Energy Ombudsman Complaint Escalation Letter Template & Generator

If you need to escalate unresolved energy complaint to the Energy Ombudsman, a written letter is the recommended first step — it creates a clear record and shows you're pursuing the matter formally. Below is what a strong Energy Ombudsman complaint escalation should include, plus a free tool to generate yours.

What this letter needs to cover

• Summarise the complaint, the supplier's response (or lack of response after 8 weeks), and why it is not resolved
• Request the Ombudsman investigates
• Note that a deadlock letter or 8-week period has elapsed
• State the desired outcome clearly

When it's time to escalate to the Ombudsman

If your energy complaint hasn't been resolved after 8 weeks, or your supplier has issued a final response you're not satisfied with, you're entitled to escalate to the Energy Ombudsman for a free, independent review. This is often a genuinely effective route, since Ombudsman decisions can be binding on the supplier if they favour you.

What this letter or complaint needs to cover

• A clear timeline of your original complaint and the supplier's response, or lack of one
• Confirmation that either 8 weeks have passed or you've received a final response letter
• What outcome you were seeking from your supplier, and why you remain dissatisfied
• Copies of relevant correspondence to support your case

What the Ombudsman can actually do

The Ombudsman can require an apology, an explanation of what went wrong, a practical action to put the problem right, or a financial award. Its decision is binding on the energy company but not on you. The Energy Ombudsman covers England, Wales and Scotland: in Northern Ireland, take an unresolved complaint to the Consumer Council (0800 121 6022).
