Why don't you start one in your area.
BTW some of them are:
SWUGoCE Birmingham Jeremy Ferguson SWUG London Nick York SWUGoSE Bournemouth Kevin Clouden SWUG Manchester Kevin Clouden
There are SolidWorks user groups in the UK. A couple of them are inactive right now, but steps are being taken to address that. 2014 will be a big year for international groups.
Check www.swugn.org and look at the "About SWUGN" page, then send an email to Kevin Clouden. He can help you find a group, or perhaps convince you to take the lead on one of the inactive groups :)
