As of 13 August 2026, AI can only partly switch energy supplier.
Most people should hand this to a purpose-built tool.

If this goes wrong, you can select an unsuitable tariff, miss a contract term or incur a charge while believing the comparison was complete.

Second choiceA chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.
How to actually do it
- Open your latest energy bill and copy the supplier name, tariff name, unit rates, standing charges, meter type, payment method, contract end date and any exit charge into the prompt.
- Gather your annual usage, or a recent period of electricity and gas usage, and paste both figures into the prompt with the units shown on the bill.
- Tell the chatbot your postcode or region and your priorities, then ask it to produce a comparison table using only supplied or clearly linked current information.
- Open each supplier's own tariff page or the relevant GOV.UK energy guidance and compare the chatbot's rates, standing charges, contract terms, eligibility and payment conditions with those sources.
- Recalculate the comparison using your actual usage and remove any tariff with an unverified rate, unavailable region, unsuitable meter requirement or unacceptable exit term.
- Open the chosen supplier's official switching page, enter the details yourself, check the final tariff and contract information against your bill and the comparison, then submit the switch only when they match.
Prompt
Help me compare energy suppliers and prepare to switch in the UK. Do not switch me, submit any form or invent a tariff, rate, saving, contract term or eligibility rule. First list the information you need from me: postcode or region, current supplier, current tariff name, whether it is fixed or variable, unit rates, standing charges, payment method, meter type, whether I have a smart meter, annual or recent usage, contract end date and any exit charge shown on my bill. Then use only the figures and links I provide, or clearly identified current official supplier information, to create a table showing supplier, tariff, unit rates, standing charges, estimated cost using my stated usage, contract length, exit terms, payment method, eligibility and source link. Mark anything missing or uncertain. Do not recommend a tariff until you have separated verified facts from assumptions. Finish with a checklist of what I must confirm on the supplier's own website before accepting the switch. My details are: [paste bill or tariff information here]. My usage is: [paste annual or recent electricity and gas usage here]. My priorities are: [for example, lowest cost, fixed price, renewable supply or no exit charge].
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
Hand it to a person
The distant thirdA person who owns the outcome does this end to end, worth it when the failure is dear.
What it gets wrong
- It cannot know which tariffs are genuinely available to your address unless you provide current, relevant source information.
- It cannot guarantee that rates, standing charges, eligibility rules or contract terms have not changed.
- It cannot judge whether a fixed or variable tariff suits your tolerance for changing bills and contract restrictions.
- It cannot accept the supplier contract or take responsibility for an inaccurate meter reading, account detail or switching choice.
- It cannot replace the supplier's final quote and confirmation on its own website.

FAQ
- Can AI find me the cheapest energy supplier?
- It can organise a comparison if you provide accurate usage and current tariff information, but it cannot guarantee the cheapest available option. Check every rate, standing charge, eligibility condition and contract term on the supplier's own website before switching.
- Can ChatGPT switch my energy supplier for me?
- No. A chatbot can prepare the information and checklist, but you must complete and accept the switch through the supplier's official process. Check the final tariff and account details yourself before submitting anything.
- What information do I need to switch energy supplier?
- Gather your latest bill, current supplier and tariff, meter type, payment method, electricity and gas usage, contract end date and any exit charge. You may also need your address details and the account information requested by the new supplier.
- Is it safe to use AI to compare energy tariffs?
- It is useful for extracting figures and structuring a comparison, but this is not professional advice. For a serious case involving debt, vulnerability, a disputed bill or uncertainty about your contract, speak to a qualified energy adviser or Citizens Advice, and verify the final offer with the supplier.
