Employers’ Liability Insurance for Metal & Engineering Firms (UK)

Introduction

Metalworking and engineering businesses keep the UK moving — from fabrication and machining to maintenance, installation, and specialist manufacturing. But these environments also come with higher-than-average injury risks: heavy machinery, hot works, sharp edges, lifting operations, noise, vibration, fumes, and fast-paced production targets.

That’s why Employers’ Liability (EL) Insurance is a core policy for most metal and engineering firms. It’s not just “nice to have” — in most cases it’s a legal requirement. More importantly, it protects your business if an employee (or someone treated like an employee) claims they were injured or made ill due to their work.

This guide explains what EL insurance is, who needs it, what it covers, common claim scenarios in engineering, and practical steps to keep premiums sensible.

What is Employers’ Liability Insurance?

Employers’ Liability Insurance is designed to cover your legal liability if an employee suffers injury, illness, or disease arising out of their employment and then seeks compensation.

In plain terms: if someone working for you says, “I got hurt because of work,” EL insurance can help pay the compensation and the legal costs of defending or settling the claim.

EL is different from Public Liability (which covers injury to members of the public) and Product Liability (which covers injury or damage caused by products you supply). Many engineering businesses need all three.

Is Employers’ Liability Insurance a legal requirement in the UK?

For most businesses that employ staff, yes. UK law generally requires Employers’ Liability Insurance if you employ anyone, including:

• Full-time and part-time employees
• Temporary staff
• Apprentices and trainees
• Labour-only subcontractors (common in engineering and site work)

There are some limited exemptions (for example, some family businesses), but relying on an exemption without proper advice can be risky.

How much cover is required?

The legal minimum is typically £5 million, but most insurers provide £10 million as standard.

Proof and documentation

You’re normally required to display your EL certificate (digital is often acceptable) and keep records. If you’re audited or investigated after an incident, being able to produce the certificate quickly matters.

Why metal and engineering firms face higher EL exposure

Engineering environments can be unforgiving. Even with good safety culture, incidents happen. Common risk drivers include:

• Heavy plant and machinery (CNC, presses, guillotines, lathes)
• Hot works (welding, cutting, grinding)
• Manual handling and lifting operations
• Working at height (installations, maintenance, mezzanines)
• Noise-induced hearing loss
• Hand–arm vibration syndrome (HAVS)
• Exposure to fumes, dust, oils, solvents, and metalworking fluids
• Shift work and fatigue
• Multi-contractor sites and unclear supervision lines

EL claims can be expensive because they often involve long-term injuries, loss of earnings, rehabilitation, and legal costs.

What does Employers’ Liability Insurance typically cover?

While wording varies by insurer, EL policies commonly cover:

• Compensation awarded to employees for injury or illness caused by work
• Claimants’ legal costs (where you’re liable)
• Your legal defence costs (solicitors, experts, court costs)
• Settlements agreed (where appropriate)

Some policies may also include (or offer extensions for):

• Legal advice helplines
• Health & safety support
• Cover for work experience placements
• Worldwide business travel (for employees travelling, not working permanently overseas)

Who counts as an “employee” for EL purposes?

This is where engineering firms can get caught out. EL is not only about PAYE employees.

You may need EL cover for:

• Apprentices and trainees
• Agency staff (depending on contractual arrangements)
• Labour-only subcontractors (where you direct and control the work)
• Casual workers
• Volunteers (in some cases)

If you use subcontract welders, fitters, or maintenance engineers, it’s worth checking whether they are “bona fide” subcontractors (truly independent) or labour-only. The difference can affect both your legal duties and your insurance.

Common EL claim scenarios in metal and engineering

Below are examples of the types of claims insurers see in fabrication, machining, and engineering services.

1) Hand and finger injuries

• Cuts from sheet metal or sharp edges
• Crush injuries from presses or rollers
• Entanglement with rotating machinery

These claims often involve time off work, physiotherapy, and sometimes permanent loss of function.

2) Burns and hot works incidents

• Welding spatter burns
• Contact burns from hot components
• Fire-related injuries during cutting/grinding

Hot works also raise questions about training, PPE, permits, and supervision.

3) Manual handling injuries

• Back and shoulder injuries from lifting stock, tooling, or assemblies
• Strains from awkward handling in tight spaces

Insurers will look for evidence of manual handling assessments, lifting aids, and training.

4) Slips, trips, and falls

• Oil on floors
• Swarf and offcuts
• Poor housekeeping around workstations

These claims can be deceptively costly, especially if fractures occur.

5) Noise-induced hearing loss

Engineering workshops can be loud. Claims may arise years later if hearing protection, monitoring, or controls were insufficient.

6) Vibration-related injury (HAVS)

Use of grinders, sanders, needle guns, and other vibrating tools can lead to HAVS if exposure isn’t managed.

7) Respiratory issues and dermatitis

• Fumes from welding and cutting
• Dust from grinding
• Dermatitis from metalworking fluids and oils

Long-tail occupational disease claims often rely on historical records, which is why documentation matters.

Key exclusions and limitations to watch

EL insurance is broad, but it isn’t unlimited. Common exclusions or limitations may include:

• Deliberate or reckless acts
• Known issues that weren’t disclosed to the insurer
• Certain overseas work arrangements
• Contractual liabilities beyond what the law would impose
• Fines and penalties (insurance typically can’t cover these)

Also watch for:

• Heat work away from premises (some insurers ask specific questions)
• Work at height or use of mobile elevated work platforms (MEWPs)
• Work on rail, airports, or high-hazard sites

If your business has expanded into new activities (e.g., on-site installation, shutdown maintenance, or confined space work), tell your broker/insurer.

How EL insurance is priced for engineering businesses

Insurers usually rate EL premiums using a mix of:

• Payroll (wages) split by trade/occupation
• Claims history (frequency and severity)
• Nature of work (fabrication vs site installation vs maintenance)
• Use of heat, height, lifting equipment, and hazardous processes
• Risk management and safety culture
• Contractual requirements (e.g., principal contractors)

Why accurate wage splits matter

If you have a mix of office staff, CAD/design engineers, shop floor operatives, and site fitters, accurate wage splits can reduce cost. Insurers price higher-risk roles differently.

Practical steps to reduce EL claims (and help premiums)

Good insurance is one part of the picture. Reducing incidents is what really protects your people and your balance sheet.

Consider:

• Documented risk assessments for machinery, hot works, COSHH, manual handling
• Training records (including refreshers)
• PPE issue logs and enforcement (eye protection, gloves, hearing protection)
• Machine guarding checks and lock-off/tag-out procedures
• Housekeeping routines and spill control
• Noise and vibration monitoring, with exposure limits and tool maintenance
• Welding fume controls (LEV extraction, masks where needed)
• Accident/near-miss reporting and follow-up actions
• Contractor management and clear supervision on multi-contractor sites

Insurers like evidence. Keeping records helps you defend claims and can support better terms at renewal.

EL vs Public Liability: do you need both?

Most metal and engineering firms do.

• Employers’ Liability: protects you if employees are injured/ill due to work.
• Public Liability: protects you if a third party (visitor, client, member of public) is injured or their property is damaged.

If you have customers visiting your workshop, deliver/install on client sites, or operate forklifts in shared yards, Public Liability is usually essential.

What limit should you choose?

Many businesses take £10 million as a sensible default because it’s commonly offered and often requested in contracts.

If you:

• Work on large sites
• Supply into high-value industries
• Employ larger teams
• Have higher-risk processes

…you may want to discuss higher limits or broader wording.

What information you’ll need for a quote

To get accurate terms, be ready with:

• Estimated annual wages split by role (office/design/shop floor/site)
• Number of employees, including apprentices
• Details of subcontractors and whether they are labour-only
• Description of processes (welding types, cutting, machining, finishing)
• Any work at height, confined spaces, or hot works away from premises
• Claims history (ideally 3–5 years)
• Health & safety arrangements (risk assessments, training, PPE)

The clearer you are, the fewer surprises later.

FAQs

Do I need Employers’ Liability Insurance if I only have one employee?

In most cases, yes. The legal requirement is about employing staff, not business size.

Does EL cover apprentices and trainees?

Usually yes, but you should declare them and ensure the policy definition of “employee” includes them.

Are subcontractors covered under my EL policy?

It depends. Labour-only subcontractors may be treated like employees. Bona fide subcontractors should normally have their own insurance. If you’re unsure, get advice — this is a common gap.

Does EL cover stress and mental health claims?

Some claims can be made, but outcomes depend on circumstances and evidence. Insurers will look closely at management processes, workload, and documentation.

What happens if I don’t have EL insurance?

You may face enforcement action and fines, and you could be personally exposed to compensation and legal costs.

Next steps

If you run a metal fabrication shop, engineering workshop, or provide on-site installation and maintenance, Employers’ Liability Insurance is one of the most important protections you can put in place.
