All risks insurance is a comprehensive form of insurance coverage, typically offered as part of property-casualty insurance. It is one of the two most common types of insurance coverage for homeowners and business owners. All risks insurance generally allows policyholders to seek compensation for losses caused by any event that is not expressly excluded from the policy. It is thus important for policyholders to understand exactly what events are excluded from the coverage, so that they can select the most appropriate policy for their needs.

Unlike named perils insurance, all risks insurance does not limit the policyholder to seeking compensation for only those events specifically detailed in the policy. Instead, the policyholder is covered for almost any kind of loss, unless it is explicitly excluded. This is beneficial to policyholders, since it allows them to ensure that their investments are protected against a wide variety of potential risks. In addition, all risks insurance policies may give policyholders the opportunity to add coverage for certain events that have been ruled out by the policy, via a rider or floater.

All risks insurance essentially requires the insurer to provide compensation if "all risks" of potential loss, outside of those expressly excluded in the policy, actually result in the policyholder incurring a loss. This type of policy is particularly desirable for owners of high-value properties, since it provides wider coverage than named perils insurance. For example, a policy that has been tailored to cover all risks may include coverage for losses caused by fire, theft, or natural disasters, as well as losses due to accidents or vandalism.

All risks insurance provides comprehensive coverage for a variety of potential losses, making it a desirable choice for homeowners and business owners alike. For this reason, it is important for policyholders to carefully review their insurance policies to ensure that their investments are adequately protected by the specific coverage provided. In addition, it is important for policyholders to understand what events are excluded from the coverage and to add a rider or floater if they believe they need additional protection against certain events.
