As of 13 August 2026, AI can only partly compare car hire prices in the UK.

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

   Second choice

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. Open the booking sites or supplier pages for the UK journey and enter the same pick-up location, drop-off location, dates, times, driver details and vehicle requirements on each site.
   2. Save each current quote link or screenshot and copy the displayed price, vehicle class, mileage, fuel policy, deposit, excess, insurance, additional-driver charge, cancellation terms and mandatory fees.
   3. Check the booking pages for hidden or separate terms, including airport or railway-station charges, one-way fees, young-driver rules, payment timing and VAT information, then add those details to the source notes.
   4. Paste the trip details and all quote links or text into the prompt, keeping each quote clearly labelled with its supplier.
   5. Ask the chatbot to produce the comparison table and to mark every absent term as not stated rather than filling gaps.
   6. Open the original supplier page for the proposed cheapest quote and compare its final total, vehicle class, excess, deposit, fuel policy and cancellation terms against the chatbot's table.
   7. Send the checked comparison and source links to the colleague or travel approver who authorises the work booking, then book only from the confirmed supplier page.

   Prompt

   Compare the UK car hire quotes and supplier pages pasted below for this work trip.
   
   Trip details:
   - Pick-up location: [location]
   - Drop-off location: [location]
   - Pick-up date and time: [date and time]
   - Drop-off date and time: [date and time]
   - Driver age and number of drivers: [details]
   - Vehicle needs: [details]
   - Mileage requirement: [details]
   - Business requirements: [for example, named driver, VAT receipt, cancellation flexibility]
   
   For each quote, extract only information stated in the supplied material. Compare the total payable price, currency, vehicle class, supplier, collection and return arrangements, mileage, fuel policy, deposit, excess, insurance included, additional driver charges, cancellation terms, payment terms and any mandatory fees. Do not assume that similarly named vehicles or insurance products are equivalent. Separate the advertised price from unavoidable charges and mark any missing or unclear information as "not stated". Do not invent current prices, availability, supplier policies or savings.
   
   Create:
   1. A like-for-like comparison table.
   2. A list of charges or terms that are not comparable.
   3. The cheapest quote only where the evidence supports that conclusion.
   4. Three specific checks I must make on the original supplier page before booking.
   5. A short recommendation for a work booking, with uncertainty clearly stated.
