No it's not your eyesight, those 2 blobs were the only contact point, so conclusion being fixing method to blame I assume? Does the colour of the adhesive going a funny orange suggest something else is wrong in addition to a poor fixing method?

Is it likely that you could just remove the tiles and adhesive and just relay the floor, leaving the UFH "untouched" or would you suggest that the UFH & possibly the tile backer board are replaced too?

Sorry, I have a real problem with measurements tonight, should read 13mm/1.3cm for adhesive, 3mm/0.3cm for whatever got put over the UFH, so 16mm/1.6cm deep layer of adhesive in total. No idea of diameter, the tile has been relaid as a temporary measure so can no longer check.

SLC/adhesive (sorry don't know which was applied over the mat, have asked the builder but no surprises that he has yet to come back to me on that one) was applied over the UFH heating mat late afternoon, tilers arrived the following morning and completed the entire floor (including grouting) that day.

Well the fixing leaves a lot to be desired, but i would also say that the floor was laid too soon after the SLC went down. Certinly if it was laid at approx 30mm. I would of left it for a couple of days before tiling not the next morning.
