How to Keep Car Insurance Costs Down

Why car insurance prices vary so much

Every insurer uses its own pricing model, weighing many factors to decide how risky you are to cover. Two providers can look at the same driver, car and postcode and arrive at very different premiums. One might target younger drivers, another low-mileage commuters, another electric cars.

That is why the most effective thing you can do is compare widely. A quote that looks expensive on one platform might be cheaper elsewhere, simply because a different insurer is pricing the risk.

Your own circumstances matter too: where you live, where you park overnight, how many miles you drive, your claims history, the car and how you describe your job all feed into the price. Some of these you cannot change, but several you can describe more accurately.

Does checking quotes affect your credit score?

Getting a car insurance quote usually involves a soft credit search. It lets the insurer check your identity and assess risk, but it is not visible to lenders and does not affect your credit score.

If you choose to pay monthly, the insurer or a finance provider usually sets up a credit agreement for the instalments and may run a hard credit search. Hard searches are visible to other lenders, and several in a short time can affect your score. If you are planning a mortgage or other borrowing soon, keep this in mind; paying annually avoids the credit agreement.

Why comparison sites show different prices

Comparison sites are not copies of one another. Each works with a different mix of insurers, and some insurers only sell directly through their own websites or by phone. Running the same details through two or three sites, then checking a couple of direct-only insurers, gives you a much fuller picture.

When is the best time to get quotes?

Timing makes a real difference. MoneySavingExpert's analyses of car insurance quotes have repeatedly found that prices are lowest roughly three to four weeks before the policy starts, and rise sharply in the final two weeks.

Set a reminder about four weeks before your renewal date so you have time to compare properly. Most insurers let you buy at today's price with a future start date. Do not go too early: quoting much more than four weeks ahead can mean fewer insurers will quote.

Will staying with your insurer cost more?

Not compared with what your insurer charges new customers. Since 1 January 2022, FCA rules mean an insurer cannot offer you a renewal price higher than it would charge an equivalent new customer through the same channel. But a different insurer may still be cheaper, so check before you auto-renew.

Practical ways to reduce your premium

Quote your mileage accurately

Insurers use your estimated annual mileage to price the risk. Overstating it can push your premium up; understating it could cause problems with a claim. Give an honest, realistic estimate; the Annual Mileage Calculator can work it out from your commute and typical journeys.

Describe your job title carefully

How you describe your occupation can affect the price. You must always be truthful, but if your job has more than one accurate description, it is reasonable to check whether it makes a difference. Never use a job title that does not genuinely apply to you.

Consider your voluntary excess

Increasing your voluntary excess, the amount you agree to pay towards a claim, usually reduces your premium. Only choose a level you could afford to pay if you had to claim.

Pay annually if you can

Paying monthly is convenient but usually costs more, because it is normally a credit agreement with interest. Compare the full yearly cost of paying monthly with the annual price, and check the APR. If you can afford the lump sum, it is usually the cheaper route.

Think about the car you drive

Most cars are placed in an insurance group from 1 (cheapest to insure) to 50, set by an industry panel based on factors such as the car's price, repair costs, performance and security. Higher-powered, more expensive or harder-to-repair cars sit in higher groups. Check the group before you buy, and include insurance in the total cost of the car.

Keep your details consistent

Small inconsistencies between quotes, such as different mileage figures or parking locations, make prices harder to compare. Enter the same accurate details every time.

Build up a no-claims discount

Years of claim-free driving build a no-claims discount that can significantly reduce your premium. Some insurers offer protection for it as an add-on; whether that is worth paying for depends on how many years you have built up and what it costs.

Common mistakes to avoid

• Auto-renewing without checking. Your insurer cannot charge you more than a new customer, but another insurer may be cheaper.
• Quoting too late. Leaving it until the last few days limits your options and often costs more.
• Choosing monthly without comparing the annual total. The interest can add a significant amount over the year.
• Entering inconsistent details. If your address, mileage or job title differs between quotes, you are not comparing like with like.
• Focusing only on price. Check what is covered, including the excess, courtesy car, legal expenses and breakdown cover.
• Ignoring direct-only insurers. Some insurers do not appear on comparison sites.

What not to do

These can leave you uninsured, void your policy or land you in legal trouble:

• Do not understate your mileage. If you drive significantly more than you declared, your insurer could refuse a claim.
• Do not use the wrong address. Using someone else's address to get a cheaper quote is fraud.
• Do not hide modifications. Changes to the car, from alloy wheels to engine remaps, must be declared.
• Do not list a false main driver. Naming someone else as the main driver when you are the main user is called fronting. It is a form of insurance fraud and can invalidate your cover.
• Do not let your policy lapse. Driving, or keeping a car on the road, without insurance is illegal, and a gap in cover can make future insurance more expensive.

The bottom line

Cheaper car insurance is rarely about one trick. It is the combination of comparing widely, quoting at the right time, giving accurate details and understanding what drives the price. The most important habit is not to auto-renew without checking.
