That document by Hooper which Nellie linked to above gives October 2004 as the date. I will look for corroborative evidence.
This 2006 document has an intro from Aylward saying it was a year since the centre became 'fully operational', so 2004 for a less than fully operational launch sounds about right: https://issuu.com/maxhead/docs/unum_cardiff_newsletter_issue_2
