A NSW builder’s insurance rarely fits into a single policy. The risks on a knock-down rebuild in the inner west look nothing like the risks on a commercial fit-out, and the cover that responds to storm damage on an open frame is not the cover that responds when a member of the public is injured beside the site fence. Insurance for construction companies is put together around those differences, which is why the same builder can end up with four or five separate policies sitting alongside each other.
This is a practical look at what those policies do, what NSW projects add to the picture, and what to have ready before you ask for a quote.
Why construction is treated as its own insurance category
Marsh Australia describes construction as layered with risks, and that layering is the reason a standard business pack usually falls short. The asset you are insuring changes shape every week. The site is temporary. Subcontractors and suppliers move in and out. A single incident can create an injury claim, a property damage claim and a contractual argument at the same time.
Liability cover for the sector is built to respond to claims involving bodily injury, property damage, contractual liability and related risks that arise from construction activities, according to Liberty Australia. A typical construction policy also includes cover for physical loss or damage to materials and equipment from events such as natural perils, theft and vandalism. Read together, those two descriptions explain the shape of most builder programs: one part protects the work and the things sitting on site, the other protects the business when someone else suffers a loss.
Projects also have a beginning and an end. Contract works cover is arranged for the duration of the works, while liability cover keeps running across everything the business does. Getting that timing wrong, either by starting work before cover is bound or by letting a policy lapse between projects, is one of the more expensive mistakes a builder can make.
The covers NSW builders most often arrange
Brokers and insurers group construction cover in slightly different ways, but most builder programs in NSW are built from the same handful of components.
Contract works and Contractors All Risk
Contract works cover responds when the project itself is damaged. That includes materials delivered to site and the partly completed structure, and it typically extends to events such as natural perils, theft and vandalism. Contractors All Risk policies wrap a broader set of construction risks into one contract, and insurers such as CGIB describe this cover as protecting projects, materials and equipment from a wide range of risks.
The sum insured matters here. A contract works limit needs to reflect the full value of the works, including materials the builder has paid for but not yet installed, because underinsuring the project leaves the shortfall with the builder.
Public liability
Public liability responds to claims for bodily injury or property damage caused to third parties in connection with your construction activities, along with related contractual liability exposures. Most builders opt for public liability cover, and it is often the first policy a head contractor asks to see before letting a subcontract. CGU reports that 94 per cent of construction companies insured with it use product and public liability cover to protect their business and projects.
Product liability
Product liability sits beside public liability and deals with loss or injury caused by something the business supplied rather than something it did on site. For a construction company that can include manufactured components, prefabricated elements or materials supplied as part of a contract. Insurers generally place product and public liability together, which is why the two are usually quoted as a pair.
Plant, tools and equipment
Excavators, scissor lifts, utes full of tools and hired equipment all represent significant capital sitting in locations you do not control. Construction policies can cover physical loss or damage to materials and equipment, and mobile plant is often arranged as its own policy with its own schedule. The important detail is listing items correctly and keeping that schedule current as the fleet changes.
Builders warranty insurance and the HBCF
Residential building work in NSW brings builders warranty insurance into the picture. The scheme, commonly known as HBCF cover, sits behind residential projects and involves eligibility checks, applications and project certificates. Eligibility is not automatic and the requirements are specific, so it pays to have an adviser check your position before you sign a residential contract rather than after.
What sits outside your construction policy
Workers compensation sits outside the policies described above and is governed by its own scheme rules, with obligations that depend on your entity structure and who you engage. Confirm your position with the relevant authority or with your broker before relying on any other policy to respond to a worker injury. Personal accident cover for principals and subcontractors is a separate conversation again.
Information to have ready before you ask for a quote
Quotes move faster when the broker can describe the business accurately the first time. Have the following ready:
- The entity structure and ABN, plus the trading name customers know you by.
- Annual turnover and the split between residential, commercial and civil work.
- The trades you self-perform and the trades you subcontract out.
- Typical project values and the largest single project you expect to run.
- Plant, tools and equipment values, including hired items.
- Claims and incident history, including anything still open.
- Contract requirements from head contractors or developers, since these often set minimum limits and wording.
What NSW projects add to the picture
Three things shape a NSW builder’s program more than anything else: the mix of residential and commercial work, the contract conditions imposed by head contractors and developers, and whether residential projects trigger builders warranty requirements. A builder doing volume residential work carries a different risk profile to one doing shopfitting or civil subcontracting, even when both have the same turnover and the same number of employees.
Where a head contractor imposes minimum liability limits or requires specific policy wording, the broker needs to see that contract before the policy is bound. Retrofitting cover after a contract is signed is more expensive and sometimes simply not possible.
Points worth checking on your own program
Construction insurance is not a set and forget product. A few things are worth reviewing each year, and each time the business changes direction:
- Whether the contract works limit still reflects the size of projects being quoted.
- Whether plant that has been sold, replaced or hired in is still listed accurately.
- Whether certificates of currency for subcontractors are current.
- Whether a change in work mix, such as moving from residential into commercial, has been disclosed to the insurer.
- Whether the liability limits still satisfy the head contractors you now work for.
How a broker changes the process
An insurance broker works for you rather than for a single insurer, which matters in a market where different underwriters treat trades, project values and claims history differently. ABS Insurance Brokers is an Australian owned brokerage based at Bankstown Airport in Sydney, arranging construction, commercial, aviation and business cover, and it also provides adjacent services including developer finance and building consultancy. On a construction program, the practical value comes from getting limits right, keeping certificates current for head contractors, and having someone to call when a claim lands on a Friday afternoon.
Frequently Asked Questions
Is construction insurance compulsory in NSW?
Some cover is driven by licensing, contract or statutory requirements and some is a commercial decision, so the answer depends on the work you do. Residential building work in NSW brings builders warranty requirements into play for eligible projects. Before you start, ask your broker which policies are required for your specific work and confirm the position with the relevant authority.
What is contract works insurance?
Contract works insurance responds to physical loss or damage to the project itself, including materials on site and the partly completed structure. A typical construction policy includes cover for materials and equipment damaged by events such as natural perils, theft and vandalism. Contractors All Risk policies broaden that protection to cover a wider range of construction risks in a single contract.
Do subcontractors need their own insurance?
Subcontractors carry their own liability exposures and head contractors usually require evidence of cover before they start. Whether you need to insure subcontractors under your own program depends on how you engage them and what your contracts say. Check certificates of currency at engagement stage and confirm with your broker whether anyone working on your projects falls outside your cover.
How much does insurance for a construction company cost?
There is no single figure. Premiums reflect turnover, the trades you perform, project values, the limits head contractors require, your claims history and the plant and equipment you own. Because those factors vary so widely between builders, the only reliable way to know your cost is to have a broker prepare a quote based on your actual business details.
