Fire Insurance for Business:
What Every South African
Business Owner Must Know
Fire is one of the most catastrophic events a business can face. Understanding how your fire cover actually works — before you need it — is one of the most important decisions you can make as a business owner.
What Is Fire Insurance?
Fire insurance is a section within your commercial insurance policy that covers physical loss or damage to your business property caused by fire and a range of related perils. In South Africa, the fire section is a foundational component of almost every commercial short-term insurance policy.
It is important to understand that fire insurance is not a separate product in most cases. It forms part of your broader commercial policy — typically alongside sections covering theft, liability, glass, and money. However, the fire section carries some of the largest potential claim amounts of any section on your policy, which is why understanding it in detail matters so much.
Think of fire insurance as the financial safety net that protects the physical assets your business depends on. Without it, a single fire event could destroy years of investment in buildings, equipment, stock, and fixtures overnight.
"A fire does not give you time to check whether you are underinsured. That conversation has to happen before the flames arrive."
Why Every Business Needs Fire Insurance
South Africa's business environment presents a unique set of fire risks. Load shedding has introduced new ignition dangers through power surges and overloaded electrical systems. Aging infrastructure in many commercial areas increases the likelihood of electrical faults. And the combination of drought conditions and dry vegetation in many provinces creates elevated wildfire exposure for properties on the urban edge.
Beyond the physical risk, there is the financial reality. Most businesses cannot absorb the cost of rebuilding from scratch. A medium-sized retail store in Johannesburg, for example, may have R2 million in fixtures and equipment, R800,000 in stock, and occupy premises with a replacement cost of R4 million or more. Without adequate fire cover, a total loss would be financially unsurvivable for most owners.
Fire insurance also has implications for business continuity. While this article focuses exclusively on the fire section — and not business interruption cover, which is a separate policy section — it is worth noting that protecting your physical assets is the first step in any recovery plan.
What Property Is Normally Covered?
The fire section of a commercial policy typically covers the following categories of business property. Always read your specific policy schedule and wording, as coverage details vary between insurers.
Buildings
Permanent structures including walls, roof, floors, built-in fixtures, plumbing, electrical wiring, and outbuildings. Only covered if you are the property owner. Tenants typically insure contents and improvements only.
Contents & Equipment
Office furniture, computers, machinery, tools, manufacturing equipment, point-of-sale systems, and business fixtures that are not permanently attached to the building.
Stock in Trade
Raw materials, work-in-progress, and finished goods held on your premises. High-value stock or stock with significant seasonal variation may need special declaration or endorsement.
Leasehold Improvements
Improvements you have made to leased premises — shopfitting, partitioning, air conditioning, and other upgrades that are at your financial risk even though the building belongs to the landlord.
What Events Are Typically Covered?
The fire section covers more than just fire. Most South African commercial fire sections extend to a standard group of named perils. These typically include:
- › Fire, including fire resulting from explosion
- › Lightning and thunderbolt
- › Explosion (subject to conditions regarding boilers and pressure vessels)
- › Aircraft and aerial devices (impact or articles dropped from)
- › Storm, wind, water, hail, and snow
- › Impact by vehicles or animals
- › Earthquake and subterranean fire (where included)
It is important to note that these perils are typically named and listed. If the cause of your loss is not a named peril, you are unlikely to have cover under the fire section. Always check your specific policy wording with your broker.

Common Causes of Commercial Fire Claims
Understanding how fires start is as important as knowing what your policy covers. These are the most common causes seen in South African commercial fire claims:
Electrical Faults
Overloaded circuits, faulty wiring, and aging electrical infrastructure are the leading cause of commercial fires in South Africa.
Load Shedding Damage
Power surges when electricity is restored after load shedding can ignite equipment that was left switched on. This is a uniquely South African risk that has increased significantly.
Lightning Strikes
South Africa's highveld experiences some of the world's highest lightning activity. Direct and indirect strikes cause fires and equipment damage annually.
Arson
Deliberate fire-setting by third parties, disgruntled employees, or in connection with civil unrest. Note that arson by the insured or with their knowledge is excluded.
Human Error
Unattended cooking equipment, discarded cigarettes, and improper storage of flammable materials account for a significant proportion of claims.
Heating Equipment
Gas heaters, paraffin stoves, and electric bar heaters used in unventilated spaces or near flammable materials are a common ignition source, especially in winter months.
Manufacturing Processes
Welding, cutting, grinding, and heat-generating production processes carry ignition risk. Hot work permits and protocols are essential in manufacturing environments.
Flammable Liquids
Fuel, solvents, paint, and cleaning chemicals stored incorrectly on business premises represent significant fire and explosion risk. Storage requirements may affect your cover.
What Is Normally Excluded?
Understanding exclusions is as important as understanding what is covered. The following are standard exclusions found in most South African commercial fire sections. This is not an exhaustive list — your policy wording will contain the definitive exclusions applicable to your cover.
Important Exclusions to Understand
- ✕ War, invasion, act of foreign enemy, and civil war
- ✕ Riot and strike (usually covered under a separate section or SASRIA)
- ✕ Terrorism (covered separately through SASRIA in South Africa)
- ✕ Deliberate acts by the insured or with the insured's connivance
- ✕ Nuclear risk and radioactive contamination
- ✕ Spontaneous fermentation or heating (e.g. in grain, compost, or certain chemicals)
- ✕ Faulty design, workmanship, or materials (though damage caused by resulting fire may be covered)
- ✕ Consequential losses, lost profit, or business interruption (separate section required)
Note regarding SASRIA: South Africa has a unique insurance vehicle called SASRIA (South African Special Risks Insurance Association) which covers losses caused by civil unrest, riots, strikes, and public disorder. Most commercial policies automatically include SASRIA cover at a nominal premium. Ask your broker to confirm that your policy includes SASRIA.
Replacement Value vs Market Value: A Critical Distinction
Replacement value is the cost to replace your damaged or destroyed property with new property of a similar kind and quality at current prices. This is the basis most commercial fire policies use to settle claims.
Market value (or indemnity value) is the current market price of the property taking into account its age, condition, and depreciation. A ten-year-old machine may have a market value of R50,000 but a replacement cost of R280,000.
If your policy is written on a replacement value basis, your sum insured must reflect what it would cost today to replace everything new. If you insure on a market value basis, your payout will be significantly lower. Know which basis applies to your cover.
How to Calculate the Correct Sum Insured
Incorrect sum insured is the single biggest problem in South African commercial fire insurance. Underinsurance is widespread, and it has devastating consequences at claim stage.
Here is a practical framework for calculating each category of insured property:
Critical Warning
The Average Clause: Why Underinsurance Is Financially Catastrophic
The average clause (also called the co-insurance clause) is one of the most misunderstood provisions in commercial fire insurance. It is also one of the most financially dangerous.
Here is how it works in plain language:
If your property is worth R2,000,000 to replace but you have insured it for only R1,000,000, you are 50% underinsured. When you submit a fire claim — even if the damage is only R500,000 — the insurer will apply the average clause and pay only 50% of your claim, which is R250,000. You bear the remaining R250,000 yourself.
The Formula
Claim Payout = (Sum Insured ÷ Actual Replacement Value) × Loss Amount
The average clause means that underinsurance is not simply a problem in the event of a total loss — it affects partial losses too. Every claim is penalised in proportion to the degree of underinsurance. Speak to an AS Brokers adviser to review your sums insured before your next renewal.
Common Mistakes Business Owners Make
Using the municipal valuation as the building sum insured.
Municipal valuations are based on market value for rating purposes, not rebuilding cost. They are almost always lower than the actual cost to rebuild.
Not updating sums insured after purchasing new equipment.
Every new major purchase should trigger a review of your contents sum insured. Midyear additions are often forgotten until a claim reveals the gap.
Forgetting tenant improvements and leasehold upgrades.
Many tenants believe their landlord's insurance covers their shopfitting. It does not. Your investment in the leased space is your financial risk.
Insuring stock at selling price rather than replacement cost.
Fire policies insure stock at the cost of replacement, not the retail selling price. Your sum insured for stock should reflect what you would need to spend to replenish it at wholesale cost.
Not checking whether SASRIA cover is included.
The July 2021 civil unrest showed how quickly riot and looting damage can occur. Confirm SASRIA is attached to your policy and understand what it covers.
Not conducting a proper inventory before a claim is needed.
After a fire, proving what you had and what it was worth is your responsibility. Without records, your claim may be undervalued or disputed.
Questions to Ask Your Broker Every Year
A meaningful annual insurance review goes beyond simply renewing existing cover. These are the questions every business owner should put to their broker each year:
- 1. Are my sums insured still adequate given current building and equipment replacement costs?
- 2. Does my policy include SASRIA cover for civil unrest and riot?
- 3. Is my policy written on a replacement value or indemnity (market value) basis?
- 4. Does the average clause apply to my policy, and if so, what is my current risk of underinsurance?
- 5. Have I added any new equipment, stock, or made any improvements to the premises that are not yet reflected in my policy?
- 6. Am I covered for power surge damage related to load shedding, and is it adequate?
- 7. If I store or use flammable materials or hazardous substances, are they correctly disclosed and covered?
- 8. What is my policy excess, and has it changed on renewal?
- 9. Am I aware of any new warranties or conditions that have been added to my policy that could affect a fire claim?
- 10. Do I understand the claims process, and who do I contact first in the event of a fire?
"The most expensive fire insurance mistake a business owner can make is discovering they are underinsured at the moment they need their policy most."

Documents to Keep in Case of a Claim
In the event of a fire, you will need to substantiate your claim with documentation. The burden of proof rests with you as the insured. Keep the following records in digital format stored securely off-site or in cloud storage — not only on your premises:
- › Current asset register listing all contents and equipment with purchase dates and values
- › Purchase invoices and receipts for major items
- › Photographs and video of all business premises, equipment, and stock (updated annually)
- › Stock records, inventory lists, and stock valuations
- › Building plans, improvement cost records, and contractor invoices
- › Your current policy schedule and wording
- › Contact details for your broker and insurer's claims line
- › Service and maintenance records for electrical systems, fire equipment, and machinery
Practical Risk Management: Reducing the Chance of a Fire
Good fire risk management does more than protect your property — it demonstrates responsible stewardship to your insurer and may support more favourable underwriting terms over time. These practical steps are relevant to most commercial premises:
Electrical Safety
Commission a professional electrical compliance certificate (CoC) every few years and immediately after any major installation. Replace aging wiring. Install surge protectors and UPS systems to manage load shedding risks.
Fire Detection and Suppression
Install and maintain smoke detectors, heat detectors, and fire extinguishers appropriate to your risk type. Sprinkler systems significantly reduce fire damage in larger premises. Inspect and service fire equipment annually.
Flammable Materials Management
Store flammable substances in compliant, dedicated storage areas away from ignition sources. Ensure compliance with the Occupational Health and Safety Act (OHS Act) storage requirements. Dispose of flammable waste promptly.
Staff Training and Procedures
Train employees in fire evacuation procedures. Designate fire wardens. Implement a no-smoking policy inside and near the building. Issue a hot work permit system for any cutting, welding, or grinding work.
Security and Access Control
Good physical security reduces arson risk. CCTV and monitored alarm systems deter deliberate fire-setting and provide evidence if a fire occurs. Report suspicious activity promptly.
Housekeeping
Good housekeeping is one of the most effective fire prevention measures. Clutter, waste paper, cardboard, and combustible materials are fuel. Keep storage areas organised and fire exits clear at all times.
Self-Assessment

Common Questions
If only part of my building is damaged, will my claim be reduced because of underinsurance?
Yes. The average clause applies to partial losses, not just total losses. If your building is worth R3 million to rebuild but you have insured it for R1.5 million, and a partial fire causes R600,000 in damage, you will receive only R300,000. The proportion of underinsurance is applied to every claim regardless of its size.
Does fire insurance cover damage caused by the water used to extinguish the fire?
Yes, in most cases. Water, foam, and smoke damage caused as a direct result of fighting a fire is typically covered under the fire section as a consequential result of the fire peril. However, verify this in your specific policy wording.
What happens if my premises catch fire during load shedding and the fire spreads because the alarm system lost power?
Fire resulting from a surge on power restoration is generally covered under the fire section, subject to policy conditions. However, your insurer may investigate whether proper surge protection was installed. Some policies include specific warranties or conditions relating to electrical protection measures. Speak to an AS Brokers adviser about your specific policy conditions.
I rent my premises. Do I need fire insurance?
Yes. As a tenant, you are responsible for insuring your contents, equipment, stock, and any improvements or alterations you have made to the leased premises. Your landlord's building insurance does not cover any of your property. In many lease agreements, you are also required by contract to maintain adequate fire cover.
