What Our Clients Say
Signs You Need a Switchboard Upgrade
Most Melbourne homes built before the 1990s have switchboards that were never designed to handle the electrical demands of a modern household. Air conditioning, EV chargers, solar inverters, home theatre systems, induction cooktops, and multiple high-draw appliances all put sustained pressure on a system that was built for a simpler time. Some of the clearest signs it is time for an assessment:
Your switchboard still has ceramic fuses or rewirable fuse wire rather than circuit breakers
Circuits trip regularly or fuses blow without an obvious cause
You are adding an EV charger, solar system, air conditioner, or any high-draw appliance
Your property is being renovated, extended, or converted and the electrical load is increasing
You notice flickering lights, a burning smell near the board, or discolouration around switches or fuses
A licensed inspection has flagged your board as non-compliant or inadequate
Your switchboard has an asbestos backing panel, common in homes built before the mid-1980s
You are buying or selling a property and want the electrical system properly assessed
If any of these apply, an assessment is worth scheduling before the problem develops into something more serious or more expensive.
Switchboard Upgrade Services
We handle the full range of switchboard and mains work for residential, commercial, and strata properties across Melbourne's north east.
Mains Upgrades and Network Distributor Work
Mains work is an area where many electricians refer out or decline to quote. Bitz Electrical handles it directly. If your property needs its consumer mains upgraded, we manage the full process including the required notification to AusNet Services (the network distributor for Melbourne's north east), the physical upgrade of the mains cable, and reconnection.
Mains upgrades are required in a number of situations:
The existing mains cable is undersized for the proposed electrical load
The cable insulation has deteriorated due to age or UV exposure on the service mast
Three-phase supply is being introduced to a property currently on single-phase
The metering arrangement is being reconfigured as part of a solar or battery installation
The property is being subdivided and a new supply point is required
AusNet Services work, including changes to the service fuse or network connection point, must be coordinated through a licensed electrician with the relevant accreditation. We handle this on your behalf so the job does not stall waiting for distributor involvement.
Why an Outdated Switchboard Is a Risk Worth Taking Seriously
Old ceramic fuse boards are one of the leading causes of residential electrical fires in Australia. The mechanism is straightforward: ceramic fuses do not trip automatically when a fault occurs. They rely on a fuse wire that melts under excessive load. When that wire blows, the correct response is to replace it with the right rated wire. In practice, many older boards have had incorrect fuse wire installed over the years, sometimes heavier gauge wire that simply will not melt, which removes the only protection the circuit has.
Beyond fire risk, older boards are typically not capable of supporting the sustained loads of a modern household. Running a 6kW reverse-cycle air conditioner, a 7kW EV charger, and an induction cooktop simultaneously on a board designed for a 1970s home creates sustained overloading of wiring inside walls. This heat builds over time and is a hidden hazard that can go undetected for years before causing a fault.
A modern switchboard with appropriately rated circuit breakers and RCBOs on every circuit responds to faults in milliseconds, handles increased electrical loads safely, and gives you the documentation your insurer needs to confirm the property's electrical system is compliant.
The Asbestos Factor in Pre-1985 Melbourne Homes
Homes built before the mid-1980s across Melbourne's north east, particularly the 1960s and 1970s brick veneer stock common in Doncaster, Templestowe, Warrandyte, and Donvale, frequently have asbestos cement switchboard backing panels. This is not an immediate hazard when undisturbed, but it is a reason to use a licensed electrician who understands the handling requirements rather than attempting any DIY work near the board.

Switchboard Upgrade Cost in Melbourne
Most residential switchboard upgrades in Melbourne's north east fall in the following ranges. The main variables are the number of circuits, whether a mains upgrade is required, whether asbestos disposal is involved, and whether the property is single-phase or three-phase.
These are indicative ranges only. Three-phase upgrade costs vary significantly depending on the size of the board, condition of existing mains, and whether distributor coordination is required. We provide a written quote after assessing your property, with no variations on the day. Call 1300 215 193 or use the form below.

Switchboard Upgrade FAQs
What is a switchboard upgrade?
A switchboard upgrade replaces your existing board and its components with a modern unit built to current Australian wiring standards. In most cases this means removing old ceramic fuses or an outdated board and installing new circuit breakers and safety switches, along with a correctly rated main switch and clear circuit labelling. The result is a board that protects your home and the people in it far more effectively than older equipment.
How do I know if my switchboard needs upgrading?
Common signs include ceramic or rewireable fuses, a board with no safety switches, breakers that trip often, flickering lights, a burning smell or scorch marks near the board, or a board that is full with no room for new circuits. Homes built before the 1990s often still have original boards that no longer meet current standards. If you are planning solar, an EV charger, air conditioning or a renovation, an upgrade is often needed to support the extra load.
How much does a switchboard upgrade cost?
The cost depends on the size and condition of your existing board, the number of circuits, whether asbestos is present, and whether the main supply needs any work. Because every board is different, we provide a written quote after assessing yours so you know the full cost before we begin. Our quotes carry no variations, so the figure you approve is the figure you pay.
How long does a switchboard upgrade take?
A straightforward domestic switchboard upgrade is usually completed within a single day. Larger boards, three phase supplies, asbestos removal or additional rewiring can take longer. We give you a clear timeframe as part of your written quote.
Will my power be off during the upgrade?
Yes. The power needs to be switched off while we work on the board, for safety reasons. We plan the work to keep the outage as short as possible and let you know the expected timeframe in advance so you can prepare.
What are safety switches and does my home need them?
Safety switches, also known as RCDs, cut the power in a fraction of a second when they detect a fault, which helps prevent electric shock and electrical fires. Current standards require safety switches on power and lighting circuits, and we fit them as standard on every board we upgrade. Many older boards have none, which is one of the most common reasons an upgrade is recommended.
Do I need to replace my ceramic fuses?
Ceramic and rewireable fuses are an older technology that offers far less protection than modern circuit breakers and safety switches. They are no longer installed in new work and do not provide the fault protection that current standards call for. Replacing them with modern breakers and RCDs is a core part of most switchboard upgrades.
My switchboard has asbestos. Can you still upgrade it?
Yes. Many boards from the 1960s to the 1980s have asbestos backing panels. We are experienced in handling these safely and arrange for the material to be removed and disposed of correctly before the new board is installed. If asbestos is found during assessment, it is accounted for in your written quote.
Will I receive a Certificate of Electrical Safety?
Yes. On completion we provide a Certificate of Electrical Safety, which confirms the work has been carried out and tested to Australian standards. It is worth keeping with your records, as it can be important for insurance and any future sale of your home.
Do I need a switchboard upgrade for solar or an EV charger?
Often, yes. Solar systems and EV chargers add load and need correct protection, and in many cases extra space on the board. If your existing board is full or has no safety switches, an upgrade is usually needed before the new equipment can be connected safely and to standard.
Are you licensed and insured?
Yes. Bitz Electrical holds REC Licence 31813 and is a member of Master Electricians Australia. All work is carried out by fully licensed electricians and backed by our lifetime workmanship guarantee.
