Key Differences Between Aon and Heffernan

Broker Teams and Buyer Fit

Aon’s Middle Market practice serves mid-sized organizations across North America, while Heffernan describes a specialist technology practice for growth-stage companies and a separate small-business team. Both arrange policies through insurers; neither public description sets eligibility for a particular company. Choose Heffernan if its technology or small-business practice matches your stage and you want to work with its specialist broker. Ask Aon how its Middle Market team would staff and place your account.

Aon markets a dedicated Middle Market practice for mid-sized organizations and says it serves growing businesses across North America. The reviewed page gives no numerical size cutoff and does not establish U.S.-only eligibility; Aon’s broader global client statement describes the parent’s client base, not this practice’s eligibility rules. 4,3Company-reported. Company-reported marketing page, North America; no numerical revenue, employee-count, state or U.S.-only eligibility definition is stated.

Technology companies in mid-to-late stages, including venture-funded and pre-IPO firms, can work with Heffernan’s specialty practice; its small-business team serves sole proprietors through fast-growing firms. 15,21,22,16Company-reported. Current official positioning. Not a minimum-size, funding-stage, or eligibility determination for any applicant.

Heffernan is a broker that shops insurers, presents options and arranges coverage; the policy’s insurer, not Heffernan, issues it and handles covered claims. 20,23,19,15Company-reported. Company-described broking role. Do not infer underwriting authority for all products from the marine-cargo program’s in-house authority language.

Claims and Account Service

Heffernan describes claims consulting from intake through resolution, including carrier liaison, and says clients can receive claims, loss-control and risk support. Aon’s U.S. terms place direct insurer notice with the client unless a separate written agreement changes that duty. These statements describe different service responsibilities, not a comparison of claim outcomes: the insurer and policy control coverage. Confirm the named producer and who will manage renewals, certificates and claim notices before choosing a service model.

Heffernan describes claims consulting from intake through resolution, including carrier liaison and medical triage; its marine-cargo program separately claims authority to adjust, settle and pay. These are service claims, not a promise that your loss is covered. 24,30Company-reported. Company descriptions of advocacy and a specialty cargo claims unit. Speed, “$1 billion managed,” and “up to 75% faster” figures are not adopted as verified performance.

Heffernan says clients receive claims, loss-control, HR and risk-management support, with digital access to documents and certificates; confirm which tools and services your engagement includes. 20,37,24Company-reported. Official feature descriptions only; no authenticated client account or measured service levels.

Under Aon’s U.S. brokerage terms, the client is responsible for directly notifying insurers as its policies require unless a separate signed agreement says otherwise; Aon says it does not assume that notice or monitoring duty without a separate written agreement. This allocation does not determine whether Aon separately offers or agrees to claims advocacy or other claims-related services. 1,5,7Company-reported. Company-reported contractual allocation for covered U.S. Commercial Risk services; policy terms and any separate written agreement control. Aon separately describes claims advocacy on its D&O and cyber pages.

What to Confirm in Quotes

  • Ask Heffernan for the contracting producer, state/product eligibility and the services included with your account; its public technology pages do not provide a product-by-state map. 15 21
  • Ask Aon whether any separate signed agreement changes the client’s insurer-notice responsibility. 1
  • Request placement-specific compensation and any separately billed service from both brokers; neither source set establishes a standard account fee. 26 1

What each provider documents about the services you may need

CriteriaAonHeffernan Insurance Brokers
Business role

Aon’s U.S. Commercial Risk terms describe Commercial Risk Solutions U.S. as broker of record for certain insurance programs. Separate electronic-delivery terms name Aon Risk Services Companies, Inc. acting for itself and licensed brokerage subsidiaries to deliver arranged policies; the terms define an insurer as the policy issuer and risk bearer. These group-level descriptions do not identify the producer or authority for a particular placement. 1,2Company-reported. Company-reported U.S. Commercial Risk brokerage and electronic-delivery terms; certain programs only. No specific insured, licensed producer, appointment, policy issuer, state authority or placement was matched.

Heffernan is a broker that shops insurers, presents options and arranges coverage; the policy’s insurer, not Heffernan, issues it and handles covered claims. 20,23,19,15Company-reported. Company-described broking role. Do not infer underwriting authority for all products from the marine-cargo program’s in-house authority language.

Confirm the exact producer on your agreement and policy: Heffernan’s pages use that business name and display California license 0564249 but no longer corporate suffix. 15,38,16Company-reported. Brand and license-number display only. Not independent license verification or a complete legal-entity chart.

Heffernan describes itself as employee-owned and independent since 1988; a 2019 investor release described a minority investment, but current ownership percentages are not public. 15,16,39Company-reported. Company and investor announcements. Not a current cap-table verification.

If you need California technology insurance, verify which related Heffernan entity will serve as producer; its network, London, and benefits entities do not identify the entity for your policy. 35,36,25,17Company-reported. Official related-entity descriptions. Costero’s FCA status and Heffernan’s exact current ownership of Costero were not independently verified.

Customer focus

Aon markets a dedicated Middle Market practice for mid-sized organizations and says it serves growing businesses across North America. The reviewed page gives no numerical size cutoff and does not establish U.S.-only eligibility; Aon’s broader global client statement describes the parent’s client base, not this practice’s eligibility rules. 4,3Company-reported. Company-reported marketing page, North America; no numerical revenue, employee-count, state or U.S.-only eligibility definition is stated.

Technology companies in mid-to-late stages, including venture-funded and pre-IPO firms, can work with Heffernan’s specialty practice; its small-business team serves sole proprietors through fast-growing firms. 15,21,22,16Company-reported. Current official positioning. Not a minimum-size, funding-stage, or eligibility determination for any applicant.

Application process

For certain U.S. Commercial Risk programs, Aon says it consults with the client about market conditions, insurers to approach and program strategy, helps prepare underwriting information and applications, and obtains the client’s instructions to bind specific programs based on Aon’s proposal. The client signs applications that require a signature. 1Company-reported. Company-reported contractual terms for certain U.S. Commercial Risk programs; not a universal workflow, online checkout claim, insurer role or guarantee that a quote can bind.

You can start with an inquiry form asking for contact details, insurance needs and an operations description; the form was not submitted, so quote results and binding steps were not established. 26Verified. Chrome inspection of the unsubmitted Contact Form 7 on heffins.com/contact-us/. No fields completed and no submission. Downstream underwriting and post-submission behavior not tested. The wording was checked against the stored inspection record on 24 September 2026; the website was not revisited.

Technology buyers work with a specialist broker who gathers insurer quotes and helps choose coverage; Heffernan does not promise a universal quote or binding time for growth-stage programs. Quick Insure is a separate path for selected personal and short-term business products. 21,23,27,26Company-reported. Service descriptions. Technology-page FAQ “how do I get” language is educational process copy, not a measured SLA.

Servicing and renewals

Aon says it consults with clients before placing or renewing coverage and, where applicable, administers the insurer relationship for selected programs, including billing, data reporting and negotiated requirements. The terms do not promise automatic renewal, a timetable, a specific market or a particular outcome. 1Company-reported. Company-reported terms for selected U.S. Commercial Risk programs; administration varies where applicable and may be changed by written agreement.

Heffernan says clients receive claims, loss-control, HR and risk-management support, with digital access to documents and certificates; confirm which tools and services your engagement includes. 20,37,24Company-reported. Official feature descriptions only; no authenticated client account or measured service levels.

Claims assistance

Under Aon’s U.S. brokerage terms, the client is responsible for directly notifying insurers as its policies require unless a separate signed agreement says otherwise; Aon says it does not assume that notice or monitoring duty without a separate written agreement. This allocation does not determine whether Aon separately offers or agrees to claims advocacy or other claims-related services. 1,5,7Company-reported. Company-reported contractual allocation for covered U.S. Commercial Risk services; policy terms and any separate written agreement control. Aon separately describes claims advocacy on its D&O and cyber pages.

Heffernan describes claims consulting from intake through resolution, including carrier liaison and medical triage; its marine-cargo program separately claims authority to adjust, settle and pay. These are service claims, not a promise that your loss is covered. 24,30Company-reported. Company descriptions of advocacy and a specialty cargo claims unit. Speed, “$1 billion managed,” and “up to 75% faster” figures are not adopted as verified performance.
