Ok, have just spoken to Doreen, who was very patient with my questions and was happy to put my mind at rest.
All they require is that you fill the registration page and submit it. Don't complete the whole application again. I indicated that I felt uneasy that my place in the process might be effected or worst still I might be lost 'in the system' . She was able to immediately pull up my application on file and reassure me of my place in the scheme of things. She even went as far as to say that I could even be looking at an April / May start for KX. I certainly won't hold her to that as we've seen how timescales change, but it's certainly not doom and gloom.
And before anyone asks.........no, I didn't ask about Bedford ! ??????
