Get the PA4 report
Before you challenge anything, you need the report. Ring or write to the PIP number on your decision letter and request a copy of the PA4 assessment report. It is free. It normally arrives within 10 to 14 days.
The most common errors
- Snapshot bias. One moment of function extrapolated to every day. "Walked to the assessment room" becomes "can mobilise 200 metres". The reliability test requires repeatability, not a one-off.
- Misused informal observations. Neutral or masked behaviour read as evidence of capability. Sitting still can be dissociation, not calm. Fluent speech in a 40-minute call does not show a full working day.
- Missing all four reliability limbs. A conclusion of "can do the task" without asking whether it was safely, to an acceptable standard, repeatedly, and in a reasonable time.
- "Walked 200m" with no testing. Distance conclusions drawn from the room and corridor, not from a proper account of exertion, pain, aftermath and repeatability.
- Mental-health minimisation. "Presented as pleasant and cooperative" being used to imply capacity to engage with unfamiliar people, plan a journey, or manage complex tasks daily.
- Ignored evidence. Specialist letters, medication lists, or diaries not addressed in the report.
- Ambulatory aid ignored. Use of stick, crutch, or wheelchair not recorded, or recorded but not applied to the descriptor.
The four reliability limbs
Under Regulation 4(2A), a task counts only if you can do it safely, to an acceptable standard, repeatedly, and in a reasonable time. If the PA4 does not address a limb that applies, that omission is a rebuttable error.
How to rebut
- Quote the report by paragraph number.
- State the correct fact.
- Reference the specific evidence that supports the correction (form section, GP letter, diary date).
- Apply the reliability limbs by name.
- Ask for the descriptor to be scored on the corrected basis.
3-column rebuttal template
A structure you can copy into a Word document or the body of your MR letter. The example rows below are illustrative, they are not real cases.
| What the report says | What actually happened | Evidence that shows it |
|---|---|---|
| Example, para 12: "Walked from the waiting room without visible distress, therefore can mobilise 200m repeatedly." | Example: I walked the corridor once. I stopped twice, held the wall, and spent the rest of the day in bed. I have never walked 200m repeatedly. | Example: PIP2 Activity 12 free text; GP letter dated [date]; diary entries [dates]; physio discharge summary. |
| Example, para 18: "Pleasant and coherent throughout the assessment, therefore can engage with unfamiliar people daily." | Example: I masked for 40 minutes. I dissociated afterwards and could not speak for the rest of the day. I cannot engage with unfamiliar people reliably or repeatedly. | Example: CMHT letter dated [date]; supporter statement from [name]; diary entries covering the week of the assessment. |
| Example, para 23: "Prepared a simple meal earlier today, therefore Descriptor A applies." | Example: I microwaved food that my partner had left prepared. I have left the hob on three times in the last month and am supervised when cooking. | Example: partner supporter statement; OT report dated [date]; PIP2 Activity 1 free text. |
Replace every "Example:" line with your own paragraph reference, factual account, and evidence citation. Keep it neutral and specific.
What if the assessor lied?
If the report contains statements you never made, or clearly false records of what happened in the room, you have two separate tracks and can pursue both at once:
- Mandatory Reconsideration (MR) is what changes the decision. The MR letter should list each false statement, quote the report by paragraph, correct the fact, and cite the evidence. See the MR guide for the deadline and a free letter skeleton.
- A complaint to the assessment provider (Maximus, Capita or Ingeus, depending on your region) is what challenges the conduct itself. Write to the provider named on the PA4, quote the specific false statements, and ask for the complaint to be logged and answered under their published complaints procedure. Ask for a copy of the audio if the assessment was recorded (you have a right to request the recording of your own assessment).
The MR fixes the decision, the complaint puts the conduct on the record. Neither replaces the other.
Odds at MR and tribunal
26% of PIP mandatory reconsiderations cleared in the quarter ending April 2026 led to a change in award (28% over May 2021 to April 2026). Source: DWP, Personal Independence Payment: Official Statistics to April 2026, published 16 June 2026. 67% of PIP appeals decided at a tribunal hearing found in the claimant's favour (January to March 2026).

The practical read: a properly-written MR rebuttal is worth doing on its own merits, and it is the door to the far higher tribunal odds. Plan the rebuttal so the same argument is ready to lodge on an SSCS1 if you need to. Full walkthrough: PIP Mandatory Reconsideration 2026.

How do I get a copy of the PA4?
Ring DWP or write asking for a copy of the assessment report. It is free. Ask specifically for the 'PA4' (or PA5 for paper-based assessments). It usually arrives within 10 to 14 days.
What is snapshot bias?
The assessor treats one moment in the consultation as representative of every day. 'The claimant walked from the waiting room to the assessment room without visible distress' becomes 'able to mobilise 50m repeatedly'. It ignores fluctuation and the reliability test.
What are 'informal observations'?
Notes made about how you looked, sat, spoke, and moved during the consultation. Informal observations begin from the moment you enter (or the moment the call starts). They are heavily used by assessors and often misread neutral behaviour as evidence of capability.
Can informal observations be challenged?
Yes. Point to the reliability test: one observed moment does not show repeatability, safety, or acceptable standard over a typical day.
What if the report contains factual errors?
List each one in your MR letter: quote the report, state the correct fact, and reference supporting evidence. Factual errors that go to a scoring descriptor are strong grounds for reconsideration.
