NCB Protection

NCB protection is an optional add-on cover in motor (car and two-wheeler) insurance that safeguards your No Claim Bonus. The No Claim Bonus is a discount you earn on your own-damage premium for every claim-free year. Without protection, a single claim usually resets this hard-earned discount back to zero at renewal. The NCB protection add-on lets you make a limited number of claims while keeping the bonus intact.

How it works

In India, NCB starts at 20% after the first claim-free year and steps up in slabs to a maximum of 50% after five consecutive claim-free years. The discount applies only to the own-damage part of the premium, not the mandatory third-party liability premium. Importantly, NCB belongs to the policyholder, not the vehicle, so it can be carried over when you change cars or insurers.

With the NCB protection add-on, you typically pay a small extra premium and are then allowed a permitted number of own-damage claims, often up to two per policy year, without losing your NCB slab. The exact number of permitted claims and the conditions are set by the insurer within IRDAI norms, so read the policy wording.

In India

NCB slabs are standardised under IRDAI guidelines and apply across insurers, though the protection add-on itself is a paid optional cover. A key rule: NCB is preserved only if you renew the policy within the allowed grace period after expiry, generally 90 days. Let the policy lapse beyond that, and you can lose the accumulated bonus entirely.

Why it matters

For someone with a long claim-free record, a 50% NCB is a substantial saving. One unlucky claim, say a minor accident, could otherwise wipe that out. The add-on is most valuable for drivers with a high NCB slab who want the freedom to claim for genuine damage without being penalised.

Common mistakes

Drivers often forget that NCB protection does not cover unlimited claims, exceed the permitted number and you still lose the bonus. Others let the policy lapse and lose NCB for missing the renewal window. Also remember the bonus follows the person: declare your existing NCB correctly when switching insurers to keep your discount.
