What Does Professional Indemnity Insurance Cover?

Contractor professional indemnity insurance helps protect you if a client claims your advice, plans, drawings, specifications, or project recommendations caused them financial loss.

This is especially relevant for contractors who design, certify, consult, manage projects, or provide technical guidance as part of their work.

Cover is subject to policy terms, conditions, limits, and exclusions, but may include:

If a client alleges your advice or documentation caused them loss, this cover may respond to claims such as:

  • Errors in plans, drawings, or specifications
  • Incorrect measurements or calculations
  • Omissions in reports or scope documents
  • Advice that results in rework or financial loss

Where your contract sets out professional responsibilities, cover may assist with claims involving:

  • Alleged failure to meet agreed specifications
  • Claims that work did not meet regulatory standards
  • Disputes relating to professional obligations under a service agreement

If issues arise from your professional communications, cover may include:

  • Alleged defamation in reports or correspondence
  • Claims relating to statements made in professional documentation
  • Disputes connected to written or verbal professional advice

Even if a claim is not proven, legal costs can be significant. This cover may assist with:

  • Legal representation and defence costs
  • Investigation expenses
  • Costs associated with responding to formal complaints

If a client alleges they relied on information you provided, your cover may respond to:

  • Claims relating to quotes, tenders, or capability statements
  • Allegations of incorrect or incomplete project information
  • Disputes over representations made in professional advice

If you retire or close your business, run-off cover may help protect you against:

  • Claims made after you stop trading
  • Allegations relating to past projects or advice
  • Delayed financial loss claims linked to previous work

Professional indemnity insurance is designed to respond to civil liability arising from professional services. It does not cover every type of risk. Common exclusions may include:

  • Claims arising from physical injury or property damage, which are typically covered under public liability insurance
  • Intentional, dishonest, fraudulent, or criminal acts
  • Known claims or circumstances that existed before the policy start date
  • Fines, penalties, or punitive damages where excluded by law or policy terms
  • Contractual liabilities that go beyond your normal professional duty
  • Work performed outside the scope of the insured professional services
  • Claims arising after cancellation where no run-off cover is in place

Important note: Cover is subject to policy wording, conditions, limits, and exclusions. Specific exclusions can vary between insurers and occupations.

How Much Does Professional Indemnity Insurance Cost?

Public liability insurance costs vary depending on the type of work you do, your turnover, the number of workers you have, and the level of cover you choose. Higher-risk trades and larger contracts typically attract higher premiums, while lower-risk sole traders may pay less.

For example, a sole trader working in residential settings may pay less than a contractor working on commercial construction sites with staff. The level of cover selected will also affect the cost.

Other factors that can influence your premium include:

  • Your claims history
  • The type of clients you work with
  • Subcontractor use
  • Annual revenue
  • The locations where you operate

FAQs

Professional indemnity insurance protects contractors if a client claims your advice, design, certification, or professional service caused them financial loss.

It can assist with legal defence costs and compensation claims arising from alleged negligence, errors, omissions, misleading statements, or breaches of professional duty. Cover is subject to policy terms, conditions, limits, and exclusions.

No. Professional indemnity insurance and public liability insurance cover different risks.

Public liability covers third-party injury or property damage caused by your work. Professional indemnity insurance covers financial loss arising from advice, design, or professional services. Many contractors require both, depending on the type of work they perform.

Professional indemnity insurance is not compulsory for every contractor.

However, it may be mandatory if you are registered under certain licensing schemes, belong to a professional body, or enter contracts that require it. Many commercial and government contracts specify minimum professional indemnity limits.

You may need professional indemnity insurance if clients rely on your advice, reports, drawings, specifications, or certifications.

If you provide consulting, design input, project management, or compliance sign-offs, you are exposed to financial loss claims. Even if it is not legally required, it is often expected in commercial contracts.

It may be beneficial, as sole traders can still face professional liability claims.

Your business structure does not prevent a client from pursuing compensation if they suffer financial loss due to alleged professional error or negligent advice. Sole traders providing consultancy, design, or certification services often require professional indemnity insurance.

Some builders require professional indemnity insurance, particularly if they provide design services or operate under design and construct contracts.

If you are responsible for plans, specifications, engineering input, or certification, professional indemnity insurance may be required by contract or licensing authorities.

Most electricians primarily require public liability insurance.

However, electricians who provide design advice, issue compliance certifications, perform consultancy work, or undertake design and construct contracts may also require professional indemnity insurance.

Plumbers generally require public liability insurance.

Professional indemnity insurance may be necessary if you provide design advice, hydraulic consulting, engineering input, compliance certifications, or specialist consultancy services.

Professional indemnity policies are typically written on a claims-made basis.

No, professional indemnity insurance premiums in Australia typically include GST.

Insurers generally charge GST on the premium, and this will appear on your tax invoice.

If you receive a complaint, demand letter, or become aware of a potential claim, you should notify your insurer as soon as possible.

Professional indemnity insurance operates on a claims-made basis, which means claims must be notified during the policy period. Delays in reporting can affect how a claim is handled.

The general steps are:

  1. Notify us immediately once you become aware of a claim or circumstance
  2. Provide copies of contracts, correspondence, reports, or relevant documents
  3. Do not admit liability or agree to settle without insurer approval
  4. Cooperate with the appointed legal or claims team

We guide contractors through the process and help liaise with the insurer. Claims are assessed subject to policy terms, conditions, limits, and exclusions.

Yes. Professional Indemnity Insurance can usually be cancelled if it is no longer required. Refunds depend on the insurer, how long the policy has been active, and whether any claims have been made.
