Car Insurance Renewal: The Add-ons Worth Buying

By Lokesh Attoor aka Loki

Why add-ons matter at renewal

A comprehensive policy alone leaves big gaps in what you actually get paid at claim time. Depreciation cuts, engine damage from water, consumables and total-loss shortfalls are all excluded or reduced in the base cover.

Renewal is the cheapest and easiest moment to fix this. Most add-ons can only be bought with the policy, not mid-term, and some (like zero depreciation) are refused once the car crosses an age limit or the cover has lapsed. A few hundred to a few thousand rupees more in premium can save tens of thousands on a single claim.

The add-ons worth buying

Five add-ons do most of the work: zero depreciation, engine protection, return to invoice, consumables and roadside assistance. The rest are situational.

Add-on What it pays for Who needs it Approx. cost
Zero depreciation (unlimited claims variant if available) Full cost of replaced parts, no depreciation cut on plastic, rubber, fibre or metal Every car under 5 years; essential in city traffic 10–20% of own-damage premium
Engine protection Engine and gearbox damage from water ingress, oil leakage, hydrostatic lock Flood-prone cities, low-slung cars ₹500–2,500
Return to invoice (RTI) Gap between IDV and on-road price (incl. registration, road tax) on theft or total loss Cars under 3 years, high theft risk models ₹1,000–4,000
Consumables cover Engine oil, coolant, nuts, bolts, grease, AC gas, bearings used during repair Anyone with zero dep; closes the last out-of-pocket gap ₹300–1,500
Roadside assistance (RSA) Towing, flat tyre, battery jump-start, fuel delivery, lockout Highway drivers, long commutes ₹100–500
NCB protection Keeps your No Claim Bonus after one or two claims Cars with 35–50% NCB built up 5–10% of own-damage premium
Key and lock replacement Cost of lost or stolen smart keys and lock sets Cars with expensive keyless fobs ₹200–600
Tyre protection Tyre and tube damage from bulges, cuts, bursts without an accident Premium tyres, bad roads ₹500–1,500
Personal belongings Laptops, phones, bags stolen from the car Frequent carriers of valuables ₹100–300

Costs are indicative ranges for a mid-size car and vary by insurer, city and car value; check your quote.

In many insurers’ packages, zero dep, consumables and engine protection are sold together as a “bumper-to-bumper” bundle. The term has no standard definition, so check exactly which add-ons the bundle contains.

Limited vs unlimited claims

Zero depreciation add-ons come in two forms. Limited plans cover a fixed number of claims per policy year, most commonly 2; after that, normal depreciation applies again. Unlimited plans waive depreciation on every admissible claim in the year, usually for a slightly higher premium.

Policy documents often don’t make this clear. The schedule may list the add-on only as “Zero Depreciation” with no claim count, and the customer information sheet may simply refer you to the policy wordings. If the limit isn’t stated, assume it is capped.

Verify with your insurer before renewal:

  • Ask in writing how many zero depreciation claims your plan allows per policy year, quoting your policy number and the add-on’s UIN from the schedule.
  • Ask for the add-on’s policy wording and read the clause that sets the claim limit.
  • If you want unlimited claims, request that variant by name and confirm it appears on the new schedule before you pay.
  • Keep the insurer’s written reply with your policy documents.

Whichever plan you have, every claim reduces your No Claim Bonus unless you also hold NCB protection. For small repairs, compare the bill with the NCB you would lose before filing.

Which add-ons for your car’s age

The older the car, the fewer add-ons insurers will sell and the less value they give.

Car age Buy Optional Usually skip
0–3 years Zero dep (unlimited if offered), engine protect, RTI, consumables, RSA NCB protect, key replacement, tyre protect —
3–5 years Zero dep, engine protect, consumables, RSA NCB protect, RTI (if still offered) Tyre protect
5–7 years Zero dep (if insurer allows, at higher cost), engine protect, RSA Consumables RTI, key replacement
7+ years RSA, engine protect (if offered) Personal accident cover upgrades Zero dep (rarely available), RTI

If you live in a flood-prone city, keep engine protection at every age it is offered. Water-damaged engines are the costliest common claim that the base policy refuses.

What people should know before renewing

  1. Renew before expiry. A lapsed policy can mean a fresh vehicle inspection, loss of NCB after 90 days, and insurers refusing zero dep on renewal.
  2. Zero dep does not mean zero cost. You still pay the compulsory deductible (usually ₹1,000–2,000), and consumables unless you have that add-on.
  3. Check the IDV. Insured Declared Value is the maximum payout on total loss or theft. A low IDV lowers the premium but shrinks your payout; don’t accept a cut you didn’t ask for.
  4. Your NCB belongs to you, not the car or insurer. You can carry it to a new insurer when switching, and even to a new car if you sell the old one (get an NCB retention letter).
  5. Know the exclusions. Add-ons do not pay for mechanical breakdown, normal wear and tear, drunk or unlicensed driving, or using a private car commercially.
  6. Engine damage from cranking a flooded car is the most common rejected claim. Never start a car that has stood in water; call the insurer and get it towed. Even engine protect may be denied if you crank it.
  7. Check the cashless garage network. Confirm your usual service centre and nearby garages are on the insurer’s cashless list before you buy.
  8. Compare total cost, not headline premium. Compare the same IDV, the same add-ons and the same claim limits across insurers; cheap quotes often drop an add-on or lower the IDV.
  9. Read the policy schedule on arrival. Confirm every add-on you paid for is listed, along with the claim limit for zero dep and your correct NCB percentage.
  10. Don’t over-claim. For minor damage, compare the repair bill with the NCB you would lose before filing.

Renewal checklist

  • Renew at least 1–2 weeks before the expiry date
  • Confirm the IDV is close to the car’s current market value
  • Zero depreciation added, with the claim limit (2 or unlimited) confirmed in the schedule
  • Engine protection added (essential in flood-prone cities)
  • Consumables cover added
  • Return to invoice added if the car is under 3 years old
  • Roadside assistance added
  • NCB protection considered if NCB is 35% or higher
  • Correct NCB percentage shown on the new policy
  • Usual garage confirmed in the cashless network
  • Quotes compared on the same IDV and add-ons across at least 3 insurers
  • Policy schedule checked on arrival for every add-on paid for
