Water in Brighton and Hove
- Brighton has very hard water drawn from the South Downs chalk aquifer, typically 280 to 330 mg/l CaCO₃.
- Essentially all of Brighton's water comes from that single chalk aquifer beneath the Downs, making the supply unusually uniform across the city.
- The city's dense stock of Victorian and Regency conversions means many properties are flats with no drain access near the stopcock, ruling out conventional softeners and driving demand towards inhibitors and point-of-use filtration.
- Brighton's large independent café and restaurant sector makes commercial scale protection a significant local trade.
- Coastal properties here contend with hard water and salt-laden air together, which is hard on external plumbing and fittings in a way inland hard-water areas do not see.
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.
