ESA for Diabetes: How to Describe Your Limitations on the WCA

Updated May 2026 - Based on current WCA descriptor framework

Diabetes - particularly type 1 or poorly controlled type 2 - causes blood sugar fluctuations, fatigue, neuropathy, and risk of hypoglycaemic episodes that affect work capability.

The Work Capability Assessment (WCA) does not ask "do you have Diabetes?" - 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 Diabetes Affect?

Diabetes can affect several of the 17 WCA activities. The key ones to focus on are:

• Consciousness - Directly affected by diabetes
• Awareness of hazards - Directly affected by diabetes
• Mobilising - Directly affected by diabetes
• Manual dexterity - Directly affected by diabetes
• Standing and sitting - Directly affected by diabetes
• Personal action - Directly affected by diabetes

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 Diabetes on the ESA50/UC50 Form

The biggest mistake claimants with Diabetes 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.

When completing your ESA50/UC50 form for diabetes, focus on how the condition prevents you from performing each activity reliably, repeatedly, and safely in a work context. Do not just list symptoms - explain what you cannot do and why. Think about an 8-hour working day, 5 days a week.

For each activity, describe your worst typical day. If your condition varies, explain the pattern - how many bad days per week, and what you cannot do on those days.

Support Group (LCWRA) for Diabetes

If your diabetes is severe enough that returning to work or work-related activity would pose a substantial risk to your health, you may qualify for the Support Group through the substantial risk regulation. Ask your GP or specialist to provide a letter specifically stating this risk.

Tips for Your WCA with Diabetes

• Always describe limitations in work-related terms, not just medical symptoms
• Think about reliability - can you do each activity consistently, every day, for a full working day?
• Mention medication side effects and how they affect your ability to function
• Describe your worst typical day, not your best
• If your condition fluctuates, explain the pattern and frequency of bad days
• Get supporting evidence from your GP or specialist that specifically mentions work-related limitations

Evidence to Support Your Claim

Strong evidence is crucial for a successful WCA. For Diabetes, 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 Diabetes 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.
