What's Zest Car Rental like?
A good broker will not only negotiate rates with car hire companies to get you a better deal but also act as a buffer, offering extra help if things go wrong. Zest, which vows only to work with reputable providers, is the best broker in the UK.
Zest constantly monitors customer ratings of each provider it works with. If scores fall, a firm will be put under review before being removed from its site completely if there is no clear evidence of improvement.
It was awarded full marks in all but one category, including its five-star customer service. Readers told us that its agents went out of their way to help resolve any issues or problems quickly.
It's the only broker to achieve perfect results for pricing clarity. It's also the cheapest of the brokers in our table, which is remarkable because its rates always include either zero-excess insurance or excess reimbursement insurance, free cancellation up to 48 hours before pick-up and even a second driver in some locations.
As one new convert in our survey put it, ‘Zest was simply a breath of fresh air, providing everything I needed without pestering me to buy unnecessary extras. It is now my go-to car hire company.’
Should I book with Zest Car Rental?
Yes. It’s the cheapest, the best, and the only car hire broker to ever be a Which? Recommended Provider.
Because we didn't rerun the survey in 2025, we checked that Zest still met our criteria for WRP status in May 2025 and reconfirmed its status in June.
