Electrical switchboard upgrade is a crucial step in increasing the safety and efficiency of your home electrical system. It ensures your electrical system can handle modern demands while preventing potential hazards like electrical fires or shocks. Although costs vary, the benefits of enhanced protection, reliability, and compliance with safety standards far outweigh the initial expense.
How Much Does a Switchboard Upgrade Cost?
It is important to upgrade your switchboard so that you can maintain the electrical system of your home in good shape. Older switchboards might not meet the current safety requirements, and they might struggle to support an increased energy intake as older buildings age and more electricity is required. An improved switchboard may help you save yourself from electrical fires, shocks, and technical issues. The cost of a switchboard upgrade can vary depending on factors like the size of the property, the electrical load, the type of switchboard, and the difficulty of installation.
What is an Electrical Switchboard?
An electrical switchboard is the central control hub for your home’s electrical system. It distributes electrical power to various electrical circuits within the home and provides circuit protection from overloads, short circuits, and faults, including the use of a residual current device. The switchboard houses key components such as circuit breakers, fuses, and safety switches that ensure the system operates safely and efficiently. It serves as the point where electricity enters your home, allowing it to be safely distributed to different parts of the home’s electrical wiring.
Key Factors Influencing Switchboard Upgrade Costs
Property Size and Electrical Load
Probably the greatest aspect that will influence the price of a switchboard upgrade is the size of your premises and electrical loading. Bigger houses or multi-storeyed homes, or homes that have one advanced electrification system or fitting, might need a switchboard that can support a greater capacity, especially if the existing wiring is outdated. The more electrical load due to major electrical appliances, a home office, an air conditioner, or an electric heater, the switchboard will be required to carry the electrical current without endangering the source.
Besides the amount of space your property occupies, the number of circuits and outlets you possess would also determine the complexity of the upgrade. Bigger houses with increased appliances will require a switchboard with more new circuit breakers, and this will raise the materials and labour prices, which could also prompt an electrical defect notice if not addressed. Therefore, it would only stand to reason that the upgrade will be costly for high electrical demand homes. The greater the number of appliances or devices you have connected to your system, the more circuits you require to distribute the load safely.
The Type of Switchboard
The kind of switchboard you choose will also influence the price. Its various varieties exist, and these fit various needs, particularly those that prioritise enhanced safety.
- Basic Single-Phase Switchboard: This is a standard for protecting and laying out electricity commonly found in smaller homes. It is normally the cheapest and can be applied to houses that have relatively low requirements of electricity. Single-phase switchboards are generally fitted in houses with fewer circuits and fewer appliances, normally a smaller home unit or apartment.
- Three-Phase Switchboard: Homes with more electrical appliances or homes with larger sizes need a three-phase switchboard. They distribute a load better and are suitable in a house with air conditioning and heavy appliances or electric heating. Three-phase is more costly; however, it is also more reliable when the property has a high demand. More efficient and offers smoother operation of homes that demand heavy use of electricity.
Why Should You Upgrade Your Electrical Switchboard?
Enhanced Electrical Safety
The major motivation to upgrade an electrical switchboard is safety. Due to the overloaded or old switchboards, a level of protection might not be sufficient, and the risk of electrical faults, fires, or electric shock can increase. New switchboards have circuit breakers, rcd safety switches, and surge protection to protect your home, playing a critical role in preventing electrical fires. The systems are uniquely positioned to handle increased electrical loads and ensure the safety of your house.
The electrical requirements of modern homes that are usually filled with many large electrical appliances, including solar power systems, a home entertainment system, and office equipment, may not be supported by old switchboards. When the old switchboard is overfilled, there may be overheating, power surges, or even the ignition of sparks. The replacement of a switchboard with higher safety properties, especially considering the existing infrastructure, is a significant step in safeguarding your house and your loved ones against electrical hazards.

Reduced Fire Risk
The old switchboards also cause fire-wise electricity. Old systems usually have worn-out wiring or obsolete parts that are not able to control electrical loads appropriately. The overloading may lead to overheating, sparks, and even a physical fire. However, modern switchboards are designed to be energy efficient and do not pose a fire hazard.
Through the enhancement of your switchboard, you minimise the chances of a fire hazard. New systems with RCDs, circuit breakers, and overload protection will automatically cut the power during the switchboard upgrade process and avert electrical fires before they happen. This may be of particular concern to houses at risk or those built many years ago with an old electrical system. Electrical wire fires can easily be avoided by having the latest safety fittings, which are fitted to newer switchboards, along with regular electrical tests.
Easier Maintenance and Repairs
A new switchboard also helps qualified electricians to carry out maintenance and repair easily. They have good labelling and are accessible, thus allowing easy identification of the problems within a short period, which is beneficial for electrical contractors. This may also save costs and time taken in future maintenance or repairs. More so, a great number of new systems present remote monitoring options, and you can monitor energy use and system performance via applications or smart gadgets.
Better accessibility of recent switchboards means your electrical system will be accessible in the case of servicing, but it will not be delayed or complex. Additionally, dealing with problems like flickering lights with a better switchboard will undoubtedly help you sell your house for more money. Electrical systems that are checked with the current modern standards, including the current switchboard, are more appealing to potential buyers, hence increasing the attractiveness of your home in the market. One major selling point is peace of mind, which results in having a safe and reliable electrical system.
Breaking Down the Costs of a Switchboard Upgrade
New Switchboard (Material and Parts)
One of the biggest expenses is the cost of the switchboard itself. The simple single-phase switchboard would cost between 300 and 500, and a more rated three-phase switchboard could take anywhere between 700 to 1500 and above, depending on the brand and the features. These products are often adopted by most people since this price entails necessary features such as circuit breakers, safety switches, and other entire parts but may incur additional costs for installation.
What will add another amount to the cost of switchboards is the option to add some extra features, such as surge protection or compatibility with smart home systems. Surge protection devices help to avoid surge damage, and smart capabilities allow monitoring and controlling the consumption of energy more effectively. These characteristics are excellent when it comes to people who want more control and security over the electrical system of their home.
Rewiring and Cabling Costs
Rewiring and cabling also come with the upgrade of the switchboard, especially when you have old wiring or electrical wiring that cannot support the new system. How much it will cost to rewire will depend on the size of your property, the complexity of your electrical system, and the number of power outlets you need. Depending on the average, rewiring, depending on the condition, may cost between 200 dollars and 1000 dollars.
The necessity of rewiring is even better seen in old houses or when you are changing to a three-phase system. The houses or properties that are newer or have an existing, modern wiring system might not require much rewiring. Nevertheless, rewiring is mandatory in creating a smooth operation between the new switchboard and your power system. It is important that the current electrical infrastructure, including an effective grounding system, is capable of meeting the current electrical needs.
Electrician Labour Costs
Another important component of the switchboard upgrade budget is the cost of the electrician’s labour. While rates can vary by region, skilled local electricians typically charge between $80 and $120 per hour, depending on the complexity of the job. The time required to complete the upgrade depends on several factors, including the type of switchboard, the size of the property, and other site-specific conditions.
