What Types of Insurance Should Every Construction Company Have in Australia?

If you're running a construction business in Australia be it residential, commercial, civil contracting, mining or owner-builder projects you face plenty of risks. Whether it's damage on site, a public injury claim, or professional advice gone wrong, having the right insurance can save your business. At Connect Business Insurance (CBI), we specialise in insurance specifically for construction companies, helping you get the right cover, adapt as you grow, and manage claims if something goes wrong.

Here’s a clear guide to the essential policies every business under the construction company insurance umbrella should consider.

1. Contract Works Insurance (Construction Insurance)

Also called “construction works” or “contract works” insurance, this is the foundation cover for your business.

• Protects work-in-progress, materials, tools and equipment against theft, fire, vandalism, weather damage and more.
  
• Covers physical loss or damage to the site before completion,
  
• Often includes public liability elements, depending on your package.

If a storm hits, tools get stolen, or fire damages the site, contract works insurance steps in saving you from delays and financial loss.

This is often mandatory for contracts, especially larger ones some clients won’t sign off without proof of cover.

2. Public and Product Liability Insurance

Third-party claims are a common concern in construction. Liability insurance protects you if someone is injured or property gets damaged due to your operations or products.

• Covers injury or damage caused by your site activities or equipment.
  
• Product liability protects against claims related to materials or workmanship defects.

Depending on contract or project scale, many clients expect minimum limits like $10 million per claim especially in Queensland and New South Wales.

3. Builders Warranty Insurance (Home Warranty / Domestic Building Insurance)

Mandatory in many states for residential projects over a certain value:

• Victoria: Domestic Building Insurance for contracts over $16,000.
  
• NSW: Home Building Compensation Fund cover above $20,000.
  
• Queensland: Home Warranty Insurance for residential work above $3,300.

This insurance protects homeowners if a builder dies, disappears, becomes insolvent, or fails to complete the work they can claim directly through this policy.

It’s separate from contract works and liability it safeguards the homeowner, not the builder but is required by law in many jurisdictions and carries serious fines if omitted.

4. Workers’ Compensation Insurance

If you have employees labourers, apprentices or staff you must hold workers’ compensation insurance.

• Covers medical costs and lost wages if a worker is injured or becomes ill at work.
  
• Requirements vary by state/territory but are usually mandatory.
  

CBI doesn’t underwrite these policies but brokers them through trusted insurers as part of your tailored cover suite.

5. Professional Indemnity Insurance

For companies that provide design, certification, engineering advice or consultancy services, mistakes or omissions can lead to costly claims.

• Covers legal defence costs and compensation if a client alleges negligence, breach of duty, or faulty professional advice.
  
• Especially relevant for engineers, certifiers and design consultants working in construction.

6. Management Liability Insurance

This covers directors, managers and the business against claims such as:

• Employment disputes (bullying, harassment, wrongful dismissal),
  
• Fraud or theft by staff,
  
• Regulatory breaches.

It’s often overlooked but crucial especially after growing internal exposure to risk and legal obligations.

7. Business Interruption (Continuity) Insurance

If your business faces interruption say storm damage or site loss this policy can help you keep running.

• Covers ongoing costs, lost revenue and increased expenses while under repair or rebuilding.
  
• Typically connected to property or contract works cover.

8. Commercial Motor Vehicle Insurance

If your business owns trucks, utes or vans, a standard vehicle policy might not give enough cover:

• You’ll want commercial/motor fleet insurance, potentially including goods in transit.
  
• These cover accidents, theft, and third-party liabilities arising from your fleet operations.

How to Choose the Right Insurance Package

Consider Your Work Type:

• Residential building projects? You’ll need home warranty plus contract works.
  
• Civil contracts, mining or major infrastructure? You may require higher liability limits, specialised cover like resource liability or environmental liability.

Match Cover to Jurisdiction:

Understand thresholds and obligations state by state:

• Victoria = Domestic Building Insurance over $16k,
  
• NSW = over $20k,
  
• Queensland = over $3,300.
  

Lump together for savings:

• Combine public liability, contract works and property policies in one package often lowers overall premiums.

Refresh regularly:

• As projects, turnover or contract sizes change, your cover needs may shift. Regular reviews keep gaps closed.

Frequently Asked Questions (FAQs)

1. Do I really need contract works insurance?

Yes. It protects your jobsite, materials and equipment before completion. Many clients demand proof of it without it, you risk major financial losses from weather events, theft or vandalism.

2. What’s the difference between public liability and professional indemnity?

• Public liability covers third‑party injury or property damage at or near your site.
  
  
• Professional indemnity covers errors or omissions in your design or consultancy services.

If you both build and certify or design, you may need both.

3. What is home warranty insurance and when is it needed?

Builders working on residential projects above a state threshold must take out home warranty or domestic building insurance. This covers homeowners if a builder dies, disappears, or becomes insolvent before completion.

4. Can a subcontractor rely on the builder’s insurance?

Sometimes. But subcontractors should check whether they're named on policies like public liability and contract works or consider separate cover to avoid gaps.

5. Are there penalties for missing required insurance?

Yes. In Victoria for example, substantial fines apply if domestic building insurance is not in place for eligible projects, and clients may refuse to engage builders without proof.

6. How does CBI help with claims?

We provide claims liaison and documentation support, negotiate with insurers, and advocate for fair settlements. This takes the workload off your plate and helps processes run fast and fair.
