ASH,
I instruct on the R22 and R44 at Tatenhill Airfield, near Burton-on-Trent(also at Sheffield, but that's a bit further from you). I'd be happy to give you any information about anything to do with the PPL(H) course, here or elsewhere; just send me a PM.
(If you already know me, and you're who I think you might be, please pm me anyway, as I'd like to know how you're getting on. 
If you don't know me, ignore this bit)
