How Much Does It Cost to Wire a New House in Perth?

Electrical rough-in and fit-off is one of the larger trades packages in a new home build and it is worth understanding what you are paying for before you accept a quote. Prices vary significantly depending on the size of the home, the specification level, and what the builder has included in their contract versus what falls to the homeowner or the electrical contractor directly.

What new home electrical work involves

A complete electrical package for a new residential build in Perth covers two main stages. The rough-in is done after the frame is up and involves running all the cables through the walls, ceiling, and floor cavities before the plaster goes on. The fit-off is done after plastering and covers installation of all the fittings including power points, light switches, lights, the switchboard, safety switches, and circuit breakers.

Some builders include a basic electrical allowance in their fixed price contract. Others quote it as a separate trade. Read your contract carefully to understand what is and is not included.

What does new home wiring cost in Perth?

Electrical costs for a standard new home in Perth typically fall between $8,000 and $18,000 depending on the size of the home and the specification. The main variables are:

• Total floor area and number of rooms
• Number of power points, light fittings, and circuits
• Whether split system air conditioning wiring is included
• Whether solar and battery storage pre-wiring is included
• Smart home or home automation requirements
• Level of finish on light fittings and power points

A basic three bedroom two bathroom home on a standard specification typically comes in between $8,000 and $12,000 for a complete rough-in and fit-off. Larger homes or those with higher specifications sit above that range.

What to look for in a new home electrical quote

Make sure the quote specifies the number of power points and lights included, whether the switchboard is sized appropriately for future additions like solar or EV charging, what allowance is made for any fittings the homeowner is supplying, and whether the price includes the Certificate of Compliance on completion.

Watch for quotes that are priced low on power point counts. Adding extra power points once walls are plastered costs significantly more than including them in the original rough-in.
