What should I put between window cill and internal block wall.

At the moment when I look at the window cill internally, I see the cill (with window on top) and DPC right up the back of it and then a gap (cavity with some ecobeads) and then inner wall. I am told to pull the DPC right up to touch the bottom of window and push down beads and ram some kingspan insulation in to keep everything in place. is that ok ?
