Pricing guide

The cost of a dedicated circuit depends mainly on the circuit type, materials and whether the existing switchboard or supply can accommodate it. Standard residential single-phase work with routine access is typically less complex than three-phase or EV/high-draw installations, which usually need heavier cable and different protective devices. Callout fees, after-hours attendance and any required switchboard or supply authority work also affect the final price.

  • Circuit type and amperage

    Higher-capacity circuits, three-phase work or EV-ready setups usually require heavier cable and specialised breakers that increase material and handling effort.

  • Number of circuits required

    Installing multiple dedicated circuits increases materials, labour time and the likelihood of needing additional switchboard capacity.

  • Switchboard and supply capacity

    If the existing board or incoming supply lacks capacity, a replacement or supply authority/metering upgrade is commonly required and expands the job scope.

  • Installation route and access

    Routing through walls, ceilings, long conduit runs or under slab can add labour and may require chasing or slab coring.

  • Timing and callout arrangements

    A callout fee and standard labour rates usually apply, while after-hours or urgent attendance is commonly charged at a higher rate.

Frequently asked questions

Do electricians need to be licensed for this work?
Yes — electrical installations require a licensed electrician in Australia. A licensed electrician can issue the appropriate compliance paperwork and should hold the necessary licences for wiring and switchboard work.
Will I need a switchboard upgrade?
Not always; if the existing board lacks spare capacity or compatible breakers, an upgrade may be needed. Where required, electricians usually quote the upgrade separately and may coordinate any supply authority or metering checks.
How disruptive is the installation to my home?
Standard installations with clear access routes are usually low-disruption and can often be completed without major building work. If chasing walls, slab coring or a full board replacement is needed, the work is typically more disruptive and may involve additional trades.
What checks are done before installing a circuit?
An electrician will typically confirm whether the property has single- or three-phase supply, available breaker space, and a suitable cable route. If three-phase isn’t available or the incoming supply is insufficient, further supply authority or metering work may be necessary.
How accurate is the instant estimate?
Our estimates are built from research across thousands of local jobs and real pricing data. Use them as a guide when speaking to electricians — your actual quote will depend on your specific job.
