ESA for Chronic Migraines: How to Describe Your Limitations on the WCA

Updated May 2026 - Based on current WCA descriptor framework

Chronic migraines - occurring 15 or more days per month - cause severe headaches, nausea, light/sound sensitivity, cognitive dysfunction, and inability to function during attacks. If your attacks are dominated by sharp, stabbing facial pain rather than a typical headache, our guide on ESA for trigeminal neuralgia may describe your condition more closely.

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

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

Consciousness - Directly affected by chronic migraines
Standing and sitting - Directly affected by chronic migraines
Learning tasks - Directly affected by chronic migraines
Personal action - Directly affected by chronic migraines
Getting about - Directly affected by chronic migraines
Awareness of hazards - Directly affected by chronic migraines

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 Chronic Migraines on the ESA50/UC50 Form

The biggest mistake claimants with Chronic Migraines 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 chronic migraines, 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.

Common mistake: Don't say "I have Chronic Migraines" and leave it at that. Instead, describe specifically how Chronic Migraines prevents you from performing each activity reliably, repeatedly, and to an acceptable standard for the majority of the time. Always think about an 8-hour working day, 5 days a week.

Support Group (LCWRA) for Chronic Migraines

If your chronic migraines 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 Chronic Migraines

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

Key principle: Always describe your WORST typical day, not your best. If your condition varies, make clear how often bad days happen and what you cannot do on those days. The WCA asks about the "majority of the time" - if you struggle more than half the time, say so.

How much could your ESA be worth?

The amount depends on whether you reach the 15-point threshold for Limited Capability for Work, and whether you qualify for the Support Group (LCWRA). As a rough starting point, enter your main condition below to see the kind of figure a successful claim can reach. It is only an estimate - your real award depends on how the Work Capability Assessment scores your difficulties across the 17 activities.

Frequently Asked Questions

Can you get ESA for chronic migraines?

Yes, you can claim ESA (or the equivalent Limited Capability for Work element of Universal Credit) for chronic migraines. The Work Capability Assessment does not award benefit for the diagnosis itself - it looks at how your migraine attacks limit what you can do reliably and repeatedly in a work setting. If attacks force you to stop, lie down, or avoid screens and noise on most days, you can score points across several activities.

How many WCA points can chronic migraines score?

There is no fixed score for migraines - you need 15 points in total across the 17 activities to be found to have Limited Capability for Work. Migraines often draw points from activities such as consciousness, learning tasks, getting about, and coping with social situations, and physical and mental points are added together. Only the single highest-scoring descriptor in each activity counts, so focus on your worst typical level for each one.

Does the reliability rule help migraine claims?

Yes, and it is often the strongest argument. You must be able to do an activity reliably, repeatedly, safely and in reasonable time for the majority of the time, so if migraines stop you doing something on more than half your days you should be treated as unable to do it. Make clear how many days a month you lose to attacks and what you cannot do during and after them.

Can I get into the Support Group with migraines?

It is possible but less common, as the Support Group (LCWRA in Universal Credit) needs a Schedule 3 descriptor, 15 points on a single activity, or the substantial-risk rule. If frequent severe attacks mean that being required to undertake work-related activity would put your health at substantial risk, ask your GP or neurologist to say so in writing. The Support Group pays more (around £145.90 a week for 2026/27) and removes work-related requirements.

What evidence helps a migraine ESA claim?

A headache or migraine diary is particularly useful, recording how often attacks happen, how long they last, and what you cannot do during them. Add GP or neurology letters, prescription records for preventive and acute medication, and notes on side effects such as drowsiness from triptans or preventers. Ask each professional to comment on your work-related limitations rather than just the diagnosis.

What is the most common mistake people with migraines make?

The biggest mistake is describing only a good day or only the diagnosis, rather than the impact of a typical bad day. Because migraine is often invisible and fluctuating, assessors can underestimate it, so spell out the recovery period, the cognitive fog, and how unpredictable attacks make consistent work impossible. Always describe your worst typical day and how often it occurs.

What if my migraine claim is refused?

If you are turned down or placed in the wrong group, you can challenge it by asking for a Mandatory Reconsideration, and if that fails you can appeal to an independent First-tier Tribunal. Many decisions are changed at these stages, often because the original form did not explain limitations in work-related terms. Keep your migraine diary and any new medical evidence to support the challenge.

Evidence to Support Your Claim

Strong evidence is crucial for a successful WCA. For Chronic Migraines, 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 Chronic Migraines 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.
