As an update on this, and I guessing something that will help other UKREG customers...
The domain that I caught was already in someone elses UKREG account. I contacted FASTHOSTS Support who in lightening quick time confirmed this.
The following web page explains the process of getting it out of their a/c and into mine:

Kind of begs the question why leave expired domains in people's accounts and what would be the harm in admin deleting it from the previous owners account?
Bit of an a*se really as the domain isn't really that crash hot for the hassle of this. So, I'm just requesting name server change. Will be interesting come renewal time when it's still sat in the other person's account
