When things change, remember to update your car insurance details

Moving house, starting a new job or changing your name? Car insurance might be the last thing on your mind. But it’s important to let your insurer know if your details change.

Not sure what details you need to let your insurer know about? Find out more in our guide.

    Why it’s important to keep your car insurance details up to date

    Your car insurance is based on the details you give when you take out a policy. So, if your details aren’t correct, it could change how your policy works.

    In some cases, it could mean any claims you make will take longer. And in others, it could invalidate your policy - and leave you uninsured.

    Keeping everything up to date helps your insurer provide the right level of cover for your needs. And letting them know about any changes as soon as possible will keep your insurance valid and avoid delays.

    Remember that changing your details won’t always change your car insurance policy or cost.

    You can check your Tesco Car Insurance policy booklet anytime in ‘Your Insurance Account’ to make sure everything is correct.

    You can easily make changes and update your personal details online. Simply click the sign in button and make the changes instantly.

      Note, if your policy is due for renewal, you’ll not be able to make changes to it in Your Insurance Account until it renews.

        What changes do you need to tell your insurer about?

        It’s your responsibility to make sure your car insurance details are up to date. If any of these details change, you should contact your insurer as soon as possible to let them know.

          Your address

          Your address is crucial in deciding how much your car insurance premium will be. That’s because some postcodes are considered more high-risk than others. If you live in a high-risk area, your premium is likely to be higher.

          You should let your insurer know if you change:

          • your home address - if you move homes or change your permanent address, tell your insurer as soon as you can. This will make sure you’re covered as soon as you move. You might need to provide proof of your new address, like a mortgage statement or utility bill.your home address - if you move homes or change your permanent address, tell your insurer as soon as you can.

          What if anything changes for named drivers?

          It’s not just your personal details that matter. If you have any named drivers on your policy, you should also let your insurer know if anything changes to their details. This might include:

          • their name or gendertheir name or gender
          • occupationoccupation
          • passing a driving testpassing a driving test
          • how often they drivehow often they drive
          • any convictions or claimsany convictions or claims

          If someone new is going to drive your car on a regular basis, it’s important to add them as a named driver to your policy. Adding a named driver can increase but also decrease the policy cost.

          Your premium will be recalculated based on their age, driving experience, claims history, driving convictions and occupation.

          Remember, the main driver must be the person who uses the car the most. If a higher-risk driver is listed as a named driver but is actually the main driver, this is called fronting - which is illegal.

          Find out more about fronting in our guide - What is fronting?

            Do I need to let my insurer know about any driving offences?

            If you commit a driving offence, this could add points to your licence. If that happens, you’ll need to let your insurer know. But you usually only need to do this when it’s time to renew your policy.

            If you receive a driving ban, you’ll need to tell your insurer immediately.

              Will I be charged for changing details on my car insurance?

              Most insurers will charge an administration fee for changing your car insurance details.

              With Tesco Car Insurance, you won’t be charged an admin fee for making a change online in Your Insurance Account.

              But your premium might increase or decrease depending on what the change is. We’ll let you know of any adjustment to your premium or any changes to the terms.

              If you call us to make a change to your policy once it’s started, we’ll charge an admin fee of £25 in addition to any change in premium.

              Find out more about changing your policy in our Car Insurance FAQs.

                Can I add optional extras to my policy when making a change?

                Yes, you can add optional extras to your car insurance policy at any time - either online via Your Insurance Account, or by giving us a call.

                You can choose from the following add-ons:

                  Don’t forget to update your driving licence, too

                  It’s also important to update your driving licence details at the same time. That’s because the information on your licence should match what’s on your car insurance policy.

                  To change your personal details on your driving licence, you’ll need to contact the DVLA. You can do this on the UK Government website - Update your driving licence.

                  You’ll need to let them know if:

                  • you move houseyou move house

                  If you don’t update your driving licence, you could face a fine of up to £1,000.
