Platform lifts and stair lifts are both common home modification solutions in Australia, but they solve the problem in fundamentally different ways — and they suit different users.

A stair lift attaches a rail to the existing staircase and carries a seated user up and down. It requires minimal structural work, costs significantly less than a platform lift, and can be installed in most homes. The critical limitation: a stair lift cannot accommodate a wheelchair. The user must be able to transfer to a seated position unaided.

A platform lift is a vertical lift that carries a platform — large enough for a wheelchair and a carer — between floor levels. It meets the access requirements in AS 1735.14, qualifies for NDIS and aged care home modification funding, and provides genuine, consistent access for wheelchair users. The trade-off is cost and space: a platform lift requires a floor opening or dedicated space and costs $22,000–$50,000 installed.

For more information on platform lifts as a category, see our platform lifts overview.

The table below compares platform lifts and stair lifts across six factors that determine which product is appropriate for a given home and user. These are decision factors — use them to identify the right category before getting quotes.

Cost ranges are indicative ex-GST and vary by brand, configuration, and staircase type. An occupational therapist assessment is typically required before a home modification can be funded. Always confirm eligibility with your plan manager or aged care provider before proceeding.

Choose a platform lift if

  • You or a family member uses a wheelchair and needs full, independent access between floors
  • The access solution must also accommodate carers with equipment
  • You are planning a long-term home modification that may qualify for NDIS or aged care funding
  • The product must meet AS 1735.14 — which some funding programs require
  • You want a solution that serves any future user of the home, including guests who use a wheelchair

For platform lift options and cost guidance, see our platform lifts overview and platform lift cost guide.

Choose a stair lift if

  • The primary user is ambulatory or can transfer to a seated position unaided
  • Budget is a priority — a stair lift costs significantly less than a platform lift
  • You want minimal structural impact on the home
  • The staircase is straight (curved staircase models are more expensive but available)
  • The solution is medium-term — stair lifts can be removed or sold when no longer needed

Our recommendation

For wheelchair users or anyone planning a long-term home modification, a platform lift is the appropriate solution. It provides genuine access that is consistent regardless of the user's mobility, and it meets the compliance requirements that most NDIS and aged care funding programs reference.

For ambulatory users who need assistance on stairs and are not using a wheelchair, a stair lift is practical and significantly more cost-effective.

If you are unsure which category applies, consult an occupational therapist before purchasing. An OT assessment is required for most funded home modifications in any case — and the OT recommendation will carry weight with your plan manager or aged care provider.
