Wonder which engineer in Google came up with this rather dumb idea, but that is how it works, as far as I know.
To add further, I am not sure if .co.uk on your domain name would be given its due..Ever since websites like del.icio.us came up, the TLD has become more of convenience rather than pertaining to any particular geography..
If you're saying that some pages are cached I'm guessing it was either originally on a UK server or some other event has happened.
You do get a lot more weight being hosted in the country of origin so I would consider a transfer to a UK server anyway.
