Insurance for Automotive Precision Engineering Manufacturers
Automotive supply chains demand precision, reliability, traceability, and contractual performance. If you manufacture precision components for vehicle platforms, drivetrains, braking systems, steering assemblies, electronics housings, battery systems, or safety-critical parts, your risk profile is not the same as a general engineering workshop.
Even a small dimensional error can lead to a batch rejection, production line stoppage, or costly rework programme. For some components, a defect may not be discovered until the part is installed — potentially triggering product liability claims, recall costs, or disputes under supply agreements.
Insure24 arranges specialist Automotive Precision Components Manufacturing Insurance for UK precision engineering businesses. We tailor cover around your processes, premises, machinery, quality systems and contracts — helping you protect the balance sheet and maintain supply chain confidence.

Why Automotive Precision Manufacturing Insurance Is Specialist
Precision engineering for automotive clients introduces exposures that can materially increase claim severity and contractual fallout. Insurers will look closely at the potential for high-cost losses, including catastrophic fire at a facility, major machinery breakdown, high-value stock damage, and product-related claims affecting vehicle safety or production continuity.
Common premium drivers for automotive precision manufacturers include:
- High-value CNC machinery and dependence on a small number of critical machines
- Quality and traceability requirements, including batch control and inspection records
- Contractual liability provisions and customer-specific insurance requirements
- Potential for line stoppage and consequential losses (even if not always insurable)
- Global supply chain exposure and export territories
- Fire risk from machining oils, coolant systems, swarf and extraction
- High-precision tolerances increasing rework and scrap cost risk
The right insurance programme should address these exposures with appropriate cover sections, realistic limits, and careful policy wording — rather than relying on generic “manufacturing insurance” that may not reflect automotive supply chain risk.

CNC Machinery, Breakdown & Business Interruption
CNC machine tools are often the single most valuable asset category for precision engineering businesses. A serious breakdown can stop production immediately. Where you supply automotive customers with tight delivery schedules, the financial impact of downtime can be significant.
Insurance can be structured to include:
- Machinery breakdown – sudden and unforeseen mechanical/electrical failure (subject to policy terms)
- Business interruption – loss of gross profit and increased costs of working following insured events
- Additional costs – overtime, temporary hire, subcontracting or alternative production (where covered)
Because breakdown cover varies widely, it’s crucial that the policy wording fits your machine profile (spindles, drives, control systems, coolant systems, extraction and automation) and your maintenance regime.
Quality Control, Traceability & Batch Risk
Automotive supply chains are built on quality systems and traceability. Insurers typically view strong quality controls as a key factor in reducing product liability exposure and limiting the severity of batch issues.
Risk controls that can support better insurance terms include:
- Incoming material inspection and supplier approval processes
- In-process inspection and documented sign-off
- Batch and serial number traceability (including heat/lot traceability where relevant)
- Final inspection and metrology records
- Non-conformance reporting and corrective action systems
- Controlled storage and handling to prevent damage, corrosion or contamination
If your business holds certifications or customer approvals, these should be highlighted during underwriting — along with how the systems work in practice.
Products Liability & Automotive Supply Chain Exposure
Products liability is vital for automotive component manufacturers. Claims can arise if a part fails, causes damage, or is alleged to be defective after leaving your premises. Depending on the component, the potential severity can range from property damage to safety-critical incidents.
Insurance should be structured to reflect:
- Nature of components and whether they are safety-critical
- Territories supplied (UK-only, EU, worldwide)
- End-use and whether parts go into vehicles, plant, or related systems
- Contractual requirements and vendor insurance clauses
Some automotive contracts also raise questions around recall costs, consequential loss, and line stoppage. While not all of these losses are insurable under standard liability policies, correct structuring helps avoid gaps and ensures you’re not relying on assumptions at claim time.
Contractual Risk, Delivery Obligations & On-Site Work
Automotive supply agreements may include strict terms around delivery performance, quality, warranties, indemnities and dispute processes. If your business provides any on-site work (installation of tooling, commissioning of fixtures, calibration support, or technical service), you may need insurance that extends beyond standard premises-based cover.
Depending on your activities, optional covers may include:
- Professional indemnity – if you provide design/specification, drawings or technical advice
- Contract works / installation risk – if you install or commission equipment on client sites
- Goods in transit – cover for parts and tools while being transported
The most effective approach is to align insurance structure with how you deliver contracts — rather than trying to force a generic policy to fit.
Risk Management That Can Reduce Premiums
- Fire controls – housekeeping, coolant/oil management, extraction maintenance, alarm testing
- Machinery maintenance logs – planned preventative maintenance and critical spares strategy
- Security – monitored alarms, CCTV, secure stores for high-value tooling/components
- Quality evidence – inspection records, traceability, non-conformance and corrective action
- Business continuity – alternative machining options, subcontracting, realistic BI indemnity periods
- Contract review – clarity on liabilities, reasonable limitation of liability where possible

FREQUENTLY ASKED QUESTIONS
What does automotive precision manufacturing insurance typically cover?
It is typically a tailored package including property and contents, CNC machinery, stock and work-in-progress, business interruption, employers’ liability, and public/product liability. Optional covers may include machinery breakdown, professional indemnity and goods in transit, depending on your activities.
Do I need product liability if I supply parts to Tier 1 or Tier 2 suppliers?
Yes. If you supply manufactured components that are installed or used by others, product liability is strongly recommended to help protect against claims for injury or property damage arising from alleged defects, subject to policy terms.
Can insurance cover rejected batches or rework costs?
Standard insurance typically covers sudden, insured events (like fire or certain breakdown scenarios) rather than general quality disputes or rework. However, the right mix of covers and risk controls can reduce exposure and support better terms.
Does machinery breakdown insurance cover CNC control systems?
It can, depending on policy wording and underwriting. It’s important to disclose machine types, ages, maintenance and any automation/control systems so cover can be arranged appropriately.
Do insurers require evidence of maintenance and quality systems?
Often, yes. Preventative maintenance logs, inspection records and traceability processes can improve underwriting outcomes and may help secure more competitive terms.
Can you insure export territories?
Yes. Cover can often be structured for UK-only, EU or worldwide sales, including products liability and goods in transit options, subject to insurer acceptance and the territories involved.
Do I need professional indemnity as a precision manufacturer?
If you provide design, drawings, specifications, tolerances, or technical advice (rather than purely manufacturing to a customer’s design), professional indemnity may be required and can help protect against claims for financial loss.
How do I choose the right business interruption indemnity period?
Consider how long it would realistically take to repair or replace key CNC equipment, restore production capacity and meet customer lead times. Many manufacturers choose 12–24 months, depending on machine lead times and complexity.
Is theft of metals and tools a common issue?
It can be. Insurers will look at security measures such as alarms, CCTV, perimeter controls and secure storage for tooling, high-value metals and finished components.
How quickly can I get a quote?
Many precision engineering risks can be quoted quickly depending on complexity, values and activities. More complex operations or higher limits may require additional underwriting information.
