I've got a Hamilton thermostatic mixer shower bought from Wickes (who no longer sell) a while back.
I need to replace the cartridge, but I dont know where to go from here? I cant see any grub screw that I need to remove.

I wish you luck with valve been from Wickes.
We always use someone like Bristan or Mira for brassware way more chance of spares been easily available.
