Current as at 16 August 2026

How SIRA Approves Home Modifications for Serious CTP Injuries

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

If you've suffered a serious motor vehicle accident in Western Sydney and need home modifications to recover, the State Insurance Regulatory Authority (SIRA) oversees claims under the NSW Compulsory Third Party (CTP) scheme. SIRA determines whether modifications like ramps, handrails or bathroom adaptations are eligible, based on medical evidence and the severity of your injury. This article explains the legal rules, evidence required and practical steps to support your claim.

Key SIRA Rules for Home Modification Claims

Under the Motor Accident Injuries Act 2017, SIRA evaluates whether a modification is 'reasonable and necessary' to address the impact of your injury. For serious injuries, this involves:

  • Medical evidence showing how the injury affects daily living
  • Assessment of the modification's necessity to enable independent living
  • Cost justification based on standard industry rates

SIRA's guidelines state that modifications must directly address the injury's effects. For example, a spinal injury requiring a ramp to access your home would qualify, while a minor mobility aid might not. The injury must be severe enough to prevent safe, independent living without the modification.

What Evidence Matters for Your Claim

To support your home modification claim, gather:

  • Medical reports from your treating doctor or physiotherapist detailing your injury's impact
  • Occupational therapy assessments showing how the modification enables daily tasks
  • Quotes or invoices from approved contractors for the modification
  • Photos or diagrams of your home showing the modification's location and purpose
  • SIRA's 'reasonable and necessary' checklist (available on their website)

SIRA may also request a report from an independent assessor to evaluate the modification's necessity. Ensure all documentation clearly links the modification to your injury's effects.

Practical Steps for Claimants in Western Sydney

  1. Notify SIRA of your injury within 52 weeks of the accident (per Motor Accident Injuries Act 2017 s 3.11)
  2. Consult a medical professional to document how your injury affects daily living
  3. Submit a detailed claim form with all supporting evidence
  4. Request a SIRA assessor to evaluate the modification's necessity
  5. Appeal if your claim is denied by lodging a written objection within 28 days (per SIRA's internal procedures)

SIRA's approach in Western Sydney aligns with national guidelines but may involve local assessors familiar with regional housing standards. For example, a claimant in Western Sydney might need to demonstrate how a modification complies with local building codes, which could affect eligibility.

Time Limits and Dispute Options

You have 52 weeks from the accident date to notify SIRA of your injury (s 3.11). If your claim is denied, you can:

  • Appeal to the NSW Civil and Administrative Tribunal (NCAT) within 28 days of the decision
  • Seek independent legal advice to challenge SIRA's assessment of your injury's severity

Note that disputes over home modifications often hinge on whether the injury meets the 'reasonable and necessary' threshold. SIRA's guidelines state that modifications must be 'directly related to the injury's effects' and not merely 'convenient' (SIRA Internal Guidance Note 2022). This distinction is critical for serious injuries.

When to Seek Legal Advice

Consult a solicitor if:

  • SIRA denies your claim without explanation
  • You're unsure whether your injury meets the 'reasonable and necessary' threshold
  • You need help appealing a decision

Legal professionals can help you navigate SIRA's assessment process and ensure your claim reflects the full impact of your injury. Remember, every claim depends on its own facts, the above steps provide a general framework but cannot guarantee outcomes.
