Insurance for Microprocessor Factories & Electronics Technology Manufacturing
Microprocessor factories and electronics technology manufacturers sit at the very heart of the modern economy. From the semiconductors powering medical devices to the circuit boards inside industrial control systems, the UK's electronics manufacturing sector is a high-value, high-complexity environment where the stakes — and the risks — are exceptional.
Yet for many business owners in this sector, insurance remains an afterthought. Policies are renewed without review, gaps in cover go unnoticed, and the sheer technical nature of the operation makes it difficult to know whether a standard commercial policy will actually respond when something goes wrong.
This guide breaks down the key risks facing microprocessor and electronics manufacturers in the UK, the cover types you should have in place, and the questions worth asking before your next renewal.
The Scale of Risk in Electronics Manufacturing
Electronics and microprocessor manufacturing is not a sector where risk is theoretical. The combination of precision machinery, clean-room environments, hazardous materials, complex supply chains, and highly specialised workforces creates an unusually dense risk profile.
Consider a few scenarios that are far from uncommon:
- A power surge damages a bank of semiconductor fabrication equipment, causing a production halt lasting several weeks. Replacement parts are on back order from overseas suppliers.
- A batch of microprocessors passes quality control but contains a latent defect. They are installed into client products, which subsequently fail in the field. Your customer issues a claim for recall costs, loss of revenue, and reputational damage.
- A fire breaks out in a soldering area due to a flux residue ignition. The clean room is contaminated, machinery is damaged, and the business cannot fulfil outstanding orders.
- An employee develops occupational dermatitis from prolonged exposure to chemical solvents used in the manufacturing process. They bring an employers' liability claim.
- A cyber attack targets your SCADA or production management systems, halting the production line for days and compromising proprietary design data.
Each of these scenarios involves a different class of insurance — and without the right policy structure, any one of them could result in an uninsured loss running into hundreds of thousands of pounds.
Property and Plant Insurance
The physical assets of an electronics manufacturer are typically among its most valuable. Microprocessor fabrication equipment, automated assembly lines, pick-and-place machines, reflow ovens, testing rigs, and clean-room infrastructure represent enormous capital investment. A single photolithography machine used in semiconductor production can cost millions of pounds.
Your property insurance must be built on an accurate and up-to-date reinstatement value — not market value. If your premises or equipment is underinsured, any claim will be subject to the averaging principle, meaning your insurer will only pay a proportionate share of your loss.
What your property cover should include:
- Buildings cover for the manufacturing facility, including clean rooms, offices, and storage areas
- Contents cover for tools, computers, office equipment, and furnishings
- Plant and machinery cover for fabrication, assembly, and testing equipment
- Stock cover for raw materials (silicon wafers, chemical compounds, components), work in progress, and finished goods
- Electronic equipment insurance, where standard fire-and-theft policies may fall short on specialist machines
It is also worth reviewing whether your policy covers damage resulting from contamination — particularly important in clean-room environments where particulate ingress following a fire or flood can render an entire production area unusable even if direct fire damage is minimal.
Business Interruption Insurance
For electronics manufacturers, the financial impact of a production halt almost always exceeds the cost of physical damage. Customers have delivery schedules to meet, and if you cannot supply, they will source elsewhere — often at your expense.
Business interruption insurance compensates for the loss of gross profit during the period it takes to restore operations following an insured event. Getting this right requires careful thought about two key variables:
Indemnity period: This is the maximum length of time the policy will pay out. For a microprocessor manufacturer, where specialist equipment may have lead times of 12 to 24 months, a 12-month indemnity period is almost certainly insufficient. Most manufacturers in this sector should consider a minimum 24-month indemnity period, with 36 months being more appropriate for those with highly specialised production infrastructure.
Sum insured: Your business interruption sum insured should reflect your gross profit over the full indemnity period — not just one year. Underinsuring this figure is one of the most common and costly mistakes electronics manufacturers make.
Extensions worth considering include:
- Suppliers extension: Covers loss of profit if a key supplier suffers a loss that prevents them from delivering critical components to you
- Customers extension: Covers loss if a major customer suffers a loss that reduces their orders from you
- Utilities extension: Covers loss resulting from failure of power, gas, or water supply from an external provider
- Denial of access: Covers loss where a nearby incident (such as a fire at a neighbouring premises) prevents access to your site
Product Liability Insurance
Product liability is arguably the most significant long-tail risk facing microprocessor and electronics manufacturers. Once your products leave the factory, you lose direct control over how they are used — and if they cause damage or injury, the consequences can be severe.
UK law under the Consumer Protection Act 1987 imposes strict liability on manufacturers for defective products that cause death, personal injury, or damage to private property. You do not need to have been negligent — if the product is defective and causes loss, you are potentially liable.
For electronics manufacturers, the key product liability risks include:
- Latent defects: Manufacturing faults that are not detectable at the time of quality inspection but cause failure in the field — sometimes years after the product left your facility
- Design defects: Where the product was manufactured correctly but the underlying design causes harm
- Failure in safety-critical applications: Microprocessors and electronic components are used in medical devices, automotive systems, aviation, and industrial control — sectors where failure can have catastrophic consequences
- Product recall costs: If a batch of defective products must be recalled, the costs of notification, logistics, and replacement can be enormous — and are often not covered by a basic public liability policy
When arranging product liability insurance, check:
- The geographic scope of cover — particularly if you export to the USA, where product liability claims can be of a very different magnitude
- Whether recall costs are included or available as an extension
- The limits of indemnity — are they adequate for the applications your products are used in?
- Whether there are any exclusions for products incorporated into other items or used in specified industries
Employers' Liability Insurance
Employers' liability insurance is a legal requirement for any business with employees in the UK. You must hold a minimum of £5 million of cover, and the certificate must be displayed (physically or electronically) in your workplace.
Electronics manufacturing presents a range of occupational health hazards that make employers' liability claims more likely than in many other sectors:
- Chemical exposure from solvents, flux, etching acids, and cleaning agents
- Repetitive strain injuries from assembly line work
- Eye strain and fatigue from microscopy and precision inspection tasks
- Noise exposure in high-volume production environments
- Electrical hazards during testing and rework procedures
- Manual handling injuries in warehouse and logistics functions
A robust health and safety programme — including COSHH risk assessments, PPE provision, and training records — is your first line of defence. Good documentation also plays a significant role in defending employers' liability claims when they do arise.
Engineering Inspection and Machinery Breakdown Cover
Many businesses do not realise that certain statutory inspection obligations — for pressure vessels, lifting equipment, and electrical installations — sit alongside their insurance arrangements. An engineering inspection contract ensures these legal requirements are met while also providing evidence of compliance.
Machinery breakdown insurance covers the cost of repairing or replacing plant and equipment following sudden and unforeseen mechanical or electrical breakdown. This is distinct from property insurance, which covers damage caused by fire, flood, or theft — not internal mechanical failure.
For microprocessor manufacturers, where a single piece of equipment failure can halt an entire production line, machinery breakdown cover can be the difference between a manageable incident and a catastrophic one. Cover should extend to:
- Fabrication and etching equipment
- Automated assembly machinery
- Test and measurement equipment
- Climate control systems for clean rooms
- Uninterruptible power supply (UPS) systems
- Computer systems used in process control
Many machinery breakdown policies can also be extended to cover the consequential business interruption losses arising from the breakdown — ensuring you are protected for both the repair cost and the lost revenue during downtime.
Cyber Insurance for Electronics Manufacturers
The electronics manufacturing sector is increasingly targeted by cyber criminals. Intellectual property — design files, process recipes, proprietary firmware — is highly valuable, and the integration of operational technology (OT) and information technology (IT) in modern factories creates attack surfaces that traditional IT security was not designed to protect.
The risks are significant:
- Ransomware attacks on production management systems, halting manufacturing operations
- Espionage and IP theft, with competitors or state-sponsored actors targeting proprietary designs
- Supply chain attacks via software updates or compromised components from third-party suppliers
- Data breaches involving customer technical specifications or employee personal data
- OT/SCADA attacks that could cause physical damage to equipment or safety incidents on the production floor
A specialist cyber insurance policy provides cover for:
- Incident response costs, including forensic investigation and legal advice
- Business interruption losses arising from a cyber event
- Data breach notification costs and regulatory defence expenses
- Cyber extortion and ransomware payments
- Third-party liability where client data or systems are affected
- PR and crisis management costs
UK electronics manufacturers should also ensure their cyber security practices meet the requirements of the UK GDPR and the Network and Information Systems (NIS) Regulations where applicable — both of which carry their own regulatory penalties for failures.
Professional Indemnity Insurance
Electronics manufacturers who design bespoke products, provide technical consultancy, or develop firmware and embedded software for clients should strongly consider professional indemnity (PI) insurance.
Where your business moves beyond pure manufacturing into design, specification, or advisory services, you take on professional liability. If a client suffers a financial loss as a result of an error in your design, a specification failure, or flawed technical advice, they may bring a claim against you regardless of whether the product itself was physically defective.
PI insurance covers your legal defence costs and any damages or settlements arising from such claims. For businesses working in safety-critical sectors — medical devices, automotive, aerospace, or industrial control — this cover is particularly important, as the consequences of design failures in these applications can be severe and the claims correspondingly large.
Transit and Marine Cargo Insurance
Electronics components and finished products are high-value, often fragile, and regularly shipped over long distances. Whether you are importing silicon wafers and rare earth materials, shipping finished microprocessors to European clients, or exporting to global markets, your goods are at risk during transit.
Standard property policies typically do not cover goods in transit beyond a nominal amount. A dedicated marine cargo or goods-in-transit policy ensures your stock is covered from despatch to delivery, including:
- All-risks cover during road, rail, sea, and air transit
- Loading and unloading risks
- Temporary storage at third-party warehouses or hubs
- Exhibition and trade show attendance
For businesses with significant import or export activity, an open cargo policy — which automatically covers all shipments — is generally more cost-effective and administratively simpler than arranging cover voyage by voyage.
Directors and Officers Liability
Directors and senior managers of UK electronics manufacturing companies carry personal legal liability for decisions made in the course of running the business. Regulatory investigations, shareholder disputes, health and safety prosecutions, and employment tribunal claims can all give rise to personal liability that falls outside the company's commercial insurance.
Directors and officers (D&O) insurance covers the personal legal costs and any resulting awards against directors and officers, and can also cover the company itself for losses arising from claims made against it in relation to its directors' conduct.
For companies operating in the electronics sector — with obligations under WEEE regulations, RoHS directives, Health and Safety legislation, and data protection law — D&O cover is a sensible addition to any comprehensive insurance programme.
Environmental Liability Insurance
Electronics manufacturing involves the use of chemicals and materials that can cause environmental damage if they escape into soil, waterways, or the atmosphere. Solvents, acids, heavy metals, and refrigerants all carry environmental liability risk.
Environmental liability insurance covers the costs of cleaning up pollution caused by your operations, as well as third-party claims for damage caused by contamination spreading from your site. With increasing regulatory scrutiny from the Environment Agency and potential civil claims from affected neighbours or businesses, this is cover worth considering — particularly for larger manufacturing operations or those operating on sites with legacy contamination concerns.
Reviewing Your Insurance Programme
An insurance programme for a microprocessor factory or electronics technology manufacturer should never be a one-size-fits-all arrangement. The right cover depends on:
- The nature of your products and the industries they serve
- The value and specialisation of your plant and equipment
- Your supply chain — both upstream (suppliers) and downstream (customers)
- The geographic markets you operate in and export to
- Your intellectual property and the extent of your design and consultancy activity
- Your workforce size, composition, and the hazards they face
- Your cyber security posture and the level of OT/IT integration in your operation

Frequently Asked Questions
Is product liability insurance a legal requirement for electronics manufacturers in the UK?
Product liability insurance is not legally required, but it is strongly advisable and in many cases commercially essential. The Consumer Protection Act 1987 imposes strict liability on manufacturers for defective products, and many commercial contracts — particularly with large buyers or in regulated industries — require you to hold a minimum level of product liability cover as a condition of trading.
What level of product liability cover do I need as a microprocessor manufacturer?
The right limit depends on your customer base and the applications your products are used in. For manufacturers supplying components used in medical devices, automotive systems, or industrial machinery, limits of £5 million to £10 million per occurrence are a common starting point, but higher limits may be necessary where exposure to the US market exists or where the consequences of failure are particularly severe.
Does my standard property policy cover machinery breakdown?
No. Standard property policies cover damage caused by insured perils such as fire, flood, or theft. Internal mechanical or electrical breakdown is a separate risk requiring dedicated machinery breakdown cover. Without it, the cost of repairing or replacing failed production equipment — and the associated loss of profit — falls entirely to the business.
Does business interruption insurance cover delays caused by supply chain problems?
Standard business interruption policies only respond to interruption caused by physical damage at your own premises. Cover for supply chain disruption — where a supplier suffers a loss that prevents them from delivering to you — requires a suppliers extension to be added to your policy. Given the complexity and globalisation of electronics supply chains, this extension is worth serious consideration.
Are we covered if a cyber attack targets our production control systems rather than our IT network?
This depends heavily on how your cyber policy is worded. Many standard cyber policies were written with IT systems in mind and may not explicitly cover operational technology (OT) environments. If your business relies on SCADA, PLCs, or other OT systems, it is important to confirm with your insurer that these are within the scope of your cyber cover — and to request appropriate endorsements if they are not.
What is the RoHS directive and does it affect our insurance?
The Restriction of Hazardous Substances (RoHS) directive restricts the use of specific hazardous materials in electrical and electronic equipment sold in the UK and EU. A breach of RoHS compliance could give rise to regulatory fines and civil claims from customers — exposures that a product liability and professional indemnity programme should be structured to address.
Do I need separate cover for goods exported to the United States?
Yes, in most cases. US product liability exposure is materially different from UK exposure — claims are more frequent, legal costs are higher, and damages awards can be significantly larger. Many UK commercial policies either exclude US exposure or provide only limited cover for it. If you sell into the US market, you should discuss this specifically with your broker to ensure your policy responds adequately.
