A kitchen renovation in Melbourne involves more than choosing benchtops and cabinet colours. Older weatherboard and California bungalow homes often have kitchen plumbing that wasn’t built for modern appliances. Renovating one of these kitchens usually means rerouting that plumbing first.
Once the new appliances arrive, the common question is: who is qualified to install each appliance?
Some appliances need a licensed plumber. Others need a gas fitter or electrician. And a few you can handle yourself without breaking any rules. This guide breaks down the requirements for every common kitchen appliance so you can plan your trades, avoid delays, and stay on the right side of Victorian regulations.
Why Kitchen Renovations Need Different Trades
In Victoria, plumbing, gas fitting and electrical work are each regulated under separate licensing systems. The Victorian Building and Plumbing Commission (BPC) oversees plumbing and gas fitting licences, while Energy Safe Victoria regulates gas safety standards across the state.
This means a single kitchen renovation in Melbourne can require three different licensed tradespeople depending on the appliances being installed:
- A plumber handles water supply and drainage connections
- A gas fitter manages gas line work
- An electrician takes care of new circuits or hardwired fittings
Hiring a licensed tradesperson for your kitchen renovation protects you well beyond just ticking a compliance box. If plumbing work is valued at more than $750 (including materials, appliances, labour and GST), the plumber must issue a compliance certificate confirming the work meets the relevant codes and standards. That certificate protects you if something goes wrong down the track.
Kitchen Appliance Connections That Need a Licensed Plumber
Any appliance that connects to your home’s water supply or drainage system requires a licensed plumber under Victorian regulations. In a kitchen renovation, two connections usually need one: the water and drain lines for a freestanding or integrated dishwasher and the water line for a fridge with a water dispenser or ice maker.
Dishwasher Water and Drain Connections
Dishwasher installation needs both a cold water supply line and a drain connection to your kitchen’s waste pipe. These are regulated plumbing connections that only a licensed practitioner can legally make.
If you are replacing a dishwasher in the same position with existing plumbing points already in place, the job is relatively quick. But if your kitchen renovation in Melbourne involves relocating the dishwasher, the plumber will need to extend or reroute the water supply and drainage lines to the new spot.
A dishwasher installation plumber will also check that backflow prevention is in place, connections are watertight, and drainage falls correctly to avoid pooling water.
Fridge and Ice Maker Water Lines
Many modern fridges include water dispensers or built-in ice makers that require a dedicated water line. This involves tapping into the kitchen’s cold water supply, which is classified as regulated plumbing work in Victoria.
A fridge water line plumber will install a tee connection on the nearest cold water pipe, run food-grade tubing to the fridge location, and pressure-test the line for leaks. It sounds like a small job, but getting it wrong can cause slow leaks behind the fridge that go unnoticed for months and lead to serious water damage.
When to Call a Gas Fitter or Electrician
Range Hoods Over Gas Cooktops
A range hood sitting above a gas cooktop can involve two separate trades. The hood itself may need an electrician for hardwiring, while the gas cooktop underneath requires a licensed gas fitter to connect it to the supply line.
Under Victorian law, all gas appliance work must be carried out by a licensed gas fitter. After installing the gas cooktop, they must give you a compliance certificate confirming the work is safe. If you are switching from electric to gas as part of your kitchen renovation in Melbourne, gas fitter range hood installation work will also include running new gas piping to the cooktop location.
Microwave Power Circuits
Most microwaves plug into a standard power point and need no tradesperson at all. But a built-in or integrated microwave installed as part of a renovation often tells a different story.
Do you need an electrician for a microwave? If the unit requires a new circuit from the switchboard or needs to be hardwired into cabinetry, the answer is yes. Only a licensed electrician can run new circuits or modify existing wiring in Victoria. If your microwave simply plugs into an existing outlet, no electrician is needed.
What Homeowners Can Legally Install Themselves
Plumbing maintenance that homeowners can legally carry out is generally limited to small jobs, such as fixing a leaking tap — anything beyond that, including swapping fittings or working on internal plumbing components, falls under licensed plumbing work.
In the kitchen, washing machine hose installation is a DIY task when you are connecting the supplied rubber hoses to existing isolation valves. You are not modifying the plumbing system, just attaching hoses to taps that are already in place.
Freestanding appliances that only need a standard power point, such as a plug-in oven, can be positioned and plugged in without a tradesperson, provided no new plumbing, gas or electrical work is involved.
The key rule is simple: if the task involves cutting into water pipes, connecting to drainage, working on gas lines, or running new electrical wiring, you need a licensed professional.
