Choosing a plumber in Sydney
In NSW, plumbing work must be done by a licensed plumber, and a few simple checks protect you from poor work and disputes. This page explains what to check before you hire, whether it's a leaking tap or a bathroom renovation.

The guide
The main things to understand.
Check the licence
Plumbing work in NSW must be carried out by a licensed or supervised plumber. You can check a licence, its class and any conditions with NSW Fair Trading's online licence check.
Get written quotes
For anything beyond a small repair, get written quotes that describe the work, materials, call-out fees, hourly rates and whether GST is included.
Contracts and insurance for larger jobs
Larger residential jobs need a written contract, and above a set value the builder or tradesperson must provide home building compensation cover. NSW Fair Trading explains the current thresholds.
Compliance certificates
For most plumbing and drainage work, the plumber must lodge a certificate of compliance and give you a copy. Keep it with your property records.
Emergencies
For burst pipes, turn off the water at the main. Ask emergency plumbers about after-hours call-out fees before they come, and for a written quote once the problem is found.
Water authority work
Work connected to Sydney Water's network, such as new connections, may need approval through Sydney Water's processes.
