Selsey sits at the southernmost tip of the Manhood Peninsula — a peninsula that projects into the English Channel and shares one of the hardest water supplies in West Sussex. For a relatively small coastal town, the combination of very hard water and a marine environment creates a particularly challenging set of conditions for home maintenance.

Water hardness in Selsey

Selsey and the surrounding Manhood Peninsula draw from the South Downs chalk aquifer, producing water that typically registers around 306–312ppm — classified as very hard and significantly above the national average.

Why Selsey is a particularly good case for a water softener

Selsey has a distinctive property profile — a significant proportion of retirement and second home properties, holiday lets and coastal homes that face both the internal challenge of very hard water and the external challenge of salt air from the sea. This combination accelerates wear on plumbing and appliances faster than almost anywhere else in Sussex.

For retired homeowners — a significant demographic in Selsey — the practical benefits of soft water are particularly valuable: less physical effort cleaning bathrooms and surfaces, lower ongoing maintenance costs, and the peace of mind that the boiler and appliances are protected for the longer term.

For holiday let and second home owners, a water softener reduces the maintenance burden between stays and protects the property's appliances from the accelerated wear that comes with a combination of high seasonal usage and very hard water.
