Car Insurance for Modified Vehicles: What You Need to Know
Making modifications to your vehicle can improve its personality, but it also affects how your insurer evaluates it. Knowing how each modification impacts your premium, risk classification, and claim eligibility is more important than just listing your improvements on your Car Insurance plan. Every modification, whether it's adding alloy wheels, upgrading to a CNG kit, or installing a high-performance sound system, may affect your coverage.
Insurance companies in India closely scrutinise vehicle modifications as they may raise the risk of theft, damage, or misuse. This is why premiums can rise and the IDV for modified cars needs recalculating. If you’re wondering how to insure a modified car, this blog breaks it down clearly.

What Is Modified Car Insurance?
Modified Car Insurance refers to a policy that takes into account non-factory changes made to a vehicle. These modifications could be:
Key factors influencing premiums:-
Performance modifications like adding turbochargers, engine remapping, and suspension upgrades.
-
Aesthetic modifications, including body kits, spoilers, alloy wheels, and custom paint.
-
Functional modifications, like infotainment systems, anti-theft devices, and the installation of CNG or LPG kits.
Policyholders are encouraged to notify their insurer of such changes, as per the IRDAI. By doing this, you can ensure that your coverage remains in effect and that the IDV for the modified car is updated accordingly. Failure to report such significant changes may affect the processing or settlement of a claim. This is where customised Car Insurance comes in, providing tailored coverage for certain kinds of cars.
How Do Modifications Affect Insurance Premiums?
Insurers calculate premiums based on risk, and car modifications can raise or lower that risk.
Key factors influencing premiums:
1. Type of modification
Performance upgrades (e.g., engine tuning) usually raise premiums due to increased speed and accident risk. Safety additions like certified anti-theft devices may reduce premiums.
2. Value increase
Modifications can raise the IDV for modified cars, which means higher coverage but also a higher premium.
3. Likelihood of theft
High-end rims, custom interiors, or rare accessories are attractive to thieves, which increases the insurer’s liability.
4.Regulatory compliance
The only modifications deemed legal are those authorised by the Automotive Research Association of India (ARAI). Any unauthorised or unlawful modifications may render your Car Insurance invalid.
How insurers assess risk:
Insurance companies assess the reported modifications by:
-
Examining the images and modification expenses.
-
Consulting surveyors or engineers for high-priced upgrades.
-
Modifying the IDV and re-evaluating the parameters of coverage.
Modifications that go unreported may lead to partial settlements or outright rejections of claims. Be open and honest about your changes at all times.
How To Get The Right Insurance For Your Modified Car
Taking these important steps can help you get the right Car Insurance for customised vehicles:
1. Keep track of and record all changes
Keep all invoices, certifications, and receipts for all modifications. These act as evidence and aid in determining an updated IDV for the car.
2. Pick an insurance provider who is well-versed in customised cars.
Certain insurance companies are more qualified to evaluate and insure customised vehicles. Although the majority of regular policies could restrict coverage, some companies provide customised plans.
3. Get the modifications endorsed
Notify your insurance company and make sure your policy has an endorsement added. The insured value now includes the modification, which is acknowledged by this endorsement.
4. Evaluate IDV adjustments
Request a revised IDV for modified cars from your insurance provider. In the event of complete loss or theft, an accurate IDV guarantees an appropriate reimbursement.
5. Opt for add-ons
For better protection, choose add-ons like:
-
Zero Depreciation cover (to protect modified parts)
-
Engine Protection cover
-
Personal Belongings cover
Tips to reduce premium:
-
Install security devices authorised by ARAI.
-
Limit your modifications to practical rather than aesthetically pleasing ones.
-
Steer clear of performance or race-style modifications that imply significant risk.
-
Keep accurate service logs and pictures of any modifications.

No. While performance upgrades may raise premiums, safety-related modifications like ARAI-approved, anti-theft devices can sometimes lower them.

Your claim could be rejected, or you may receive only partial compensation. Disclosure is critical for valid coverage.
3. Are there insurers that specialise in modified car coverage?
Yes. While most general insurers provide standard plans, some are better equipped to handle customised vehicle assessments and can tailor coverage accordingly.
4. Will adding a CNG kit affect my premium?
Yes, slightly. However, if the kit is ARAI-approved and declared, most insurers will endorse it with a marginal increase in premium.
