How can I determine if I have hard water?

 Any of the symptoms below can signify the presence of hard water:

  • Furred up kettle
  • You have unattractive white/brown stains on sinks, baths, toilet bowls and around the foundation of taps
  • Your showerheads are clogged
  • Soaps and detergents resist foaming
  • You have spots on your dishes or shower doors

Contact your local supplier’s customer services for information on water hardness in your area, or check local water hardness online by postal code.

 If you are on a municipal water system, contact the supplier for information concerning the level of hardness of the water they deliver. If you have a private water supply, you can have the water tested for hardness.


Limescale damage around the house is a bigger problem than you might have thought. For example 1 in 10 irons sold are returned within 1 year. 65% of these are due to limescale damage.
