INSURANCE FOR HIGH-VALUE MACHINERY, COMPLEX MANUFACTURING PROCESSES & HIGH-SEVERITY PRODUCT RISKS
Why Heavy Machinery Manufacturing Needs Specialist Insurance
Heavy machinery and industrial equipment manufacturers often face “high severity, low frequency” risks: large and complex assemblies, high-value WIP, critical lifting operations, commissioning and load testing, and downstream failure exposures once equipment enters service. A single incident can combine property damage, injury exposure, contractual penalties, and prolonged business interruption.
Insurers will assess not just what you make, but how you make it: welding and hot works controls, paint/finishing hazards, lifting plans, test procedures, QA traceability, and the contractual terms you accept in OEM and project supply chains.
What Insurance Covers Heavy Machinery Manufacturing Risks?
Most heavy machinery manufacturers require a structured programme combining property, liability and engineering covers. The right design depends on your processes (fabrication, machining, hydraulics, electrical integration, assembly and testing), your end-use (construction, quarrying, lifting, ports, agriculture, energy), and your contractual responsibilities.
Insure24 helps you build cover that is quote-ready for underwriters and aligned to real-world loss scenarios.
- Property (Buildings & Contents) — cover for premises, machinery, tools, jigs, fixtures and office contents for insured perils.
- Stock & WIP — materials, components and high-value work-in-progress (limits and conditions apply).
- Business Interruption — loss of gross profit and increased cost of working following insured damage (indemnity period is critical).
- Public & Products Liability — injury or damage claims arising from operations or products supplied (wording, territory and limits matter).
- Professional Indemnity — design/specification and engineering advice exposures (where applicable; often claims-made).
- Engineering / Machinery Breakdown — sudden and accidental breakdown of key plant (optional; can include inspection requirements).
- Employers’ Liability — required in most UK cases where you employ staff.
- Goods in Transit / Marine Cargo — transport of heavy equipment and components, including project deliveries (policy dependent).
Common Heavy Machinery Manufacturing Loss Scenarios
Underwriters want to see you understand where losses actually occur — in fabrication, lifting, testing, and after delivery. Typical scenarios include:
- Welding / hot works fire — ignition during fabrication, repairs or rework, often involving hidden voids or stored combustibles.
- Paint booth / finishing fire — flammable liquids, extraction failures, overspray build-up or curing oven incidents.
- Lifting incident — dropped load during crane lifts, rigging failure or uncontrolled movement during assembly.
- Load testing failure — structural failure during proof load tests, hydraulic burst, uncontrolled pressure release or injury exposure.
- Electrical integration fault — wiring defects, control panel arcing, commissioning errors and subsequent damage/outage.
- Hydraulic failure — hose rupture or fitting failure leading to fluid spray, fire potential and equipment damage.
- Defect / recall allegation — safety-related product failure triggers third-party claims, withdrawal costs and legal disputes.
- Project delay penalties — insured event causes late delivery, leading to liquidated damages exposure (contract dependent).
Risk Controls That Improve Insurer Appetite
Heavy machinery risks are insurable, but terms depend on how well controls are evidenced. Underwriters typically focus on hot works discipline, fire protection, lifting plans, test procedures and QA traceability.
Examples of “quote-ready” controls
- Hot works permits — enforced PTW, fire watch, segregation, and post-work checks.
- Housekeeping — controlled storage of paints/solvents, dust management, clear escape routes.
- Lifting management — lift plans, competent appointed persons, LOLER compliance, inspection records.
- Testing discipline — documented test procedures, pressure controls, exclusion zones and sign-offs.
- QA & traceability — batch control, weld traceability, NDT evidence, calibration and records retention.
- Fire protection — detection, alarm monitoring, extinguishers, hydrants/sprinklers where appropriate.
- Supplier control — vetting of critical components and documented incoming inspection.
- Contract review — liability caps, warranty wording and consequential loss clauses (where achievable).
Why Heavy Machinery Losses Become Business Interruption Losses
A large machinery loss is rarely “just” a fire claim. Lead times for specialist plant, long fabrication cycles, tooling replacement, testing re-qualification and project timelines can extend downtime significantly. BI cover should be structured with realistic gross profit calculations and adequate indemnity periods.
Indemnity period guidance
Many heavy machinery manufacturers consider 18–24 months where critical equipment, jigs/fixtures or project delivery cycles create longer recovery windows.
How to Get Heavy Machinery Manufacturing Insurance
- 1. Map your operations — fabrication, machining, assembly, hydraulics, electrical integration, testing and commissioning.
- 2. Confirm risk controls — hot works, lifting plans, test procedures, fire protection and QA traceability.
- 3. Set sums insured — buildings, plant, tools, WIP, stock and realistic BI gross profit.
- 4. Review contracts — warranties, liability caps, territories and project penalty exposures.
- 5. Place cover — align wordings and limits, then bind and document for customers/OEMs.
“Our customer required high limits and tight contract wording. Insure24 helped us present our lifting, testing and QA controls properly and secure cover that matched our project risk.”

FREQUENTLY ASKED QUESTIONS
+-
What insurance does a heavy machinery manufacturer need?
Most heavy machinery manufacturers need a combination of property, business interruption, public & products liability and employers’ liability, with optional covers such as professional indemnity (design), engineering breakdown and goods in transit depending on operations and contracts.
+-
Does products liability cover machinery failure after delivery?
Products liability typically responds where your product causes third-party injury or property damage and you are held legally liable, subject to policy wording, territory, limits and exclusions. It does not usually cover the cost to repair or replace your own product.
+-
How do insurers view lifting and load testing risks?
Underwriters typically want evidence of competent lift planning, LOLER compliance, inspection records, exclusion zones and documented test procedures. These controls can materially influence pricing and insurer appetite.
+-
Why is business interruption important for heavy equipment manufacturing?
Recovery times can be long due to specialist plant lead times, tooling replacement, re-qualification and project schedules. BI should be set with realistic gross profit and an adequate indemnity period (often 18–24 months for complex risks).
+-
Can Insure24 help with contract and OEM insurance requirements?
Yes. We regularly help manufacturers align limits, territories, wordings and evidence packs (QA, lifting, testing, fire controls) to meet OEM and project contract requirements and secure workable terms.
+-
How quickly can you arrange heavy machinery manufacturing insurance?
Indicative terms can often be progressed quickly once core information is clear, but complex risks (high values, testing exposures, exports or specialist wordings) can require deeper underwriting. We’ll move it forward efficiently with the right data upfront.
