ADP Refused? How to Challenge a Determination

A refusal is not the end. Nearly half of completed re-determinations are allowed. Here are the three deadlines, in order, and where to start.

Updated July 2026 · 8 min read

The short version

A refusal is not the end, and in Scotland it is not even the last word on the same paperwork. You have 42 days from the date on your determination letter to ask for a re-determination, which is a fresh look by a different member of staff. Social Security Scotland then has 56 days to respond. If that still goes against you, you have 31 days to appeal to the First-tier Tribunal for Scotland. Nearly half of completed re-determinations are allowed, so the odds are far better than most people assume.

Refusals are common, and so are successful challenges

46%
Of the re-determinations completed by 30 April 2026, 46 per cent were allowed and 50 per cent disallowed. At the next stage, 53 per cent of decided appeals were upheld. For context, of 419,690 applications decided, 44 per cent were authorised and 53 per cent denied, so being refused first time round puts you in a very large group.

Those numbers are worth sitting with for a minute, because the most expensive reaction to a refusal is to assume it was correct and start again from scratch. A fresh application restarts every clock and throws away the challenge you were entitled to.

The three deadlines, in order

42 days: ask for a re-determination
From the date on the determination letter, not the date you opened it. A different member of staff looks at your case again. Late requests are possible with good cause, up to a year.
56 days: Social Security Scotland responds
If it runs over, you get an immediate right to appeal the original determination straight to the tribunal, without waiting for the re-determination to finish.
31 days: appeal to the tribunal
From being told the re-determination outcome. The First-tier Tribunal for Scotland, Social Security Chamber hears it. Late appeals are possible with good cause, backstop one year.
Throughout: Short-term Assistance
If an existing award was reduced or stopped, you can be paid the difference while you challenge it, and it does not have to be paid back even if you lose.
You cannot skip straight to the tribunal. The re-determination is a required first stage, with one exception: if Social Security Scotland misses its own 56 days, you get a direct right of appeal on the original determination.

Read the letter before you write anything

The determination letter tells you which descriptor was awarded for each of the 12 activities and how many points that carried. That is the whole map of what went wrong, and it is more useful than any general sense that the decision was unfair.

Work activity by activity. For each one, the question is not whether the decision felt wrong but which descriptor should have applied and why, judged on whether you can do the activity safely, to an acceptable standard, repeatedly and within a reasonable time period. Most refusals turn on that last group of words rather than on a factual dispute.

Three patterns account for the majority of refusals we see described:

Two free tools for a determination that went wrong

The Determination Analyser takes your scores and shows where you should have scored higher. The Re-determination Letter generator turns that into a letter. Both free, no card needed.

What a re-determination request should contain

Short and specific beats long and angry. The request itself only has to say that you want a re-determination, but what you attach to it decides the outcome.

Scored zero across the board?

That is a different situation from falling two points short, and it usually means the form was read as describing no functional difficulty at all rather than as describing difficulty that did not quite reach a descriptor. The argument you need is different, and our guide to scoring zero points covers it.

If an existing award was cut

Apply for Short-term Assistance first, then challenge. It pays the difference between the old and the new amount, or the full previous rate if the award was stopped, and it runs through the re-determination and on through any appeal to the First-tier Tribunal. It is not repayable even if the challenge fails, and it is not available on a first application that was refused.

What Scotland does differently at this stage

Should you challenge or reapply?

Challenge, in almost every case where you are still within 42 days. A re-determination looks at the same period the original determination covered, which is the period you have already described and evidenced. A fresh application starts a new qualifying period and gives up the arrears you would have been owed if the original determination was wrong.

Reapplying makes sense in one situation: where your condition has genuinely got worse since the determination, and you want the new, worse position assessed rather than the old one corrected. Even then it is usually worth doing both, in the right order.

Our Re-determination Pack covers both stages, from the letter through to the tribunal submission. You can see what is in each option on the comparison page.

Frequently asked questions

My ADP application was refused. What do I do first?+
Read the determination letter properly before doing anything else, because it tells you which descriptor was awarded for each of the 12 activities and how many points that carried. Then request a re-determination within 42 days of the date on the letter. Do not start a fresh application instead: a re-determination looks at the same period you have already described, while a new application restarts the qualifying period and gives up any arrears you would be owed if the original determination was wrong.
How likely is a challenge to succeed?+
Better than most people assume. Of the re-determinations completed by 30 April 2026, 46 per cent were allowed and 50 per cent were disallowed. At the next stage, 53 per cent of decided appeals were upheld. No outcome can be promised in any individual case, but a refusal is very far from the end of the process.
What is the 42 day rule for ADP?+
You have 42 days from the date on your determination letter to request a re-determination. That is the date on the letter itself, not the date you opened it. If you miss it, a late request is still possible where you have a good reason, with an absolute backstop of one year from the determination letter.
What happens if Social Security Scotland misses the 56 days?+
You are notified and you gain an immediate right to appeal the original determination directly to the First-tier Tribunal for Scotland, without waiting for the re-determination to be finished. You have 31 days from that notification. Whether to use it or wait depends on your case, since the re-determination may still succeed and is usually quicker than a hearing.
Can I go straight to the tribunal without a re-determination?+
No, apart from one exception. The re-determination is a required first stage. The exception is where Social Security Scotland fails to respond within its 56 days, which gives you a direct right of appeal on the original determination.
Will my payments stop while I challenge a decision?+
If you were refused on a first application there is nothing in payment to stop. If an existing award was reduced or stopped by a later determination, apply for Short-term Assistance. It pays the difference, or the full previous rate where the award was stopped, and it continues through the re-determination and any appeal to the First-tier Tribunal. It does not have to be paid back even if the challenge fails.
How much does it cost to challenge an ADP determination?+
Nothing. Neither a re-determination nor an appeal to the First-tier Tribunal for Scotland carries a fee, and free help is available from Citizens Advice Scotland and local welfare rights teams. ADPexpert is a paid service for people who want the materials written for them, but no part of the official process costs money.
