When switching, you need to have all new certificates of insurance issued with the new carrier and sent out. It’s important to make sure that’s done in a timely fashion.

There is a common assumption that switching commercial carriers means your existing certificates of insurance just continue working until they expire. That is not how certificates work. A certificate of insurance is a snapshot of coverage on a specific date with a specific carrier and policy number. The moment your old policy cancels, every certificate referencing that policy becomes inaccurate. The vendors, landlords, and general contractors holding those certificates are relying on outdated information, and that creates real exposure on both sides if a claim happens during the gap.

What a certificate of insurance actually represents

A certificate of insurance is a one-page document showing the policy number, carrier name, coverage limits, effective and expiration dates, and any additional insured parties or special endorsements. It is not the insurance policy itself, and it does not grant coverage. It is evidence that coverage exists as of the date the certificate was issued. When the underlying policy changes — different carrier, different policy number, different limits, or different effective date — the certificate has to be reissued. We get into how this fits into the broader switching process in our guide on switching without disrupting operations.

Who needs new certificates after a carrier change

Every party that holds a current certificate needs a new one issued from the new carrier. That typically includes:

• Landlords and property managers on leased space
• General contractors who require subcontractor proof of insurance
• Customers and clients with contractual insurance requirements
• Vendors and suppliers with reciprocal coverage agreements
• Municipalities, ports, and licensing bodies for permitted work
• Lenders and equipment lessors that require listed loss-payee status

The reissue process and timing

The reissue process is administrative, but it has a sequence that matters. Here is how we handle it on every commercial transition:

1. Pull the list of current certificate holders from the outgoing agent or directly from your records.
2. Confirm any special endorsements, waivers of subrogation, or primary-and-noncontributory language that needs to carry over.
3. Bind the new policies with effective dates that match the old cancellation dates.
4. Issue the new certificates from the new carrier with matching effective dates and required endorsements.
5. Deliver the new certificates to every holder before the old policy cancels.

The timing piece is what trips up most transitions. Certificates that arrive a week late mean a week where a landlord or general contractor cannot prove you are insured on their job site or in their building. We make this part of the binding sequence, not an afterthought. Our walkthrough on whether new certificates are needed after changing carriers covers the timing in more detail.

What changes on the new certificate

Most of the certificate looks the same. The carrier name and policy number change, the effective and expiration dates change, and any policy form differences may show up in the descriptions section. Coverage limits should match what you had before unless you intentionally increased or decreased them during the switch. Additional insured language has to be replicated exactly, including any blanket additional insured endorsements that named all parties required by written contract. If a landlord previously required primary-and-noncontributory wording, that has to be confirmed on the new policy and reflected on the new certificate. None of this is hard, but all of it has to be checked.
