01 / Overview
Switchboard Upgrade done properly, the first time.
Stewart Electrical Group provides licensed switchboard upgrades across Sydney for homeowners, businesses and strata properties. We replace older boards with modern circuit breakers and safety switches, bringing the property up to current Australian standards and significantly improving electrical safety.
Most pre-2000s Sydney homes still run ceramic fuses or partial protection. A modern switchboard adds residual current devices on every circuit, clear labelling, surge protection where required, and capacity for future loads such as EV charging, ducted air conditioning or a solar inverter.
We handle single-phase and three-phase customer-side upgrades and coordinate accredited Level 2 partners where network-side service changes are required. Every included upgrade is tested, signed off and issued a Certificate of Compliance for Electrical Work (CCEW) where required.

04 / Frequently Asked Questions
Switchboard Upgrade Sydney questions, answered.
How much does a switchboard upgrade cost in Sydney?
+
Most standard residential switchboard upgrades in Sydney sit in a defined range depending on the size of the existing board, number of circuits, condition of the meter enclosure and whether any level 2 work is required. We give a clear written quote after a short on-site assessment.
How long does a switchboard upgrade take?
+
A typical single-phase residential upgrade is completed in one day. Three-phase upgrades and commercial boards may take longer if network coordination is required. We confirm timing before booking.
Do I need to upgrade my switchboard?
+
If your board still has ceramic fuses, no safety switches on every circuit, signs of overheating, or you're adding significant new loads (EV charger, ducted AC, pool plant, solar), an upgrade is generally required for safety and compliance.
Will my power be off during the upgrade?
+
Power is off only while the board is being changed over, typically a few hours mid-day. We plan the cut-over to minimise disruption and restore power by the end of the day for standard residential jobs.
Do you handle level 2 work and network coordination?
+
Yes. Where the upgrade involves work on the service side (meter, mains, point of attachment), we coordinate an accredited Level 2 partner for the required network-side work and notifications.
Do you provide a Certificate of Compliance?
+
Yes. Every switchboard upgrade is tested in full and issued a Certificate of Compliance for Electrical Work (CCEW), which you'll need for insurance, conveyancing and strata records.
