Quick Answer
A standard residential switchboard upgrade in Melbourne typically costs $1,500–$2,500 for an average-sized family home. Smaller partial upgrades may start around $800, while larger or more complex three-phase installations can cost $5,500+.
- Partial upgrade: $800–$1,500
- Standard home upgrade: $1,500–$2,500
- Larger or complex upgrade: $2,500–$3,500
- Three-phase upgrade: $3,000–$5,500+
Your price can change based on your switchboard’s age, number of circuits, access, safety devices, and any extra compliance work needed. A licensed electrician will need to inspect your property before giving a final quote.
Switchboard Upgrade Cost by Project Scope
The size and complexity of your switchboard upgrade will have the biggest impact on the final quote. A small unit with only a few circuits will usually cost less than a large family home with many appliances, extra circuits, or three-phase power needs.
1. Partial Upgrade or Safety Switch Addition: $800–$1,500
A partial upgrade may suit you if you live in a small apartment or unit, or your home only needs minor safety improvements. This may include:
- Replacing outdated ceramic fuses
- Adding RCD protection
- Updating selected old components
- Improving safety without replacing the whole board
Keep in mind that this is generally not the same as a complete switchboard replacement.
2. Standard Full Switchboard Replacement: $1,500–$2,500
This is the most common option for a typical 3- to 4-bedroom family home. It may suit older homes with several outdated fuses or breakers.
A standard upgrade may include:
- A new switchboard enclosure or panel
- Modern circuit protection
- RCBOs and RCD protection
- Surge protection where needed
- Clear labelling and testing
3. Large Home or Complex Upgrade: $2,500–$3,500
Larger homes often need more parts and labour. Your quote may be higher if your home has:
- More than 20 electrical circuits
- A larger switchboard
- More RCBOs
- Extra wiring
- Consumer mains requirements
- More compliance work
4. Three-Phase Power Upgrade: $3,000–$5,500+
Three-phase power may be considered if your home has high electrical demand, such as large ducted air conditioning, high-powered EV charging, pools, or many large appliances.
A switchboard upgrade and a three-phase supply upgrade are not always the same job. A licensed electrician must assess your home and confirm the right scope.
What Affects the Cost of a Switchboard Upgrade in Melbourne?
The cost of your switchboard upgrade depends on your home’s needs. Some jobs are simple. Others need more parts, more time, and extra safety checks. Here are the main things that can affect your quote.
1. Number of Electrical Circuits
Each circuit may need its own protection device. So, if your home has more circuits, the job can cost more. Your electrician will check:
- How many circuits you already have
- How many RCBOs are needed
- How much space is available in the board
- Whether any circuits need to be changed or replaced
2. Asbestos Switchboard Components
Older Melbourne homes may have asbestos backing boards or parts inside the switchboard. This may add to cost because asbestos must be handled safely. Specialist removal and proper disposal may be needed. You should never try to remove suspected asbestos yourself.
3. Consumer Mains Upgrades
Your incoming power supply may not suit your home’s current needs. Older or undersized consumer mains can mean extra cabling, labour, and materials. For example, some homes may need larger mains cables, but this depends on the property. Your electrician must assess this on-site.
4. Single-Phase vs Three-Phase Power
Single-phase power suits many homes. Three-phase power is often used for higher loads, such as large air conditioning, workshops, or EV chargers. It usually costs more because the work is more complex.
5. Surge Protection and Modern Safety Devices
Your upgrade may include:
- RCBOs
- RCD protection
- Surge protection
- Modern circuit breakers
- Better labelling
Surge protection can help protect appliances from voltage spikes.
6. Inspection and Compliance Requirements
In Victoria, electrical work may require inspection, testing, certification, and a Certificate of Electrical Safety (COES).
What Is Included in a Typical Switchboard Upgrade?
A switchboard upgrade is not just swapping one part for another. You are paying for parts, labour, safety checks, and proper setup. A typical upgrade may include:
- Inspection of your existing switchboard
- Removal of old or unsafe components
- Installation of a new switchboard enclosure where needed
- New circuit breakers or RCBOs
- RCD protection for improved safety
- Surge protection, if included in your quote
- Circuit identification and clear labelling
- Electrical testing after the work is done
- Compliance documents
- Electrical safety certification where required
These steps help ensure your switchboard is safer, easier to use, and suited to your home’s power needs.
It is important to know that not every quote includes the same scope. One electrician may include surge protection, certification, or asbestos handling, while another may not.
That is why comparing the total price alone can be misleading. Always check what is included before choosing a quote.
Does an Old Switchboard Need to Be Replaced?
Yes, an old switchboard may need replacing if it no longer keeps your home safe or cannot handle your power needs. This is especially common in older Melbourne homes.
Watch for warning signs like:
- Ceramic fuses
- Missing safety switches
- Cracked or damaged parts
- Burning smells or scorch marks
- Buzzing or strange noises
- Frequent tripping
- Overloaded circuits
- An old or damaged enclosure
- Power needs that have outgrown the system
If you notice any of these issues, it is best to have a licensed electrician inspect it.

Is a Switchboard Upgrade Worth It?
Yes, a switchboard upgrade can be worth it, especially if your current board is old, crowded, or missing modern safety devices. It is not just about cost. It can make your home safer and better prepared for today’s power needs.
Key benefits include:
- Improved electrical safety
- Modern circuit protection
- Better protection from electrical faults
- More capacity for modern appliances
- Support for future upgrades
- Help with EV charger installation where suitable
- Better compliance for older electrical systems
If you are unsure whether to repair or replace your switchboard, a licensed electrician can inspect it and explain your options.
How to Save Money on a Switchboard Upgrade
You can save money on a switchboard upgrade by knowing exactly what you are paying for. The cheapest quote is not always the best choice, especially with electrical work.
Before you agree to a quote, you should:
- Ask for a detailed written quote.
- Confirm which safety devices are included.
- Check if asbestos removal is included, if needed.
- Ask if consumer mains upgrades are included.
- Confirm inspection and certification costs.
- Ask whether surge protection is included.
- Compare quotes by scope, not just price.
- Use a licensed electrician.
A qualified electrician can help you avoid unsafe shortcuts and costly problems later.
What Should a Switchboard Upgrade Quote Include?
When comparing quotes, do not look at price alone. Check what each electrician has included so you can compare fairly.
Your switchboard upgrade quote should clearly list:
- New switchboard/panel: shows if the board itself is being replaced
- Number of RCBOs: helps show the level of circuit protection
- RCD protection: important for electrical safety
- Surge protection: confirms if surge protection is included
- Consumer mains work: can greatly change the total cost
- Asbestos removal: important for older homes
- Labour: helps you compare quotes
- Testing and inspection: confirms the work has been checked
- COES/certification: shows who handles safety documents
- GST: makes the final price clearer
