All Risks Insurance, also known as Open Perils Insurance, is a type of property insurance that generally covers accidental physical loss or damage unless the cause of the loss is specifically excluded in the policy. It provides broader protection than named perils insurance, but coverage is still subject to the policy’s terms, exclusions, limits, along with deductibles. 

With All Risks Insurance, a claim is generally covered unless the insurer identifies a policy exclusion that applies. Understanding what is covered and, more importantly, what is excluded can help you choose the right business insurance coverage for your assets. In this guide, we’ve explained how this insurance type works, its coverage, exclusions, benefits, cost factors, and how it compares with named perils insurance. 

What is All Risks Insurance?

All Risks Insurance is a type of property insurance, which sits inside the wider world of property and casualty insurance. It helps protect insured assets against accidental physical loss or damage. Rather than listing every covered peril, it specifies the perils that are excluded. This is the reason it’s known as open perils insurance. Furthermore, if a loss isn’t specifically excluded and the policy requirements are met, then it may be covered. However, the final decision always depends on the policy wording, exclusions, limits, as well as endorsements.

What makes an all-risks insurance policy different?

  • Broader coverage: Covers accidental physical losses unless they are specifically excluded.
  • Exclusion-based approach: Coverage depends on whether the cause of loss is excluded under the policy.
  • Flexible protection: Can cover commercial buildings, equipment, inventory, furniture, and other insured assets against many unexpected events.
  • Policy wording matters: Coverage and exclusions vary by insurer, so reviewing the policy carefully is essential.
Example: Suppose a warehouse experiences unexpected damage after a water pipe bursts suddenly. If the cause of loss isn’t excluded under the policy, all risks insurance may cover the damage, subject to the policy’s terms and conditions. Now, this broader approach is one of the main reasons why businesses choose it over named perils insurance. 

How Does All Risks Insurance Work?

An All Risks Insurance policy assesses every claim against the policy terms just to determine whether the loss qualifies for coverage. Here’s how it works:

  • Covered Property: The insurance initially confirms that damaged property is insured under the policy, like buildings, equipment, inventory, or even machinery. 
  • Cause of Loss: The actual cause of damage is carefully reviewed to determine whether the peril (cause of loss) is covered or even specifically excluded. 
  • Policy Limits: Coverage is subject to the policy limit, whichis the maximum amount the insurer will pay for a covered claim. You will findthese limits listed on your business insurance declarations page.
  • Deductibles: The deductible is the amount that the policyholder pays before insurance covers the remaining eligible loss. 
  • Exclusions and Conditions: Exclusions in the policy, conditions, along with endorsements, determine when coverage applies and when it doesn’t.
  • Claims Process: Now, the insurer reviews the damage, supporting documents, and policy terms before approving or denying the claim.

What Does All Risks Insurance Cover?

One of the biggest advantages of all risks insurance is that it’s not just limited to a predetermined list of covered events. Instead, it generally responds to accidental loss or damage unless the peril (cause of loss) is specifically excluded. Depending on the policy, coverage may include: 

  • Fire and Smoke Damage:  It covers physical damage that resulted from fire, smoke, and firefighting efforts, subject to the policy terms. 
  • Theft: The insurance may cover the loss or damage of insured property of the business resulting from theft or attempted theft. 
  • Vandalism: Helps protect against intentional damage to covered property, including buildings, equipment, and business assets as well. 
  • Windstorms and Certain Weather Events: May cover damage due to windstorms and other covered weather-related events, unless specifically excluded. 
  • Accidental Physical Damage: Covers sudden and even unforeseen physical damage to insured property caused by unexpected incidents.
  • Other Covered Causes of Loss: Any accidental physical loss that isn't specifically excluded under the policy may also be covered, provided all policy conditions are met.
Important: Coverage varies by insurer and their policies. So, always review the policy wording, exclusions, endorsements, and coverage limits as well in order to understand what is and isn’t covered. 

Potentially Covered vs. Commonly Excluded

You can compare the losses that may be covered with those that are commonly excluded. It’s one of the most effective ways to understand all risks insurance coverage. Although all-risks insurance usually provides broader protection than named-perils policies, every policy contains exclusions that define its actual scope of coverage. 

Potentially Covered Losses Commonly Excluded Losses
Fire and smoke damage Normal wear and tear
Theft or attempted theft Gradual deterioration
Vandalism and malicious damage Intentional damage
Windstorms and certain weather events Floods (unless separately covered)
Accidental physical damage Earthquakes (unless separately covered)
Damage to insured buildings, equipment, machinery, furniture, and inventory War, terrorism, or nuclear-related risks (subject to policy wording)
Other accidental physical losses not specifically excluded Certain cyber-related losses and other policy-specific exclusions
Disclaimer: This table is just for general informational purposes. Coverage exclusions vary by insurer, policy type, endorsements, along with applicable state regulations. Always review your policy wording carefully to determine the exact protection provided. 

What is Typically Excluded From All Risks Insurance?

Actually, one of the biggest misconceptions about all risks insurance is that it covers every possible loss. But in reality, the policy is exactly defined as much by its exclusions as by its coverage. These exclusions help insurers differentiate between sudden, accidental events and losses that develop over time. The following are commonly found in many all-risks insurance policies: 

  • Wear and Tear:  This insurance type is designed for unexpected events, not just the natural aging of buildings, machinery, equipment, or even other insured property. Routine maintenance and repair-related works still remain the owner’s responsibility. 
  • Gradual Deterioration: Damages due to rust, corrosion, mold, rot, or sometimes long-term deterioration is generally excluded in this policy. This is because it develops over time rather than a sudden accidental event. 
  • Intentional Damage: Losses caused deliberately by the policyholder, employees, or even through fraudulent acts are typically not covered. 
  • War and Nuclear Risks: All damage arising from war, military action, nuclear hazards, or radioactive contamination is commonly excluded due to the catastrophic nature of these events. 
  • Flood and Earthquake: Although all risks insurance gives broader protection, flood and earthquake damage is usually excluded under standard policies and may need separate coverage or endorsements. If your property sits in a high-water area, look at how flood insurance for businesses works before storm season.
  • Certain Cyber-Related Losses: Financial losses from cyber attacks, ransomware, data breaches or other digital threats are generally covered under cyber insurance rather than property insurance. It is worth knowing the difference between cyber liability and commercial insurance before you assume you are protected.
  • Other Policy-Specific Exclusions: Every insurer defines additional exclusions that depend on the policy type, industry, and risk profile. And these may apply to specific property, business activities, or specific cause of loss. 
Insurance Insight: Experienced risk advisors don’t assess an all-risk insurance policy by asking only. “What does it exactly cover?” They ask as well. “What could prevent a claim from being paid?” Reviewing exclusions, endorsements, and policy conditions before a loss occurs can help businesses identify coverage gaps and determine whether additional protection is required for risks like flood, earthquake, or incidents. 

Key Benefits of All Risks Insurance

All risks insurance is much more than a blanket cover. During unforeseen events, it assists businesses in protecting their commercial property, minimising financial losses, and enhancing their overall risk management strategy.

  • Broader Protection for Insured Property: This is the typical coverage policy that provides protection for commercial buildings, equipment, machinery, inventory, and other physical property unless there is a cause of loss exclusion.
  • No Named Perils: Protection is not limited to only named risks, like with named perils coverage. Under certain terms and conditions of the property insurance policy, this can benefit businesses in avoiding any unforeseen lack of coverage.
  • Tailored Coverage: Limits, deductibles, and endorsements can be customized to suit your business operations, industry risk, and property values.
  • Minimized Financial Disruption: Unexpected property damage can cause disruption to operations and recovery costs. An appropriate policy can allow businesses to recover quicker while at the same time preserving valuable assets.
  • Helps with Better Risk Management: Knowing what is covered, what is not covered, and where further cover might be necessary enables businesses to make better insurance decisions.

All Risks Insurance vs. Named Perils Insurance

Both all risks insurance and named perils insurance protect commercial property, but they differ in how they determine covered causes of loss. Understanding these differences can help businesses choose coverage that matches their assets, operations, and risk exposure.

Insurance Comparison Table
Feature All Risks (Open Perils) Insurance Named Perils Insurance
Coverage Basis Covers accidental physical loss unless the cause of loss is specifically excluded. Covers only the causes of loss specifically listed in the policy.
Coverage Scope Generally provides broader protection for insured property. Limited to the named perils identified in the policy.
Claim Evaluation The insurer determines whether an exclusion applies to the loss. The insurer verifies whether the cause of loss is listed as a covered peril.
Coverage Gaps May reduce unexpected coverage gaps, subject to policy exclusions. Unlisted causes of loss are generally not covered.
Best Suited For Businesses with valuable commercial buildings, equipment, machinery, or inventory seeking broader protection. Businesses with well-defined risks or those looking for coverage against specific perils.
Key Consideration Review exclusions, endorsements, and policy conditions carefully. Review the list of covered perils to ensure your primary risks are included.

Who May Need All Risks Insurance?

All Risks Insurance is particularly beneficial for enterprises and people who have assets that are susceptible to various threats. In addition to coverage for listed events, it offers greater cover for unforeseen events to minimise financial disruption. May be appropriate for:

  • Business Owners: Cover a variety of unforeseen damage to offices, equipment, furniture, and other business property.
  • Commercial Property Owners: Protect buildings and facilities from unexpected events that may result in expensive repairs.
  • Contractors: Insure project equipment, tools, and other assets that are susceptible to damage or loss during the course of the project.
  • Construction Companies: Secure valuable equipment, materials, and multiple hazards in the construction site.
  • Businesses with Valuable Equipment: Make sure critical machinery, technology and operational assets can be protected to a greater extent.
  • Businesses with Inventory or Physical Assets: Minimize financial losses from damage or loss of inventory, supplies, and other valuables.

How Much Does All Risks Insurance Cost?

The cost of All Risks Insurance in the U.S. can vary from one business to another. It mainly depends on the value of the property or equipment you want to insure, where your business is located, the amount of coverage you choose, your deductible, and your claims history.

For many small businesses, the cost can range from around $300 to $1,500 per year. Businesses with expensive equipment, higher coverage needs, or greater exposure to risks such as theft, property damage, or natural disasters may pay more.

Some of the main factors that affect the cost include:

  • Property Value: The higher the value of the property or assets, the more coverage will likely be needed. Higher coverage limits may lead to higher premiums.
  • Insurance Premium: There may be a difference in insurance premiums among businesses based on their risk of operating.
  • Property Location: Areas that are subject to natural disasters, theft or other hazards may impact pricing.
  • Coverage Limits: Coverage limits are higher; the more coverage you receive, but at a higher the cost.
  • Deductibles: A higher deductible will reduce the premium; a lower deductible will raise the premium.
  • Frequent Claims: If a history of frequent claims, this could result in higher premiums because of risk perception.
  • Risk Exposure: This can be affected by the nature of the operations, safety measures, value of equipment, and potential hazards.

How to Choose the Right Coverage?

Your All Risks Insurance should be customised according to your assets, risks, and financial requirements of your business. Carefully checking coverage details can prevent unnecessary gaps in coverage and provide improved protection in the event of an unexpected loss.

  • Assess Business Risks: Determine risk factors that could affect operations, including property damage, theft, equipment failures, and others.
  • Identify Valuable Assets: Identify assets that need to be safeguarded, such as buildings, machinery, inventory, equipment, and technology.
  • Review Coverage Limits: Make sure that policy limits are adequate to repair/replace in case of a loss.
  • Understand Deductibles: Choose a deductible that fits your budget, but allows you to afford the claims you make.
  • Identify Coverage Gaps: Match the risks to the terms of the policy to identify areas that need extra coverage.
  • Get advice from an Insurance Professional: An insurance specialist can review your risks and tailor coverage to your operations. Before you commit, run through these questions to ask before choosing a commercial insurance broker.

Common Misconceptions About All Risks Insurance

Many people believe that when they buy a wide coverage policy, they are getting full coverage, but each policy has terms and conditions, limitations, and exclusions. Knowing how this type of coverage operates can assist companies in making smart insurance selections:

  • “Everything is automatically covered”-: This type of cover will guard against numerous risks, but only those included in the conditions of the policy.
  • “There are no exclusions”- All insurance policies come with exclusions. Some damages, events or conditions might require additional coverage or endorsements.
  • “Every all risks policy provides identical coverage”- That coverage may vary depending on the insurance company, the specific language in the policy, policy limits, deductibles, other coverage provisions, and more.
  • “Natural disasters are always covered”- Additional extensions or protection may be required for some natural events, or they may not be included.
  • “Additional insurance or endorsements are never required”- Some businesses require additional coverage to safeguard special equipment, valuable items or unusual business risks.

Conclusion

Business continuity is essential when dealing with unexpected events and it's more than just basic coverage. By knowing the key details of policies, exclusions, deductibles and coverage options, you can make sure your valuable assets are protected at the correct level.
