Yes, the CEP scheme is running continually with no closing date in site, although obviously it will close at some point.
Phone number is 0870 60 80 747 and there's a bit on the BA recruitment website

This forum is excellent for preperation for the 2 days of selection. Just scan through the last 10 days and you'll get links to info on the aptitude tests and advice on the other selection methods used.

Good luck to him anyway, it's a long journey which I hope will be worth every mile!
PS Anyone at Final Board on the 8th March?
