Plumbers
Compare local plumbers and book online in seconds.
Plumbing is a licensed trade in every Australian state and territory, covering water supply, drainage, gas fitting, hot water systems and roof plumbing. Anyone doing plumbing work at your home must hold a current licence, and you can check it free through your state regulator, such as NSW Fair Trading, the VBA in Victoria or QBCC in Queensland.
When a hot water system dies or a drain blocks, speed matters. OneBookPlus shows you which local plumbers have availability today, lets you book without waiting on hold, and confirms the appointment instantly. Job details, quotes and invoices stay in one thread, so there is a clear record if warranty questions come up later.

List your business, freeHow to choose a good Plumber
- Verify the plumber's licence number with your state regulator before booking; every state requires one and lookups are free online.
- Check the licence covers the work you need, since gas fitting and drainage are separate classes in most states.
- Ask how call-out fees and hourly rates work, and whether after-hours jobs attract a higher rate.
- Get fixed-price quotes for defined jobs like hot water replacement, and itemised estimates for diagnostic work.
- Confirm public liability insurance and ask whether a compliance certificate will be issued where your state requires one.
- For emergencies, choose plumbers who state a realistic response window rather than a vague promise of soon.
Questions to ask before you book
- What is your licence number, and does it cover gas fitting or drainage if my job needs it?
- Is there a call-out fee, and does it come off the final bill if I go ahead?
- Can you give me a fixed price before starting, or is this charged by the hour?
- Will you supply a compliance certificate for this work if my state requires one?
- What warranty do you offer on labour, and what does the manufacturer cover on parts?
What does a plumber cost in Australia?
Most plumbers charge a call-out fee of $60 to $120, then $100 to $160 per hour, with after-hours emergencies often $200 or more just to attend. Common jobs: clearing a blocked drain $200 to $600, replacing tap washers or a mixer $80 to $250, and supplying and installing an electric hot water system $1,200 to $2,500, more for heat pump or gas. Prices vary by city and access, and quotes should show GST.
Frequently asked questions
How do I check a plumber's licence in Australia?
Every state has a free online register. Search NSW Fair Trading's licence check, the Victorian Building Authority, QBCC in Queensland, or your local equivalent, using the plumber's name or licence number. Check the licence is current and covers the class of work you need, such as gas fitting, drainage or roof plumbing. Unlicensed work can void insurance.
What counts as a plumbing emergency worth after-hours rates?
Burst pipes you cannot isolate, sewage backing up into the house, gas smells and no hot water in winter usually justify an emergency call. If you can shut off the water at the meter and contain the problem, waiting for a weekday appointment can save hundreds. Find your water meter's isolation valve before you ever need it.
Can I do any plumbing work myself?
Very little, legally. In most states DIY is limited to things like changing a washer or a showerhead without altering pipework. Anything involving water supply, drainage or gas must be done by a licensed plumber, and unlicensed work can attract fines and void your home insurance if it later causes damage.
What is a compliance certificate and when should I get one?
In most states a plumber must lodge or issue a certificate for notifiable work such as hot water installation, drainage or gas fitting, confirming the work meets the standard. Keep your copy: it proves licensed work if you sell the house or make an insurance claim. If a plumber shrugs off the paperwork, treat that as a warning sign.
Should I repair or replace an ageing hot water system?
Most storage systems last eight to twelve years. If yours is inside that window, a valve or thermostat repair can be worthwhile. Beyond it, replacement is usually better value, and rebates for heat pump systems in several states can significantly cut the cost. Ask your plumber to quote both options, including likely running costs.
