Have him replace them.

yup. And, get a new saw blade before he does and cuts new ones.

Absolutely replace them. That just looks sloppy, and you are the one who gets to look at it every day, not the fitter.

Thanks guys - will speak to them this evening.

Personally, I would expect them to be replaced. My first tiling project was with porcelain tile, and I concur that they can be difficult to cut. A wet saw with a new sharp diamond blade is important. Similarly new high quality diamond drill bits are necessary to drill holes.

In the last picture he should have used special trim pieces that are bullnosed, or he should have put the cut side at the grout joint, though with all those chips that still would not have looked good. Was this a professional tile setter?
