Hiya @wrighty and welcome to the forum. (A long time ago). This thread needs an answer as it's getting attention. So if I were in Nottingham, then I'd travel the A50 daily and go to www.TradeTeacher.co.uk (click tiling courses). Can do a short course and stop local for a week maybe. Consider the fuel cost and accommodation and things, traveling north would get you UK Pro Tiling Training - https://www.tilersforums.com/threads/uk-pro-tiling-training.81726/ who are awesome. @UKTT Darren and Tracey (his wife) both awesome. After-course support and is brilliant.
If you travel west you've got @Expert Tiling Courses UK who are in Newport. Good lads they seem and I think we'll be using them for the midlands training centre for the forum ongoing.
Go south you've got www.AbleSkills.co.uk who are also awesome. They do loads of courses and have bought their own accommodation which is well priced I think if I remember rightly.
It's an area of the forum I'll be working on hopefully with the support of all the training centres we're recommending out of experience and in knowing tilers, plumbers and electricians do end up on the forums for years who trained with these companies years ago.
