Key Differences in Professional Liability (E&O) Insurance

A Family of Named Products Versus One Product

Relm groups a family of professional-liability products under Professional Lines and Errors and Omissions, distinguishing a general E&O line from specialized versions for accountants, consultants, and financial institutions, among other niches. 9 At-Bay instead names Miscellaneous Professional Liability (MPL) as a single product with its own coverage-highlights list, without splitting it into profession-specific sub-products. 3

Named Regulatory Requirements Versus a General Appetite

Relm notes that some professionals, including attorneys, are required by federal or state law to carry errors and omissions insurance, and that its Financial Institutions Professional Indemnity is mandated by some regulators, including the UK's Financial Conduct Authority. 9 At-Bay's MPL page instead describes eligibility generally as businesses of all revenue sizes, without naming a specific regulatory mandate tied to the coverage. 3

What Neither Page Names

Relm's reviewed page does not name a specific issuing insurer for E&O placements. 9 At-Bay's current MPL page similarly does not name the insurer for a new quote. 3

What to Confirm in Professional Liability (E&O) Insurance Quotes

  • Ask Relm which of its named sub-products — general E&O, Accountants E&O, or Consultants E&O — matches your business. 9
  • Ask At-Bay directly which insurer would issue your MPL policy. 3
  • Ask Relm which insurer would place your specific sub-product, since its page does not name one. 9
  • Ask At-Bay for its published $5 million limit ceiling and applicable state restrictions. 3
  • If a client contract or regulator requires E&O, confirm which of Relm's products satisfies that specific requirement. 9

Role in This Line

At-Bay markets MPL as one of its own named insurance products, sold through its disclosed producer, At-Bay Insurance Services LLC, with the product page directed at "properly licensed insurance professionals" submitting business rather than at direct retail buyers. 3,4Company-reported. Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk.

Relm groups a family of professional liability products under Professional Lines and Errors and Omissions, distinguishing a general E&O line from specialized versions for accountants, consultants, financial institutions, lawyers, lenders, media, trust/fund administrators and other niches. 9Company-reported. Relm line-of-business page (Relm sells through brokers); not a statement identifying the issuing insurer for a given placement. This record covers the general 'Errors and Omissions' and 'Consultants' and 'Miscellaneous' entries; Relm's media and lawyers E&O sub-products are addressed in separate offering records where scoped.

Issuing Insurer

The current MPL product page does not name the insurer that issues the policy. A September 2023 press release named United Specialty Company in connection with MPL, but that historical reference does not establish the current issuing insurer for a new MPL quote. 3,5Not found in reviewed sources. Reviewed MPL page as of 2026-09-23 and the September 2023 press release; restates the existing provider fact that MPL's current issuer is unresolved, distinct from the August 2023 Cyber/Tech E&O transition to At-Bay Specialty Insurance Company paper.

The reviewed page does not name a specific issuing insurer for E&O placements. 9Not publicly disclosed. Line-of-business page as read on 2026-09-23; a specific placement's insurer is product- and jurisdiction-specific.

Who It’s For

At-Bay says it provides primary MPL for businesses of all revenue sizes with limits up to $5 million, subject to state restrictions and eligibility requirements detailed in a separate MPL appetite guide. 3Company-reported. Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record.

Relm targets clients in emerging sectors such as space, digital assets, AI and biotech, describing general E&O as protection for the provision of specialized products, advice or services, and Miscellaneous E&O for niche fields like robotics consulting and space logistics that don't fit an established category. 9Company-reported. Professional Lines page framing; not a guarantee of eligibility for a particular company.

Relm notes that some professionals, including attorneys, are required by federal or state law to carry errors and omissions insurance, and that Financial Institutions Professional Indemnity is mandated by some regulators, including the UK's Financial Conduct Authority. 9Company-reported. Professional Lines page; general regulatory context, not a jurisdiction-specific legal determination for a particular buyer.

Coverage Features

At-Bay lists MPL coverage highlights including automatic coverage for acquired subsidiaries, claims-made-and-reported coverage, coverage for independent contractors, disciplinary-proceedings defense, a duty-to-defend contract, personal-injury coverage (including emotional distress), punitive damages where insurable, a professional-services definition written for each insured, and an 80/20 hammer clause. 3Company-reported. Product-page coverage-highlights list; an 80/20 hammer clause is a settlement provision where the insurer pays 80% and the insured pays 20% of costs after the insured declines a recommended settlement. The issued policy and declarations control actual wording, limits and exclusions.

Relm says its general E&O line covers claims of professional negligence, mistakes or faulty recommendations, and failure to deliver on agreed services, while Consultants E&O specifically defends against allegations of negligence, poor advice or failure to deliver adequate services. 9Company-reported. Professional Lines page general description; the issued policy and declarations control.

Relm describes a distinct Accountants Errors and Omissions product covering misconduct accusations, financial misstatements, miscalculations, late filings, and in some cases breach of contract, including legal defense costs, settlements and damages. 9Company-reported. Professional Lines page 'Accountants Errors and Omissions' section; a related but separate product from Relm's general E&O line.

Limits and Retentions

At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. 3Company-reported. Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant.

Not described in the reviewed sources.

How to Apply

At-Bay directs MPL submissions to underwriting by email or through automatic quotes on its Broker Platform, which At-Bay describes as a workflow of creating a quote, customizing limits and retentions, and binding the policy. 3,6Company-reported. Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed.

Not described in the reviewed sources.
