Mandatory reconsideration requests, sanction appeals, evidence for a work capability assessment or a change of circumstances - write it here and we'll post it the same working day.
Most Universal Credit business is done through your online journal, but some things still need to go in writing by post - particularly formal mandatory reconsideration requests, appeal evidence, and correspondence when your online account is suspended or you've been asked to provide documents your work coach can't accept digitally.
