What’s Involved

What a Switchboard Upgrade Involves

  • A new switchboard to replace the old one
  • Modern circuit breakers with RCD protection, or individual RCBOs so one fault doesn’t take out the whole house
  • Clear labelling on every circuit
  • Spare poles left for future circuits, like an EV charger or air con
  • Full testing before we hand it back
  • An Electrical Safety Certificate when it’s done

Signs to Look For

Is Your Board Due?

  • It still has old ceramic fuses
  • There are no RCDs, or one RCD covering every power circuit, so one fault trips the whole house
  • The power trips when you run the kettle and toaster together
  • There are no spare poles for a new circuit
  • You’ve noticed scorch marks, buzzing or a burning smell
  • You’re adding an EV charger, air con or solar

If you tick one or two of these, it’s worth a look. It doesn’t always mean a full upgrade.

Older Homes

Asbestos Boards in Older Homes

A lot of older Perth homes have the switchboard mounted on a panel that contains asbestos. It’s usually stamped on the back of the panel, and we can confirm it on site. Please don’t pull the board apart to check.

An asbestos panel can’t just be drilled or modified to fit new gear. If yours is asbestos, we’ll tell you upfront and plan the upgrade around it, so it’s handled safely and properly from the start.

Pricing

What Affects the Cost

  • Number of circuits. More circuits means more breakers and more work.
  • An asbestos panel. It changes how the job is done.
  • The meter box and mains. If they’re old or damaged, they may need work too.
  • RCDs or RCBOs. Individual RCBOs on each circuit cost a bit more, but a fault only trips the circuit it’s on.
  • Extras. Surge protection, or new circuits for an EV charger or air con.

Every board is different, so the easiest way to get a price is to send us a photo of yours with the door open. We’ll quote it over the phone, and confirm it in writing before any work starts.

Common Questions

Switchboard Upgrade FAQs

How long does a switchboard upgrade take? +

Most are done in a day. The power is off while the board is changed over, and we'll tell you beforehand roughly how long so you can plan around it.

Does my board actually need upgrading? +

Not always. If your board has RCD protection, no old fuses and room for what you want to add, it may be fine as it is. Send us a photo and we'll tell you honestly.

I'm getting an EV charger. Will I need a new board? +

Sometimes. A charger needs its own circuit and RCD protection, so it comes down to whether your board has a spare pole and is in good shape. Our guide on EV chargers and switchboards explains what to look for.

Is there a call-out fee? +

No. Most switchboards can be quoted from a photo, and you'll get the price in writing before any work starts.
