Selecting a contractor

Who's doing your plumbing?

It is important to ensure the right people with the right qualifications and practical experience are performing your plumbing work. By engaging a licensed plumber and/or drainer you minimise unnecessary risks to your family's health and safety.  

What licence should a plumber hold?

In some instances, it may be necessary for a plumber to hold both an occupational and contractor licence to carry out work, regardless of the value. An occupational licence enables the person to physically carry out the work, a contractor licence allows the person to engage in a contract for the work. To find out more about a licensee you can use our online licensee search, or search for an occupational licence.
