Northumbrian Water water hardness
Ranges from soft to slightly hard across the supply area.
Northumbrian Water supplies water ranging from soft to slightly hard across its area, so the figure for your own postcode is worth checking.
Soft upland reservoir water. Limescale is largely a non-issue; the filtration questions here are about taste, chlorine and lead pipework instead.
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.
