EV Charging Infrastructure for New Melbourne Developments: A Guide for Builders and Developers

Retrofitting EV charging into a completed building is expensive and disruptive. Planning it in during the design and construction phase of a new development is a fraction of the cost, and it's becoming a genuine differentiator for developments trying to attract buyers and tenants who already own or plan to own an EV. EAY Electrical works with builders and developers across Melbourne to plan EV infrastructure into new residential and mixed-use developments from the ground up.

Why Planning Ahead Changes the Economics Entirely

Running conduit and cable trays to every car space during construction, before walls, ceilings, and finishes are in place, is dramatically cheaper than cutting into finished surfaces later. It also means the electrical design — switchboard capacity, supply sizing, load management — is planned around the full building's future EV demand from day one, rather than being constrained by whatever capacity happens to be left over after the fact.

What Developers Should Be Planning For

• Supply capacity for full build-out: Even if only a portion of car spaces get chargers installed at handover, the incoming electrical supply should be sized for eventual full EV adoption across the development, not just current demand.
• Conduit and cable tray routes to every space: Running the physical infrastructure to every car space during construction, even if chargers aren't installed until later, avoids costly retrofit work entirely.
• Smart load management systems: For developments with dozens or hundreds of car spaces, a smart charging system that dynamically distributes available power is what makes large-scale EV charging feasible without an oversized, expensive supply upgrade.
• Sub-metering for individual billing: In multi-unit developments, sub-metered chargers allow individual owners or tenants to be billed for their own usage, which matters significantly for body corporate structures down the line.

Why This Matters for Buyer and Tenant Appeal

EV charging capability is increasingly a genuine factor in purchase and lease decisions, particularly in developments targeting buyers who already drive an EV or are planning to. A development marketed with "EV-ready" car spaces — meaning the infrastructure is already in place, even if chargers are added progressively — has a real point of differentiation over a comparable development that offers no EV provision at all.

Working With Your Electrical Design From the Start

EAY Electrical works directly with developers, builders, and design teams during the planning stage — not after construction is underway — to make sure EV infrastructure is properly sized into the electrical design from the outset. This includes providing documentation suitable for planning approvals and coordination with the broader electrical design of the development.

Frequently Asked Questions

When should EV infrastructure be planned into a development?

As early as possible — ideally during the electrical design phase, before construction begins, since retrofitting after completion is significantly more expensive.

Do all car spaces need chargers installed at handover?

Not necessarily. Many developments run conduit and size supply capacity for full build-out, then install chargers progressively as demand grows.

How does billing work for EV charging in a multi-unit development?

Sub-metered charger installations allow individual owners or tenants to be billed for their own usage, which is the standard approach for multi-unit developments.

Can EAY Electrical work directly with our design team?

Yes. We work with developers, builders, and design teams during the planning stage to size EV infrastructure into the overall electrical design.
