Pilates classes in the north

Hi all
I was wondering if anyone knew of any Pilates training courses up north. I live in Newton Le Willows near Warrington, Liverpool and Manchesterand went to a class recently and loved it. I also have the Marie Windsor Pilates DVDs and they are great. I would be interested to see if anyone knows of courses around here. I will also do a google search.
Thanks
