TradeGuardAdditional insured vs. additional interest
Additional interest is a notification status only: you're told if the policy changes or cancels, but you get no coverage. Additional insured extends actual liability coverage to you. Accepting “additional interest” thinking you're covered is a genuine, common trap.
Real coverage. You're an insured party on the policy for liability arising out of the named insured's work, and can tender a claim to their carrier.
Notification only. You're flagged as an interested party and told about cancellations or changes, but you have no right to coverage under the policy.
If a sub lists you as an additional interest, you are not covered. Only additional insured status (via endorsement) actually protects you.
Why this one bites
“Additional interest” shows up a lot in personal lines and rental/tenant contexts, and it can appear on paperwork that looks a lot like a certificate. Because the phrasing is so close to “additional insured,” busy people accept it as equivalent. It isn't. Additional interest carries zero coverage rights; it's a courtesy notification. If a claim hits and you assumed you were covered, that assumption fails exactly when it matters most.
How to avoid it
On every subcontractor certificate, confirm the wording says additional insured, backed by an endorsement, not additional interest. If you only see additional interest, the sub has not extended coverage to you, full stop. Send it back and require the proper endorsement.
When a subcontractor uploads a certificate, TradeGuard reads it and records whether you're listed as an additional insured, and the exact name shown. Set “require additional insured” on a trade, and any sub whose COI doesn't include it is flagged automatically, so a missing endorsement doesn't slip onto your site unnoticed.
TradeGuard tracks additional-insured status, the named party, and your endorsement notes in one place. It doesn't replace reading the actual endorsement form; always confirm the specific form and edition with your broker.
This is general information, not legal or insurance advice. Endorsement forms, editions, and coverage vary; confirm requirements with your broker and the terms of your subcontract.
FAQ
Does additional interest give me any coverage?+
No. It only means you'll be notified of certain policy changes or cancellation. It grants no right to coverage. For protection you need additional insured status.
Why do I sometimes see additional interest on a certificate?+
It's common in rental and personal-lines contexts and sometimes gets used loosely. Treat it as a red flag on a subcontractor COI and require additional insured instead.
Stop trusting the checkbox
TradeGuard reads every subcontractor's certificate, records whether you're listed as additional insured, and flags the ones that aren't, before they're on your job site.
