Wiring, switchboard capacity and lighting decisions shape everything that comes after them in a renovation. Here is how Sydney homeowners can plan the electrical side before the walls are opened, so there are fewer surprises, delays and costly changes.

      ![Russo Electrical electrician assessing a home's electrical installation before a renovation](https://russoelectrical.com.au/wp-content/uploads/2026/11/Electrical-Safety-Inspection.webp)A pre-renovation assessment checks the switchboard, wiring and capacity against your plans.

      
        Key takeaways
        
## The short version

        
- **Start with an electrical assessment:** a licensed electrician checks your switchboard, wiring and capacity against your plans before any wall is opened.
- **Check switchboard capacity early:** every new appliance, room and light adds load. Upgrade before new circuits go in if the switchboard is near its limit.
- **Deal with ageing wiring while walls are open:** partial or whole-house rewiring is far easier and cheaper before plasterboard goes up.
- **Plan circuits, power points and lighting on paper:** dedicated circuits, safety switch protection and lighting zones should be settled before rough-in.
- **Build in future-ready upgrades:** conduit for an EV charger, spare switchboard space and surge protection cost little now.
- **Get it tested and certified:** in NSW, your licensed electrician lodges a Certificate of Compliance for Electrical Work (CCEW).
- **Budget with a contingency:** hidden conditions behind walls are common, so keep a separate electrical reserve.

      

      
      
        
## Introduction

        
### The electrical oversight that derails renovations

        
Electrical renovations often go hand in hand with larger building projects, but many upgrades happen on their own. As homes age and demand grows, the home electrical system needs attention to keep up with modern power needs.

        
Skip that attention, and a home renovation can stall. Surprises behind the walls lead to delays and costly changes.

        
### Why wiring decisions come before finishes

        
Electrical wiring, switchboard capacity and lighting design shape everything that follows. Walls, cabinets and flooring all depend on them.

        
Common reasons homeowners start an electrical renovation include:

        
- Upgrading ageing wiring
- Adding home automation features
- Improving lighting
- Addressing safety hazards

        
A well-planned electrical renovation improves comfort, supports modern technology and reduces the risk tied to outdated systems. Preparation is the key to a successful outcome.

      

      
      
        
## Getting a professional electrical assessment first

        
Before any wall is opened, have a licensed electrician assess your home's electrical system. An assessment shows what the system can support and what must change before construction begins.

        
It also gives your builder and other trades accurate information. Plans built on guesses are the ones that fall apart.

        
### What the electrician checks

        
A thorough assessment looks at the full system, not just the rooms you plan to renovate. The goal is to match the existing installation to the demands your project will add.

        
Expect the electrician to review:

        
- The [switchboard](https://russoelectrical.com.au/services/switchboard-upgrade/), including its age, condition, circuit protection and capacity
- The type and condition of the wiring in accessible areas
- Power points, switches and light fittings for wear, damage or poor installation
- Signs of overloaded circuits, such as frequent tripping
- Earlier electrical work that may not meet current standards

        
Bring your renovation plans to the visit. The electrician can then judge whether the current system can carry the new kitchen, extension, granny flat or converted space you have in mind.

        
### Hidden hazards that surface behind walls

        
Some problems stay invisible until construction starts. Outdated wiring, overloaded switchboards and unsafe joins are common examples.

        
Older switchboards may not handle modern appliances, electronics and smart devices. An outdated or overloaded switchboard can cause frequent tripping and safety hazards such as electrical fires.

        
Finding these issues early changes the outcome. A hazard discovered during planning is a line item. The same hazard discovered mid-demolition is a schedule problem.

        
          
| When the issue is found | What it usually means for your project |
| --- | --- |
| Before construction | Time to plan, budget and schedule the fix alongside other work |
| During construction | Work stops, trades wait, and changes are made under pressure |
| After finishes are installed | Finished walls and surfaces may need to be reopened |

        

        
### Earthing, bonding and compliance

        
Safe wiring depends on more than good cable. Earthing and bonding give fault current a safe path, which protects people and equipment.

        
In Australia, the [AS/NZS 3000 Wiring Rules](https://www.standards.org.au/standards-catalogue/standard-details?designation=as-nzs-3000) set the baseline for how electrical installation work must be done. Your electrician checks the existing installation against them and flags anything that falls short.

        
Compliance matters most when you add circuits, move walls or change the load. New and altered work generally needs to meet current requirements, so identify the gaps now. This early step is the foundation for safe, compliant work that supports both current and future needs. You are planning for how the home will be used after the renovation, not just today.

        
Ask the electrician for a written summary of findings. Use it to rank the work:

        
1. Safety issues that must be corrected before anything else
2. Capacity limits that affect your renovation plans
3. Upgrades that make sense while walls are open
4. Items that can wait for a later project

        
That list becomes the starting point for decisions about the switchboard, wiring and circuits that follow.

      

      
      
        
## Checking whether your switchboard has enough capacity

        
Your switchboard is the heart of your home's electrical system. Every circuit in the house runs from it, so its capacity sets the ceiling for what your renovation can add.

        
Check this before you finalise layouts or order appliances. A project that outgrows the switchboard will stall until the switchboard is sorted.

        
### Calculating the new load

        
Capacity is about total demand, not just the size of the switchboard. Your electrician reviews the load across the whole home and compares it to what the supply and switchboard can safely deliver. Our guide [Does my home have enough electrical capacity?](https://russoelectrical.com.au/does-my-home-have-enough-electrical-capacity/) explains this in more detail.

        
List every addition your renovation will bring. Give the electrician specifics, including brands or ratings if you have them.

        
- New appliances, such as an oven, [induction cooktop](https://russoelectrical.com.au/services/induction-cooktop-installation/) or dishwasher
- Added rooms, an extension or a granny flat
- Extra lighting, including LED downlight runs
- Smart devices, such as a smart thermostat or controls
- Possible future loads, such as an [EV charger](https://russoelectrical.com.au/services/ev-installation/) or solar panels

        
The electrician also looks at the circuit protection and whether the home still has old ceramic fuses. Cable condition and earth connections factor in as well, since a switchboard is only as safe as what connects to it.

        
A proper calculation tells you one of two things. Either the switchboard can absorb the new circuits, or it needs an upgrade before they go in.

        
### Signs your switchboard is maxed out

        
Your home often shows warning signs before a formal calculation does. These suggest the system is struggling with current use:

        
- Flickering lights
- Frequent tripping
- Warm power points
- Circuits that seem overloaded

        **Don't treat these as minor annoyances.** They point to safety hazards, including fire risk. If you notice any of them, tell the electrician during the assessment, or book our [switchboard support service](https://russoelectrical.com.au/services/switchboard-support/). Adding renovation load on top of an already strained switchboard raises the risk.
        
If your switchboard is near capacity, a switchboard upgrade may be needed before new circuits are added. In many cases, it is the only way to meet today's electrical needs.

        
### Upgrading a switchboard with or without rewiring

        
A common question is whether you can upgrade the switchboard without rewiring the house. Often the answer depends on the condition of the wiring, not the switchboard itself.

        
The switchboard and the circuit wiring are separate parts of the system. Your electrician inspects both and tells you whether one can be replaced without touching the other.

        
          
| Situation | Likely approach |
| --- | --- |
| Switchboard is undersized, wiring is in good condition | Switchboard upgrade alone, with new circuits added as needed |
| Switchboard is fine, wiring is ageing or unsafe | Targeted rewiring of the affected circuits |
| Both are outdated or overloaded | Switchboard upgrade combined with rewiring, planned together |

        
        
A modern switchboard gives you real benefits beyond the immediate project:

        
- **Supports modern demands:** it can take the additional circuits that new appliances or added rooms require.
- **Safer protection:** modern circuit breakers and safety switches (RCDs) lower the chance of fire and electric shock.
- **Ready for what's next:** it prepares the home for add-ons like EV chargers or solar panels.

        
Schedule the switchboard work early. Everything downstream, from new circuits to testing, depends on it being done first. See a real example in our [Gladesville switchboard upgrade](https://russoelectrical.com.au/case-studies/switchboard-upgrade-gladesville/).

        
Whether the work is a switchboard upgrade, a repair or new electrical installation, have a licensed electrical contractor handle it. The switchboard is not a place for guesswork.

      

      
      
        
## Deciding what to do about ageing wiring

        
Switchboard capacity is only half the picture. The wiring inside your walls carries every watt your renovation adds, and older wiring was never built for modern demand.

        
If your home was built decades ago, it may still have outdated wiring. Deciding how much of it to replace is one of the biggest choices in an electrical renovation.

        
### Older wiring found in Sydney homes

        
Older cable types are not only inefficient. As their insulation ages, they can also pose serious safety risks, including fire hazards. Your electrician identifies what you have during the assessment. Each type raises different concerns:

        
- **Rubber-insulated (VIR) wiring:** common in older homes. The rubber insulation becomes brittle and can crumble, exposing the conductors.
- **Cloth-covered or early insulated cable:** insulation that has aged and may no longer protect the conductors properly.
- **Old fuse boards and early alterations:** rewireable ceramic fuses and earlier DIY or non-compliant work that was never designed for today's appliance and electronics load.

        **Don't assume wiring is fine because the lights still work.** Ageing wiring often fails quietly, through overloaded circuits and worn components, before it fails visibly.

        
### Partial versus whole-house rewiring

        
Rewiring does not always mean replacing everything. Your electrician weighs the condition of the wiring against the scope of your renovation.

        
          
| Factor | Partial rewiring | Whole-house rewiring |
| --- | --- | --- |
| Best fit | Wiring is sound in most areas, with specific problem circuits | Outdated wiring runs throughout the home |
| Renovation scope | One or two rooms, a kitchen or a bathroom | Large renovation, extension or full gut |
| Main advantage | Focused work on the areas that need it | One consistent, modern system with no weak links |
| Main drawback | Older wiring remains elsewhere in the home | Broader scope and more disruption |

        
        
Ask your electrician to explain which circuits are at risk and why. A clear answer helps you decide whether a targeted fix covers your needs.

        
Scope also affects timing. Rewiring that happens before plasterboard and finishes go up is far easier to schedule than rewiring squeezed in afterwards.

        
### Using open walls as an opportunity

        
If your renovation exposes existing wiring, it is often the ideal time to replace outdated components. The walls are already open, so access is simple.

        
Waiting means opening finished walls later, which adds cost and repair work. Doing it now keeps the project on a single schedule. Use open walls to address several items at once:

        
- Replace ageing wiring that the inspection flagged
- Fix overloaded circuits by adding new ones
- Add power points where the layout was lacking
- Run new lines for lighting, including LED downlights
- Correct compliance concerns found during the assessment

        
Bring in a licensed electrical contractor before demolition starts. They can tell you which walls to open, which wiring to replace, and what the Wiring Rules require for the finished work.

        
The goal is simple: a home electrical system that safely supports the space you are building, not the one you had before.

## Planning circuits, power points and lighting

        
Once the wiring and switchboard questions are settled, design decisions take over. This is where electricity is matched to how you actually use each room.

        
New appliances, dedicated circuits, lighting and smart home technology all add load. A layout drawn before work begins keeps that load organised.

        
### Dedicated circuits for kitchens and appliances

        
Kitchens and bathrooms place the heaviest demands on your system. Discuss kitchen lighting, bathroom power points and any appliance that needs its own circuit.

        
A dedicated circuit serves one appliance or one purpose. It keeps a high-draw appliance from competing with everything else on the same circuit breaker. Think through which items in your renovation may need one:

        
- Large kitchen appliances you are adding or replacing, such as an oven or induction cooktop
- Equipment in a new room or extension
- Ceiling fans and automation features
- Future items such as EV chargers

        
Each new circuit needs space in your switchboard. Confirm that capacity early, so the layout does not outgrow the switchboard you just assessed. Share your appliance list with the electrician before ordering, because specifications can change what the circuit requires.

        
### Power point placement and safety switch protection

        
Too few power points is one of the most common problems in older homes. It often leads to extension leads and overloaded power boards.

        
Walk through each room and picture how you will live in it. Mark where furniture, benches, desks and electronics will sit.

        
- Place power points where you will use them, not where the old layout put them
- Add more than you think you need, since open walls make this inexpensive
- Plan for bathrooms, kitchens, laundries and outdoor areas with moisture in mind

        
Protection devices matter just as much as the number of power points. Your electrician applies the Wiring Rules to decide what protection is required and where.

        
          
| Protection type | What it guards against | Where it applies |
| --- | --- | --- |
| Safety switch (RCD) | Electric shock from earth leakage, including where electricity and water may meet | Required on new and altered circuits in homes, including power and lighting |
| Arc fault detection device (AFDD) | Fire risk from damaged or faulty wiring and loose connections | Optional for most homes; worth discussing for bedrooms and living areas |

        
        
Requirements depend on the work being done and the current edition of the Wiring Rules. Your electrician confirms what applies to your project.

        
### Lighting zones, dimmers and switches

        
Lighting design is easier to get right on paper than after the ceiling is closed. Renovations are a strong chance to rethink indoor and outdoor lighting together.

        
Start by dividing each room into zones based on purpose. A kitchen, for example, may need task lighting over benches, general lighting overhead and accent lighting elsewhere.

        
- General lighting for overall visibility
- Task lighting for work surfaces and reading areas
- Accent lighting for features you want to highlight
- Exterior lighting for entries, paths and safety

        
LED downlights need particular attention. Positions must be set before plasterboard goes up, and the ceiling framing above affects where they can go.

        
Dimmers and switches deserve the same planning. Decide where each switch sits, which fittings share a control, and whether any lights belong on a smart system. A few practical checks save headaches later:

        
1. Place switches at each entry point to a room.
2. Group fittings by zone so you can control them independently.
3. Confirm that dimmers match the type of light fitting you chose.
4. Mark every fitting location on a drawing for your electrician.

        
Finish this plan before demolition ends. A clear layout gives everyone one shared reference and keeps changes from piling up once the walls are closed.

      

      
      
        
## Building in future-ready upgrades

        
Open walls give you a rare chance to prepare your home electrical system for needs you do not have yet. Running extra conduit or cable now costs far less than cutting into finished surfaces later.

        
Modern households already depend on smart devices, home offices, electric vehicle chargers and high-efficiency appliances. Planning for that demand keeps your home current as technology changes.

        
### Smart home wiring and networking

        
Smart features are a common reason homeowners pursue an electrical renovation. Home automation, connected lighting and a smart thermostat all work better when the wiring behind them is planned in advance. Talk to your electrician about what each device needs before the walls close:

        
- Neutral wires at switch locations, so smart switches and dimmers can be installed
- Low-voltage wiring for a smart thermostat or controls
- Data cabling to rooms where a wired connection beats Wi-Fi
- A central location for networking equipment, with power points and ventilation nearby

        
Wired connections suit home offices and entertainment areas. Wi-Fi suits everything else, but its access points still need power and a clean cable path. Map LED downlights and smart controls together, so each fitting has the right control wiring from the start.

        
### EV charger and heat pump readiness

        
An EV charger and a heat pump (hot water or reverse-cycle air conditioning) are both large, steady loads. Neither fits comfortably on a switchboard that is already near its limit.

        
You do not have to buy either one during the renovation. You can prepare for them so adding them later is simple. If you are also moving away from gas, see our [gas-to-electric conversion](https://russoelectrical.com.au/services/gas-to-electric-conversion/) service.

        
          
| Item | What to prepare now | Question for your electrician |
| --- | --- | --- |
| EV charger | A dedicated circuit and a cable path to the garage or driveway | Does the switchboard and supply have room for the added load? |
| Heat pump | Space in the switchboard and a route to the equipment location | What circuit size will the chosen unit require? |

        
        
Equipment specifications drive the final circuit requirements. Choose a model, or at least a likely range, before the electrician sizes the wiring.

        
If your assessment showed limited capacity, decide on an upgrade now. Adding these loads to an undersized switchboard creates problems that are harder to fix after finishes are installed.

        
- Run conduit to the garage or exterior wall, even if the charger comes later
- Leave spare spaces in the switchboard for future circuits
- Record where every new cable runs, so you can find it later

        
### Whole-home surge protection

        
More electronics mean more to lose in a voltage spike. Appliances, computers and smart devices all contain sensitive components.

        
A surge-protected power board protects what is plugged into it. Whole-home surge protection is installed at the switchboard and covers the circuits connected to it.

        
- Switchboard-level protection covers hardwired equipment that power boards cannot reach
- Surge-protected power boards still add a second layer for sensitive electronics
- Installation is simplest when the switchboard is already being worked on

        
If you are upgrading the switchboard, ask your electrician to include surge protection in the same visit. It is a small addition to an existing job. Whole-home protection does not replace proper earthing and bonding. It works alongside them, so make sure the assessment covered both.

        
          
          
Every conduit run, spare switchboard space and extra cable you add during a renovation is an upgrade you won't have to open the walls for again.

        
        
Write your future-ready decisions into the same layout drawing as your power points and lighting. One shared plan keeps homeowners, builders and electricians working from the same information.

      

      
      
        
## Compliance, inspections and the rules in NSW

        
Electrical work is regulated for a reason. Errors inside walls can sit unnoticed for years before they cause a fault or a fire.

        
Compliance paperwork and testing give you a record that the work meets current standards. They also protect you when you sell the home or make an insurance claim.

        
### What NSW requires for electrical work

        
In NSW, electrical installation work must be done by a licensed electrician. For most work, the electrician must test it and lodge a **Certificate of Compliance for Electrical Work (CCEW)** with [NSW Fair Trading](https://www.fairtrading.nsw.gov.au/), and give you a copy.

        
Work that commonly needs a CCEW includes:

        
- A switchboard upgrade or replacement
- Rewiring, whole-house or partial
- New circuits for kitchens, extensions or granny flats
- Electrical installation for an EV charger or heat pump
- Major lighting changes, such as new LED downlights across several rooms

        
Work on the service connection, consumer mains or metering involves your local network, such as [Ausgrid](https://www.ausgrid.com.au/) or [Endeavour Energy](https://www.endeavourenergy.com.au/), and may need an Accredited Service Provider. The building work in your renovation may also need council or certifier approval. Ask rather than assume.

        
### Inspection and testing stages during a renovation

        
Some work has to be checked before it disappears behind plasterboard. Plan your renovation schedule around these checkpoints:

        
          
| Stage | What happens | Why timing matters |
| --- | --- | --- |
| Rough-in | Cable runs, boxes, switchboard connections and circuit layout are completed while walls are open | Linings should not go up until the electrician has finished rough-in |
| Switchboard and supply | Switchboard installation, earthing, bonding and protection; any network or metering work | Often needed before power is reconnected |
| Fit-off and testing | Devices and fittings installed; insulation, earth continuity, polarity and safety switch tests | The CCEW is lodged once the work passes testing |

        
        
Your electrician should coordinate each stage with your builder and tell you what to expect. Keep the work accessible until it is complete. Plasterboard, insulation and cabinets installed too early may have to come out.

        
### Why licensed electricians matter

        
An electrical renovation is not a good place to save money with an unqualified helper. Licensed electrical contractors know the Wiring Rules, issue the correct compliance paperwork and stand behind their work. Before you hire, check:

        
- A current NSW electrical contractor licence (you can check it through NSW Fair Trading)
- Public liability insurance
- That they will test the work and lodge a CCEW
- A written scope covering switchboard work, wiring and any repairs found during the assessment

        
Licensed professionals also coordinate well with other trades. Carpenters and plasterers depend on electricians finishing rough-in on schedule. For more tips, read [5 things to know before hiring an electrician in Sydney](https://russoelectrical.com.au/5-things-to-know-before-hiring-an-electrician-in-sydney/).

        **Be cautious if someone suggests skipping the paperwork to save time or cost.** Non-compliant or unlicensed work can create trouble with insurance claims, sale inspections and future projects.
        
          
          
A compliance certificate isn't paperwork for its own sake. It's the record that your home's electrical work was tested and meets the standard.

        
        
Treat compliance and testing as part of the plan, not an obstacle. Build them into your timeline and your contractor agreements from the start.

      

      
      
        
## Budgeting for electrical work

        
Electrical work often costs more than homeowners expect because so much of it is hidden. You pay for labour, materials, compliance and repairs to the walls and ceilings the electricians open.

        
A realistic budget starts with your assessment, not with a number you hope to hit.

        
### Typical costs for switchboard upgrades and rewiring

        
Costs vary by home size, construction type and access to the work area. Any fixed figure from an online article is a rough guess at best, so get written quotes from licensed electrical contractors based on your own assessment. These factors move the price most:

        
- The size and type of the new switchboard, and whether the supply or metering also needs work
- How many circuits you add, especially dedicated circuits for kitchens and large appliances
- How easy it is to reach the wiring (open walls cost less to work in than finished ones)
- Any network, metering or Accredited Service Provider work
- Repairs to plasterboard, plaster and paint after the electrical rough-in

        
Ask your electrician to price a switchboard-only upgrade and a switchboard-plus-rewiring option side by side.

        
### Comparing the main cost drivers

        
          
| Work item | What drives the price | How to control it |
| --- | --- | --- |
| Switchboard upgrade | Capacity, supply changes, earthing and bonding fixes | Size for future loads once, rather than upgrading twice |
| Rewiring | Number of rooms, wall access, type of wiring being replaced | Schedule it while walls are already open |
| New circuits and power points | Circuit count, run length, power point placement | Finalise the layout before rough-in begins |
| Lighting | Number of fittings, downlight cut-outs, switch and dimmer count | Settle your lighting design before ordering fittings |
| Add-ons | Surge protection, smart control wiring, EV charger or heat pump circuits | Install them during rough-in, not after finishes |

        
        
Changes made after the walls close are the most expensive ones. Make your decisions early.

        
### Contingency planning for surprises

        
Even a thorough assessment cannot see everything behind a wall. Once demolition starts, electricians may find damaged cable, undersized wiring or earlier amateur work that needs repair.

        
Set aside a separate contingency for electrical work. Don't fold it into the general renovation reserve, where it can get spent on finishes. Use these habits to keep surprises manageable:

        
- Ask for a written scope that lists what is included and what counts as an extra.
- Agree on how variations are priced and approved before work starts.
- Have the electrician photograph concealed conditions when walls are opened.
- Keep the schedule flexible enough to absorb a failed test or a delayed part.

        
A good contractor will explain a surprise before billing for it. If a quote looks far lower than the others, find out what it leaves out.

        
### Applying the 30% rule to renovation budgets

        
Homeowners often ask about the "30% rule" for home renovations. People apply it in different ways, so confirm which version your lender, designer or builder means before you rely on it. Use any percentage rule as a check on your plan, not a replacement for a quote:

        
- List every electrical item your project needs, from the switchboard to the last switch.
- Compare that list against your total renovation budget to see whether electrical work is getting a realistic share.
- Hold back a reserve on top of the quoted amount for hidden conditions.
- Revisit the numbers after the assessment and again after rough-in.

        **If the electrical total looks high, cut finishes before you cut safety.** Light fittings and decorative upgrades can wait. Switchboard capacity, sound wiring and compliance cannot. Budget for the system behind your walls first, because everything you see on top of it depends on that foundation.
      

      
      
        
## FAQ

        
          Can I upgrade my switchboard without rewiring my house?
          
Often, yes. A switchboard upgrade can go ahead on its own if the existing wiring passes inspection and is in good condition.

          
If the inspection finds outdated wiring, your electrician may recommend rewiring the affected circuits at the same time.

        
        
          What is the typical cost of a whole-house electrical upgrade?
          
There is no reliable single figure. Cost depends on the switchboard, the number of new circuits, wall access and any supply or metering work.

          
Get written quotes from licensed electrical contractors based on your own assessment. You can [request a quote](https://russoelectrical.com.au/request-a-quote/) from Russo Electrical.

        
        
          How much does it cost to rewire a typical Sydney house?
          
The price varies with the type of wiring being replaced, the number of rooms, the construction of the home and how easily the cable can be reached. Open walls lower the labour involved.

          
Ask for a quote that separates rewiring from switchboard work so you can compare each line.

        
        
          Do I need an electrical assessment before a small renovation?
          
Yes, if the project adds load or moves power points, lighting or appliances. An assessment shows whether your switchboard and wiring can support the change before construction begins.

        
        
          What paperwork do I need for electrical work in NSW?
          
For most electrical installation work, including switchboard upgrades, rewiring and new circuits, your licensed electrician tests the work and lodges a Certificate of Compliance for Electrical Work (CCEW) with NSW Fair Trading. Keep your copy. Work on the supply or metering may also involve your network provider.

        
        
          Should I add future-ready features now?
          
If your budget allows, yes. These are far cheaper to install while walls are open:

          
- Whole-home surge protection
- Extra downlight positions, switch boxes and conduit for an EV charger

          
Adding them after finishes are complete means opening walls again.

        
      

      
      
        
## Conclusion

        
A renovation succeeds or stalls on what sits behind the walls. Your home's electrical system sets the limits for every room you plan to change.

        
Start with an electrical assessment. It tells you whether your switchboard, wiring and circuits can carry the new load before demolition begins. Then work through the decisions in order:

        
1. Confirm switchboard capacity and plan an upgrade if the load demands it.
2. Decide how to handle ageing wiring while the walls are open.
3. Lay out circuits, power points and lighting before finishes are chosen.
4. Add future-ready features such as surge protection while access is easy.
5. Make sure the work is tested and certified at each stage.

        
Hire a licensed electrical contractor and keep a separate contingency for surprises.

        
Put safety and capacity ahead of fittings. Homeowners who plan the electrical work first spend less on changes later and finish with a system built for the years ahead.

{"@type":"Question","name":"How much does it cost to rewire a typical Sydney house?","acceptedAnswer":{"@type":"Answer","text":"The price varies with the type of wiring being replaced, the number of rooms, the construction of the home and how easily the cable can be reached. Ask for a quote that separates rewiring from switchboard work."}},
{"@type":"Question","name":"Do I need an electrical assessment before a small renovation?","acceptedAnswer":{"@type":"Answer","text":"Yes, if the project adds load or moves power points, lighting or appliances. An assessment shows whether your switchboard and wiring can support the change before construction begins."}},
{"@type":"Question","name":"What paperwork do I need for electrical work in NSW?","acceptedAnswer":{"@type":"Answer","text":"For most electrical installation work, your licensed electrician tests the work and lodges a Certificate of Compliance for Electrical Work (CCEW) with NSW Fair Trading. Work on the supply or metering may also involve your network provider."}},
{"@type":"Question","name":"Should I add future-ready features now?","acceptedAnswer":{"@type":"Answer","text":"If your budget allows, yes. Whole-home surge protection, extra downlight positions, switch boxes and conduit for an EV charger are far cheaper to install while walls are open."}}
