How Insurers Assess Risk in Electronics Manufacturing

Introduction

Electronics manufacturing is a high-value, high-precision business. You may be producing PCBs, sensors, control panels, power supplies, consumer devices, industrial electronics, or components that end up inside medical, automotive, aerospace, or energy systems.

From an insurer’s point of view, that complexity creates two things at once: opportunity (well-run manufacturers can be excellent risks) and uncertainty (small failures can cause big losses). This guide explains how insurers typically assess electronics manufacturing risk in the UK, what they look for during underwriting, and how you can present your business in the best light.

1) The risk picture insurers start with

Underwriters usually begin with a simple question: What’s the worst realistic loss, and how likely is it? In electronics manufacturing, the “worst realistic loss” can come from:

• A major fire or smoke event damaging the building, stock, and specialist machinery
• Water damage to sensitive components and finished goods
• A product defect leading to recalls, third-party property damage, or injury
• Business interruption after a supplier failure, power outage, or equipment breakdown
• Cyber incidents affecting production, design files, or customer data
• Contractual liabilities (penalties, warranties, “fit for purpose” clauses)

Insurers then map those exposures to the covers you’re buying, commonly:

• Property (buildings, contents, stock)
• Business interruption (BI)
• Employers’ liability (EL)
• Public/products liability (PL/Products)
• Product recall and/or product guarantee (where available)
• Professional indemnity (PI) for design, advice, or specification work
• Cyber
• Engineering inspection and breakdown
• Goods in transit and marine cargo

2) What you manufacture (and where it ends up)

Not all electronics are underwritten the same way. Insurers will ask what you make, how it’s used, and who relies on it.

Higher-hazard end uses

Risk tends to rise when your products are used in safety-critical or regulated environments, for example:

• Medical devices and diagnostics
• Automotive systems (especially braking, steering, ADAS)
• Aerospace and defence
• Industrial control systems and power electronics
• Lithium battery systems and chargers

That does not mean cover is unavailable. It means insurers will want more detail on design controls, testing, traceability, and quality management.

Contract manufacturing vs own-brand

Underwriters also differentiate between:

• Contract manufacturing (CM/EMS): You build to a customer’s design/spec.
• Own-brand manufacturing: You design and sell under your brand.
• Hybrid: You do both.

If you design, specify, or modify products, insurers may treat part of your exposure as “professional” (errors in design/specification) as well as “products” (physical failure). This is where PI and products liability need to align.

3) Your processes: where losses usually start

Insurers look closely at the steps where defects, fires, contamination, or downtime can occur.

Common underwriting focus areas

• Soldering and reflow: temperature control, flux management, fume extraction
• Conformal coating and solvents: flammability, storage, ventilation, COSHH controls
• ESD control: grounded workstations, wrist straps, humidity control, packaging
• Cleanliness and contamination: dust control, cleaning processes, ionic contamination testing
• Incoming inspection: counterfeit component controls, supplier approvals
• Burn-in and functional testing: test coverage, calibration, records
• Battery handling (if applicable): storage, charging, thermal runaway controls

Underwriters don’t expect perfection. They want evidence of a controlled process and that you can spot issues early—before a defect becomes a claim.

4) Quality management and traceability

For electronics manufacturing, quality systems are often the clearest signal of risk.

What insurers like to see

• ISO 9001 (and sector standards where relevant)
• Documented procedures and work instructions
• Change control (ECO/ECN) and version control
• Supplier approval and auditing
• Batch/lot traceability for components and finished goods
• Serialisation and test records linked to each unit
• Non-conformance reporting and corrective actions (CAPA)
• Calibration schedules for test equipment

Why traceability matters

If a defect is discovered, traceability can reduce the size of a recall or rework. Instead of pulling every unit shipped over six months, you can isolate a batch, a supplier lot, or a production window. That can be the difference between a manageable incident and a business-threatening loss.

5) Fire, heat, and electrical hazards (property risk)

Property underwriters will focus heavily on ignition sources and how quickly a fire could spread.

Typical questions

• What are the main ignition sources (reflow ovens, wave solder, hot work, battery charging, test rigs)?
• Do you have a hot works permit system?
• Are flammables stored correctly (fire-rated cabinets, quantities controlled)?
• What is the building construction (steel frame, cladding type, compartmentation)?
• Are there sprinklers or other suppression systems?
• What is your housekeeping like (dust, waste, packaging build-up)?

Practical improvements that often help

• Formal hot works controls and contractor management
• Clear separation of flammable storage and production areas
• Regular electrical inspections and PAT where appropriate
• Fire detection suited to the environment
• Good housekeeping and waste removal routines

If your site includes high-value machinery, insurers also consider how easily it can be replaced and how long it would take to get back to production.

6) Business interruption: the “hidden” exposure

Many manufacturers insure the building and equipment but underestimate the time needed to recover.

What insurers assess

• Maximum foreseeable downtime: How long to replace key machines, rebuild clean areas, or re-qualify processes?
• Single points of failure: One reflow line, one test station, one key engineer.
• Supplier dependency: Single-source components, long lead times, overseas shipping.
• Customer concentration: A few large customers can amplify BI impact.

What helps your BI story

• A realistic indemnity period (often 12–24 months for complex manufacturing)
• A documented continuity plan (including alternate suppliers)
• Spares strategy for critical machines
• Off-site backups of design and production data

7) Products liability: how defects become claims

Products liability claims in electronics manufacturing often arise from:

• Overheating, fire, or short-circuit events
• Failure of a safety function
• Incorrect voltage/current output
• EMC issues causing interference
• Incorrect labelling, instructions, or warnings
• Counterfeit or substandard components entering the supply chain

Insurers will ask about:

• End-user markets and territories (UK, EU, US/Canada)
• Any US exposure (often a key rating factor)
• Contract terms, warranties, and limitation of liability clauses
• Testing regimes and compliance (CE/UKCA where relevant)
• Complaint handling and field failure analysis

8) Product recall and rectification

Recall cover is not always standard and can vary widely. Even without a formal “recall” policy, insurers may still look at your ability to manage an incident.

Underwriter interest points

• How quickly you can identify affected units
• Your communication plan (customers, distributors)
• Whether you can repair/replace efficiently
• Whether you have a crisis management process

If you supply into regulated sectors (for example, medical devices), your recall procedures and documentation are especially important.

9) Design responsibility and professional risk

If you provide design services, firmware, PCB layout, or specification advice, insurers may treat this as professional exposure.

Common gaps to avoid

• Products liability excludes pure financial loss (no injury/property damage)
• PI may exclude manufacturing defects unless wording is aligned

A joined-up approach can help ensure you’re protected whether the claim is about faulty advice, faulty design, or a physical product failure.

10) Cyber risk in manufacturing environments

Electronics manufacturers often hold valuable IP (schematics, firmware, BOMs) and may operate connected production systems.

Insurers will look at:

• Backups (including offline/immutable backups)
• Multi-factor authentication (especially for email and remote access)
• Patch management and endpoint protection
• Supplier access controls
• Incident response planning

Even if you’re not a “tech company”, a ransomware incident can stop production and trigger BI losses.

11) People, training, and supervision

Underwriters often ask about:

• Staff experience and turnover
• Training for soldering, inspection, ESD, and safety procedures
• Supervision and sign-off processes
• Use of temporary labour

A stable, trained team reduces both accident risk (EL) and defect risk (products/PI).

12) Site security and theft

Electronics stock can be attractive to thieves, and some components are small, high-value, and easy to move.

Insurers may look for:

• Alarm systems and monitoring
• Access control and visitor management
• CCTV coverage
• Secure storage for high-value items
• Goods-in-transit controls

13) What information insurers typically request

To get the best terms, it helps to present your risk clearly. Insurers commonly ask for:

• A clear description of products and end uses
• Turnover split by product type and territory
• Details of any design responsibility
• Claims history (including near-misses)
• Quality certifications and key procedures
• Testing and inspection details
• Fire protection and building details
• Business continuity and BI figures
• Contract terms and key customer requirements

If you can provide this upfront, you reduce uncertainty—and uncertainty is often what drives higher premiums, higher excesses, or restrictive terms.

14) How to reduce premiums without cutting cover

Insurers respond well to practical risk improvements that reduce frequency and severity.

High-impact actions

• Improve traceability and keep records easy to retrieve
• Strengthen supplier controls and counterfeit component prevention
• Review fire protection and housekeeping routines
• Validate BI sums insured and indemnity period
• Align products liability and PI if you design/specify
• Tighten cyber basics (MFA, backups, patching)

Often, a small investment in controls can do more than shopping the market every year.

FAQs

Do insurers treat electronics manufacturing as high risk?

It depends on what you make and your controls. Safety-critical products, battery work, and high-value machinery can increase risk, but strong quality systems and good fire protection can make you attractive to insurers.

Will exporting to the US affect my premium?

Often, yes. US exposure can increase products liability severity. You may need higher limits, different wording, or specialist markets.

Do I need professional indemnity if I only manufacture?

If you strictly build to a customer’s design and do not advise, design, or modify, PI may be less relevant. But many manufacturers do some level of specification or design support, which can create professional exposure.

What is the biggest mistake companies make with business interruption cover?

Underestimating downtime. Replacing machinery, re-qualifying processes, and rebuilding supplier pipelines can take far longer than expected.

What documents help me get better terms?

Quality certifications, traceability examples, testing records, supplier approval processes, fire risk assessment summaries, and a basic continuity plan are all helpful.
