Scale inhibitor installers in Cambridge
Cambridge has hard water, and a scale inhibitor on the boiler is the cheapest useful protection against it. Here is what one does, what it does not, and who can fit it.

Water in Cambridge
- Cambridge has some of the hardest water in the UK, drawn entirely from chalk boreholes and commonly above 300 mg/l CaCO₃.
- Cambridge Water supplies a compact area with unusually little variation, so unlike most places the local figure really does apply across the city.
- The chalk aquifer beneath Cambridge is under significant abstraction pressure, and water resources are an active local issue alongside the city's rapid growth.
- The University and the surrounding research and biotech sector generate substantial demand for laboratory-grade purified water, which is a specialist commercial market barely present in most comparable cities.
- Limescale is severe enough in Cambridge that scale protection is effectively standard practice at boiler installation.
You have hard water — scale protection is worth having.
The World Health Organization notes that water at 200 mg/l or above will produce scale, and that is where this band begins. At this level limescale is a recurring cost rather than an occasional nuisance, and many boiler manufacturers require scale protection to keep the warranty valid. A softener is worth costing out properly.
