Who's responsible — you or the landlord?
Commercial leases generally split electrical responsibility somewhere between these two.
The number that dwarfs the quote
Downtime is the real cost
Most commercial electrical quotes are compared on labour and materials. The number that usually dwarfs both is the hours you can't trade.
- We plan around it rather than through it. Before work starts, we identify exactly which circuits and areas are affected and for how long.
- Shutdowns go in your lowest-impact window — after close, before open, overnight, or over a weekend.
- Materials are staged in advance, so the outage window covers the work and not the preparation.
- We isolate rather than blanket-shut wherever the distribution allows it, keeping the rest of the premises live.
- Critical loads get planned around specifically. Refrigeration, freezers, servers, security, and anything with a temperature or data consequence is identified up front, including temporary supply where appropriate.
And we tell you honestly when something can't be done live. Some work requires the power off. Knowing that during planning is far more useful than discovering it mid-shift.
If you've only dealt with residential electricians
What three-phase changes
Most commercial premises take three-phase supply rather than the single-phase service a house gets. It delivers more power more efficiently, and it's what allows large motors — compressors, lifts, HVAC, machinery — to run properly.
- Motor and equipment loads behave differently from lighting and receptacle loads, particularly at start-up, when they draw far more than their running current.
- Load balance across phases matters. An unbalanced system runs hot, wastes energy, and stresses equipment. It's one of the things worth checking during any significant work.
- Panels and distribution are more complex — multiple panels, subpanels, and often a mix of voltages within one building for lighting versus equipment.
- Fault-finding takes longer, because circuits rarely map neatly to rooms and documentation is frequently missing or out of date.
Electricians who work mainly in homes aren't necessarily equipped for this. It's a reasonable thing to ask about before hiring anyone.
Found during inspections and insurance reviews
Compliance obligations you may not know you have
Requirements vary by jurisdiction and building type, so treat this as a prompt to check rather than a definitive list.
We'll tell you what applies to your property and what the records should look like.

We work around your hours
Evening, overnight, and weekend scheduling where daytime work would cost you more in lost trade than the premium costs in labour.
We document properly
Permits, inspection sign-offs, test records, and updated panel schedules. Commercial paperwork gets asked for — by inspectors, insurers, landlords, and buyers.
One contractor across the property
The same team that knows where your panels are, what's on them, and what was done last time.
Licensed, insured, background-checked
Certificates of insurance provided where your landlord or management company requires them before work begins.

Prevention
Planned maintenance beats reactive repair
Most commercial electrical failures give warning. Connections loosen and heat gradually. Breakers weaken before they stop holding. Load creeps upward as equipment is added over years without anyone recalculating.
A maintenance visit typically covers panel and connection inspection, thermal checks for hot spots, load balance across phases, breaker condition, grounding verification, testing of emergency systems and GFCI protection, and a review of what's changed since last time.
Why it pays: a fault found during a scheduled visit costs a service call. The same fault found at 7pm on a Friday costs a service call at premium rates plus whatever the closure cost. For food premises, add spoiled stock.
For multi-site operators, scheduled maintenance also produces consistent records across the portfolio, which makes capital planning and budgeting considerably easier — and satisfies insurers who ask.
New premises and turnovers
Fit-outs and tenant improvements
New premises, a change of use, or a tenant turnover all mean electrical work, and the sequencing matters more than most people expect.
We work from drawings or design to requirements, coordinating with the general contractor and other trades so the electrical rough-in doesn't become the thing holding up the schedule.
Worth deciding early: equipment locations and their power requirements, lighting layout and controls, data and low-voltage routing, and whether the existing panel and service support the intended use. Discovering a capacity shortfall after the layout is finalised is expensive.
Landlord approvals and base building coordination are frequently part of the process, along with permits and inspection.
For departing tenants, make-good obligations sometimes include electrical reinstatement. Worth checking the lease before assuming.
Efficiency
Lighting and energy
Lighting is often the largest controllable electrical load in a commercial building, and the economics are usually better than people assume.
- The energy saving is only part of it. LED replacements last considerably longer, which matters most where fixtures are difficult to reach — warehouse high-bays, exterior poles, high ceilings. The labour and equipment cost of relamping frequently exceeds the energy saving on its own.
- Controls extend the benefit. Occupancy sensors in storage, washrooms, and back-of-house, daylight sensors near glazing, and scheduling for exterior lighting reduce running hours without anyone thinking about it.
- Light quality affects trade. Colour temperature and rendering change how product looks in retail and how food looks in a restaurant. Cheap fixtures with poor colour rendering can cost you more in presentation than they save in energy.
- Incentives. Many utilities and regional programs offer commercial lighting incentives. Availability and terms change, so check what currently applies before scoping a project — it can shift the payback meaningfully.
How it works
Our process

Site assessment
The system, the loads, the critical equipment, your trading pattern, and any compliance obligations.
-
Scope and written quote
Defined scope, price, and — importantly — the outage window and how it will be scheduled.
-
Permits and coordination
Permits pulled, landlord and building management notified where required, and other trades coordinated.
-
Execution
Work carried out in the agreed windows, with areas isolated rather than blanket-shut wherever possible.
-
Testing and documentation
Testing, inspection sign-off, updated panel schedules, and records for your compliance file.
Pricing
What affects the cost
- Scope and scale — a service call, a lighting retrofit, and a full fit-out differ by orders of magnitude.
- Service and panel capacity — whether existing equipment supports the work.
- Building construction and age — concrete, steel deck, and finished ceilings versus open framing.
- Occupied or vacant — working around trading is slower than an empty space.
- Out-of-hours scheduling — premium labour rates, usually offset by avoided closure.
- Documentation requirements — where testing and reporting are part of the deliverable.
- Coordination with other trades — on fit-outs, sequencing affects total duration.
- Permits and inspection — variable by jurisdiction and project type.
You'll get a written scope and price before work begins.

Questions
Frequently asked questions
Am I responsible for this repair, or is my landlord?
It depends where the fault sits and what your lease says. Base building systems are typically the landlord's; everything inside the demised premises is typically the tenant's. We can tell you which side of the line the fault is on.
How do you limit downtime?
By identifying affected circuits in advance, isolating rather than blanket-shutting, staging materials before the window opens, and scheduling around your trading hours.
Can you work outside business hours?
Yes, including evenings, overnight, and weekends where daytime work would cost more in lost trade than the labour premium.
Do you work with all commercial property types?
Yes — restaurants, retail, offices, warehousing, light industrial, healthcare, fitness, and multi-tenant residential buildings.
What's the difference between commercial and residential electrical work?
Three-phase supply, larger distribution, equipment-driven loads, compliance obligations, and documentation requirements. It's a different skill set, and it's fair to ask any contractor about their commercial experience.
Do you provide certificates of insurance?
Yes. If your landlord or property manager requires documentation before work begins, we'll supply it.
Do I need a permit for commercial electrical work?
Most work involving new circuits, panels, service changes, or fit-outs does. We handle permitting and coordinate inspection.
Do you handle emergency and exit lighting testing?
Yes, including installation, periodic testing, and the record-keeping that inspections require.
Can you help with a fit-out schedule?
Yes — we work from drawings or to requirements and coordinate with the general contractor and other trades. Involving us early usually prevents capacity surprises after the layout is fixed.
Do you offer planned maintenance contracts?
Yes, including scheduled inspections, thermal checks, testing, and documentation — across single sites or portfolios.
Our energy costs are rising with no change in operations. Can you help?
Often. Aging lighting, equipment drawing more than it should, systems running longer than necessary, and unbalanced loads are all common causes and all identifiable.
Can you add capacity for new equipment?
Yes. We assess existing service and distribution against the new load, then upgrade panels, add subpanels, or increase service as required.
Do you work with property management companies?
Yes, across multiple sites with a single point of contact and consistent documentation for each property.
Systems, stakes, and who pays
Commercial electrical work asks three questions a residential job never does: what does this building actually run, what does an hour of downtime cost, and whose responsibility is this under the lease.
Summit Electrical Services works through all three before quoting — and schedules the work around your trading rather than around ours.
