Professional Indemnity Insurance Explained

If a client claims your advice cost them money, PI cover pays your defence costs and damages.

Professional Indemnity (PI) insurance protects you when a client claims that your professional advice, service, or expertise caused them financial loss. It covers your legal defence costs and any damages awarded — even if the claim has no merit.

Who needs PI insurance?

  • Management consultants and business advisers: If a client claims your strategy cost them revenue, you're exposed.
  • IT professionals and developers: A system failure or data breach traced to your code can generate a significant claim.
  • Designers and architects: Design errors that result in construction issues or brand damage are classic PI claims.
  • Financial advisers: Required by ASIC for licensed advisers.
  • Accountants and lawyers: Required by professional associations; exposure is high.
  • Healthcare professionals: Medical indemnity is a specific form of PI.

Key features to check

  • Retroactive date: PI policies are 'claims-made' — the policy in force when the claim is made (not when the work was done) responds. Retroactive cover protects you for past work.
  • Run-off cover: If you stop practising, you need run-off cover for claims that arise after you close — sometimes for years.
  • Defence costs: Check whether defence costs are inside or outside the limit. Outside is better — it means your full limit is available for damages, not eaten by legal fees.

Note

PI premium is heavily occupation-dependent. A management consultant and a building designer may both get $1M PI cover, but the premiums can differ by 3–5×.
