Sooner or later, a client, general contractor, or property manager will say: “Send me your COI before you start.” A certificate of insurance is one of the most requested documents in contracting, and not having it ready can cost you the job. But many contractors do not fully understand what a COI is, what it proves, or how to get one quickly. Here is a plain-English guide to the certificate of insurance for contractors.
Key takeaways
- A COI is a one-page document proving you carry the insurance you say you do.
- Clients require it before you work, to confirm you are covered and to protect themselves.
- It summarizes your policies, limits, and dates, but it is not the policy itself.
- Your agent can issue a COI quickly, often same day, once your coverage is in place.
What a certificate of insurance is
A certificate of insurance (COI) is a standardized, usually one-page summary of your business insurance. It lists the types of coverage you carry (like general liability and workers’ compensation), your policy limits, your insurer, and the policy effective and expiration dates. Think of it as a snapshot that proves, at a glance, that your coverage is real and current. The most common format is the ACORD certificate, which nearly everyone in the industry recognizes.
Why clients require it
When a general contractor or property owner hires you, they are taking on some risk by letting you work on their project. Requiring your COI is how they verify you are actually insured before you start, so that if something goes wrong, your coverage, not theirs, responds. It protects them, and it signals that you run a legitimate, professional operation. In practice, no COI usually means no job, especially on commercial and larger residential work.
What is on a COI
A certificate of insurance typically shows:
- Your business as the insured, and your insurer.
- Types of coverage you carry, such as general liability, workers’ compensation, commercial auto, and umbrella.
- Policy limits for each coverage.
- Effective and expiration dates so the viewer knows the coverage is current.
- The certificate holder — the client or party requesting proof.
- Additional insured status, if the client is named as an additional insured (often requested alongside the COI).
Important: the COI summarizes your coverage, but it is not the insurance policy and does not change what the policy actually covers.
COI and “additional insured” go together
Clients frequently ask for two things in the same breath: a certificate of insurance, and to be named as an “additional insured” on your policy. These are related but different. The COI proves your coverage; being named additional insured actually extends certain protections of your policy to that client. If a contract asks for both, your agent handles both. (We cover additional insured in depth in a companion post.)
How to get a COI (and get it fast)
Getting a certificate is simple once your coverage is in place: you ask your insurance agent, tell them who the certificate holder is (and whether they need to be added as additional insured), and your agent issues it, often the same day. The key is to not wait until the morning a job starts. Smart contractors keep their coverage current and have a responsive agent who can turn around a COI quickly, because the request almost always comes with a deadline attached.
Common COI mistakes to avoid
A few things trip contractors up:
- Letting coverage lapse: an expired policy means you cannot produce a valid COI, and you lose the job.
- Not carrying what the contract requires: if the contract requires limits or coverages you do not have, your COI will not satisfy it.
- Waiting until the last minute: requests come with deadlines; a slow response can cost you the work.
- Confusing the COI with the policy: the certificate is proof, not coverage. Make sure the underlying policy is right.
Frequently asked questions
What is a certificate of insurance?
It is a standardized one-page document that proves your business carries insurance. It lists your coverages, limits, insurer, and policy dates. It is a summary and proof of coverage, not the policy itself.
Why do contractors need a certificate of insurance?
Clients, general contractors, and property owners require it to verify you are insured before you start work, so your coverage responds if something goes wrong. Without a current COI, you usually cannot be hired for a job.
How do I get a certificate of insurance?
Ask your insurance agent, tell them who the certificate holder is and whether they need to be added as an additional insured, and they will issue it, often the same day, as long as your coverage is active.
Is a certificate of insurance the same as the policy?
No. The COI summarizes and proves your coverage, but it is not the insurance policy and does not change what your policy actually covers. The underlying policy controls what is covered.
