  • Water quality

    Your tap water will vary in taste and appearance depending on where you live in the region.

    Most of the water we supply is hard as it comes from groundwater which has percolated slowly through the soil and layers of rock.

    You can find out more about your water, its hardness and quality using our postcode checker.
