ESA50 vs UC50: The Differences (and Why It’s Now One WCA50)
If you have been sent a health questionnaire for your benefit claim, you may be wondering whether you have the ESA50 or the UC50, and whether it matters. Here is the plain-English answer: they were two versions of the same Work Capability Assessment questionnaire - one for Employment and Support Allowance (ESA), one for Universal Credit (UC) - and since late 2025 they have both been replaced by a single form, the WCA50.
They were always the same assessment
The ESA50 and the UC50 both asked about the same 17 Work Capability Assessment activities (10 physical, 7 mental and cognitive), used the same descriptors, and the same 15-point threshold. The only real reason there were two forms was that ESA and Universal Credit are two different benefits administered slightly differently.
The WCA50 replaced both (November 2025)
From 24 November 2025 the DWP replaced the separate ESA50 and UC50 with one combined WCA50 ("Capability for Work questionnaire"), covering both ESA and Universal Credit. The activities, descriptors and points are unchanged. If you were sent an older ESA50 or UC50 before the changeover, you can still complete and return it - you do not need to ask for the new form. The WCA50 can be downloaded from GOV.UK.
What still differs: benefit, terminology and money
Even with one form, it still matters which benefit you are claiming, because the outcome is described differently and paid differently:
| ESA | Universal Credit | |
|---|---|---|
| Old questionnaire | ESA50 | UC50 |
| Now | WCA50 (one combined form) | |
| Lower outcome | Work-Related Activity Group (WRAG) | Limited Capability for Work (LCW) |
| Higher outcome | Support Group | Limited Capability for Work and Work-Related Activity (LCWRA) |
| Higher-group pay | Support Group component, paid weekly | Health element, paid monthly (only at LCWRA) |
Which one applies to you?
ESA is a legacy benefit that is being wound down, so most people going through the WCA today are on Universal Credit. If you are unsure which you are on, check your award letters or your online account. When you build a report with ESAexpert you simply tell us whether you are on ESA or Universal Credit, and we word every answer and outcome to match - Support Group / WRAG for ESA, LCWRA / LCW for UC.
What does not change: how you win your claim
Whichever benefit and whatever the form is called, the way to succeed is the same: describe limitations rather than diagnoses, put them in a working-week context, apply the reliability test (reliably, repeatedly, safely, in reasonable time, on most days), and back each point with medical evidence.
Frequently Asked Questions
Is the UC50 the same as the ESA50?
They were two versions of the same Work Capability Assessment questionnaire - the ESA50 for Employment and Support Allowance and the UC50 for Universal Credit - with the same 17 activities, descriptors and 15-point threshold. Since 24 November 2025 both have been replaced by a single combined form, the WCA50, which covers ESA and Universal Credit.
Which form do I fill in now, ESA50 or UC50?
Neither is issued as a new form any more - the DWP now uses one combined WCA50 for both ESA and Universal Credit. If you were already sent an older ESA50 or UC50 before the changeover, you can still complete and return it; you do not need to request the new form.
Does it still matter whether I'm on ESA or Universal Credit?
Yes. The assessment is identical, but the outcome and money differ. On ESA it is the Support Group or Work-Related Activity Group, paid weekly. On Universal Credit it is LCWRA or LCW, with the health element paid monthly and only at LCWRA. So the wording of your report should match your benefit.
Are the WCA activities different for Universal Credit?
No. The 17 Work Capability Assessment activities, their descriptors and the 15-point threshold are exactly the same for ESA and Universal Credit. Only the name of the outcome groups and the way the money is paid differ between the two benefits.
