What Are the Key Differences Between AIG and Heffernan Insurance Brokers General Liability Insurance?

Brokerage and On-Demand Distribution

Heffernan places general liability through its standard commercial brokerage and separately distributes an on-demand product with Thimble that buyers purchase online. AIG's evidence lists GL within selected programs with program administrators. These routes serve different buying contexts: standard commercial placements allow broker shopping, while the Thimble arrangement is a distinct online product. Ask which Heffernan route applies before comparing forms. [1] [4]

Limits, Insurer and Service

Heffernan says the Thimble product offers $1 million or $2 million limits and names Markel Insurance Company among the underwriters, while its standard brokerage pages publish no limits. AIG's overview also lacks account-specific limits. Buyers should compare the exact issuer, policy period and certificate details in the quote rather than carry figures from one channel to another.
