SIL Provider Costs: Simple Breakdown for Families

Understanding what Supported Independent Living costs, and why, is one of the harder parts of choosing a provider. The figures on a quote can look arbitrary until you know what drives them, and families often compare packages without knowing what is inside each one.

This guide breaks down what SIL covers, how the pricing is calculated, and what to ask a provider for in writing before you decide.

What SIL Actually Covers

Supported Independent Living funds the day-to-day support that helps a person live safely in a shared or individual home. It generally includes:

• Everyday assistance with meals, cleaning and personal care
• Overnight support, either active or sleepover
• Help with routines, appointments and social activities
• Coordination with therapists and other services
• Skills development that builds independence

SIL is funded through the NDIS, and the pricing arrangements set limits on what providers can charge for each support they deliver. That is the protection to lean on when comparing quotes.

The Four Factors That Drive SIL Costs

Every SIL quote comes back to four things.

1. The Level of Support Required

The biggest factor is how much assistance the person needs across the day and night. A higher support ratio, such as one worker to one participant, costs more than one worker supporting two or three people, because more staffing hours are involved.

2. The Home and Living Arrangement

Costs shift with the property and the setup: whether the home is fully accessible, newly built or adapted, and whether it is shared. Shared homes often cost less per person because support worker hours are spread across residents.

3. Day Versus Night Support

Overnight support comes in two forms. Active support means staff are awake and working through the night; sleepover support means a worker sleeps on site and responds if needed. Active overnight support costs more, and the difference matters when you read a quote.

4. Supports Outside SIL

Therapy, community access, transport and capacity-building supports are funded separately from SIL. They are not part of the core cost, and a clear quote will not blur the line between them.

How SIL Pricing Is Calculated

SIL is not priced as a single rate. It is built up from the support a person needs, and the process works like this.

The provider prepares a roster of care: a document setting out the support to be delivered across a typical week, including the staffing ratio, the number of support hours and the type of overnight support. Each part of that roster lines up with a support item in the NDIS pricing arrangements, and each item has a price limit. The roster is submitted to the NDIA, which reviews it and approves funding that matches it.

The practical effect is that the total comes from the hours, the ratio and the support types rather than from a provider’s price list. Providers cannot charge above the price limits for the support items involved, so two quotes built on the same roster should be comparable. If one quote is much higher, ask what is in its roster that the other one leaves out.

What to Ask for in Writing

Before committing to a provider, ask for four things in writing:

• An itemised quote against the current price limits, showing each support item and its rate
• The staffing ratio proposed for day support and for overnight support, with the roster of care attached
• The type of overnight support, and whether it is active or sleepover
• What happens when the roster changes, such as during holidays, illness or a change in needs, and how those changes are priced

A provider who finds these questions difficult is telling you something. The good ones answer them as a matter of course.

What Is Not Included

Some everyday costs sit outside SIL funding entirely: rent or mortgage payments, food and groceries, utilities, personal items, and transport that is not funded through an NDIS transport budget. Ask how the house handles these costs, because the arrangement varies between properties.

Choosing a Provider

When you compare providers, check for:

• Transparent pricing, with quotes that line up against the price limits
• A roster of care that matches the person’s real support needs
• A comfortable, well-maintained home
• Support workers who treat residents with respect
• Opportunities for skill building and independence
• Clear communication with families and support coordinators

The Roster Matters as Much as the Rate

SIL pricing makes sense once you know it is built from hours, ratios and support types rather than from a headline rate. Ask for the itemised quote, the roster and the overnight support type in writing, check the figures against the price limits, and compare providers on exactly the same basis. That is how families avoid surprises, and it is a fair request of any provider.
