Insight for Brokers
Specialist support for brokers placing complex warehouse risks
What warehouse insurance covers
and who this page is for
Warehouse insurance refers to the protection of buildings, stock, equipment and operational continuity for storage and distribution risks. This guide is designed for brokers who need clear underwriting expectations, risk detail and claims insight when placing warehouse and storage facility risks.
Unique challenges in warehouse risks
Warehousing risks vary widely because construction, storage methods, fire protection and human factors differ from site to site. A single change in storage type or a new product line can materially shift the hazard level. Stock values usually fluctuate through the year which complicates BI calculations.
Fire severity remains the dominant concern. Plastics are often present in almost all warehouses which elevates combustibility and pushes many risks into a higher hazard group . Fire spread is accelerated in high bay racking and in facilities with limited compartmentation. Automation introduces delays in fire service access and heightens reliance on sprinkler design.
Claims frequency increases when security controls are weak. Theft, disgruntled employee behaviour or poor housekeeping have all contributed to major losses historically. Human behaviour risk is a recognised driver of fire and malicious damage exposure in warehousing.
Lithium batteries and mixed storage raise volatility. Thermal runaway and toxic gas release can overwhelm suppression systems and complicate reinstatement costs. These risks now materially influence pricing, inspection expectations and coverage structure in warehouse placements.
Smart warehouses bring both benefits and underwriting complexity. Automation reduces manual error but adds cyber exposure, system failure risks and business interruption sensitivity. Even a short outage can stall distribution networks and impact third parties downstream in the supply chain.
Our approach to underwriting warehouse risks
We first look at the warehouse type and construction. Building materials, age and fire resistance drive our initial view of severity. We consider plastics loading, racking height, compartmentation and whether specialist storage applies.
We then assess fire protection. This includes sprinkler coverage, maintenance evidence, alarm systems, water supply resilience, and any known impairment history. For automated or robotic sites we review whether sprinkler layouts align with system complexity and whether fire access routes remain viable.
Information required at quote stage includes:
- Full site plans
- Storage type and height
- Stock composition including presence of plastics or lithium batteries
- Security controls and staff protocols
- Maintenance records for fire systems
- BI values with basis of calculation and turnover rate of goods
We assess controls such as CCTV, perimeter security, employee screening and handling procedures for hazardous materials. Good risk management, tested business continuity plans and clean housekeeping records support positive selection.
Red flags include incomplete inspection reports, storage changes without updated fire protection, lack of sprinkler obstruction management, poor staff relations indicators, plus lithium battery storage without dedicated controls or ventilation.

Claims insight
Typical claim triggers include fire from plastics, lithium battery thermal runaway, electrical faults, arson, or security breaches. Severity increases when fire protection is impaired or when stock density accelerates heat release. Failures in sprinkler performance have historically led to total losses in large facilities.
Costs escalate due to toxic smoke contamination, clean up of chemical residues, racking replacement and long lead times for specialist machinery. Reinstatement of automated systems adds significant BI exposure which can exceed the material damage cost.
Prompt information helps the claims process, especially stock reconciliation, CCTV evidence, maintenance logs and BI documentation. Brokers strengthen outcomes by ensuring clients maintain accurate stock valuations, updated inspection reports and clear continuity plans.
Expert insight panel
Key insight
Plastics elevate almost every storage risk. Even where goods are not obviously plastic related they are often boxed or wrapped in plastic which increases combustibility and moves the risk into higher hazard classifications.
Scenario
A large fulfilment centre fire spread rapidly after ignition due to mixed flammable inventory. Fire suppression failed to contain heat build up which resulted in a complete building loss. Rebuild timelines extended beyond a year which demonstrated the sensitivity of BI exposure in fast moving retail supply chains.
High risk indicators checklist
- Plastics in storage over expected thresholds
- Lithium batteries not segregated
- Sprinkler systems lacking independent maintenance certification
- Automated picking systems with no alternative fulfilment options
- Evidence of poor staff relations
- Outdated inspection reports (more than three years old)

FAQ
What information does the underwriter need
Site layout, storage types, stock values, fire protection details, security controls and BI calculations.
What drives warehouse pricing
Combustibility of contents, fire protection, building construction, presence of lithium batteries and BI exposure.
What causes most warehouse claims
Fire from plastics, electrical faults, lithium battery failure, arson or security breaches.
How long does a quotation take
Simple risks can be reviewed quickly once full information is provided. Complex automated facilities may require additional checks.
Do inspection reports help
Yes. Ideally reports should be less than three years old and include construction, storage, fire systems and turnover data.
Are there limits unique to warehouse risks
Limits may apply where lithium batteries, plastics density or automation increase severity.
What details do brokers often miss
Changes in storage configuration, unrecorded increases in stock values and incomplete sprinkler maintenance evidence.
What documentation is needed to bind
Final values, confirmed terms acceptance, risk questionnaires, and any required warranties related to fire protection or hazardous storage.
Summary
Warehouse insurance covers buildings, stock and equipment for storage and distribution risks. Key hazards include plastics combustibility, lithium batteries, automation exposure and business interruption sensitivity.
Aspect assesses these risks by reviewing construction, storage type, fire protection and controls. Brokers gain clear appetite signals, specialist support and strong claims communication.
