SIL vs SDA: what's the difference?
SIL (Supported Independent Living) funds support workers who help with daily tasks at home. SDA (Specialist Disability Accommodation) funds specially designed housing for participants with extreme functional impairment or very high support needs. SIL is the help, and SDA is the home. A participant can have either one, or both.
| SIL | SDA | |
|---|---|---|
| What it funds | Support workers and supervision | The dwelling (specialist housing) |
| Who provides it | A registered SIL provider | A registered SDA provider (the housing provider) |
| Rent and living costs | Not covered | Participants usually pay a rent contribution |
| Can you have one without the other? | Yes. Many people get SIL in ordinary rental housing, and some SDA residents get their support from a different provider. | |
Same provider for both?
Some organisations provide both SIL and SDA. Having separate providers can make it easier to change your support provider without having to move house. It's worth asking about this before you sign anything.
Common questions
Do I need SDA to get SIL?
