A home’s electrical system is like its nervous system — and the switchboard is the control centre. If you’re living in an older property in Sydney’s Northern Beaches, there’s a good chance your switchboard is due for an upgrade. Many homes in suburbs like Manly, Dee Why, and Balgowlah were built decades ago, and their electrical systems weren’t designed to power modern households full of appliances, devices, and electric vehicles.
An outdated or faulty switchboard isn’t just an inconvenience — it’s a real safety risk. Below are 7 clear signs it’s time to upgrade your switchboard.
1. Your Power Trips Frequently Does your power cut out when you run too many appliances at once — like the heater and dishwasher? Frequent circuit breaker trips are a sign your system can’t keep up with demand. New switchboards are designed to handle higher loads, meaning no more annoying blackouts.
2. There Are No Safety Switches If your board doesn’t have a safety switch (also known as a Residual Current Device or RCD), your system is non-compliant with current NSW safety regulations. Safety switches cut power instantly when they detect a fault, protecting you from shocks and electrical fires.
3. You Still Have Ceramic Fuses Old-style ceramic fuses are a major red flag. Not only are they outdated and potentially unsafe, but they also don’t offer the same level of protection as modern circuit breakers. If you’re still replacing fuse wire, it’s time for an upgrade.
4. Buzzing, Sparks, or Burning Smells Any of these symptoms can indicate overheating, poor connections, or internal faults — all of which can lead to fire. A buzzing switchboard is not normal. Call a licensed electrician immediately.
5. You’re Renovating or Adding New Appliances Adding a new kitchen, aircon system, or even an EV charger? Your existing board may not have the capacity to safely power everything. A switchboard upgrade ensures your system can handle it without risk.
6. Lights Flicker or Power Is Inconsistent Inconsistent power can mean your circuits are overloaded or that the board is struggling to distribute power efficiently. Flickering lights can be more than just a bulb issue — they might be a warning sign.
7. Your Home Is Over 20 Years Old If your home hasn’t had an electrical upgrade in 20+ years, your switchboard is almost certainly outdated. Electrical standards have changed dramatically, and old boards can pose serious risks to your family and property.

How Much Does a Switchboard Upgrade Cost in Sydney?
In the Northern Beaches area, most switchboard upgrades cost between $1800 and $4000, depending on the size of the board, number of circuits, and whether any rewiring is needed.
It’s a one-off investment that can:
- Prevent electrical fires
- Lower your insurance risk
- Increase home value
- Power more modern appliances
Why Northern Beaches Homes Are at Higher Risk
Many homes in Manly, Dee Why, and surrounding suburbs were built in the 1950s–80s. These properties often still have original boards, old wiring, and no RCD protection. Combined with modern power usage, the risk of overloading or faults increases.
If you’ve added new appliances, renovated, or noticed electrical quirks — it’s worth getting a checkup.
