In the latest entry of our “Ask an Electrician” series, we’re addressing a critical aspect of home electrical safety and efficiency that concerns many homeowners in Sydney. Mr Sparky services homes across Sydney and specifically in their local area of Marrickville and Inner West Sydney: the cost of upgrading a switchboard. As homes are filled with more appliances and devices, the demand for old electrical systems increases, making switchboard upgrades a matter of convenience and safety.

Why Upgrade Your Switchboard?

Switchboard upgrades are essential for several reasons:

  • Safety: Modern switchboards include safety switches that protect against electrical fires and shocks.
  • Capacity: Older switchboards may not handle the electrical load of modern appliances, leading to frequent tripping or, worse, overheating.
  • Compliance: Upgrading ensures your electrical system complies with Australian Standards (AS/NZS 3000).

Factors Influencing the Cost

The cost of upgrading a switchboard can vary widely, influenced by:

  1. The Size of Your Home: Larger homes may require switchboards with more capacity, increasing the cost.
  2. The Age of the Existing Installation: Older systems might need more work to meet current standards.
  3. Additional Safety Features: Installing safety switches and circuit breakers for additional protection can affect the overall price.
  4. Accessibility and Condition: The ease of access to your existing switchboard and the condition of your home’s wiring can impact labour costs.

Average Costs in Sydney

While prices can vary based on the specifics mentioned above, here’s an estimate of what homeowners might expect to pay for a switchboard upgrade:

  • Basic Upgrade: For a small to medium-sized home requiring a standard upgrade with a few new circuits, prices can range from $800 to $1,500.
  • Comprehensive Upgrade: For a larger home or a system requiring significant work to meet safety standards, costs could escalate to between $1,500 and $3,000 or more.

Hypothetical Scenario: The Nguyen Family in Inner West Sydney

The Nguyen family, residing in a quaint, 1950s-era home in Inner West Sydney, realized their frequent power outages and flickering lights were signs of an outdated switchboard. Concerned for their family’s safety and wanting to future-proof their home, they decided it was time to upgrade.

  • Initial Assessment: A licensed electrician inspected their old switchboard, noting the lack of safety switches and the insufficient capacity for modern appliances.
  • Quoted Cost: They were quoted $2,000 for a comprehensive upgrade, which included replacing the old switchboard with a modern one featuring safety switches and circuit breakers and rewiring some sections of the home to comply with current standards.
  • Outcome: Post-upgrade, the Nguyen family enjoyed a safer, more reliable electrical system, free from tripping circuits and flickering lights.
