House rewiring
Wiring installed before the 1960s was never meant to last this long. Rubber and cloth insulation goes brittle and crumbles, which is a shock and fire risk. We replace it with modern cable, room by room or all at once.

Short answer
A full rewire of a typical three-bedroom Sydney home costs about $9,000 to $18,000, depending on access, the number of points and the state of the walls. Partial rewiring of individual circuits typically costs $800 to $2,500 per circuit. Most homes stay liveable during the work.
Many Inner West and South Sydney terraces and bungalows still have sections of their original wiring. Even where a previous owner has upgraded part of the house, old cable often remains in the ceiling or under the floor.
We inspect and test first, so you know which circuits actually need replacing. If a full rewire isn’t necessary, we’ll say so.
Signs of old or failing wiring
- Black rubber or cloth-covered cable in the roof space or under the floor
- Round, brown or bakelite switches and power points
- Two-pin outlets with no earth
- Lights that flicker, or outlets that feel warm
- Repeated safety switch trips that point to insulation breaking down
- An insurer, building inspector or buyer has asked about the wiring
What it costs
We quote after an inspection because access and wall types vary so much.
| Job | Typical price | What changes the price |
|---|---|---|
| Inspection and insulation testing report | $180–$350 | Size of the home |
| Rewire a single circuit | $800–$2,500 | Number of points, access |
| Full rewire, two-bedroom home or unit | $7,000–$12,000 | Access and wall types |
| Full rewire, three-bedroom home | $9,000–$18,000 | Access, number of points, switchboard |

Why it matters
Old insulation can’t be repaired, only replaced. Rewiring brings the installation up to current AS/NZS 3000 requirements, adds earthing where it was missing, and puts every circuit on modern protection.
Rewiring is a good time to add the power points, data points and lighting you’ll want for the next 30 years, while the walls and ceilings are open.
FAQ
Common questions
Straight answers to what customers ask us most. Can’t see yours? Call us and talk to an electrician, not a call centre.
Do you need to cut into walls?
Less than most people expect. We use roof and underfloor access wherever possible. Some small openings may be needed, and we’ll tell you where before we start.
How long does a full rewire take?
Most three-bedroom homes take four to eight working days, depending on access and the number of points.
Can I stay in the house?
Usually yes. We work circuit by circuit and restore power each evening.
