A little bird told me somewhere that you should book it in for full oil change after about a thousand miles...something to do with metal deposits being in the oil from build?
It must be an ancient, old skool little bird who told you that - unless yours came without an oil filter!

Anyone any thoughts on this? Would it be as well to book an initial UK service at the same time to make sure everything is as it should be?
No "initial" service is required, but contact VWUK ASAP to get your car registered on their system, so that you can be notified of any official updates, register your warranty, and get your 12 months VW Assist.
Oh, and make sure it is NOT on LongLife servicing.
