Yeah they do.
I've read somewhere it is £7.5k for a rated FO, which seems rather high and makes you wonder if it is a means to tie people to the company for a few years and discourage them from leaving (having said that I've no idea what other companies do these days and it might be standard practice).
For a non rated FO it is still £25k+ I believe, but might be wrong.
As far as I'm aware there is no bond for internally upgraded FO's.
