Claims Scenarios
Situations where cover may respond.
The following are illustrative examples, not a record of actual claims. This is not an exhaustive list and whether cover responds depends on the specific policy and circumstances.
I
A cost estimate falls short
A quantity surveyor's cost estimate leaves a developer short of funding partway through a project, or a progress claim certification overpays a contractor for work not yet completed. Professional indemnity may respond to the claim that the estimate or certification was negligent.
II
A structural calculation error surfaces after construction
A structural engineer's calculation contains an error that is not discovered until after the building is complete, and rectification costs are claimed back from the engineer. Professional indemnity may respond to the claim and the cost of defending it.
III
A certification is later challenged
A building certifier issues a certificate of compliance that is later challenged after a defect is found, and the certifier is drawn into the dispute over what was inspected and approved at the time.
IV
A site inspection goes wrong
A consultant attending a site to complete an inspection is injured, or damages part of the project while there. Public liability may respond to the third party claim that follows.
Why this is different
Construction and engineering risk follows the judgement call, on and off site.
A design or measurement error is a professional judgement claim
A wrong quantity estimate, a structural miscalculation or a certificate confirming compliance with the National Construction Code issued on incomplete information does not cause an injury on its own, it causes a financial loss once the error is discovered. That is a professional indemnity exposure, distinct from anything a site incident would trigger.
Risk, and insurer appetite, varies significantly within this one category
Structural and geotechnical engineering are generally rated as higher risk than mechanical or electrical disciplines, which affects your premium. If you're a building certifier, insurer appetite has narrowed further still, following a run of cladding-related exclusions across the market. Specialist market access matters most for you.
Site attendance adds its own exposure on top of the advice
Inspecting a site, attending a progress claim assessment or reviewing work in progress puts you on someone else's property, on top of the design or measurement work itself. That combination of advisory and site-based work is what separates this category from a purely office-based professional service.

What does this typically cost?
Professional Indemnity Insurance
Professional indemnity premiums vary significantly depending on the profession, annual fee income or revenue, the limit of indemnity required and prior claims history. Lower risk professions with modest revenue can generally attract premiums from around $1,000 to $3,000 per year for standard limits. Higher risk professions, larger businesses or those with prior claims may pay substantially more.
Full cost breakdown →Public and Products Liability Insurance
The cost varies significantly depending on the nature of your business. Lower risk businesses can generally pay from around $500 to $1,000 per year for standard cover. Businesses with regular client or site interaction typically pay between $1,000 and $3,000+ annually. Higher risk occupations including construction, labour hire and events can pay well above $10,000 per year.
Full cost breakdown →Business Pack Insurance
Business pack premiums vary depending on the industry, the value of property insured, the business revenue, the sections and limits selected and the claims history. A small office or professional practice with modest contents can attract premiums from $500 to $2,500 per year. Retail, hospitality or trade businesses with larger property values and higher public liability exposure typically pay more.
Full cost breakdown →Portable Equipment Insurance
The cost of portable equipment insurance varies depending on the total value of equipment insured, the types of items and the operating environment. Lower risk equipment categories in stable operating conditions can generally attract modest premiums relative to the sum insured, for example $20,000 of laptops and cameras insured in this category might carry an annual premium of around $800 to $2,000 or more. Equipment with a higher theft or damage profile may attract higher rates.

FAQ
Questions construction and engineering consultants ask us.
Every business is different. These answers reflect general market practice. Speak with a Cipher Insurance broker for guidance specific to your situation.
Last reviewed July 2026.
What insurance do construction and engineering consultants need in Australia?
Most construction and engineering consultants carry professional indemnity insurance as the foundation. It responds to claims about your design, measurement or certification work. Public liability is commonly added for the site visits and inspections that come with the job, and a business pack plus portable equipment cover protects your practice and the equipment that travels with you.
Do I need professional indemnity insurance if I only inspect or certify, and don't design?
Yes, this is still worth having. A certification or inspection is a professional opinion that clients and third parties rely on. If that opinion turns out to be negligent, it's a professional indemnity claim, whether or not you designed the work you certified.
Does public liability cover a design or certification error?
No. Public liability responds to injury or property damage, not a financial loss from a professional opinion. A design, measurement or certification error that costs your client money is a professional indemnity claim, not a public liability one.
Are civil and structural engineers rated differently to mechanical and electrical engineers for insurance?
Yes. Structural and geotechnical engineering are generally rated higher risk than mechanical or electrical work, given the potential severity of a structural failure. That's reflected in your premium.
Is professional indemnity insurance mandatory for engineers or building certifiers?
This depends on your state and your registration type. In Queensland, engineers registered with the Board of Professional Engineers Queensland must take reasonable steps to maintain cover as a condition of registration. In Victoria, engineers endorsed under the Professional Engineers Registration Act 2019 must carry a minimum level of cover through the Victorian Building Authority. Building certifiers face similar state-based minimums. Speak with a qualified adviser about how this applies to your registration.
Why is the market for building certifier insurance considered difficult?
Cladding-related claims have led a number of insurers to introduce exclusions or step back from this class of business altogether. If you're a building certifier, that narrows your field of insurer appetite compared with most other construction consultants, which is why specialist market access matters more for you.
Does public liability cover a site inspection?
Yes. If an inspection, site visit or progress assessment leads to an injury or damage to part of the project, public liability is designed to respond to that claim.
What's the difference between professional indemnity and public liability for a construction consultant?
Professional indemnity responds when your design, measurement or certification was negligent and cost your client money. Public liability responds to injury or property damage from being on site. Most construction and engineering consultants carry both, since the work combines office-based advice with site attendance.
What is a claims-made policy and why does it matter for professional indemnity?
Professional indemnity is typically arranged on a claims-made basis. The policy in place when a claim is made and notified is the one that responds, not necessarily the policy that was current when you did the original work. That makes continuous cover, and carrying your retroactive date over between insurers, particularly important given how long a construction defect can take to surface.
How much professional indemnity cover does a construction or engineering consultant need?
This depends on the scale and value of your projects, what your contracts require and the potential cost of rectification if something went wrong. If you're a sole consultant on smaller residential projects, $1 million to $2 million may be sufficient. On larger commercial or infrastructure projects, you may need limits of $5 million to $10 million or more.
What information do I need to get a quote?
Insurers typically ask for the services you provide, the scale and value of your projects, your annual fee income or turnover, the limit of indemnity you need and your claims history. A broker can help present this information accurately to the market.
Can I get cover if I've been declined by an insurer before?
A previous decline doesn't rule out cover elsewhere. Construction and engineering consulting, particularly building certification, is a specialist area where market access varies a lot between insurers. A broker with the right panel can often place risks that a single insurer has turned down.
