How to switch business insurance without a gap

To switch business insurance without a gap, buy and bind the new policy first, set its start date to the exact day the old policy ends, and only then cancel the old one in writing. The two places a switch usually goes wrong are claims-made coverage, where a new policy with a fresh retroactive date can quietly drop protection for your past work, and certificates, since every landlord and client holding your old certificate now holds proof of a policy that’s about to stop.

Switching at renewal is easiest, because the old policy just ends and nothing needs refunding. Switching mid-term works too, but it brings a cancellation refund that may not be the straight share of the premium you expect, and a final audit that can still send you a bill months later.

The order of operations

Here’s the sequence that keeps you covered from one policy to the next:

1. Pull your current policy and your contracts. Have the declarations pageDeclarations pageThe declarations page is the summary at the front of an insurance policy listing who’s insured, what’s covered, the limits, deductibles, premium and policy dates.Read the definition, the endorsements and any lease or client contract that sets insurance requirements in front of you, because the new policy has to meet the same requirements, endorsements included.
2. Request your loss runsLoss runA loss run is a report from your insurer listing the claims filed under your policies over a set period, with dates, amounts paid and whether each is still open.Read the definition. Most new insurers will ask for your claims history, and it can take time to arrive, so ask your current insurer for it early. What are loss runs? explains what’s on them.
3. Get the new quote for the same coverage. Compare limits, deductibles, endorsements and exclusions line by line, since a cheaper quote that drops an additional insured endorsement or a sublimit you relied on isn’t really the same coverage.
4. Bind the new policy. Get written confirmation, such as the policy itself or a insurance binderInsurance binderAn insurance binder is a temporary document confirming that coverage has started while the insurer finishes issuing the full policy.Read the definition, with the effective date on it.
5. Set the start date to match. Make the new policy’s start date the same day the old one ends or is cancelled, and check the time of day as well, because many policies start and end at a stated hour, such as 12:01 a.m.
6. Cancel the old policy in writing. Ask for written confirmation of the cancellation date and of any refund owed, and stop any automatic payments.
7. Send new certificates. Everyone who holds your old certificate needs a new one.

Mid-term refunds aren’t always pro rata

When you cancel partway through a policy periodPolicy periodThe policy period is the span of time between a policy’s start and end dates, usually 12 months, during which its coverage is in force.Read the definition, the insurer returns the unearned part of the premium, meaning the part that would have paid for the months you no longer need. How it calculates that part is the surprise.

A pro rata refund gives back exactly the unused share, so cancelling halfway through a one-year policy returns half the premium. A short rate refund gives back less than that, keeping an extra amount because the insurer’s costs of writing the policy were meant to be spread across the full term. Which method applies depends on the policy’s cancellation clause and on your state’s rules, and the rules really do differ. In New York, for example, the Department of Financial Services’ Office of General Counsel has said an insurer may calculate the return premium on a short-rate basis when the policyholder cancels mid-term, as long as that matches the insurer’s filed rates and rules, but that on a premium-financed policy unearned premium must be returned pro rata.

That’s one state’s answer, and yours may differ. What it means in practice is that the savings from switching mid-term can be smaller than the gap between the two premiums suggests, so ask your current insurer, in writing, how the refund will be calculated before you cancel. If the short-rate penalty eats most of the difference, waiting for renewal may be the cheaper move.

The claims-made trap

For general liability, which is usually an occurrence policyOccurrence policyAn occurrence policy covers injury or damage that happens during the policy period, even if the claim is filed after the policy has ended.Read the definition, a switch is close to a straight swap. For anything written on a claims-made basis, though, getting it wrong is the most expensive mistake on this page.

An occurrence policy covers incidents that happen while it’s in force, no matter when the claim arrives, so the old policy goes on covering what happened during its term even after you’ve left. A claims-made policyClaims-made policyA claims-made policy covers claims first made against you during the policy period, for work or incidents that happened on or after the policy’s retroactive date.Read the definition works the other way round. It covers claims first made while the policy is active, for work done on or after its retroactive dateRetroactive dateA retroactive date is the earliest date of work or events a claims-made policy covers, so anything that happened before it isn’t covered, even if the claim is new.Read the definition, and professional liability is usually written this way. Once the old claims-made policy ends, it stops responding to new claims, even about work it would have covered the day before.

So everything depends on the new policy’s retroactive date. If the new insurer agrees to keep your existing retroactive date, often called giving you prior acts coverage, the new policy picks up claims about past work where the old one left off, and there’s no gap. If the new policy starts a fresh retroactive date on its first day, every project you did before the switch falls outside it, while the old policy, now cancelled, won’t respond either, which leaves you in the worst possible spot: the work is still yours, the client can still make a claim about it, and neither policy may answer.

If the new insurer won’t keep your retroactive date, the fallback is an extended reporting periodExtended reporting periodAn extended reporting period (ERP) gives you extra time after a claims-made policy ends to report claims about work done while the policy was in force.Read the definition, often called tail coverage, bought from the old insurer, which gives you more time to report claims about work done while the old policy was in force. States set some of the rules around this. North Carolina’s published guidelines for claims-made policies, for one, require the policy to offer an extended reporting period on cancellation or nonrenewal, with a 30-day window after the cancellation date to elect it, and say an insurer can’t move an existing retroactive date forward without the policyholder’s written consent. Other states have their own rules, so ask both insurers about the retroactive date before you sign anything, and get the answer on the new policy’s declarations page. One more step belongs before the switch: report anything that could become a claim, like an unhappy client or a threatening email, to the old insurer in writing while its policy is still in force. The new application will ask about known problems, and something you knew about before the switch is commonly excluded from the new policy even when the retroactive date carries over. Occurrence vs. claims-made policies explains the difference in more depth.

Who still has your old certificate?

Fair question, and the answer is usually more people than you’d guess off the top of your head: your landlord, any general contractor you sub for, a property manager, a corporate client’s vendor team, an event organizer.

Each of them has a certificate of insuranceCertificate of insuranceA certificate of insurance (COI) is a one-page summary that proves your business has insurance, listing your policies, limits, insurers and policy dates.Read the definition showing a policy number and dates that are about to stop being true. Some of them track expiry dates and will ask for a new certificate on their own, but you’re better off sending it first, because a landlord or GC who notices the old policy has ended before they’ve seen the new one may treat it as a lapse.

The certificate is only proof of the policy behind it, though, so the endorsements have to carry over too. If your lease names the landlord as an additional insuredAdditional insuredAn additional insured is a person or company, such as a landlord or client, added to your liability policy so it can protect them from claims tied to your work.Read the definition, or a subcontract requires a waiver of subrogationWaiver of subrogationA waiver of subrogation is an agreement, usually added to your policy by endorsement, that stops your insurer from recovering claim payments from a specific client, landlord or contractor.Read the definition, the new policy needs those endorsements before the new certificate can show them. With Corgi, a certificate is available the day you buy, and you can download it or send it to a landlord or client from your account.

Your old insurer isn’t finished with you yet

Switching doesn’t end the old relationship cleanly, and it’s worth knowing what’s still open.

Claims stay where they began. A claim for an incident during the old policy’s term, or reported under an old claims-made policy, is handled by the old insurer under that policy’s terms, and it doesn’t move to the new insurer because you did. Keep your old policy documents, and keep your contact for the old insurer’s claims team.

The audit can still come. Policies priced on estimated payroll or sales, like workers’ comp and often general liability, are usually reconciled by a premium auditPremium auditA premium audit is the insurer’s review of your actual payroll, sales or other figures after a policy ends, used to replace estimates and set your final premium.Read the definition after the policy ends, and that includes a policy you cancelled mid-term. If your actual payroll ran higher than the estimate, the old insurer may send an additional bill months after you’ve left, so keep the payroll and sales records for that period ready. What is a premium audit? covers how to prepare.

Workers’ comp deserves one extra check. It’s set by state law, and if your state requires you to carry it, a gap of even a few days can matter, and if you’re switching it at the same time as everything else, confirm the new policy’s start date with the same care. The U.S. Department of Labor’s list of state workers’ compensation agencies points to your state’s agency if you want to confirm what applies.

Last, the timing of the whole switch. The NAIC suggests reviewing all your insurance policies annually and comparing the cost of equivalent coverage from several insurers, and the renewal date is the natural point to do it, since there’s no refund to calculate and no overlap to manage. If your renewal price is what started this, your business insurance renewal went up walks through what to ask before you move.
