How to Challenge a PIP Assessment Decision UK: A Complete Step-by-Step Guide

You have received your PIP decision letter and the outcome is wrong. Either your claim has been refused, you have been awarded less than you expected, or you have been given a lower rate than your condition warrants. Before you accept the decision, it is worth understanding the statistics.

According to DWP’s own data, 66 percent of PIP appeals heard at an independent tribunal in the three months to March 2025 were decided in the claimant’s favour. And yet 65 percent of people who receive a negative mandatory reconsideration outcome never appeal to tribunal at all. They give up at the hardest point in the process and walk away from money they are entitled to.

This guide covers every stage of the challenge process: how to read your decision letter, how to write a mandatory reconsideration request that gives you the best chance of success, what happens if the DWP does not change the decision, and how to prepare for tribunal if it comes to that.

Start Here: Read the Decision Letter and Get the Assessment Report

Before you write a single word of your challenge, you need two documents: your decision letter and the healthcare professional’s assessment report. The decision letter tells you how many points you were awarded for each PIP activity. The assessment report tells you what the assessor said and observed during your assessment, and is the document the decision maker used to reach their conclusion.

If you do not have the assessment report, request it in writing from the DWP immediately. You are entitled to it and it is essential for an effective challenge. Many people who challenge PIP decisions find inaccuracies in the assessment report, including things they never said, activities they were assessed as being able to do despite describing significant difficulty, and a general picture of their condition that does not reflect what they told the assessor.

As you read through both documents, note every point where the assessor’s description does not match your actual experience. This is the foundation of your challenge.

Understanding the Two-Stage Challenge Process

Stage One: Mandatory Reconsideration

Before you can take a PIP decision to an independent tribunal, you must first ask the DWP to look at it again. This is called a Mandatory Reconsideration. You must request it within one month of the date on your decision letter. Citizens Advice guidance on PIP mandatory reconsideration explains the process in full. If you miss the one-month deadline, you can still apply up to 13 months from the decision date if you have good reasons for the delay, such as illness, bereavement, hospitalisation or not having understood the process. Include a brief explanation of the delay with your request.

A different DWP decision maker reviews your original decision. They are supposed to look at it afresh. In practice, around 20 to 25 percent of PIP mandatory reconsiderations result in a changed decision. This rate is lower than it should be for a genuine review process, and it is why many welfare rights advisers describe the MR stage as a procedural hurdle rather than a meaningful second chance. Do not be discouraged if the MR does not change the outcome. The tribunal stage, which follows, is where the majority of successful challenges happen.

The DWP does not have a statutory deadline for completing a mandatory reconsideration. In mid-2025 the average time was around 70 days, though this varies. During this time your existing PIP award, if any, continues at the rate currently in payment.

Stage Two: Independent Tribunal

If the mandatory reconsideration does not change the decision or does not change it sufficiently, you can appeal to the Social Security and Child Support Tribunal, which is completely independent of the DWP. You must appeal within one month of the date on your Mandatory Reconsideration Notice. The appeal is free. Submit it online or using form SSCS1 via GOV.UK’s appeal a benefit decision page. You will need your Mandatory Reconsideration Notice to do this, so keep both copies the DWP sends you.

Tribunal hearings for PIP are currently taking around six months from submission to hearing date, though this varies significantly by region. During this wait, your PIP payments continue at the rate in payment when you appealed. If the tribunal awards you a higher rate, the difference is backdated to the date of the original decision.

The tribunal panel consists of a judge, a doctor and a disability specialist. Their job is to decide what the correct award should be based on the PIP descriptors and the evidence before them. They are not there to assess your credibility or to catch you out. They are there to make a fair decision.

Important: the tribunal can look at your whole award, including components you are not disputing. Before you appeal, consider whether you might risk losing part of your current award. If you are uncertain, get advice from Citizens Advice or a welfare rights adviser before submitting your appeal form.

How to Write a Strong Mandatory Reconsideration Request

The mandatory reconsideration request is your formal challenge to the DWP. Simply saying you disagree with the decision is not enough. You need to identify the specific activities where you believe you were awarded the wrong number of points, explain why the correct score is higher, and provide evidence to support your position.

Structure Your Request by Activity

Go through each PIP activity in the daily living and mobility components. For each one where you believe the score is wrong, write a separate numbered section. State what score was awarded, what score you believe is correct, and why. Use the descriptor language from the PIP regulations so the decision maker can see exactly which descriptor you are claiming.

Example format for each activity:

Activity 4: Washing and bathing

Points awarded: 0

Points I believe I should receive: 3 (descriptor d: needs assistance to be able to wash their body)

Why: The assessment report states I can wash independently. This does not reflect what I told the assessor. I cannot step in and out of the bath safely due to my balance problems, which I described during the assessment. I rely on my husband to assist me. I attach a letter from my GP dated [date] confirming my balance difficulties and the risk of falls.

Apply this format to every activity where the score is wrong. The more specific you are, the harder it is for the decision maker to dismiss each point without engaging with it properly.

Address Inaccuracies in the Assessment Report

If the assessment report contains specific inaccuracies, challenge each one directly. Quote the inaccurate statement from the report, then explain what the accurate position is. If the assessor recorded that you walked into the room without difficulty and you were in significant pain throughout, say so. If the assessor recorded that you told them you can prepare a simple meal and you did not say this or described significant difficulty, say so.

You do not need to prove the assessor lied. You are asking the decision maker to prefer your account and your evidence over the assessor’s observations. A GP letter, a consultant report or a carer’s statement that supports your version of events is strong evidence.

Describe Your Worst Days, Not Your Average

PIP is assessed on whether you can perform activities on more than 50 percent of your days, reliably, safely, to an acceptable standard and in a reasonable time. If your condition fluctuates, describe both the better and worse days and explain which type of day is more frequent. Describing only your better days, or describing what you can manage on a good day, produces a lower score than your actual experience warrants.

The phrase ‘on my worse days’ should appear throughout your request. Describe specifically what you cannot do, cannot do safely, or cannot do repeatedly without severe consequences on those days.

Include New or Additional Evidence

You can submit new evidence at the MR stage that was not available or not submitted with the original claim. A GP letter, a specialist’s report, a care plan, a physiotherapy assessment, a mental health care coordinator’s report, a carer’s statement, a diary of daily activities. Any of these can change the picture significantly.

Ask your GP or specialist to write specifically about how your condition affects your ability to carry out daily activities, not just to confirm your diagnosis. A letter that says ‘this patient has Parkinson’s disease’ is less useful than one that says ‘this patient requires physical assistance with dressing and washing and is at significant risk of falls when mobilising independently.’

PIP Mandatory Reconsideration

[Address from your decision letter]

Subject: Request for Mandatory Reconsideration – PIP Decision Dated [date]

Dear Sir or Madam,

I am writing to request a mandatory reconsideration of the PIP decision dated [date]. I believe my award is incorrect for the following reasons.

I have requested a copy of the healthcare professional’s assessment report and have compared it against my own account of my daily life. I have identified a number of inaccuracies and areas where the scoring does not reflect my actual functional ability.

Activity 1: Preparing food

Points awarded: 0. Points I should receive: 4 (descriptor e: needs supervision or assistance to either prepare or cook a simple meal).

The assessment report states I am able to prepare a simple meal independently. This is not accurate. Due to my [condition], I have significant tremors in both hands that make using knives and hob controls unsafe. I have burned myself on two occasions. I rely on my partner to cook for me on the majority of my days. On days when my partner is not present I eat cold food or pre-prepared items. My GP’s letter of [date], attached as Exhibit A, confirms my tremor severity and the safety risk associated with cooking independently.

Activity 9: Engaging with other people

Points awarded: 0. Points I should receive: 4 (descriptor c: needs social support to be able to engage with other people).

The assessment report records that I communicate clearly and am able to engage with others. This observation is based on a 45-minute appointment conducted in controlled conditions with a professional. My ability to communicate in that setting does not reflect my functioning in practice. I experience severe anxiety in social situations, including with unfamiliar people. I require my sister to accompany me to all appointments and manage all communication with unfamiliar people on my behalf. My psychiatrist’s letter of [date], attached as Exhibit B, confirms that social anxiety is a significant feature of my condition and substantially impairs my daily functioning.

[Continue for each additional activity where the score is disputed]

I am requesting that the DWP reviews each of the activities above and awards points in accordance with the descriptors I have identified. I am happy to provide further information or to speak with a decision maker if that would assist.

Yours sincerely,

[Your name]

If the Mandatory Reconsideration Does Not Change the Decision: Going to Tribunal

If the DWP does not change the decision at the MR stage, do not stop here. As the statistics show, 66 percent of PIP appeals heard at tribunal are decided in the claimant’s favour. Submit your appeal within one month of the date on your Mandatory Reconsideration Notice using the SSCS1 form or the online appeal tool at gov.uk/appeal-benefit-decision. The SSCS1 form asks for the reasons for your appeal. Use the same structure as your MR request, addressing each activity and each inaccuracy. You can also submit the same evidence.

Before the hearing, you will receive a bundle of documents from the tribunal service including the DWP’s submission. Read it carefully. The DWP may raise new arguments or interpret evidence differently from your account. Note anything you want to address at the hearing.

At the Tribunal Hearing

The panel will ask you questions about your daily life. They want to understand what your condition is actually like to live with, day to day. Describe your worst majority days. Use concrete examples rather than general descriptions. Instead of saying ‘I find walking difficult,’ say ‘on most days I cannot walk from my bedroom to the kitchen without stopping to rest, and on bad days I use a wheelchair for any movement inside my home.’

You can bring a supporter, a friend, a family member or a representative to the hearing. A welfare rights adviser or disability charity representative who can speak on your behalf at tribunal significantly increases your chances of success. If you attend without a representative, the panel is required to assist you in presenting your case. You will not be disadvantaged for attending alone.

A critical finding from DWP’s own research, cited by Disability Rights UK, is that 59 percent of PIP appeals are won at tribunal based on the same evidence the DWP already held, with new evidence making a difference in only around one percent of cases. What changes the outcome is not new evidence but the tribunal’s independent application of the PIP criteria to the facts, and the claimant’s own account given in person. Attending the hearing, rather than submitting a paper appeal, gives you a significantly higher chance of success.

Common Reasons PIP Challenges Fail

• Not being specific enough. Saying ‘I disagree with the decision’ without identifying specific activities and specific descriptors gives the decision maker nothing to engage with. Every point of your challenge must identify an activity, the score you believe is correct and why.

• Describing good days. If your challenge describes what you can do on your better days, you will receive a lower score than your actual experience warrants. Describe your majority days, which are defined as more than half your days in a year.

• Not requesting the assessment report. Without the report you cannot identify the specific observations and inaccuracies that drove the scoring. Request it before you write your challenge.

• Missing the deadlines. One month from the decision letter for the MR. One month from the MR Notice for the tribunal. These are strict. Act promptly.

• Giving up after the MR. Only around 20 to 25 percent of MRs result in a higher award. The majority of successful challenges happen at tribunal. If the MR does not give you what you are entitled to, appeal.

• Not attending the tribunal hearing. Paper appeals have a significantly lower success rate than attended hearings. If at all possible, attend in person or by video.

Getting Help

Free help with PIP mandatory reconsiderations and appeals is available from Citizens Advice, whose advisers can help you structure your challenge, identify the correct descriptors and prepare for tribunal. Local welfare rights services, disability charities and law centres can often provide representation at tribunal hearings, which significantly improves outcomes. Search for ‘welfare rights [your area]’ to find what is available near you.

Disability Rights UK’s appeals and mandatory reconsiderations factsheet provides detailed guidance on the process including how to identify where a difference of opinion arises between you and the assessor and how to build evidence to address it.

If you want help drafting a mandatory reconsideration request that addresses every activity specifically and gives the DWP decision maker everything they need to change the award, the team at LetterLab can help you get the structure and language right before you submit.

Key Deadlines at a Glance

1. One month from the decision letter date to request a mandatory reconsideration

2. Up to 13 months if you have good reasons for missing the one-month deadline

3. One month from the Mandatory Reconsideration Notice date to appeal to tribunal

4. Keep your Mandatory Reconsideration Notice safe, you must attach it to your appeal form

5. Tribunal hearings currently taking around six months from submission to hearing date

The Key Takeaway: The Tribunal Is Where Challenges Succeed

The mandatory reconsideration stage is not where most PIP challenges are won. It is where most are abandoned. Only around 20 to 25 percent of MRs result in a higher award, and 65 percent of people who reach that stage give up rather than appeal. Those who do appeal to tribunal win in around two thirds of cases.

If your PIP decision is wrong, do not accept it. Request the assessment report. Write a specific, evidenced mandatory reconsideration request that addresses each activity and each inaccuracy. If the MR does not change the decision, appeal to tribunal and attend the hearing. Describe your worst majority days, not your best occasional ones. Take a supporter if you can.

The process is designed to be used without a solicitor. Free help is available at every stage. And the statistics show clearly that for the people who persist, the outcome is more often than not the correct award they were entitled to from the beginning.
