I've sent you a PM but I did CPL and IR with them, finishing May this year and was very happy with them. Aircraft were fine (I had no tech issues) Instructors great, Management great, Atmosphere great. They used to let IR studes practise for free on the FNPT1, which was a priceless perk and one of the things that swung it for me initialy.
My CPL and IR instructors have both got jobs flying bigger things so my experience there isn't valid anymore.
Downside is the transit to Cranfield for the test sectors which can get expensive at 20 mins each way, but it's all practise and that sort of flying is loaded at the end of the course anyway.
It manages to strike that balance between professional and informal and friendly very well I think. Definitely worth a look if you live in that area.
Good luck
