Re: Mis-selling complaint
I am writing about an energy contract that I feel I have been mis-sold.
In my opinion, I was mis-sold the contract because:
I was told the tariff price was cheaper than our current suppliers but this isn’t the case. I agreed to the contract on 10 June and found this out a week later.
Please reply in writing within [number of days] working days.
Thank you.
Yours faithfully,
[complainant name]
About this template
What is this template?
This is a formal letter of complaint regarding deceptive sales practices in the energy sector. It contains specific fields for account numbers and reference numbers to ensure the supplier can locate the disputed contract. It is not a legal claim form or a formal ombudsman submission.
When should you use it?
Use this letter when an energy salesperson provided false information about savings to induce a contract switch. Use a Deadlock Letter instead if the supplier has already issued a final response that did not resolve the issue.
What's inside
| Clause | Name | What it does |
|---|---|---|
| Account number | Account Identification | Identifies the specific energy account and type of supply, such as Dual fuel, to which the complaint applies. |
| Mis-selling complaint | Basis of Complaint | States the consumer was told the tariff was cheaper than their current supplier but discovered this was untrue within one week. |
| number of days | Response Deadline | Demands a written reply from the supplier within a specific period, which the template defaults to 10 working days. |
Who it's for
- an energy consumer who was misled about tariff prices by a supplier
- a customer seeking a written response from British Power or another energy provider regarding a mis-sold contract
- a dual fuel or single fuel account holder disputing an agreement made on a specific date

Mostly US and UK law. Some templates use general commercial terms that work across jurisdictions, and many note which law they're written for.
It depends on the situation. Templates work well for routine business agreements. For anything involving significant money, complex IP, employment, or areas you're unsure about, it's worth getting professional advice before you sign. GitLaw provides templates and tools, not legal advice.
