If we are claiming Universal Credit (UC) and have (or may have) contracted coronavirus and are self-isolating, we’re not expected to search for work. Nor are we expected to be available for work, the way UC claimants usually are. We must contact our Work Coach as soon as possible to let them know, either through the online journal or the UC helpline.
Advice is changing all the time and the period of self-isolation this covers could vary. Same applies if we usually search for work at a public place, like a library, which are all currently shut down.
