Subiaco is one of Perth’s most established inner suburbs, sitting a few kilometres west of the CBD with a housing stock that tells the story of a century of residential Perth. Federation-era cottages, mid-century brick and tile homes, and more recent apartment developments sit side by side in streets that have changed considerably over the decades. For homeowners in Subiaco, the electrical demands of modern living frequently come into conflict with the infrastructure that older properties were built with – and that gap is where most of the suburb’s electrical work originates.
The Reality of Older Wiring
Homes built before the 1980s in suburbs like Subiaco were wired for a very different domestic environment. Two-bedroom cottages with one bathroom and a modest kitchen simply did not need the electrical capacity that the same home requires today – reverse cycle air conditioning, multiple large appliances, home office setups, electric vehicle chargers, and entertainment systems that draw power continuously.
The wiring in many of these homes reflects when it was installed. Older cable types, fuse boards rather than modern circuit breaker panels, and limited circuit capacity are common findings when an electrician works in a Subiaco property for the first time. This does not necessarily mean the wiring is unsafe – but it does mean that adding new circuits or increasing load on existing ones needs to be approached carefully, and a switchboard assessment is often a sensible starting point before any significant electrical work begins.
Switchboard Upgrades in the Inner Suburbs
Switchboard replacement is one of the most common larger electrical jobs in Subiaco and surrounding inner suburbs including Shenton Park, Daglish, and West Perth. Replacing an old ceramic fuse board with a modern safety switch and circuit breaker panel brings a property up to current standards, improves safety, and provides the capacity for additional circuits to be added as needed.
The cost of a switchboard upgrade varies depending on the size of the existing board, the incoming supply capacity, and whether the meter box needs to be replaced at the same time. It is not a small job, but for a home that is being renovated or where the existing electrical infrastructure is clearly at capacity, it is often the right foundation to start from rather than trying to work around limitations that will keep resurfacing.
Renovations and Heritage Considerations
Subiaco has a significant amount of heritage-listed and character housing, and renovation work in these properties comes with constraints that affect how electrical upgrades can be carried out. Running new circuits through walls or ceilings in a heritage property often cannot be done the same way it would in a standard suburban home, and an electrician who has worked in Subiaco’s older housing stock will be familiar with the practical approaches that work in these environments.
If you’re planning a renovation in a character home and electrical upgrades are part of the scope, it’s worth discussing the heritage constraints with your electrician early in the planning process. The routing options for new cabling, the placement of additional power points, and the approach to concealing conduit all benefit from being thought through before any walls are opened up.
Solar and EV Chargers in an Inner Suburb Context
Solar installations and EV charger installs are increasingly common across Subiaco as residents upgrade their homes and look to reduce running costs. Inner suburb properties present some specific considerations – smaller roof areas, more complex roof pitches, and in some cases heritage restrictions on panel placement all affect the design of a system.
For EV charger installation, the key question is usually switchboard capacity and the distance of the run from the board to the garage or parking area. In older Subiaco properties where the switchboard is being upgraded at the same time, it is worth combining these jobs to reduce the overall cost of both.
