Key Differences in Umbrella and Excess Liability Insurance

Existing Coverage or a Designed Program

biBerk describes umbrella as an additional layer after a covered claim exceeds an existing liability limit, and requires an underlying policy. Chubb directly underwrites umbrella and excess casualty, with separate options for mid-sized and large companies and for energy and construction. A smaller business can ask whether Chubb’s Total Account Solution fits; a larger or specialized account can discuss a segment-specific structure. 3 7

How the Quote Moves

biBerk offers online or phone quote access. Chubb describes a broker platform, Express Umbrella, for reserving, quoting, binding, and issuing business, as well as agent or broker placement. That route may matter if your broker is building or servicing a specialized book; ask which application channel applies to your account. 3 7

Confirm the Layer in Dollars

Neither reviewed page gives universal limits or attachment points: biBerk explains the excess trigger, while Chubb says structure varies by account and program. Ask each quote to show the attachment point, limit, and underlying policies together so you can compare the actual layer. 3 7

What to Confirm in Umbrella and Excess Liability Insurance Quotes

  • Ask Chubb whether your business is being quoted through its small-business bundle or a segment program, and request the specific limit. 7
  • Ask biBerk to list the scheduled policy and whether auto liability is among its underlying coverages. 3
