The short answer

NG Elec is a licensed commercial electrical contractor (PGE285103) based in Hackham. We do fault finding, repairs, LED lighting, new circuits, switchboard upgrades, fit-outs and commercial solar and batteries for businesses and property managers across South Australia. Every job gets a written scope and a free itemised quote, and work is staged around your trading hours.

Is this you?

Common reasons businesses call us

Nuisance tripping

Circuits dropping out during the day cost you trade. We test, reproduce the fault where we can and fix the cause.

New equipment or a fit-out

New machines, kitchens or a tenancy change often need extra circuits. We check supply and switchboard capacity first.

Old, costly lighting

Tired fluoro and halogen lighting can be swapped for LED with sensors where they make sense.

Power bills climbing

Daytime-heavy businesses are often a good fit for commercial solar and batteries. We can assess it while we're on site.

What we do

Commercial electrical services

From one tenancy to multiple sites, with licensed electricians and written scopes.

Fault finding and repairs

Intermittent faults, tripping, dead circuits and damaged fittings, tested and fixed.

Lighting

LED changeovers, emergency lighting checks, sensors, car park and security lighting.

Power and circuits

New power points, dedicated circuits for equipment, rewiring and layout changes.

Switchboard and supply upgrades

Board replacements, safety switches and three-phase upgrades when equipment outgrows the supply.

EV chargers for staff and fleets

Workplace chargers with load management so they don't push your site over its supply limit.

Commercial solar and batteries

Designed around your daytime load. See our Kangarilla General Store project.

How it works

How we work on an active site

  1. Site visit and scope

    We look at the job, confirm access and identify which circuits will be affected.

  2. Written quote

    A free, itemised quote with the scope in writing, so you can sign it off internally.

  3. Planned shutdowns

    We agree isolation times with you in advance and stage the work so parts of the site stay running.

  4. Test and hand over

    Everything's tested, documented and certified where required, and installs are covered by our lifetime workmanship warranty.

Pricing

What affects the price

Commercial jobs vary a lot, so every quote is itemised and free. The main things that move the price:

  • Site access, heights and working around staff or customers
  • How complex the fault or scope is
  • Switchboard and supply capacity
  • Equipment and fittings specified
  • Staging the work to keep you trading

Real work

Case study · Kangarilla, SACommercial solar and battery backup for Kangarilla General Store

We installed 27.5 kW of solar and a 96 kWh Sigenergy battery with backup at Kangarilla General Store. The store was paying about $18,000 a year for power and wanted to cut that and keep trading through blackouts.

FAQ

Questions people ask us.

Do you handle both repairs and bigger upgrades?

Yes. We do everything from a single faulty circuit to switchboard upgrades, fit-outs and commercial solar. Larger jobs are staged around your site access.

What hours do you work?

Monday to Friday, 8am to 5pm. We don't run an emergency service, so we're best suited to planned work, repairs and ongoing maintenance.

Do you work with property managers?

Yes. We look after landlords, property managers and multi-site businesses. See property maintenance electrician for how that works.

How much does a commercial electrician cost?

It depends on access, the fault or scope, parts and how the work needs to be staged. We give you a free, itemised quote before we start.

Is your work guaranteed?

Yes. Our installs carry a lifetime workmanship warranty, and we're licensed (PGE285103) with $20M public liability.

Can you work around our trading hours?

Yes, within Monday to Friday, 8am to 5pm. We agree isolation times with you in advance and stage the work so parts of the site keep running.

Can you work outside Adelaide?

Yes. We cover all of South Australia, including the Hills, the Fleurieu, the South East, Kangaroo Island and the Yorke and Eyre Peninsulas.
