As Pilot DAR says, there are many FTOs in Western Canada, all the way from Calgary to Vancouver Island, that offer "mountain checkouts" - there is no actual rating.
I can recommend doing one of these checkouts. Western Canada is easy to get to, the flying will be much cheaper than in the UK and of course, there is no language problem.
For mountain flying somewhat further away, see this thread:
