From the first symptom to the completed repair
In short
Choose a plumber who services your Melbourne suburb, holds the Victorian plumbing classes needed for the work and explains the scope and charges in writing. Check their credentials through the Building and Plumbing Commission (BPC). For a suspected water-network fault, contact the retailer named on your bill first. Ask who will supervise the work and provide a compliance certificate if one is required.
Step 1
Decide whether to call a plumber or your water retailer
Look at your water bill to identify your retailer. Report a suspected network or meter fault to that provider and describe exactly where water is appearing. Do not assume a leak near the boundary belongs to the water provider.
For Yarra Valley Water customers, the retailer maintains the meter, stop tap and main-to-meter pipe in most ordinary arrangements. Pipes from the meter to the house are generally the owner's responsibility. Private extensions and shared metering can change the boundary; Yarra Valley Water can assess responsibility when the leak location is unclear.
Choose the first contact
| What you notice | Where to start |
|---|---|
| A dripping tap, leaking toilet or fault in a private pipe inside the property | A plumber with the relevant Victorian credentials. Explain the affected fixtures and when the fault occurs. |
| Water around the meter, a street leak or uncertainty about a network pipe | Your water retailer. Ask it to confirm responsibility before authorising a private repair. |
| A fault in an apartment's shared pipework or shared meter arrangement | Coordinate with the owners corporation manager and water retailer to establish access and responsibility. |
Step 2
Check the practitioner and the plumbing classes
Ask for the attending plumber's name and licence or registration number. Use the directory linked from the BPC's engaging-a-plumber page, and ask to see the photo ID card listing the work they are eligible to do. Check that their classes cover the actual job, including gas work if it is involved.
Victorian licensing and registration are different. Only a licensed plumber can issue a plumbing compliance certificate. If a registered plumber or apprentice will attend, ask which licensed plumber will supervise and take responsibility for any required certificate. Ask about relevant insurance and experience with the same kind of fault.
Step 3
Send the symptoms and access details together
Include your suburb, property type, affected fixtures, photos and when the problem started. For hot water, add a photo of the model label and describe whether the system has stopped heating, is leaking or is making an unusual noise. For a blocked drain, say which fixtures back up and whether this has happened before.
Explain access before the visit: apartment level, lift booking, parking restrictions, locked gates and any access under the house. For work requiring a tenant, landlord or owners corporation to arrange access or approve the job, identify the contact person and confirm authority to proceed.
Step 4
Compare what each quote actually includes
For planned work, give each business the same brief and request a written quote. If diagnosis is needed before a repair can be priced, ask what the assessment costs and whether you must pay it if you decline the repair. Confirm whether the repair price is a fixed quote or an estimate.
Consumer Affairs Victoria recommends checking parts, labour, travel, time spent obtaining parts, call-out fees and weekend or public holiday rates. Ask about GST where applicable, disposal and return visits. For drain work, distinguish clearing the blockage from camera inspection, pipe replacement, excavation and restoring the surface.
Agree how extra work or delays will be discussed and approved. For urgent attendance, establish the visit charge and what you are authorising on the booking call; do not delay necessary help just to collect several quotes.
Step 5
Confirm the certificate requirements and keep the records
Ask before booking whether the job requires a plumbing compliance certificate and who will issue it. BPC guidance requires one when the total work value exceeds $750, including materials, appliances, labour and GST. Include materials you supply yourself when considering that total.
Some work requires a certificate regardless of value, including installing, relocating or replacing a Type A gas appliance and constructing, installing or altering a below-ground sanitary drain. The BPC page lists the other categories. Complex gas installations have a separate process, so ask the plumber which requirements apply.
Where required, the licensed plumber must give you the certificate within five days of completing the work or termination of the plumbing contract. Keep it with the accepted quote, approved changes, invoice and any fault report. Ask the plumber to explain what was fixed and any follow-up work still needed.
