Insurance for PCB Manufacturing & Assembly Facilities (UK Guide)

Introduction: why PCB facilities need specialist insurance

Printed circuit board (PCB) manufacturing and assembly sits in a high-stakes space: tight tolerances, expensive kit, hazardous substances, and customers who rely on your boards to keep their products safe and compliant. One faulty batch can trigger rework, recalls, contractual penalties, and reputational damage.

Whether you run a full fabrication plant (etching, plating, drilling, lamination) or a PCB assembly (PCBA) line (SMT, through-hole, testing, conformal coating), your risks don’t fit neatly into “standard” business insurance. This guide breaks down the main covers UK PCB facilities typically need, what they do (and don’t) pay for, and how to structure a policy that stands up when something goes wrong.

The core covers most PCB manufacturers and assemblers should consider

1) Employers’ Liability (EL) – usually required

If you employ staff in the UK, Employers’ Liability is generally a legal requirement. For PCB operations, EL claims can arise from:

• Exposure to solder fumes, flux, cleaning agents, and other chemicals
• Dermatitis or respiratory issues from sensitising substances
• Manual handling injuries (reels, panels, racking)
• Burns from rework stations, ovens, wave solder, or hot-air tools
• Slips and trips in production areas

Make sure your insurer understands your processes, COSHH controls, and ventilation. A good EL policy is more than a certificate—it’s often the foundation for risk management support.

2) Public Liability (PL) – for third-party injury and property damage

Public Liability covers claims from third parties (visitors, contractors, delivery drivers) for injury or property damage caused by your business. Examples:

• A courier slips in your goods-in area
• A contractor’s equipment is damaged during a site visit
• A visitor is injured during a factory tour

PL is also commonly required by landlords, customers, and site access rules.

3) Products Liability – for damage or injury caused by your boards

Products Liability is essential if you supply PCBs/PCBAs. It covers third-party injury or property damage caused by a defective product.

For PCB/PCBA firms, the tricky part is that many losses are “pure financial” (rework, downtime, recall costs) rather than injury/property damage. That’s where policy wording matters.

Key questions to ask:

• Does the policy include “inefficacy” or “failure to perform” exclusions that could bite?
• Are costs of removing and replacing your product covered (often limited)?
• Are you supplying into safety-critical sectors (medical, aerospace, automotive)? If yes, disclose it.

4) Product Recall / Rectification – when you need to pull stock back

If a defect is discovered after shipment, you may need to notify customers, quarantine stock, arrange returns, and rework or scrap product. Product recall/rectification cover can help with:

• Notification and logistics
• Disposal and rework costs
• Extra labour and overtime
• Some third-party recall expenses (depending on wording)

This cover is particularly relevant if you supply OEMs, contract manufacturers, or distributors who expect fast containment.

5) Professional Indemnity (PI) – for design advice and contractual liability

PCB businesses often provide more than manufacturing:

• DFM/DFT input (design for manufacture/test)
• BOM validation and component substitution advice
• Layout review, stack-up guidance, impedance advice
• Test strategy recommendations

If a customer alleges your advice caused them loss (missed deadlines, failed certification, redesign costs), Professional Indemnity is the policy that typically responds.

PI is also important because many customer contracts push liability onto suppliers for errors, omissions, and “consequential loss” (even when the supplier’s control is limited). You can’t insure away every contract term, but PI helps you avoid a single dispute becoming existential.

6) Property insurance – buildings, contents, and stock

Property cover typically includes:

• Buildings (if you own them)
• Contents (fixtures, racking, office equipment)
• Stock (raw laminate, copper clad, solder paste, components, finished boards)

PCB facilities often have high-value stock concentrations and sensitive storage requirements. Think about:

• Temperature-controlled storage for solder paste and moisture-sensitive components
• Fire load from packaging, plastics, and solvents
• Theft risk for high-value ICs

You’ll want realistic sums insured and a clear basis of settlement (new-for-old vs indemnity).

7) Machinery Breakdown / Engineering insurance – for critical production kit

If your reflow oven, pick-and-place, AOI, X-ray, compressor, or extraction system fails, the repair bill is only half the story. Engineering insurance can cover:

• Sudden and unforeseen breakdown
• Repair or replacement of insured machinery
• Optional business interruption extension for breakdown events

This is often the difference between a manageable incident and a multi-week production stop.

8) Business Interruption (BI) – protecting gross profit and cashflow

BI covers loss of gross profit (or revenue, depending on basis) following insured damage (e.g., fire, flood) and sometimes following machinery breakdown.

For PCB/PCBA firms, BI should be set with:

• A realistic indemnity period (often 12–24 months)
• Consideration of lead times for specialist equipment
• Supply chain dependencies (single-source chemicals, key components)

Also consider:

• Increased cost of working (e.g., outsourcing assembly, expedited freight)
• Loss of rent (if you sublet part of the premises)

9) Cyber insurance – because downtime and data loss are real

PCB operations rely on:

• ERP/MRP systems
• CAD/CAM data, Gerbers, ODB++, pick-and-place programs
• Customer IP and controlled documents
• Email and portals for orders and approvals

Cyber insurance can help with:

• Ransomware response and recovery
• Business interruption from cyber events
• Liability for data breaches
• Incident response support (forensics, legal, PR)

Even if you’re not a “tech company”, you’re a data-rich manufacturer.

10) Goods in Transit and Marine Cargo – for boards and components on the move

If you ship finished boards or receive high-value components, consider cover for:

• Loss or damage in transit (UK and international)
• Courier limitations (often low per parcel)
• Temperature-sensitive shipments

If you import/export, marine cargo can also address customs exposures and broader transit risks.

Common claims scenarios in PCB manufacturing and assembly

Contamination and process errors

A small process drift can create a big batch problem:

• Incorrect solder paste storage leading to poor wetting
• Misaligned stencil or worn squeegee causing insufficient deposits
• Incorrect reflow profile damaging components
• Plating thickness out of spec
• Delamination due to lamination issues

Some of these are “your product is faulty” claims; others are “your advice caused a loss”. Mapping scenarios to the right policy is key.

Fire and smoke damage

PCB sites can have:

• Solvents and cleaning agents
• Ovens and heaters
• Electrical test equipment
• Dust and residues

A small electrical fire can lead to smoke contamination across stock and machinery. Property and BI need to be structured to reflect how quickly you can resume production.

Water damage and humidity

Moisture can ruin:

• Bare boards
• Components
• Packaging

Flooding, burst pipes, or HVAC failure can create large losses quickly.

Contract disputes and chargebacks

Customers may seek:

• Credit notes
• Chargebacks for line stoppage
• Penalties for late delivery
• Costs of rework at their site

Not all of these are insurable. The goal is to reduce the uninsured portion through contract review, clear QC records, and the right mix of PI and product-related covers.

What insurers will want to know (and why it matters)

Underwriters price PCB risks based on process control and loss prevention. Expect questions on:

• Turnover split: fabrication vs assembly vs design services
• Sectors served: medical, aerospace, automotive, defence, consumer
• Quality systems: ISO 9001, AS9100, ISO 13485, IATF 16949
• Traceability: batch/lot control, component traceability, process records
• Testing: AOI, X-ray, ICT, functional test, burn-in
• ESD controls: flooring, wrist straps, audits
• Chemical management: COSHH, bunding, storage, extraction
• Fire protection: alarms, sprinklers, hot works controls
• Subcontracting: who does what, and your contractual responsibility

The clearer and more documented your controls, the easier it is to secure broader cover and better terms.

Key exclusions and gaps to watch for

Insurance is full of “it depends”, but these are common pain points:

• Consequential loss exclusions in product liability (often excludes customer downtime)
• Contractual liability limitations (cover may not extend to liabilities you accept beyond common law)
• Workmanship and wear-and-tear exclusions (engineering policies cover sudden breakdown, not gradual deterioration)
• Known defects and “prior circumstances” (PI won’t cover issues you knew about before inception)
• Recall triggers (some policies require a regulator’s involvement or clear risk of injury)
• Territory and jurisdiction (important if you supply the US/Canada)

A good broker will walk through your typical customer Ts&Cs and align cover to real exposures.

Practical steps to reduce risk (and often premiums)

You don’t need perfection—just evidence of control.

• Documented incoming inspection for critical components
• Controlled storage for moisture-sensitive devices (MSD) and solder paste
• Calibration schedules for ovens, printers, placement machines, and test gear
• Clear rework limits and sign-off process
• Lot traceability from incoming materials to shipped product
• Supplier approval and change control for substitutions
• Fire risk assessment and housekeeping routines
• Segregated chemical storage and spill response plan
• Backups, MFA, and tested disaster recovery for production data

These steps also make claims easier to defend.

How to structure your insurance programme (a simple framework)

A practical way to build your cover is to separate:

1. People risk (EL)
2. Site risk (property, engineering, BI)
3. Customer risk (PL, products, recall)
4. Advice/data risk (PI, cyber)
5. Movement risk (transit/cargo)

Then match limits to your worst-case scenario: the biggest customer contract, the most expensive machine, and the longest realistic downtime.

FAQs: Insurance for PCB manufacturing and assembly

Do I need Professional Indemnity if I only “build to print”?

If you truly only manufacture to customer-supplied specs and you don’t advise on design, substitutions, or testing, PI may be less critical. In practice, many PCB/PCBA firms give informal advice that can create exposure. If you ever approve alternatives, review designs, or provide DFM/DFT feedback, PI is worth serious consideration.

Will product liability cover rework and replacement of faulty boards?

Sometimes, but often with limits and conditions. Many policies focus on injury/property damage, not pure financial loss. Product recall/rectification cover may be needed for rework, logistics, and containment.

What if a customer claims their production line stopped because of our boards?

That’s a classic consequential loss scenario and is frequently excluded under product liability. Some bespoke wordings can soften this, but it’s also a contract management issue—limit liability where you can and keep strong QC evidence.

We store customer-owned components—are those covered?

Not automatically. You may need “customers’ goods” or “goods held in trust” extensions under property insurance. Declare typical and peak values.

Does cyber insurance matter if we’re not taking card payments?

Yes. Ransomware and data loss can stop production, lock you out of CAD/CAM files, and delay shipments. Cyber is about operational resilience as much as privacy.

How much cover do we need?

There’s no one-size-fits-all, but start with:

• Your largest contract value and likely claim size
• The maximum stock value on site
• Replacement cost and lead time for key machinery
• A realistic BI indemnity period (often longer than you think)

Next step: get a PCB facility insurance review

If you run a PCB manufacturing or assembly facility, a quick policy review can uncover gaps around customer contracts, recall exposure, and machinery breakdown.

If you’d like, share:

• Your turnover split (fabrication vs assembly vs design)
• Your main sectors (medical, aerospace, automotive, etc.)
• Your largest single contract value
