Business Insurance Consulting is Brisbane's premier contract works insurance broker. Contract works insurance can cover accidental damage to a building while it is under construction, and may include public liability and theft of materials, depending on the policy. For Brisbane builders, it should be arranged before work starts, with the cover dates and project details checked against the contract.

What contract works insurance can cover
Contract works insurance, sometimes called construction works insurance, is designed to protect the work in progress against accidental physical loss or damage during the insured period. Depending on the policy, it can also include public liability cover and theft of materials.
The contract value is usually the starting point for the project sum insured. Check what the policy counts as value, including labour, materials supplied by others, temporary works and any changes to the scope. If the value is too low, underinsurance could leave a shortfall after a major loss.
The material damage section may cover the building as it takes shape, along with declared materials and temporary structures. But cover varies. Review the policy schedule and wording for the events insured, theft conditions, excesses and limits. Don’t assume that every item on site is automatically covered.
Public liability addresses a different risk: legal responsibility if the work causes injury to someone else or damage to their property. It does not replace cover for damage to the project itself.
Who should consider cover for a building job?
Principal contractors arranging a build, extension or renovation should check who is responsible for insuring the work under the contract. An owner-builder with the required licence may also need to arrange cover for a project. Subcontractors taking on a larger job should confirm whether the principal contractor’s policy covers their work, or whether they need their own arrangement.
Carpenters, concreters, bricklayers and other trades should not rely on assumptions. Ask for the relevant policy details and confirm that the work, site and contract period are included. The contract may also set requirements for liability limits, interested parties and evidence of insurance.
For wider business protection, Business Insurance Brisbane can include more than a single project policy. Builders may also need to consider Public Liability Insurance Brisbane and Commercial Property Insurance Brisbane for other business exposures, and Insurance Broker Brisbane services can help line up the full set of covers around each contract.
What affects the cost in Brisbane?
There is no single set price for contract works insurance. As a broad, indicative guide only, some market estimates put the premium around 0.1%–0.3% of the project value. That could mean roughly $500–$1,500 for a $500,000 project. It is not a quote or a guaranteed rate. Actual premiums vary with the contract value, build type and cover selected.
The insurer may also consider:
- How long the build is expected to take.
- The site location and its exposure to flood, storms and other hazards.
- The type of construction and materials used.
- Higher-risk activities, such as roofing and formwork.
- The amount of liability cover, excesses and any special conditions.
A Brisbane renovation and a larger build in a storm- or flood-exposed area may be assessed differently. Accurate information about the job helps avoid surprises when arranging cover.
Why cover needs to start before work starts
A loss can happen at any point after site handover and before practical completion. Materials may be stolen before they are installed. A storm can damage exposed framing. An accident can affect work that has already been completed.
If the policy is not active when the loss happens, you may have to pay the repair or replacement costs yourself. Arranging cover after work has started does not necessarily protect damage that has already occurred. Match the policy start date to the actual handover and work start, not just the date you expect the first major trade to arrive.
In South East Queensland, storm season runs from November to April. Open structures, exposed framing, scaffolding and temporary works can face particular weather risks during this period. Check how the policy treats storm, flood and wind damage, and what site protection measures are required.

Know the common gaps and exclusions
Contract works cover is not a promise that every repair will be paid. Policies often exclude the cost of correcting defective workmanship, design or materials. Some wording may treat resulting damage differently from the cost of fixing the original defect. Read the policy details and ask how the distinction applies to the work you do.
The defects or maintenance period can also cause confusion. Practical completion, handover and any defects period are not always treated the same way by a policy. Confirm when cover ends and whether any extension is available or needed.
Tools and equipment away from the site are often not covered by a contract works policy. They may need separate cover, particularly if tools are kept in a vehicle or moved between jobs. Check what is covered on site, off site and in transit.
A practical checklist before the next job
Save this list and review it before site handover:
- Confirm the contract value matches the policy sum insured.
- Align policy dates with the work start and expected practical completion; ask how the defects period is treated.
- Check what insurance your subcontractors must hold and provide.
- Confirm the public liability limit matches the contract requirements.
- Note whether materials are stored on site or off site, and check the applicable cover.
- List higher-risk activities, including roofing, formwork and scaffolding.
- Check whether the principal requires their name to be noted as an interested party.
- Confirm storm-season protections and any flood, wind or storm conditions.
- Review the insurance obligations in the contract schedule.
- Arrange cover before site handover, not after work is under way.

Common questions about contract works insurance
What does contract works insurance cost in Brisbane?
As a broad guide only, some market estimates suggest around 0.1%–0.3% of the project value. This is not a quote. The actual premium varies with contract value, build type, duration, location, activities and selected cover.
Do owner-builders need contract works insurance?
An owner-builder with a licence should check the contract, project arrangements and policy options before work begins. The need and appropriate cover depend on the build and who is responsible for insuring the work.
Is contract works the same as public liability?
No. Contract works can cover accidental damage to the project under construction. Public liability is for covered legal liability if the work causes injury to someone else or damages their property. One does not automatically replace the other.
Does contract works cover tools and equipment?
Not necessarily. Tools and equipment may need separate cover, particularly when they are off site or in transit. Check the policy wording and schedule.
When should contract works insurance start?
Arrange it before work begins and confirm the start date covers the period from site handover. Check the end date against the expected practical completion and ask how any defects or maintenance period is treated.
