..........letter inviting you to a redundancy hearing, discussions, follow up meeting to discuss ideas alternative to redundancy that you may come up with (such as transfer to another branch if they have one), and then a follow up meeting to confirm redundancy.
My old employer did follow the above process, SE Boy. This took 1 month, so I effectively had an extra months "employment" as a result and an extra months wages. I recall we had several meetings. I was also allowed to use the company phones and computers / internet and printers to help me find a new job and was allowed "time off" for interviews - not sure if that was obligatory or not.

Fortunately for me I found a new job just some 7 weeks after my last day at work and it came with a pay rise. Hopefully you will land on your feet the same way.
