Key takeaways
- An NDIS service agreement is the contract between you and your provider. It sets out what supports you get, when, and what they cost.
- Agreements are required for Specialist Disability Accommodation, and strongly recommended for everyone else.
- The three clauses that cause the most disputes are cancellation terms, travel charges, and the notice period for ending the agreement.
- You can negotiate. A service agreement is not a form you simply sign.
- Never sign an agreement that does not state the rate being charged.

What an NDIS Service Agreement Is
A service agreement is a written contract between you and a provider. It records what supports the provider will deliver, how often, at what price, and what happens if either side wants to change or end the arrangement.
It is not an NDIS document. The NDIA does not write it, approve it or hold a copy. It is an agreement between two parties, which is exactly why the detail matters and why terms differ from provider to provider.
Good providers use it to set clear expectations. It protects you as much as it protects them, provided you read it.
When You Must Have One
A written service agreement is required where a participant receives Specialist Disability Accommodation. For other supports it is not legally mandatory, but the NDIS Commission expects registered providers to have clear agreements in place, and going without one leaves you with nothing to point to when there is a disagreement.
If a provider tells you an agreement is unnecessary for a regular ongoing support, treat that as a reason to be more careful, not less.
What Every Agreement Should Include
| Section | What to look for |
|---|---|
| Supports provided | Named specifically, not just support services |
| Frequency and duration | How many hours, how often, over what period |
| Price | The actual rate, and the support item number |
| Start and end dates | Usually aligned to your plan dates |
| Cancellation policy | Notice required and what is charged |
| Travel | Whether it is charged and how it is calculated |
| Notice to end | How much notice each side must give |
| Complaints process | How to raise a problem and who to contact |
| Responsibilities | Both yours and the provider’s |
The price section is where most agreements are weakest. An agreement saying charges will be in line with the NDIS price limits tells you nothing about what you will actually be charged. Ask for the number.
Clause by Clause: What Fair and Unfair Look Like
Agreements are rarely dishonest. They are usually written by a provider protecting the provider, and nobody has ever asked them to change it. Here is what the same clause looks like written fairly and written badly.
| Clause | Reasonable version | Push back on this |
|---|---|---|
| Notice to end | A stated number of days, the same for both sides, in writing. | Notice required from you but not from the provider, or a period longer than a month. |
| Cancellation | Names the notice required and says the provider may claim only within the limits set by the NDIS pricing schedule. | A flat fee, a fee for any cancellation regardless of notice, or a percentage the agreement invents itself. |
| Rates | States the actual hourly rate for each support and time band, and says rates follow the current price limits. | Refers only to the price guide without naming a rate, so you cannot check anything. |
| Travel | Says travel is charged only where the pricing schedule allows it, and names the maximum. | A blanket travel charge per visit, or a call out fee. |
| Term | Runs to the end of your current plan, or twelve months, whichever comes first. | Automatic rollover with no end date, or a term that outlasts your plan. |
| Changing supports | You can add, reduce or change supports by agreement, in writing. | Changes only at the provider’s discretion, or a minimum weekly hours commitment. |
| Exclusivity | Silent. You may use other providers. | Any clause requiring you to use this provider for all supports of a type. |
None of the right hand column is illegal. All of it is negotiable, and the NDIA guidance on making a service agreement is explicit that you can suggest changes before signing.
Cancellation Terms, the Number One Dispute
Providers can claim for short notice cancellations under the NDIS rules, and most agreements include this. What varies is how it is written.
Look for three things. How much notice is required. What percentage of the support fee is charged. Whether there is any allowance for cancellations you could not avoid, such as a hospital admission.
Some agreements include a limit on how many short notice cancellations can be claimed in a plan year. That is worth asking for if it is absent, particularly if your health means cancellations are likely.
Travel Charges
Provider travel can be claimable, and it is a legitimate cost. It should also be transparent.
The agreement should say whether travel is charged, how it is calculated, and whether it is shared between participants when a worker sees more than one person on a trip. If a provider bills travel for a full journey while also billing another participant for the same journey, that is worth raising.
Ending the Agreement
Both you and the provider can end a service agreement. The agreement sets the notice period, commonly two to four weeks.
Watch for a mismatch. An agreement that lets the provider give two weeks notice but requires you to give eight weeks is unbalanced, and you can ask for it to be evened up before signing.
Also look for what happens in an emergency or where the relationship has broken down. A good agreement allows either side to end it immediately in defined serious circumstances.
A Worked Example: The Clause That Costs You
Take a participant with a standard weekday morning support, three hours, three days a week.
The agreement says cancellations require seven days notice and the provider may claim the full fee otherwise. That sounds harsh but broadly tracks how cancellation claiming works for disability support worker supports, so on its own it is not a red flag.
The problem is a second clause a few lines down: a minimum of nine hours per week for the term of the agreement. Read together, those two clauses mean that a fortnight in hospital, where nobody could have given seven days notice, is billed at nine hours a week regardless.
| What happens | Hours claimed | Cost at $73.58 |
|---|---|---|
| Two weeks of support delivered | 18 | $1,324.44 |
| Two weeks in hospital, minimum hours clause applied | 18 | $1,324.44 |
The same money leaves the plan either way, and the second fortnight bought nothing. Over a year, an unlucky run of illness on that agreement can quietly remove several thousand dollars of core funding.
The fix is one sentence, asked for before you sign: that cancellation claims will only be made as permitted under the current NDIS pricing schedule, and that minimum hours do not apply where you are in hospital or in respite. Most providers will agree to it. A provider who will not has told you something useful.
Red Flags to Watch For
- No price stated, only a reference to the price guide
- Automatic renewal without a fresh conversation
- Exclusivity clauses preventing you using another provider for anything
- A notice period longer than four weeks for you to exit
- Charges for services not described anywhere in the document
- No complaints process or no mention of the NDIS Commission
- Pressure to sign on the spot without time to read it
That last one is the clearest signal of all. Any reputable provider will give you the agreement to take away and read.
When You Need a New Agreement, Not an Amended One
People tend to sign one agreement and leave it running for years. The NDIA sets out three moments where a new agreement is the right move rather than a verbal tweak.
You are starting new supports with a provider you already use
This is the one everybody skips. Your cleaner starts also doing shopping, or your support worker starts driving you to appointments. The support type changed, the rate changed and the risk changed, but the agreement still describes the old arrangement. If a dispute ever comes up, the agreement is the document that gets read, and it will not mention the thing you are arguing about.
You are starting with a new provider
Always a new agreement. Verbal arrangements with a new provider are the single most common source of the invoice surprises people write to us about.
You have a new plan
A new plan usually means new budgets and often new goals. An agreement written against your old plan may commit you to hours your new budget cannot carry. Reviewing every agreement when a plan changes is a half hour job that prevents an overspend you cannot undo.
A practical habit: keep a single folder, digital or paper, with the current agreement for every provider and the date you signed it. When your plan changes, work down the folder. If you have a support coordinator, this is exactly the sort of thing to hand them.
What You Can Negotiate
More than most participants realise. Notice periods, cancellation limits, which specific workers support you, the days and times, how travel is handled, and how the agreement is reviewed can all be discussed.
You can also ask for a shorter initial term, for example three months, so both sides can see whether the arrangement works before committing for the full plan period.
What You Can Insist On, Whatever the Agreement Says
Some things are not up for negotiation because they sit above the agreement. A clause cannot sign them away.
- Registered providers must not add extra charges on top of the support cost. The NDIA has been explicit that gap fees, credit card surcharges and similar additional fees are not allowed.
- You can change providers at any time. An agreement can set a notice period. It cannot stop you leaving.
- You can complain to the NDIS Quality and Safeguards Commission without going through your provider first, and without their permission.
- You can ask for the agreement in a language, format or communication method you actually understand, and the provider should support you to understand it.
- You can bring someone with you. A family member, a friend, a support coordinator or an advocate can sit in when the agreement is explained.
Worth saying plainly: signing is not a formality you owe the provider. Nobody can require you to sign on the spot, and asking to take it home and read it is a completely normal request that good providers expect.
Before You Sign Checklist
- Take it away and read it properly, do not sign in the meeting
- Confirm the rate in dollars, not a reference to the price guide
- Read the cancellation clause twice
- Check the notice period is the same for both sides
- Confirm how travel is charged and shared
- Check the supports listed match what you actually asked for
- Ask someone you trust, or your support coordinator, to read it too
- Keep a signed copy

Frequently Asked Questions
1. Do I have to sign an NDIS service agreement?
Only Specialist Disability Accommodation legally requires one. For other supports it is not mandatory, but it is strongly recommended because without one you have nothing in writing if a dispute arises.
2. Can I negotiate a service agreement?
Yes. Notice periods, cancellation terms, travel arrangements, days and times, and the length of the initial term are all commonly negotiated.
3. What should a service agreement include?
The specific supports, frequency and duration, the price and support item numbers, start and end dates, cancellation and travel terms, notice to end, a complaints process, and both parties’ responsibilities.
4. Can a provider charge me for a cancelled appointment?
Yes, where you cancel within the notice period set out in your agreement and the NDIS rules allow it. Check what notice is required and what percentage is charged before you sign.
5. How do I end a service agreement?
Give notice in writing as set out in the agreement, commonly two to four weeks. Keep a copy of what you send and the date you sent it.
6. What if the provider will not change a clause I am unhappy with?
You are not obliged to sign. You can use a different provider. If you have already signed and there is a serious problem, raise it with the provider, then your support coordinator, then the NDIS Quality and Safeguards Commission.
