You might try the EBU website:www.ebu.co.uk
There are plenty of links to the information you're looking for.
You can download blank convention cards, or a completed Standard ACOL or modern ACOL card. And there is a link to the "Orange Book", a handbook of EBU directives and permitted conventions.
(You didn't say where in the UK;
the Scottish Bridge Union - www.sbu.dircon.co.uk
the Welsh Bridge Union - www.wbu.org.uk
I don't have a link for Northern Ireland, if there is one.)
As far as opening a 12-14 1NT with 17 hcp - I would have to determine whether or not it was deliberate (a psych) or not (a misbid). In either case, it is legal - though if it happens often, there may be repercussions - You can check out the Orange Book (Sec. 6.2)
