Your work capability questionnaire
This covers the Universal Credit health element and New Style ESA — they use the same assessment, so this one form serves both. It takes around 45–60 minutes.
What we're aiming for: there are two possible outcomes. "Limited capability for work" (LCW) means you don't have to look for work. "Limited capability for work and work-related activity" (LCWRA) means that plus a substantial extra monthly payment and no requirement to attend appointments or prepare for work. LCWRA is what we're aiming at, and it turns on how you describe your worst days.
The rule that decides most claims: can you do it reliably — safely, to a decent standard, as often as needed, and in a reasonable time? Doing something once, slowly, in pain, and then needing to recover is not being able to do it. Answer for how you are most of the time, not on your best day.
Please read if any of this applies to you: if working or preparing for work would put your health or safety — or anyone else's — at substantial risk, that alone can qualify you for LCWRA, regardless of points. This matters especially with severe mental health conditions, suicidal thoughts, epilepsy, or unpredictable collapses. There's a question about this near the end. Please answer it honestly, however hard it is.
