What the alternative costsNo priced human or software alternative is provided in the available tool data.
If this goes wrong: the complaint contains an incorrect reading or charge, or asks for the wrong remedy, and you may have to correct it and continue the dispute yourself.

How to actually do it
- Open the energy bill, meter-reading records, payment records and previous messages with the supplier, and put them in one folder.
- Copy the bill text or upload readable copies to a chatbot, after redacting passwords, bank details and any personal information that is not needed for the complaint.
- Add the supplier name, supply address, account reference, disputed amount, relevant dates, meter readings and the outcome you want.
- Paste the prompt and ask the chatbot to produce the evidence table and complaint email, then answer its focused questions using your records.
- Compare every amount, date, reading, payment and quoted supplier statement in the draft with the original bill and correspondence, and remove any unsupported claim.
- Open the supplier's current complaints information on its official website and check the correct submission channel and any escalation information before sending.
- Send the final complaint through the supplier's stated channel, save the sent message and attachments, and record the date and any reference number.
Prompt
Help me draft a formal complaint to my UK energy supplier about an energy bill. Use only the facts and documents I provide, and do not invent readings, dates, prices, contract terms, payments, account details or legal rights. First list the disputed points in a table with the supporting evidence and any missing information. Then draft a concise complaint email with a clear subject line, the account holder's name as [NAME], the supply address as [SUPPLY ADDRESS], the account reference as [ACCOUNT REFERENCE], and the supplier as [SUPPLIER]. State what I believe is wrong, give the relevant dates and meter readings, explain the resolution I want, and ask for a written response. Keep the tone firm and factual. Do not include full bank details, passwords or unnecessary personal data. Mark every statement that needs checking against the bill or correspondence. Do not give legal advice or claim that a particular escalation route, deadline or compensation entitlement applies unless I provide an official source confirming it. If the evidence is incomplete, ask focused questions before finalising the draft.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
What it gets wrong
- AI cannot access your supplier account, meter data or payment history unless you provide the relevant evidence.
- AI cannot confirm that a charge reflects your current tariff, meter configuration or supplier records.
- AI cannot take responsibility for the accuracy of the complaint or for sending it through the correct channel.
- AI cannot decide whether the dispute needs legal action or representation by a solicitor.
- AI cannot guarantee that a supplier will accept your requested remedy.
Even on a YES, the friction has a name: legal accountability, verification cost and real time truth.

FAQ
- Can AI write a complaint about my energy bill?
- Yes. Give it the bill, relevant readings and previous correspondence, and it can organise the disputed points and draft a firm, factual complaint. Check every figure and date against the originals before sending.
- What should I include in an energy bill complaint?
- Include the supplier, supply address, account reference, disputed amount, relevant dates, meter readings, payments, supporting correspondence and the outcome you want. Do not include passwords or full bank details.
- Can AI tell me if my energy bill is wrong?
- AI can compare the figures you provide and highlight inconsistencies, but it cannot confirm the supplier's tariff, meter data or account records without reliable evidence. Check the result against the bill and the supplier's explanation.
- Can AI deal with an energy supplier dispute for me?
- No. It can prepare the complaint, but you must check it, send it and continue the dispute. This is not professional advice, and a serious case may need a solicitor.
