DISASTER RISK INSURANCE THAT HELPS YOU TAKE OFF
Why Natural Hazard Insurance Matters for Semiconductor & Clean Manufacturing
Semiconductor manufacturing is uniquely sensitive to disruption. A general factory may be able to restart after a flood or fire once the building is repaired and machinery is replaced. A wafer fab, cleanroom, packaging/test plant or high-reliability electronics site often faces a longer, more complex recovery: environmental stability must be restored, contamination risk must be controlled, critical utilities must be verified, and equipment and process conditions may require requalification before output returns to normal.
Natural hazards don’t just damage property — they can wipe out throughput, compromise yield, interrupt supply chain commitments and trigger contractual and reputational consequences. The financial impact typically includes: (1) direct repair and replacement, (2) time-element losses from downtime, and (3) the “hidden” costs of recovery such as clean-up, temporary facilities, expediting, overtime, revalidation and urgent logistics.
Insure24 arranges insurance programmes designed around catastrophic risk: flood, storm, fire, smoke, earthquake and other severe events — structured to protect fabs, foundries, OSATs, contract electronics manufacturers and related semiconductor operations across the UK and international supply chains.
What Natural Hazard & Disaster Risk Insurance Typically Covers
Natural hazard protection is normally delivered through a combination of Property Damage, Engineering/Machinery Breakdown, Business Interruption and specialist extensions. The goal is simple: if a major event occurs, the policy should fund the physical rebuild and keep the business financially stable while you restore production.
For semiconductor sites, the most effective programmes are built from the ground up around your facility design, critical utilities, cleanroom strategy, equipment schedule and recovery timeline. We help you map realistic loss scenarios and then structure cover and limits accordingly.
- Property Damage – buildings, cleanrooms, fit-out, plant rooms, offices and warehouses.
- Contents, Plant & Equipment – production tools, test systems, QA labs, MRO equipment and specialist infrastructure.
- Stock & WIP – raw materials, wafers/dies, components, chemicals, finished goods (subject to policy terms).
- Business Interruption – loss of gross profit / revenue during insured downtime (trigger dependent).
- Increased Cost of Working – overtime, temporary outsourcing, hired-in equipment, expedited freight and other recovery costs.
- Engineering/Machinery Breakdown – protection for sudden and unforeseen breakdown that may occur during or after a major event.
- Debris Removal & Professional Fees – clean-up, demolition, architects, engineers and surveyors (subject to sub-limits).
- Alternative Accommodation / Temporary Premises – where arranged and applicable.
- Utilities & Services – cover design aligned to power, chilled water, gas systems and critical services where insurable.
- Supplier/Customer Dependencies – contingent BI options where available and suitable.
Flood Risk: The Fastest Route to Catastrophic Loss
Flooding is one of the most severe threats to high-value manufacturing sites. Water doesn’t need to reach cleanroom levels to cause major disruption: it can damage electrical switchgear, UPS systems, substations, compressors, pumps, chilled water systems, vacuum infrastructure, warehouse stock and key access routes. Even shallow water in plant rooms can translate into extended shutdown due to electrical safety, drying, corrosion risk and equipment replacement lead times.
In semiconductor environments, flood recovery often includes contamination control and clean-up beyond standard industrial restoration. If water impacts HVAC, filtration systems or cleanroom envelope integrity, you may need validation and requalification work to resume stable output. Underwriters therefore focus heavily on flood controls, resilience and historical mapping.
Typical Flood Loss Drivers
- Surface water and intense rainfall overwhelming drainage capacity
- River / tidal flood events impacting industrial estates
- Groundwater ingress affecting basements and ducts
- Water damage to LV/HV switchgear and controls
- Water impact on HVAC, chilled water and air handling
- Stock loss in low-level storage and warehouses
- Access disruption preventing staff and deliveries
- Extended drying and decontamination timelines
Controls That Improve Insurer Confidence
- Flood risk assessment and documented site plan
- Raised critical utilities, switchgear and IT rooms
- Flood barriers, gates, demountable defences and bunding
- Sump pumps with backup power and maintenance logs
- Drainage maintenance and inspection records
- Stock elevation and warehouse zoning protocols
- Emergency response plan and supplier contacts
- Testing of generators/UPS and critical spares strategy
Fire, Smoke and Suppression Events: More Than Just Flames
Fire risk is a top underwriting concern for semiconductor manufacturing because of the concentration of value per square metre and the complexity of recovery. In many incidents, the most damaging factor is not direct flame damage but smoke contamination, corrosive residues, and suppression impacts. Clean agent discharge, sprinkler activation, or water mist systems can be essential for life safety and loss control — but they can still create operational disruption and significant clean-up requirements.
Semiconductor sites often contain hazardous materials, process gases, solvents, and specialised electrical infrastructure. Fire can originate in plant rooms, electrical cabinets, battery storage, reflow ovens, test stations, compressors or maintenance activities. Even small fires can create a full shutdown if critical services are affected or the site must be declared safe before restart.
Common Fire/Smoke Loss Pathways
- Electrical fire affecting switchgear, UPS, battery rooms or substations
- Localised equipment fire with smoke migration to clean areas
- HVAC smoke spread impacting filters, ducting and air quality
- Sprinkler discharge causing water damage and extended drying
- Clean agent release and required inspections/recommissioning
- Corrosive residue affecting sensitive electronics and tools
- Fire brigade activity and associated water ingress or access restrictions
- Temporary shutdown required for investigation and revalidation
Controls Insurers Like to See
- Detection (VESDA where appropriate), alarms and monitored systems
- Sprinklers or suitable suppression systems, inspected and maintained
- Fire compartmentation and smoke control strategies
- Hot works permits and contractor controls
- Electrical inspection/thermography programmes and maintenance logs
- Good housekeeping and segregation of high-hazard areas
- Emergency response drills and clear incident escalation
- Spare parts strategy for critical electrical components
Storm, Wind, Snow and Utility Outage Risk
Storm events can impact buildings and utilities in ways that create disproportionate downtime for semiconductor and electronics manufacturers. Roof damage and water ingress can shut down clean environments. High winds can damage external plant. Snow and ice can disrupt access, deliveries and shift patterns. But the most common storm-related operational hit is utility interruption: power instability, outages, voltage dips, and failures in external services.
Power quality matters in semiconductor manufacturing. Even short interruptions can cause tool faults, loss of process stability, scrap and rework spikes, or lost data in traceability systems. While not all power quality issues are insurable, robust resilience and well-structured time-element cover can reduce the financial severity of a major event.
Storm-Linked Exposures
- Roof damage, leaks and wind-driven rain into clean or production areas
- Damage to external plant: HVAC, chillers, generators, cooling towers
- Flooding from intense rainfall and surface water accumulation
- Power outage or brownout affecting tools, MES and facilities automation
- Telecoms outage impacting remote support and supplier connectivity
- Transport disruption causing missed deliveries and delayed spares
- Extended recovery if critical parts have long lead times
Resilience Measures
- Generators sized for critical loads, with tested run-time and fuel plan
- UPS coverage for sensitive tools and data systems
- Dual feeds or resilience at key substations where feasible
- Preventative maintenance for external plant and weatherproofing
- Spare parts and service agreements for critical utilities
- Weather monitoring and pre-event site checks
- Documented restart procedures and quality verification steps
Earthquake (Quake) and Catastrophe: UK & Global Considerations
Earthquake risk is often associated with overseas manufacturing hubs, but it matters for UK businesses too — not only from direct property exposure (generally lower in the UK), but from supply chain dependency. Many UK semiconductor and electronics manufacturers rely on offshore foundries, packaging houses, raw material suppliers, or specialised tool vendors. A quake event in a key region can create a severe shortage of components, long lead-time delays, and a cascading inability to fulfil customer orders.
If you have overseas sites, global customers, or critical suppliers in catastrophe-exposed territories, your insurance strategy should include more than local property cover. We can consider contingent business interruption and supply chain solutions where available, and help you map dependencies so cover is aligned to your real risk.
The more niche your production is — high-reliability, regulated supply chain, unique IP or single-source tooling — the more important it is to plan for catastrophe resilience. Insurance is one component of that plan: it supports financial stability and recovery, but it works best when combined with clear continuity planning.
Direct Catastrophe Exposures
- Structural damage to buildings and sensitive fit-out
- Damage to tools, test systems and precision equipment
- Loss of utilities and access routes
- Aftershock risk and safety inspections delaying restart
- Stock and WIP losses from mechanical disturbance or environmental instability
Supply Chain Catastrophe Exposures
- Supplier outage for single-source wafers, substrates or components
- Tool vendor disruption and inability to obtain parts or service
- Logistics disruption, port closures and cargo backlogs
- Customer demand volatility and contract pressure
- Extended delivery lead times that outlast “standard” BI indemnity periods
How Disaster Claims Work in Real Life (And Where Businesses Get Caught)
In a catastrophe, the biggest mistakes are usually not about whether you have a policy — they are about whether the policy is structured correctly for your recovery timeline. A semiconductor facility might have large declared values for buildings and equipment, but still face a major gap if the business interruption indemnity period is too short, if limits don’t reflect worst-case downtime, or if key extensions (such as additional increased cost of working, debris removal, specialist decontamination or professional fees) are inadequate.
Another common issue is misunderstanding triggers. Business interruption typically requires insured physical damage (unless you have specialist non-damage BI extensions). A severe external event that causes supply chain disruption, utility interruption or access issues may not automatically trigger cover unless the wording is aligned to those exposures. We help you understand these mechanics before you need them, and we build the programme around scenarios that matter to your business.
The goal is not just to “have insurance” but to have a programme that keeps the business stable under extreme stress: it funds recovery choices, supports cash flow, and enables you to protect customer confidence while you restore output.
What Should Be Declared Properly
- Buildings and fit-out values (including cleanroom envelope and specialist services)
- Equipment schedules and replacement costs (including long lead times)
- Stock and WIP values, including customer-owned goods if applicable
- Gross profit / revenue figures used for BI calculations
- Realistic maximum downtime and recovery timeline assumptions
Coverage Areas That Need Attention
- Indemnity period length (often the most critical BI decision)
- Increased cost of working and extra expense capacity
- Utility dependency and service interruption wording
- Contingent BI for key suppliers/customers (where available)
- Specialist decontamination and restoration requirements
Catastrophic events are rare — but when they happen, the difference is how quickly you can recover. We focus on structuring cover around real-world downtime and restoration.

FREQUENTLY ASKED QUESTIONS
+-
What does natural hazard and disaster risk insurance cover?
It usually combines property damage cover (buildings, contents, plant and equipment) with business interruption and recovery costs following insured events such as flood, fire, storm and other catastrophes. Extensions can include debris removal, professional fees, increased cost of working and (where arranged) certain utility or supply chain dependencies, subject to policy terms and underwriting.
+-
Will business interruption cover losses after a flood or fire?
Typically, business interruption responds when there is insured physical damage that causes downtime, subject to the policy’s wording, waiting periods and indemnity period. Selecting the right indemnity period is critical for semiconductor sites where requalification and restoration can take longer than in general manufacturing.
+-
Does the policy cover cleanroom contamination after a disaster?
Some costs may be captured within property damage, debris removal and reinstatement following an insured event, but “contamination” wording varies significantly. For clean manufacturing, it’s important to structure cover around realistic restoration steps, revalidation requirements and agreed claim triggers, rather than assuming all contamination-related costs are automatically covered.
+-
How do insurers assess flood risk for manufacturing sites?
Insurers commonly consider location risk (including flood mapping), historical flooding, building construction, drainage, the elevation of critical utilities, flood defences, maintenance records, and emergency planning. Demonstrating documented controls (barriers, raised switchgear, pumps, response plans) can improve insurer confidence and terms.
+-
Can insurance cover power outages and utility failures?
Standard business interruption usually requires insured physical damage. Some policies can include service interruption or utility dependency extensions, but availability and triggers vary. The best approach is to review your utility resilience and then structure cover around what is insurable, with realistic waiting periods and limits.
+-
What is contingent business interruption (CBI) and do we need it?
Contingent business interruption can provide protection for loss resulting from damage at specified suppliers or customers (depending on the wording), subject to underwriting and policy terms. It can be useful for semiconductor businesses with single-source suppliers, specialist tool vendors, or critical outsourced processes.
+-
What information do you need to quote disaster risk insurance?
We typically need: site address(es), building construction and protections, equipment schedules and values, cleanroom details (if applicable), stock/WIP values, turnover and gross profit, business interruption indemnity period requirements, utility resilience (UPS/generators), claims history, and details of flood/fire/storm controls and continuity planning.
