Switchboard Replacement Price Ranges in Melbourne

Every home is different, so there is no single price for a switchboard upgrade. The cost depends on the size of your home, the number of circuits, the type of power supply, and the condition of your existing installation. That said, here are the typical price ranges we work within for residential switchboard replacements across Melbourne.

Basic Single Phase Switchboard Upgrade: $1,800 to $2,400

This is the entry point for a switchboard replacement on a smaller home or apartment with a single phase power supply and a modest number of circuits, typically up to 8 or 10 circuits. This covers removing the old switchboard, installing a new enclosure, fitting modern circuit breakers and safety switches (RCDs), labelling all circuits, and issuing a Certificate of Electrical Safety. This type of upgrade is common in one or two bedroom apartments and smaller homes across Melbourne’s inner suburbs.

Standard Home Switchboard Upgrade: $2,500 to $3,500

This is the most common range for a typical Melbourne home, covering 3 to 4 bedroom houses with single phase power, 12 to 20 circuits, and the inclusion of RCBOs (combined RCD and circuit breaker devices) on individual circuits, plus surge protection. Most homes we work on in suburbs like Richmond, Hawthorn, Brunswick, and Williamstown fall into this range. This price typically includes a new switchboard enclosure, individual RCBOs for each circuit, a main switch upgrade, surge protection, full circuit labelling, a compliance certificate, and a thorough cleanup.

Complex, Large, or Three Phase Upgrades: $4,000 to $5,500+

Larger homes, properties with three phase power supplies, or installations with complicating factors will sit in this range or above. Three phase switchboards are physically larger, require more components, and take longer to install. Homes with 20 or more circuits, multiple sub boards, or those needing meter relocations or supply upgrades will also be at the higher end. We regularly see these costs on larger homes in Toorak, Kew, Canterbury, and Brighton where the homes are substantial and the electrical systems match.

Properties that require asbestos removal around the meter or switchboard, or homes where the supply cable from the street needs to be upgraded to handle increased loads, can push costs above $5,500. These are less common but worth being aware of, especially in homes built during the 1960s and 70s when asbestos backing boards were commonly used in switchboard installations.

What Factors Affect the Cost of a Switchboard Replacement?

Single Phase vs Three Phase Power

Most residential homes in Melbourne run on single phase power, which is a single active conductor supplying 230 volts. Some larger homes, particularly those with ducted air conditioning, workshop equipment, or electric vehicle chargers, have three phase power, which provides three active conductors and 415 volts between phases. A three phase switchboard is more complex, uses more components, and costs more to install. If you are not sure whether your home is single or three phase, your electrician can tell you when they inspect the existing setup.

Number of Circuits

More circuits means more circuit breakers or RCBOs, a larger switchboard enclosure, and more time to install and test everything. A small apartment might have 6 to 8 circuits, while a large family home could have 20 to 30 or more. Each additional circuit adds to the cost in components and labour.

RCDs vs RCBOs

There are two main approaches to protecting circuits with safety switches. The first is to use a small number of RCDs, each protecting a group of circuits. The second is to use individual RCBOs on each circuit, where each device combines a safety switch and a circuit breaker in one unit. RCBOs are the premium option, and for good reason. If one circuit develops a fault, only that circuit trips, and everything else stays on. With grouped RCDs, a fault on one circuit can take out multiple circuits at once. RCBOs cost more per device, but we recommend them for the convenience and safety they provide.

Meter Relocation

Sometimes the electricity meter needs to be relocated as part of a switchboard upgrade, particularly if the current meter position does not comply with current standards or if the property is being renovated. Meter relocations involve coordination with your electricity distributor, which in Melbourne is usually CitiPower, Powercor, Jemena, or United Energy depending on your location. This adds both cost and time to the project. Your distributor may also need to upgrade the service fuse or supply cable, which can add further cost.

Asbestos

Many switchboards installed in Melbourne homes between the 1950s and 1980s used asbestos backing boards or asbestos cement sheets as part of the installation. If asbestos is present, it needs to be safely removed by a licensed asbestos removalist before the new switchboard can be installed. This adds to the cost and can also add a few days to the project timeline depending on the removalist’s availability. We handle the coordination of asbestos removal for our customers so you do not have to organise a separate tradesperson.

Condition of Existing Wiring

When we remove an old switchboard, we sometimes find that the wiring coming into the board is in poor condition. Cables may be damaged, undersized, or poorly terminated. If wiring needs to be extended, replaced, or re terminated, this adds time and cost. In older Melbourne homes, particularly those with original rubber and cloth wiring from the 1940s and 50s, the wiring at the switchboard may need attention as part of the upgrade.

Compliance Upgrades

When we replace a switchboard, the new installation must comply with current Australian Standards (AS/NZS 3000, the Wiring Rules) and Victorian electrical safety regulations. In some cases, this means bringing other parts of the installation up to current standards. For example, if your home does not have adequate earthing, we may need to install new earth electrodes. If the main earth conductor is undersized, it may need to be upgraded. These additional works are sometimes required to obtain the Certificate of Electrical Safety and ensure your installation is safe and compliant.

Old Ceramic Fuse Switchboard vs Modern Switchboard

If you are still weighing up whether to upgrade, here is a straightforward comparison of what you have now versus what you would get.

Ceramic Fuse Board

• No safety switches (RCDs) to protect against electric shock
• Rewirable fuse wire that can be replaced with incorrect ratings
• Ceramic fuse holders that can crack and overheat
• Often mounted on a wooden backing that is a fire risk
• No surge protection
• Limited number of circuits, often insufficient for modern needs
• No circuit labelling in many cases
• Cannot be expanded easily to add new circuits

Modern Switchboard

• Safety switches (RCDs or RCBOs) on every circuit for shock protection
• Circuit breakers that trip reliably and can be reset without replacing fuse wire
• Non combustible enclosure rated for the application
• Surge protection to safeguard appliances and electronics
• Clear circuit labelling for easy identification
• Capacity to add additional circuits for future needs such as EV chargers, air conditioning, or home office setups
• Compliant with current Australian Standards and Victorian regulations
• Issued with a Certificate of Electrical Safety

Why Going With the Cheapest Quote Is Not Always Smart

We get it. When you are getting quotes for a switchboard replacement, it is tempting to go with the lowest number. But with electrical work, the cheapest option can end up costing you more in the long run, or worse, putting your family at risk.

Here is what to watch out for with very low quotes. Some operators use budget components that do not last. Others cut corners on workmanship, leaving connections that are not properly torqued, wiring that is not neatly run, or circuit labelling that is vague or missing. A few do not include a Certificate of Electrical Safety in the price, which is a legal requirement in Victoria for prescribed electrical work.

We have been called out to “fix” switchboards that were installed by others at a low price point, and the workmanship has been concerning. Loose connections, overcrowded enclosures, missing cable glands, and inadequate earthing are things we have seen more than once. A switchboard should last 25 to 30 years or more, so it is worth getting it done properly the first time.

When comparing quotes, ask what is included. Ask what brand of components they use. Ask whether the price includes a Certificate of Electrical Safety. Ask whether surge protection is included. And check their Google reviews to see what other people’s experience has been.

Frequently Asked Questions

How long does a switchboard replacement take?

A standard single phase switchboard replacement typically takes between 4 and 6 hours. More complex installations, such as three phase upgrades or those requiring meter relocations, can take a full day or occasionally extend into a second day. We will give you a realistic timeframe when we quote the job so you can plan accordingly. Your power will need to be off for most of the installation, so we recommend planning around that.

Do I need a permit to replace my switchboard?

You do not need a building permit for a switchboard replacement in most cases. However, the work must be carried out by a licensed electrician who holds a current Registered Electrical Contractor (REC) licence in Victoria. A Certificate of Electrical Safety must be issued and lodged with Energy Safe Victoria upon completion of the work. This is a legal requirement, and any electrician who does not provide one is not complying with Victorian regulations. At Carlin Co, we issue a certificate for every prescribed electrical job we complete.

Will my power be off during the switchboard replacement?

Yes, your power will be off for most of the installation. The duration depends on the complexity of the job, but for a standard replacement you can expect to be without power for 4 to 6 hours. We will let you know the expected timeframe in advance so you can plan around it. We recommend charging devices, being mindful of fridge and freezer contents, and having a torch handy. We work efficiently to minimise the outage time.

What is the difference between an RCD and an RCBO?

An RCD (Residual Current Device) is a safety switch that protects against electric shock by detecting current leakage. A single RCD typically protects a group of circuits. An RCBO (Residual Current Breaker with Overcurrent protection) combines the function of an RCD and a circuit breaker in a single device, protecting an individual circuit against both shock and overload. The advantage of RCBOs is that if one circuit trips, only that circuit is affected, not the whole group. We recommend RCBOs for most installations because of this benefit.

Is it worth adding surge protection when replacing my switchboard?

Yes. Surge protection devices installed in your switchboard protect your home’s appliances and electronics from voltage spikes caused by lightning strikes, grid switching, and other power disturbances. Melbourne does experience severe storms, and a single surge event can damage or destroy computers, televisions, fridges, and other expensive equipment. A switchboard mounted surge protector typically costs a few hundred dollars to add during a switchboard replacement, which is a small price compared to the cost of replacing damaged appliances. We include surge protection as standard in our switchboard upgrade packages.

Can I upgrade my switchboard myself to save money?

No. In Victoria, all electrical work including switchboard replacements must be carried out by a licensed electrician. It is illegal for an unlicensed person to perform electrical work, and it is extremely dangerous. Working inside a switchboard involves handling live electrical components that can deliver a lethal electric shock. Unlicensed electrical work also voids your home insurance and can create serious safety hazards for your family and future occupants. Always use a licensed electrician with a current REC licence for any electrical work.
