Radar System Manufacturing Insurance (UK): A Practical Guide to Cover, Risks & Costs

Introduction

Radar system manufacturing sits right at the intersection of advanced electronics, RF engineering, software, and safety-critical performance. Whether you build radar modules, complete systems, antennas, radomes, power amplifiers, signal processors, or integrated surveillance solutions, you’re dealing with high-value components, tight tolerances, specialist test equipment, and customers who expect reliability.

That mix creates a very specific insurance profile. A single faulty batch of PCBs, a calibration error, a software update that degrades performance, or a supplier issue that introduces counterfeit components can trigger expensive claims, contract disputes, and reputational damage.

This guide explains the core risks radar manufacturers face in the UK, the insurance covers that typically matter most, and what underwriters look for when pricing your policy.

What makes radar manufacturing “high risk” from an insurance perspective?

Radar manufacturing isn’t inherently “dangerous” day to day in the way heavy construction can be, but it is high consequence. The products are often:

  • Mission-critical (defence, aviation, maritime, critical infrastructure)
  • Safety-relevant (collision avoidance, air traffic support, perimeter monitoring)
  • Complex (hardware + firmware + software + integration)
  • Expensive to replace (low-volume, high-value builds)
  • Difficult to test fully (edge cases, environmental conditions, interference)

Even if you’re not supplying defence, many radar customers operate in regulated environments and have strict contractual requirements around liability, quality, and continuity.

Typical radar manufacturing activities (and where claims start)

Insurance needs vary depending on what you actually do. Common activities include:

  • Designing and manufacturing radar subsystems (transmit/receive modules, antennas)
  • PCB assembly, conformal coating, and enclosure build
  • Firmware development and software signal processing
  • Calibration, test, and validation (including environmental testing)
  • System integration and commissioning on customer sites
  • Maintenance, repairs, and field upgrades
  • Supplying components to OEMs or integrators

Claims often start with a “small” issue that becomes expensive because of downstream impact:

  • A component tolerance issue causes intermittent failures in the field
  • A calibration process drift leads to incorrect readings
  • A firmware update introduces a bug that reduces detection performance
  • A supplier delivers counterfeit or out-of-spec parts
  • A test rig fault produces false pass results

The core insurance covers radar manufacturers typically need

Below are the covers most radar system manufacturers consider, with practical examples of how they respond.

1) Product liability insurance

What it covers: Injury or property damage caused by your product after it leaves your control.

Radar-relevant examples:

  • A radar unit installed on a vessel fails to detect an obstacle and there’s a collision, leading to third-party property damage claims.
  • A power supply fault causes overheating and a fire in a customer’s equipment rack.

Key points:

  • Product liability is usually part of Public & Products Liability.
  • Underwriters will look closely at your quality control, traceability, and testing.

2) Public liability insurance

What it covers: Injury or property damage to third parties arising from your business activities (not necessarily your product).

Examples:

  • A visitor trips in your facility.
  • An engineer damages a customer’s property during an on-site commissioning visit.

3) Professional indemnity (PI) insurance

What it covers: Claims arising from professional services, design, advice, specification, or errors/omissions.

Why radar manufacturers often need it: If you design, specify, or provide performance assurances, PI can be crucial—especially where losses are financial rather than physical.

Examples:

  • A design error means the system fails acceptance testing, and the customer claims for project delays and rework costs.
  • Your specification advice leads to the wrong radar being selected for an application, causing operational downtime.

Common PI triggers in radar:

  • Performance claims (range, accuracy, false positives/negatives)
  • Integration issues (interfaces, timing, data formats)
  • Documentation errors (installation, maintenance, safety guidance)

4) Product recall / rectification cover (often an extension)

What it covers: Costs to withdraw, repair, or replace products due to a defect—sometimes including notification and logistics.

Why it matters: Radar products may be deployed across multiple sites or platforms. Rectification costs can be significant even if no injury occurs.

Example:

  • A batch of components is found to be out of spec, requiring replacement of units already shipped.

5) Employers’ liability (EL) insurance (UK legal requirement)

If you employ staff, Employers’ Liability is typically required by law (with limited exceptions).

Examples:

  • An employee develops a work-related condition linked to soldering fumes or chemical exposure.
  • A workshop injury occurs while handling heavy equipment.

6) Property insurance (buildings, contents, stock)

What it covers: Damage to your premises and business contents from insured events like fire, flood, theft.

Radar-specific considerations:

  • High-value test equipment (spectrum analysers, anechoic chamber assets, RF test sets)
  • Sensitive stock (components vulnerable to moisture/ESD)
  • Specialist tools and jigs

Underwriter focus:

  • Fire protection, alarms, security, and how you store high-value portable equipment.

7) Business interruption (BI) insurance

What it covers: Loss of gross profit and ongoing costs if you can’t trade due to an insured property event.

Examples:

  • A fire damages your assembly area and you can’t manufacture for 3 months.
  • Flooding knocks out your test lab and delays shipments.

BI is often where radar manufacturers get caught out: lead times are long, contracts are milestone-based, and delays can trigger penalties.

8) Cyber insurance

Radar manufacturing is increasingly digital: CAD files, firmware repositories, remote support, supplier portals, and sometimes connected devices.

What it can cover:

  • Incident response and forensic support
  • Ransomware recovery
  • Business interruption from cyber events
  • Liability and regulatory costs (where applicable)

Examples:

  • Ransomware locks your production scheduling and QA records.
  • A compromised account leads to theft of design files or customer data.

9) Equipment breakdown insurance

What it covers: Sudden mechanical/electrical breakdown of key equipment (often not covered under standard property).

Examples:

  • A critical environmental chamber fails mid-test.
  • A power surge damages RF test equipment.

10) Goods in transit / marine cargo

If you ship high-value radar units or components, transit cover can be essential.

Examples:

  • A shipment is damaged in transit.
  • Theft from a courier depot.

11) Commercial legal expenses

Useful for contract disputes, employment disputes, and debt recovery.

12) Directors’ & officers’ (D&O) liability

More relevant if you’re raising investment, have a board, or supply into higher-risk sectors.

Contractual requirements you’ll commonly see

Radar manufacturers often face contract clauses that drive insurance limits and wording, such as:

  • Minimum Public/Product Liability limits (e.g., £5m/£10m)
  • PI limits aligned to contract value
  • Indemnity clauses for consequential loss (which insurers may restrict)
  • Requirements to name the customer as an additional insured (where appropriate)
  • Flow-down obligations from prime contractors

It’s important to align insurance with the contract—especially around:

  • Design responsibility (PI exposure)
  • Fitness for purpose wording
  • Performance warranties
  • Liquidated damages

Key risk areas underwriters will ask about (and how to answer well)

If you want better terms, you need to show control. Typical questions include:

Quality management and traceability

  • Do you operate ISO 9001 (or equivalent)?
  • Do you have batch/serial traceability for components and finished units?
  • How do you manage non-conformance and corrective actions?

Testing and validation

  • What test stages exist (incoming inspection, in-process, final test)?
  • Do you use automated test scripts and version control?
  • How do you calibrate test equipment and prevent test rig errors?

Supplier management

  • How do you approve suppliers?
  • How do you prevent counterfeit components?
  • What happens if a key supplier fails?

Documentation and change control

  • Are firmware/software releases controlled and auditable?
  • Do you maintain clear installation and maintenance instructions?
  • How do you manage engineering change orders (ECOs)?

Field work and installation

  • Do you do on-site commissioning?
  • Do you subcontract any installation work?
  • What training and RAMS (risk assessments/method statements) do engineers follow?

Cyber and data

  • MFA, backups, patching, endpoint security
  • Segregation between OT/production systems and office IT
  • Incident response plan

Common exclusions and pitfalls to watch for

Insurance is not “one size fits all”. Radar manufacturers should pay attention to:

  • Contractual liability: some contracts push liabilities beyond standard cover.
  • Fitness for purpose: can be problematic; insurers prefer “reasonable skill and care”.
  • Recall vs warranty: warranty work is usually not covered unless you buy specific extensions.
  • Known defects: issues you knew about before policy inception won’t be covered.
  • Cyber exclusions: some liability policies have cyber-related exclusions; coordinate wording.
  • Territory/jurisdiction: exporting to the US/Canada can change pricing and requirements.

How much does radar manufacturing insurance cost?

Premiums vary widely, but pricing is usually driven by:

  • Turnover and split (manufacturing vs design vs installation)
  • Claims history
  • Contract values and required limits n- Export territories (especially US exposure)
  • Product use-case (safety-critical vs industrial monitoring)
  • Quality systems and testing maturity
  • Subcontracting and installation risk

Rather than chasing the cheapest premium, focus on whether the policy matches your real exposures—especially PI and product liability.

Practical steps to reduce risk (and often improve premiums)

Underwriters like evidence. These steps can help you reduce incidents and present better:

  • Maintain documented QC with sign-offs at each stage
  • Implement component traceability down to batch/lot
  • Use counterfeit mitigation (approved vendors, incoming inspection, X-ray where appropriate)
  • Keep calibration certificates and schedules for test equipment
  • Run environmental and burn-in testing appropriate to the application
  • Control firmware/software releases with versioning and rollback plans
  • Create clear installation and maintenance manuals
  • Record and analyse field failures (FRACAS or similar approach)
  • Separate your networks and enforce MFA + offline backups

Choosing the right policy structure

Many radar manufacturers benefit from a package that brings key covers together, for example:

  • Commercial Combined (Property + BI + Liability)
  • Separate PI policy (often with higher limits and tailored wording)
  • Cyber policy
  • Transit cover

The “right” structure depends on your contracts, turnover, and whether you’re supplying as an OEM, subcontractor, or integrator.

Why specialist advice matters for radar manufacturers

Radar manufacturing is niche. A broker who understands advanced manufacturing and technology risks can help you:

  • Align PI wording to your design responsibility
  • Avoid gaps between product liability and PI
  • Handle contract reviews (insurance clauses and indemnities)
  • Set realistic limits based on contract values and worst-case scenarios

Call to action

If you manufacture radar systems or radar components in the UK and want insurance that matches your real-world risks, it’s worth getting a policy reviewed against your contracts, product use-cases, and testing processes.

Speak to a specialist commercial insurance broker, share a summary of what you manufacture, where you ship, and what your contracts require, and you’ll get a clearer view of the right covers and limits—without paying for protection you don’t need.

FAQs: Radar system manufacturing insurance

Is product liability enough on its own?

Often not. If you design or specify performance, Professional Indemnity is commonly needed because many claims are financial (delay, rework, failure to meet spec) rather than injury/property damage.

Do I need PI if I only manufacture to a customer’s design?

If you truly manufacture “build to print” with no design responsibility, PI exposure may be lower. But many manufacturers still provide advice, integration support, or documentation—so PI can still be relevant.

What if we export radar products?

Exporting can affect territory/jurisdiction and required limits. The US in particular can increase product liability exposure and may require different policy terms.

Does insurance cover warranty claims?

Standard liability policies don’t usually cover the cost of simply repairing/replacing your own faulty product as a warranty obligation. Product recall/rectification extensions may help, depending on wording.

Can cyber insurance matter if we don’t store much personal data?

Yes. Cyber isn’t only about personal data—ransomware, IP theft, and operational disruption can be the bigger risk for manufacturers.

What limits should we buy?

It depends on contract requirements, customer type, and worst-case scenarios. Many businesses start with common liability limits (e.g., £5m) and set PI limits based on contract values and potential downstream losses.
