Dŵr Cymru Welsh Water water hardness
Ranges from soft to hard across the supply area.
Dŵr Cymru Welsh Water supplies water ranging from soft to hard across its area, so the figure for your own postcode is worth checking.
Mostly soft upland reservoir water, but the range is wide — parts of south and east Wales draw from harder sources. Worth checking rather than assuming.
What this means for your home
You have soft water — there is no limescale problem to fix.
A water softener would be money spent on a problem you do not have, and anyone trying to sell you one here is worth questioning. If you want to improve your water it will be about taste, chlorine or older pipework, not hardness. Soft water is also slightly more inclined to dissolve metals from old plumbing, which is a different reason to filter drinking water.
