Electrical Wiring and Rewiring

Electrical Wiring and Rewiring Sydney

Safe, Compliant Wiring for New Builds and Older Properties.

The wiring inside your walls is something most people never think about — until something goes wrong. Older homes in Sydney, particularly those built before the 1980s, may still have original wiring that’s reached the end of its safe service life. Deteriorated insulation, undersized conductors, and missing earthing are all genuine safety risks.

BAC Group carries out electrical rewiring projects across Sydney, from partial circuit upgrades through to full house rewires. We work methodically to minimise disruption, and we’ll always explain exactly what we’re doing and why before we start.

When Rewiring Is Needed

Wiring is original to a pre-1980s home (rubber or fabric-insulated cable)
Frequent circuit breaker or fuse tripping that can’t be attributed to appliances
Evidence of previous DIY wiring or unlicensed work
Planning a renovation that requires circuit changes or extensions
Adding high-load appliances (EV chargers, large AC systems, spas)
Insurance company or conveyancer flagging the wiring as a risk

What's Involved

A full rewire involves replacing all branch circuit wiring with new TPS cable, installing a new switchboard with modern circuit breakers and RCDs, and ensuring all circuits are properly earthed and tested. We coordinate with you on timing — particularly for occupied homes — and stage the work to minimise the time without power.

Renovation Wiring

Renovating? We’re experienced in working alongside builders, tilers, and other trades on residential projects. We understand the importance of having rough-in complete before linings go on, and we’ll coordinate with your builder to make sure the electrical doesn’t hold up the timeline.

 Trustindex verifies that the original source of the review is Google.  We recently had BAC Electrical come out to do some electrical work in our home, and we couldn’t be happier with the service. From start to finish, Bashir (sorry if I have spelt it wrong) was professional, and extremely helpful. He took the time to explain everything clearly, which gave myself and my husband confidence in the work being done. His pricing was very fair, and the quality of the service and work was outstanding. It’s rare to find a company that’s both efficient and genuinely customer-focused, but BAC Electrical delivered on all fronts. We’re really happy with the results and wouldn’t hesitate to recommend them to anyone needing electrical work. Thank you BAC Electrical for delivering outstanding work!
