Manufacturing insurance: a practical guide for UK makers and engineering firms

Start with the production chain, not just the factory

A manufacturer can be a machine shop, food processor, electronics assembler, fabricator, contract producer or own-brand product business. The insurance picture changes with the materials used, production methods, testing, storage, delivery and the responsibilities accepted under customer contracts. A concise description such as “manufacturing” rarely tells an insurer enough.

Map the operation from purchasing and design through production, quality checks, warehousing and dispatch. Note which work is done in-house, which is outsourced, where products are sold, and whether the business installs or services what it makes. That overview helps identify property, liability, interruption and professional exposures without assuming every policy section is automatically suitable.

Property, machinery and stock values

Buildings insurance should be considered against the cost of reinstatement rather than a property's sale price. Machinery and tooling need their own values and descriptions, particularly when equipment is imported, made to order or slow to replace. Include fixtures, testing equipment, moulds, dies, patterns and plant that may be overlooked in a general contents figure.

Stock can move sharply during the year. Prepare separate estimates for raw materials, components, work in progress and finished products. Include goods held at another site, in transit, at a third-party warehouse or awaiting customer collection where relevant. Explain seasonal peaks and any stock belonging to customers or suppliers so the policy basis can be checked.

Products, contracts and professional responsibility

Product liability may be relevant where an allegation concerns injury or property damage caused by a product. The insurer will need to understand what the business makes or supplies, who uses it, where it is sold and whether it is adapted for particular customers. A product liability section is not automatically the same as product recall insurance; recall costs, triggers, territories and exclusions require separate confirmation.

Design, specification, engineering advice, installation, commissioning and testing can create professional exposures in addition to physical product risks. Review customer terms for warranties, fitness-for-purpose promises, indemnities, liquidated damages and required insurance limits. If the business exports, identify the countries involved and the contractual chain rather than assuming a UK policy applies in every territory.

Business interruption and supplier dependencies

A serious fire or machinery breakdown can stop production even after the damaged item is repaired. Replacement lead times, specialist parts, tooling, approvals, staff availability and customer requalification can all extend recovery. Think about how long it would take to restore normal output and regain contracts, not only how quickly a building could be made usable.

List critical suppliers, utilities, outsourced processes, transport routes and single-source components. Consider whether the policy can address interruption caused by damage at a supplier or customer site, and check any named-supplier restrictions or waiting periods. A plan for temporary production, alternative premises or manual workarounds can help the business explain its resilience.

People, processes and insurance information

Where employers' liability insurance is required, the declared workforce should reflect actual duties and payroll. Insurers may also ask about machine guarding, maintenance, hot work, dust extraction, chemical handling, lifting, contractor access, fire protection and staff training. The point is not to claim that a policy replaces health-and-safety controls; both risk management and accurate insurance disclosure matter.

For renewal, gather recent accounts or turnover splits, payroll, updated property and machinery values, stock peaks, claims information, new products, process changes, contracts, exports, subcontractors and any planned expansion. Tell the broker about changes before they are treated as routine. If the business has several sites, prepare a consistent schedule for each one.

Build a programme around the operation

Manufacturing insurance may involve property, machinery breakdown, business interruption, employers' and public liability, products liability, professional indemnity, cyber, motor and goods-in-transit considerations. Not every business needs every section, and policy names do not guarantee a particular response. Compare the wording, limits, conditions, excesses and exclusions alongside the premium.

The useful first step is a structured conversation about what is made, how it is made and what would stop the business trading. Oak can review the information and seek terms from insurers able to consider the declared risk. Any cover remains subject to insurer acceptance and the final policy wording.

An engineering example: damage, defect and delay are not the same loss

Consider a precision engineering firm that supplies components to a larger manufacturer. Fire damage to its own machine, a claim that a supplied component injured someone, and the cost of replacing an out-of-tolerance batch are three different exposures. Property, products liability and defective-product costs may be treated differently. Design responsibility can add a professional exposure; it should be declared rather than inferred from a products-liability limit.

The firm should also explain how long replacement machinery, recommissioning and customer reapproval could take. A twelve-month interruption period may not suit a recovery process taking longer, but the correct period and financial calculation need discussion. This example illustrates questions to ask, not a promise that a policy will pay.

A practical comparison sheet for quotations

Put each quotation alongside the same schedule of activities, property values, products, territories and limits. Record the excesses, breakdown provisions, product exclusions, recall arrangements, interruption basis and risk-improvement requirements. Resolve missing or ambiguous sections before choosing. A policy can be competitively priced while still excluding the process or product that matters most to the business.
