and eventually in a boiler heat exchanger. A softener plumbed into the rising main treats the water once, at the point it enters the building, and everything downstream stops furring up.

Water softener installation in London: what the price includes

  • 01
    We test before we sell you anything

    Hardness is measured at your tap, not assumed from the postcode. London typically runs 280–320 ppm from the chalk aquifer, which is firmly in softener territory. If your supply turns out softer than expected, we will say so rather than fit one anyway.

  • 02
    Plumbed on the rising main, with a bypass

    The unit goes in after the stopcock and before the first tee, with a hard-water drinking tap kept separate so the kitchen cold still tastes of what you are used to. A bypass valve means a fault never leaves you without water.

  • 03
    Block salt or tablet, sized to the household

    A two-person flat and a six-person house need different regeneration cycles. Oversizing wastes salt and water; undersizing leaks hardness through at peak demand. Sizing is part of the survey.

  • 04
    Drain and discharge done properly

    Regeneration brine needs an air gap to the waste to satisfy the Water Regulations. Done wrong it is a backflow risk and a failed inspection, it is one of the most common faults we find on someone else's installation.

  • 05
    What it actually saves

    Kettles and shower screens are the visible part. The real number is on the boiler: scale on a heat exchanger measurably cuts efficiency and is a leading cause of lockout faults in hard-water London.

Local conditions we work around

This is a service that genuinely pays for itself in London. At 280 to 320 ppm off the chalk, scale is shortening the life of your boiler, cylinder, shower valves and every appliance that heats water, and a correctly sized softener stops that happening rather than treating it afterwards. It needs a drain connection, a power supply and space near the rising main, plus a hard-water drinking tap kept unsoftened. In a flat it also needs freeholder consent, which is worth checking first.

Water softener installation in London, your questions

Do I need a water softener in London?
In London, almost certainly worth it, the supply runs 280 to 320 ppm and the scale damage is cumulative.
Can I still drink the water?
Softened water is safe for most people but higher in sodium, so we keep one hard-water tap at the kitchen sink for drinking and cooking. That is the standard installation, not an upgrade.
How much salt does it use?
A typical family home gets through roughly one 8 kg block a month, so about £60 to £90 a year. Metered units regenerate on volume rather than a timer, which is why we fit those.
Will it damage my old pipework?
It will not corrode sound pipework. It does gradually dissolve existing scale, which in very old systems can unmask a pinhole the scale was plugging, we check the condition of the pipework before commissioning for exactly this reason.
Where does it go?
Under the kitchen sink most often, or in a garage or utility next to the incoming main. It needs a drain within reach and a socket if it is an electric metered unit.
