Expired COI Premium Increase Calculator
When a sub's coverage lapses and a claim hits your policy, you pay the claim AND your premiums go up for years. See how much you're really exposed.
The "they said they have insurance" problem
Your sub tells you they're covered. Maybe they were—six months ago. But policies lapse, get cancelled, or never covered the work they're doing for you in the first place.
When the sub isn't covered
- Worker gets hurt on your job? You're paying the workers comp claim.
- Sub damages the customer's property? Your GL policy takes the hit.
- Sub's truck hits someone? You're named in the lawsuit.
- Your premiums go up—even if the claim wasn't your fault.
How common is this?
- 34% of contractors have at least one sub with lapsed coverage
- $47K average uninsured claim that hits the GC
- 72% don't verify coverage before each job
- 15% of COIs presented are outdated or falsified
Your annual audit will find this
Every year, your WC and GL carriers audit your records. They'll ask for COIs from every sub you used. If you can't prove a sub was covered when they worked for you:
- Their payroll gets added to YOUR premium calculation
- You'll owe back-premiums for the entire policy period
- Future premiums increase based on higher payroll exposure

ContractorHUB tracks sub COIs and alerts you when coverage needs verification.
Three coverages you need to verify
Each type protects you from different claims. Missing any one leaves you exposed.
General Liability
Covers property damage and bodily injury to third parties.
Without it: Customer's property damage = your claim
Verify: You're listed as additional insured
Workers Compensation
Covers employee injuries on the job site.
Without it: Sub's employee injury = your WC claim
Verify: Covers all workers on your jobs
Commercial Auto
Covers vehicles used for work purposes.
Without it: Vehicle accident = you're in the lawsuit
Verify: Hired & non-owned if using personal vehicles
How to protect yourself
Require COIs upfront
No certificate, no work. Make it policy before any sub steps on your job site.
Call to verify
COIs can be cancelled the day after they're issued. Call the carrier to confirm active coverage.
Get added as insured
Being listed as additional insured on their GL policy gives you direct protection.
Re-verify regularly
Policies expire. Set reminders to request updated certificates before renewal dates.
