What Insurance Is Legally Required for Electrical Manufacturers in the UK?

Introduction

If you manufacture electrical products in the UK—anything from control panels and power supplies to consumer electronics—insurance isn’t just a “nice to have”. In a few key areas, it’s a legal requirement. In others, it’s not technically mandatory, but operating without it can put your contracts, cashflow, and even your ability to trade at risk.

This guide breaks down what insurance is legally required for UK electrical manufacturers, what’s commonly required by customers and landlords, and what cover you should strongly consider because of the real-world risks in electrical manufacturing.

The short answer: the main legal requirements

For most UK electrical manufacturers, the only insurance that is clearly required by law in day-to-day operations is:

• Employers’ Liability (EL) insurance (if you employ staff)
• Motor insurance (if you use vehicles on public roads)

Everything else—Public Liability, Product Liability, Product Recall, Professional Indemnity, Cyber, Property, Business Interruption—may not be legally required in every case, but can be essential depending on what you make, how you sell it, and what your contracts demand.

1) Employers’ Liability insurance (legally required in most cases)

When it’s required

If you employ anyone—full-time, part-time, temporary, apprentices, or labour-only subcontractors—you will usually need Employers’ Liability insurance.

This cover protects you if an employee becomes ill or injured because of their work and makes a claim against the business.

Why it matters for electrical manufacturers

Electrical manufacturing has a mix of risks that can lead to injury or long-tail health claims, including:

• Manual handling injuries (lifting reels, enclosures, tooling)
• Machinery and workshop injuries (presses, cutters, CNC, soldering stations)
• Burns and fumes (soldering, conformal coating, adhesives)
• Electrical testing hazards
• Noise and vibration exposure
• Slips, trips, and falls in production areas

Typical legal expectations

Employers’ Liability is commonly expected at £5 million minimum, and many businesses purchase £10 million.

You’ll also normally need to:

• Display your EL certificate (often digitally is acceptable)
• Keep records and be able to evidence cover

Common “gotchas”

• Directors and family members may still count as employees depending on how the business is set up.
• Labour-only subcontractors can fall under your EL obligations.
• If you have no employees, you may not need EL—but many contracts still ask for it.

2) Motor insurance (legally required if you use vehicles on public roads)

If your business owns, leases, or uses vehicles on public roads, you must have at least the legal minimum motor insurance.

For manufacturers, this often applies to:

• Company vans used for deliveries or collections
• Vehicles used for site visits (installations, commissioning, service calls)
• Staff using their own vehicles for work (which needs the correct “business use”)

Practical tip

If staff use their own cars for work, you should have a clear policy and consider:

• Checking they have business use on their personal policy
• Hired-in / non-owned vehicle cover (where appropriate)

3) Public Liability insurance (not always legally required, but often essential)

Public Liability (PL) is not universally required by law for all manufacturers, but it’s frequently required by:

• Landlords (commercial leases)
• Customers and supply chain contracts
• Trade associations
• Site access rules

It covers injury or property damage claims made by third parties (non-employees), such as visitors, couriers, or members of the public.

Why electrical manufacturers commonly need it

• Visitors in your premises (clients, auditors, contractors)
• Damage caused during delivery/collection
• Accidental damage to a customer’s property during on-site work

4) Product Liability insurance (not always legally required, but highly relevant)

Product Liability covers claims arising from products you manufacture, supply, or import.

Even if it’s not always “legally required” as an insurance policy, electrical manufacturers face product-driven exposures that can be severe:

• Fire caused by a faulty component
• Electric shock injuries
• Damage to other equipment (e.g., control systems, machinery)
• Large batch issues affecting multiple customers

A key point: legal responsibility exists even if insurance isn’t mandatory

Whether or not you buy Product Liability insurance, you can still be legally liable for:

• Injury
• Property damage
• Financial losses (depending on contract terms)

Insurance is how you protect the balance sheet when something goes wrong.

5) Product recall and rectification (often required by contracts)

Electrical manufacturing is one of the sectors where recall and rectification can become a major cost.

This cover can help with costs like:

• Notifying customers
• Shipping and logistics
• Reworking or replacing units
• Disposal of stock
• Crisis management support (depending on policy)

If you supply into regulated or safety-critical environments (industrial controls, medical, automotive, aerospace, energy), recall expectations can be strict.

6) Professional Indemnity (PI) (not legally required, but critical if you design/specify)

If you provide design, specification, consultancy, or advice—such as designing control panels, specifying components, or producing drawings and calculations—Professional Indemnity can be vital.

PI covers claims that your professional work caused a client financial loss.

Where PI commonly applies in electrical manufacturing

• Bespoke design and build
• Design changes requested by clients
• Integration into larger systems
• Documentation errors (drawings, manuals, test reports)

Many B2B customers will ask for PI as part of tender requirements.

7) Property insurance (not legally required, but often required by leases and lenders)

Property insurance covers buildings (if you own them) and contents such as:

• Machinery and plant
• Stock and raw materials
• Tools and equipment
• Office contents

Electrical manufacturers often have high-value, hard-to-replace items (test rigs, calibration equipment, specialist tooling). A single fire, flood, or theft can stop production.

8) Business Interruption (BI) (not legally required, but protects cashflow)

Business Interruption is usually added to a property policy. It helps cover loss of gross profit and ongoing costs if you can’t trade after an insured event.

For manufacturers, BI is often where the real protection sits because:

• Lead times for machinery can be long
• Re-certification and re-validation can delay restart
• Supply chain disruption can extend downtime

9) Cyber insurance (increasingly expected)

Manufacturers are increasingly targeted by cyber incidents, including ransomware and phishing.

Cyber cover can help with:

• Incident response and IT forensics
• Data restoration
• Business interruption from network downtime
• Liability and regulatory costs (where applicable)

If you hold customer data, employee data, or rely on networked production systems, cyber risk is real.

10) Engineering inspection and breakdown (often overlooked)

Depending on your equipment, you may need:

• Engineering inspection (for certain plant and lifting equipment)
• Engineering breakdown cover for sudden mechanical/electrical failure

This is not “insurance required by law” in the same way as EL, but statutory inspections for certain equipment can be mandatory under health and safety rules.

What about legal requirements linked to product compliance?

Electrical manufacturers also have legal duties around product safety and compliance. Insurance doesn’t replace compliance, but it can support you when issues arise.

You may need to consider how you manage:

• Product testing and quality control
• Traceability and batch records
• Technical files and documentation
• Instructions and warnings
• Supplier management for components

If you import products or components, your responsibilities may change. This is one reason Product Liability and recall cover are so commonly requested.

Common contract requirements (even when not “law”)

Even if only EL and motor are strictly legal requirements for many manufacturers, customers and partners often require:

• Public Liability (often £2m–£10m)
• Product Liability (often £2m–£10m, sometimes higher)
• Professional Indemnity (commonly £250k–£5m)
• Cyber (increasingly requested)
• Evidence of cover before onboarding

If you can’t provide certificates, you may lose work.

• Cyber: Recommended if you rely on IT, hold data, or have connected operations
• Engineering inspection/breakdown: Recommended depending on plant and statutory inspections

FAQs

Is Product Liability insurance legally required in the UK?

Not in every situation as a standalone legal requirement, but you can still be legally liable for injury or damage caused by your products. Many contracts also require it.

Do I need Employers’ Liability if I only use subcontractors?

Often yes—especially for labour-only subcontractors. It depends on working arrangements, so it’s worth checking.

What if I’m a small manufacturer working from a unit with no staff?

You may not need Employers’ Liability, but you may still need Public and Product Liability to satisfy landlords and customers, and to protect against claims.

If I import components or finished products, does that change anything?

It can. Importers may take on additional responsibilities in the supply chain. From an insurance perspective, Product Liability and recall considerations become even more important.

Next steps

If you want, tell me:

• What you manufacture (e.g., control panels, consumer devices, power supplies)
• Whether you design as well as build
• Where you sell (UK only, EU, worldwide)
• Your typical contract size and who you supply (end users vs OEMs)

…and I’ll suggest a clean, contract-friendly insurance package and a short “proof of insurance” paragraph you can use in tenders.
