I've had really good feedback about both UK Tiling Courses and North East Tiling Training Courses recently. These two training centre's promise competitive prices and only high-quality tiling training courses but what's worth moret han that is the fact that these training centre's do NOT run any other course types meaning they are specialists in tiling training courses.
Other training centre's can be busy and have more than a few course types which means your teacher could just be paid on a daily rate and is just a
tiler themselves and not a real teacher! - Check when calling! Courses have been known to be slightly less smooth with this type of setup.
