OK update for anyone intending on doing it. It's literally a two second job!

Firstly remove the existing fog light surrounds. To do so, there's two little clips on the centre of the car side, pop them out the basically pull the covers out.

Secondly, put the covers on! They clip back in, the same as the surrounds came out. No need to remove you fog lights either, they can stay right where they are. Small point i found however, when your clipping the covers in, you will find a clip on top of the cover. There's also a clip inside the bumper itself. Make sure the clip on the bumper goes under the cover not above it. Otherwise you will find you have a gap between the top of the foglight cover and the bumper.
