Most home rewiring jobs in Australia take between 3 and 10 days to complete. Smaller homes or units can be done in as little as 2 days, while large or older properties in areas like Woy Woy and Gosford, NSW can take up to two weeks. This guide covers what affects the timeline, what happens at each stage, and how to plan for the work.
Understand What Affects How Long Home Rewiring Takes
No two rewiring jobs are the same. The timeline depends on several factors that your electrician will assess before starting work.
- Home size: A 2-bedroom unit takes far less time than a 5-bedroom house with multiple living areas.
- Age of the property: Older homes, especially those built before 1980, often have outdated wiring systems that take longer to replace safely.
- Wall construction: Brick veneer homes are harder to run cable through than timber-framed homes, adding time to the job.
- Number of circuits: More circuits mean more work. Homes with dedicated circuits for air conditioning, EV chargers, or solar systems add complexity.
- Accessibility: If your roof cavity or subfloor is hard to access, cable runs take longer to complete.
- Inspection scheduling: In NSW, a licensed electrician must lodge a compliance certificate. Inspection timing can add a day or two to the overall project.
ABC Electrical always does a thorough site assessment before quoting so you get an accurate timeline, not a guess.
Compare Rewiring Timelines by Home Size
The most reliable way to estimate how long rewiring will take is to look at your home’s size and layout. Here is a general guide based on typical jobs we see across the Central Coast.
| Home Size | Estimated Rewiring Time | Notes |
|---|---|---|
| 1-2 bedroom unit or flat | 1 to 3 days | Straightforward layout, fewer circuits |
| 3 bedroom house | 3 to 5 days | Standard Central Coast residential home |
| 4 bedroom house | 5 to 7 days | More circuits, possibly multiple living areas |
| 5+ bedroom house | 7 to 10 days | Complex layouts, more cable runs required |
| Older or heritage property | 10 to 14 days | Existing wiring removal adds significant time |
These ranges are guides only. A property with a granny flat, workshop, or pool equipment will take longer than a standard home of the same size.
Explore What Happens at Each Stage of a Rewiring Job
Understanding the stages helps you plan around the work and know what to expect each day. Rewiring is not just pulling old wire and putting new wire in. It is a structured process.
- Site assessment and planning: Your electrician inspects the existing wiring, identifies hazards, and plans the new circuit layout. This usually happens before the job starts.
- Isolation and safety setup: The power is isolated and safe work procedures are put in place before any cable is touched.
- Old wiring removal: Existing cables, outlets, switches, and the old switchboard are carefully removed. This can be dusty and disruptive.
- New cable installation: Fresh TPS cable is run through wall cavities, roof spaces, and subfloors to all new outlet and switch positions.
- Switchboard upgrade: A new consumer mains switchboard with safety switches (RCDs) and circuit breakers is installed. This is required under Australian standards.
- Fitting off: All power points, light switches, light fittings, and other devices are connected and fitted.
- Testing and inspection: The entire system is tested, and a Certificate of Compliance for Electrical Work (CCEW) is issued as required by NSW Fair Trading.
Each stage flows into the next. Delays at one stage, like discovering asbestos in wall cavities, can push back the rest of the schedule.
Know How Woy Woy and Gosford Properties Can Affect Timelines
Properties on the Central Coast have some specific characteristics that affect rewiring timelines. Woy Woy in particular has a large number of older fibro and weatherboard homes built in the 1950s through to the 1970s.
These homes often have original rubber-sheathed or cloth-covered wiring that is brittle and difficult to remove without damaging wall linings. That adds time compared to a newer brick home in a suburb like East Gosford.
The coastal environment also matters. Salt air in areas close to Brisbane Water can corrode older wiring and switchboard components faster than inland properties. This sometimes means more extensive replacement work is needed once the walls are opened up.
Many Woy Woy homes also have limited roof cavity access due to low-pitched roofs, which slows down cable runs significantly. ABC Electrical works across the Woy Woy, Gosford, and broader Central Coast area regularly, so we know how to plan around these local conditions.
Compare Partial vs Full Rewiring Timelines
Not every job is a full rewiring. Sometimes only part of a home needs attention. Here is how timelines compare between partial and full rewiring work.
| Scope of Work | Typical Timeline | Common Reason |
|---|---|---|
| Single circuit replacement | Half a day to 1 day | Faulty circuit, renovation, new appliance |
| Partial rewire (one area) | 1 to 3 days | Kitchen or bathroom renovation |
| Switchboard upgrade only | Half a day to 1 day | No safety switches, outdated board |
| Full house rewire (3 bed) | 3 to 5 days | Whole-home upgrade, pre-sale, insurance |
| Full rewire with solar or EV prep | 5 to 8 days | Future-proofing for new technology |
A partial rewire can sometimes take longer per circuit than a full rewire. This is because the electrician must work carefully around existing wiring that is staying in place.
Plan for Disruption During a Home Rewiring Project
Rewiring is one of the more disruptive electrical jobs. Here is what you should plan for to make the process smoother.
- Power outages: Expect your power to be off for most of each working day. Plan for meals, device charging, and refrigerated food storage.
- Temporary accommodation: For full rewires lasting more than 5 days, some families choose to stay elsewhere. This is worth considering if you have young children or work from home.
- Furniture and wall access: Electricians need clear access to walls and roof spaces. Move furniture away from walls before the job starts to avoid delays.
- Dust and minor wall damage: Some patching of walls is normal after cable runs. Your electrician will make access holes as small as possible, but some patching will likely be needed.
- Pet and child safety: Keep children and pets away from the work area throughout the job. Power tools, open walls, and cable scraps are hazards.
- Inspection day: Allow at least one additional day for the compliance inspection process. In NSW, this must happen before power is restored permanently.
Good planning before the job starts saves frustration once it is underway. Your electrician should walk you through what to expect at the initial assessment.
FAQs on How Long Home Rewiring Takes
Can I stay in my home while it is being rewired?
Yes, most homeowners stay in their home during rewiring. However, you will be without power during working hours and some areas of your home will be inaccessible. For jobs lasting more than a week, temporary accommodation is worth considering for comfort.
Does rewiring damage my walls and ceilings?
Some minor damage is unavoidable. Electricians make small access holes to run cables, particularly in walls. These are usually patched by a plasterer after the job. A good electrician will minimise damage and let you know what to expect upfront.
Do I need a permit or inspection for home rewiring in NSW?
Yes. In NSW, all rewiring work must be done by a licensed electrician who issues a Certificate of Compliance for Electrical Work (CCEW). This is required by NSW Fair Trading and ensures the work meets Australian standard AS/NZS 3000. Do not use unlicensed tradespeople for rewiring work.
How do I know if my Woy Woy home needs rewiring?
Common signs include frequently tripping circuit breakers, flickering lights, discoloured or warm power points, burning smells, or wiring that is older than 25 to 30 years. If your home still has old ceramic fuse holders instead of modern circuit breakers, a rewire is strongly recommended.
How long does a switchboard upgrade take if I only need that?
A switchboard upgrade on its own typically takes half a day to a full day. This includes fitting a new consumer mains board, installing RCD safety switches, and circuit breakers that comply with current Australian standards. It is one of the quickest ways to improve electrical safety in an older home.
Will rewiring my home add value before I sell?
Yes, updated wiring is a selling point and can satisfy building inspection requirements. Many buyers and their conveyancers in the Gosford and Woy Woy area specifically ask about the age of wiring and whether safety switches are installed. Fresh wiring with a compliance certificate gives buyers confidence.
Wrap Up and Next Steps
