Yes, you can add more power points to an existing home, and it is one of the most common electrical upgrades Adelaide homeowners request. The cost typically ranges from $150 to $400 per power point, depending on location, wall type, and access to existing wiring. This article covers the process, costs, safety rules, and what to expect when upgrading your home’s power points.
Understand Why Homeowners Add More Power Points
Older homes across suburbs like Glenelg, Plympton, and Unley were built long before households ran multiple TVs, laptops, phone chargers, and kitchen appliances simultaneously. What was enough in the 1970s or 1980s simply is not enough today.
Adding power points is not just about convenience. It is also a safety upgrade. Overloading extension cords and double adapters is a leading cause of electrical fires in Australian homes. Getting properly installed power points removes that risk entirely.
- Too many extension leads running across floors or under rugs
- Double adapters on every outlet in a room
- Constantly unplugging one device to use another
- New appliances with nowhere practical to plug in
- Home office setups that need dedicated outlets
- Outdoor entertaining areas with no nearby power
- Kitchen renovations requiring more bench-level outlets
If any of these sound familiar, adding power points is a straightforward fix that a licensed electrician can handle in a single visit for most rooms.
Know the Rules: Who Can Install Power Points in South Australia
In South Australia, all electrical work must be carried out by a licensed electrician. This is not optional. It is the law under the Electricity Act 1996 and the relevant Australian Standards (AS/NZS 3000, known as the Wiring Rules).
DIY electrical work is illegal and dangerous. Even replacing a power point yourself can result in fines, void your home insurance, and create serious safety hazards. Every electrical installation must also be certified with a Certificate of Compliance upon completion.
- Only a licensed electrician can legally add or move power points
- A Certificate of Compliance must be issued for the work
- Work must comply with AS/NZS 3000 Wiring Rules
- Your home insurer may reject claims for damage caused by unlicensed work
- Rental properties in South Australia require compliant wiring for landlord obligations

Compare the Cost of Adding Power Points in Adelaide
Pricing for power point installation varies depending on several factors. The main variables are how close the new outlet is to existing wiring, the wall type (plasterboard vs. double brick), and whether any switchboard upgrades are needed.
| Scenario | Estimated Cost Range | Notes |
|---|---|---|
| Single power point, easy access | $150 to $220 | Near existing circuit, plasterboard wall |
| Single power point, moderate access | $220 to $300 | Longer cable run or partial brick wall |
| Double brick wall installation | $300 to $450+ | Requires chasing or surface conduit |
| Outdoor weatherproof power point | $250 to $400 | Needs IP-rated outlet and outdoor cabling |
| Multiple power points (3 or more) | $120 to $200 per point | Economies of scale on call-out and labour |
| USB power point upgrade | $180 to $280 | Replaces standard outlet with USB-A or USB-C ports |
These are typical Adelaide market rates as of 2025. Prices can shift based on your specific home layout and any additional work required. Getting a quote from H. Irwin Electrical gives you a clear, upfront number with no surprises.
Understand the Installation Process Step by Step
Knowing what actually happens during a power point installation helps you plan better and set realistic expectations. A standard installation on a single-storey plasterboard home is usually completed in one to two hours per outlet.
Here is how the process typically works when you book with a licensed electrician:
- Site assessment: The electrician checks your switchboard capacity, identifies the nearest existing circuit, and confirms the wall type and cable routing path.
- Circuit check: They confirm the existing circuit can handle the additional load safely, or recommend a new circuit if needed.
- Cable routing: Cables are routed through wall cavities, under floors, or via surface conduit depending on the home’s construction.
- Outlet installation: The new power point is fitted, wired, and secured to the wall with the correct back plate and cover.
- Testing: The outlet is tested for correct polarity, earth continuity, and safe operation before the job is signed off.
- Certification: A Certificate of Compliance is issued and provided to you as the homeowner.
For double brick homes common in suburbs like Hyde Park, North Adelaide, and Kurralta Park, the process takes longer because cables must be chased into the masonry or run in conduit along the surface. Your electrician will discuss the best approach for your specific home.
Explore Common Locations Where Adelaide Homeowners Add Power Points
Some rooms and areas come up again and again when homeowners book power point installations across Adelaide’s southern and western suburbs. Understanding the common use cases helps you plan your own upgrade properly.
| Location | Common Reason | Special Considerations |
|---|---|---|
| Kitchen benchtop | Appliances, coffee machines, toasters | Must be minimum 150mm from sink |
| Home office or study | Computers, monitors, desk lamps | Consider USB outlets or data points |
| Master bedroom | Phone charging, bedside lamps | Position near bed head height |
| Garage or workshop | Power tools, compressors | May need 15A heavy-duty outlet |
| Outdoor entertaining area | BBQ appliances, lighting, speakers | Must be weatherproof, IP56 rated |
| Laundry | Washing machine, dryer | Check if dedicated circuit is needed |
| Living room | TV, gaming consoles, soundbars | Consider in-wall cable management |
If you live in Henley Beach, West Beach, or Somerton Park, outdoor power points are especially popular for alfresco entertaining areas. Coastal conditions mean your electrician should use stainless or UV-rated fittings to handle the salt air environment.
Identify When Your Switchboard Might Need an Upgrade Too
Sometimes adding power points reveals a bigger issue. Older homes in Glandore, Beverley, Fulham, and Prospect often still have original switchboards with ceramic fuses rather than modern circuit breakers. These boards may not safely support additional circuits.
Signs your switchboard might need attention before or alongside adding power points include:
- Ceramic fuse holders instead of circuit breakers
- No safety switches (RCDs) installed on power or lighting circuits
- Breakers that trip regularly when appliances are running
- Burn marks, discolouration, or a burning smell near the board
- The board has no room for additional circuit breakers
- Your home is more than 30 years old and has never had electrical work done
A switchboard upgrade typically costs between $800 and $2,500 depending on size and complexity. It is not always required, but it is worth having your electrician assess it at the same time as your power point installation.
H. Irwin Electrical carries out switchboard assessments as part of power point consultations. If an upgrade is needed, you will get a clear quote before any work begins.
FAQs on Adding Power Points to an Existing Home
How many power points can I add to my home?
There is no fixed limit on the total number of power points in a home, but each circuit has a maximum safe load capacity. A licensed electrician will assess your existing circuits and advise whether new points can be added to current circuits or whether a new circuit is needed. Most homes can comfortably accommodate additional outlets with minimal switchboard work.
Can I add a power point in a bathroom or near a sink?
Bathroom power points are heavily restricted under Australian wiring rules. Standard outlets cannot be installed within 1.25 metres of a water source like a sink or shower. Shaver outlets with isolation transformers are permitted in bathrooms. A licensed electrician will confirm what is allowed in your specific bathroom layout.
How long does it take to install a new power point?
For a straightforward installation in a plasterboard-walled home, a single power point typically takes between one and two hours. Double brick walls take longer due to cable routing. If you are having multiple outlets added in one visit, the total job time increases but the per-point labour cost usually drops.
Do I need council approval to add power points in Adelaide?
Adding standard power points does not require council approval in South Australia. However, the work must be done by a licensed electrician and certified with a Certificate of Compliance. Some larger electrical projects may require notification to the relevant authority, but routine power point additions do not fall into that category.
Will adding more power points increase my electricity bill?
Simply installing new power points does not increase your electricity bill. Your bill only increases if you actually plug in and run more appliances. The outlets themselves consume no power when nothing is connected to them, so there is no ongoing cost just from having more outlets available.
Can I get USB power points installed instead of standard ones?
Yes, USB power points are a popular upgrade and can be installed in place of or alongside standard outlets. They include built-in USB-A or USB-C charging ports, removing the need for wall adapters. They are especially popular in bedrooms, home offices, and kitchens. The cost is slightly higher than a standard outlet due to the fitting price, but the convenience is significant.
