THE 3 MAIN LIABILITY POLICIES (AND WHY THEY’RE NOT THE SAME)

Why This Comparison Matters for Electrical Component Manufacturers

Manufacturers often assume “liability insurance is liability insurance” — until a claim happens and the insurer points to the wrong section, the wrong trigger, or a pollution exclusion. Electrical component businesses have multiple “ways to cause loss”: a product defect in the field, an accident during site work, or a spill/contamination event. Each is normally addressed by a different liability policy.

This page explains the differences in plain English and shows you how to structure cover so you don’t discover a gap at the worst possible moment. It’s especially relevant if you manufacture or supply switchgear, control panels, sensors, instrumentation, connectors, power supplies, cable assemblies, PCBs, enclosures, chargers, or electronic sub-assemblies — where products can be embedded into high-value systems and your site activities can be closely controlled by customers.

If you want an expert review, Insure24 can check your current documents and identify whether your programme is correctly aligned, including territories, limits, indemnity clauses, pollution wording, and how “work away” or contracting exposures are described.

Quick Definitions: What Each Policy is Designed to Cover

These policies respond to different triggers. The key is identifying what caused the incident and what type of damage occurred. Most standard liability policies focus on injury and property damage — but they differ on whether the cause is your activities, your products, or a pollution condition.

Public Liability (Third-Party Liability)

Public liability is designed to cover your legal liability for injury to third parties or damage to third-party property arising from your business activities. Think: premises risks, site visits, deliveries, demonstrations, installation/commissioning (where included).

  • Visitor injury at your factory or offices
  • Accidental damage to client property during site work
  • Third-party injuries during demonstrations or training
  • Legal defence costs for covered claims

Product Liability

Product liability is designed to cover your legal liability for injury or property damage caused by products you manufacture, supply or sell after they leave your control. Think: defects, failures, safety issues, wrong specifications, or manufacturing faults that cause harm.

  • A defective component causes damage to third-party equipment
  • A product failure leads to injury (e.g., shock, burns) and you are held liable
  • Claims from customers or third parties alleging defective manufacture
  • Legal defence costs for covered product claims

Environmental / Pollution Liability

Environmental liability (pollution legal liability) is specialist insurance designed for pollution conditions, clean-up and remediation costs, and related third-party claims and regulatory actions. It can be structured to cover gradual pollution and on-site clean-up — areas that standard liability policies often exclude.

  • Spills to drains or land requiring clean-up and sampling
  • Off-site migration to neighbouring land or watercourses
  • First-party remediation at your own premises (where included)
  • Regulatory investigation and defence costs

What This Guide Does (and Doesn’t) Cover

This page focuses on the main differences between the three liability covers. In practice, manufacturers also commonly need: employers’ liability (for staff injuries), professional indemnity (design/specification risk), product recall/rectification (field failure costs), and cyber (ransomware/OT disruption).

  • Employers’ liability = staff injuries (usually legally required)
  • Professional indemnity = advice/design/specification issues
  • Product recall = the practical costs of removing/repairing products
  • Cyber = data/IT/OT incidents and associated liabilities

Side-by-Side Comparison (Simple Version)

Use this as a quick decision tool when you’re unsure which policy is relevant. The real answer depends on your wording, but the table below reflects typical intent and most common triggers in UK commercial insurance.

Public Liability

  • Trigger: your business activities (premises, site visits, deliveries)
  • Typical damage: third-party injury or third-party property damage
  • Common examples: trip hazards, accidental damage while commissioning
  • Common gap: pollution exclusions and contracting scope issues
  • Who asks for it: customers, principal contractors, site operators

Product Liability

  • Trigger: defect/failure in your product after it leaves your control
  • Typical damage: injury or property damage caused by the product
  • Common examples: overheating, arcing, insulation failure damaging equipment
  • Common gap: pure financial loss and recall/rectification costs
  • Who asks for it: OEMs, distributors, large customers, export buyers

Environmental Liability

  • Trigger: pollution condition (sudden or gradual depending on wording)
  • Typical damage: clean-up costs, third-party claims, regulatory action
  • Common examples: solvent/oil spill to drains, contaminated fire water run-off
  • Common gap: assumptions that public liability covers clean-up
  • Who asks for it: some contracts, landlords, high-risk sites, regulated sectors

Where Manufacturers Get Caught Out

  • Policy schedule describes “manufacturing only” but you do commissioning or on-site work
  • Territory excludes USA/Canada yet your products are resold there
  • Product liability limit meets contract, but exclusions remove key exposure
  • Pollution exclusions block clean-up costs following a spill
  • No professional indemnity despite design/specification responsibility
  • No product recall/rectification cover despite embedded installed-base risk

Claim Scenarios: Which Policy Would Typically Respond?

These examples are common in electrical component manufacturing. They show how the “cause” of loss determines which policy is relevant. Your actual response depends on policy wording, exclusions, and how your business is described to insurers.

Scenario A: Visitor Injured at Your Factory

A customer visits your premises for a factory acceptance test and trips on a cable route in a workshop area. They claim medical costs and lost earnings.

  • Most likely policy: Public Liability
  • Why: injury arises from premises/activities, not a defective product in the field
  • Common issue: ensuring contractors/visitors are included and site is described correctly

Scenario B: Defective Component Damages Customer Equipment

A connector or power device fails after installation, causing damage to a customer’s machine and downtime. They allege a manufacturing defect.

  • Most likely policy: Product Liability
  • Why: damage arises from a defective product after it left your control
  • Common issue: “pure financial loss” / contractual downtime may not be covered

Scenario C: Spill to Drain Requires Clean-up and Sampling

A drum of cleaning solvent is knocked over in stores and enters a drain. Emergency response is required and regulators request sampling and reports.

  • Most likely policy: Environmental / Pollution Liability
  • Why: the key cost is clean-up/remediation and regulatory response
  • Common issue: public liability may exclude or sub-limit pollution

Scenario D: Damage During Commissioning at Customer Site

While commissioning a control panel, a tool slips and damages a customer’s equipment. The customer claims the repair costs.

  • Most likely policy: Public Liability (if “work away” / contracting activity is included)
  • Why: damage arises from your activity on site, not product defect after handover
  • Common issue: policy described as “manufacture only” can create a gap

If you’re unsure, the most important step is to align the policy description with your real-world activities: manufacture, supply, installation, commissioning, servicing, training, and the territories your products reach (including resale routes).

How to Structure Liability Insurance for an Electrical Manufacturer

The best structure depends on your products, contracts, territories and what you do away from site. Below is a practical approach we use with clients to reduce gaps and avoid duplicate cover.

Step 1: Map Your Exposures

  • Premises risk: visitors, contractors, loading bays, forklifts
  • Work away: installation, commissioning, servicing, training
  • Product risk: defects, failures, safety issues, downstream integration
  • Pollution risk: solvents/oils, batteries, waste streams, drainage proximity
  • Professional risk: design/spec, advice, calibration, performance representations

Step 2: Align Policies to Triggers

  • Public liability: activities and premises
  • Product liability: products in the field
  • Environmental liability: pollution conditions and clean-up
  • Professional indemnity: design/spec/advice and financial loss
  • Product recall: practical costs of field action / rectification

Step 3: Get Limits & Territory Right

  • Match limits to customer contract requirements (often £5m–£10m)
  • Confirm territory: UK, EU, worldwide (and USA/Canada if needed)
  • Consider “indemnity to principals” and contract clauses
  • Review pollution wording and any sub-limits carefully
  • Clarify whether “work away” is included or excluded

Step 4: Avoid Common Gaps

  • Don’t rely on public liability for pollution clean-up
  • Don’t assume product liability covers recall/rectification costs
  • Don’t omit PI if you have design/spec responsibility
  • Don’t understate your on-site work (commissioning is still contracting)
  • Don’t ignore distribution chains that create overseas exposure

We thought our “liability policy” covered everything. Then we had a spill incident and discovered clean-up costs weren’t covered the way we expected. Insure24 helped us structure public, product and environmental liability correctly — and it’s far clearer now.

FREQUENTLY ASKED QUESTIONS

+-

Do I need both public and product liability insurance?

Most manufacturers do. Public liability relates to incidents arising from your activities (premises, site visits, deliveries, commissioning), while product liability relates to injury or property damage caused by your products after they leave your control.

+-

Does product liability cover the cost of recalling or replacing products?

Typically not. Product liability is designed for third-party injury and property damage claims. The practical costs of recall/rectification and field actions are usually covered under specialist product recall/rectification insurance (if arranged), subject to wording.

+-

Is pollution covered by public liability insurance?

Sometimes only in a limited way (often sudden and accidental only) and many policies restrict or exclude gradual pollution and specialist clean-up costs. Environmental liability insurance is designed for pollution conditions, clean-up/remediation, and regulatory defence.

+-

If I do commissioning work, is that public liability or product liability?

Commissioning and on-site work is typically considered an “activity” exposure, so public liability (and contracting scope) is usually relevant for accidental damage/injury during the work. Product liability relates to defects in the product after it has left your control. The wording and how your activities are described is critical.

+-

Do I need environmental liability if I don’t use “heavy chemicals”?

Possibly. Many electrical manufacturers still store solvents, oils, resins, batteries and hazardous waste streams. Even small spills can become expensive due to sampling, specialist contractors and reporting requirements. The need depends on your operations and premises risk.

+-

Can Insure24 review my current policies and identify gaps?

Yes. We can review your schedule and key policy sections, confirm how your activities are described, check territories and limits, and identify where additional cover (such as PI, recall/rectification, or environmental liability) may be needed based on how you trade.
