TheBoyLedgend, you are right we do not have chapter 11 style protection as they do in the US. What the poster may be referring to is a moritorium that is put in place over the company once a "notification of intention to appoint an administrator" is filed with the courts.
Companies house would not yet show anything as the NOI is a court document, the first CH document you would see would be a notification of the appointment of an administrator circa 10 days after any appointment takes place. (All of this is assuming Mongoose is a limited company of course?! I havent checked)
I will have a word with a few colleagues and see if anything has been heard.
