Water hardness

When water falls as rain, it's "soft" and free of minerals.

It picks up naturally occurring minerals, such as calcium and magnesium, as it passes through rock, sand and soil. This causes the water to become ‘hard.’

All the water we supply is ‘hard’ together with more than 60% of homes in the UK.
