How to avoid costly mistakes at car insurance renewal in 2025

Representative image

Motor insurance renewals often feel routine, but the decisions you take at this stage can quietly increase your premium, weaken your protection or delay claim settlements later. Between IDV values, add-on packages, NCB continuity and documentation rules, many motorists end up renewing on auto-pilot. A careful check at renewal can make the difference between a smooth claim and an expensive surprise.

The confusion around IDV — and what actually matters

Insurers still quote IDV as the “current market value” of your vehicle, but many buyers misunderstand what this number really does. IDV is not the resale price, nor is it the amount you will always receive if your car is stolen or totally damaged. It is only the agreed value used to compute premiums and calculate total-loss payouts.

During renewal, most insurers automatically lower the IDV based on depreciation slabs. A slightly lower IDV reduces your premium but also reduces your maximum claim, especially if the car is stolen or destroyed. Many people assume choosing the highest IDV guarantees a bigger payout. It does not. If you pick an inflated IDV, the insurer can still assess the car’s fair market value at the time of claim. A sensible IDV is the one closest to the actual market price for your model and year — not the highest and not the lowest. Checking online resale benchmarks before renewing helps you avoid being over- or under-covered.

Zero-dep is useful — but not always necessary

Zero-depreciation cover became a default add-on for many because it removes the depreciation cuts applied to plastic, fibre and metal parts during repairs. For new cars or vehicles up to five years old, the benefit is clear: the insurer pays the full cost of part replacement without reducing the claim amount.

However, many people buy zero-dep out of habit even when the car is older or has very low usage. For cars beyond six or seven years, some insurers limit zero-dep or increase its cost sharply. If your car runs very few kilometres, or you rarely raise claims, a standard comprehensive policy with a reasonably-priced add-on like consumables or return-to-invoice might offer better value than a pricey zero-dep extension.

Do not assume all zero-dep policies are identical. Some only allow two claims a year, while others cap the claim amount. Reading these limits is more important than choosing the cheapest option.

The proof you actually need when making a claim

Many claim delays happen because car owners are unsure what documents really matter. At claim time, insurers ask for a few consistent items: RC copy, driving licence, policy document and basic claim forms. Photos and videos taken at the accident spot help speed up approvals. What most people don’t realise is that insurers rely heavily on timestamped visual evidence to rule out staged accidents, pre-existing damage or unrelated dents. A quick set of photos from multiple angles in good light becomes your strongest claim support.

For theft claims, FIR copies and the untraceable report are crucial. For cashless repairs, garages handle most paperwork, but you still need to confirm the surveyor’s inspection time. At renewal, keep digital copies of RC, licence and previous policies organised. This simple step cuts down verification time when you file a claim months later.

NCB continuity and add-ons you can skip

The No Claim Bonus (NCB) often reduces premiums significantly at renewal, but it lapses if you delay renewal beyond the grace period. Many customers lose NCB simply by missing deadlines. If you’re switching insurers, carry the NCB certificate forward — the new insurer must honour it.

Most policies offer add-ons like engine protector, roadside assistance, personal accident cover and key replacement. Engine protection is genuinely helpful in flood-prone cities or for cars with expensive engines. Roadside assistance is worth the small extra cost if your car is older or you travel long distances. Add-ons like key cover or daily allowance are rarely needed and usually inflate premiums without meaningful benefit.

A quick renewal review saves you trouble later

A good renewal is simply a check of four things: a realistic IDV, a sensible set of add-ons, NCB protection and updated documents. These small steps prevent inflated premiums and make claim settlement easier. Instead of renewing automatically, take a few minutes to compare your insurer’s terms with two competitors. The difference in cost and coverage is often significant.

Motor insurance has become more transparent over the years, but the fine print still decides your experience at claim time. Understanding IDV, choosing zero-dep wisely and keeping the right proof ready ensures you stay protected without paying more than you should.

FAQs

1. Does choosing a higher IDV guarantee a higher payout during a claim?

Not necessarily. Even if you pick a slightly higher IDV at renewal, insurers can reassess the vehicle’s fair market value at the time of loss. If the IDV is artificially inflated, they may settle the claim at the actual market price. The best IDV is the one closest to your car’s real resale value for its model and year.

2. Is zero-depreciation cover worth it for older cars?

Zero-dep is most useful for new cars or vehicles up to five years old, where part-replacement costs are high. For older cars, premiums rise and many insurers put limits on the number of zero-dep claims. If your car is six to eight years old or runs very little, a standard comprehensive policy with selective add-ons may be better value.

3. What documents should I keep ready for faster claim approval?

Keep digital copies of your RC, driving licence, insurance policy schedule and previous claim history. At the accident site, take clear photos or videos of the damage and surroundings. For theft claims, FIR and police reports are essential. Good documentation can speed up the surveyor’s approval and reduce delays.
