What to Do When a COI or Policy Expires During a Project
Maintain continuous proof of insurance when a project, lease, vendor relationship, or event spans a policy renewal date. Source-checked guidance for U.S. solo and small service businesses.
A certificate of insurance reflects the policy's information at the moment it was issued — it does not promise that the policy will renew on the same terms, or renew at all. Limits, carrier, endorsements, and dates can all change at the next renewal, which means a certificate issued last year should never simply be reused as proof that coverage is still current or unchanged.
A certificate is a snapshot, not a subscription
The certificate a client accepted at the start of a project describes the policy as it existed on the day it was issued. Nothing about that document commits the insurer to renewing on the same terms, at the same limits, with the same endorsements — or renewing at all. A long project that spans a renewal date needs fresh evidence at that renewal, not a reused copy of the original certificate.
A twelve-month contract, a January renewal
A janitorial vendor starts a twelve-month property-management contract in October, while the vendor's general-liability policy renews the following January. The client accepts the initial certificate at signing, then correctly requires a renewal certificate before the January date arrives. If any endorsements changed at that renewal — a different additional-insured wording, a different limit structure — the vendor needs to confirm the new forms too, not just forward a certificate showing a later expiration date.
"Automatic renewal" doesn't mean "identical terms"
Even when a policy renews without a gap in coverage, the terms attached to that renewal are not guaranteed to be identical to the expiring term. Limits, deductibles, and endorsements can all shift at renewal for reasons unrelated to the specific client relationship — a change in the insurer's underwriting appetite, a claims history update, or a broader program change.
Building a renewal calendar instead of reacting to expiration notices
For any client relationship that outlasts a single policy period, a simple tracking habit prevents the gap from becoming visible only when a client's procurement system flags it.
- The earliest expiration date across every required policy
- The contract's actual end date, compared against that expiration
- A reminder set well before expiration, not on the expiration date itself
- Confirmation that renewal endorsements match what the contract still requires

Frequently asked questions
Does a certificate of insurance guarantee the policy will renew on the same terms?
No. A certificate reflects the policy as it existed when issued. Limits, carrier, and endorsements can all change at the next renewal.
Is it enough to send a renewal certificate showing a later expiration date?
Not necessarily. If endorsements changed at renewal, the client's underlying requirement may no longer be satisfied even though the certificate shows continuous coverage on paper.
What is the risk of letting a certificate lapse while a contract is still active?
It can put the business out of compliance with the contract even if the underlying policy is actually still in force — many contracts specifically require continuous, current evidence to be on file.
