There isn't a -200 sim in the UK as far as I am aware. There is one in Dublin. At the beginning of this year it belonged to Air Lingus - I don't know if this is the same one mentioned above - perhaps under different management?
Your query does beg the question though - why would someone want to practice on a 732 sim? If it is for a sim assessment, there is only one company in the UK flying the 732 and they do their sim assessments on a 727 sim anyway...
