Yes and no. Some comprehensive plans like those provided by AIG, Aviva, AXA (only SmartDrive Flexi plans), BudgetDirect, China Taiping, DirectAsia, Ergo, Etiqa, and many more, do cover water damage. While the majority of insurers offer flood damage coverage, some do not.
This means that the only way to know if you’ll be covered for flood damage is to ask your insurer directly, or read through your insurance policy in detail. For more information on car insurance policies, you can easily find out more with MoneySmart’s Car Insurance Wizard.
