Yes, TigerHelicopters use Gloucester ATC to do the test for the IR. They use their own A109 for this, so no worries about having to beg another operator for a machine.
I think that the A109 twin IR sim, run by Don MacDonald, is very popular and the pass rate is amazingly high.
And rumour has it that they've just bought 2 more A109s to cope with the demand.
There's a lot of info on their website.
