Meant to add the Phone Number for ALL UK passport enquiries: It is 0870-521-0410 (calls charged at National Rates).

Apparently the Glasgow Office deals with applications from the whole of Scotland ... fair enough! Strangely, though ... as I've only just discovered ... it also handles all Postal Applications from - wait for it - each of the London Boroughs!! Nonetheless, this rather daft way of working DOES, at least, kinda back-up what I've mentioned in my immediate previous post above.
