Mobility Activity 2: Moving around
The notorious 20-metre rule sits in this activity. Distances are scored at 20m, 50m and 200m, all subject to the reliability test (safely, to an acceptable standard, repeatedly, and in a reasonable time).
Descriptors and points
Worked example: Fibromyalgia and chronic pain
You can walk to the kitchen but cannot manage more than 20 metres safely on most days without a stick. Apply the reliability test: descriptor d (more than 20 but no more than 50 metres with an aid) becomes descriptor e (no more than 20 metres) when you fail more than half the time. Score 12, enhanced Mobility.
Descriptor scored: E, 12 points.
Reliability test
Whatever descriptor you pick must apply to you safely, to an acceptable standard, repeatedly, and in a reasonable time. If you can only manage the activity on a good day, the next-higher descriptor usually applies. This is the single most common reason claimants are under-scored on assessment.
Source
Descriptors and points are taken from Schedule 1 of the Social Security (PIP) Regulations 2013. Interpretation guidance is in the PIP assessment guide (DWP, Feb 2026).
