It does depend on how much build up of limescale you already have in your home. However, typically:
 
6 weeks – limescale will have been removed from your kettle.
6 months – limescale will have disappeared from your heat exchanger.
and up to 2 years limescale will have gone from the rest of the pipework around your home.
