Business Interruption Insurance

Protect your revenue and cover ongoing expenses when an insured event forces your business to stop trading.

Business interruption insurance covers the financial losses a business suffers when it is unable to trade following an insured event. A fire that destroys your shopfront, a flood that renders your warehouse unusable, or storm damage that closes your office for weeks can cause revenue losses that far exceed the physical property damage itself. While building and contents insurance pays to repair or replace damaged property, business interruption insurance replaces the lost income and covers ongoing expenses during the recovery period, keeping your business financially viable until normal trading resumes.

How Does Business Interruption Insurance Work?
Business interruption insurance is always linked to a material damage policy. A BI claim can only be triggered when there is a valid claim under your building or contents insurance. Once the material damage claim is accepted, the BI policy kicks in to cover the financial consequences of the interruption. The policy pays the reduction in gross profit (or revenue, depending on the policy basis) caused by the interruption, plus any additional costs the business incurs to minimise the interruption, such as temporary premises, equipment hire or outsourcing production. Cover continues for the duration of the indemnity period or until the business returns to pre-loss trading levels, whichever comes first.

What Does Business Interruption Insurance Cover?

  • Loss of Gross Profit: Covers the shortfall in gross profit caused by the reduction in turnover during the interruption period. This is the core of most BI policies.
  • Ongoing Expenses: Covers fixed costs that continue during the interruption, including rent, loan repayments, employee wages, insurance premiums and utilities.
  • Additional Cost of Working: Covers extra expenses incurred to reduce the interruption, such as renting temporary premises, hiring replacement equipment, express freight charges and overtime wages.
  • Loss of Rent (Landlords): For property owners, covers the rental income lost when a tenanted property becomes unusable following an insured event.
  • Claims Preparation Costs: Many policies cover the cost of engaging an accountant to prepare and substantiate the business interruption claim.
  • Customers and Suppliers Extensions: Optional extensions cover losses caused when a key customer's or supplier's premises suffer damage, even if your own property is unaffected.

Understanding the Indemnity Period
The indemnity period is the maximum length of time the policy will pay out following an insured event. Standard indemnity periods are 12, 18 or 24 months, with some insurers offering up to 36 months. Choosing the right indemnity period is critical. It must be long enough to cover the worst-case scenario, which includes the time to assess damage, obtain council approvals, rebuild or repair the premises, refit the interior, restock and re-establish your customer base to pre-loss levels. Many businesses underestimate this timeframe. A major fire in a commercial building can easily take 18 to 24 months from damage to full recovery.

Calculating Your Sum Insured
Business interruption sums insured must be calculated carefully based on the policy basis selected:

  • Gross Profit Basis: The most common basis. Gross profit equals turnover minus variable costs (purchases, raw materials, freight). The sum insured should be the gross profit for the full indemnity period.
  • Revenue Basis: Used by service businesses with high fixed costs and low variable costs. The sum insured is the total revenue for the indemnity period.
  • Additional Cost of Working: For businesses that can continue operating from alternative premises but at higher cost, this covers only the extra expenses incurred.
Underinsurance is common in business interruption claims. If your declared sum insured is less than the actual amount at risk, the insurer will apply averaging and reduce your claim proportionally. Shielded recommends reviewing BI sums insured with your accountant annually.

What Affects Business Interruption Insurance Premiums?

  • Sum Insured: The declared gross profit or revenue figure drives the base premium.
  • Indemnity Period: Longer indemnity periods increase the premium but provide better protection.
  • Business Type: Manufacturing and hospitality businesses carry higher BI risk than professional services due to longer recovery times.
  • Location: Properties in flood, cyclone or bushfire zones attract higher premiums due to greater likelihood and longer duration of interruptions.
  • Extensions: Adding supplier and customer dependency extensions increases the premium.
  • Claims History: Previous BI claims affect future pricing and insurer appetite.

Why Business Interruption Cover Is Essential
Statistics consistently show that many small businesses that suffer a major property loss never reopen. The reason is rarely the property damage itself, which is covered by building and contents insurance. The real threat is the loss of revenue during what can be a prolonged recovery period, compounded by ongoing expenses that do not stop just because trading has. Rent, wages, loan repayments and utilities continue regardless. Business interruption insurance bridges this gap. Shielded works with CGU, QBE, Zurich, Vero, Hollard, Allianz and AIG to ensure your BI cover accurately reflects your revenue, expenses and realistic recovery timeframe.

Frequently Asked Questions

Questions about Business Interruption Insurance and General Enquiries

How much does business interruption insurance cost in Australia?

Business interruption insurance typically costs between $500 and $5,000 per year for small to medium businesses, depending on the sum insured, indemnity period, business type and location. It is usually purchased as part of a broader commercial property package, which can reduce the overall cost. Contact Shielded for a free quote based on your specific business financials.

Can I claim business interruption without property damage?

Standard business interruption policies require an underlying material damage claim. If there is no physical damage to an insured property, the BI policy does not respond. However, some policies include extensions for prevention of access (where authorities deny access to your premises), infectious disease outbreaks and utility failure, which can trigger a BI claim without direct property damage.

What is the difference between gross profit and net profit for BI insurance?

In insurance terms, gross profit means turnover minus variable costs such as purchases and raw materials. It is not the same as accounting gross profit. Net profit is not typically used as a BI insurance basis because it does not capture the ongoing fixed expenses that business interruption insurance is designed to cover.

How long does the indemnity period need to be?

The indemnity period should cover the entire time from the date of damage through to when the business returns to pre-loss trading levels. For most businesses, 12 months is the minimum, but 18 to 24 months is recommended. Businesses dependent on custom-built equipment, specialist fit-outs or council-approved rebuilds should consider 24 to 36 months.

Does business interruption insurance cover pandemics?

Most standard business interruption policies do not cover losses arising from pandemics. Following the COVID-19 experience, most insurers have introduced specific pandemic and communicable disease exclusions. Some policies include limited infectious disease extensions, but these typically apply to localised outbreaks at or near the insured premises, not widespread pandemics.

What is the additional cost of working?

Additional cost of working covers the extra expenses your business incurs to continue operating or to minimise the interruption. Examples include renting temporary premises, hiring replacement equipment, paying overtime wages, express shipping costs and outsourcing production. These costs are covered provided they reduce the overall loss to the insurer.

Do I need business interruption insurance if I work from home?

If your business relies on physical premises, stock, equipment or a specific location to generate revenue, business interruption insurance is important. Home-based businesses with minimal physical dependencies may have less need, but any business that would lose income following a fire, flood or major property event should consider BI cover.

Which insurers offer business interruption insurance in Australia?

All major commercial insurers in Australia offer business interruption cover, including CGU, QBE, Zurich, Vero, Hollard, Allianz and AIG. BI is typically packaged with building and contents insurance in a commercial property policy. Shielded compares BI options across our insurer panel to ensure your cover and indemnity period match your business needs.

What types of properties can be insured under commercial property insurance?

Commercial property insurance covers a wide range of property types including office buildings, retail shops, warehouses, factories, shopping centres, hotels, motels, restaurants, cafes, medical centres, child care centres, gyms, salons, laundromats, churches, petrol stations, mixed-use developments and more. Whether you own a single tenancy or a multi-storey complex, we tailor cover to match your property.

How much does commercial property insurance cost in Australia?

Premiums vary based on building value, location, construction type, tenant occupation and risk profile. A small retail shop may cost $1,500 to $4,000 per year, a standard office building $3,000 to $10,000, and a large warehouse or industrial property $5,000 to $25,000+. High-risk tenancies (restaurants, manufacturing) attract higher premiums. Request a free quote through Shielded for an accurate indication.

What does commercial building insurance cover?

Commercial building insurance covers the physical structure including walls, roof, floors, fixed fixtures, common areas, car parks, fencing and services (electrical, plumbing, HVAC) against fire, storm, flood, impact damage, malicious damage, theft and accidental damage. It typically also covers demolition and removal costs, professional fees (architects, engineers) and compliance with current building codes when rebuilding.

Do I need landlord insurance or commercial property insurance?

If you own a commercial building and lease it to tenants, you need commercial landlord insurance. This covers the building structure, landlord's contents (common area furnishings, HVAC systems), public liability for common areas, loss of rental income if the building is uninhabitable after an insured event, and plate glass. Your tenants are responsible for insuring their own contents, stock and fit-out.

What is loss of rental income cover?

Loss of rental income (also called business interruption for landlords) provides replacement income if your commercial property becomes uninhabitable after an insured event such as fire, storm or flood. It covers the rental income you would have received during the repair or rebuild period, typically for up to 12 or 24 months. This is essential for property investors who rely on rental returns.

Is plate glass cover included in commercial property insurance?

Plate glass cover is usually an optional add-on, not included in the base building policy. It covers the cost of replacing glass shop fronts, windows, doors, display cases and signage glass that is accidentally broken or vandalised. For retail properties with large glass frontages, this is an important cover to include.

Who is responsible for insurance - the landlord or the tenant?

Generally, the landlord insures the building structure, common areas and landlord's fixtures. Tenants are responsible for insuring their own contents, stock, fit-out, trade fixtures and their own public liability. Most commercial leases clearly define these responsibilities. As a landlord, ensure your lease requires tenants to hold adequate insurance and provide certificates of currency.

Who do I contact to make a claim?

Contact us at Shielded Insurance on 1800 97 98 99 or reach out to your insurer directly. We recommend notifying us as soon as possible after damage occurs, documenting everything with photos, securing the premises to prevent further damage, and keeping records of all emergency repair costs.

Which insurers does Shielded compare for commercial property?

We compare quotes from leading Australian commercial property insurers including CGU, QBE, Zurich, Vero, Hollard, Allianz, AIG and others. The best insurer depends on your property type, construction, tenant occupation and risk profile. As brokers, we do the comparison work to find competitive and suitable cover for your property.

How often should I review my commercial property insurance?

Review your policy annually at renewal, or whenever there are significant changes such as new tenants, renovations, extensions, changes in building use, or updated valuations. Building replacement costs increase over time - if your sum insured does not keep pace with construction cost inflation, you risk being underinsured at claim time. We recommend a professional building valuation every 3 to 5 years.
