Your drawings become buildings people live in for decades. Professional Indemnity insurance protects your practice when design issues emerge, sometimes years after project completion.

Design Liability

Your designs become buildings people live and work in. A design flaw that leads to water damage, structural issues, or code non-compliance can result in substantial claims against your practice.

Long-Tail Exposure

Building defects can emerge years or even decades after construction. PI insurance with appropriate run-off provisions ensures you're protected long after a project is complete.

QUESTIONS

Frequently Asked Questions

In several Australian states, yes. Queensland requires registered building designers to hold PI insurance. Victoria's building practitioner registration also mandates cover. Even where not strictly mandatory, most clients and builders require building designers to carry PI insurance before engaging them.
The policies are similar in structure, but building designers and architects have different scopes of work and regulatory requirements. Building designers typically focus on residential and smaller commercial projects. Premiums and limits reflect these differences, though the core coverage is comparable.
Water ingress issues, structural defects, NCC non-compliance, and cost overruns from design changes are among the most frequent claims. Many claims emerge years after project completion when defects become apparent, which is why run-off cover and adequate limits are important.
This depends on your project values, state requirements, and client expectations. Many building designers carry $1-5 million. Those working on larger projects or with developer clients may need $10 million or more. We assess your typical project values to recommend appropriate limits.
Yes, if you provide design certification or compliance certificates as part of your services, claims arising from this work are typically covered. However, policy wordings vary, so we ensure your specific certification activities are explicitly included in your cover.
