Cold storage projects (refrigerated warehouses, food distribution hubs, pharmaceutical storage, cold rooms in hospitality, and temperature-controlled manufacturing) sit right on the fault line between construction engineering and high-consequence operations. A single failure can trigger:
Rapid stock deterioration (food spoilage, vaccine/biologic temperature excursions)
Business interruption (halted dispatch, rejected deliveries, lost contracts)
Regulatory and contractual exposure (HACCP, BRCGS, MHRA/GDP for pharma, customer audits)
Liability claims (third-party goods, contamination, product recall)
Costly remediation (strip-out, decontamination, re-commissioning, revalidation)
From an insurance perspective, cold storage failure is often a multi-policy event: a mechanical/electrical breakdown can become a property loss, a BI claim, a liability claim, and—during construction—an engineering claim.
Cold storage failures tend to happen at the worst time: late-stage construction, commissioning, or early handover when systems are complex, documentation is incomplete, and responsibility is shared.
Typical triggers:
Compressor failure due to incorrect oil management, contamination, or poor commissioning
Refrigerant leaks (ammonia, CO2, HFC/HFO) from poor brazing, vibration, or valve issues
Incorrect charge levels or control settings
Inadequate redundancy (single point of failure)
Insurance impact: can involve Contractors’ All Risks (CAR)/Erection All Risks (EAR), Machinery Breakdown, and Delay in Start-Up (DSU).
Typical triggers:
Inadequate generator sizing or ATS (automatic transfer switch) faults
Poor segregation of critical circuits
Harmonics/voltage instability damaging drives and controls
Cable terminations overheating
Insurance impact: may trigger property damage and BI, but coverage depends on whether the policy includes utilities failure and whether the event is considered “damage” or “non-damage BI”.
Typical triggers:
Software bugs, misconfigured alarms, sensor calibration errors
Network outages, cyber incidents, or poor change control
Incorrect setpoints leading to freeze/thaw cycles
Insurance impact: can be tricky—some policies treat software/firmware as excluded unless there is resulting physical damage. Cyber may require a Cyber Insurance response.
Typical triggers:
Poor vapour barrier continuity causing condensation and ice build-up
Thermal bridging at penetrations, joints, and fixings
Incorrect panel installation or damaged insulation
Insurance impact: often leads to progressive damage and disputes over whether it’s a defect (excluded) or resulting damage (potentially covered).
Typical triggers:
Incompatible sprinkler design for low temperatures
Incorrect heat tracing, frozen pipework
Fire alarm integration issues with plant shutdown
Insurance impact: can create major property exposures and compliance issues, affecting insurability and premium.
Cold storage losses rarely stop at “fix the plant.” Claims often include:
Rectification costs: repair/replace compressors, evaporators, controls, cabling
Strip-out and reinstatement: removing damaged panels, floors, vapour barriers
Decontamination: mould, bacteria, odour, cleaning chemicals
Stock loss: owned stock and customers’ goods
Business interruption: lost gross profit, extra expenses, alternative storage
Contractual damages: liquidated damages (LDs), penalties, loss of key accounts
Professional liability: design error allegations against engineers/consultants
This is why risk management and insurance should be designed together—especially on projects where the cold chain is mission-critical.
Insurers don’t just price the equipment—they price the probability of failure and the speed of detection/response. Strong controls can reduce both.
Redundancy and resilience: N+1 compressors, dual power feeds, fail-safe controls
Critical spares strategy: lead times for compressors, drives, PLC modules
Thermal modelling: identify thermal bridges and condensation risk
Materials selection: correct insulation type, vapour barrier spec, food-safe finishes
Fire strategy: sprinkler suitability, detection, compartmentation
Quality assurance on refrigeration pipework: pressure testing, leak detection, vibration control
Moisture management: protect insulation and vapour barriers from damage
Hold points and inspections: before closing up walls/ceilings
Commissioning plan: staged start-up, load testing, alarm verification
Integrated systems testing: refrigeration + power + controls + alarms
Temperature mapping and validation: especially for pharma and high-value goods
Alarm escalation procedures: who is called, response times, out-of-hours cover
Maintenance readiness: contracts in place, spares on site, training completed
Remote monitoring with independent alerts (not just BMS)
Emergency response plan: transfer stock, temporary cold storage, logistics partners
Supplier SLAs: guaranteed response times for refrigeration engineers
Cyber hygiene for control networks: segmentation, MFA, patching, backups
Cold storage failure can sit across multiple covers. The right structure depends on whether the risk is during construction, commissioning, or operations.
Best for: physical loss or damage to contract works and onsite materials during the build.
Key considerations:
Testing and commissioning clauses: are they included, and to what extent?
Defects exclusions: many policies exclude the cost of fixing defective parts but may cover resulting damage.
Offsite storage and transit: critical for plant and panels.
Best for: loss of revenue/gross profit due to a covered delay caused by insured physical damage.
Key considerations:
DSU typically requires insured physical damage under CAR/EAR.
Waiting periods and indemnity periods must match realistic commissioning and ramp-up timelines.
Best for: sudden and accidental breakdown of refrigeration plant, electrical systems, and controls.
Key considerations:
Does the definition of “machinery” include controls, drives, PLCs, sensors?
Are refrigerant leaks covered, and are there sub-limits?
Is there cover for expediting expenses (rush parts, overtime)?
Best for: operational sites post-handover.
Key considerations:
BI triggers: many policies require damage; consider extensions for utilities failure.
Ensure gross profit and increased cost of working are adequate.
Consider customers’ goods and stock deterioration extensions.
Best for: stock moving between sites, third-party logistics, and distribution.
Key considerations:
Temperature-controlled transit often needs specific conditions and monitoring.
Claims can hinge on proof of temperature excursion and handling.
Best for: third-party injury/property damage and product-related claims.
Key considerations:
Cold storage failure can lead to contamination allegations.
Contractual liability and recall exposures may need specific wording.
Best for: design and specification errors, negligent advice, and engineering consultancy exposures.
Key considerations:
Ensure PI covers relevant disciplines (mechanical, electrical, controls, fire engineering).
Watch for exclusions around fitness for purpose, contractual warranties, and pollution.
Best for: ransomware, system compromise, and business interruption from cyber events.
Key considerations:
Control systems are increasingly targeted.
Look for cover that includes operational technology (OT) and system failure.
Cold storage projects often involve multiple parties: main contractor, M&E contractor, refrigeration specialist, controls integrator, architect, consultant engineer, and client-side FM.
Common dispute triggers:
Ambiguous responsibility for commissioning and performance testing
Unclear acceptance criteria (temperature pull-down time, stability, recovery)
Documentation gaps (as-builts, O&M manuals, validation records)
Change control failures (late design changes, value engineering)
Risk reduction steps:
Define performance criteria and test protocols in the contract.
Use clear sign-off gates: mechanical completion → pre-commissioning → commissioning → performance testing → handover.
Maintain a single source of truth for changes and approvals.
When a cold storage failure occurs, insurers and loss adjusters typically request:
Incident timeline and alarm logs
Temperature records (including independent monitoring)
Maintenance logs and commissioning reports
Photographs, site reports, and engineer findings
Evidence of stock ownership and value
Disposal certificates (for spoiled stock)
Contracts and SLAs (response times, responsibilities)
Good documentation can be the difference between a smooth settlement and a prolonged dispute.
Use this as a quick internal audit.
Redundancy designed (power + refrigeration)
Independent temperature monitoring and alerting
Commissioning plan includes integrated systems testing
Vapour barrier and insulation QA with hold points
Critical spares identified and lead times confirmed
Emergency stock transfer plan tested
Cyber controls for BMS/PLC network in place
Insurance programme reviewed for DSU/BI/stock deterioration
The “right” insurance depends on:
Project phase (build vs operational)
Stock type (food vs pharma vs industrial)
Contract model (design & build vs traditional)
Reliance on utilities and redundancy
Exposure to third-party goods and contractual penalties
A broker who understands both engineering risk and commercial insurance can align policy wording to the actual failure modes—especially around testing, commissioning, defects, and stock deterioration.
Cold storage failure is rarely caused by one simple fault. It’s usually a chain: design assumptions, installation quality, commissioning gaps, and monitoring weaknesses.
The strongest approach is a combined strategy:
Engineer out single points of failure
Validate performance before handover
Monitor independently and respond fast
Insure the real exposures: plant breakdown, stock deterioration, BI, liability, and (during construction) DSU
If you’re planning a new cold storage build, expanding capacity, or reviewing cover after an incident, it’s worth stress-testing both your engineering controls and your insurance programme—before the next temperature alarm becomes a six-figure loss.
