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. This guide walks you through every section.

What is the WCA50 form?

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. Crucially, note the side effects you experience. 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. 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.
