A commercial electrical fit-out is the design, installation, testing, and certification of every electrical system in a business premises before it opens for trade. In Melbourne, the process moves through five stages and typically takes 2 to 6 weeks depending on the size of the tenancy and the complexity of the equipment being installed.
Every fit-out must comply with AS/NZS 3000 (the Wiring Rules), the National Construction Code, and Victorian Energy Safe Victoria (ESV) regulations. On completion, the building owner receives a Certificate of Electrical Safety (COES) for the new installation.
This guide covers each stage in detail, what to expect at every step, who is responsible for compliance, and what documentation you should receive when the work is signed off.

Step 1 Initial Consultation and Planning
The process starts with understanding your operational needs and business layout. This phase involves:
- Site inspection and assessment
- Reviewing architectural or tenancy plans
- Discussing power, lighting, data, and equipment requirements
- Identifying high-load equipment or specialised systems (e.g. HVAC, server racks)
- Planning for future scalability and energy efficiency
A detailed scope of works is developed to outline the installation and ensure alignment with your goals and budget.
Step 2 Design and Compliance
Before installation begins, our commercial electricians prepare a full electrical layout and ensure it complies with:
- AS/NZS 3000 (Wiring Rules)
- The National Construction Code (NCC)
- Workplace health and safety regulations
- Specific landlord or building requirements
All designs are future-focused to allow for modifications and additional load where required.
Step 3 Installation of Electrical Systems
With planning complete, installation begins. Depending on your project size and type, this may include:
- Power distribution and circuit setup
- Lighting systems (general, feature, and emergency)
- Data and communications cabling
- Switchboards, submains, and load balancing
- Security systems, alarms, and CCTV
- Dedicated circuits for machinery or commercial appliances
Work is carried out efficiently and safely to minimise disruption to other trades or fit-out timelines.
Step 4 Testing and Certification
Once the installation is complete, thorough testing is conducted to ensure:
- All systems operate correctly and safely
- Emergency and safety lighting is compliant
- RCDs and switchboards perform as required under load
- There are no faults, overloads, or safety hazards
You’ll be provided with relevant compliance documentation, including a Certificate of Electrical Safety (COES).
Step 5 Handover and Ongoing Support
The final stage includes a walk-through of the new systems, guidance on usage, and future maintenance tips. For many clients, we continue to provide:
- Scheduled servicing and maintenance
- Emergency repairs and troubleshooting
- Energy efficiency reviews and upgrade planning
How Much Does a Commercial Electrical Fit-Out Cost in Melbourne?
The cost of a commercial electrical fit-out in Melbourne depends on the size of the tenancy, the complexity of the systems, and the existing electrical infrastructure. As a rough guide for 2026:
- Small office or retail (under 100 m²): typically $8,000 to $25,000
- Mid-size commercial (100 to 300 m²): typically $25,000 to $75,000
- Large commercial or hospitality (300 m² plus): typically $75,000 upward
- Industrial fit-outs with three-phase machinery, dedicated circuits, or data centre work: quoted on scope
Costs are driven by switchboard capacity, total circuit count, lighting design, data cabling, emergency lighting, and the level of automation or building management integration.
