Why Certificates of Insurance Are Critical When Hiring Subcontractors

Hiring subcontractors is common for many businesses, especially in industries like construction, landscaping, trucking, and specialized trades. However, one of the most important steps businesses often overlook is collecting a Certificate of Insurance (COI) from every subcontractor they hire.

Failing to obtain proper insurance documentation can expose a business to unexpected liability and higher insurance premiums.

What Is a Certificate of Insurance?

A Certificate of Insurance is a document issued by an insurance company or agent that verifies a business has active insurance coverage.

The certificate summarizes key policy information, including:

• Insurance carrier

• Policy number

• Coverage types

• Policy limits

• Policy effective dates

It serves as proof that the subcontractor has insurance protection in place.

Why Businesses Should Always Request a COI

Requesting a Certificate of Insurance before work begins helps protect your business in several ways.

1. Reduces Liability Exposure

If a subcontractor causes property damage or bodily injury while working on a project, their general liability policy may respond first.

Without proof of coverage, your business could become the primary target of a claim.

2. Protects Against Workers’ Compensation Charges

During workers’ compensation audits, payments to uninsured subcontractors may be treated as payroll for your company.

This means your insurance carrier could charge additional premium for those payments.

Obtaining proof of workers’ compensation coverage from subcontractors helps avoid these audit charges.

3. Demonstrates Professional Risk Management

Insurance companies often look favorably on businesses that consistently require subcontractors to provide certificates of insurance.

It shows that the company has structured risk management procedures in place.

What Coverage Subcontractors Should Carry

While coverage requirements vary by industry, subcontractors are often expected to carry at least the following:

General Liability Insurance

Protects against property damage and bodily injury claims.

Workers’ Compensation Insurance

Covers injuries sustained by employees while working.

Commercial Auto Insurance

Required if vehicles are used for business operations.

In some cases, businesses may also require subcontractors to carry umbrella liability coverage.

What to Look For on a Certificate of Insurance

When reviewing a COI, business owners should verify several important details.

Check that:

• The policy is currently active

• Coverage limits meet project requirements

• The named insured matches the subcontractor’s business name

• Policy expiration dates extend through the project timeline

Maintaining copies of certificates in your records is also important for future insurance audits.

Final Thoughts

Certificates of Insurance are one of the simplest and most effective ways businesses can protect themselves when hiring subcontractors.

By verifying coverage before work begins, business owners can reduce liability risks, avoid workers’ compensation audit surprises, and demonstrate strong risk management practices.
