In modern workplaces, power and data infrastructure are not afterthoughts — they are the central nervous system of your business. Every device, every collaboration tool, every video call, and every transaction flows through your office’s electrical and network systems. Get it wrong, and you pay for it in downtime, rework, and frustrated staff. Get it right, and your office becomes a high-performance environment that supports growth for years to come.
Across Australia, the demand for smart, connected, technology-driven workplaces is accelerating. Businesses are fitting out new offices with open-plan layouts, hot-desking, hybrid work setups, and cloud-based systems — all of which place enormous demands on power and data infrastructure.
In this guide, we break down exactly what you need to include in a power and data plan for a new office fit-out — so you can make informed decisions, avoid expensive mistakes, and build a workplace that works.
Quick Cost Summary: What to Budget For
Before diving into the detail, here’s a snapshot of typical cost factors to help set expectations:
Factor | Typical Range (Australia) |
Basic power & data plan (small office, <10 staff) | $3,000 – $8,000 |
Mid-size office fit-out (10–50 staff) | $8,000 – $30,000 |

Note: Costs vary significantly by location, building conditions, and scope. Always request a detailed quote from a licensed electrical and data contractor.
What Is a Power & Data Plan?
A power and data plan is a detailed blueprint that maps out how electrical power and network connectivity will be distributed throughout your office. Think of it as the master document that guides your electrician, data cabling contractor, and IT team — ensuring every workstation, meeting room, and common area is properly serviced before walls are sealed and floors are laid.
At its core, a power and data plan covers two interconnected systems:
- Electrical layout — the placement of power points, GPOs (general purpose outlets), dedicated circuits, switchboard configuration, lighting, and backup power systems.
- Data/network layout — the placement of data points, network cabling routes, patch panel locations, server room or comms room design, and WiFi access point positions.
Together, these two plans form the foundation of every modern office fit-out. They inform the architectural drawings, guide the trades, and ultimately determine how efficiently your team can work on day one — and for the years ahead.
Why a Proper Plan Is Essential
Skipping or underinvesting in a power and data plan is one of the most common — and costly — mistakes made during office fit-outs. Here’s why getting it right from the start matters:
Prevents expensive redesigns
Retrofitting power points or re-routing data cables after walls are plastered and ceilings are closed can cost 3–5x more than doing it correctly during the fit-out phase. Planning ahead eliminates this risk entirely.
Improves workflow efficiency
When power and data are exactly where your team needs them, work flows naturally. Staff aren’t running extension cords across the floor or huddling in the one spot where the WiFi is strong.
Supports your business operations and technology
Modern businesses rely on cloud systems, video conferencing, VoIP phones, dual monitors, and a constant stream of connected devices. Your infrastructure needs to support all of it — reliably.
Ensures safety and compliance
In Australia, electrical work must comply with AS/NZS 3000 (the Wiring Rules) and be performed by licensed electricians. Data cabling must meet AS/CA S008 standards. A proper plan ensures your fit-out passes inspection and keeps your team safe.
Key Components of a Power Plan
Power Point Layout
The positioning of power points is one of the most impactful decisions in an office fit-out. Poor placement leads to extension leads on the floor, overloaded boards, and safety hazards.
Workstations: Each workstation should have a minimum of 4–6 power outlets — enough for a computer, monitor(s), phone charger, desk lamp, and docking station. In open-plan offices, consider floor boxes or under-desk power modules to avoid trailing cables.
Meeting rooms: Boardrooms and meeting rooms require power at the table (for laptops and video conferencing equipment), at the wall (for screens and AV systems), and near the ceiling or behind panels for projectors. USB-A and USB-C integrated outlets are increasingly standard.
Breakout areas: Kitchen and breakout zones need dedicated circuits for appliances (see below), plus standard power points for casual laptop use.
Dedicated Circuits
High-draw equipment requires its own dedicated electrical circuits to prevent tripped breakers and interference with other systems:
- Server room / comms room: All server and network equipment must be on dedicated, protected circuits.
- Office equipment: Photocopiers, large format printers, and production equipment often require dedicated 15A or 20A circuits.
- Kitchen appliances: Ovens, microwaves, dishwashers, and coffee machines draw significant current and should never share circuits with office equipment.
Lighting Integration
Lighting is often treated as an afterthought — but it significantly impacts productivity, energy consumption, and occupant wellbeing.
- Task lighting provides focused illumination for individual workstations, reducing eye strain.
- Ambient lighting creates the general office environment and should be controllable by zone.
- Energy efficiency: LED fixtures, occupancy sensors, and daylight harvesting controls reduce energy bills and support sustainability goals. These must be planned into your electrical layout early.
Backup Power Solutions
Business continuity depends on what happens when the power goes out.
- UPS (Uninterruptible Power Supply) systems protect servers, network equipment, and critical workstations against sudden power loss, allowing clean shutdowns and preventing data loss.
- Generators: For larger offices or businesses with mission-critical operations, a diesel or natural gas generator may be required to maintain operations during extended outages.
Both UPS and generator connections must be incorporated into your switchboard and electrical design.
Key Components of a Data Plan
The data plan is often the most complex and consequential part of an office fit-out. It determines how fast, reliable, and future-ready your office network will be.
Data Point Placement
Every location where a device connects to the network via ethernet cable requires a data point (also called a network outlet or RJ45 port). Strategic placement is critical.
Desks and workstations: As a general rule, plan for a minimum of 2 data points per workstation — one for the computer and one as a spare for IP phones, docking stations, or future devices. In hot-desking environments, data points at every seat position ensures flexibility.
Meeting and conference rooms: Boardrooms should have at minimum 2–4 data points near the table, plus additional points for AV equipment, video conferencing systems, and wall-mounted displays. A meeting room with only WiFi is a meeting room that will eventually let you down.
Reception areas: Reception desks require data points for computers, EFTPOS terminals, and security/access control systems. Consider data points near the entrance for visitor management tablets or digital signage.
Network Cabling Infrastructure
The cables running behind your walls and above your ceilings form the backbone of your entire network. Choosing the right cable standard is a long-term decision.
Cat6 cabling is the current industry standard for most office environments. It supports speeds up to 10 Gbps over short distances and is sufficient for the majority of business applications, including VoIP, video conferencing, and cloud systems.
Cat6a cabling offers improved performance, supporting 10 Gbps over the full 100-metre run length with better interference rejection. It’s recommended for new fit-outs where future-proofing is a priority, particularly in environments with heavy device density or long cable runs.
Fibre optic cabling is used as a backbone between server rooms, floors, or buildings. It offers near-unlimited bandwidth and is immune to electrical interference — ideal for larger offices, multi-tenancy buildings, or data-intensive environments.

Server Room / Network Rack Setup
Even in a cloud-first business, you need a well-designed comms room or network rack to house the core equipment that runs your office network.
Patch panels terminate all the data cables from around the office in one organised location, making moves, additions, and changes straightforward.
Switches connect all your devices together and to the internet. The size and specification of your switches depends on the number of ports, required speed, and whether you need Power over Ethernet (PoE) for devices like IP phones and WiFi access points.
Cooling and ventilation are non-negotiable. Network equipment generates significant heat, and a rack operating in a poorly ventilated space will fail — often at the worst possible moment. Your comms room should have dedicated airflow, either passive or active, and temperature should be monitored.
Installation Old fittings are removed and new LED fittings are installed by licensed electricians. Any required wiring modifications, sensor installation, or switchboard work is completed at this stage.
WiFi Access Point Planning
Ethernet connections provide reliability, but WiFi is the day-to-day lifeline for most modern offices. Poor WiFi planning leads to dead spots, congestion, and dropped video calls.
Coverage zones: Access points (APs) should be positioned to provide overlapping coverage across all areas of the office, including meeting rooms, breakout areas, and corridors. A site survey during the planning stage uses signal mapping to identify optimal AP locations.
Eliminating dead spots: Concrete walls, lift shafts, and large metal structures are common sources of WiFi interference. Your data plan should account for these obstacles and position APs accordingly — often requiring more units than you’d initially expect.
PoE switches can power your APs directly through the data cabling, eliminating the need for separate power points at each access point location.
Aligning Your Plan with Office Layout and Workflow
The most technically sophisticated power and data plan will still fail if it doesn’t reflect how your team actually works. Your infrastructure should be designed around your people, not the other way around.
Desk layouts and team structure: Map data and power points to match your planned seating arrangement. If your sales team needs access to a shared printer, position the data point and power outlet in a logical central location. If your design team uses dual screens and multiple devices, plan for higher outlet density at those workstations.
Collaboration spaces: Open collaboration zones, project rooms, and casual meeting areas all need data and power — often more than planners anticipate. Think about how many people will use the space simultaneously and plan accordingly.
Flexibility for reconfiguration: Businesses change. Teams grow. Office layouts evolve. Building in additional data and power capacity now — extra outlets, spare cable runs in conduit, and modular floor boxes — makes future reconfiguration straightforward rather than expensive.
Scalability and Future-Proofing
One of the most valuable things you can do during an office fit-out is plan for a business that’s bigger than you are today. Infrastructure that can’t grow with you will cost you later.
Add extra data and power points beyond your current headcount. If you have 30 staff today, plan for 40 or 50. The marginal cost of a few extra data points during installation is minimal compared to the cost of retrofitting later.
Specify higher-grade cabling. Upgrading from Cat6 to Cat6a or installing a fibre backbone during the fit-out phase adds modest cost but extends the useful life of your infrastructure significantly — particularly important as device speeds and network demands continue to increase.
Plan capacity for additional devices. IoT devices, smart building systems, security cameras, digital signage, and environmental sensors all require network connections. Your switch ports and WiFi access points should have headroom for expansion.
Common Mistakes to Avoid
Even well-intentioned office fit-outs can go wrong. Here are the most frequent power and data planning mistakes — and how to avoid them:
Underestimating power and data needs
The most common error. Always plan for more capacity than you think you need. Devices, screens, and connected systems multiply quickly.
Poor cable management
Cables that aren’t properly routed, labelled, and managed become a nightmare to troubleshoot, expand, or modify. Invest in proper cable trays, conduit, patch panel labelling, and documentation from day one.
Ignoring future growth
Planning infrastructure only for your current headcount is a false economy. The cost of scalability built in from the start is far lower than retrofitting later.
Late planning in the project timeline
Power and data planning must happen before walls are built, floors are sealed, and ceilings are closed. Engaging your electrical and data contractor at the design stage — not after construction begins — is essential. Retrofitting even a single cable run after construction can cost hundreds of dollars; retrofitting a whole floor can cost tens of thousands.
Step-by-Step Planning Process
A structured approach ensures your power and data plan is comprehensive, accurate, and aligned with your fit-out timeline.
Step 1 — Requirement analysis:
Define your business needs. How many staff? What technology do they use? What are your future growth projections? What are your compliance requirements?
Step 2 — Site inspection:
A licensed electrical and data contractor inspects the space to assess existing infrastructure, building constraints (concrete walls, risers, existing conduit), and power capacity at the switchboard.
Step 3 — Layout design:
Based on your floor plan and requirements, your contractor produces a detailed power and data layout drawing showing the position of every outlet, data point, access point, and cable run.
Step 4 — Installation planning:
Sequencing is agreed with your builder or project manager to ensure cabling is installed at the right stage of the construction programme — typically before wall linings are installed.
Step 5 — Implementation and testing:
Cabling is installed, terminated, and tested to standard. Patch panels are labelled, switches are configured, and the system is documented for ongoing maintenance.
Cost Considerations
The cost of a power and data plan for an office fit-out varies widely based on several factors:
Office size is the primary driver — more floor area means more cable runs, more outlets, and more access points.
Number of workstations determines data point density and switch port requirements.
Type of cabling chosen — Cat6 vs Cat6a vs fibre — affects both material and labour costs. However, the premium for higher-grade cabling is typically 15–30% and is often the smartest investment you can make.
Building conditions affect installation complexity. Concrete structures, multi-storey buildings, and heritage premises all add cost compared to a standard single-floor commercial space.
The long-term ROI argument: A well-planned power and data infrastructure reduces IT support calls, eliminates productivity-killing downtime, avoids retrofitting costs, and extends the life of your infrastructure investment. Businesses that underinvest in this area routinely spend more money fixing problems than they would have spent doing it properly in the first place.

Future-ready infrastructure — scalable cabling and capacity headroom mean your office can grow, reconfigure, and adopt new technology without requiring a full infrastructure overhaul.
Frequently Asked Questions
How many data points does an office need?
As a general rule, plan for a minimum of 2 data points per workstation — one for the computer and one spare. Meeting rooms should have 2–4 points, and reception areas typically require 2–3. Always plan slightly above your current needs to accommodate growth and additional devices without costly retrofitting.
What type of cabling is best for offices?
Cat6 is the standard for most office environments, supporting up to 10 Gbps and covering typical office distances reliably. For new fit-outs, Cat6a is increasingly recommended as a future-proof upgrade. Larger offices or multi-floor buildings often benefit from a fibre optic backbone connecting floors or buildings, with Cat6/6a used for individual workstation connections.
How much does a power and data plan cost in Australia?
Costs vary depending on office size, number of workstations, cabling type, and building conditions. Small offices (under 10 staff) typically invest $3,000–$8,000, while mid-size offices (10–50 staff) commonly spend $8,000–$30,000. Larger or more complex fit-outs can exceed $100,000. Request a detailed quote from a licensed contractor for accurate pricing specific to your project.
Do I need licensed professionals for office power and data work?
Yes — in Australia, all electrical work must be carried out by a licensed electrician, and all data cabling connected to telecommunications infrastructure must comply with ACMA regulations and relevant Australian Standards. Unlicensed work is illegal, can void building insurance, and creates genuine safety risks. Always engage licensed, qualified professionals for your office fit-out.
Conclusion: Build the Foundation Right
Your office fit-out is an investment in your business. The furniture will be replaced, the fitout will evolve, and your team will grow — but the power and data infrastructure you install today will underpin all of it for the next 10 to 15 years.
A well-designed power and data plan is not an optional extra or a last-minute consideration. It is the foundation of a productive, connected, and future-ready workplace. Getting it right from the start saves money, prevents disruption, and gives your team the environment they need to do their best work.
