Really appreciate the work undertaken by Jacob - installing an EV charger into the car port of my apartment building. From the beginning the process was made clear and completed with courtesy: starting with the initial inspection and quotation (which was quoted at the start and did not change at completion). The work was undertaken in a short time frame, mess was cleaned up and Jacob didn't leave until we had tested it with my car and ensured the settings on the charger were enabling enough electricity through to the car. Really pleased and will use again for future work.Posted on Liam Ingram12 January 2026Trustindex verifies that the original source of the review is Google. Installed an EV charger and reshuffled works to accommodate a separate emergency of ours another time. Very friendly and good communication.Posted on Christopher Dalley3 January 2026Trustindex verifies that the original source of the review is Google. Jacob and the team were very professional, polite and easy to work with. I had extensive requirements including a IXL light fitting, smart mirrors, many multi-GPO swap outs, new GPOs in several rooms, replacement external lights and pendant installations.

I had a great experience with Jacob Navosa from Jen Electrical. He quickly identified that the issue with my lights was due to faulty fittings and explained everything clearly so I could understand. He also installed my replacement oven, and the whole process was smooth and professional. Jacob’s knowledge and expertise were very reassuring, but what stood out most was his excellent communication, customer service, and friendly personality. It’s rare to find someone who combines technical skill with such great people skills. I highly recommend Jacob and will definitely be using his talents for future work.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

The cost for three phase power upgrade services typically ranges from 2,500 to 6,000 for residential properties, making it a significant but worthwhile investment for properties with high electrical demands. Commercial electrical upgrade costs can vary more widely depending on the complexity and scale of the installation.
Several factors influence the cost to upgrade to 3 phase power, including the distance from your property to the nearest three-phase supply, the condition of your existing electrical infrastructure, and whether you choose overhead or underground connections. Properties requiring extensive rewiring or switchboard modifications may see higher costs due to additional labour and materials.
The total cost depends on several key factors that our electricians assess during the initial consultation. Distance from the street connection point significantly impacts pricing, as longer cable runs require more materials and labour time.
Existing electrical infrastructure condition also affects costs. Older properties may require additional upgrades to wiring, earthing systems, or switchboard components, increasing the overall investment. However, these upgrades ensure your electrical system meets current safety standards and can reliably support three-phase power distribution.
The choice between overhead and underground connections influences pricing as well. While underground connections may have higher initial costs, they often provide better aesthetics and protection from weather-related issues.
While the initial cost to upgrade to 3 phase power represents a substantial investment, the long-term benefits often justify the expense. Properties with upgraded electrical systems typically see improved energy efficiency, reduced equipment wear, and increased capacity for modern appliances and systems.
The investment should be viewed as positioning your property for future electrical needs. As electric vehicles, solar systems, and high-efficiency appliances become more common, having robust electrical infrastructure positions your property to accommodate these technologies without additional major electrical work.
Planning to install ducted air conditioning, electric vehicle chargers, or commercial-grade kitchen equipment? These applications often require the increased capacity that only electrical system upgrades can provide. Without adequate electrical infrastructure, these appliances may not operate efficiently or could overload your existing single-phase system.
The electrical upgrade becomes essential when your electrical demands exceed what single-phase power can reliably supply. This is particularly common in larger homes, commercial properties, or facilities with multiple high-consumption devices operating simultaneously.
If you're experiencing frequent circuit breaker trips or power outages when running multiple appliances, these are clear indicators that your current electrical system needs upgrading. Single-phase systems often struggle with the electrical demands of modern properties, leading to reliability issues and potential equipment damage.
Upgrading to three phase power eliminates these problems by distributing electrical loads across three phases, reducing strain on any single circuit and providing more stable power delivery throughout your property.
Commercial properties almost universally benefit from electrical system upgrades due to their higher electrical demands and need for reliable power distribution. Manufacturing equipment, commercial HVAC systems, and large-scale lighting installations all operate more efficiently with three-phase power supply.
The upgrade also provides better load balancing for commercial properties, reducing energy costs and improving equipment lifespan. This makes the investment worthwhile for business owners looking to improve operational efficiency.
Our electricians are waiting for your call. Get service within 60 seconds to fix any issues you may be having.
Every project begins with a comprehensive assessment of your property's electrical needs and existing infrastructure. Our qualified electricians evaluate your current system, discuss your power requirements, and provide detailed cost information tailored to your specific situation.
During this assessment, we also verify the availability of three-phase power in your area and coordinate with your electricity provider to understand any specific requirements for your electrical upgrade project. This thorough planning ensures accurate cost estimates and smooth project execution.
The upgrading to three phase power process involves installing new service mains and consumer mains cables, which may run overhead from network poles or underground through network pillars, depending on your area's electrical distribution system.
We handle all aspects of the infrastructure work, including setting up connection pillars, private poles, or points of attachment as required by your local electricity network configuration. This comprehensive approach ensures your electrical upgrade meets all technical and regulatory requirements.
A critical component of any electrical system upgrade is installing a new three-phase switchboard capable of properly distributing power across all three phases. Your existing switchboard will typically require replacement or significant modification to accommodate the three-phase system safely and efficiently.
The new switchboard installation includes circuit breakers with three switches linked together, ensuring balanced power distribution and proper protection for all electrical circuits. This switchboard upgrade is essential for the safe and reliable operation of your upgraded electrical system.
Once the physical installation is complete, our electricians conduct comprehensive testing to verify that all systems operate correctly and safely. This testing phase ensures your electrical upgrade meets Australian electrical standards and provides reliable power distribution.
We also provide detailed documentation of the work completed, including test results, compliance certificates, and operating instructions for your new electrical system.
