Upper Tribunal Rules on PIP Mobility Descriptors

A significant Upper Tribunal ruling has clarified how PIP mobility descriptors should be applied for claimants with fluctuating conditions, potentially affecting thousands of existing awards.

Upper Tribunal Ruling: PIP Mobility and Fluctuating Conditions

The Upper Tribunal has issued an important ruling clarifying how PIP mobility descriptors should be applied for claimants whose conditions fluctuate.

The Key Ruling

The Tribunal confirmed that when assessing PIP mobility, assessors must consider the majority of days — not just the best or worst days. For claimants with fluctuating conditions, this means:

If you can walk more than 20 metres on some days but fewer than 20 metres on the majority of days, you should be awarded the Enhanced Mobility component
Assessors cannot simply rely on a single assessment day to determine your typical ability

Who This Affects

This ruling is particularly relevant for claimants with:

Multiple Sclerosis (MS) — where symptoms fluctuate significantly
Lupus and other autoimmune conditions
Fibromyalgia
Chronic fatigue conditions
Arthritis — where pain levels vary day to day

What to Do If Your Award Was Based on a Single Assessment

If you believe your PIP mobility award was incorrectly assessed because the assessor only considered your condition on the assessment day (or based on a single snapshot), you may have grounds to challenge the decision.
