How Brick Manufacturing Plants Are Insured in the UK

Introduction

Brick manufacturing is a high-heat, high-capital, high-compliance operation. You’ve got kilns running at extreme temperatures, heavy plant and conveyors moving raw materials, dust and silica exposure, forklifts and HGV movements, and a site that often includes large yards, bunded fuel tanks and substantial stock. In the UK, insurers look at brick plants as a blend of manufacturing, warehousing and logistics—so the best insurance programmes are built as a tailored package, not a one-size-fits-all policy.

This guide explains how brick manufacturing plants are typically insured in the UK, what cover is usually included, what underwriters focus on, and how to reduce premiums without leaving gaps.

1) The core insurance structure: “Commercial Combined” for manufacturers

Most brick plants are insured under a Commercial Combined policy (sometimes called a “combined” or “package” policy) with several sections bundled together. This is common because the risks are interconnected: a kiln fire can damage buildings and machinery, trigger a shutdown (business interruption), create third-party injury risk (liability), and lead to pollution clean-up.

A typical programme may include:

• Buildings and structures (including kilns, chimneys/stacks, silos, fixed plant)
• Contents and machinery (production lines, mixers, conveyors, dryers, kilns, robotics)
• Stock (raw materials, work-in-progress, finished bricks/pavers)
• Business interruption (BI)
• Employers’ liability (EL)
• Public and products liability (PL/Products)
• Engineering / machinery breakdown
• Goods in transit (if you deliver)
• Environmental impairment / pollution (where exposures justify it)
• Cyber (increasingly relevant for automated plants)

2) Property insurance: what’s insured and how values are set

Buildings, fixed plant and “declared values”

Property cover is the backbone. For brick plants, the tricky part is getting the sums insured right—especially where buildings and fixed plant are specialised.

Insurers will usually want:

• Reinstatement values (not market value)
• Clarity on what’s “building” vs “contents” (kilns and fixed conveyors can sit in either category depending on wording)
• Any tenant vs freeholder responsibilities

Common property perils insured include:

• Fire and explosion
• Storm and flood (site-specific)
• Escape of water (less common but possible in offices/welfare)
• Impact (vehicles, plant)
• Theft and malicious damage (often higher risk in yards)

Fire risk: kilns, dryers, fuel systems and hot works

Underwriters focus heavily on:

• Kiln design, age and maintenance
• Burner systems and fuel type (gas/oil)
• Dust management and housekeeping
• Hot work controls and contractor management
• Fire detection and suppression (including any fixed systems)
• Separation between high-risk areas and storage/office areas

Stock and work-in-progress

Brick plants often hold large volumes of:

• Clay and additives
• Pallets, packaging and timber dunnage
• Finished bricks in yards

Insurers will ask about:

• Maximum stock at peak season
• How stock is stored (height, spacing, yard security)
• Fire breaks and access for the fire service
• Any single points of accumulation (e.g., one large finished-goods area)

3) Business interruption (BI): the cover that keeps cashflow alive

A major loss at a brick plant is rarely “just” property damage. The bigger hit is often downtime.

BI insurance can cover:

• Loss of gross profit (or increased cost of working)
• Standing charges (wages, rent, finance costs)
• Additional costs to keep trading (temporary plant hire, overtime, alternative production)

Key BI choices for brick manufacturers:

• Indemnity period: often 12–24 months; some plants need longer due to lead times on kilns and specialist machinery.
• Basis of settlement: gross profit vs gross revenue (depends on accounts and how you trade).
• Supplier/customer extensions: if you rely on a single clay supplier, packaging supplier, or a major construction customer.
• Utilities extension: power and gas interruptions can halt production.

A common BI pitfall is underestimating restart time. Rebuilding a kiln area, sourcing parts, recommissioning, and passing safety checks can take far longer than expected.

4) Employers’ liability (EL): legally required and closely underwritten

In the UK, most brick plants must carry Employers’ Liability (typically £10m). Insurers will look at:

• Workforce size and roles (kiln operators, maintenance engineers, forklift drivers)
• Use of contractors and labour-only subcontractors
• Training and supervision
• Accident history and near-miss reporting

Key EL exposures in brick plants

• Respiratory risks (silica dust)
• Manual handling injuries
• Slips/trips in wet or dusty areas
• Moving machinery and guarding
• Forklift and vehicle movements
• Heat stress and burns

Strong risk management and documented procedures can materially improve terms.

5) Public and products liability: site visitors, deliveries and product performance

Public liability (PL)

PL covers injury or property damage to third parties—think visiting drivers, customers, auditors, or members of the public near your site.

Insurers will ask:

• Site access controls and visitor procedures
• Segregation of pedestrians and vehicles
• Yard management and signage
• Any on-site contractors and how they’re controlled

Products liability

Bricks are “simple” products, but claims can still happen:

• Alleged defects leading to cracking/spalling
• Incorrect specification supplied
• Batch issues causing widespread remedial works
• Damage to adjacent materials

Products liability is particularly important if you supply:

• Large construction projects
• Public sector builds
• Export markets (contract terms may be tougher)

Some manufacturers also consider:

• Product recall (more common in food/consumer goods, but can be relevant if a batch must be removed)
• Efficacy/fitness for purpose wording (careful—some policies exclude this)

6) Engineering insurance: machinery breakdown and inspection

Brick plants depend on continuous operation. Engineering (Machinery Breakdown) cover can insure sudden and unforeseen mechanical or electrical failure, often including:

• Motors, gearboxes, conveyors
• Compressors and pumps
• Control panels and drives
• Kiln fans and burners (subject to wording)

It may also include:

• Deterioration of stock (if breakdown ruins work-in-progress)
• Engineering BI (loss of profit caused by breakdown)

Insurers will want to see:

• Preventive maintenance schedules
• Condition monitoring (vibration analysis, thermography)
• Critical spares strategy
• Competent engineers and contractor controls

7) Environmental and pollution risks: when standard policies aren’t enough

Standard liability policies often cover sudden, accidental pollution—but may exclude gradual pollution or clean-up costs.

Brick plants can have exposures from:

• Fuel tanks and bunds
• Oils and hydraulic fluids
• Run-off from yards
• Waste and by-products
• Historic land contamination (depending on site history)

Where exposures are meaningful, consider Environmental Impairment Liability (EIL), which can cover:

• Clean-up costs (on-site and off-site)
• Third-party claims
• Legal defence
• Gradual pollution (if included)

8) Motor and transit: deliveries, fleets and hired-in vehicles

If you operate:

• Company vans
• HGVs
• Forklifts on public roads (rare but possible)

…you’ll need appropriate commercial motor cover.

If you deliver bricks to sites, Goods in Transit can cover:

• Loss or damage in transit
• Loading/unloading incidents (wording varies)

Insurers will ask about:

• Vehicle security and tracking
• Driver age/experience
• Claims history
• Delivery radius and types of sites

9) Cyber and data: modern plants are automated plants

Many brick plants use:

• PLCs and SCADA systems
• Remote monitoring
• ERP and scheduling
• Supplier portals

Cyber insurance can help with:

• Ransomware and business interruption
• Data breach response
• Incident response costs

Even if you don’t hold sensitive consumer data, operational disruption is a real risk.

10) What underwriters typically ask for (and why)

To quote a brick manufacturing plant properly, insurers commonly request:

• Full site description: processes, layout, hours of operation
• Turnover, wage roll, and staffing
• Claims history (usually 3–5 years)
• Sums insured for buildings, plant, stock
• BI figures and indemnity period
• Fire risk details: detection, alarms, extinguishers, hydrants, sprinklers (if any)
• Maintenance and inspection regimes
• HSE documentation: risk assessments, COSHH, training records
• Dust control measures
• Security: fencing, CCTV, lighting, access control
• Flood information: location, previous flooding, resilience measures

The goal is to evidence that you understand your risks and manage them consistently.

11) Common exclusions and gaps to watch

Brick manufacturers should pay close attention to:

• Wear and tear (not covered—use maintenance and engineering cover)
• Gradual pollution (often excluded unless EIL purchased)
• Defective workmanship/design (may be excluded; can affect product claims)
• Heat damage and process-related losses (wording matters)
• Underinsurance and average clauses
• Unspecified suppliers/customers (BI dependency gaps)
• Unoccupied buildings (if parts of site are mothballed)

A broker can often negotiate better wording if the risk is well-presented.

12) Practical steps to improve insurability and reduce premiums

Insurers price brick plants based on loss potential and how controllable the risk is. Practical improvements include:

• Documented preventive maintenance and critical spares
• Strong housekeeping and dust management
• Clear hot work permit system
• Segregated storage for pallets/packaging
• Vehicle/pedestrian separation and yard controls
• Regular fire alarm testing and extinguisher servicing
• Updated reinstatement valuations and stock declarations
• Business continuity planning (alternative production routes, key supplier backups)

Even small operational changes can improve terms at renewal.

FAQs

What is the best type of insurance for a brick manufacturing plant?

Usually a Commercial Combined policy with tailored sections for property, BI, liability and engineering. The “best” programme depends on your process, site layout, and reliance on specialist machinery.

How much employers’ liability cover do UK manufacturers need?

Most UK businesses with employees need EL, typically £10 million. Your insurer will confirm the legal requirement and appropriate limit.

Do brick plants need products liability insurance?

If you manufacture and supply bricks, products liability is strongly recommended. Claims can arise from alleged defects, incorrect specification, or damage caused during installation.

Is machinery breakdown insurance worth it for brick manufacturing?

Often yes. Brick plants rely on continuous production, and breakdowns can be expensive and cause long downtime. Engineering cover can insure sudden failures and may be extended to include engineering BI.

Does property insurance cover kiln fires?

Fire is usually covered, but insurers will scrutinise kiln risk controls and may apply conditions or higher excesses. The exact scope depends on policy wording and risk presentation.

Conclusion: insure the whole operation, not just the buildings

Brick manufacturing insurance in the UK is about protecting the full chain: property, machinery, people, products and cashflow. The strongest programmes combine robust cover with evidence of good risk management—so if something goes wrong, you can repair, restart and keep customers supplied.
