Motor NCB Not Transferred or Wrongly Removed? Here Is How to Fix It

Who this guide is for

This guide is for any motor insurance policyholder in India who has run into one of these situations:

• Zero NCB on renewal despite no claims: Your renewal notice or quote shows no NCB discount, even though you did not make a claim in the previous policy year or in several preceding years.
• NCB lost after switching insurer: You moved to a new insurer at renewal but did not know you needed to submit an NCB certificate, so your accumulated discount was ignored.
• NCB not retained after selling your old vehicle: You sold your car or bike, bought a new one, and discovered the years of discount you earned on the old vehicle were not applied to the new policy.
• NCB reduced or downgraded without explanation: Your insurer applied a lower NCB slab than the one shown on your previous policy, possibly because of an administrative error or a disputed claim.
• NCB protection add-on not honoured: You had purchased an NCB protection rider, made one claim, but found your NCB was reset to zero at renewal anyway.

This guide covers own-damage (OD) motor policies — comprehensive car and two-wheeler insurance. Third-party-only policies do not carry an NCB component. The guide applies to both private and public sector general insurers, with a note on where the RTI Act can help.

What you can do this weekend

Friday evening

Pull out every motor insurance document you can find. You need your current renewal quote or renewal notice, your previous policy schedule (the one that just expired or the one before that), and — if you switched insurers or sold a vehicle — the NCB certificate your old insurer issued. Open your email inbox and search for "NCB", "no claim bonus", "renewal", and your insurer's name. Download and save everything in one folder. If you do not have a digital copy, call your insurer's customer care line and ask them to email you a duplicate policy schedule and a copy of your claims history for the last three to five years.

While you are at it, check your renewal quote carefully: the NCB percentage shown should match the slab you have earned. Cross-reference it with the NCB table printed on your old policy or the IRDAI Motor Insurance Handbook (available on irdai.gov.in). If the numbers do not match, note the discrepancy in writing.

Saturday

Draft and send your written complaint to the insurer's Grievance Redressal Officer (GRO). Every general insurer licensed by IRDAI is required to have a GRO and to publish their contact details on their website and on every policy document. Address your email to the GRO, not to a generic customer care inbox, so that the statutory 15-day response clock starts ticking. Use the template in this guide (below) as your starting point. Attach:

• Your previous policy schedule showing the NCB earned
• Your current renewal quote or notice showing the wrong (lower or zero) NCB
• Any NCB certificate you hold
• A brief, factual timeline of your claim-free years

Send the email and keep the sent-mail copy. If the GRO email bounces or is not available, send a hard copy by registered post and keep the postal receipt.

Sunday

If your renewal date is very close and you cannot afford to wait for the GRO reply, you may need to renew first and dispute the NCB separately. Renewing without the correct NCB does not waive your right to a refund of the overcharged premium later — note this explicitly in your renewal communication. Separately, take 30 minutes to create an account on the Bima Bharosa portal (bimabharosa.irdai.gov.in) and familiarise yourself with the complaint registration form. If the GRO does not respond within 15 days, you are ready to escalate immediately.

Documents and evidence checklist

Step-by-step action plan

Understanding how NCB works before you dispute

NCB is a discount on the own-damage (OD) portion of your motor premium — not on the third-party premium, which is fixed by IRDAI tariff. IRDAI has standardised the NCB slab structure: slabs progress year by year, with a cap at 50% of the OD premium after five or more consecutive claim-free years. No insurer can offer more or charge less. The exact percentages for each year of claim-free driving are printed in the IRDAI Motor Insurance Handbook and on your renewal notice — check those documents rather than relying on informal summaries.

Key rules to know:

• NCB belongs to you, not to the vehicle. If you sell your car, the NCB stays with you. The new owner cannot claim your NCB history.
• NCB transfers when you switch insurer at renewal. You must obtain an NCB certificate from your outgoing insurer and submit it to the new insurer. Without this certificate, the new insurer may default to zero NCB.
• NCB resets to zero if the policy lapses for more than 90 days without renewal, or if you make a claim (unless you have a valid NCB protection add-on).
• NCB certificate is valid for three years. If you have sold a vehicle and not yet bought a new one, you have up to three years to use the certificate on a new policy.
• If you switch mid-policy, you forfeit that year's NCB accrual. Switch only at renewal to preserve it.

Step 1 — Confirm the error with evidence

Compare the NCB shown on your old policy schedule (the one just expired) with the NCB shown on the current renewal quote. If the old policy shows, say, a three-year NCB slab and the new quote shows zero or a lower slab, you have a clear discrepancy to dispute. Write down the two numbers, the policy numbers, and the dates. This is your core evidence.

If you switched insurer and have an NCB certificate, check whether you actually submitted it to the new insurer. If you did not, the insurer may have applied zero NCB legitimately — in which case your task is to submit the certificate now and ask for a corrected quote or a premium refund.

Step 2 — Write to the Grievance Redressal Officer (GRO)

Every IRDAI-licensed general insurer must have a GRO. Find the GRO's email address on your policy document, on the insurer's website under "Grievance" or "Contact Us", or on the IRDAI consumer portal at policyholder.gov.in. Send a clear, factual email (use the template below) attaching your evidence. State the relief you want: correction of the NCB slab and, if you have already renewed at the wrong rate, a refund of the excess premium charged.

Keep the email brief and factual. Avoid emotional language. The GRO is a statutory channel and is more effective than a general customer care call.

Step 3 — Give the insurer 15 days to respond

IRDAI regulations require insurers to acknowledge complaints promptly and resolve them within 15 days. Mark your calendar. If you receive a satisfactory correction within 15 days, request a revised policy endorsement in writing confirming the corrected NCB and any premium adjustment. Keep this for your records.

Step 4 — Escalate to IRDAI via Bima Bharosa

If the insurer does not respond within 15 days, or responds but rejects your complaint without adequate explanation, register a grievance on the Bima Bharosa portal at bimabharosa.irdai.gov.in. You can also email [email protected] or call the toll-free number 155255 (or 1800 4254 732). When registering online, you will receive a token number — note it carefully, as it allows you to track and reopen your complaint.

Attach the same evidence package you sent the GRO, plus a copy of the GRO complaint and their response (or a note that they did not respond). IRDAI will take up the grievance with the insurer on your behalf.

Step 5 — Approach the Insurance Ombudsman

If the IRDAI escalation does not produce a satisfactory resolution, file a complaint with the Insurance Ombudsman (Bima Lokpal) for your region. Complaints can be filed through the Council for Insurance Ombudsmen portal at cioins.co.in, by post to the relevant Ombudsman office, or by email. The service is completely free. The Ombudsman can pass a binding award requiring the insurer to correct your NCB and refund any excess premium. The compensation limit for non-life insurance disputes handled by the Ombudsman is Rs. 50 lakh.

You must file with the Ombudsman within one year of the insurer's final rejection (or within one year of the end of the 30-day window if the insurer gave no reply at all).

Step 6 — Consumer forum as a last resort

If the Ombudsman route does not resolve the matter, or if the value at stake exceeds the Ombudsman's jurisdiction, you may file a complaint before a Consumer Disputes Redressal Commission under the Consumer Protection Act, 2019. See our guide on how to file a consumer court complaint in India for the full process.

When RTI can help

The Right to Information Act, 2005 applies to public authorities as defined under the Act. In the general insurance sector, the four major public sector general insurers — New India Assurance Company, Oriental Insurance Company, National Insurance Company, and United India Insurance Company — are public authorities for the purpose of RTI.

If your NCB dispute is with one of these public sector insurers, you can file an RTI application with the insurer's Public Information Officer (PIO) to obtain:

• Your complete claims history for the policy years in dispute
• The NCB calculation applied to each renewal, and the official basis for any reduction or removal
• Copies of any internal communications or instructions that led to your NCB being changed
• The insurer's internal policy or guidelines on NCB correction and reinstatement

This information can be powerful evidence if you subsequently escalate to the Ombudsman or a consumer court. File your RTI online at rtionline.gov.in or by post to the PIO of the relevant insurer. If your first RTI is denied or only partially answered, you can file a first appeal under Section 19 of the RTI Act. For a deeper understanding of the RTI process, the RTI Playbook is a useful reference.

When RTI will not help

Private general insurers are not public authorities. You cannot file an RTI application against ICICI Lombard, HDFC Ergo, Bajaj Allianz, Tata AIG, Reliance General, Navi, Acko, Go Digit, or any other private insurer. RTI simply does not apply to them.

For disputes with private insurers, your forums are: the insurer's own GRO, then IRDAI (Bima Bharosa), then the Insurance Ombudsman, and finally the consumer courts. These channels are described in the escalation ladder above. They are all free or very low cost, and the Insurance Ombudsman in particular can issue binding orders.

IRDAI itself, as a statutory regulator, is a public authority under the RTI Act. However, RTI to IRDAI is more useful for obtaining copies of circulars, regulations, or policy interpretations — it is generally not the right tool for resolving a specific billing dispute with an individual insurer.

Common mistakes to avoid

• Not requesting an NCB certificate when switching insurer. This is the single most common reason NCB is lost. When you move to a new insurer at renewal, you must proactively request an NCB certificate from the outgoing insurer and submit it to the new one. The new insurer will not automatically know your claims history.
• Assuming NCB transfers with the vehicle when you sell it. It does not. NCB stays with you. Ask your insurer for an NCB retention certificate before or soon after selling. The certificate is valid for three years — use it when you insure your next vehicle.
• Letting the policy lapse for more than 90 days. If your comprehensive policy is not renewed within 90 days of expiry, your accumulated NCB is forfeited. Always renew on time, even if you plan to switch insurer.
• Renewing without checking the NCB figure first. Once you renew and pay, it becomes harder (though not impossible) to get a refund. Always check the NCB shown on the renewal quote against your previous policy before paying.
• Making a claim without checking NCB impact. For small repair amounts, the NCB you would lose can be worth more than the claim itself. Calculate whether it makes sense to pay out of pocket and preserve the NCB. Use the NCB slab table on your renewal notice to estimate the saving over the next few years.
• Buying an NCB protection add-on and assuming it is unlimited. NCB protection typically covers a specified number of claims per policy year. Read the terms carefully — it does not protect you against every possible scenario, and the exact terms vary by insurer.
• Escalating to IRDAI or the Ombudsman without first complaining to the GRO. Both IRDAI and the Ombudsman will ask whether you have first raised the matter with your insurer's GRO. Skipping this step wastes time. The GRO complaint is the mandatory first step.
• Missing the one-year deadline for the Ombudsman. You must approach the Insurance Ombudsman within one year of the insurer's final rejection (or, if there was no reply, within one year of the end of the 30-day response window). Set a reminder.
