Hiring subcontractors can help your business take on more work, meet deadlines, and bring in specialized skills. But before a subcontractor steps onto a jobsite or begins work for a client, it is important to understand how their insurance may affect your business.
A subcontractor’s mistake, injury, or property damage can sometimes lead to a claim involving your company. That is why you should review subcontractor insurance requirements before work begins—not after something goes wrong.
Here is what small business owners should verify and why it matters.
Why Subcontractor Insurance Matters
Working with an independent contractor does not automatically remove your responsibility when something happens on a job.
Depending on the circumstances, your business could be named in a liability claim involving bodily injury, property damage, defective work, or another loss connected to a subcontractor.
Workers’ compensation questions can also arise. Simply calling someone an independent contractor does not always determine how state law or your insurance policy treats that worker.
Clear insurance requirements can help establish expectations before work begins and reduce surprises later.
1. Request a Certificate of Insurance
A certificate of insurance, often called a COI, summarizes the subcontractor’s active insurance policies.
It may show important information such as:
- General liability insurance
- Workers’ compensation insurance
- Commercial auto insurance
- Policy effective and expiration dates
- Insurance carriers
- Coverage limits
A COI is a useful starting point, but it should not be treated as proof that you’ve met every contract requirement.
For example, a certificate may list your company as an additional insured without confirming the exact policy endorsement that provides that protection.
That is why reviewing the details matters.
2. Verify General Liability Coverage
Most businesses that hire subcontractors should review the subcontractor’s commercial general liability insurance.
General liability coverage may respond when a subcontractor causes bodily injury or property damage during covered business operations.
Review the subcontractor’s liability limits and compare them with your contract requirements.
Depending on the work involved, you may want to verify:
- Each-occurrence limits
- General aggregate limits
- Products-completed operations coverage
- Property damage coverage
- Contractual liability provisions
The appropriate insurance limits can vary significantly based on the subcontractor’s work, project size, location, and potential exposure.
A roofing contractor, electrician, landscaper, consultant, and delivery company may each present very different insurance needs.
3. Confirm Additional Insured Status
Your contract may require the subcontractor to add your business as an additional insured on its liability policy.
Additional insured status may provide your business with certain liability protection under the subcontractor’s policy when a claim is connected to the subcontractor’s work.
But the wording matters.
Being listed on a certificate of insurance is not necessarily the same as being properly added to the policy. An insurance endorsement is generally what changes the actual policy terms.
Ask whether an additional insured endorsement is required and confirm that the endorsement matches the contract.
4. Review Workers’ Compensation Insurance
Small businesses should pay close attention to workers’ compensation when hiring subcontractors.
Requirements differ by state, business structure, number of employees, and type of work. In some situations, an uninsured subcontractor or their workers could increase the hiring business’s exposure.
Your insurance carrier may also consider uninsured subcontractors during a workers’ compensation audit.
Before work begins, verify whether the subcontractor carries workers’ compensation insurance when required.
Do not rely only on the subcontractor saying that their workers are independent contractors. Worker classification can involve state law, employment rules, and specific facts about how the work is performed.
5. Check Commercial Auto Insurance When Vehicles Are Involved
If subcontractors drive vehicles as part of the work, you may also need to review commercial auto insurance.
This can be especially important when subcontractors:
- Deliver materials
- Haul equipment
- Travel between jobsites
- Transport goods
- Operate vehicles on behalf of your company
Personal auto insurance may not provide adequate coverage for certain business activities.
Your subcontractor agreement may require specific commercial auto liability limits based on the work being performed.
6. Consider Professional Liability Coverage
General liability insurance does not cover every type of professional mistake.
If a subcontractor provides advice, designs, consulting, technical services, engineering, technology services, or another professional service, professional liability insurance may be important.
Professional liability coverage—sometimes called errors and omissions insurance—can help address certain claims involving professional mistakes, negligence, or failure to provide services as expected.
Businesses that use professional subcontractors should consider whether this coverage belongs in their subcontractor insurance requirements.
7. Make Sure the Policy Dates Cover the Work
Insurance limits matter, but so do policy dates.
Check the effective and expiration dates shown on the certificate of insurance.
If the subcontractor’s insurance expires while a project is underway, request an updated certificate before allowing work to continue.
For longer projects, create a process to track expiring subcontractor insurance certificates rather than reviewing documents only when a contractor is first hired.
8. Review Required Insurance Endorsements
Your subcontractor agreement may require more than basic insurance coverage.
Depending on the contract and type of work, requirements could include:
- Additional insured endorsements
- Primary and noncontributory wording
- Waiver of subrogation
- Products-completed operations coverage
These terms can affect how insurance responds when more than one company or insurance policy is involved in a claim.
They can also be easy to misunderstand.
If your business contract requires specific endorsements, review them with your insurance agent and legal advisor so you understand what they are intended to accomplish.
9. Keep Documentation Organized
Insurance verification works best when it is part of a consistent subcontractor management process.
Keep copies of relevant documents, including:
- Certificates of insurance
- Required endorsements
- Subcontractor agreements
- Policy renewal certificates
- Documentation of updated coverage
You may also want one person or team to check whether insurance documents meet your company’s requirements before approving subcontractors to begin work.
A simple process can make subcontractor risk management much easier as your business grows.
Insurance Requirements Should Match the Work
No single set of subcontractor insurance requirements fits every small business.
A contractor performing structural work may create very different risks from a marketing consultant working remotely. The right coverage requirements depend on the work being done, the contract, your industry, your location, and your own business insurance coverage.
That is why it helps to review your requirements before you hand them to subcontractors.
Your insurance agent can help you compare your business insurance policy with the types of subcontracted work you use and identify questions worth discussing with your legal advisor.
Review Requirements Before the Work Starts
Subcontractors can be an important part of your business, but you should address insurance before a project begins.
Start with the certificate of insurance, then look deeper. Verify coverage limits, policy dates, workers’ compensation requirements, additional insured status, and any endorsements required by your contract.
Clear requirements now can make it much easier to understand where coverage may apply later.
