ESA for Arthritis: How to Describe Your Limitations on the WCA
Updated May 2026 - Based on current WCA descriptor framework
Arthritis - including rheumatoid arthritis, osteoarthritis, psoriatic arthritis, and ankylosing spondylitis - causes chronic pain, stiffness, fatigue, and reduced mobility that significantly affect the ability to work. The WCA specifically assesses physical capabilities that arthritis directly impacts.
The Work Capability Assessment (WCA) does not ask "do you have Arthritis?" - it asks how your condition affects your ability to perform 17 specific work-related activities. To score enough points for Limited Capability for Work (LCW), you need 15 points across all 17 activities combined. For the Support Group (LCWRA), you need to meet at least one Support Group descriptor.
Which WCA Activities Does Arthritis Affect?
Arthritis can affect several of the 17 WCA activities. The key ones to focus on are:
- Mobilising - Joint pain and stiffness affect walking distance and speed
- Standing and sitting - Arthritis makes remaining at a work station painful after short periods
- Reaching - Shoulder, elbow, or wrist arthritis limits reaching above head or across the body
- Picking up and moving - Joint pain reduces grip strength and ability to carry objects
- Manual dexterity - Hand and finger joint involvement affects fine motor tasks
- Getting about - Fatigue and pain make travelling to a workplace difficult
Remember, points from ALL activities are added together. Even scoring 6 points each on just three activities gives you 18 - well over the 15-point threshold.
How to Describe Arthritis on the ESA50/UC50 Form
The biggest mistake claimants with Arthritis make is describing their condition in medical terms rather than work-related terms. The WCA does not care about your diagnosis - it cares about what you cannot do reliably, repeatedly, and safely in a workplace context.
For Standing and sitting: "My rheumatoid arthritis causes severe pain and stiffness in my hips, knees, and lower back. I cannot remain at a work station for more than 20 minutes before I need to move because of significant discomfort. Even alternating between sitting and standing does not help - both positions become painful. Over an 8-hour working day, I would be unable to maintain any position at a work station the majority of the time."
For Manual dexterity: "The arthritis in my hands means I cannot pick up a coin or small object with either hand. My fingers are swollen and stiff, particularly in the mornings (lasting 2-3 hours). I cannot do buttons, use a keyboard accurately, or grip small tools. This affects me the majority of the time."
Support Group (LCWRA) for Arthritis
Arthritis may qualify for the Support Group if you meet a LCWRA descriptor - for example, if you cannot mobilise more than 50 metres on level ground without stopping due to significant pain. The substantial risk regulation may also apply if working would cause serious deterioration of your condition.
Tips for Your WCA with Arthritis
- Describe morning stiffness - how long it lasts and how it affects your ability to function
- Mention fatigue - arthritis-related fatigue is different from normal tiredness
- Explain flare-ups - how often they happen and how much worse they make things
- Be specific about which joints are affected and what you cannot do
- If you take biological drugs, steroids, or DMARDs, describe side effects
- Describe a typical day - not just the painful moments

Get Your Personalised ReportEvidence to Support Your Claim
Strong evidence is crucial for a successful WCA. For Arthritis, gather:
- GP or specialist letters confirming your diagnosis and how it affects your ability to work
- Prescription records showing medication and any side effects that affect function
- Fit notes or med3 certificates
- Hospital or clinic appointment records
- A personal diary showing how your condition varies day to day
Ask your GP to specifically mention how Arthritis affects your ability to perform work-related tasks - not just the medical diagnosis itself.
What if You're Rejected?
Around 2 in 3 ESA mandatory reconsiderations result in a changed decision. If you score 0 points or are placed in the wrong group, you should challenge the decision. The most common reason for failure is not describing limitations in work-related terms - which is exactly what ESAexpert helps you with.
