ESA for Bipolar Disorder: How to Describe Your Limitations on the WCA
Updated May 2026 - Based on current WCA descriptor framework
Bipolar disorder causes extreme mood swings between depression and mania (or hypomania) that make consistent employment extremely difficult. The unpredictable nature of episodes means you cannot reliably attend or function in a workplace the majority of the time.
The Work Capability Assessment (WCA) does not ask "do you have Bipolar Disorder?" - 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 Bipolar Disorder Affect?
Bipolar Disorder can affect several of the 17 WCA activities. The key ones to focus on are:
- Coping with change - Mood instability means you cannot cope with routine workplace changes
- Personal action - During depressive episodes, you cannot initiate or complete tasks
- Social engagement - Both manic and depressive episodes affect social interaction
- Behaviour - Manic episodes can cause inappropriate or risky behaviour in a workplace
- Learning tasks - Cognitive function fluctuates dramatically with mood episodes
- Awareness of hazards - Manic episodes cause impulsivity and poor risk assessment
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 Bipolar Disorder on the ESA50/UC50 Form
The biggest mistake claimants with Bipolar Disorder 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 Behaviour: "My bipolar disorder causes episodes of mania where I behave in ways that are inappropriate for a workplace. During manic episodes I talk excessively, make impulsive decisions, become irritable and aggressive when challenged, and take risks I would not normally take. During depressive episodes I cannot interact with anyone. These episodes are unpredictable and I could not reliably behave appropriately in a workplace the majority of the time."
For Personal action: "During depressive episodes, which last weeks at a time, I cannot initiate any personal action. I cannot get out of bed, wash, dress, or do anything productive without repeated prompting from my partner. In a workplace I would have no one to prompt me, and I could not start or complete any task independently."
Support Group (LCWRA) for Bipolar Disorder
Bipolar disorder frequently qualifies for the Support Group through the substantial risk regulation. The risk of manic episodes in a stressful work environment, or the risk of severe depressive episodes being triggered by work-related activity, means there would be a substantial risk to your health. Make sure your psychiatrist states this clearly.
Tips for Your WCA with Bipolar Disorder
- Describe BOTH manic and depressive episodes and how each affects work capability
- Explain the unpredictable nature - you cannot plan around episodes
- Mention medication side effects (lithium tremor, weight gain, cognitive dulling)
- Describe what happens between episodes - if you are not fully functional, say so
- Be honest about hospital admissions and crisis episodes
- Explain that the condition is long-term and episodes will continue despite treatment

ESAexpert generates tailored guidance for all 17 WCA activities based on your specific conditions. See exactly which descriptors apply to you and get ready-to-use language for your ESA50/UC50 form.
Get Your Personalised ReportEvidence to Support Your Claim
Strong evidence is crucial for a successful WCA. For Bipolar Disorder, 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 Bipolar Disorder 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.
