Property Insurance for Factories, Warehouses & Equipment: A Practical UK Guide

Introduction

Factories and warehouses are built around one thing: keeping production and fulfilment moving. When a fire, flood, theft, or equipment failure hits, the cost isn’t just the building repairs—it’s downtime, missed orders, contractual penalties, and damaged customer trust.

Property insurance for factories, warehouses and equipment is designed to protect the physical assets your business relies on: buildings, stock, plant and machinery, and the tools that keep operations running. This guide explains what a good policy should include, where businesses get caught out, and how to set the right sums insured.

What is property insurance for factories and warehouses?

Property insurance is cover for physical loss or damage to your premises and business property caused by insured events (often called “perils”). It’s commonly arranged as part of a Commercial Combined policy, but it can also be bought as standalone property cover.

For industrial sites, the policy is usually tailored around:

• Buildings (owned premises)
• Tenants’ improvements (if you lease)
• Contents (office and operational equipment)
• Stock and materials
• Plant, machinery and specialist equipment
• Business interruption (loss of gross profit or revenue following damage)

Who needs it?

If you operate any of the following, property insurance is typically essential:

• Manufacturing facilities (light industrial to heavy engineering)
• Warehouses and distribution centres
• Cold storage and temperature-controlled sites
• Workshops, fabrication units, and assembly lines
• Businesses with high-value machinery, racking, or automated systems
• Firms with significant stock levels or long lead-time components

Even if you lease your unit, you may still be responsible for internal fixtures, racking, stock, and equipment—and you may be contractually required to insure them.

What does it usually cover?

Coverage varies by insurer and wording, but a well-built policy often includes the following sections.

1) Buildings

If you own the premises, buildings cover typically includes:

• The structure (walls, roof, floors)
• Fixed services (electrics, plumbing, heating)
• External features (yards, gates, fences)
• Outbuildings and ancillary structures (where declared)

If you lease, you may need cover for tenants’ improvements such as:

• Partitioning
• Mezzanines
• Installed lighting
• Security systems
• Fixed extraction or ventilation

2) Contents and business equipment

This can include:

• Office furniture and IT
• Forklifts and warehouse handling equipment (depending on use and licensing)
• Tools and portable equipment (often with limits)
• Packaging machinery and labelling systems

3) Plant, machinery and production equipment

Factories often rely on high-value assets with long replacement lead times. Property policies may cover these for insured perils (fire, flood, etc.).

Important: mechanical or electrical breakdown is not always included under standard property cover. For that, you may need Engineering Breakdown (also called machinery breakdown).

4) Stock, raw materials and finished goods

Stock cover can apply to:

• Raw materials
• Work in progress
• Finished goods
• Packaging

You’ll usually need to declare:

• Maximum values at risk
• Storage methods (racking, pallets, floor stacking)
• Any high-theft items
• Whether goods are temperature-controlled

5) Business interruption (BI)

This is often the difference between a painful incident and a business-ending one.

BI can cover:

• Loss of gross profit (or revenue) following insured damage
• Increased cost of working (e.g., temporary premises, overtime, outsourcing)
• Rent and rates (where insured)

Key settings to get right:

• Indemnity period (commonly 12, 18, or 24 months)
• Gross profit calculation (make sure it reflects your accounts)
• Dependencies (key suppliers, key customers, or utilities)

Common insured events (perils)

Typical perils include:

• Fire and smoke
• Explosion
• Storm and flood
• Escape of water (from fixed systems)
• Theft (often with security conditions)
• Impact (e.g., vehicle strike)
• Malicious damage
• Subsidence (sometimes optional and heavily underwritten)

Some policies are written on an “all risks” basis for certain sections (meaning everything is covered unless excluded), but even then, exclusions and conditions matter.

Key exclusions and gaps to watch

This is where many industrial businesses get caught out. Common issues include:

Wear and tear, gradual deterioration, and poor maintenance

Property insurance is for sudden, unexpected damage—not predictable decline. If a roof fails due to years of neglect, insurers may reduce or decline a claim.

Mechanical breakdown (unless added)

If a motor burns out or a gearbox fails without an external insured peril, you may need engineering breakdown cover.

Flood limitations

Flood can be covered, but:

• Some sites have higher excesses
• Some insurers apply sub-limits
• You may need evidence of flood resilience measures

Theft conditions

Theft claims can depend on:

• Minimum security standards (locks, shutters, alarms, CCTV)
• Alarm maintenance and keyholder response
• Evidence of forcible and violent entry

Unoccupied premises

If a warehouse is unoccupied (even temporarily), cover may reduce after a set number of days unless you inform the insurer.

Underinsurance and average

If your sums insured are too low, insurers can apply average, reducing the claim proportionally.

Example: If you insure stock for £500,000 but the true value at risk is £1,000,000, a £200,000 claim could be paid at roughly 50%.

How to set the right sums insured

Getting sums insured right is one of the biggest levers for both claims success and fair pricing.

Buildings: rebuild cost, not market value

Buildings should be insured on a reinstatement basis (the cost to rebuild, including demolition, professional fees, and compliance upgrades).

Tip: Consider a professional rebuild valuation, especially for older industrial buildings or sites with specialist construction.

Stock: peak values, not average

Warehouses often have seasonal peaks. Insure to the maximum value at risk, not the average month.

Plant and machinery: replacement cost and lead times

List:

• High-value machines
• Any bespoke equipment
• Imported machinery with long lead times

If a machine takes 20 weeks to replace, your BI indemnity period and increased cost of working should reflect that reality.

Racking and automation

Racking systems, conveyors, and automated picking can be significant values. Make sure they’re declared correctly—some businesses assume they’re part of the building when they’re not.

Risk factors insurers care about (and how to improve them)

Insurers price industrial property based on both the site and the process. Common underwriting questions include:

• Construction type (steel frame, cladding type, roof materials)
• Fire protection (alarms, sprinklers, extinguishers, hydrants)
• Housekeeping and waste management
• Hot works controls (welding, cutting)
• Storage height and aisle spacing
• Security (alarm grading, CCTV, access control)
• Claims history
• Business continuity planning

Practical steps that often help:

• Keep combustible waste in secure external bins away from the building
• Maintain clear fire breaks and access routes
• Document hot works permits and contractor controls
• Service alarms and suppression systems on schedule
• Improve external lighting and perimeter security

Add-ons worth considering

Depending on your operation, these extensions can be valuable:

• Engineering breakdown (machinery breakdown)
• Deterioration of stock (especially for cold storage)
• Goods in transit (if you move stock between sites)
• Money and theft by employees (where relevant)
• Public and employers’ liability (often packaged in commercial combined)
• Terrorism cover (Pool Re, optional)
• Trace and access (finding leaks or faults)
• Alternative accommodation / temporary premises

Claims: what good looks like

If you ever need to claim, preparation makes a big difference. Best practice includes:

• Keep an up-to-date asset register (including serial numbers)
• Photograph key equipment and storage areas
• Store backups of records off-site or in the cloud
• Maintain inspection and servicing logs
• Record stock levels and valuation method

After an incident:

• Make the site safe
• Notify your broker/insurer promptly
• Document damage with photos and notes
• Keep receipts for emergency spend
• Track downtime and extra costs for BI

How to choose the right policy

When comparing options, look beyond the headline premium. Ask:

• Are buildings, stock, and machinery insured on the right basis?
• What are the key exclusions and security conditions?
• What excess applies for flood, escape of water, and theft?
• Is business interruption included, and is the indemnity period long enough?
• Are there sub-limits for high-value items or racking?
• Does the wording fit your process (manufacturing vs storage vs mixed use)?

A good broker will also help you present the risk well to insurers—clear information often leads to better terms.

FAQs

Is property insurance legally required?

Not usually by law, but it’s often required by lenders, landlords, or contracts with customers. For most factories and warehouses, it’s a practical necessity.

Does property insurance cover equipment breakdown?

Not always. Sudden damage from insured perils may be covered, but internal mechanical or electrical failure often needs engineering breakdown cover.

What if I store goods for other people?

You may need to declare this and consider bailee’s liability and clarity on whether you’re insuring customers’ goods or only your own.

Can I insure multiple sites under one policy?

Yes. Many businesses arrange a combined policy with multiple locations, each with its own sums insured and risk details.

How long should my business interruption indemnity period be?

It depends on rebuild and replacement times. For many industrial risks, 18–24 months is sensible—especially where machinery has long lead times.
