# Heffernan Insurance Brokers vs Relm Insurance General Liability Insurance

Relm markets general liability toward high-growth, heavily regulated industries like cannabis and aerospace; Heffernan names an insurer only on its separate on-demand product.

## Research Scope and Use

Use this comparison to evaluate Heffernan Insurance Brokers and Relm Insurance for General Liability Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Relm markets general liability to companies in high-growth or heavily regulated fields such as cannabis, biotech and aerospace, distributing the line through insurance brokers without naming an insurer. Heffernan's standard brokerage also names no insurer, but its Thimble-partnered on-demand product is underwritten by Markel Insurance Company.

## What Is General Liability Insurance?

General liability covers claims that your business injured someone, damaged their property or committed a specified personal or advertising offense. It does not insure your own building or equipment. [9](https://www.iii.org/article/commercial-general-liability-insurance "Commercial general liability insurance") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide")

## Key Differences in 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. [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance") (Evidence: Company-reported; scope: 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. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [5](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability")

### 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. [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance") 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. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")

### A Named Insurer on One Side

Relm's page does not name a specific issuing insurer for general liability placements. [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance") Heffernan's standard brokerage also names none, but its Thimble-partnered on-demand product is specifically underwritten by Markel Insurance Company. [5](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability")

### 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. [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance") 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. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

## What to Confirm in General Liability Insurance Quotes

- Ask Relm's broker which insurers write coverage for your specific industry, since none is named on its page. [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance")
- Ask Heffernan whether you're being quoted through its standard brokerage or its Thimble-partnered on-demand product. [5](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability")
- Confirm which insurer would issue your policy on Heffernan's standard brokerage path, since that one names none. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")
- Ask Relm's broker which of the listed casualty exclusions apply to your policy specifically. [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance")
