How Much Does Professional Indemnity Insurance Cost in Australia?
The cost of Professional Indemnity Insurance in Australia varies significantly. There is no single price because insurers assess the specific professional risk created by your business, the services you provide, your clients, your revenue, your claims history and the amount of cover you require.
A sole consultant with straightforward services and modest turnover may have a very different PI Insurance premium from an engineering firm, mortgage broking business, architecture practice, IT provider or professional services company working on high-value contracts.
The most accurate way to establish the cost of Professional Indemnity Insurance is to obtain a tailored quote based on your actual business activities.

What affects the cost of Professional Indemnity Insurance?
Insurers generally consider several key factors when calculating a PI Insurance premium.
Your profession and services
The type of work you do is central to the cost of Professional Indemnity Insurance. Professionals who provide high-value advice, technical designs, financial services, complex reports, regulated services or work that can cause substantial client loss may face higher premiums than lower-risk service providers.
It is important to accurately describe all services you provide. Understating your activities may result in a cheaper quote, but it can create significant problems if a claim later arises from work that was not properly disclosed or covered.
Annual turnover and fee income
Revenue and professional fees are commonly used as an indicator of exposure. Higher turnover can mean more clients, larger projects, increased reliance on your services and a greater chance of a claim.
However, turnover is not the only consideration. A business with modest revenue can still have a high liability exposure if it works on major projects or provides advice that affects large financial decisions.
Your PI Insurance limit
The higher the limit of indemnity, the more the policy may cost. Common PI limits include $1 million, $2 million, $5 million, $10 million and higher.
The appropriate limit should reflect your real exposure and contracts—not simply the cheapest available option. Consider the largest potential financial loss a client could allege, your contractual obligations and whether legal defence costs reduce the limit.
Your excess
The excess is the amount you may need to contribute towards a claim. Choosing a higher excess can sometimes reduce the premium, but it also increases the amount your business may need to pay if a claim occurs.
An excess should be selected based on what the business can realistically afford, not simply to achieve the lowest annual premium.
Claims history and known circumstances
Past claims, complaints, disputes and notified circumstances can affect the availability and price of cover. Insurers may also consider whether the business has robust risk-management practices, clear client contracts, quality-control processes and reliable documentation.
If you are aware of a circumstance that could reasonably lead to a claim, it should be disclosed in accordance with your policy and insurer requirements.
Your clients, contracts and project values
Working with large corporates, government entities, property developers, financial institutions or high-value clients can increase potential exposure. Insurers may review:
Your largest client and project values
The scope of your work
Contractual indemnities and liability clauses
Whether you work overseas
Whether you use subcontractors
Whether you provide design, certification, regulatory or financial advice
Whether one issue could affect several clients
A low professional fee does not necessarily mean low liability. A small error can sometimes create a much larger client loss.
Your retroactive date and past work
Professional Indemnity Insurance is commonly claims-made insurance. Your retroactive date determines how far back your current policy may cover professional services you performed in the past.
A longer history of prior work can influence the insurer’s assessment of risk. Maintaining continuous cover is important when changing insurers or renewing PI Insurance, as a gap may affect protection for historical work.
Why the cheapest PI Insurance quote is not always the best option
A low premium can be appealing, but the policy needs to respond to the work your business actually does. Before purchasing PI Insurance, compare more than price.
Check:
The declared professional services
The limit per claim and aggregate limit
Whether legal defence costs are inclusive or additional to the limit
The excess
The retroactive date
Major exclusions and sub-limits
Cover for employees, subcontractors and prior entities
Contractual liability provisions
Claims-made notification requirements
Whether run-off cover may be required when you retire, sell or close the business
