I have flown with Rotorvation for the past seven years since gaining my PPL(H). Additionally I completed my conversion onto their R44 Astro. There is plenty of information on the website at
http://www.rotorvation.com (although I have just tried this and it doesn't seem to be working at the mo - not sure why) but my recommendation would be to phone Richard Woods (tel: 01322 865992) the owner, and arrange to go along, meet him and one of the instructors, and have a chat and a look.
Richard's R22 and R44 are immaculate and his instructors, as mentioned above, are highly experienced freelancers with thousands of hours to their names. The location is an unusual one and quite a confined area, with easy access to Rochester, Biggin, Redhill and the London heli-routes.
I should add that I have no commercial interest in the company, I merely self-fly-hire there (I also hire elsewhere) and have enjoyed doing so. Best of luck with your training, wherever you decide to learn.
