How Much Does It Cost to Rewire a House in South Australia?

Written By ben Feltus

Wondering if your home’s wiring is up to scratch — or how much it’ll cost to upgrade it? In this guide, I’ll break down the real-world costs of rewiring, when it’s worth doing, and what South Australian homeowners can expect from the process.

🔥 Why You Might Need to Rewire

If your home was built before the 1980s, there’s a good chance the wiring is:

  • Unprotected

  • Deteriorating

  • Or just plain unsafe

We’re talking about rubber, cloth or cotton-insulated wiring that can crack, expose live conductors, or even cause fires.

⚠️ Signs Your Wiring Is Outdated

  • Power points or switches are warm to touch

  • Lights flicker or dim when appliances are turned on

  • The fuse box trips constantly

  • You smell burning plastic near sockets

  • Outlets are missing earth pins or feel loose

  • Wiring in the roof looks brittle, sticky, or discoloured

If you’ve noticed any of these, get it checked ASAP — especially if you’ve recently bought or plan to rent the property out.

💸 What Does It Cost to Rewire a House in SA?

Rewiring isn’t one-size-fits-all — it depends on your home’s size, access, and layout — but here’s a realistic price guide:

Home SizeEstimated Rewiring Cost (SA)Small home (2 bed, 1 bath)$4,000 – $6,000Average home (3 bed, 1–2 bath)$6,500 – $9,000Large or two-storey home$9,000 – $15,000+

💡 Includes:

  • New cabling

  • Updated switchboard with RCBOs

  • Compliance upgrades

  • Labour and materials

  • Certification

⚠️ Prices can increase if walls are hard to access, asbestos is present, or older add-ons (like detached sheds) also need rewiring.

🏘️ Suburbs Where We See This Most

Many homes in Adelaide’s north still have wiring from the 60s–80s.

If you’re in one of these areas, you may be at risk:

Northern Suburbs:

  • Elizabeth (all areas)

  • Salisbury North, East, and Park

  • Craigmore

  • Smithfield

  • Munno Para

  • Hillbank

Surrounding Rural Towns:

  • Gawler

  • Kapunda

  • Freeling

  • Roseworthy

  • Two Wells

  • Angle Vale

  • Barossa Valley homes (especially original builds)

⚠️ Homes in these areas are often 30–50 years old and haven’t had electrical upgrades since being built.

🔧 What’s Involved in a Rewiring Job?

When we rewire a house, we:

  • Disconnect power and assess all circuits

  • Remove unsafe or non-compliant cable

  • Install new cable throughout the home

  • Upgrade the switchboard with RCBOs and modern safety protections

  • Restore power and test everything

  • Issue a Certificate of Compliance (COC)

We also make sure everything is clean, patched up, and left how we found it — or better.

🔌 What’s an RCBO?

An RCBO (Residual Current Breaker with Overcurrent) protects you from both:

  • Electric shocks (RCD function)

  • Circuit overloads (breaker function)

It’s the gold standard for electrical safety in Australian homes, and every circuit in your new switchboard should have one.
