Insuring a CNG-Powered Vehicle: Adding CNG to Your Car Insurance

More and more people are moving towards environmentally conscious practices by taking public transport over private ones and switching to CNG vehicles.

Further, compressed natural gas is the best alternative to petrol because it is comparatively cheaper than its counterparts. Moreover, the level of carbon dioxide and other harmful emissions is low, which makes it environmentally friendly as well.

 If you are exploring a car insurance online plan for your new CNG vehicle,  or plan to install a CNG kit, there are a few points that must be taken into consideration. Firstly, having CNG car insurance is mandatory. Further, opting for comprehensive car insurance is always a wise decision regardless of your vehicle’s fuel type.

 How to Get CNG Installed in Your Car?

There are two ways in which you can get a CNG-based car:

1.       Externally get your CNG installed

2.       Purchasing a CNG-fitted Car

You can buy a new car which already has a CNG kit installed by the manufacturer. This means that at the time of purchase of your new insurance policy, the insurance provider is aware of the CNG fitting and offers coverage accordingly.

Difference Between Externally Fitted CNG Car Insurance VS Internally Fitted CNG Auto Car Insurance

Factors External CNG Fitted Kit Internal CNG Fitted Kit
Coverage When you get an external CNG kit installed on your existing car, your existing insurance may need to be revised.

Installations may increase maintenance costs, and repair expenses may also get higher.

Therefore, to ensure you have optimum comprehensive coverage, you need to inform your insurer and expand your current policy to include the externally fitted  CNG kit.

Internal CNG kits are factory-fitted, which automatically covers them in the insurance plan for the entire vehicle.

You won’t need separate coverage as the kit is considered an integral part of the original vehicle configuration.

Premiums For external CNG installations, premiums are impacted significantly. There is a fixed liability premium of Rs. 60 (subject to change) for externally fitted CNG cars as per IRDAI.

This includes the premiums for Own Damage, resulting in higher overall insurance costs compared to petrol or diesel vehicles.


The cost of an internal CNG Kit is less expensive as compared with an externally added kit.


Endorsement Requirement Installing an external CNG kit is an alteration to the vehicle. Therefore, you need to request an endorsement for the CNG kit from your insurer.

Please do so to avoid the rejection of claims related to accidental damage involving the CNG kit.

Internal CNG kits do not require a separate endorsement as they are part of the original vehicle configuration.
Claim Rejection Risk You may face a risk of claim rejection if you have an external CNG kit that is not endorsed. With internal CNG installations, there is no specific risk of claim rejection related to the CNG kit, as it is considered a part of the original vehicle configuration.


When you choose a CNG for your car, it means you are ready to put your money into a green and safe future. All you have to do is make sure that your CNG kit is correctly installed if you are externally installing it. Further, make sure you purchase a car insurance policy and inform your insurance company accordingly, as it is crucial not only for your personal safety but also for your financial safety.
