A strata switchboard upgrade affects more than the electrical room. If the work interrupts power to apartments, lifts, garage doors or shared lighting, residents need time to prepare and the building manager needs a clear plan for access and restoration.
For strata managers and owners corporations in Sydney, the key is to coordinate the electrical assessment, approvals, contractor access and resident notices before an outage is booked. The exact arrangements depend on the building’s electrical layout and the work required.
This guide explains what to organise, what to ask the electrician and how to keep residents informed from the initial inspection through to the final handover.
What Does a Strata Switchboard Upgrade Involve?
A strata switchboard upgrade can involve repairing or replacing a main switchboard, upgrading protective devices, modifying circuits or making changes to support additional electrical demand. It does not necessarily mean replacing every switchboard in the building.
A building may have a main distribution board, separate apartment boards, metering equipment and switchboards for common-property services. Before planning the work, an electrician should determine which parts of the installation need attention and which occupants or building systems could be affected.
The practical sequence is to assess the switchboard, confirm the scope and approvals, plan access and outages, notify residents, complete the work and testing, then collect the relevant compliance documentation.
When Should a Strata Building Consider a Switchboard Upgrade?
An old switchboard is not automatically unsafe because of its age. Its condition, protection devices, capacity and compliance need to be assessed by a licensed electrician.
An inspection is particularly useful when the building has:
- Recurring electrical faults, unexplained outages or breakers that frequently trip.
- Visible damage, deterioration, signs of overheating or obsolete equipment.
- Insufficient capacity for planned works, such as new mechanical services or EV charging.
- A defect notice or inspection finding that identifies an electrical safety concern.
- Renovation or building projects that may affect metering, supply connections or main distribution equipment.
The right solution might be targeted repairs, new protection devices, alterations or full replacement. Ask for the cause of the problem and the reason for the recommended scope, rather than assuming the largest job is necessary.
Confirm Responsibility, Quotes and Approvals First
In NSW, an owners corporation is generally responsible for maintaining and repairing common property. Whether particular switchboards or cables are common property depends on the strata plan, boundaries and relevant by-laws. Strata managers should confirm ownership before allocating costs or arranging access to individual lots.
The NSW Government advises that all schemes must obtain at least two independent quotes for non-emergency work valued at $30,000 or more. Emergency repair exemptions may apply. Repairs, alterations and improvements can also have different approval requirements, so confirm what decisions need to be made by the committee or owners corporation.
The NSW Government’s strata repairs and maintenance guidance explains the common-property process, while its strata building repairs health check recommends confirming the necessary approvals before work starts.
What to request in a switchboard upgrade quote
A useful quote should do more than list equipment. Ask the contractor to identify:
- The switchboards and components included in the work.
- Whether the quote is for repairs, replacement, capacity changes or a combination.
- Which apartment and common-property circuits may need isolation.
- Estimated work and outage windows, including key dependencies.
- Access requirements, testing, certification and any exclusions.
- Whether other specialists, metering providers or network coordination may be required.
Clear inclusions make it easier to compare quotations and explain the proposed work to the strata committee.
Arrange Access Before Booking the Electrician
A locked switch room, inaccessible meter cupboard or blocked basement work area can hold up an otherwise straightforward project. Ask the electrician to inspect the site and agree on the required access before the installation date.
Electrical rooms and common areas
Identify who holds keys, access cards or building-management permissions. Confirm whether the contractor needs access to roof spaces, basement switchboards, meter rooms or garages, and arrange for stored items or vehicles to be moved where necessary.
Individual lots and resident appointments
Some jobs can be completed from common areas; others may require access to particular apartments to inspect, isolate or test circuits. If lot access is needed, identify the affected residents early and follow the building’s applicable access and notice requirements.
Other building contractors
A planned isolation may affect lifts, pumps, ventilation, security, garage doors or fire safety equipment. Where relevant, coordinate with the people responsible for those systems. Do not assume that all services will continue operating during the outage.
Plan the Power Outage Around the Building
Most substantial switchboard work requires the affected circuits or supply to be safely isolated. The outage may involve a single common-property board, a group of apartments or a wider building supply, depending on the electrical design.
Map what will lose power
Ask the electrician to identify the affected circuits and the expected impact on:
- Individual apartment electricity supplies and metering.
- Corridor, stairwell and external lighting.
- Lifts, access controls and powered garage doors.
- Water pumps, mechanical ventilation and other essential building equipment.
- Fire safety systems or any equipment requiring specialist coordination.
This list is a starting point, not a substitute for a site-specific assessment. A competent contractor should confirm what can remain energised and what cannot.
Agree on realistic timing and contingencies
Outage duration depends on the switchboard condition, the scope of wiring changes, testing and any disconnection or reconnection arrangements. A standard estimate should not be presented as a guaranteed restoration time.
Ask how unexpected defects will be communicated, who can authorise additional work and who will update residents if the outage runs longer than planned. For related background, IZCO Electrical explains what happens to your electricity supply during a switchboard upgrade.
Check residents who depend on electricity
Allow affected residents to raise important access or support needs in advance, including reliance on powered medical equipment. They may need to contact their electricity retailer, equipment provider or healthcare team to plan for a temporary interruption. The strata manager and contractor should also address any specific building safety contingencies.
How to Write an Effective Resident Outage Notice
A vague notice that says ‘electrical work will be carried out’ is unlikely to answer residents’ main questions. Communication should state the likely impact, explain what people need to do and provide a reliable contact.
Include the following in the initial notice:
- Why the electrical work is being arranged.
- The proposed date and estimated start and finish times.
- Which apartments, entrances, common facilities or services may be affected.
- Whether residents need to provide access, move vehicles or prepare for a garage-door interruption.
- Practical preparation advice, such as saving work and planning for equipment that needs power.
- The strata contact for enquiries and how residents will receive changes or completion updates.
Sample resident notification
Notice of planned electricity interruption: Switchboard work is scheduled for [date] between approximately [start time] and [end time]. Power to [affected apartments/areas] may be unavailable during this period. Please [specific preparation or access instruction]. Times are estimates and we will provide an update if the schedule changes. For enquiries, contact [strata contact details].
Use the actual outage scope and contractor-approved timing before sending this notice. Email, building noticeboards and resident communication platforms can help reach both owners and tenants. A reminder closer to the work date may reduce missed access appointments.
What Happens on the Day of the Upgrade?
A planned strata switchboard project will usually involve these stages, with the order and responsibilities adapted to the site.
1. Confirm access and the isolation plan
The contractor checks the work area, confirms any affected services and verifies that the necessary safety and access arrangements are in place.
2. Isolate and make safe
Appropriately qualified personnel isolate the relevant supply and confirm it is safe for the electrical work. Where the work involves certain service or network connection activities, an accredited Level 2 electrician may be required.
3. Complete the agreed electrical work
The electrician carries out the approved repairs, replacement, installation or alterations. If an unexpected condition changes the scope, the building’s authorised representative should be informed before additional work is approved.
4. Test and restore supply
The electrician performs the required inspections and tests before the installation is returned to service. Any restoration or network coordination requirements should be completed in the agreed manner.
5. Confirm the handover
The nominated representative should receive an explanation of the completed work, any outstanding recommendations and the relevant compliance documents. Residents should be told when the planned outage has ended.
Electrical Compliance and Records in NSW
Switchboard alterations must comply with applicable NSW electrical safety rules and relevant Australian Standards, including the AS/NZS 3000 Wiring Rules where applicable. Electrical wiring work must be carried out by, or under the supervision of, a licensed electrician.
For electrical work requiring a Certificate of Compliance for Electrical Work (CCEW), NSW requires the certificate to be submitted through BCNSW eCert. This online submission process became mandatory on 1 July 2026; the NSW electrical advisory guidance says the certificate must be lodged within seven days of the completed test.
Strata managers should ask for the relevant CCEW copy and retain it with the approved quote, invoices, inspection findings and other building records. See the NSW Government’s electrical compliance requirements for current submission and documentation guidance.
Strata Switchboard Upgrade Checklist
Before the work starts, confirm that the following items are covered:
- A licensed electrician has assessed the switchboard and proposed scope.
- The owners corporation has confirmed responsibility, budget and necessary approvals.
- Written quotes, exclusions and required specialist roles are understood.
- Electrical-room access and any apartment appointments are arranged.
- The contractor has identified affected circuits and building services.
- Outage timing, contingency contacts and resident communications are agreed.
- Residents have received clear notice and preparation instructions.
- Testing, power restoration and handover responsibilities are confirmed.
- Compliance documentation will be collected and filed after completion.
This checklist will not replace a site assessment, but it can help prevent avoidable delays and communication problems.
Frequently Asked Questions
Who pays for a strata switchboard upgrade in NSW?
The owners corporation generally funds work to common-property infrastructure. Responsibility for equipment within a lot depends on the strata plan, property boundaries and relevant by-laws. Confirm the classification before approving the expense.
Does every apartment need to lose power?
No. Some work may be isolated to particular boards or shared areas, while other jobs require wider shutdowns. Only a site-specific electrical assessment can establish the likely impact.
How much notice should residents receive?
Give residents sufficient advance information to make practical arrangements and comply with any applicable strata or network notice requirements. The appropriate timing depends on the scope, affected services and access obligations.
Will a strata switchboard upgrade require a Level 2 electrician?
Not always. Ordinary switchboard work may be carried out by a suitably licensed electrician, but particular supply connection, disconnection or service equipment work may require appropriately accredited Level 2 personnel.
How long will the power be off?
There is no reliable fixed duration for every building. The contractor should estimate the interruption after inspecting the existing installation and identifying testing and network dependencies.
