What it means for your home

Moderately hard water leaves some scale, but slowly. The kettle and shower head need descaling now and then, and that is usually all.

The right detergent dose and a correctly set dishwasher are enough for most homes. A softener is rarely needed.

How often to descale

Common questions

Is hard water bad for you?

No. Hard water carries calcium and magnesium, minerals the body uses. Whether tap water is safe depends on germs and pollutants, which water companies test for, not on hardness.

Do I need a water softener in Kenilworth?

The water company's figure for Kenilworth is 160 mg/L (11.2 °Clark), which is moderately hard water. Usually not straight away. Set the dishwasher, dose detergent for your band and descale regularly. Get quotes for a softener only if scale is clearly damaging your boiler or appliances.

How do I find the value for my address?

Use your water company's postcode checker. Hardness can differ between districts, so check your own postcode, or test with strips or a drop test.
