Complete Electrical Installation for a New JB Hi-Fi Retail Build

Delivering electrical infrastructure for large-format retail environments requires precision, coordination, and the ability to work to strict commercial deadlines. Our team recently completed a full electrical installation for a new JB Hi-Fi retail store, providing a complete end-to-end solution from initial rough-in through to final commissioning and handover.

The Project

The project involved the full electrical fit-out of a new JB Hi-Fi retail tenancy within a high-traffic commercial development. The store required a modern, high-capacity electrical system capable of supporting:

• Large-scale retail lighting
• High-demand power distribution
• Audio visual display systems
• Data and communications infrastructure
• Security and CCTV systems
• Emergency and exit lighting
• HVAC electrical services
• Point-of-sale systems
• Back-of-house operations

Given the scale of the store and the fast-paced construction programme, efficient coordination with builders, shopfitters, HVAC contractors, and data teams was critical throughout the project.

Planning & Coordination

Retail construction projects operate on tight timelines, making detailed planning essential from day one.

Working closely with the project manager and other trades, we developed an installation programme that ensured all electrical works aligned with key construction milestones and store opening deadlines.

This included:

• Main distribution planning
• Lighting layouts and switching design
• Power allocation for retail displays
• Data and communications pathways
• Emergency compliance systems
• Future maintenance accessibility

Our focus was to deliver a reliable and scalable installation while maintaining clean finishes throughout the tenancy.

First Fix Electrical Works

During the first fix stage, our electricians completed the core infrastructure installation across the site.

Works included:

• Cable tray and containment systems
• Main switchboard installation
• Submain cabling
• Power and lighting circuits
• Data and communications rough-in
• Security and access control prewiring
• Emergency lighting infrastructure

Retail environments like JB Hi-Fi require significant coordination due to the volume of technology, display systems, and specialised equipment installed throughout the store.

Retail Lighting Installation

Lighting plays a major role in creating the customer experience within large retail environments.

For this project, we installed a high-efficiency commercial LED lighting system designed to provide:

• Bright, even illumination across retail floors
• Feature lighting for promotional areas
• Energy efficiency and long-term performance
• Reduced maintenance requirements

The lighting layout was carefully coordinated with shelving, signage, and display areas to ensure maximum visibility throughout the store.

Power & Technology Infrastructure

Modern electronics retailers require substantial power and data capacity to support operational demands.

Our installation included:

• Dedicated circuits for display systems
• POS and checkout power supplies
• Data cabling infrastructure
• AV display connectivity
• Back-of-house power distribution
• Staff amenities and office services

Special consideration was given to equipment reliability, cable management, and accessibility for future upgrades.

Testing, Compliance & Handover

As the project moved into final fit-off, our team completed all testing, commissioning, and compliance procedures to ensure the store was ready for operation.

This included:

• Full electrical testing and certification
• Emergency lighting testing
• Switchboard commissioning
• Fault loop and RCD testing
• Final lighting adjustments
• Client walkthrough 

All works were completed within programme deadlines, allowing the store to proceed smoothly toward opening.
