PARTLY

As of 13 August 2026, AI can only partly compare energy suppliers for your new home.

This still needs a person who signs their name to it.

What the alternative costsThe listed commercial tools provide no sourced price for an energy-supplier comparison.

If this goes wrong, you may choose a tariff that costs more than expected or has terms that do not suit your new home.

What to actually do

  1. Hand it to a person

    The route this page recommends

    A person who owns the outcome does this end to end, worth it when the failure is dear.

  2. Use a tool built for this

  3. Do it yourself

    The distant third

    A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

    How to actually do it

    1. Gather your new home's postcode area, move-in date, meter type, heating fuel and any available annual electricity and gas usage from the landlord, seller or current bills.
    2. Open the official pages for the suppliers or tariffs you are considering and copy the unit rates, standing charges, contract terms, payment method, exit fees and eligibility conditions.
    3. Paste the home details and the copied tariff information into the prompt, keeping each supplier's information clearly labelled.
    4. Ask the chatbot to produce the comparison table and calculations, and require it to mark missing information instead of filling gaps.
    5. Compare every rate, standing charge, contract term and fee in the answer against the current supplier pages you opened, correcting any mismatch.
    6. Contact the chosen supplier to confirm the tariff is available for your new address and ask how the opening meter reading and switch will be handled.
    7. Save the confirmed tariff details and submit the switch only after checking the contract length, payment method, estimated usage and exit terms.

    Prompt

    Compare the energy supplier options below for my new home in the UK. Use only the tariff information I provide or current information from the official supplier pages that I paste in. Do not invent rates, estimates, discounts, savings, availability or contract terms.
    
    Home details:
    - Postcode area: [postcode]
    - Move-in date: [date]
    - Property type and size: [details]
    - Number of occupants: [number]
    - Heating and hot water: [gas, electricity or other]
    - Meter type: [standard, smart, prepayment or unknown]
    - Expected annual electricity use: [kWh or unknown]
    - Expected annual gas use: [kWh or unknown]
    - Current supplier or existing tariff, if any: [details]
    
    Supplier information:
    [paste each supplier's official tariff details, including unit rates, standing charges, payment method, fixed or variable terms, exit fees, discounts, renewable claims and any eligibility conditions]
    
    Create a table for each option with supplier, tariff name, fuel covered, unit rates, standing charges, contract type, length, exit fees, payment method, assumptions and any missing information. Separate confirmed figures from estimates. If usage is missing, do not calculate an annual cost; explain what I need to obtain first. If usage is available, show the calculation for each fuel and state that the result is an estimate. Identify which option appears cheapest, which is most flexible and which has the fewest unknowns, without claiming that any option is best for me. Finish with a short checklist of the figures and terms I must confirm on the supplier's current page before switching.

    Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

FAQ

Can AI find the cheapest energy supplier for my new home?
Partly. AI can compare current tariffs and calculate estimates when you provide reliable rates and usage, but it cannot guarantee that the information is current or that the cheapest option is available at your address. Check the final tariff on the supplier's official page.
What information does AI need to compare energy suppliers?
Give it your postcode area, move-in date, meter type, heating fuel and expected annual electricity and gas use. It also needs each tariff's unit rates, standing charges, contract terms, payment method, exit fees and eligibility conditions.
Is it safe to use AI to choose an energy supplier?
It is useful for organising and explaining tariff information, but you should not rely on an unverified comparison. Check every figure and term against the supplier's current offer, then confirm availability and the opening meter process with the supplier.
Can AI compare energy tariffs without my energy usage?
It can compare the structure of the tariffs, such as unit rates, standing charges, contract length and exit fees. It cannot calculate a meaningful annual cost without a usage figure, so ask it to list the missing information rather than estimate it.
