How to Fill In the WCA50 Form (Formerly ESA50): Step by Step Guide
The WCA50 form (previously called ESA50 for ESA claimants, or UC50 for Universal Credit) is the questionnaire the DWP sends you as part of the Work Capability Assessment. How you fill in this form is critically important - it forms the basis of your entire assessment. While that assessment is being decided you are normally paid the ESA assessment-phase rate (first 13 weeks), so getting the form right is what moves you on to the higher group rate. This guide walks you through every section.

The WCA50 (also called the "Capability for Work questionnaire") is a detailed form that asks how your health conditions affect your ability to carry out work-related activities. It covers 17 separate activities - 10 physical and 7 mental or cognitive. The DWP uses your answers, along with any medical evidence, to decide whether you have Limited Capability for Work. The WCA50 replaced the old ESA50 and UC50 forms in November 2025 and is used for both ESA and Universal Credit claims.
Before you start: golden rules
Before picking up your pen, keep these principles in mind throughout:
- Think about work, not just daily life. Every answer should relate to how your conditions would affect you in a workplace - sitting at a desk for hours, dealing with colleagues, coping with deadlines and pressure, commuting.
- Describe your worst typical days. If bad days happen more than half the time, those ARE your typical days. Do not describe your best days.
- Be specific. Instead of "I struggle with sitting," write "I cannot remain seated at a work station for more than 25-30 minutes before severe pain in my lower back forces me to stand up or lie down."
- Mention medication side effects. Drowsiness, brain fog, nausea, dizziness - these all affect your ability to work and count towards your score.
- Do not leave any box blank. Even if you think an activity does not apply to you, write something. You might be scoring points you do not realise.
Section by section guide
Personal details section
This is straightforward - your name, address, NI number, and GP details. Make sure your GP details are correct as the DWP may request medical evidence from them.
Your health conditions
List EVERY condition, diagnosis, and symptom you have. Do not just list your "main" condition. Include mental health conditions, pain conditions, side effects that have become conditions in their own right, and anything that affects your ability to function in a workplace. Each condition can contribute points across multiple activities.
Your medication
List every medication with dosage and frequency. Note the side effects you experience too. If your painkillers make you drowsy, if your antidepressants cause brain fog, if your blood pressure tablets make you dizzy - write it all down. These side effects directly affect your WCA score.
The 17 activity questions
The form then asks about each of the 17 WCA activities. For each one, you will be asked whether you can do the activity, and if not, to describe your difficulties. Here is how to approach each answer:
Physical activities (1-10): These cover mobilising, standing and sitting, reaching, picking up objects, manual dexterity, communication, understanding communication, navigation, continence, and consciousness. For each one, think about whether you could do this in a workplace, repeatedly, for 8 hours, 5 days a week.
Mental/cognitive activities (11-17): These cover learning tasks, awareness of hazards, initiating and completing personal actions, coping with change, getting about, social engagement, and appropriateness of behaviour. Many people with mental health conditions underscore themselves here because they focus on physical limitations. Depression, anxiety, PTSD, ADHD, and autism can all score highly across these 7 activities.
Key phrases to use
The WCA has specific legal terminology. Using these phrases in your answers helps the assessor match your description to the correct descriptors:
- "The majority of the time" (meaning more than 50% of the time)
- "Significant discomfort or exhaustion"
- "I cannot do this reliably" (meaning safely, repeatedly, to an acceptable standard)
- "I need supervision/prompting/physical assistance"
- "This would not be possible in a workplace environment"
How long should your answers be?
Each answer should be at least 200-350 words if possible. Use additional sheets if the boxes on the form are too small - just make sure you clearly label which question each answer relates to. Short, vague answers like "I find this difficult" will score zero points. Detailed, specific answers with examples, frequencies, and consequences are what score points.
Sending the form
Keep a copy of everything before sending. Send by recorded delivery if possible so you have proof of posting. Include any supporting evidence - GP letters, consultant reports, fit notes, prescription records. It is worth asking your GP for a supporting medical evidence letter for ESA that spells out how your conditions affect you. The more evidence you provide at this stage, the better.
You must return the form within the deadline (usually 4 weeks). If you need more time, call the DWP and ask for an extension before the deadline passes.

Frequently Asked Questions
How do I fill in the WCA50 (ESA50) form correctly?
Answer every question by describing how your health conditions affect you in a workplace, not just at home. Base your answers on your worst typical days - if bad days happen more than half the time, those are your typical days. Be specific about distances, times and consequences, and never leave a box blank, even if you think an activity does not apply.
How long do I have to return the WCA50 form?
You usually have four weeks from the date on the form to complete and return it. If you need more time, call the DWP and ask for an extension before the deadline passes, as they will usually grant one. Returning the form late without an extension can lead to your claim being closed.
What 17 activities does the WCA50 form ask about?
The form covers 17 activities in total - 10 physical and 7 mental or cognitive. The physical ones include mobilising, standing and sitting, reaching, manual dexterity and continence. The mental and cognitive ones include learning tasks, coping with change, social engagement and behaving appropriately. You score points across all 17, and physical and mental points are added together.
Should I describe my good days or bad days on the form?
Describe your worst typical days, not your best. The Work Capability Assessment looks at whether you can carry out an activity reliably, repeatedly, safely and in a reasonable time the majority of the time - meaning more than 50% of the time. If you can only manage an activity on a good day, you cannot do it reliably, and you should explain that clearly.
Should I mention my medication and its side effects?
Yes. List every medication with its dosage and frequency, and describe the side effects you experience. Drowsiness, brain fog, nausea and dizziness all affect your ability to work and can count towards your score across several activities. Side effects are often overlooked, yet they can make the difference between scoring points and scoring zero.
Can I include extra sheets and evidence with the form?
Yes. If the boxes are too small, use additional sheets and clearly label which question each answer relates to. Include any supporting evidence you have, such as GP letters, consultant reports, fit notes and prescription records. Keep a copy of everything and, if posting, send it by recorded delivery so you have proof.
What happens after I send the WCA50 form back?
The DWP uses your answers and evidence to arrange a Work Capability Assessment, which is usually carried out by phone or as a paper-based assessment from your form alone. A decision maker then decides whether you have Limited Capability for Work. If you disagree with the outcome, you can ask for a Mandatory Reconsideration and then appeal to a First-tier Tribunal.
