Water in Surrey
- Surrey sits on the North Downs chalk and has very hard water, typically 280 to 340 mg/l CaCO₃.
- SES Water — formerly Sutton and East Surrey Water — supplies much of the county and reports some of the highest hardness figures published by any UK company.
- Surrey has among the highest rates of domestic water softener ownership in the country, and installers here fit them as core business rather than as an occasional extra.
- Reverse osmosis is more commonly requested in Surrey than in most counties, partly because very hard water makes the difference in taste from an RO tap especially noticeable.
- The county's large detached housing stock generally has the space, drain access and stopcock accessibility that make softener installation straightforward — the opposite of inner London flats a few miles away.
You have very hard water — among the hardest in the UK.
Limescale will be a constant in your home and a real cost in appliance life. A water softener is genuinely worth the investment here and most households who fit one notice the difference within days. At the very least, protect the boiler.
