Additional insured

An Additional Insured is a person or organisation that is not initially a party to an insurance policy but is added at the request of the primary (or named) insured. This extension provides the additional party with certain rights and protection under the policy, usually in connection with specific business relationships, contracts, or projects.

This term is most commonly used in business liability insurance, particularly in contractual agreements, vendor relationships, client partnerships, or construction projects, where liability needs to be shared or extended temporarily or conditionally.


đŸ§Ÿ Example Scenario

Imagine a small business hires a contractor to carry out renovations at its office. The contractor might request to be listed as an additional insured on the business’s general liability insurance policy. This ensures they are covered if a third party suffers injury or damage due to the contractor’s work while on the premises.


🔍 Key Features of an Additional Insured

  • Third-Party Protection: Extends policy coverage to a party other than the original insured.
  • Named in Policy Endorsement: Usually formalised through an “Additional Insured Endorsement” or clause in the contract.
  • Conditional Coverage: The additional insured typically receives limited coverage, often related only to the scope of work or liability arising from the named insured’s operations.
  • Temporary or Permanent: The extension can be valid for the duration of a project or the entire policy term.

đŸ§© Why Add an Additional Insured?

  1. Contractual Requirement
    Many clients or vendors insist on being added to your insurance policy to protect themselves from liabilities arising out of your work.
  2. Risk Sharing
    In joint ventures or shared projects, both parties may want to be insured under one umbrella to avoid dispute over claim responsibilities.
  3. Legal Protection
    It minimises legal conflicts if something goes wrong—especially in construction, consultancy, or service-based industries.
  4. Strengthened Relationships
    Providing this extension builds trust and shows professionalism, especially when working with larger firms or public sector clients.

🛑 Limitations of Additional Insured Status

  • Not Full Coverage: Additional insureds don’t receive the same scope of protection as the named insured.
  • Coverage Applies to Specific Work: Protection is usually tied to the operations, service, or activity specified in the agreement.
  • No Ownership Rights: They generally cannot modify or cancel the policy.
  • Claim Settlement Hierarchy: In many cases, claims are first settled with the named insured’s liability, and only then involve the additional insured.

Always clarify who is covered, what is covered, and for how long before listing someone as an additional insured. Ambiguities can result in disputes or claim denials. Let your insurance broker review the contractual obligations to ensure the policy terms reflect your business intent.
