I'd just like to tag on a request for info/experiences/recommendations/or otherwise on the theory (just the IR, not the ATPL or CPL) side of things.
According to the (UK) CAA list of approved training organisations there are three, namely Atlantic Flight Training, Cranfield Aviation Training School and Ground Training Services.
If anyone's got personal experience of any of them for the IR(H) theory I'd appreciate hearing about it...
Cheers.
