Standalone Car Hire Excess Insurance: Is It a Better Deal?
Updated Sep 11, 2026 · Daniel Moreau · 5 min read
Buying excess cover separately is often far cheaper than the rental desk’s option. There are trade-offs to understand.
What this article covers
Rental cars usually come with basic damage cover, but with a high excess (deductible) that you pay if the car is damaged. Rental desks then offer to reduce that excess to zero for a daily fee.
Standalone excess insurance, bought separately in advance, does a similar job — often for much less.
How standalone cover works
If the rental car is damaged, the rental company charges you the excess, typically from your credit card. You then claim that amount back from your standalone insurer. You pay upfront and wait for the refund.
Advantages
- Usually much cheaper than buying the rental company’s cover daily
- Annual policies cover multiple trips
- Often covers parts excluded by the desk’s cover, such as tyres, glass, and the underside
Disadvantages
- The rental company still takes a large deposit hold on your card
- You have to pay the damage charge first and claim it back
- Some rental desks push hard for their own product
- Claims require paperwork: rental agreement, damage report, and proof of payment
What to check before buying
Make sure the policy covers the countries you are visiting, the type of vehicle, and the length of rental. Check the maximum claim limit against the excess on your rental. Read the exclusions — off-road driving, unauthorised drivers, and driving under the influence are standard exclusions.
