Understand car insurance add-ons in simple words, what each cover does and who needs it, so you pick only what suits your car. Get a free quote today.

Car insurance add-ons are optional covers that you add to your main policy for extra protection. You do not need all of them. Pick the ones that match your car's age, your driving area and your budget.

A basic comprehensive policy covers many risks, but it leaves some gaps. Add-ons fill those gaps. Each one costs extra premium, so it helps to know what you are paying for.

What are add-ons in car insurance?

An add-on (also called a rider) is a small extra cover that you buy with your own-damage policy. It changes how a claim is paid in certain cases. For example, it can remove the depreciation cut on parts, or pay for a tow when your car breaks down.

Add-ons are usually sold with a comprehensive car insurance policy. A third-party policy only covers damage to others, so add-ons do not fit with it. Terms differ by insurer, so always check your policy wording.

Common car insurance add-ons

Here are the add-ons you will see most often:

  • Zero depreciation: The insurer does not cut depreciation on replaced parts like plastic, rubber, glass and metal, as per policy terms. Your claim pay-out is usually higher.
  • Engine protection: Covers engine damage from water entering the engine, or oil leakage after an accident.
  • Return to invoice: If your car is stolen or is a total loss, you may get back the invoice value instead of just the IDV.
  • Roadside assistance: Help with towing, flat tyre, dead battery or running out of fuel.
  • Consumables cover: Pays for small items like nuts, bolts, oil, coolant and screws used during repair.
  • Key and lock replacement: Helps if your car key is lost or stolen.
  • NCB protection: Lets you keep your No Claim Bonus even after one claim, usually with limits.
  • Daily allowance: Gives you some money each day while your car is in the garage.
  • Tyre protection: Covers tyre damage that a basic policy may not pay for.
  • Battery cover: For electric vehicles, this covers the battery pack, as per terms.

Which add-ons suit which driver?

Your need depends on how you use your car. Think about these points:

  • New car: Zero depreciation is often the first add-on to think about. It is usually offered for newer vehicles, often up to around 5 years old, but check insurer rules. Also look at return to invoice cover.
  • City driver: Heavy traffic means more small scrapes. Consumables cover and zero depreciation can help.
  • Rain or flood area: Engine protection is worth a look, because water damage to the engine is usually not paid without it.
  • Long highway trips: Roadside assistance gives peace of mind when you are far from home.
  • Older car: Many add-ons are not offered for older vehicles. Keep your cover simple and check what is available.

How to choose without overpaying

Do not buy add-ons only because they are offered. Follow these steps:

  1. List the risks you really face, like floods, theft or daily city traffic.
  2. Check your car's age and which add-ons your insurer allows for it.
  3. Read the limits. Some add-ons allow only a few claims per year.
  4. Compare the extra premium with the possible benefit.
  5. Keep only the add-ons that solve a real problem for you.

Things to check before you buy

Add-ons have rules. Look at these in your policy wording:

  • Claim limits: Many add-ons cover only a set number of claims in a policy year.
  • Age limits: The vehicle may need to be within a certain age.
  • Exclusions: Some damage is still not covered. For example, engine protection usually does not pay for normal wear and tear or mechanical breakdown.
  • Deductibles: You may still pay a part of the claim.
  • Cashless network: Ask whether the add-on works at network garages.

Also remember that an add-on does not save a claim from rejection if the basics are wrong. An expired policy, drunk driving or driving without a valid licence can still lead to rejection.

Can you add covers later?

Most add-ons are chosen when you buy or renew your car insurance. Some insurers may allow changes in the middle of the term, but this is not common. The easy time to add or drop covers is at renewal. Review your add-ons each year, because your needs change as your car gets older.

If you are buying a new car, talk through the add-on list before you finish the purchase. If you need help, you can get a quote and ask our team to explain each cover in plain words.

Insurance rules and add-on terms can change, and each insurer has its own conditions. Your policy document is the final word on what is covered.

FAQs

Are car insurance add-ons compulsory?

No. Only third-party cover is compulsory under the Motor Vehicles Act, 1988. Add-ons are optional and you choose them for extra protection.

Can I buy add-ons with a third-party policy?

Usually no. Add-ons work with the own-damage part of a comprehensive policy. A third-party policy does not cover your own car.

How many add-ons should I take?

There is no fixed number. Take only the ones that match your car's age, your area and your driving. Too many add-ons can raise your premium without real benefit.

Do add-ons cover every claim?

Not always. Many add-ons have limits on the number of claims and have exclusions. Check your policy wording before you buy.
