As an opening line I thoroughly recommend JD Aviation.
I did my CPL and IR back with John a few years ago. As a disclaimer i also went on to be an instructor for him and if it wasn't for the demands of my companies rostering department I would happily still do work for John if he would have me.
John is an excellent instructor who will not tell you how good you are just to take your money. He wants you to be the best and he takes immense pride in the quality of his students. He will give his time and effort to get you through your training not just with a pass but with a knowledge to last you your entire career. He also teaches something that can sometimes be looked over and that is the biggest thing of all. Airmanship.
I work for a 757 operator at Manchester as a Captain and there are many of his ex students both at my airline and other operators based at Manchester.
My recommendation is give him a call and go and see him.
