Home modifications, how SIRA explains the rules in Western Sydney

If you’ve suffered a serious motor accident injury in Western Sydney and need home modifications to recover, the NSW Compulsory Third Party (CTP) scheme may cover your costs. The State Insurance Regulatory Authority (SIRA) oversees claims under the Motor Accident Injuries Act 2017, which outlines what home changes are eligible. This article explains how SIRA assesses home modification requests, what evidence you’ll need, and how to challenge a decision.

What home modifications are covered under NSW CTP claims?

Under the CTP scheme, home modifications are considered a form of treatment and care benefit. These include changes to make your home safer or more accessible after a serious injury, such as:

  • Installing wheelchair ramps or handrails
  • Modifying doorways to accommodate mobility equipment
  • Adding non-slip surfaces in bathrooms
  • Installing shower chairs or grab rails

SIRA’s guidelines state that modifications must be directly related to your injury and necessary for your recovery. For example, a wheelchair ramp may be approved if your injury prevents you from using stairs.

How does SIRA determine eligibility for home modifications in CTP claims?

SIRA evaluates home modification requests based on two main factors: medical necessity and reasonableness. Medical reports from your treating practitioner must confirm that the modification is essential for your recovery. Additionally, the modification must be:

  • Cost-effective and proportionate to your needs
  • Likely to improve your ability to live independently
  • Not excessive or unnecessary

For instance, a SIRA decision in Western Sydney recently approved a handrail installation after a cyclist suffered a spinal injury, as it was deemed necessary to prevent falls. However, a request for a full home renovation was denied as it was considered excessive.

What evidence is required to support a home modification claim under CTP?

To support your claim, you’ll need to provide:

  • A detailed medical report from your doctor or physiotherapist explaining why the modification is necessary
  • A quote or estimate from a licensed builder or contractor
  • A statement from your treating practitioner confirming the modification’s medical necessity
  • Proof of ownership or tenancy of the property

SIRA may also request a site inspection to verify the modification’s suitability. Ensure all documents are submitted promptly to avoid delays.

How can claimants challenge a denied home modification request under SIRA rules?

If SIRA denies your request, you can appeal the decision by:

  1. Submitting a written objection within 28 days of receiving the decision
  2. Including new evidence or clarification that was not previously provided
  3. Requesting a review by a senior SIRA officer

Appeals are typically resolved within 4-6 weeks. If the decision remains unchanged, you may seek independent legal advice to explore further options.

Time limits and practical steps

You must notify SIRA of your home modification request within 52 weeks of the accident. If you’re unsure whether your modification qualifies, contact SIRA directly for guidance. Keep copies of all correspondence and documents to support your claim.

When to seek legal advice

While SIRA provides clear guidelines, interpreting them can be complex. A solicitor can help you:

  • Navigate SIRA’s application process
  • Challenge decisions based on incorrect interpretations of the law
  • Ensure all evidence is properly documented

Legal advice is particularly useful if your claim is denied or if you need to dispute a decision.

Next steps

If your request is denied, you can appeal or seek legal assistance. Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
