Child Disability Payment to ADP at 16 in Scotland

If your child gets Child Disability Payment (CDP) in Scotland, that payment does not last forever. As they approach 16, the door opens to Adult Disability Payment (ADP), the working age disability benefit delivered by Social Security Scotland. The move between the two is one of the most misunderstood points in the whole system, mostly because families expect it to happen by itself. It does not. This guide sets out the timeline, what actually changes and how to protect the money that is already coming in. Your payment cycle is designed to carry over unchanged, which our guide to ADP payment dates explains.

The window: 13 weeks before 16, up to the 18th birthday

There is a generous window for applying, and understanding it takes the panic out of the process. The earliest you can apply for ADP is 13 weeks before the young person's 16th birthday. The latest is their 18th birthday. Anywhere inside that roughly two year window, the timing is your choice.

That flexibility exists for a reason. Some young people are ready to move to ADP the moment they can, because their support needs are settled and they want their own award in their own name. Others are in the middle of exams, a health flare or a big life change, and it makes sense to wait until things are calmer. There is no penalty for choosing either.

Why it is not a rubber stamp

The most important shift is that getting Child Disability Payment does not guarantee getting Adult Disability Payment. CDP looks at the care and mobility needs of a child compared with other children of the same age. ADP looks at how a young adult manages a defined set of everyday tasks. They measure different things, so a strong CDP award does not automatically translate into an ADP award at the same rate, or any award at all.

ADP is scored against 12 activities: 10 for daily living such as preparing food, washing, dressing, communicating and managing money, and 2 for mobility, covering planning and following a journey and moving around. Each activity has descriptors that carry points.

All figures are weekly for 2026/27. Because the tests are different, an ADP award could be paid less than, the same as, or more than the Child Disability Payment it replaces. Treat the new application as a fresh case, not a renewal.

The transition timeline, step by step

Here is how the mechanics fit together once you decide to apply.

1. Open the application. The young person, or someone helping them, contacts Social Security Scotland to start the case. Part 1 covers identity, contact details, National Insurance number and bank details.
2. Complete Part 2. This is where you describe how the conditions affect the 12 activities. Once the application is started, there are up to 56 days (8 weeks) to submit it.
3. Submit before the 18th birthday. Both Part 1 and Part 2 need to be submitted before the young person turns 18 for the payment protection below to apply.
4. Payment aims to start at 16. Where they can, Social Security Scotland pays ADP from when the young person turns 16, so an early application need not mean an early loss of Child Disability Payment.

What the Scottish system does differently

The transition is far less stressful than the old cross-border process, and it helps to know why.

Your form is your case

Most ADP determinations are made on the papers, from the application and any supporting information. There is usually no face to face assessment. A consultation happens only when it is the only way to get the information needed, it is not a medical examination, and the invitation says in advance which parts they want to discuss. For a 16 year old, that means the written answers carry the weight, so describing a typical week honestly and fully matters more than performing on the day.

They help gather the information

Social Security Scotland has a duty to help gather supporting information, and case managers can request it themselves from the people you give permission to name. A young person moving from CDP often already has exactly the right paperwork on file: paediatric letters, an education, health and care record, a physiotherapy or occupational therapy report. One reliable piece of formal information about a condition responsible for more than a minor part of the young person's needs can be enough. You do not need a separate document for every symptom.

Reliability is built into the rules

Under regulation 7, an activity only counts as done if it can be done safely, to an acceptable standard, repeatedly and in a reasonable time. If the young person cannot do something reliably on most days, they are treated as unable to do it. Managing on a good day, with fatigue, pain or a wobble afterwards, is not the same as managing reliably, and the form should say so.

Rolling awards and challenging a determination

ADP awards run on a rolling basis with no fixed end date forcing a reapplication. Most are reviewed at some point, with light touch reviews generally set between 2 and 10 years apart and longer where needs are unlikely to change. If you disagree with the determination, you can ask for a re-determination within 42 days of the letter. Social Security Scotland then has 56 days to look again, and if they miss that deadline they must tell you, and you gain a direct right to appeal the original determination to the First-tier Tribunal for Scotland within 31 days of that notification.

Before you apply: get a full picture

Moving to ADP can affect other benefits in the household, so it is worth a benefits check first. A young person over 16 may become eligible for support in their own right, and a parent's entitlements can shift once the young person's benefit changes hands. You can talk the decision through with a parent, guardian, carer or support worker, and you can ask for free, independent help from Social Security Scotland's advocacy service. If someone provides regular care for the young person, they may be able to claim Carer Support Payment, the Scottish replacement for the old UK carer benefit.

Take your time inside the window, get the paperwork lined up, and submit before the 18th birthday. Do that and the move from Child Disability Payment to Adult Disability Payment becomes a planned handover rather than a scramble.

Some conditions first appear in exactly these years, keratoconus among them. If that applies, our guide to ADP for keratoconus covers what to write.

Frequently Asked Questions

Does Child Disability Payment turn into ADP automatically at 16?

No. The move is not automatic. You have to make a fresh ADP application so Social Security Scotland can look at how the condition affects the young person as a young adult. Child Disability Payment does not simply convert, because the two payments use different rules.

When can I apply for ADP if I get Child Disability Payment?

The earliest you can apply is 13 weeks before the 16th birthday, and the latest is the 18th birthday. Within that window the timing is your choice, so you can apply as soon as you are ready or wait until closer to 18.

What happens to Child Disability Payment if I do not apply?

If you do not apply, Child Disability Payment will usually stop at 18. If you do apply and submit both parts before the 18th birthday, CDP carries on being paid after 18 while Social Security Scotland processes the ADP application.

Could my ADP be less than my Child Disability Payment?

Yes. Because ADP uses different rules, it could be paid less than, the same as, or more than the Child Disability Payment it replaces. The move may also affect other benefits, so get a benefits check before you apply.

How does the ADP application work for a young person?

You open your case in Part 1, then complete Part 2, which asks how your conditions affect the 12 activities. Once you start you have up to 56 days to submit it, and both parts need to be in before the 18th birthday. Where they can, Social Security Scotland pays ADP from when you turn 16.

What if I disagree with my ADP determination?

Ask for a re-determination within 42 days of the letter. Social Security Scotland has 56 days to respond, and if they miss it you can appeal to the First-tier Tribunal for Scotland within 31 days of the outcome.

Can I get help deciding whether to apply?

Yes. Talk it through with a parent, guardian, carer or support worker, or ask for free help from Social Security Scotland's independent advocacy service. You can also call 0800 182 2222 before you start.
