Start with what your switchboard looks like now
Open the switchboard door and take a look before you pick a service. What you see narrows the choice quickly.
Ceramic fuses or rewireable fuse holders
If your board has pull-out fuses with wire inside, fuse box replacement is the usual starting point. It swaps the old fuses for modern circuit breakers and gives you a board that suits current household loads.
Breakers but no test buttons
A board with circuit breakers but no safety switches (the devices with a small "T" test button) may only need safety switch installation, provided there is room on the board and the wiring behind it is in reasonable shape.
Scorch marks, a crowded board or an asbestos backing panel
When the whole enclosure is old, cramped or showing heat damage, switchboard replacement is generally the cleaner option. A full new board can leave space for extra circuits later, which may reduce the need for another upgrade down the track.
Think about what you plan to add
Your future power use matters as much as the board's age.
- Solar panels or a home battery: a solar ready switchboard upgrade sets aside space and suitable protection for the inverter connection.
- Ducted air conditioning, an EV charger or a big renovation: a three phase switchboard upgrade can spread heavy loads across more supply capacity. Three phase changes the connection to the street, so it involves the local network distributor as well as the board itself.
- A meter enclosure that is rusted, too small or in an awkward spot: a meter box upgrade deals with the box that houses the meter, which often goes hand in hand with solar or three phase work.
- Expensive electronics, appliances or a home office: surge protection installation adds a device at the board to help guard connected equipment against voltage spikes. It is commonly added during a larger upgrade rather than booked on its own.
Combining services in one job
Plenty of Sydney homes need more than one item from this list. A typical combination is a full board replacement with safety switches and surge protection, or a meter box upgrade alongside a solar ready board. Asking for these together in one quote makes it easier to compare like with like.
Rules that apply to every switchboard job in NSW
Whichever service you choose, the wiring must be done by someone who holds a NSW electrical licence or certificate, no matter how small the job. After testing, the work is certified with a Certificate of Compliance for Electrical Work (CCEW) lodged through the Building Commission NSW eCert portal, and you should receive a copy.
A standard upgrade inside an existing home does not normally need a council development application. Work that changes the network connection, such as moving to three phase, may need approval from the distributor.
For larger jobs, check the paperwork before you pay anything:
- Residential work over $5,000 including GST needs a written home building contract.
- Statutory warranties cover the work for six years for major defects and two years for other defects.
Deciding on your next step
Take a photo of the board with the door open, note whether it has fuses, breakers or safety switches, and list anything big you plan to install in the next few years. With that in hand you can tell which service fits, then request a quote here and a licensed and insured local contractor can follow up.
