Waterproofers: public liability requirements in Western Australia

Verified for Western Australia

• Licence liability condition: No trade licence exists to carry a condition. Home indemnity insurance applies to residential building work above its threshold, through whoever holds the builder registration for the job. WA · effective 2026-08-24 Consumer Protection WA · 2026-08-13
• Licence evidence required: Nothing for the trade itself. WA · effective 2026-08-24 Consumer Protection WA · 2026-08-13
• Licensing body: Not separately registered as a trade in Western Australia on the guidance located. WA registers builders, painters, electricians and plumbers; other trades fall under builder registration where the work is contracted above the threshold rather than holding a licence of their own. Recorded against published guidance; the full registration regulations could not be retrieved, so treat this as "no separate registration is published" rather than a certainty.

What contracts commonly ask for

Principals and head contractors set their own insurance requirements, and those are frequently higher than a licence condition. The requirement that binds is the higher of the two, and both have to be read from the actual document.

• What the limit figure on a certificate means
• Cover for the principal for your work
• When a certificate falls short of the contract

What this cover costs

This site publishes no cost benchmark for this cover. A benchmark needs a real sample of documents, and none is published until the sample is large enough to compute a median honestly. A benchmark from a handful of policies is a guess with a decimal point.
