Power Infrastructure and Upgrades

Lifetime Workmanship Guarantee

We stand behind our work with a lifetime workmanship guarantee. If any issues arise from our installations or repairs, we'll make it right at no additional cost.

Clean, safe, and practical power solutions, with every detail considered.

Power that’s built for performance and installed with precision. Northman Electrical delivers commercial power systems that support day-to-day operations without compromise.


We work across Perth’s business sectors, from commercial kitchens and transportable homes to warehouses, retail spaces, and shared facilities, installing power infrastructure that’s designed for safety, compliance, and long term reliability. Whether it’s single-phase, three-phase, or a full power upgrade, every outlet and circuit is planned with your operations in mind.

The power needs of commercial spaces are as varied as they are vital. We understand this as we work with various businesses, from high-demand catering venues to modern transportable homes.


We specialise in:

  • Single and three-phase outlet installations.
  • Power upgrades for kitchens, warehouses, cafés, and carparks.
  • Distribution boards and circuit planning.
  • Power relocations and alterations.

We’re well connected within the industry and can source obsolete components to keep older switchboards operational and compliant.

If you run a commercial kitchen or an industrial shed, a three-phase power system might suit your needs the best. It allows for more efficient and stable delivery of electricity in such high load environments. Our team knows how to set it up for optimal performance, and how to prepare your system for future growth.


Power distribution is never just about plugging things in. It’s about ensuring balanced loads, compliance with AS/NZS standards, and a finish that blends into the environment. We mount outlets at heights that work for your staff, and ensure waterproofing or load protection where needed.


From a single café to a multi-unit development, we focus on details and we work with you or your site manager to minimise disruption during the install.

Need more power? We’ll make it happen.
For both new fitouts or critical upgrades, we’ll design a safe, compliant system that supports your business.
