Who a full switchboard replacement suits
A full replacement swaps an old board, with ceramic fuses or a crowded jumble of add-ons, for a new enclosure fitted with circuit breakers and safety switches. It suits older Sydney homes where the board keeps tripping, has no spare room or has been flagged as outdated.
Signs of an outdated switchboard
Common signs include fuses that blow or breakers that trip often, a scorched smell or warm cover, flickering lights when appliances start, and no space left to add a circuit for solar or an EV charger. Any of these is worth having checked.
What a compliant new board looks like
A completed replacement has a new enclosure, each circuit protected by a labelled breaker, safety switch protection and spare room to grow. The work must be done by someone holding a NSW electrical licence, whatever the job costs, then tested and certified with a CCEW.
How the power-off time works
Power is switched off while the old board comes out and the new one goes in. For a straightforward swap that is usually several hours to around a day. Where the supply or meter connection must be changed, the network distributor may need to be involved.
Why switchboard replacement quotes vary
Quotes differ because the scope differs: board size, number of circuits, safety switches, cabling condition, meter position and access all change the job. Some quote the board alone, others itemise testing, labelling and the CCEW. Comparing line by line shows whether two prices cover the same work.
Price changes and the decision to proceed
Old wiring, damaged cabling or hidden faults sometimes only show up once the cover comes off, which is why some quotes change. Ask how any extra work would be priced and approved before it starts. Once residential work passes $5,000 including GST, a written contract is required.
Next step for your old switchboard
Note your suburb, property type and what you have noticed, such as tripping or a full board. A photo of the board helps but is optional. Decide whether you want spare space for solar or an EV charger, so every quote is priced on the same board.

How it works
- 1
Assessment on site
A licensed electrician inspects the existing board, wiring and meter position, then sets out the scope and price in writing.

Power disconnected
On the day, supply is isolated so the old board can be removed safely. Plan for the power being off for several hours, sometimes up to a day.
- 3
New board fitted
The new enclosure, breakers and safety switches are installed, and each circuit is reconnected and labelled.
- 4
Testing and CCEW
The work is tested, power is restored, and a CCEW is submitted through the NSW eCert portal with a copy provided to you.
