Lake District and Pennine reservoir water. Manchester and Liverpool are soft-water cities, which is why softener demand there is a fraction of the South East's — but taste, chlorine and old lead pipework still drive plenty of filter installations.
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.
