Does anyone have any ideas how (from a script) I can determine whether a
date is a (UK) bank holiday?

Where in the UK?

England+Wales, Scotland and NI have different dates - http://www.direct.gov.uk/en/Governmentcitizensandrights/LivingintheUK/DG_073741

Worse than that, different places in Scotland have additional holidays - the first reference to that I could find was at http://www.sjib.org.uk/page.php?pageid=92
