A Parliamentary written question, answered on 7th June, about the restarting of Face to Face Work Capability Assessments:

https://questions-statements.parliam...021-05-25/7143
Following their suspension in March 2020 due to the COVID-19 pandemic, from 17 May 2021 we have resumed face-to-face Work Capability Assessments for Employment and Support Allowance claimants, and for Universal Credit claimants who have reported a disability or health condition that affects their ability to work. Initially they will only be for those who we are unable to assess by other channels, and are taking place alongside existing paper-based assessments, telephone assessments and a small number of video assessments where suitable.
So currently you will only be asked to a F2F WCA if for some reason you can't be assessed on paper or by phone.
