Welsh border supply, formerly part of Severn Trent. Variable between the Severn and Dee catchments.
What this means for your home
Your water is slightly hard — barely enough to notice.
You may see a faint film in the kettle over months rather than weeks. A softener is very hard to justify at this level, and scale protection on a new boiler is optional rather than sensible. Any filtration you buy here should be about taste and chlorine.
