How we score

We read the terms, help pages and prices that companies publish. Every data point links to its source and shows when we checked it. We do not book cars, collect reviews or publish customer opinions. We compare only what is written.

If something is not published, we mark it as not stated. If two pages disagree, we report the more cautious condition.

Formula

The score runs from 1 to 10: 1 + 9 × the weighted sum of the criteria below, each scored from 0 to 1, capped at 9.5 because published terms alone cannot prove a perfect service. Unknown values get a low neutral score, never a guess.

• Deposit (40%). Zero scores 1. The higher it is, the lower the score, reaching 0 at £1 000.
• Cards accepted (30%). Debit cards count most, then prepaid. A required credit card lowers the score.
• Excess (20%). Zero scores 1. The higher it is, the lower the score, reaching 0 at £2 000.
• Minimum age (10%). Lower is better. 18 scores 1 and 25 scores little.

How this site makes money

Some links may become partner links that pay us a commission. A partner link is labelled next to the button. Commission never changes the score, which comes only from the formula above.
