Your switchboard is the heart of your home’s electrical system — every circuit, every appliance, every safety switch passes through it. If yours still has ceramic fuses or rewireable fuses, no RCD safety switches, frequent trips, buzzing or sizzling sounds, or visible scorch marks, it’s no longer safe and almost certainly no longer compliant with Australian Standard AS/NZS 3000. Aurora Electrical Solutions provides licensed switchboard upgrades and replacements across Brisbane, the Gold Coast, Logan and the wider SEQ region — fully compliant new boards with RCD safety switches and surge protection, installed by Master Electricians Australia members and certified on completion.

Signs you need a switchboard upgrade
Most Brisbane homeowners only think about their switchboard when something goes wrong. By then it’s often well overdue. Here are the warning signs we see most often on call-outs — if any of these sound familiar, book an inspection.
- Ceramic fuses or rewireable fuses (your home was likely wired pre-1991)
- No safety switches (RCDs) — required by Queensland law on power and lighting circuits
- Breakers or fuses trip frequently, especially when running the kettle, air conditioner or microwave
- Buzzing, sizzling or humming noises coming from the switchboard
- Scorch marks, melted plastic, or a burning smell at or near the board
- The switchboard is warm to the touch
- Flickering lights across multiple rooms — a sign of a loose neutral connection
- You’ve added (or want to add) major loads like a ducted air conditioner, EV charger, induction cooktop or solar system
- Asbestos-backed board (common in pre-1990 Brisbane homes — must be safely removed)
- Insurance or property sale conditions require compliance certification
How much does a switchboard upgrade cost in Brisbane?
Switchboard upgrade pricing in Brisbane varies based on the scope of work. As a guide:
- Basic single-phase switchboard upgrade with RCDs and circuit breakers: typically $1,200 – $2,200
- Full replacement including surge protection and labelling: typically $1,800 – $3,000
- Single-phase to three-phase upgrade (including Energex application): typically $2,500 – $4,500+
- Relocation of the switchboard to a new position: add $500 – $1,500 depending on cabling
- Asbestos backing-board removal and disposal: add $300 – $800
Every job is different — we provide a free fixed-price quote before any work starts, so there are no surprises. Larger or more complex jobs may need a brief on-site assessment for accuracy.
How long does a switchboard upgrade take?
Most residential switchboard upgrades take between 4 and 8 hours and are completed in a single day, with power off only for the time we’re actively working on the board (usually 2–4 hours). Larger jobs — full board replacements with relocation, three-phase upgrades, or asbestos removal — can take a full day or sometimes two. We’ll give you an accurate timeframe when we quote, and we coordinate with Energex where supply isolation is required so you’re never left without power overnight.
When should you upgrade your switchboard?
The most common reasons Brisbane customers book a switchboard upgrade with us:
- Installing a home EV charger — most older boards don’t have the capacity or RCD protection required
- Adding ducted or split-system air conditioning, especially three or more units
- Installing rooftop solar with a hybrid inverter or battery system
- Major renovation or extension — the certifier will usually require an upgrade to current code
- Replacing an electric oven, induction cooktop, or instantaneous hot water system
- Buying or selling the property — pre-purchase electrical inspections frequently flag switchboard issues
- After a near-miss — a tripped main, a scorch mark, a burnt-out fuse — don’t wait for a second warning
- Tenanted properties — landlords are legally responsible for ensuring safety switches are present and working
How the switchboard upgrade process works
We keep the process straightforward and clearly communicated from start to finish.
- Free quote and assessment — We look at your existing board, the size and age of the home, the circuits you’re running, and what you plan to add in future. You get a clear, written, fixed-price quote — usually within 24 hours.
- Scheduling and Energex coordination — We book a time that suits you. If we need to isolate supply at the meter, we lodge the Energex paperwork and confirm timing so you’re never left without power overnight.
- Install day — safe make-safe and removal — We isolate power, remove the old board (including ceramic fuses, rewireable fuses, or asbestos backing where present, safely and to AS/NZS standards), and prepare the cabinet for the new board.
- New switchboard installation — Modern enclosure, MCB circuit breakers, RCD safety switches on every required circuit, surge protection device, and a main switch sized to your load. Every circuit is labelled and documented.
- Testing and certification — Every circuit is tested in line with AS/NZS 3000. You receive a Certificate of Test and Compliance — the document your insurer, certifier or solicitor may need for property transactions.
- Handover and warranty — We walk you through the new board, show you which RCD covers what, and answer any questions. Workmanship is guaranteed and we’re a phone call away if anything ever needs attention.
Single-phase vs three-phase switchboard upgrades
Most older Brisbane homes are single-phase — one active conductor delivering power to the property. Single-phase supply is fine for most households, but the moment you start adding high-draw loads like a three-phase EV charger, ducted air conditioning, an instantaneous hot water unit, a large solar inverter, or a workshop, you can quickly run up against capacity limits. The symptoms are usually frequent main-breaker trips, dimming when an appliance kicks in, or Energex flagging your account.
Upgrading from single-phase to three-phase means a heavier supply from Energex and a larger main switch and switchboard configuration. It also opens the door to genuine three-phase appliances (faster EV chargers, larger solar systems, three-phase motors in workshops) that are simply not possible on single-phase. We handle the entire process, including the Energex application and supply coordination — you don’t need to deal with the utility directly.
Not every home needs three-phase. We’ll tell you honestly if a single-phase upgrade is sufficient for your needs and budget. There’s no point paying for capacity you’ll never use.
Safety switches (RCDs) — Queensland law
In Queensland, safety switches (also called Residual Current Devices, or RCDs) are required by law on all power and lighting circuits in any home built or rewired since 1992, and on power circuits in all homes since 2000. The Electrical Safety Act 2002 makes it the homeowner’s responsibility — and a landlord’s legal obligation on rental properties.
An RCD detects current flowing where it shouldn’t (for example, through a person touching a live wire) and cuts power within 30 milliseconds — fast enough to prevent fatal electric shock. A circuit breaker alone does not provide this protection. Every modern switchboard we install includes RCDs on every circuit, tested and certified.
AS/NZS 3000 compliance and certification
Every switchboard upgrade Aurora completes is installed and tested to Australian Standard AS/NZS 3000 — the wiring rules that govern all electrical installations in Australia and New Zealand. On completion, we issue a Certificate of Test and Compliance signed by a licensed electrical contractor (QLD Licence EC91972).
This certificate is the document your insurer may ask for if you ever make a claim, what conveyancing solicitors look for at property sale, and what building certifiers need for renovation sign-off. We keep a copy on file for you — if you ever lose your copy, just call and we’ll send you another.
