Yes, and no :-). It is best practice to add an extra earth wire (suitably sleeved in yellow/green) from the backbox earth point to the metal face earth point of the dimmer. However the regs don't actually insist on it IF (and only if) one of the faceplate mounting screw lugs is fixed (not adjustable/sliding)
