It might be a good idea to look for excess insurance for peace of mind before you pick up your car. Getting it a few weeks or even months before your trip could save you a lot of money.
Buying your excess insurance in advance also means you don’t need to use a credit card to leave a large deposit with the rental company. Sometimes, the deposit can be between £500 and £1,200.
While it’s only a deposit, if you need to claim on the insurance the money is taken from your card. You then need to claim back what isn’t used to fix any damage from the insurer. It means you could be left with a large credit card bill to pay, without yet having the money back to pay for it.
The credit card will usually need to belong to whoever made the booking too, so always double-check the T&Cs if this might be a problem.
If you don’t have a credit card, some firms could force you to take their insurance because they don’t accept deposits on debit or prepaid cards.
If you rent cars several times a year, an annual excess insurance policy might be even cheaper.
