Employers’ Liability Insurance for Block Factories (UK Legal Requirements)

Introduction

If you run a UK block factory—manufacturing concrete blocks, paving blocks, or similar masonry products—you’ll know the work is hands-on, noisy, dusty, and often involves heavy plant and repetitive manual handling. That combination can create real injury risk for employees, agency staff, apprentices, and even labour-only subcontractors.

Employers’ Liability (EL) Insurance is the core policy designed to protect you if an employee claims they were injured or became ill because of their work for you. In most cases, it’s also a legal requirement in the UK. This guide explains what the law expects, what “good” looks like for a block factory EL policy, and how to reduce the chance of a claim.

What is Employers’ Liability Insurance?

Employers’ Liability Insurance covers your legal liability if an employee (or someone treated as an employee) suffers:

• Injury at work (e.g., crush injuries, slips, falls)
• Work-related illness (e.g., respiratory problems linked to dust exposure)
• Disease that develops over time (e.g., hearing loss)

It typically pays:

• Compensation awarded to the claimant
• Legal defence costs
• Claimant legal costs (where you are liable)

For block factories, EL is often the “anchor” policy that sits alongside Public Liability, Product Liability, Commercial Combined, and (where relevant) Motor/Fleet and Contractors’ Plant.

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

In most cases, yes. The key legal framework is the Employers’ Liability (Compulsory Insurance) Act 1969.

If you employ anyone in the UK, you will usually need EL insurance with a minimum cover level set by law.

The minimum level of cover

Most UK EL policies provide cover of at least £5 million, which is the legal minimum. In practice, many insurers provide £10 million as standard.

Who counts as an “employee” for EL?

This is where block factories can get caught out. “Employee” can include:

• Full-time and part-time staff
• Temporary workers
• Agency staff (depending on contractual arrangements)
• Apprentices and trainees
• Labour-only subcontractors (common in maintenance and shutdown periods)

If you direct the work, control the site, set the hours, or provide equipment, there’s a good chance EL exposure exists.

Common exemptions (and why they may not apply)

Some businesses are exempt in limited circumstances (for example, certain family businesses). However, most trading block factories with staff, plant operators, yard teams, and drivers will not qualify for exemptions.

If you’re unsure, treat EL as compulsory and confirm your exact position with a specialist broker.

What happens if you don’t have Employers’ Liability Insurance?

Not carrying EL when required can lead to:

• Fines (including daily penalties for being uninsured)
• Enforcement action
• Difficulty winning contracts (many customers require proof)
• Serious financial exposure if a claim arises

Even if you believe your workplace is “safe,” EL is about protecting the business when something goes wrong—especially where injuries can be severe.

Proof of insurance: the certificate requirement

If you must have EL, you must also:

• Display your Employers’ Liability certificate where employees can easily access it (digital display is commonly accepted)
• Keep copies available for inspection
• Retain certificates for a period (good practice is to keep them long-term, as some claims arise years later)

For block factories, it’s sensible to store certificates centrally (e.g., in your compliance folder) and ensure HR and site management can access them quickly.

Why block factories are higher-risk for EL claims

Concrete block manufacturing combines industrial hazards with day-to-day production pressure. Typical EL claim drivers include:

1) Moving plant, forklifts, and yard traffic

Yards and loading areas are busy, with forklifts, telehandlers, HGVs, and pallet movement. Common incidents:

• Pedestrian struck by vehicle
• Reversing accidents
• Crush injuries during loading/unloading
• Falls from vehicles or loading bays

2) Manual handling and repetitive strain

Blocks, pallets, moulds, and packaging can mean repetitive lifting and awkward postures. Claims may involve:

• Back injuries
• Shoulder and knee injuries
• Long-term musculoskeletal disorders

3) Dust exposure (including silica)

Cutting, handling aggregates, sweeping, and dry processes can create airborne dust. Poor control can lead to respiratory issues. Even where wet processes reduce dust, housekeeping and maintenance tasks still create exposure.

4) Noise-induced hearing loss

Vibration, mixers, presses, conveyors, and vehicle alarms create sustained noise exposure. Hearing loss claims can be costly and often relate to historical working conditions.

5) Machinery and guarding

Block presses, mixers, conveyors, and automated lines can cause:

• Entanglement injuries
• Crush points and trapping
• Lacerations
• Maintenance-related incidents during isolation failures

6) Slips, trips, and falls

Water, slurry, uneven yard surfaces, trailing hoses, and poor lighting can lead to frequent “minor” incidents that still become claims.

7) Maintenance shutdowns and contractors

During repairs, upgrades, or shutdowns, you may bring in contractors. If they are labour-only or you control their work, EL exposure can still sit with you.

What a good EL policy for a block factory should cover

Not all EL policies are equal. For block factories, focus on the following.

Adequate limit of indemnity

• Aim for £10 million where possible
• Consider higher limits if you have large headcount, multiple sites, or heavy plant exposure

Legal defence costs

Ensure defence costs are included and not eroded by the indemnity limit (policy wording varies).

Inclusion of temporary and agency labour

Confirm the policy definition of “employee” and how it treats:

• Agency workers
• Seasonal labour
• Apprentices
• Labour-only subcontractors

Cover for work-related disease

This is crucial for:

• Dust-related illness
• Hearing loss
• Vibration-related conditions

Territorial limits

Most block factories are UK-based, but check cover if:

• Employees travel to customer sites
• You do installations or on-site demonstrations
• You have staff visiting suppliers or projects abroad

Indemnity to principals

If you work on customer sites, they may require “indemnity to principal” wording.

Contractual liability

EL generally covers your legal liability, but contract terms can create extra obligations. Have your broker review key contracts.

Common exclusions and problem areas to watch

Policies differ, but common issues include:

• Incorrect wage estimates (premium adjustments and disputes)
• Undeclared activities (e.g., on-site installation, construction work, or haulage)
• Poor claims history disclosure
• Lack of risk management evidence after repeated incidents

The goal isn’t to “shop for loopholes”—it’s to make sure your policy matches what you actually do day to day.

How insurers price EL for block factories

Insurers typically look at:

• Total wage roll split by role (production, yard, drivers, office)
• Headcount and use of temporary labour
• Claims history (frequency and severity)
• Health & safety management and training
• Machinery guarding and maintenance controls
• Traffic management and segregation
• Dust and noise control measures
• Multi-site operations and site standards

If you can present clear controls and documentation, you’ll often get better terms.

Practical compliance and risk reduction checklist (block factory focused)

Reducing injuries reduces claims, downtime, and premium pressure. Practical steps include:

Traffic management

• Separate pedestrians and vehicles where possible
• Mark walkways and crossing points
• Use one-way systems and speed limits
• Train and authorise forklift operators
• Maintain reversing alarms, mirrors, and lighting

Manual handling controls

• Use mechanical aids (pallet trucks, vacuum lifters, cranes)
• Rotate tasks to reduce repetitive strain
• Provide manual handling training that matches real tasks
• Review weights, reach distances, and stacking practices

Dust control

• Use local extraction where appropriate
• Wet suppression and safe sweeping methods
• Provide suitable RPE (and face-fit testing where required)
• Keep records of exposure assessments and training

Noise management

• Carry out noise assessments
• Provide hearing protection and enforce use
• Maintain equipment to reduce noise
• Keep health surveillance records where required

Machine safety

• Guarding and interlocks maintained and audited
• Lockout/tagout procedures for maintenance
• Permit-to-work for higher-risk tasks
• Competency checks for maintenance staff

Slips, trips, and housekeeping

• Clean spillages promptly
• Improve drainage and yard surfacing
• Keep routes clear of pallets, bands, and debris
• Adequate lighting for early/late shifts

Documentation and training

• Induction for all staff and temps
• Toolbox talks and refreshers
• Near-miss reporting and corrective actions
• Accident investigation records

These steps also help you demonstrate “reasonable precautions,” which can be important in defending claims.

EL vs Public Liability: what’s the difference?

This is a common point of confusion.

• Employers’ Liability: claims from employees (and similar workers) for injury/illness linked to work.
• Public Liability: claims from third parties (visitors, customers, members of the public) for injury or property damage.

A block factory often needs both. For example, if a visitor trips in the yard, that’s typically Public Liability. If an employee trips, that’s typically Employers’ Liability.

How much does Employers’ Liability Insurance cost for a block factory?

Costs vary widely based on wage roll, claims history, and risk controls. Two factories with similar turnover can pay very different premiums if one has frequent manual handling injuries or poor traffic segregation.

The most practical way to reduce cost is to:

• Ensure wage roll is accurate and correctly split by role
• Present strong health & safety controls
• Keep good records (insurers like evidence)
• Review limits and wordings annually

What information you’ll need to get a quote

To get accurate EL terms, be ready with:

• Total annual wage roll (split by production/yard/drivers/office)
• Headcount and use of agency labour
• Description of manufacturing process and plant
• Site details (yard layout, traffic controls)
• Claims history (typically 3–5 years)
• Risk assessments and training approach
• Any contract work, installation, or off-site activities

When to review your EL cover

Review at least annually, and also when you:

• Add a new production line or new machinery
• Increase headcount or bring in more temps
• Start new activities (e.g., on-site installation, haulage)
• Move premises or expand yard operations
• Experience a serious incident or near miss

FAQs

Do I need EL insurance if I only employ one person?

Usually, yes. If you employ anyone, you’ll typically need EL.

Does EL cover directors?

Often yes if they are working in the business, but it depends on policy definitions and how they’re remunerated. Confirm with your broker.

Are subcontractors covered?

Bona fide subcontractors usually carry their own insurance. Labour-only subcontractors may fall under your EL. The difference matters—check contracts and working arrangements.

Do I need to display the EL certificate?

Yes, if EL is compulsory for you. Digital display is commonly acceptable as long as employees can access it.

What if an employee is injured due to their own mistake?

EL claims often involve shared responsibility. Insurers typically handle the claim if you are legally liable, even if the employee contributed. Good training and documented procedures help.
