Lithium-Ion and Australian Property: What Buyers, Sellers and Agents Should Know in 2026
A decade ago, buying a house didn't require thinking about lithium-ion batteries. In 2026 it does — and it's changing what gets disclosed, what's worth inspecting, what affects asset value, and what an agent needs to know to do their job properly.
Solar batteries are now in roughly 1 in 24 Australian homes after the federal Cheaper Home Batteries Program kicked off in July 2025, and the number is climbing fast. Over 117,000 EVs are registered in NSW alone, meaning a growing percentage of garages now have hardwired wallboxes. E-bikes, e-scooters, mobility scooters, drones and cordless tools sit in nearly every property the agent walks through. And almost every strata building now has at least one lithium-ion question hanging over it.
This post is for buyers, sellers, real estate agents, conveyancers, building inspectors, and anyone else involved in property transactions — what to ask, what to look for, and what affects value.

What's now on the property risk checklist
1. Home battery (BESS) installation
If the property has a wall-mounted or floor-standing home battery, the relevant questions:
- What model and what capacity?
- When was it installed?
- Was it installed by a Solar Accreditation Australia (SAA) accredited installer?
- Does it comply with AS/NZS 5139?
- Is the battery on the Clean Energy Council (CEC) approved product list?
- Is there written compliance documentation?
- Was the federal Cheaper Home Batteries rebate claimed (and therefore is the install verified)?
- What's the warranty period and remaining life?
- Are inspection records available?
2. EV charger
- What's the charger make and model?
- Was it professionally installed under AS/NZS 3000?
- Is there a Certificate of Electrical Safety?
- Was the switchboard upgraded?
- Is the charger OCPP-compatible (smart-grid-ready, increasingly mandatory)?
- Single-phase or three-phase install?
3. Modifications, additions and the unauthorised stuff
The risky scenario is the install that wasn't done properly:
- Owner-installed wallbox without electrician
- Aftermarket home battery added later, not compliant with AS/NZS 5139
- Caravan battery setup that doesn't meet AS/NZS 3001.2:2022
- Solar panels added without inverter upgrade
- Garage modifications that compromise fire separation
These aren't just safety concerns — they're insurance and reseller value concerns.
4. Strata-specific risk
For apartment buyers (and sellers), the questions multiply:
- Does the building have an EV/lithium-ion by-law?
- Is EV charging available in the building, on common property or private bays?
- Have other lot owners installed chargers?
- Are common-property bike rooms equipped for e-bike charging?
- Are there fire safety provisions in shared charging areas?
- Has the building's insurance premium been affected by lithium-ion-related questions at renewal?
- Is there a known fire history at the building?
- What's the load capacity of the main switchboard? (Critical for future EV-readiness)
What affects asset value
Positives
- A properly installed home battery is increasingly a value-add (CEC-approved, with documentation)
- An installed EV charger with Certificate of Electrical Safety is a small but growing positive
- Three-phase power becomes a meaningful differentiator
- An upgraded switchboard signals broader electrical capacity
- Modern, ventilated garage design with adequate clearances
- For apartments, the building having a clear EV-readiness plan and existing chargers installed
Negatives
- Non-compliant aftermarket battery installs without documentation
- Old switchboards (ceramic fuses, no RCDs) — known to need upgrade before any EV charger goes in
- Garages packed with lithium-ion devices, fuel, chemicals and clutter (a fire risk that's visible to inspectors)
- Strata buildings with no by-laws addressing lithium-ion
- Strata buildings with known fire incidents in shared charging areas
- Caravan or shed installs that compromise fire separation between accessory structures and the main dwelling
For buyers
Add these questions to your due diligence list:
- Ask the agent (in writing) whether a home battery, EV charger, or any other lithium-ion infrastructure is present, who installed it, and whether compliance documentation is available.
- Ask your building inspector to specifically look at the switchboard, charger install location, battery enclosure, garage layout and any lithium-ion-related modifications.
- Read the strata report carefully if buying an apartment. Look for: existing by-laws on EV/lithium-ion, recent AGM discussions of sustainability infrastructure, any insurance excesses or claims history, the building's known fire incidents (if any).
- Confirm insurance availability for properties with home batteries or EV chargers before exchanging contracts. Not all insurers will write all combinations.
- Plan ahead for what you'll add. If you intend to install a battery, EV charger, or e-bike charging area, factor the cost (and any switchboard upgrade) into your offer.
For sellers
If you're putting a property on the market with any of the above already installed, three things to do before listing:
- Locate and digitise the compliance paperwork. Certificates for solar, battery, EV charger, switchboard upgrade. Photograph everything. This material differentiates your listing from a comparable property with no paper trail.
- Get a quick electrical inspection if anything was installed by a now-defunct installer or you can't find the certificates. An updated Compliance Certificate is a cheap insurance against buyer hesitation.
- Tidy the garage and charging zones. A clean, well-organised garage with visible fire safety equipment, original chargers neatly stored, and no obvious clutter materially affects how buyers perceive the property's risk profile.
For real estate agents
Agents who can speak fluently to the lithium-ion questions buyers are starting to ask will close better than agents who can't. The basic competence:
- Know whether the property has a home battery / EV charger / solar
- Know whether the install was compliant and have the paperwork on hand
- Be able to point to the relevant strata by-laws for apartment buildings
- Be able to explain the federal/NSW rebate context to buyers who haven't been following it
- Be aware of insurance considerations that may affect specific buyers
The next step up is being able to talk meaningfully about fire safety setup as part of the property presentation. A garage with visible, mounted lithium-ion fire safety equipment reads as "this owner is on top of things" — and it's a low-cost, high-signal addition to a listing.
For conveyancers
The contract questions worth adding to your standard pre-exchange enquiries:
- Disclosure of solar/battery/EV charger installations
- Compliance certificates for all electrical work
- Any unapproved modifications affecting fire separation in garages or accessory structures
- For strata: existing and pending by-laws related to EV charging and lithium-ion storage
- For strata: AGM minutes referencing EV/lithium-ion discussions
- Insurance disclosures around the above
The fire safety equipment angle
A small kit of lithium-ion fire safety equipment is now arguably part of a sensible property handover, regardless of who's moving in. Three items cover most domestic risk:
- A lithium-ion-rated fire extinguisher mounted in the garage — extinguishers
- An EV fire blanket sized for a vehicle — blankets
- A small containment bag for any damaged battery — containment bags
Pre-built bundles are the simplest option:

The properties that hold value through the next decade are the ones where the lithium-ion infrastructure was installed properly, documented properly, and made safe.
