As of 13 August 2026, AI can only partly check whether your energy bill is wrong.
This still needs a person who signs their name to it.

What the alternative costsThe listed commercial tools have no energy-billing alternative or price for this task.
If this goes wrong, you may challenge a valid bill, miss a genuine error or pay the wrong amount while the supplier investigates.

How to actually do it
- Open the bill and redact your account number, address, meter point reference and other personal details.
- Gather the tariff confirmation, meter readings with their dates, payment records and any supplier messages covering the same billing period.
- Paste the bill and those supporting figures into a chatbot using the prompt above, keeping labels and units exactly as shown.
- Ask the chatbot to show its recalculation of every charge and to separate proven arithmetic errors from points needing supplier records.
- Compare each calculation against the original bill and check the extracted readings, dates, rates, payments and credits against your documents.
- Contact your supplier with the specific discrepancy and copies of the relevant evidence, and ask for a corrected bill or a written explanation.
- If the supplier does not resolve a serious dispute, take the written response and your evidence to a qualified energy adviser or solicitor.
Prompt
Check whether this UK energy bill appears to contain an error. I will paste the bill and any tariff or meter-reading information below. Redact account numbers, addresses and other personal details first. Extract the billing period, opening and closing meter readings, units used, unit rates, standing charges, discounts, payments, VAT and total. Recalculate each subtotal and the final balance using only the figures provided. Compare the bill with the tariff details and readings I provide. Separate arithmetic errors, missing payments, unusual consumption and issues that cannot be checked without the supplier's records. Do not invent a rate, reading, rule or explanation, and do not claim that the bill is definitely wrong unless the supplied figures prove it. Show every calculation, list the exact questions I should ask my supplier, and state what evidence I should attach to a complaint. This is not professional advice. Bill: [paste bill here]. Tariff details: [paste tariff details here]. Meter readings and dates: [paste them here]. Payments or credits: [paste them here].

What it gets wrong
- AI cannot see your supplier's meter records, account history or internal billing adjustments.
- AI cannot confirm whether a meter reading was genuinely taken on the stated date or whether the meter is faulty.
- AI cannot reliably know which tariff terms or supplier correction rules apply unless you provide the relevant documents.
- AI cannot make the supplier correct the account or accept responsibility for a billing error.
- A plausible recalculation can still be based on a misread bill, so the source figures need checking against your documents.

FAQ
- Can ChatGPT check if my energy bill is correct?
- Partly. It can extract the figures, check the arithmetic and compare the bill with tariff and meter-reading information you provide. It cannot confirm the supplier's records or make the supplier correct the account.
- How do I know if my energy bill is wrong?
- Compare the billing dates, opening and closing readings, units used, unit rates, standing charges, payments, credits and VAT with your own records. A chatbot can help calculate the totals, but ask your supplier to confirm any disputed reading, tariff application or account adjustment.
- Can AI read my energy bill for me?
- Yes, if you provide a clear copy with personal account details removed. It can summarise the charges and identify figures that do not add up, but it cannot verify information held only in the supplier's system.
- What should I do if my energy supplier has overcharged me?
- Write to the supplier with the exact discrepancy, your supporting readings or payment evidence and the correction you want. This is not professional advice; for a serious dispute, speak to a qualified energy adviser or solicitor.
