When I went there a few months back I approached the people just to the left as you turn off the main road and was quoted £25 per hour for an instructor.
There are a few there, ask them all.
What are you training in? I found I had to get transport cat C oF A to allow it to be used for training but I think the new EASA covers anything. No doubt someone will be along to put you right if that isnt actually the case. Just had to re check the insurance covered PPL training and solo flights as some companies dont.
Good luck anyway
