Brisbane builders carry risk in several directions at once. A renovation in an older inner-city suburb brings structural surprises. A townhouse project brings contract works, subcontractor coordination and a fixed handover date. A commercial fitout brings design responsibility and a landlord watching the clock. No single policy covers all of that, which is why builders insurance is really a program rather than a product.
Business Insurance Consulting is a Brisbane-based brokerage led by Craig Graham, who has 28 years of experience in the industry. The team places construction and trades risks with a panel that includes CGU, QBE, Vero, Allianz, AIG, Chubb, Zurich and NTI, and works through Community Broker Network and Steadfast with NIBA affiliation. Panel breadth matters in construction, because insurer appetite for particular trades, project types and contract values shifts from one renewal to the next.
Why one policy is rarely enough
Builders risk insurance is designed to protect a specific project and to cover principal contractors working on it. That cover usually starts when work begins and stops when the job is finished, handed over or the policy period ends. Public liability, professional indemnity, and plant and equipment cover work differently. They sit with the business rather than the job, and they keep running across every site the business touches during the year.
That split is where Brisbane builders often come unstuck. A builder with three jobs in progress may need a contract works schedule that lists each one, plus a liability policy that responds to incidents on all of them. Get the structure wrong and the gap tends to appear on the site that matters most, usually at the worst possible time.
The core covers in a builder’s insurance program
Most builder programs in Queensland are built from the same handful of components. What changes between businesses is the limit, the excess, the sub-limits and the way each policy talks to the others.
| Cover | What it responds to |
|---|---|
| Contract works and material damage | Works in progress, materials on site and materials stored off site, including insured events such as fire, storm, theft, vandalism and accidental damage |
| Public liability | Injury to third parties or damage to property that does not belong to you |
| Plant and equipment | Owned or hired machinery, tools and mobile plant, including items taken from a vehicle or a locked site |
| Professional indemnity | Claims arising from design, specification or professional advice you provide |
Public liability
Public liability is the cover most builders meet first, usually because a head contractor or a principal asks for a certificate before work starts. It responds when someone outside your business is injured or their property is damaged in connection with your work. Limits are set by contract, and the limit a principal demands is often higher than what a small operator would choose. Check the required limit at tender stage rather than after the contract is signed.
Contract works and material damage
This is the project-based piece. It covers the works themselves while they are being built, along with materials waiting to be installed. Two details drive most disputes: whether materials stored off site are included, and whether the sum insured reflects current rebuild costs. Both are worth confirming in writing before the first delivery arrives on site.
Plant, tools and equipment
Tools disappear. Excavators, compactors, laser levels, generators and trailers are all mobile, valuable and attractive to thieves. Cover can extend to owned and hired items, but the conditions around overnight storage, locked compounds and unattended vehicles vary widely between insurers. A policy that looks cheap on paper may exclude exactly the scenario that happens most often on Brisbane sites.
Professional indemnity
Design and construct work blurs the line between building and professional advice. If you specify a product, prepare a design or provide technical recommendations, a professional indemnity policy is what responds when someone alleges the advice caused a defect or a financial loss. Builders who only ever build to someone else’s drawings may still need it if they make design decisions on site.
Domestic building insurance and owner builder cover
The difference between project cover and business cover shows up most clearly in residential work. Domestic building insurance exists to protect the homeowner rather than the builder. It gives homebuyers peace of mind that they are financially protected if construction or renovation issues arise, for example if the builder dies during the project, subject to the rules of the relevant scheme.
Those rules are set state by state, so a Queensland builder should confirm the current requirements, thresholds and eligible work types with the relevant regulator before quoting a residential job. Owner builder insurance is a separate product, purpose-built for individuals managing their own residential construction or renovation project instead of engaging a licensed builder for the full scope. It is a different risk again, and it is rated differently.
Subcontractor insurance: where gaps usually appear
Builders across Brisbane, Sydney, Melbourne and Perth are expected to make sure their subcontractors hold the right insurance, and that obligation does not disappear because a subcontractor says they are covered. Collecting certificates of currency at the start of a job is only half the task. Certificates expire, trades switch insurers, and a carpenter who was covered in January may not be covered in July when the frame goes up.
A practical routine is to collect certificates before any trade starts on site, diarise every expiry date, and check that the policy actually responds to the work being performed. A general liability policy with a residential exclusion will not help anyone after an incident. Where a subcontractor cannot produce adequate cover, the exposure usually lands back on the principal contractor.
Broker or direct: how Brisbane builders usually buy cover
One of the first structural decisions on any construction insurance program is whether to place cover through a broker or buy directly from an insurer. Direct products can look simpler, and for a single trade with predictable turnover that approach sometimes works. Once a business runs multiple projects, hires plant, employs staff and engages subcontractors, the number of policies and the way they interact becomes the real issue.
A broker’s role is to compare how different insurers treat your specific mix of work, negotiate the terms, and then advocate for you when a claim lands. That advocacy is the part builders tend to value most, because construction claims are rarely straightforward and often involve several parties, several insurers and a principal contractor with its own legal team.
Getting your sums insured right
Underinsuring contract works or a completed building is one of the most common and most expensive mistakes on a builder’s program. Rebuilding costs and market values move independently, and a figure that looked generous a few years ago may now fall well short. Appointing an expert property valuer to carry out a building insurance assessment is a practical way to establish a defensible sum insured, and Brisbane has property valuation specialists who work in this area.
A 2026 renewal checklist for Brisbane builders
Renewals are the natural point to test whether a program still matches the business. Running through a short list before the paperwork is signed is far cheaper than discovering a gap after a claim.
- Confirm your declared turnover and the split between residential, commercial and design work.
- List every project currently in progress and check each one is scheduled on the contract works policy.
- Review your sum insured against current rebuild costs rather than last year’s figure.
- Check the public liability limit against what your head contractors and principals require.
- Update the plant and equipment schedule for anything bought, sold or hired during the year.
- Test your subcontractor certificates and expiry dates before the busy season starts.
- Tell your broker about any change in the type of work you take on, including new trades or new states.
- Read the exclusions on your policy, especially those covering unattended sites and overnight storage.
Getting help from a Brisbane brokerage
Construction insurance is not a set-and-forget purchase. The right structure depends on what you build, where you build it, who works alongside you and what your contracts require. A local broker who knows how Queensland insurers view particular trades can usually narrow the field quickly and explain the trade-offs in plain English rather than policy wording.

Before making any decision about cover, speak with a qualified adviser or the relevant regulator about your own circumstances.
Frequently Asked Questions
What insurance does a builder need in Queensland?
Most builders need public liability, contract works and material damage cover, and plant and equipment protection, with professional indemnity added where design or specification advice is part of the work. Residential projects can also trigger domestic building insurance requirements. The exact combination depends on your trade, turnover, contract conditions and the type of projects you take on, so it should be reviewed with a broker rather than copied from another business.
How much does builders insurance cost in Brisbane?
There is no standard price. Premiums are rated on turnover, trade, project values, claims history, the covers selected and the limits and excesses you choose. Two builders doing similar work can receive very different quotes because insurers assess risk differently. The practical approach is to have your details prepared, then compare quoted cover and conditions rather than headline prices alone.
How long is a builder liable for their work in Australia?
Liability periods are set by a mix of state legislation, contract terms and the nature of the defect, and they can differ between structural and non-structural items. Because this area is governed by law and by the specific contract you sign, confirm the position with the relevant regulator and take legal advice for your project before relying on any general time frame.
Do I need to insure my subcontractors?
You generally need to confirm that your subcontractors hold their own appropriate insurance rather than insuring them under your own policy. Builders are expected to check that cover is current and suitable for the work being done. Where a subcontractor has no adequate cover, the principal contractor can end up carrying the exposure, so collecting certificates and tracking expiry dates is essential risk management.
What is the difference between builders risk and owner builder insurance?
Builders risk insurance protects a construction project and typically covers principal contractors and builders running the work as a business. Owner builder insurance is purpose-built for individuals managing their own residential construction or renovation project rather than engaging a licensed builder for the full scope. The two products respond to different insured parties, and the terms should never be assumed to overlap.
