What to Say at Your WCA Assessment (Phone, Video or Face-to-Face)

After submitting your WCA50 form, you may be called for a WCA assessment. This is usually conducted by phone, but can be by video or the WCA face-to-face assessment. The assessment is carried out by a healthcare professional (usually a nurse or physiotherapist) who will ask you questions about how your conditions affect your ability to work. Here is how to prepare.

What to expect

The assessment typically lasts 30-60 minutes. The assessor will ask about your health conditions, medication, daily routine, and how specific activities affect you. They are assessing you against the same 17 WCA activities and descriptors that your WCA50 form covers, so it helps to read up on the questions asked at a WCA before your appointment. If your health claim runs through Universal Credit, remember to keep sending fit notes on Universal Credit right up until the WCA decision is made.

Before the assessment

• Re-read your WCA50 form. Your answers should be consistent with what you wrote.
• Prepare examples. For each activity, have a specific example ready of when you could not do it.
• Ask for a recording. You have the right to request that the assessment is audio-recorded. Do this in advance.
• Bring someone with you. You can have a companion present. They can take notes and provide moral support.

What to say

Describe your worst typical days. If the assessor asks "can you sit in a chair?" do not answer based on your best day. Answer based on what happens the majority of the time.

Use WCA language naturally. Work phrases like "the majority of the time," "significant discomfort," "I cannot do this reliably," and "in a workplace this would mean..." into your answers.

Be specific about consequences. Do not just say "it hurts." Say "after 20 minutes, the pain in my lower back becomes so severe that I need to lie down for at least 30 minutes before I can sit again."

Mention what happens afterwards. If doing something causes a crash, flare-up, or worsening of symptoms, describe the aftermath. "If I walk to the shops, I need to rest in bed for the rest of the day."

Common traps to avoid

• "How did you get here today?" This is not small talk - they are assessing your mobility and ability to get about. If someone drove you, say so. If the journey was difficult, explain how.
• "What did you have for breakfast?" They are assessing your ability to prepare food and initiate tasks. If someone else prepared it, or if you skipped breakfast because you could not manage, say so.
• "Do you have any hobbies?" Be careful. Saying "I watch TV" can be used to argue you can concentrate. Say "I try to watch TV but I cannot follow plots because of brain fog. I often just stare at the screen."
• Do not say "I manage." "I manage" implies you can do the activity. Say "I struggle significantly" or "I cannot do this reliably."

After the assessment

Make notes about what was asked and what you said as soon as possible after the assessment. If you feel the assessor did not accurately capture your difficulties, you can submit additional evidence before the decision is made. If the decision is unfavourable, you have one month to request a Mandatory Reconsideration.

What the assessment is actually testing

It helps to understand what the assessor is listening for, because it is not what most people assume. The Work Capability Assessment does not measure how ill you feel or how serious your diagnosis sounds. It measures one thing only: limited capability for work. In plain terms, the question behind every question is whether your conditions stop you doing the kind of activities a job would require. That is a different test from PIP, which looks at daily living and getting around. Two people with the same diagnosis can score very differently on the WCA, because the score is built from function, not from the label on your medical notes.

The assessor scores you against the same 17 activities that appear on your WCA50 form - ten that are mostly physical (such as moving around, standing and sitting, reaching, picking things up, and continence) and seven that are mental, cognitive or social (such as learning tasks, coping with change, getting about, and dealing with other people). Each activity has a set of descriptors worth 0, 6, 9 or 15 points. Only the single highest descriptor that applies to you counts for each activity, and your points from every activity are then added together. Physical and mental points combine into one total. You need 15 points in all to be found to have limited capability for work. So when you answer a question, you are not just chatting - you are giving the assessor the raw material they use to pick a descriptor and a point score.

This is why a calm, capable-sounding answer can quietly cost you. If you say "I get by," the assessor has nothing to score, so they pick the 0-point descriptor. The activities you struggle with most are the ones where you should give the most detail, because those are where the points are.

The reliability test: the four words that decide your points

The most important rule in the whole assessment is the reliability test, and most claimants have never heard of it. The law says you can only be treated as able to do an activity if you can do it reliably, repeatedly, safely and in a reasonable time - and for the majority of the time, meaning more than half your days. If you can do something once, on a good day, with a long rest afterwards, that does not count as being able to do it.

Break it down and use each part deliberately when you answer:

• Reliably - to an acceptable standard, not a half-finished or unsafe attempt. "I can wash up, but I drop and break things and leave most of it" is not doing it reliably.
• Repeatedly - again and again as a job would need, not just once. "I can climb the stairs once in the morning, but I could not do it several times a day" matters here.
• Safely - without danger to yourself or others. If you get dizzy, lose balance, drop hot pans, or have seizures with no warning, the activity is not done safely even if you "manage" it.
• In a reasonable time - roughly the pace a workplace would expect. Taking three times as long as a colleague is not doing it in a reasonable time.
• The majority of the time - more than half your days. This is the part that protects people whose conditions fluctuate.

When the assessor asks "can you do X?", the honest answer is rarely a flat yes or no. The accurate answer is usually "not reliably, repeatedly and safely the majority of the time," followed by why. Saying those words out loud signals that you understand what is actually being tested.

A worked example: turning a real difficulty into a descriptor and points

Here is how a real-world difficulty becomes a score, so you can see why specific answers matter. Take the activity of remaining at a work station (standing and sitting). The descriptors run from 0 points (no real problem) up to 15 points (cannot stay at a work station for more than a few minutes combined). If the assessor asks "how long can you sit?" and you say "oh, a fair while," you may be scored at 0. But suppose the truth is this:

"I can sit for about 20 minutes before the pain in my lower back becomes severe. Then I have to stand or lie down for at least half an hour before I can sit again. By the afternoon I usually cannot manage even 20 minutes. This happens five or six days a week."

That answer points the assessor towards a much higher descriptor, because it shows you cannot remain at a work station for more than 30 minutes the majority of the time. The same approach works for every activity. For learning tasks, "I can't really concentrate" scores little; "I tried to follow a simple two-step recipe last week, forgot the second step halfway through and had to start again three times" describes a genuine functional limitation an assessor can score. Always move from the vague feeling to the concrete, repeatable, real example.

If your condition varies: good days and bad days

Fluctuating conditions - ME/CFS, mental health, MS, arthritis, long COVID and many others - are where claims are most often under-scored, because people instinctively describe an "average" day that exists only on paper. The assessment does not work on averages. It works on what you can do the majority of the time, so the bad days carry real weight if there are enough of them.

Give the assessor numbers. "Out of seven days, four or five are bad days where I cannot leave the house" is far stronger than "it varies." Describe a bad day in full, then explain how often it happens, then describe the cost of pushing through. If walking to the shops means you spend the next day in bed, that aftermath - sometimes called payback or boom and bust - is part of the picture and the assessor needs to hear it. Do not let a single good day define your whole claim. If you have your assessment on a comparatively good day, say so plainly: "Today is actually one of my better days, which is why I could get to the phone on time. Most days are not like this."

The Support Group, and substantial risk

There are two outcomes above "fit for work." Reaching 15 points puts you in the group with limited capability for work, but the more important target for many people is the Support Group (called LCWRA on Universal Credit). The Support Group pays more and carries no work-related requirements at all - no work-focused interviews, no work-related activity. For 2026/27 the Support Group element is around £145.90 a week, against roughly £95.55 a week for new claims in the work-related activity group, so the difference is significant. Whichever group you end up in, the rules on permitted work while on ESA still let you do a small amount of paid work without losing your benefit.

You can reach the Support Group in three ways: by meeting one of the Schedule 3 descriptors (the most severe level of a given activity), by scoring 15 points on a single activity, or through the substantial risk rule. That rule - Regulation 35 for ESA and Regulation 40 for Universal Credit - says that if being found fit for work or required to do work-related activity would put your or someone else's mental or physical health at substantial risk, you should be placed in the Support Group even if your individual descriptor points are lower. This matters most for serious mental health conditions, suicidal ideation, and unpredictable physical conditions such as uncontrolled seizures. If this could apply to you, say so clearly at the assessment, and ask your GP or specialist to spell it out in a letter using the words "substantial risk to health." Our guide to a supporting medical evidence letter for ESA explains what to ask your doctor to include.

Common mistakes that cost people points

• Answering for your best day. The single most common error. Describe your worst typical days and how often they occur.
• Being polite to a fault. Many people minimise their problems out of habit or pride. The assessor is not impressed by stoicism - they simply score what you tell them. Honesty is not complaining.
• Forgetting medication and side effects. Drowsiness, brain fog, nausea and tremor from medication all affect work-related function and should be mentioned for the relevant activities.
• Treating mental and physical health as separate. If you came in for a physical condition, do not skip the mental activities. Pain, fatigue and the strain of chronic illness commonly affect concentration, coping with change and dealing with people - and those points count towards the same 15.
• Describing the diagnosis, not the function. "I have severe arthritis" tells the assessor nothing scorable. "I cannot grip a kettle handle without dropping it" does.
• Letting silence fill in the gaps. On a phone assessment the assessor cannot see you wince, struggle to stand, or lose your train of thought. If something is happening, narrate it.

What to do if the decision is wrong

If the decision letter scores you too low or leaves you out of the Support Group, you are far from out of options, and a poor decision is common rather than unusual. You have one month from the date on the letter to ask for a Mandatory Reconsideration - a fresh look at the decision by a different decision maker. Use this to point to specific activities where you believe you were under-scored, quoting the reliability test and adding any evidence the original assessment ignored. Your own notes from the assessment, and any audio recording you arranged, are valuable here for showing where what you said did not make it into the report.

If the Mandatory Reconsideration does not change things, you can appeal to an independent First-tier Tribunal, which is separate from the DWP. Tribunals look at the same descriptors afresh and can be far more willing to hear how your conditions actually affect you day to day. Many people who were refused are awarded points or placed in the Support Group at this stage, so do not be discouraged by an initial knock-back. Keep copies of everything, stick to the activity-by-activity functional language, and keep the focus on what you cannot do reliably, repeatedly and safely the majority of the time.

One change worth knowing about

The Work Capability Assessment is currently under reform. The government has set out plans to change how the health element of Universal Credit is assessed, with the WCA in its present form due to be phased out over the coming years and replaced by a different process around the end of the decade. For now, the 17 activities, the 15-point threshold, the Support Group and the reliability test all still apply, and the advice above stands. If you are claiming now, prepare for the assessment as it works today, and keep an eye on GOV.UK for any changes that affect your claim before your review date.
