid unrelated grievances.

What to include

Evidence: Account number, meter readings, bills/statements, tariff details, correspondence, and photos of meter readings where relevant.

  • Dates of bills and disputed charges.
  • Meter readings you have provided and dates submitted.
  • Any agreed payment plans or tariff changes.
  • What you have already tried (calls, online chat, complaints form) and the outcome.

Your rights as an energy customer

Energy suppliers must bill you accurately and treat you fairly under Ofgem rules. If there is a billing error, you are entitled to a correction and refund of overpayments.

  • If you have been back-billed for energy used more than 12 months ago due to supplier error, back-billing rules may apply.
  • If your direct debit has been set too high without clear justification, you can request a review.
  • If your account is in credit, you may request a refund.

Referring calmly to Ofgem rules and fair billing standards can strengthen your complaint.

Escalation and timeframes

Expected wait: Energy suppliers normally have up to 8 weeks to resolve a complaint before you can escalate, unless you receive a deadlock letter earlier.

Escalation route: If unresolved after 8 weeks or upon receipt of a deadlock letter, you can escalate to the Energy Ombudsman for independent review.

Practical tips

  • Provide clear meter readings and photographs where possible.
  • Keep copies of bills showing disputed charges.
  • Set out the exact amount you believe is incorrect.
  • Remain factual and avoid emotional language.

E.ON Next complaint FAQs

How long does E.ON Next have to resolve my complaint?
Energy suppliers generally have up to 8 weeks to resolve a complaint. If unresolved after this period, or if you receive a deadlock letter earlier, you can escalate to the Energy Ombudsman.
What if I have been overcharged?
Provide copies of the relevant bills, your meter readings, and explain clearly where you believe the error occurred. You can request a corrected bill and refund of any overpayment.
Can I get compensation for billing mistakes?
Compensation may be available in certain circumstances, particularly where there has been significant inconvenience or failure to follow regulatory standards.
What are back-billing rules?
If your supplier has failed to bill you correctly and later issues a large catch-up bill, back-billing rules may limit how far back they can charge where the delay was their fault.
When can I go to the Energy Ombudsman?
You can escalate to the Energy Ombudsman after 8 weeks have passed since your complaint was raised, or sooner if you receive a deadlock letter confirming the supplier cannot resolve the issue.
