That's according to Consumer Intelligence, which estimates that 51% of car insurance customers could save up to £388.64 by shopping around.
Even if you don't switch insurer, getting quotes from others could help you save money through haggling.
Here we explain how car insurance auto-renews and how this convenience could be costing you dearly.
What is auto-renew car insurance?
When you take out a car insurance policy, the 12-month agreement will usually stipulate an auto-renewal clause. This means that once your initial one-year contract lapses, you will be automatically enrolled for another year.
Although insurers have been banned from charging customers more just because of their loyalty, premiums can still increase if your insurer's costs have gone up (for instance, repairs and parts). And not all insurers are raising prices at the same rate.
This could mean last year's bargain cover is now far from competitive.
Using a comparison tool is one of the easiest ways to see what all the different policies are, their costs, how they were scored by their customers and Which? experts, and whether their unique offering is suitable for you and your car.
Will I lose my no-claims discount?
Each provider will have different no-claims discount caps, both in terms of how much you could save and how many claims-free years it'll take you to get there.
Research published by Confused.com revealed that the average car insurance with zero years’ no-claims discount (NCD) was £1,734. This drops to £989 with two years NCD, or even lower to £522 with 10 years or more.
So, it's worth checking the biggest NCD on offer from insurers for your claims record, although make sure getting a low premium remains your first priority.

The optimal time to renew your car insurance is 21-30 days prior to your policy expiring.
If you leave it too late, or forget, your auto-renewal will kick in and you could be tied to your current insurer for another 12 months.
There are drawbacks if you decide to switch providers halfway through your insurance term – you'll usually be charged a fee for leaving early, and you may end up paying up for two insurance policies during the crossover period.
This cost can easily be avoided if you wait, then shop around 2-4 weeks before your policy ends. Your provider should send you a letter during this period to remind you of the upcoming renewal.
Can I switch off auto-renewal?
Yes. When you start a policy with an insurer, they will automatically opt you into auto-renewal. You can call them and ask to opt out to ensure that your policy will not renew at the end of your agreement.
Whether you choose to move or stay with your current provider, shopping around and finding out what the best car insurance deals are is always better than letting you policy auto-renew.
