5 Signs It’s Time to Upgrade Your Switchboard

Your switchboard is the heart of your home’s electrical system—it distributes power to every outlet, light, and appliance. But if you’re dealing with flickering lights, tripped circuits, or an old fuse box, your switchboard might not be keeping up with modern power demands. Here are five key signs that it’s time for an upgrade.

1. Your Power Trips Frequently

Does your power cut out when you plug in the kettle while using the toaster? Do you constantly have to reset your circuit breakers?

Why this happens: Older switchboards weren’t built for today’s power-hungry homes. With modern appliances like heat pumps, induction cooktops, and EV chargers, older systems get overloaded fast.

What to do: If your switchboard can’t handle the load, it’s time for an upgrade. A modern switchboard with RCD protection (Residual Current Devices) can prevent overloads and electrical fires.

2. You Have an Old Fuse Box

If your home has ceramic fuses instead of circuit breakers, your switchboard is seriously outdated.

Warning signs:

  • You have to replace blown fuses manually.
  • Your fuses melt or burn out frequently.
  • Your wiring looks old and messy inside the switchboard.

Why upgrade? Modern switchboards with circuit breakers and safety switches are much safer—no more replacing fuses, and they trip instantly if there’s a fault.

3. Your Lights Flicker or Appliances Struggle

If your lights dim when you turn on the microwave or your appliances randomly lose power, your switchboard might not be distributing electricity properly.

Possible causes:

  • Loose or deteriorating wiring inside the switchboard.
  • An overloaded system that can’t handle modern electrical demands.
  • No surge protection, meaning voltage drops affect your home’s power supply.

A switchboard upgrade can fix this by balancing the electrical load properly.

4. You’re Renovating or Adding New Appliances

Planning a kitchen or bathroom renovation? Installing a heat pump, EV charger, or spa pool? Your switchboard needs to keep up with the extra load.

A typical older home’s switchboard wasn’t designed for:

  • Induction cooktops
  • Heat pumps
  • Home ventilation systems
  • EV chargers
  • Outdoor lighting & security cameras

Before adding more appliances, get your switchboard checked to avoid overloads and unexpected power cuts.

5. Your Switchboard Doesn’t Have Safety Switches (RCDs)

Safety switches (RCDs) instantly cut power if they detect a fault, reducing the risk of electrical shocks and fires. If your switchboard doesn’t have them, you’re at higher risk of electrical hazards.

How to check:

  • Modern switchboards have dedicated safety switches labeled as RCDs or RCBOs.
  • If yours only has fuses or circuit breakers, it may not offer full protection.
  • If you don’t know whether you have RCDs, it’s worth getting it checked.

Upgrading ensures your home meets modern safety standards and keeps your family protected.
