Consumer Mains Upgrades for Modern Homes

Your consumer mains carry electricity from the network connection to your switchboard, making them one of the most important parts of your electrical system. As homes continue adding air conditioning, EV chargers, solar systems, batteries, and other high-demand appliances, older mains often become undersized or deteriorated, affecting both safety and performance.

Signs Your Supply Needs Upgrading

Many supply problems develop gradually before becoming major electrical issues.

Common signs include:

  • Frequent circuit breaker tripping
  • Lights dimming under heavy load
  • Voltage drop throughout the home
  • Ageing or damaged consumer mains
  • Installing EV chargers or large appliances
  • Defect notices from your distributor

Upgrading early helps improve reliability while reducing future safety risks.

What We Do

Signs You Need a Mains Upgrade

Undersized or ageing mains show clear warning signs. Catching them early avoids both safety risks and defect notices.

Frequent Tripping

Breakers tripping under normal load often point to mains that can't handle your demand.

Dimming or Flickering

Lights dimming when appliances start can signal voltage drop from undersized mains.

Adding Big Loads

Installing air con, solar, or an EV charger may require a mains upgrade to cope.

Old or Damaged Cabling

Worn, brittle, or undersized mains are a safety risk and a common defect cause.

Why Choose Us for Your Supply Upgrade

A mains upgrade affects the safety and reliability of your whole home. It's worth getting right. Here is what you get with us:

  • ASP accredited Level 2 — authorised to upgrade mains and supply, including the network connection side.
  • Future-proofed — we size your upgrade for the load you'll have, not just the load you have now.
  • Lifetime labour warranty — every upgrade is backed by our lifetime labour guarantee.

Power that keeps up with your home

Modern homes draw far more power than they did even a decade ago. Between ducted air conditioning, induction cooktops, solar, batteries, and EV chargers, an older supply can quickly become the bottleneck. Upgrading your mains and supply removes that limit, so everything runs smoothly and safely without nuisance tripping or voltage issues. A supply upgrade is frequently done alongside a switchboard upgrade, since the two work together to handle your home's load safely, and we can assess and quote both at once so you get a complete, compliant setup in a single job.
