Plumbers and drainers' responsibilities
Responsibilities of a licensed plumber or drainer
Plumbers and drainers have several responsibilities for ensuring work is professional.
Licensing
Plumbing and drainage work requires a licence. There are different types of licenses depending on the type of work done.
Advertising
When a licensed corporation, partnership or individual advertises their construction service, they need to include in the advertisement their name as recorded on their licence, their licence number and for a corporation its ABN or ACN number.
Insurance
You need to show evidence of the insurance you hold to a client before providing a service. This includes advising the person that you do not have insurance if that is the case. You may ask the client to sign an acknowledgment that they have been told about your insurance arrangements. The acknowledgment must state the time and date it was given. If the client signs the acknowledgement, you must immediately give them a copy.
