What to Do When Your Energy Complaint Is Stuck
Most business energy issues start small: a wrong meter reading, an unexpected adjustment, or a missed refund. But when suppliers delay, deny, or ignore valid complaints, the problem grows. At some point, you must decide whether to escalate the issue formally. Doing so the right way, at the right time, can make the difference between months of frustration and a fast resolution.
This guide explains when and how to escalate an unresolved billing complaint with your energy supplier. You’ll learn what counts as “reasonable resolution time,” how to structure escalation, and how Energy Problems supports you throughout the process.
Knowing When to Ask for Help
If your supplier’s behaviour feels unreasonable or if you’re spending more time chasing them than running your business, that’s your signal to get expert help. A professional intermediary like Energy Problems brings structure, authority, and experience to complex disputes.

Recognising When a Complaint Is Stuck
Energy suppliers have internal complaint-handling procedures, but many fail to follow them properly. A complaint is considered “stuck” when:
- Your supplier stops responding or repeats the same response without progress.
- They acknowledge your issue but provide no timeline for resolution.
- They send revised bills that still contain the same errors.
- You’ve been waiting more than 8 weeks without closure or written outcome.
At this stage, continuing to send emails or call customer service rarely helps. A structured escalation – internal first, then external if required – puts pressure on the supplier to act.
The 8-Week Rule
Under Ofgem rules, business energy suppliers have up to 8 weeks to resolve a formal complaint. If they haven’t provided a satisfactory resolution by then, or if they issue a “deadlock letter” stating no further action will be taken, you have the right to escalate the matter to the Energy Ombudsman.
This 8-week timeline protects you from indefinite delays. You don’t need to wait beyond it and suppliers cannot penalise you for taking your case to an independent authority.
Steps Before Escalation
Before you formally escalate, make sure you’ve taken these preparatory steps:
- Keep a written record of every email, call, and bill received.
- Request written updates from your supplier after each response.
- Ask for a named contact in the supplier’s complaints department.
- Confirm your complaint reference number – this will be needed for the Ombudsman.
If you’ve already done all of this and progress has stopped, escalation is the logical next step.
Internal Escalation Within the Supplier
Before approaching external authorities, you can often speed things up by asking for your complaint to be reviewed by a senior manager or “escalation team.” This signals that you expect formal handling rather than another routine reply.
Example message:
“We’ve been waiting [X weeks] for resolution of our billing dispute under complaint reference [number]. Please escalate this matter internally and confirm the name of the person now responsible for review.”
This approach often moves your case to a more experienced handler. If it doesn’t, you’ll have proof that the supplier failed to act – which strengthens your position if you proceed to the Ombudsman.
Escalating to the Energy Ombudsman
The Energy Ombudsman is an independent body approved by Ofgem. It reviews energy complaints fairly and has the power to require suppliers to correct billing errors, apologise, and even offer compensation.
You can go to the Ombudsman if:
- Your complaint has been unresolved for more than 8 weeks, or
- You’ve received a “deadlock letter” from your supplier.
When submitting your case, include:
- Copies of your invoices and disputed bills
- Emails or letters showing your attempts to resolve the issue
- Photos or logs of meter readings if relevant
- Any written supplier responses (or lack thereof)
The Ombudsman typically responds within a few weeks. If they rule in your favour, the supplier must comply with the decision.
Common Mistakes Businesses Make During Escalation
- Submitting incomplete evidence – missing invoices or emails can delay review.
- Using emotional or accusatory language – facts carry more weight than frustration.
- Accepting vague promises from suppliers – always ask for written confirmation.
- Failing to record dates – timelines matter when showing supplier delay.
Escalation is about clarity, not confrontation. Keeping everything documented and professional increases your chances of success significantly.
8. What to Expect After Escalation
Once the Ombudsman receives your case, they’ll notify the supplier, who must respond within a set timeframe. You’ll then receive a summary of both sides’ positions. The Ombudsman’s decision is binding on the supplier, but not on you – meaning you can reject it if unsatisfied and pursue other options.
Outcomes typically include:
- Correction of inaccurate bills
- Refunds or credits for overcharges
- Formal apology or supplier process change
- Compensation for time or inconvenience
In most cases, disputes are resolved at this stage without further escalation.
Preventing Future Complaints
Once your case is closed, take steps to reduce the risk of new disputes. Many long-running billing issues are preventable with a few simple processes.
- Check your bills monthly for estimated readings.
- Submit meter data regularly – or use an automated meter reader (AMR).
- Keep written confirmation of tariff rates and renewal dates.
- Audit your bills quarterly to confirm consistency.
- Work with an independent intermediary to oversee supplier performance.
These steps turn energy management from reactive firefighting into proactive control.
