Sorry if i wasn`t clear. I removed face plates and tiled behind. I was pleased with how they looked, tidy and professional. No edges showed, the spark was there as i tiled behind and he screwed in place? I wasn`t sure exactly what was wrong, the builder who phoned me was also unclear. My understanding was that you should tile behind face plates, but it seems i was picked up for tiling to far behind and that there is some rule on how far behind face plate you should tile?
Hope this is clearer.
