SDA and SIL: the difference between housing and support

How to separate specially designed housing from the workers who assist you at home, including the costs and agreements to check.

SDA and SIL answer different questions. Specialist Disability Accommodation is about specially designed housing. Supported Independent Living is about the assistance a person needs with daily life.

You may hear them mentioned together, but approval for one does not automatically fund the other.

What SDA covers

SDA is for eligible people with extreme functional impairment or very high support needs. It relates to the design of the dwelling and has its own eligibility and funding requirements.

The four design categories address different needs. They are not a simple ladder where the highest label is the best home for everyone. Ask which features fit your own assessment and circumstances.

What SIL covers

SIL funds assistance or supervision with daily tasks for people who need a high level of support, including overnight. It can include personal care, meals and household routines under the agreed arrangement.

It does not fund the house, rent, groceries or ordinary household bills. Occasional visits at home may use another support arrangement rather than SIL.

Keep the agreements separate

A housing provider or landlord may be different from the support provider. Ask who is responsible for the tenancy, repairs, workers and support costs.

Changing a support provider does not automatically transfer or end a tenancy. Read both agreements and seek relevant advice about your situation before making commitments.

Compare what your day would involve

A well-designed building still needs the right support arrangements. Ask about privacy, access, overnight assistance, individual and shared hours, and how you can request changes.

If considering housemates, include your preferences and the way shared spaces and support would work. A vacant room alone doesn’t establish a suitable living arrangement.

Use the official information

Read the NDIA’s SDA explanation and SIL guidance with your own plan.

Vana Care accepts enquiries about SIL support. Contacting our team starts a discussion about the assistance requested, rather than confirming a property, funding or vacancy.
