NCB Transfer in Car Insurance: 7 Powerful Steps to Save Up to 50%
Everything you need to know about transferring your No Claim Bonus when you switch cars or insurers — without losing a single rupee of discount.
NCB Transfer in car insurance is one of the most valuable yet misunderstood benefits available to Indian motorists. The No Claim Bonus (NCB) is a reward from your insurer for driving safely and not filing any claims during a policy year — and the good news is, it belongs to you, not the car or the insurer. That means when you upgrade your vehicle or switch insurance providers, you can legally transfer your NCB and continue saving up to 50% on the own-damage premium of your new policy.
In this comprehensive guide, we'll walk you through how NCB works, how much you can save, the exact documents required, and a step-by-step process to transfer your NCB the right way in 2026 — backed by IRDAI guidelines and the experience of the Aero Insurance advisory team.

Talk to an Aero Insurance ExpertWhat Is No Claim Bonus (NCB)?
The No Claim Bonus is a discount offered on the own-damage (OD) portion of your car insurance premium when you complete a full policy year without filing a claim. It is regulated by the Insurance Regulatory and Development Authority of India (IRDAI) and follows a standardized slab structure across every general insurer in the country.
The discount accrues year after year, starting at 20% after the first claim-free year and reaching a maximum of 50% after five consecutive claim-free years. Think of it as a loyalty reward from the insurance ecosystem for being a responsible driver.
When Can You Transfer Your NCB?
There are three common scenarios where an NCB transfer is applicable:
1. Switching Insurance Companies
If you move from Insurer A to Insurer B at renewal, your NCB travels with you. You simply need to declare it during the new proposal and submit the supporting documents.
2. Buying a New Car
When you sell your old vehicle and purchase a new one, the NCB earned on the old car can be transferred to the new car's policy — even if the new car is from a different segment.
3. Inheriting a Vehicle
If a car is transferred to a family member (for example, through a legal transfer or gift), the original owner's NCB can be retained on a separate NCB certificate and used on their next vehicle.
How to Transfer NCB in Car Insurance: 7 Step-by-Step Guide
- Check your existing NCB percentageYour current policy document will clearly state the NCB slab you are on (20%, 25%, 35%, 45%, or 50%). Confirm this before you begin the transfer.
- Request an NCB Reservation Letter or CertificateAsk your existing insurer to issue an NCB Reservation Letter — valid for three years from the date of sale of the old vehicle.
- Complete Form 28, 29 & 30 for vehicle saleThese RTO forms formalize the transfer of vehicle ownership. They are essential evidence that you sold your old car and are eligible for a fresh NCB transfer.
- Collect proof of new vehicle purchaseKeep your new car's invoice, RC copy (or order confirmation), and chassis/engine number handy for the proposal form.
- Declare NCB on the new proposal formWhen buying the new policy, truthfully declare your earned NCB percentage and upload the reservation letter at the proposal stage.
- Insurer verifies and applies the discountThe new insurer cross-verifies your NCB with the previous insurer or the IIB (Insurance Information Bureau) database and applies the discount on your OD premium.
- Receive your new policy with NCB appliedReview the final policy copy and ensure the NCB discount is reflected in the premium calculation. Save it for future renewals.

Common Mistakes to Avoid
Even seasoned policyholders lose their NCB by making small oversights. Watch out for these:
Letting the three-year window lapse
An NCB Reservation Letter is valid for only three years from the date your old policy expires or your old car is sold. If you don't buy a new policy within that window, your accumulated NCB is permanently lost.
Filing a small claim
A single claim resets your NCB to zero at renewal. Before raising any claim, calculate whether the repair cost is actually higher than the NCB discount you'd lose over the next two years.
Not declaring NCB truthfully
Over-declaring can lead to policy cancellation or claim rejection at the worst possible moment. Always declare the exact percentage reflected on your certificate.

NCB Protection is an add-on cover that lets you file up to one or two claims in a policy year without losing your hard-earned NCB. If you drive in high-traffic metros like Mumbai, Bengaluru, or Delhi — or your car has expensive OEM parts — this add-on typically pays for itself within the first claim.

Frequently Asked Questions
Can I transfer my NCB if I've been without insurance for a few months?
Yes. The NCB Reservation Letter remains valid for three years from the expiry of your last policy. As long as you buy a new policy within this window, you retain your NCB.
Is NCB transferable between two-wheeler and four-wheeler policies?
No. NCB is class-specific. A private car NCB can only be transferred to another private car, and a two-wheeler NCB only to another two-wheeler.
Does NCB apply to third-party premium?
No. NCB is calculated only on the Own Damage (OD) component of your comprehensive policy. Third-party premium is fixed by IRDAI and not discount-eligible.
What happens to my NCB if the claim was raised by a third party?
If the claim is a third-party-only claim and no own-damage claim was filed, your NCB is preserved at renewal.
Can I transfer NCB online?
Yes. Most insurers — and brokers like Aero Insurance — allow fully digital NCB transfers. You upload the reservation letter and supporting documents during the proposal stage.
Will I lose my NCB if I port to a new insurer?
Absolutely not. Porting between insurers does not affect your NCB — as long as you declare it correctly and submit the reservation letter from your previous insurer.
