Called this number this AM, got to a very helpful person, asked could she give me my status, as online portal just says "completed", she said a letter was issued on 11/11/26 (which was the day my status changed from in Progress to completed), went on to detail what letter said, which is I've been accepted!+44 191 203 7010
She also detailed I would receive a bill next April/May etc etc, I know the routine from there
So I'm in! Might be worthwhile if you haven't received a letter, and status shows 'Completed' that completed = accepted (and not rejected)
