Sure, when it comes to private car insurance, there are several add-on covers available that you can consider adding to your policy for enhanced coverage. Keep in mind that the availability of these add-ons may vary depending on your insurance provider and the specific policy you choose. Here are some common add-on covers available with a comprehensive (1st party) car insurance policy:

Zero Depreciation Cover: This cover ensures that you receive the full claim amount for the replacement of parts without any deduction for depreciation. It's particularly useful for newer cars.

Engine Protection Cover: It provides coverage for damages to the engine of your car due to water ingression, lubricating oil leakage, or any other internal damages not covered under standard insurance.

NCB Protection Cover: No Claim Bonus (NCB) is a discount given on the premium for every claim-free year. With NCB protection, you can retain your NCB discount even after making a claim during the policy period.

Return to Invoice (RTI) Cover: In case of theft or total loss of your vehicle, this cover ensures that you receive the original invoice value of your car including registration charges and road tax.
