Professional indemnity for architects and engineers

Design professionals carry the longest tail in insurance: a drawing issued today can be the subject of a claim a decade on. In NSW, registered design practitioners and professional engineers on regulated buildings must hold professional indemnity cover. Here is what the policy does, what NSW requires, and how to compare quotes.

What professional indemnity does for a design practice

Professional indemnity covers claims that your design, specification, certification or advice caused a client or third party a loss, and pays the legal costs of defending them. For architects and engineers the exposures are structural failure, defective design, non-compliant documentation, cost overruns blamed on the design, and contract administration. Public liability sits alongside it for injury and property damage on site visits and at your office.

The policy is claims-made: the policy in force when the claim is made responds, not the one in force when the drawings were issued. That makes continuous cover, and run-off cover when you retire or close, essential.

What NSW requires

NSW regulates design and engineering work on class 2, 3 and 9c buildings under the Design and Building Practitioners Act 2020.

What NSW requires
PractitionerRequirementSince
Registered design practitionersAll design work must be covered by a professional indemnity policy, including liability from when the practitioner first became registered1 July 2022
Registered professional engineersA policy giving an adequate level of cover for their engineering work on regulated buildings, or an approved alternative arrangement1 July 2022
Registered building practitionersNSW’s insurance page says they must also be indemnified for their building workFrom 1 July 2027, per NSW

A practitioner who claims to be insured when they aren’t faces penalties, and the regulator can ask for proof of insurance as a condition of registration. Other states run their own engineer registration schemes; a broker checks what applies to you.
