How To Change Your Car Insurance Policy
To change your car insurance policy, contact your insurer, request a mid-term adjustment, and confirm how the update affects your premium and cover.
Most changes can be made during your policy term without cancelling. Your insurer recalculates the premium based on the updated details and applies the change from an agreed date.
If your circumstances have shifted enough to put you in a different risk category, it may be cheaper to cancel and start fresh. Understanding what your policy covers helps you decide which route to take.
Mid-term changes cost around £25 in admin, but the premium recalculation can sting. Before accepting, check prices elsewhere. If you do switch, make sure the saving outweighs any lost no-claims bonus from cancelling before renewal.
Always compare car insurance quotes before accepting a revised premium.

What does changing your car insurance policy mean?
It means making an official update to your insurer that alters your current cover, your premium, or both.
Mid-term adjustment vs new policy
A mid-term adjustment lets you update details like your address, vehicle, or named drivers without ending the contract. Most insurers charge an admin fee of around £25 for this.
If the change is large enough to shift your risk category, your insurer may suggest taking out a new policy instead. This is common when swapping to a much higher-value car.
How do you change your car insurance policy?
Call your insurer or use their online portal to request the change. Have your policy number and the new details ready before you start.
The process step by step
Tell the insurer exactly what has changed and when you want the update to take effect. They will recalculate your premium and confirm the new figure.
If the revised premium seems high, get a comparison quote before accepting. Our tips to lower your car insurance premium can help you negotiate or find a better deal.
Ask for written confirmation once the change is applied. A verbal agreement from a call handler will not help if the policy document has not been updated.
Why would you need to change your car insurance policy?
You need to update your policy whenever something changes that affects how, where, or by whom the car is used.
Common triggers for a policy change
| Change | Typical effect on premium | Action needed |
| New vehicle | Higher or lower depending on insurance group | Notify insurer before driving the new car |
| Change of address | Up in high-theft areas, down in low-claim areas | Update insurer and DVLA |
| Adding a young driver | Usually increases premium | Add as named driver on your policy |
| Change of job or commute | Varies by job title and mileage | Declare new occupation and usage |
| Vehicle modifications | Often increases premium | Declare all mods, even cosmetic ones |
| Reduced mileage | May reduce premium | Update estimated annual mileage |
If you have changed how the car is used, check whether your current class of use still applies. Driving for business on a social-only policy can invalidate your cover.
Vehicle modifications that affect insurance must be declared even if they are cosmetic. Undeclared changes can lead to a refused claim.
How does a policy change affect your premium?
Any update to your policy triggers a risk reassessment. Changes that increase perceived risk raise your premium, while those that lower it can reduce the cost.
What moves the price up or down
Switching to a more powerful or expensive car typically increases the premium. Adding a driver under 25 has a similar effect, particularly if they are newly qualified.
On the other hand, reducing your annual mileage, adding security features, or moving to a lower-risk postcode can bring the cost down.
Your excess, coverage limits, and eligibility for add-ons may also change. Always review the full policy schedule after any update.

Should you switch insurers instead of amending your policy?
If the revised premium after a mid-term adjustment is much higher than quotes elsewhere, switching to a new insurer can save you money.
When switching makes sense
Within the first 14 days you can cancel with minimal cost under the cooling-off period. After that, most insurers charge a cancellation fee of around £50.

Watch out for your no-claims bonus. Many insurers only award a full year’s discount if the policy runs to renewal.
Cancelling early may mean that year does not count towards your discount, even if you switch to a new provider.
If the savings from a new policy outweigh the cancellation fee and any lost NCB, switching is worth it. The FCA’s car insurance rules protect your right to cancel at any time.
What mistakes should you avoid when changing your policy?
The biggest mistake is assuming you are covered before your insurer has confirmed the change in writing.
Common pitfalls to watch for
Driving a new car without updating your insurer first leaves you uninsured. Even if the old policy is still active, it covers the old vehicle, not the new one.
Delaying an address update can invalidate a claim. Insurers price partly on postcode, so a move you have not declared changes the risk they agreed to cover.
Accepting a revised premium without shopping around is another common error. A quick comparison can reveal whether you are paying over the odds.
Lowering your premium is often possible with a few simple steps.
If you make a claim shortly after a policy change, keep a record of what was updated and when. Knowing what to do after an accident and having the right documents ready speeds up the process.
Do you need to notify the DVLA when you change your insurance?
Your insurer updates the Motor Insurance Database (MID) automatically, but you must contact the DVLA yourself if your name, address, or vehicle keeper details change.
Who updates what
Insurers must update the MID promptly after any policy change, with most records appearing within seven days. Police and ANPR cameras check this database to confirm a vehicle is properly insured.
If you have changed your address, update both your driving licence and your V5C logbook with the DVLA. If you have sold the car, notify the DVLA so you are no longer recorded as the keeper.
Failing to keep your DVLA records up to date can cause mismatches with your insurance documents. Driving offence codes and penalty points also need to be declared to your insurer if they change during the policy term.
Frequently Asked Questions (FAQs)
Yes, most insurers allow mid-term adjustments for changes like a new car, address, or named driver. An admin fee of around £25 usually applies.
