Public Liability Insurance for Electrical Manufacturers (UK)

Introduction: why electrical manufacturers face higher public liability risk

If you manufacture electrical goods, you’re dealing with products that can cause real harm when something goes wrong: electric shock, fires, overheating, or damage to expensive equipment. Even when you do everything right, a single allegation can lead to legal costs, compensation claims, and reputational damage.

Public liability insurance (PLI) is designed to protect your business if a member of the public (or another third party) claims they were injured or their property was damaged because of your business activities. For electrical manufacturers, that can include incidents linked to your factory, your deliveries, your site visits, trade shows, and—crucially—your products.

This guide explains what public liability insurance is, how it applies to electrical manufacturing, what it typically covers and excludes, and how to choose the right level of protection.

What is public liability insurance?

Public liability insurance covers your legal liability to third parties for:

• Injury or illness (for example, a visitor is injured on your premises)
• Property damage (for example, you damage a client’s equipment during an installation visit)
• Associated legal defence costs (solicitors, court costs, expert reports), usually included within the policy limit

It’s important to understand what PLI is not. It’s not a catch-all policy for every risk in manufacturing. It doesn’t replace employers’ liability insurance, and it may not fully address product-related risks unless your policy wording includes product liability (often bundled, but not always).

Public liability vs product liability: what’s the difference?

Electrical manufacturers often hear “public liability” used as a shorthand for third-party claims, but there are two related covers:

• Public liability: incidents arising from your operations, premises, and activities (slips, trips, damage during visits, trade stands, deliveries).
• Product liability: claims arising from products you have manufactured, supplied, or sold once they are in the market.

In practice, many UK insurers offer a combined policy that includes both public and product liability. For electrical manufacturers, product liability is usually the bigger exposure—because a defect can affect multiple customers and lead to large claims.

If you supply components to other manufacturers, you may also need to consider how your contracts allocate liability, and whether your cover extends to:

• Products sold under your brand
• Products sold under a client’s brand (OEM/white label)
• Products incorporated into larger systems

Why electrical manufacturers are seen as higher risk

Insurers assess electrical manufacturing risk differently from low-hazard trades because:

• Potential severity is high: fires and serious injury claims can be substantial.
• Defects can scale: one design or batch issue can affect hundreds or thousands of units.
• Supply chain complexity: multiple suppliers, outsourced assembly, and imported components can increase uncertainty.
• Regulatory expectations: compliance failures can trigger enforcement, recalls, and civil claims.

Even if you manufacture low-voltage or “simple” devices, claims can still arise from overheating, short circuits, battery failures, or incorrect instructions.

What public liability insurance can cover for electrical manufacturers

Coverage varies by insurer and wording, but typical areas include:

1) Injury to third parties on your premises

Examples:

• A courier trips over packaging in your loading bay.
• A client visiting for a factory audit is injured by a moving pallet truck.
• A contractor is injured in a non-employment context (note: some situations may fall under other covers depending on status and contract).

2) Property damage caused during your operations

Examples:

• During a site visit to inspect an installation, your employee accidentally damages a customer’s control panel.
• A forklift knocks into a third party’s vehicle in the yard.
• A delivery damages a client’s flooring or stock.

3) Legal defence costs

Even if a claim is exaggerated or unfounded, legal defence can be expensive. Public liability insurance typically covers the cost of defending a claim, subject to policy terms.

4) Product-related third-party injury or property damage (if product liability is included)

Examples:

• A manufactured power supply overheats and causes a small fire in a customer’s premises.
• A wiring fault leads to damage to connected equipment.
• A battery pack fails and causes smoke damage.

For electrical manufacturers, it’s essential to confirm whether product liability is included and whether there are any restrictions for:

• Lithium batteries
• High-voltage products
• Products used in safety-critical environments
• Export territories

Common public/product liability claims in electrical manufacturing

To make this practical, here are typical claim scenarios that can trigger third-party liability:

• Overheating and fire: a component fails under load, causing damage to property.
• Electric shock: alleged inadequate insulation, incorrect wiring, or faulty assembly.
• Incorrect instructions or labelling: misuse caused by unclear manuals, warnings, or installation guides.
• Batch defects: a supplier provides substandard capacitors that fail early.
• Damage during installation support: your engineer advises a configuration that causes equipment damage.
• Trade show incidents: a visitor trips over a cable at your stand.

Even when the root cause is disputed, you may still face legal costs and the time burden of dealing with the claim.

What public liability insurance usually does not cover

Always check policy wording, but common exclusions/limitations include:

• Damage to your own property (that’s usually covered under commercial property insurance)
• Injury to employees (employers’ liability insurance is the main cover)
• Faulty workmanship to your own product (the cost to repair/replace your own defective product may be excluded)
• Product recall costs (often requires separate product recall/contaminated products cover)
• Contractual liability beyond common law (if you agree to unusual indemnities in a contract)
• Professional advice/design errors (may require professional indemnity, especially if you design systems or provide consultancy)
• Known defects or deliberate non-compliance

For electrical manufacturers, two gaps come up a lot:

1. Recall and rectification: liability may cover third-party damage, but not the cost of recalling units.
2. Design responsibility: if you design products or provide technical specifications, you may need professional indemnity in addition to product liability.

How much public liability cover do electrical manufacturers need?

There’s no single “right” limit, but common UK limits include:

• £1 million: sometimes accepted for low-risk operations
• £2 million: common baseline for many SMEs
• £5 million: often requested by larger clients, landlords, or public sector contracts
• £10 million+: sometimes required for higher-risk manufacturing, major supply contracts, or where products are used in critical environments

A practical way to choose a limit is to consider:

• Your largest customer contract requirements
• The maximum potential property damage scenario (for example, damage to a commercial building or high-value machinery)
• Your distribution scale (units sold per year)
• Whether your products are used in environments where a failure could cause severe loss

If you export, check whether your policy covers the territories you sell into, and whether legal costs and claims handling are suitable for those jurisdictions.

What affects the cost of public liability insurance?

Insurers price based on exposure and risk controls. Factors often include:

• Turnover (overall and sometimes split by product line)
• Nature of products (low-voltage consumer goods vs industrial control systems)
• Manufacturing processes (soldering, PCB assembly, high-temperature processes)
• Quality control and testing (incoming inspection, end-of-line testing, burn-in testing)
• Claims history
• Contract terms (indemnities, warranties, limitation of liability)
• Where you sell (UK only vs worldwide)
• Use of subcontractors

If you can demonstrate strong risk management and traceability, that can help underwriting.

Risk management: steps that can reduce claims (and help with underwriting)

Insurers like to see practical controls. For electrical manufacturers, consider:

Quality and traceability

• Batch/serial number tracking
• Supplier approval and audits
• Incoming component testing for critical parts
• Documented change control (engineering change notices)

Testing and compliance

• Appropriate electrical safety testing (for example, insulation resistance, earth continuity where relevant)
• Clear evidence of conformity assessment and technical files
• Routine calibration of test equipment

Instructions, warnings, and packaging

• Clear installation and user instructions
• Appropriate warnings for misuse risks
• Packaging that protects against damage in transit

Premises safety

• Visitor controls and safe walkways
• Good housekeeping in loading areas
• Fire safety measures and maintenance

Contracts and documentation

• Avoid agreeing to unlimited liability where possible
• Keep signed specifications and acceptance criteria
• Maintain records of customer communications and approvals

These steps won’t remove risk, but they can reduce both the likelihood and severity of claims.

Public liability insurance and compliance: what matters in the UK

Electrical manufacturers often need to show they take compliance seriously. While insurance doesn’t replace compliance, strong compliance can reduce the chance of claims.

Depending on your products and market, you may need to consider:

• Product safety obligations and documentation
• Appropriate markings and declarations
• Health and safety duties for your premises and operations

If you manufacture for regulated or safety-critical sectors (for example, medical devices, industrial safety systems, or products used in hazardous environments), you may need specialist advice and insurance tailored to that risk.

What information insurers typically ask for

To get an accurate quote, expect questions such as:

• What do you manufacture (and what are the highest-risk items)?
• What is your annual turnover and expected growth?
• Where do you sell (UK/EU/worldwide)?
• Do you import components or finished goods?
• Do you design products in-house?
• What testing and quality controls do you have?
• Have you had any claims or incidents?
• What limits do your customers require?

Being prepared with clear answers can speed up underwriting and help avoid cover gaps.

Choosing the right policy: a quick checklist

Before you buy or renew, check:

• Does the policy include product liability as well as public liability?
• Are your products and activities correctly described?
• Are territories and jurisdictions correct for where you sell?
• Are there any exclusions for specific components (for example, batteries) or uses?
• Are defence costs included, and are they inside or outside the limit?
• Do you need add-ons like product recall, professional indemnity, or cyber insurance?

If you’re unsure, it’s better to clarify before a claim happens.

FAQs: Public Liability Insurance for Electrical Manufacturers

Is public liability insurance a legal requirement for electrical manufacturers?

Public liability insurance is not usually a legal requirement in the UK. However, many customers, landlords, and contracts require it. Employers’ liability insurance is a legal requirement if you employ staff.

Do I need product liability insurance as well?

In most cases, yes. If you manufacture, supply, or sell electrical products, product liability is typically essential because claims often arise after the product is in use.

Will public liability cover the cost of replacing faulty products?

Often, no. Many policies cover third-party injury or property damage, but not the cost to repair or replace your own defective products. Ask about “rectification” or “recall” cover if this is a concern.

What limit of indemnity should I choose?

Common limits are £2m, £5m, or £10m. The right limit depends on your contracts, where your products are used, and the worst-case property damage scenario.

Does it cover work at customer sites or trade shows?

Usually yes, as long as your activities are disclosed and included in the business description. Trade shows, demonstrations, and site visits should be mentioned to your broker/insurer.

Does it cover exports?

Some policies cover UK only; others include EU or worldwide. If you export, confirm territories and whether the policy covers claims brought in those jurisdictions.

What if a supplier’s component caused the defect?

You may still face a claim from your customer. Your insurer may then pursue recovery from the supplier (depending on circumstances). Strong supplier contracts and traceability help.

Can insurers exclude certain products?

Yes. Some insurers restrict cover for higher-risk items or specific components. Always ensure your key product lines are declared.

How quickly can I get cover in place?

In many cases, cover can be arranged quickly once underwriting information is provided. More complex manufacturing risks may take longer if insurers need detailed product and compliance information.
