Interactive coverage guide

Build a coverage stack around how the business actually operates.

Start with the preselected industry or trade, then adjust the operational questions. The commonly considered stack updates live. Keep the coverages you want GIB to evaluate, remove ones you do not want included in your quote request, and add other available lines before continuing.

Common Starting Coverages

General LiabilityThird-party injury and property damage

What it is

General Liability commonly addresses covered third-party bodily injury, property damage and certain personal or advertising injury claims, subject to the policy.

Why businesses like yours commonly carry it

Businesses commonly use it as a starting liability policy and to satisfy customer, landlord or contract requirements.

Possible coverage gap

General Liability is not intended to replace policies for employee injuries, business vehicles, owned property, cyber events or professional errors.

Professional Liability / E&OErrors in professional services or advice

What it is

Professional Liability may address covered claims alleging errors, omissions or failures in professional services.

Why businesses like yours commonly carry it

Architecture and engineering firms may face claims involving plans, calculations, specifications, coordination or professional judgment.

Possible coverage gap

General Liability is generally not intended to replace coverage for economic loss arising from professional errors.

Commonly Added Based on Operations

Cyber Liability & Data BreachCyber events, data and system interruption

What it is

Cyber insurance may address certain first-party and third-party losses from covered data breaches, cyberattacks, ransomware and system interruption, depending on the policy.

Why businesses like yours commonly carry it

Design firms commonly store client plans, project records and professional work product in connected systems.

Possible coverage gap

General Liability generally should not be assumed to address data breach response, ransomware or network interruption.

Exposure-Dependent Coverages

Business Owners Policy / Commercial PackageLiability and property components evaluated together

What it is

A Business Owners Policy commonly combines liability and property coverages for eligible businesses. A Commercial Package Policy may combine multiple commercial coverage parts depending on the account and carrier.

Why businesses like yours commonly carry it

Businesses with premises, contents, inventory or other property exposures may ask GIB to evaluate whether liability and property components can be packaged where appropriate.

Possible coverage gap

Eligibility, included coverages and package structure vary by carrier. Commercial Property may also be written separately rather than as part of a package.

Umbrella / Excess LiabilityAdditional limits above scheduled liability policies

What it is

Umbrella or Excess Liability may provide additional limits above identified underlying liability policies, subject to its own terms and exclusions.

Why businesses like yours commonly carry it

Businesses with larger contracts, vehicles, public exposure or higher severity potential commonly consider additional limits.

Possible coverage gap

An umbrella does not automatically broaden every exclusion or sit over every policy unless the issued terms say it does.

High-Severity Design Areas

Load calculations, one-lines, grounding, protective-device coordination, fault-current assumptions and emergency power receive close scrutiny.

Data Centers and Critical Facilities

Electrical work for data centers raises severity because redundancy and uptime are contractual priorities.

Utility / Interconnection Work

Substations, medium voltage and on-site generation add schedule and system-integration risk.

Commissioning

Startup and commissioning services should be disclosed because hands-on testing changes the firm's role.

Middle-Market Risk Profile

For commercial electrical firms, underwriters need to know whether the practice is ordinary building power and lighting or includes medium-voltage systems, substations, protection studies, mission-critical design, generators, energy storage, microgrids, controls or utility interconnection. Those distinctions can change both severity and carrier appetite. Firms that combine mechanical, electrical and plumbing design under one roof are covered on MEP engineering firm insurance.

Those distinctions can change both severity and carrier appetite

Contract and Scope Review

Contract language should be reviewed for performance guarantees, energy-savings promises, uptime commitments, coordination responsibility, commissioning obligations and responsibility for owner-furnished equipment. Engineers working for design-build contractors can also inherit schedule and cost pressure not present in a traditional owner-designer relationship.

What Underwriters Should Receive

The submission should identify project sectors, voltage levels, data-center/healthcare percentage, commissioning revenue, utility work, largest project, licensed PE count, subconsultants, claims, design standards, software and quality review of one-line diagrams and protective-device studies.

Three Claim Scenarios to Model

Scenarios worth modeling before marketing or binding this account:

Scenario 1: protective-device coordination error damages equipment
Scenario 2: emergency-power design does not perform during commissioning
Scenario 3: utility interconnection delay is attributed to incomplete engineering

Program Structure Beyond E&O

Professional liability is the core line, but cyber, GL, auto/HNOA, workers compensation and excess can all matter when engineers enter active electrical rooms or client facilities. Larger practices may also need D&O/EPLI and higher professional limits for mission-critical projects.

Large-Firm Underwriting Questions

For a larger electrical practice, the answers help distinguish ordinary building design from mission-critical, utility and commissioning work that may require higher professional limits or specialty underwriting.

What voltage classes are designed?
What percent of revenue is mission-critical work?
Does the firm commission or test energized systems?
Does it design substations or utility interconnections?
What is the largest project construction value?

Frequently asked questions

8 questions — start typing to filter

Why are mission-critical projects higher severity?

Power failures can create substantial delay and business-interruption allegations.

Is commissioning a professional service?

It can be and should be included in the described services.

Does California regulate electrical engineering as a practice act?

Yes; licensing questions should be confirmed with BPELSG.

Should engineers with client-system access buy cyber?

Often yes — an engineer with remote access to a client's building-management or SCADA systems can be blamed for a resulting outage or breach even when the firm's own systems were never compromised.

Can utility coordination create a claim?

Yes if delay or design responsibility is alleged.

Do larger firms need excess professional limits?

Potentially, depending on project and contract requirements.

Does commissioning work change the risk profile?

Yes — commissioning and system startup work adds a hands-on, jobsite-present element to what is otherwise a design-and-documents professional exposure.

Does an arc-flash study create a different kind of exposure than a design drawing?

It tends to, because the deliverable ends up on a label that someone relies on while working energized. An incident energy calculation drives the arc-flash boundary and the PPE category printed on the equipment, and if the model used the wrong available fault current, the wrong protective device settings or data that has since changed, the error is not discovered on paper — it is discovered by a worker. Professional liability generally responds to the negligent act, error or omission in the study itself, while bodily injury to the firm's own staff sits with workers compensation and injury to others with general liability. Studies also age as a facility changes, which is why many agreements set a review interval. What any policy actually covers depends on the form as issued.
