Tips for saving on car insurance

We all need car insurance, but that doesn’t mean you have to pay more than you need to. This guide explains what affects your premium, and the sensible steps you can take to help manage the cost without cutting corners or compromising your cover.

What affects the cost of car insurance?

Insurers calculate risk when setting the price of your car insurance premium. The higher they judge the risk of you making a claim, the more you’re likely to pay. While different insurers weigh these factors differently, the most common ones are:

  • Your age and driving experience. Newer and younger drivers statistically make more claims, so premiums tend to be higher.Your age and driving experience. Newer and younger drivers statistically make more claims, so premiums tend to be higher.
  • Your claims history. Previous claims – particularly if you’re found to be at fault – increase the perceived risk.Your claims history. Previous claims – particularly if you’re found to be at fault – increase the perceived risk.

Why is it important to give accurate information?

Before looking at ways to save, it’s vital to remember that you must always provide accurate information when taking out or renewing a policy. Providing inaccurate information is misrepresentation, and the consequences can be serious.

    The risk of inaccurate information

    If you make a claim and your insurer finds that the details on your policy don’t match reality – for example, you stated you drive 3,000 miles per year but actually drive 10,000 miles – your claim could be rejected, your policy declared void, or you could be left uninsured. The short-term saving isn’t worth the risk.

    Because of this, to protect yourself and your vehicle, always keep your policy details up to date and describe your circumstances accurately.

      How can shopping around help me find cheaper car insurance?

      • Comparing quotes at renewal is one of the easiest things you can do to avoid overpaying. Insurers price risk differently, which means the same driver with the same car can receive very different quotes from different providers.Comparing quotes at renewal is one of the easiest things you can do to avoid overpaying.

      • Make sure you get quotes a few weeks before your renewal date rather than leaving it to the last moment – auto-renewing without checking can mean missing better pricing.

      Does increasing my voluntary excess reduce my premium?

      Yes, it usually would. Most insurance policies have a compulsory excess (the amount you agree to pay towards a claim before your insurer covers the rest), and allow you to choose an additional voluntary excess on top of this. Increasing your voluntary excess typically lowers your premium.

      This is because you’re taking on more of the financial risk yourself, making the insurer’s risk lower. But if you do make a claim, you’ll need to pay both the compulsory and the voluntary excess. So before increasing your voluntary excess, make sure the amount you choose is really affordable for you.

        Example – weighing up the excess

        You’re renewing your policy. You see you can lower your premium by increasing your voluntary excess. You could comfortably cover the total excess amount from your savings if you needed to claim. So you decide it makes sense for your situation. This wouldn’t be the right call if you had no way of paying for the higher excess.

          Can how I drive affect my insurance cost?

          Yes - your driving record has a direct effect on your premium over time. Avoiding accidents helps you build up a no claims discount (NCD), which can reduce your premium year on year. Find out more about no claims discounts. Motoring convictions can also increase your insurance costs. A long, clean driving record is one of the most effective ways to keep costs down over time.

            Telematics (black box) policies

            If you’re a younger or newer driver, a telematics policy can give you more affordable insurance. A small device or app monitors your driving habits – speed, braking, the times you drive – and safe driving rewards you with a lower premium. These policies are particularly popular with young drivers.

              Advanced driving qualifications

              Some insurers offer a discount to drivers who hold an advanced driving qualification, such as Pass Plus or an IAM RoadSmart qualification. It’s worth checking whether your insurer recognises these, as not all do.

                Does my car choice affect how much I pay?

                Yes, significantly. Every model of car in the UK has an insurance rating decided by a variety of factors including engine size, repair costs, and safety ratings.

                If you’re in the market for a new or used car and cost is a priority, it’s worth checking a car’s insurance rating before you buy. The difference between insurance ratings can be meaningful, particularly for younger drivers where premiums are already higher.

                Does paying annually vs monthly make a difference?

                In most cases, paying annually upfront works out cheaper overall than paying monthly. Monthly payments involve a form of credit, with interest applied – meaning you pay more over the course of the year. If you can afford to pay upfront, that’s usually the most cost-effective option.

                  Are there other ways to reduce the cost of car insurance?

                  Add a named driver carefully

                  Adding an experienced driver with a clean record as a named driver can sometimes reduce your premium – but only if that person genuinely uses the car.

                    Only pay for the cover you need

                    Make sure your level of cover matches your circumstances. Third-party, third-party fire and theft, and comprehensive cover carry different prices. Comprehensive isn’t always the most expensive option, so it’s worth getting quotes at each level.

                    Also review any add-ons at renewal – breakdown cover, legal protection, courtesy car – and remove anything you don’t genuinely need. Learn more about car insurance add-ons.

                    Some insurance providers may offer online-only policies for a cheaper premium. So if you can manage without phone support, this could save you money.

                      Keep your details up to date

                      Changes in your circumstances – a new job, a change of address, or reduced mileage due to working from home – can sometimes affect your premium. Let your insurer know about relevant changes as they happen. Not only does this keep your cover valid, but in some cases it can lead to a lower premium. With Tesco Insurance, changes to your policy can be made fee-free online in Your Insurance Account, helping you keep your costs down.

                        Example - a renewal quote brings a saving

                        Your renewal quote is higher than your previous year’s premium. Rather than just accepting it, you check your policy details. You realise that as you’ve switched to working from home, your annual mileage has dropped. You update your mileage accurately, compare quotes, and increase your voluntary excess to a level you’re comfortable with. Your renewal premium comes in lower than the previous year’s – without changing anything inaccurately.

                          The importance of accuracy

                          The most important thing when managing your car insurance cost is that everything you tell your insurer is accurate and up to date. Genuine savings come from making smart, informed choices – not from adjusting details to get a lower quote. If your circumstances change, let your insurer know. And if you’re ever unsure whether something needs to be declared, just ask to make sure.
