Your switchboard is the heart of your home's electrical system. If it's old, crowded or missing safety switches, an electrician may recommend an upgrade, especially before adding air conditioning, an EV charger, solar or a renovation. So how much does a switchboard upgrade cost? It depends on what's there now, what you need and what the electrician finds once they open it up.
This guide explains what drives the price, signs your switchboard may need attention, and how to get quotes that are easy to compare. It applies Australia-wide, but rules differ between states, so check with your state regulator.
What's involved in a switchboard upgrade
An upgrade can range from adding safety switches to an existing board, to replacing the whole board and enclosure. It may include new circuit breakers, safety switches (RCDs), a new main switch, relabelling circuits and testing. In some cases the electrician also needs to work on the meter panel or the wiring that feeds the board.
What affects the price
The size of the job
Adding one or two safety switches to a board with room to spare is a smaller job than replacing an old fuse board entirely. The number of circuits in your home, and whether you're adding new ones, affects the parts and time needed.
The condition of your wiring
When an electrician installs safety switches, existing faults in your wiring may show up because the new protection trips. Those faults need to be found and fixed, which can add time. Ask how the electrician handles this and how it would be priced.
Asbestos in older panels
Some older switchboard and meter panels contain asbestos. The national Asbestos Product Guide says these panels are usually dark brown or black, may have a rough fibrous or wood-like surface, and were mostly installed before 1990. It warns that drilling, cutting or sanding them may release fibres. If your panel may contain asbestos, ask how the electrician will manage it safely, as this can change the method and the price.
Meter and supply work
Some upgrades also involve the meter panel, main switch or supply cables. Depending on your network, this may need coordination with your distributor, which can affect timing and cost.
Location and access
A switchboard on an outside wall with good access is simpler than one inside a cramped cupboard. Moving the board to a new location is a bigger job.
Parts and brands
Circuit breakers, safety switches and enclosures come in different brands and ranges. Ask which products are included in each quote.
Signs your switchboard may need attention
Energy Safe Victoria lists signs your wiring may be faulty in its Test. Reset. Protect. guide, including:
- old switchboards, particularly those without a safety switch
- old or broken power switches or power points
- flickering lights
- sparks from switchboards, switches or power points
Other prompts to get your switchboard checked include ceramic fuses you have to rewire, a board with no spare room for new circuits, burning smells, or a safety switch that trips often. If you see sparks, smoke or scorch marks, keep clear and call a licensed electrician straight away.
Testing your safety switches
Energy Safe Victoria recommends testing your safety switches every three months by pressing the test button, checking the power goes off on that circuit, and resetting it. If lights or appliances don't lose power, the switch may have failed and you should call a licensed electrician. Its step-by-step guide explains how.
How to get quotes you can compare
Send each electrician the same information:
- photos of your switchboard, inside and out, and the meter panel
- the age of your home, if you know it
- what you plan to add, such as air conditioning, an EV charger, solar or a renovation
- any symptoms, like tripping or flickering
- access details and your timing
Ask each quote to list the work and products included, how existing wiring faults will be handled and priced, whether asbestos is a consideration, testing, certificates, and GST.
Check licences and paperwork
Switchboard work is electrical work and must be done by a licensed electrician. Check the licence with your state regulator before work starts. Our guide on how to check a tradie's licence in every state and territory lists the official registers.
Many states require electricians to give you compliance paperwork for installation work. For example, the WA Government says you should receive an electrical safety certificate, and the SA Government says electricians must issue an electronic certificate of compliance. Ask what you'll receive in your state and keep it with your home records.
Ways to manage the cost
- Plan bigger electrical jobs together. If you're adding air conditioning or an EV charger, ask whether the switchboard work can be done at the same visit.
- Fix faults once. Ask the electrician to explain any faults found, and get a written price before extra work starts.
- Get two or three written quotes for the same scope.

Frequently asked questions
How long does a switchboard upgrade take?
It depends on the size of the board, the work involved and whether faults are found. Many jobs need the power off for part of the day. Ask your electrician for an estimate.
Do I need a switchboard upgrade to install solar or an EV charger?
Not always, but some boards don't have the space or capacity. An electrician can inspect your board and advise.
Can I add safety switches without replacing the whole board?
Sometimes, if there's room and the board is in good condition. An electrician can advise after an inspection.
How often should I test my safety switches?
Energy Safe Victoria recommends testing them every three months using the test button.
