ISR vs Business Pack: Which Policy Does Your Property Need?

If you own commercial property and you’re trying to figure out the difference between ISR and a business pack, you’re asking the right question. These two products get confused constantly, and picking the wrong one can cost you thousands - or leave you dangerously underinsured.

Let me break it down properly.

Key Takeaways:

• Business packs cover named perils and bundle property + liability. ISR covers all risks and is property-only.
• ISR is individually underwritten. Business packs are automated, packaged products.
• For standard properties under $5M, a business pack is usually fine.
• When mainstream insurers decline or overprice, ISR often delivers better cover at lower cost.
• We saved one client $29,000 by moving from a business pack alternative to ISR placement.

The Fundamental Difference

This is the single most important thing to understand, and most property owners don’t realise it.

A business pack covers named perils. That means the policy lists specific events - fire, storm, theft, malicious damage - and only those events are covered. If something happens that isn’t on the list, you’re out of luck.

An ISR policy works on an all-risks basis. Rather than listing what’s covered, it lists what’s excluded. Instead of a list of what’s in, you get a shorter list of what’s out.

In practice, this means ISR has far fewer gaps. Things that might not be covered under a business pack - accidental damage, impact, certain water damage events - are automatically included under ISR unless they’re explicitly excluded.

It’s a fundamentally different approach to insurance, and for complex properties, it usually means better protection.

How Business Packs Work

Business packs are the standard product from mainstream insurers. CGU, QBE, Vero, Hollard - they all offer them. Here’s what you’re getting:

• Property and liability bundled together. One policy covers your building, contents, and public liability. Convenient, but it means neither part is individually tailored.
• Automated underwriting. You punch in some details, the system spits out a price. Quick and easy, but it means the insurer hasn’t actually looked at your specific property.
• Named perils basis. Only the events listed in the policy are covered.
• Capacity limits. Most business packs cap out between $5M and $10M for building sum insured. Some won’t touch certain postcodes or tenant types at all.

For standard properties - a simple office, a retail shop, a clean warehouse under $5M - business packs work perfectly well. They’re affordable, fast to arrange, and give you decent cover.

The problems start when your property isn’t standard.

How ISR Works

Industrial Special Risks insurance is a different beast entirely:

• All-risks basis. Broader cover with fewer gaps.
• Property only. Liability gets arranged separately, which means each part is properly tailored to your situation.
• Individual underwriting. A real person reviews your property details, construction, tenancy, location, fire protection, and flood exposure. The policy is built around your specific risk.
• Higher capacity. ISR can cover properties worth $50M, $100M, or more. Significantly higher limits than standard products.
• Specialist markets. Underwriters like Ocean, Halo, Axis, and Lloyd’s syndicates. These are specialists who understand complex properties.
• Tailored endorsements. Cover can be adjusted with specific extensions and conditions that match your property’s risk profile.

The trade-off is that ISR takes more work upfront. Your broker needs to prepare a proper submission with construction details, tenancy schedules, flood data, and fire protection info. It’s not a five-minute online process. But the result is often a better fit for the property.

Side-by-Side Comparison

Here’s how the two products stack up:

Feature	Business Pack	ISR
Policy basis	Named perils	All risks
Underwriting	Automated/packaged	Individual assessment
Liability included	Yes (bundled)	No (arranged separately)
Typical capacity	Up to $5M-$10M	$50M+ available
Flood cover	Often excluded or capped	Can be included and negotiated
Tenancy flexibility	Limited (declines complex tenants)	Assessed individually
Quote turnaround	Minutes to hours	Days to weeks
Markets	CGU, QBE, Vero, Hollard	Ocean, Halo, Axis, Lloyd’s
Best for	Standard, low-complexity properties	Complex, high-value, or declined risks

5 Signs You’ve Outgrown a Business Pack

Business packs aren’t bad products. But they have a ceiling. Here are five signs your property has hit it:

1. Your building is valued over $5M. Most business packs can’t provide adequate capacity above this threshold. Even if they can technically cover it, the pricing often isn’t competitive.

2. You’ve been declined by two or more mainstream insurers. When multiple standard insurers say no, it’s not the end of the road. It usually means your property doesn’t fit their packaged product. ISR markets see these properties every day.

3. Your tenants are complex. Mechanics, spray painters, food manufacturers, restaurants, auto electricians. Business packs either exclude these tenants or load the premium so heavily that it doesn’t make sense.

4. Your property is in a flood zone. Standard products either exclude flood entirely or price it at a level that’s unworkable. ISR underwriters can assess flood exposure individually and often include it at a lower rate than what a mainstream insurer would charge - if they’d even offer it.

5. You own a multi-property portfolio. Managing five separate business packs with five different insurers and five different renewal dates is a headache. ISR lets you put everything on one policy with one renewal. In our experience, often more cost-effective too.

If two or more of those apply, ISR may be worth exploring.

Real Examples From Our Placements

Numbers tell the story better than I can. Here are three real placements from our book (details anonymised). Individual outcomes will vary based on your specific property and risk profile:

Western Sydney industrial warehouse. The owner was getting quoted $44,000 on the only business pack product that would cover it. Complex tenancy mix, older building, high sum insured. We took it to the ISR market and placed it at $15,000. That’s $29,000 saved - same property, better cover. The ISR policy actually had broader protection because of the all-risks basis.

Flood-zone commercial complex in Northern NSW. Ten mainstream insurers declined. Every single one. Flood exposure was the deal-breaker - no business pack product would touch it. We prepared a detailed ISR submission with flood mapping, mitigation measures, and construction data. Placed it at $80,000 including flood cover. Without ISR, this owner would have been uninsured. And being underinsured or uninsured on a property worth millions isn’t a risk anyone should be taking.

Vacant warehouse in South Melbourne. Seven declines on standard products. Vacant properties are notoriously hard to insure through mainstream channels - most business packs exclude them outright. ISR placed at $3,000. Clean, simple, done.

These aren’t unusual cases. This is what we see every week. Properties that don’t fit packaged products finding better outcomes through ISR.

Making the Switch

If you’re currently on a business pack and thinking about ISR, the process is straightforward:

We review your current cover. We look at what you’ve got, what gaps exist, and whether ISR would actually be a better fit. Sometimes a business pack is the right call - we’ll tell you that.

We prepare the ISR submission. Construction details, tenancy schedule, fire protection, flood data, photos, claims history. We handle all of this.

We market it to ISR underwriters. Your property goes to the specialist markets. We negotiate the best terms available.

We arrange liability separately. Because ISR is property-only, we place your public liability and any other liability covers with the most appropriate insurer. This often means better pricing on both parts.

You end up with one properly structured insurance program instead of a packaged product that was never designed for your property.

The whole process usually takes one to two weeks. We handle the heavy lifting. You just need to provide the property details and answer a few questions.
