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

A Named Industry Focus vs. Two Distribution Paths

Relm says general liability is often required by leases and by enterprise or government contracts. It highlights companies in high-growth, high-risk or heavily regulated fields such as cannabis, biotech, psychedelic therapeutics, aerospace and defense, and technology. ⁴Company-reported. Casualty page framing; not a guarantee of eligibility for a particular company.

Heffernan doesn't organize around a named industry the way Relm does; it splits general liability into a standard commercial brokerage placement across many industries and a separate Thimble-partnered on-demand product instead. ¹ ³

Distribution Through Brokers on Both Sides

Relm distributes general liability through insurance brokers rather than a direct online quote, describing itself as a line-of-business option brokers can place for clients. ⁴ Heffernan's standard brokerage works similarly, shopping insurers on the client's behalf, while its separate Thimble-partnered product is bought directly online instead of through that broker relationship. ¹

A Named Insurer on One Side

Relm's page does not name a specific issuing insurer for general liability placements. ⁴ Heffernan's standard brokerage also names none, but its Thimble-partnered on-demand product is specifically underwritten by Markel Insurance Company. ³

Coverage and What Falls Outside It

Relm's page lists what casualty coverage generally excludes: employee injuries, professional errors, intentional or criminal acts, and damages from illegal activity. ⁴ Heffernan's reviewed pages describe coverage in broader terms instead, bodily injury and property damage caused by the company, without a comparable exclusions list on either of its two paths. ²

What Should You Confirm in Heffernan Insurance Brokers and Relm Insurance General Liability Insurance Quotes?

Ask Relm's broker which insurers write coverage for your specific industry, since none is named on its page. ⁴
Ask Heffernan whether you're being quoted through its standard brokerage or its Thimble-partnered on-demand product. ³
Confirm which insurer would issue your policy on Heffernan's standard brokerage path, since that one names none. ¹
Ask Relm's broker which of the listed casualty exclusions apply to your policy specifically. ⁴
