How do modifications affect car insurance?

When it comes to modifications to a car, out of third-party liability and a comprehensive car insurance policy, only the latter one gets affected. When you purchase a comprehensive car insurance policy, your car is valued, and the amount of premium is evaluated. So, as you modify your car in any way, the car value may increase. Hence it would be best if you informed your insurer about any car modifications done at your end.

Suppose you fail to inform the insurer and your car suffers damage due to an accident or natural calamity like cyclone , then the insurer has the right to either reject the claim or make a partial payment based on the parts originally covered in the plan and not the modified ones. As you inform the insurer of any modifications, they can re-inspect the car and make the necessary changes in the modified car insurance plan.

Remember, a standard comprehensive car insurance plan does not cover externally-fitted parts meaning the parts that are not fitted by the car manufacturer. However, you can choose to add them to the plan with the help of an add-on for the accessories cover. But keep in mind, this can increase the amount of premium of your plan.

FAQs – Frequently asked questions

Let's take a look at some frequent queries on how will modifications affect my car insurance;

Q1. If I get a paint job done on my car, should I inform my car insurance company about it?

Yes, if you choose an entirely new color for the car or are adding some graphics, you need to inform the insurer about it. If you are simply repainting the car with the same color paint, then it is okay not to notify the insurer as it won't affect the car value in any way.

Q2. Are fully tinted windows permitted in India?

No, fully tinted windows are not acceptable in India. Any car windshield and the rear glass must have at least 70% visibility, and any other windows must have more than 50% visibility as per the law in India.

Q3. If one of the family members has recently suffered a disability, and I modified my car to make it more accessible for the member, then do I need to inform the insurer about such modification?

Yes, it would be best if you informed the insurer about any significant modifications. However, in such cases, it is most unlikely that such change will increase the premium. Primarily in such cases, insurers tend to decrease the premium. But don’t forget to read the terms and conditions of the modified plan carefully.

Q4. If I wish to cover my car with graffiti, in that case, do I have to inform the insurer, and will it increase my car insurance premium?

No, your car insurance premium may not get affected by such modification. However, it is best to inform your insurer of any change done to your car to avoid any hassle later or during the time of claim.

Q5. In case the insurer is unaware of any car modifications, what happens?

On verification and checking a car value, an insurance company drafts your car insurance policy and premium amount. In case any modification is done that changes the value of the car, at the time of claim, the insurer will inspect the car. If there are any significant changes that were uninformed, they have the right to reject the insurance claim as it changes the value of the car and its premium amount.
