EV charging for strata buildings in Sydney

If your strata committee has received a request for an electric vehicle charger, start by looking at how charging could work across the building. Electrical capacity, shared costs and future access all matter, even when only one resident needs a charger today.

For apartment owners and strata managers across Sydney's Northern Beaches, a clear plan can make the decision easier. It gives residents a way forward and helps the owners corporation invest at a pace that suits the building. EV charging works best when it is planned at the building level from the start.

What EV ready means for your building

An EV-ready building has the supporting infrastructure and arrangements needed to connect chargers as demand grows. This may include electrical distribution boards, cable routes, communications, metering and load management.

This shared infrastructure is often called an EV backbone. Individual owners can then connect compatible chargers under an agreed process. The backbone can be installed in stages, with space and capacity reserved for future connections.

A smaller building with limited demand may suit an approved individual installation or a simpler interim solution. The plan should explain how later residents could gain access too.

Check electrical capacity before choosing chargers

A building assessment should establish what the existing supply can support and where upgrades may be needed. Ask your electrical contractor to review:

• The incoming supply, switchboards and existing electrical loads.

• Peak demand and the needs of lifts, pumps and other shared services.

• Cable routes, parking layouts and car park communications.

• Likely charging demand and planned solar, battery or other electrical upgrades.

Dynamic load management can adjust compatible chargers as the building's electricity demand changes. When other services need more power, charging can slow down; when capacity becomes available, it can increase.

This can help a building use its existing supply more effectively and may avoid or defer some upgrades. The assessment must establish whether it will meet residents' charging needs.

Match charging speed to everyday use

The right charging speed depends on daily driving, how long cars remain parked and how many vehicles need to charge together. A managed power outlet may suit some buildings; dedicated AC chargers may suit others.

An existing car park socket should be assessed before it is used for regular EV charging. Its circuit, protection, metering and approval arrangements all need to be suitable.

Make the costs clear

Separate the shared infrastructure cost from the cost of connecting each charger and the ongoing cost of using it. A proposal should explain:

• Who funds the common infrastructure and how future connections contribute.

• Who pays for individual chargers and their installation.

• How each user pays for electricity and any service fees.

• Who pays for maintenance, repairs and replacement equipment.

The owners corporation should agree on the allocation through the appropriate NSW approval process. Metering and billing should make electricity use transparent, with clear reporting and a workable process for collecting payments.

Compare the full cost over several years, including software subscriptions, billing fees and maintenance. A lower installation price can come with higher ongoing charges.

Understand NSW strata approvals

NSW has a sustainability infrastructure resolution pathway for works such as EV charging. The required approvals and by-laws depend on the proposal, including how it affects common property and who will own and maintain the equipment.

Have your strata manager or strata solicitor confirm the motions, voting requirements and by-laws before the proposal goes to a meeting. Owners should seek approval before installing charging equipment; tenants should begin with their landlord or managing agent.

Include insurance and relevant fire safety arrangements in the planning. Your electrical contractor, insurer and relevant building specialists can identify what the design, emergency information and maintenance arrangements need to cover.

Check compatibility and ongoing support

Ask whether the proposed chargers can work with the building's load management and billing systems, and what happens if the service provider changes.

Open Charge Point Protocol, or OCPP, can help compatible chargers communicate with management platforms. The installer should verify the actual functions and compatibility; an OCPP label alone does not guarantee that every product will work together.

Check who owns the equipment and usage data, how faults are handled, what happens during a communications outage and what it costs to leave the service contract.

Give owners a practical proposal to consider

Explain the options, likely costs and responsibilities before asking owners to support a proposal. Gather information about current and expected charging needs, and give people without an EV a clear explanation of what they would fund.

A staged project may be suitable: establish the design and approvals, install the shared infrastructure needed now, then add chargers as residents request them. If installation is premature, document what would trigger a review.

Discuss your strata building with Energy Culture

Energy Culture is based on Sydney's Northern Beaches. We work across electrical services, solar, batteries and EV charging for homes and businesses in the area. We value clear advice, quality workmanship and being available when customers need support.

If your building is considering EV charging, contact us to discuss the electrical requirements and the next step. Bring your building address, approximate number of parking spaces and any requests already received from residents.
