I have heard only good things about Chase Tiling in Cannock Staffordshire. Easy to get to from the M6 and carry out Only Wall and Floor Tiling Courses, which means they are specialists, they don't run any other course type, you usually find this type of tiling course is the most rewarding. These also don't do a hard push on tiling tools or other gear, they just let you know what you need and the cheapest place to get them
I'd pop over to see the centre, or at least give them a call.
