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 E.ON Next in practice
E.ON Next carries a large book of accounts brought across from earlier E.ON and npower brands, and migrated accounts are where most of the avoidable direct debit problems on any supplier sit. The pattern to watch for: a forecast built from a usage history that transferred incompletely, or a debt-recovery amount still baked into the monthly payment from a balance that was settled before the migration.
So ask two extra questions alongside the usual five. First, whether the annual forecast was built from actual readings or from a system-generated profile. Second, whether any part of the monthly amount is recovering a balance that predates the account migration — and if so, for a statement showing it is still outstanding.
The direct debit playbook
A direct debit is built from five numbers. Ask for all five and the conversation stops being about whether the payment “feels” too high.
monthly = ( forecast annual cost − credit + debt + buffer ) ÷ months
| Ask | What a good answer looks like |
|---|---|
| The forecast annual consumption, in kWh | Close to your actual last twelve months, and based on actual rather than estimated readings |
| Your balance on the review date | Matches your account screen |
| How much is debt recovery | A stated amount over a stated period |
| The target buffer and why that amount | Tied to your winter forecast, not a round number |
| The number of months being smoothed over | Twelve, unless there is a stated recovery period |
Illustration: at July–September 2026 GB average rates, 2,700 kWh electricity plus 11,500 kWh gas over a year cost £1,862.66, or £155.22 a month with zero balance. This uses older consumption assumptions, not Ofgem’s revised £1,663 headline or your supplier’s current tariff. Enter your own figures and ask the supplier to explain any gap in its forecast.
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 E.ON Next?
No. This page is independent and informational. It does not represent E.ON Next.
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.
Why did my E.ON Next direct debit jump so much?
The usual causes are a forecast built from estimated rather than actual readings, an arrears recovery amount included without being identified, or a recovery period shorter than twelve months. Ask which, specifically — a six-month recovery period can double a payment with nothing on the account screen to explain it.
My account was migrated from another brand. Does that matter?
It can. Ask whether the forecast was built from actual readings or a system profile, and whether any part of the monthly amount is recovering a balance that predates the migration. If it is, ask for a statement showing that balance is still outstanding.
Should I cancel the direct debit if it is too high?
No. Cancelling usually loses the direct debit rate and turns a billing conversation into an arrears one. Ask for the calculation, propose your own figure, and escalate through the complaints process if they will not engage.
