I think that's my fault, I tried to explain that what I do is snap cut them into 4 bits now as they snap really easy on the score line then lay them as individual 200mm tiles. The problem with matching the pre-scored grout joints is that in an ideal world, especially with UFH, a 1mm joint is not wide enough and if there was ever a problem that's the first thing that will get pulled. That being said, sure it will be fine and a cracking job done.
