Aon vs Chubb: How Do They Compare for Builders Risk Insurance?

Aon says its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines. For builders risk, this is evidence of Aon’s brokered market offering; the page does not identify the insurer for a buyer’s placement. ³Company-reported. Aon’s global construction and infrastructure practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement.

Chubb underwrites builders' risk insurance directly for commercial and residential contractors and for engineering construction such as bridges and tunnels. ⁷Company-reported. Builders' Risk Insurance product page.

The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. ³Not found in reviewed sources. Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement.

Aon describes its global construction and infrastructure practice as serving contractors, owners, developers, engineers, architects, designers, financiers and investors, and says it works with organizations of varied sizes and complexity. ³Company-reported. Audience described for Aon’s global construction and infrastructure practice. It does not establish U.S. state availability or underwriting eligibility for a placement.

Aon lists Builders Risk under construction property and says its construction property offering can address accidental damage to project property or materials during construction and operations. That is a broker’s description of the line, not a grant of coverage for a buyer. ³Company-reported. Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage.

Chubb offers Individual Project Builders Risk and Master Programs, difference-in-conditions coverage for selected construction projects, both physical-damage and delay-in-opening coverage, International Builders Risk for U.S. domestic clients, a portfolio of green endorsements, and contract-penalty coverage tied to a covered physical-damage loss. ⁷Company-reported. Coverage list; subject to the policy as issued.

The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. ³Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed.

Chubb says it offers capacity in a variety of positions, including primary, full limit, quota share, buffer and excess layer, but the reviewed page does not publish specific dollar limits. ⁷Not found in reviewed sources. Coverage list and Benefits section.

Aon describes project risk-advisory services to understand project-specific risks and develop risk-transfer, management or mitigation strategies.
