What Types of Insurance Do Construction Businesses Need?

Running a construction business in Australia involves more than managing projects, subcontractors, and deadlines, it also means managing risk. From accidental property damage to workplace injuries and contractual disputes, construction businesses face exposures that can quickly become financially devastating without the right insurance in place.

Understanding which types of construction insurance you actually need, and why, is essential for protecting your business, meeting contract requirements, and securing ongoing work.

Below, we break down the key insurance policies construction businesses should consider, and how they work together to form a solid risk management strategy.

Public Liability Insurance for Construction Businesses

Public Liability Insurance is the most critical insurance that a construction business should insure for. It’s a cover that protects your business for when claims are brought against you for negligence, or even alleged negligence for damages to third party property, or injury to third parties that are not your employees. Public Liability and Workers Compensation are considered the 2 non-negotiable insurances as the likelihood of a claim occurring are higher in this industry than others.

Construction is considered a high-risk industry. According to Safe Work Australia, construction consistently records one of the highest numbers of serious workplace injury claims, with falls, slips and trips among the leading causes of injury. These types of incidents don’t just affect workers, they can also involve clients, subcontractors or members of the public on site.

Apart from protecting your business and also the directors and employees again big financial trouble if something did happen, it also allows you to get work. For example, many residentials, larger companies that you may subcontract to, councils etc will request to see a copy of your public liability insurance before they will either award you the work or allow you to go on site to start work.

Contract Works Insurance which protects the Project Itself

While Public Liability Insurance protects against third-party injury or property damage claims, Contract Works Insurance covers the physical construction project itself while it is being built.

As construction insurance specialists, we regularly assist clients with contract works claims. For example, during the November 2025 hail storm, Lauren Spice personally managed a builders claim process, working with the insurer to assess damage and ensure the builder’s financial exposure was minimised where severe hail damage impacted a newly installed roof on a residential property under construction. Because the builder was responsible for the works at the time of loss, the policy responded to cover the damage.

Extreme weather events, including hail and storm damage are one of the most contract works claims that occur in Australia. In 2025, severe weather events triggered nearly 264,000 insurance claims across Australia and billions in insured losses, according to the Insurance Council of Australia.

This is exactly why Contract Works Insurance is critical for builders and trades who are responsible for materials, labour and project risk during construction. Without the right cover in place, unexpected events such as storm damage, theft or vandalism can result in significant financial loss.

Professional Indemnity Insurance which is For Advice, Design, and Errors

Professional Indemnity Insurance for the construction industry is an emerging insurance. Usually, we would think that professional indemnity insurance is for occupations such as insurance brokers, lawyers, accountants, etc however it is highly relevant to construction businesses that provide advice, design input or professional services as part of their role.

In construction, Professional Indemnity Insurance or Design and Construct Insurance responds in two main parts, depending on the policy type that has been organised. Please note that Design and Construct is not automatic under all professional indemnity insurance policies for the construction industry.

The first relates to claims arising from your own professional services, for example, project management advice, specification errors, or a breach of professional duty that leads to financial loss to a client, or third party.

The second involves claims connected to subcontracted design or advisory services. Builders can be drawn into disputes as a primary or secondary party where design consultants, engineers or other subcontractors have made errors that result in financial loss or rectification costs.

It is important to note that even if you haven’t signed a D & C Contract, this does not mean that you don’t have an exposure.

Workers Compensation Insurance

If you employ staff, Workers Compensation Insurance is mandatory in Australia. This insurance cover protects employees who suffer a work-related injury or illness and require time away from work.

Workers’ Compensation Insurance typically covers a portion of the employee’s lost wages during their recovery period, as well as reasonable medical and rehabilitation expenses associated with the injury. This may include hospital treatment, specialist consultations, physiotherapy and approved rehabilitation programs.

While the primary purpose of Workers’ Compensation Insurance is to protect employees, it also safeguards business owners and directors from significant financial exposure. Without this cover in place, an employer could be personally liable for wages, medical expenses and associated costs following a workplace injury.

The construction industry remains one of the highest-risk sectors for workplace injury in Australia. According to Safe Work Australia , there were 146,700 serious workers’ compensation claims lodged nationally, with construction accounting for approximately 12% of those claims,  making it one of the leading contributors to serious workplace injuries.

Tools and Equipment Insurance

Tool theft is one of the most common claims we see within the construction industry. As insurance brokers specialising in construction businesses, we regularly assist clients who have suffered losses due to stolen tools or damaged equipment.

For example, Lauren Spice recently managed a claim involving $25,000 worth of tools stolen from a construction company employee’s vehicle, despite the tools being secured inside a locked toolbox. The claim was lodged promptly and paid within two days, allowing the client to replace their equipment immediately and avoid significant disruption to their business operations.

Unfortunately, this type of incident is not uncommon. According to Australian crime statistics, theft from motor vehicles remains one of the most frequently reported property offences nationally, with tens of thousands of incidents recorded each year.

Theft from vehicles, including tradespeople’s tools and equipment stored on-site or in work vehicles contributes significantly to property crime in Australia. According to the Australian Bureau of Statistics, about 72,000 experienced motor vehicle theft in 2023–24

Tradespeople, whose vehicles often store high-value tools overnight, are particularly exposed to this risk.

Tools and Equipment Insurance can respond not only to theft but also to damage caused by insured events such as storm, fire and, in some cases, flood. Having the appropriate cover in place helps ensure that unexpected losses do not halt a project or create substantial out-of-pocket expenses for the business.

Plant and Machinery Insurance – For Larger Equipment

For businesses that own or hire significant machinery — such as excavators, loaders, or cranes — Plant and Machinery Insurance is often required.

This cover can protect against:

• Accidental damage
• Breakdown
• Theft
• On-site and off-site risks

Many hire agreements also require proof of insurance before equipment is released.

Management Liability Insurance – Protecting Business Owners

Construction business owners and directors face increasing exposure to regulatory investigations, employment disputes, and management-related claims.

Management Liability Insurance can provide cover for:

• Employment practices claims
• Workplace bullying or unfair dismissal allegations
• Regulatory fines and investigations
• Director and officer liabilities

As construction businesses grow, this type of cover becomes increasingly relevant.

Why Construction Insurance Isn’t One-Size-Fits-All

No two construction businesses face the same risks. Insurance requirements vary depending on:

• Trade type
• Business size
• Annual turnover
• Contract values
• Whether you employ staff or subcontractors
• The types of projects you work on

Relying on generic or “cheap” insurance can leave dangerous coverage gaps, particularly in construction, where claims are often complex and high-value.
