This is a general information site for Australian home owners. Each guide below explains what a job usually involves, the signs that tell you it might be needed, and the questions worth asking the licensed tradesperson you hire.
When you know roughly what a job involves, the conversation with a licensed tradesperson is shorter, the quotes are easier to compare, and you are less likely to be sold work your home does not need.
These guides are written in plain language for home owners. They do not replace an on site assessment by a licensed tradesperson who has actually looked at your property. Use them to get your bearings, then get more than one quote and compare them line by line.
This covers the fixed wiring of your home: switchboards, rewiring older properties, safety switches, and three phase supply. It is the category most home owners bump into first, usually through a switchboard that is out of room or a circuit that keeps tripping.
A switchboard upgrade typically means a new enclosure with safety switches protecting the circuits. Rewiring means replacing old cable throughout the home, which is invasive and depends on roof and wall access. Three phase supply relates to how power is delivered to the property and what equipment can run from it. All of this is fixed wiring work carried out by a licensed electrician.
Solar panels and home batteries are a common upgrade, and the parts most people underestimate are the site assessment and the wiring between the equipment and the rest of the home.
Panels are mounted on the roof, connected through an inverter, and wired into your switchboard. A battery stores what the panels generate so you can use it later. The job usually includes mounting, cabling, an inverter, a connection to your board, and paperwork at the end. Roof condition, shading and the age of your switchboard all affect the plan.
Air conditioning is part installation, part electrical work. The unit itself is only one piece of the job; the position, the electrical supply and the drainage all matter.
A split system has an indoor unit and an outdoor unit connected by pipework and cabling. The installer positions both, runs the pipework, and provides a dedicated electrical supply. Larger or multi room systems may need more supply capacity. Ducted systems add ductwork through the roof or under the floor.
Roof work covers a wide range, from patching a leak to restoring an ageing roof to a full replacement. The right answer depends on the condition of the roof and what is underneath it.
A repair deals with a specific problem such as a cracked tile, a failed flashing or a damaged section of sheet roofing. Restoration usually means cleaning, treating and recoating an existing roof to extend its life. Replacement means removing the old covering and installing a new one, and often includes checking the battens, insulation and roof sarking while the roof is open.
Birds nesting under solar panels are a common problem. They build nests in the gap between the panels and the roof, which can lead to mess, noise and damage to cabling over time. Meshing closes that gap.
A coated wire mesh is fitted around the perimeter of the array to stop birds getting underneath, fixed so it follows the shape of the panels and the roof. The installers need to work safely at height and take care not to disturb the panels, the mounting or the wiring while fitting it.
A single lump sum tells you very little. Ask for labour, materials and testing listed separately, with any allowance for unknown conditions written down rather than left implied.
Ask for the name and licence number of the person responsible, and check it yourself against the relevant state register before work starts.
Agree in advance who patches walls, ceilings or roofing once the work is done. Many quotes stop at making the area safe, not at restoring the surface.
Adding a new circuit, a solar system or air conditioning can put pressure on a switchboard that is already full. Ask whether the board needs attention before the new work goes in.
Start with the guide closest to your situation. Each one is written to be read in a few minutes.
The resources page translates the terms that get thrown around in quotes so nothing catches you by surprise.
Go into the conversation with the questions from the guide and the quotes get much easier to compare.
Yes. Electrical work, solar and battery installation, air conditioning installs and roofing should all be carried out by a licensed tradesperson in the relevant field. Ask for the licence and check it against your state register before work begins.
Each state and territory has a public register of licensed trades. Search by name or licence number, and make sure the scope on the licence matches the job you are having done.
Usually it comes down to different assumptions about access, different quality of materials, and whether testing and certificates are included or added afterwards. Compare the line items, not just the total.
Some minor tasks are permitted for home owners in some states, but anything involving fixed wiring, new circuits, the switchboard, roofing at height or solar equipment should go to a licensed tradesperson. Check what applies where you live.
