In short. Registered providers have been audited by the NDIS Quality and Safeguards Commission and are approved for specific supports. Unregistered providers have not been audited. Which one you can use depends on how your plan is managed, not on which one is better. And from 2026, some supports cannot legally be delivered by an unregistered provider at all.
Why this question comes up
Someone tells you to use a registered provider. Someone else says the good ones are unregistered and cheaper. A third person says it does not matter. All three are partly right, which is why it is confusing.
The honest answer is that registration tells you one specific thing: this provider has been audited against a set of standards, and the Commission knows who they are. It does not tell you whether they will turn up on time or whether your support worker will be any good. Plenty of unregistered providers are excellent. Some registered ones are not.
What registration does give you is a paper trail, an oversight body, and somewhere to go when something goes wrong.
What being registered actually involves
To register, a provider applies to the NDIS Quality and Safeguards Commission and nominates the registration groups they want to deliver. Each group is a category of support with its own number.
An approved auditor then checks them. Depending on the groups, that is either a verification audit, which is lighter and looks mostly at documents and qualifications, or a certification audit, which is a full assessment against the NDIS Practice Standards. A certification audit involves an auditor coming into the business, reading policies, checking records, and interviewing participants.
Registration is not permanent. It runs on a cycle, it comes with conditions, and it can carry non-conformities the provider has to fix. A provider can also be registered for some supports and not others, which is the part most people miss. There is more on how to read that in our guide to NDIS registration groups and on what an audit involves in what an NDIS registration audit actually involves.
What unregistered providers can and cannot do
An unregistered provider is not doing anything wrong. Registration is voluntary for most supports, and many sole traders, small teams and allied health professionals choose not to register because the audit cost is high relative to their size.
What they cannot do:
- They cannot deliver supports that are subject to mandatory registration.
- They cannot deliver specialist behaviour support, or use regulated restrictive practices.
- They cannot be paid directly by the NDIA, which matters for how your plan is managed.
The rule that actually decides it: how your plan is managed
This is the part that answers the question for you personally.
NDIA-managed. The NDIA pays your providers directly. You can only use registered providers. No exceptions.
Plan-managed. A plan manager pays your invoices for you. You can use registered or unregistered providers. This is the most flexible option and it is why a lot of people choose it.
Self-managed. You pay providers yourself and claim it back. You can use registered or unregistered providers, and you carry the admin.
You can have a mix across one plan. So the practical question is not “is registered better”, it is “what does my plan allow, and what am I comfortable managing”.
What changed in 2026
Registration stopped being fully voluntary for some supports.
From 1 July 2026, supported independent living providers and NDIS digital platform providers moved into mandatory registration. Providers already delivering supported independent living must be registered or have applied to register by 1 October 2026. Delivering supported independent living without registration on or after 1 July 2026 can breach the NDIS Act, with penalties that include imprisonment and fines.
The Commission’s reasoning was that reviews identified higher risks to participant safety in these settings, so they should carry independent audits, suitability assessments, reporting obligations and worker screening.
If you receive supported independent living, this affects you directly. We wrote a separate guide on how to check your SIL provider’s registration, and it takes about two minutes.
Sources: NDIS Commission, mandatory registration for SIL and the NDIA announcement. Check both for the current position before you act, because reform timelines move.
What you actually get with a registered provider
Set aside the paperwork. Here is what registration buys you in practice.
An oversight body that is not the provider. If something goes wrong and the provider does not fix it, the NDIS Commission can act. You can call them on 1800 035 544. With an unregistered provider your options are consumer law and the courts, which is a much longer road.
Audited processes for the things that matter when they fail. Incident management, complaints handling, worker screening, and how the provider responds when a support worker does something wrong. You hope never to need these. When you do need them, you need them to already exist.
Worker screening. Registered providers must verify that everyone in a risk assessed role holds a valid NDIS Worker Screening Check or has a valid application in progress before they start working with participants.
A verifiable identity. You can look up a registered provider and confirm they exist, what they are approved for, and who owns them.
What registration does not tell you
Be clear about the limits, because a lot of marketing implies otherwise.
Registration does not tell you whether the provider has capacity for you. It does not tell you whether workers stay or leave every few months. It does not tell you whether anyone answers the phone at five o’clock. It does not tell you whether they will decline a referral honestly or take it and then struggle.
Those are the things that determine whether a provider works for you, and none of them appear on a registration certificate.
How to check any provider in two minutes
- Ask for the legal entity name their registration sits under. It is often different from the trading name on the website.
- Ask for the registration number.
- Ask which registration groups they hold, by number.
- Ask whether they were verified or certified, and by which auditor.
- Confirm it independently with the NDIS Commission on 1800 035 544, or through the NDIS provider finder.
Any registered provider can give you all five in a single email. If it takes a week, that tells you something too.
Questions worth asking either way
Whether the provider is registered or not, these are the ones that separate them:
- Who answers the phone after hours, and what happens if a shift falls through?
- How long has my support worker been with you?
- What do you do when a worker and a participant are not a good match?
- What are you not able to help with?
- How do I make a complaint, and who reads it?
A provider who answers the last two plainly is usually worth talking to further.
Where we sit
Serenica Support is a registered business name of Warsan Group Pty Ltd, ABN 36 645 979 906, a registered NDIS provider, registration number 4-LOHEV53. You can verify that with the NDIS Commission rather than taking our word for it.
We hold eleven registration groups and we publish all of them with their numbers on our services page. We are not registered for support coordination, plan management, therapeutic supports, specialist behaviour support or high intensity daily personal activities. If you need those, we will say so and point you somewhere else.
General information only. This is not advice about your plan. For questions about your own NDIS plan, speak to your support coordinator, your local area coordinator, or the NDIA on 1800 800 110. For concerns about a provider, the NDIS Commission is on 1800 035 544.
Not sure whether your plan lets you use a particular provider? Tell us how your plan is managed and what you are trying to arrange, and we will tell you straight whether we can help or whether you need someone else. Make a referral or call 1800 770 781.
