What the 2027 construction insurance outlook means for contractor COIs

WTW published its Insurance Marketplace Realities 2027 report for construction on October 1. The headline for anyone managing contractor COIs: most lines are steady, and the expensive one keeps getting more expensive.

The outlook by line

Umbrella has been the pressure point for years

This isn't new. Back in 2021, ENR reported that umbrella and excess renewals were costing contractors 50% to 100% more, as carriers raised prices, cut limits and raised attachment points. Rates have cooled since then, but umbrella keeps rising faster than the rest of the program.

Why that shows up in your contractor COIs

Project requirements rarely bend to the market. If the contract calls for a $10 million umbrella, it calls for $10 million whether the trade contractor's renewal went up 5% or 15%.

Put that next to a bidding market where, as Construction Dive reported from ABC's Anirban Basu, jobs that once drew 2 to 4 bids are drawing 12 to 16. Thin margins and rising umbrella costs push in the same direction: carry less, and hope nobody checks.

So check umbrella first. On every contractor COI, confirm the umbrella or excess limit meets the project requirement, that it follows form over the underlying policies the contract requires, and that it won't expire before the work is done.

The upside at your own renewal

WTW notes that carriers give favorable underwriting consideration to strong management of the trades a firm hires. A record showing every contractor checked against project requirements, with each gap tracked to a fix, is the kind of evidence an underwriter can use. A folder of unread certificates isn't.
