What Affects the Cost
Existing wiring age. Victorian-era homes (pre-1940) often have rubber-insulated or cotton-sheathed wiring that fails insulation resistance testing. Expect $200–$500 per circuit for partial rewiring.
Asbestos presence. Common in boards installed before 1990. Licensed removal adds $150–$800. In Victoria, non-friable asbestos under 10m² can be removed following safe work procedures; larger quantities or friable asbestos require a licensed asbestos removalist under WorkSafe Victoria's compliance code.
Sub-mains cable. Older properties may have undersized or aluminium mains ($600–$1,200 for replacement). Aluminium, common in 1960s–70s builds, loosens at connections over time due to thermal expansion — a fire risk.
Heritage overlay. Heritage-listed homes in inner Melbourne may restrict where the board is mounted and whether external conduit is visible. New wiring must be fully concealed; original switches and outlets must be retained in-situ. A planning permit ($1,300–$1,500, 6–8 weeks processing) may be required.
Board size. If you are planning solar, battery, or an EV charger, sizing the board up now (36-pole instead of 24-pole, ~$30–$40 more for the enclosure) avoids paying for a second upgrade later.
Prescribed work inspection. Victoria requires a Licensed Electrical Inspector to inspect the switchboard before power is reconnected. This is included in the electrician's service but affects scheduling — the board stays de-energised until inspected (within 8 business days).
Rental properties. Since 29 March 2023, all Victorian rental properties must have circuit breakers and RCDs — not ceramic fuses. Landlords who fail to comply risk tenants terminating the lease or claiming up to $2,500 for urgent repairs.
Smoke alarms. Homes built or renovated after 1 May 2014 require hardwired interconnected photoelectric smoke alarms (ionisation type prohibited in VIC). Adding these during a switchboard upgrade costs $140–$350 per alarm.
A straightforward upgrade in a 1990s brick veneer home with good access, modern wiring, and 10–12 circuits sits toward $1,000. A Victorian terrace in Fitzroy or Carlton with rubber-insulated wiring, asbestos backing, undersized sub-mains, heritage overlay restrictions, and a prescribed work inspection pushes toward $3,600.
Melbourne-Specific Considerations
Inner suburbs and heritage zones. Fitzroy, Carlton, Brunswick, Richmond, South Melbourne. Packed with Victorian and Edwardian terraces, many still with original rewirable fuse boxes and wiring dating back 80+ years. These properties almost always need sub-mains replacement alongside the switchboard, as the existing cable cannot handle modern loads. Heritage overlay zones restrict visible conduit runs on facades — check your property's heritage status on the City of Melbourne Interactive Maps (CoMMaps) before booking the job.
Eastern suburbs. Doncaster, Glen Waverley, Templestowe. Larger homes from the 1970s–90s with higher circuit counts. These typically need a board upgrade but the wiring is usually serviceable. 36-pole boards are common for homes running ducted heating, split system AC, solar, and multiple appliance circuits. Covered by AusNet Services.
Bayside suburbs. Brighton, Sandringham, Hampton. Mix of older and newer homes. Salt air can accelerate corrosion on switchboard terminals in older outdoor enclosures. Covered by United Energy.
Western and northern growth corridors. Tarneit, Werribee, Craigieburn, Mickleham. Post-2000 homes with compliant boards rarely need full upgrades. These properties may need additional circuits for solar or EV chargers — adding an RCBO-protected circuit costs $143–$300. Covered by Powercor.
Five electricity distributors cover Melbourne: CitiPower (CBD and inner suburbs), Jemena (northern and south-western suburbs), Powercor (outer western), AusNet Services (eastern), and United Energy (south-eastern). Use the postcode locator on your power bill to determine your distributor. Meter panel work is the distributor's responsibility — your electrician handles the switchboard and house wiring only.
Hiring a Licensed Electrician in VIC
Victorian electricians must hold a current licence registered with Energy Safe Victoria (ESV). You can verify a licence on the ESV public register. After completing a switchboard upgrade (prescribed work), they must arrange a Licensed Electrical Inspector to inspect the work, then lodge the CES within 16 calendar days.
Ask for confirmation that the prescribed work inspection has been completed and the CES has been lodged. If the electrician says a CES "isn't needed" for a switchboard replacement, find another electrician — it is legally required.
