This course is an absolute must for anyone wanting to expand or start a new career in tiling. It's tough,draining and will push you mentally and physically but it is so worth it and the 1 day business side on Marketing, Sales and other techniques for running a business and getting customers is worth more than the 5 day course total on its own. That alone would put you ahead of the pack even if you didn't use tiling as your future career. Don't waste your time and money on any other glorified DIY course. You'll come away with the practical and business skills so it's a no-brainer.
