as mentioned above but use square chrome tile trim run at sill height if needed cut lip off back and stick on top of sill tiles against window frame (not all of lip just enough to go between sill tile and frame hope you understand):8:

Also if you intend to tile the cill then remove the wood and line with plaster board..the wood will expand and contract thus cracking the grout on the face edge..

looking at the job , the original cill is still there under the board you can see , it has just had the bullnose cutoff , i was intending using hardiebacker to line the reveal , so i would have a lyer of 6 mm hardiebacker over the original cill , i now reckon the marks on the upvc frame can be dealt with ok , so thats one issue gone , the tiles appear to have a 3 mm spacing so i will set them off the worktop surface by the 3mm a spacer will give me 🙂
