Power Electronics Manufacturing Insurance: A Complete Guide for UK Technology Manufacturers
Power electronics is one of the most dynamic and demanding sectors in UK manufacturing. From inverters and converters to motor drives, rectifiers, and power supply units, the businesses that design and produce these components sit at the heart of modern infrastructure — powering electric vehicles, renewable energy systems, industrial machinery, data centres, and consumer electronics alike.
But with that complexity comes significant risk. A single product fault can cascade into a multi-million pound liability claim. A fire in a production facility can halt output for months. Intellectual property theft or a cyber breach can devastate a business that has invested years in R&D. For power electronics manufacturers operating in the UK, having the right insurance in place is not just good practice — it is a commercial and regulatory necessity.
This guide explores the key insurance products relevant to power electronics and technology manufacturing businesses, the risks unique to the sector, and how Insure24 can help you build a protection package that fits your operation.
Understanding the Power Electronics Manufacturing Sector
Power electronics manufacturing sits at the intersection of electrical engineering, materials science, and software development. UK businesses in this sector produce components and systems including:
- AC/DC and DC/DC converters
- Inverters for solar, wind, and battery energy storage systems
- Variable frequency drives (VFDs) and motor controllers
- Switch-mode power supplies (SMPS)
- Uninterruptible power supplies (UPS)
- Power factor correction (PFC) equipment
- Semiconductor modules and IGBTs
- Electric vehicle (EV) charging infrastructure and on-board chargers
Many UK manufacturers in this space supply components to sectors including automotive, aerospace, defence, healthcare, and utilities — industries where product failure carries serious safety implications and, consequently, significant legal exposure.
The sector is also subject to a growing body of UK and international regulation. The Electrical Equipment (Safety) Regulations 2016, the Electromagnetic Compatibility Regulations 2016, the UK Product Safety Review (a post-Brexit revision of EU frameworks), and emerging requirements around the UK Battery Regulation all place compliance obligations on manufacturers. Failure to meet these standards can result in product recalls, regulatory fines, and civil litigation — all scenarios where robust insurance is critical.
The Key Risks Facing Power Electronics Manufacturers
Before exploring the insurance solutions, it is worth understanding the risk landscape in detail. Power electronics manufacturers face a combination of operational, product, financial, and reputational risks that differ from many other manufacturing sectors.
1. Product Failure and Liability
Power electronics components operate in high-stress environments — managing significant voltages and currents, often in safety-critical applications. A converter that malfunctions in an EV charging system, an inverter that fails in a hospital's UPS, or a motor drive that causes a production line to stop unexpectedly can result in serious injury, property damage, or financial loss to the end customer.
Under the Consumer Protection Act 1987 and general tort law, UK manufacturers can be held liable for defective products even if they were not negligent — the burden of proof lies with the claimant to show the product was defective. The costs of defending such claims, funding recalls, and settling compensation can be substantial.
2. Fire and Explosion Risk
Manufacturing environments involving high-voltage components, capacitors, and battery-adjacent technologies carry an elevated fire risk. Thermal runaway in lithium-based components, arc flash incidents during testing, and chemical storage risks all contribute to a fire and explosion exposure that is more pronounced than in general manufacturing. A serious fire can destroy machinery, stock, tooling, and finished goods — and the resulting business interruption can outlast even the most substantial property claim.
3. Business Interruption
Power electronics manufacturing often involves long lead times for specialist components, bespoke tooling, and highly trained technical staff. If a key piece of production equipment is damaged or a supplier fails, returning to full output can take months. Business interruption insurance — often underestimated by manufacturers — is designed to cover the ongoing costs and lost gross profit during this period. Getting the indemnity period right is crucial; many manufacturers underinsure here, choosing 12 months when their realistic recovery period is closer to 24 or 36 months.
4. Intellectual Property and Technology Risk
Power electronics design is IP-intensive. Firmware, circuit topologies, control algorithms, and proprietary manufacturing processes represent enormous investment. The risk of IP theft — whether by a disgruntled employee, a competitor, or a foreign state actor — is real and growing. While insurance cannot prevent IP theft, it can cover the cost of legal action to enforce your rights, crisis management, and in some cases, the commercial losses that follow.
5. Cyber Risk
Modern power electronics manufacturers are increasingly reliant on connected manufacturing systems, ERP platforms, and cloud-based design tools. Cyber attacks — including ransomware, phishing, and industrial espionage — are a growing threat to UK manufacturers of all sizes. The consequences of a successful attack include operational downtime, data breaches, and reputational damage. The National Cyber Security Centre (NCSC) has consistently identified UK manufacturing as a priority target sector for threat actors.
6. Supply Chain Disruption
The global semiconductor shortage exposed the fragility of electronics manufacturing supply chains. Power electronics businesses that rely on specialist semiconductors, rare earth materials, or single-source component suppliers face the risk of production halts that are entirely outside their control. Contingent business interruption cover — which extends protection to disruptions caused by named or unnamed suppliers — is worth serious consideration.
7. Employers' Liability and Workplace Safety
Manufacturing environments carry inherent risks for employees — from manual handling injuries and slip hazards to exposure to high voltages during testing and assembly. Employers' liability insurance is a legal requirement for any UK business with employees. But beyond the legal minimum, the cost of defending claims and funding compensation for serious workplace injuries makes adequate cover a financial priority.
Essential Insurance Cover for Power Electronics Manufacturers
Commercial Combined Insurance
For most manufacturing businesses, a commercial combined policy forms the backbone of their insurance programme. It brings together a range of cover types into a single policy, typically including:
- Buildings and Contents: Cover for your manufacturing premises, including the fabric of the building, fixed plant, and machinery.
- Stock and Finished Goods: Cover for raw materials, work in progress, and completed products held on site.
- Machinery and Electronic Equipment: Cover for production equipment, testing rigs, laboratory equipment, and specialist tooling — often the most valuable assets a manufacturer holds.
- Business Interruption: Cover for ongoing costs and lost gross profit following an insured event such as a fire or flood.
- Goods in Transit: Cover for stock and components while being transported to customers or between sites.
- Public Liability: Cover for claims from third parties for injury or property damage arising from your business operations.
- Employers' Liability: Legally required cover for claims from employees who suffer injury or illness as a result of their work.
For power electronics manufacturers, it is important that machinery and equipment is valued accurately and that the business interruption sum insured — and the indemnity period — reflects the true cost and complexity of your recovery scenario. Under-declaration at the point of a claim can lead to significant shortfalls.
Product Liability Insurance
Product liability insurance is arguably the most critical cover for any manufacturer. It protects your business against claims arising from products you have manufactured, supplied, or designed — including products that have already left your premises.
For power electronics manufacturers, the exposure is elevated by the nature of the components and where they end up. A defective power supply in a medical device, a faulty inverter in a solar installation, or a malfunctioning drive in a production-critical system can lead to claims involving personal injury, property damage, and significant consequential losses.
Key considerations for power electronics businesses include:
- Jurisdiction: If you export to the EU, USA, or other markets, ensure your policy extends to cover claims brought in those jurisdictions.
- Retroactive cover: Product claims often arise years after manufacture. Ensure your policy covers products made prior to the inception date where possible.
- Recall costs: Some product liability policies include a product recall extension, or this can be added separately — an important consideration if you supply components at volume.
- Limit of indemnity: Given the high-value end applications of power electronics components, limits of £5m, £10m, or higher are not uncommon and should be considered carefully.
Professional Indemnity Insurance
If your business provides design services, consultancy, or technical specifications alongside your manufactured products, professional indemnity (PI) insurance is essential. PI cover protects you against claims that your professional advice, design work, or technical documentation was negligent — and caused a financial loss to your client.
This is particularly relevant for power electronics businesses that:
- Design bespoke systems or components to customer specification
- Provide application engineering support and technical guidance
- Offer system integration or commissioning services
- Produce technical documentation, safety data, or certification support
A design error that causes a product to underperform, fail to meet regulatory requirements, or cause damage in the field can result in claims for the full cost of recall, redesign, re-testing, and consequential loss — all of which fall within the scope of a well-structured PI policy.
Cyber Insurance
Cyber insurance for manufacturers covers a range of scenarios that have become increasingly common in the UK:
- Ransomware attacks: Cover for the cost of incident response, system restoration, and ransom payment (where legally permissible) following a ransomware infection that locks your systems or production network.
- Data breach response: Cover for the legal, regulatory, and notification costs associated with a breach of personal data — relevant where you hold employee, customer, or supplier data.
- Business interruption: Cover for lost revenue and extra costs incurred while your systems are offline following a cyber event.
- Cyber liability: Cover for third-party claims arising from a breach — for example, if a breach in your systems leads to a client suffering a loss.
The ICO has the power to issue fines of up to £17.5 million or 4% of global annual turnover under the UK GDPR. Even smaller manufacturers hold significant volumes of personal data — employee payroll records, customer contact details, supplier information — and the regulatory and reputational consequences of a breach should not be underestimated.
Engineering and Machinery Insurance
Specialist engineering insurance — sometimes called engineering all risks or machinery breakdown cover — provides protection for the mechanical and electrical breakdown of production machinery and equipment. For power electronics manufacturers, this can include:
- SMT (surface mount technology) assembly lines
- Reflow ovens and wave soldering equipment
- Power testing and burn-in rigs
- Precision CNC equipment for enclosure and heatsink manufacture
- Environmental testing chambers
Machinery breakdown cover fills a gap that many commercial property policies leave open — property insurance generally covers damage caused by an external event (fire, flood, impact), whereas machinery breakdown covers the cost of repair or replacement following an internal mechanical or electrical failure.
Directors and Officers Insurance (D&O)
Directors and officers insurance protects the personal assets of company directors and senior managers in the event they face personal legal action arising from decisions made in their professional capacity. For electronics manufacturers, this includes scenarios such as:
- Regulatory investigations by the HSE, FCA (if financially regulated), or the ICO
- Shareholder or investor disputes
- Employment disputes brought by senior employees
- Allegations of wrongful trading or mismanagement
As power electronics businesses grow — particularly those attracting investment or operating in regulated supply chains such as defence, healthcare, or automotive — D&O cover becomes an increasingly important part of a complete insurance programme.
Regulatory Compliance and Insurance
UK power electronics manufacturers operate under a complex and evolving regulatory framework. Key regulations with direct relevance to insurance and liability include:
- Electrical Equipment (Safety) Regulations 2016: Require that electrical equipment is safe and meets essential safety requirements before being placed on the UK market. Non-compliance can lead to enforcement action and product recall obligations.
- Electromagnetic Compatibility Regulations 2016: Require that electrical and electronic equipment does not cause harmful interference and is itself resilient to electromagnetic disturbance. Relevant for power electronics operating in sensitive environments.
- UK REACH: Controls the use of substances of very high concern (SVHCs) in manufacturing. Relevant for power electronics businesses using certain solvents, coatings, and materials in production.
- UK Battery Regulation (in progress): Forthcoming UK-specific regulation on battery due diligence, recycling, and labelling — relevant for manufacturers producing battery management systems and EV charging equipment.
- UKCA Marking: The UK Conformity Assessed mark, mandatory for products placed on the GB market. Manufacturers must ensure their products meet the relevant technical standards and maintain appropriate technical documentation.
Insurance does not replace compliance — but it provides an essential financial buffer when regulatory processes result in investigation costs, recall expenses, or legal proceedings. A product liability policy that includes regulatory defence costs, and a professional indemnity policy that covers design certification errors, can make a significant difference when a regulatory issue arises.
Sector-Specific Considerations
EV and Renewable Energy Supply Chains
Power electronics manufacturers supplying the EV and renewable energy sectors face some of the most demanding customer contract requirements in UK manufacturing. Tier 1 automotive suppliers and renewable energy developers routinely require evidence of product liability limits of £10m or more, extended retroactive cover, and specific wording around consequential losses. Insurers with experience in the automotive and energy supply chain understand these requirements — a broker who can access this specialist market is invaluable.
Defence and Aerospace
Manufacturers supplying defence and aerospace customers operate under ITAR, UK MoD, and NATO supply chain requirements that have specific insurance implications. In many cases, contracts require minimum levels of cover and specific policy wording. Ensuring your insurance programme is structured to meet contractual requirements — not just your own risk assessment — is critical in this sector.
Medical Device Integration
Power electronics components integrated into medical devices are subject to the UK Medical Devices Regulations 2002 (as amended) and MHRA oversight. The liability exposure for a component failure in a medical context can be substantially higher than in other sectors. If your business knowingly supplies components for medical applications, ensure your product liability policy explicitly extends to this use and that limits are set accordingly.

Frequently Asked Questions
Is product liability insurance a legal requirement for UK electronics manufacturers?
Product liability insurance is not a legal requirement in the UK in the way that employers' liability insurance is. However, it is a commercial near-necessity. Many customer contracts in the electronics and technology manufacturing sector require evidence of product liability cover as a condition of supply. Without it, a single product-related claim could pose an existential threat to the business.
What level of product liability cover do power electronics manufacturers typically need?
This depends significantly on the end applications of your products and the customer contracts you hold. Businesses supplying consumer electronics may be comfortable with £2m–£5m limits. Those supplying automotive, defence, healthcare, or critical infrastructure customers are often required to hold £10m, £25m, or higher limits. A specialist broker will be able to advise on market norms for your sector.
Does standard commercial combined insurance cover machinery breakdown?
Standard commercial combined policies typically cover machinery and equipment for damage caused by an insured peril — fire, flood, impact, and similar events. Mechanical or electrical breakdown without an external cause is generally excluded and requires a separate machinery breakdown or engineering insurance policy.
How is business interruption calculated for manufacturers?
Business interruption insurance for manufacturers is typically based on gross profit — the difference between your turnover and variable costs. The indemnity period (the maximum duration of a claim) is set at policy inception and should reflect the realistic time it would take to return to normal trading following a worst-case event. For power electronics manufacturers with specialist equipment and long lead times, underestimating the indemnity period is a common and costly mistake.
Do I need separate cyber insurance if I have a commercial combined policy?
Some commercial combined policies include limited cyber cover, but this is rarely sufficient for a manufacturing business with significant reliance on connected systems, ERP software, and digital intellectual property. A standalone cyber insurance policy provides far more comprehensive cover — including business interruption following a cyber event, data breach response costs, regulatory defence, and third-party cyber liability.
Can Insure24 help with insurance requirements in customer contracts?
Yes. We regularly help manufacturers review the insurance requirements written into their customer contracts and ensure their policy wording and limits meet those requirements. We can also provide certificates of insurance and policy documentation in the formats required by contract managers and procurement teams.
What is contingent business interruption cover and do electronics manufacturers need it?
Contingent business interruption (CBI) cover extends your business interruption protection to losses caused by disruption at your suppliers or customers — not just damage to your own premises. Given the well-documented fragility of electronics component supply chains, CBI cover is worth serious consideration for power electronics manufacturers dependent on specialist semiconductor suppliers or single-source component providers.
