Like most of the capital, Wandsworth is supplied by Thames Water from sources that give London some of the hardest mains water in the country. Here are the four most common and costly problems it causes.
Limescale accumulates on taps, shower heads, tiles and kettles across Wandsworth homes, requiring constant descaling and leaving fixtures stained within weeks if the water isn’t treated.
Limescale narrows the internal bore of pipework over time, especially in hot water pipes where scale build-up is accelerated by temperature — reducing flow and efficiency.
Washing machines, dishwashers, electric showers and combi boilers in Wandsworth’s hard-water postcodes suffer accelerated wear, increasing energy use and causing early component failure.
Hard water reacts with soap and shampoo to form scum rather than lather. Many Wandsworth residents notice drier skin and duller hair directly linked to mineral-rich mains water.
A complete installation — from system selection through to full commissioning and optimisation — carried out in a single visit at a fixed price.
Your plumber assesses existing pipework, identifies the mains inlet, and determines the best installation position — typically under the kitchen sink, utility room, garage or basement, common across Wandsworth's mix of flats and terraced houses.
For supply and install bookings, we recommend the right capacity and regeneration type for your property size and Wandsworth's water hardness. Brand-independent advice from leading manufacturers.
The softener is installed on the mains inlet and connected to drain for regeneration, with a bypass valve fitted as standard. All connections meet current water regulations.
The unit is commissioned to Wandsworth's local water hardness settings, the regeneration schedule configured, and a full test cycle run before handover.
Four measurable improvements from the day it’s commissioned — all compounding over time as limescale is progressively removed.
Softened water deposits no new limescale, and existing scale dissolves progressively — restoring flow and protecting older pipework common in Battersea and Wandsworth Town properties.
Washing machines, dishwashers, showers and boilers all last longer on softened water — most manufacturers recommend it in hard water areas like Wandsworth.
Softened water lathers better and leaves no scum or staining — noticeable from first use, particularly for showering and washing up.
Descaling products, replacement showerheads and early appliance replacement are recurring costs in Wandsworth's hard water postcodes — a softener removes the cause, not just the symptoms.
Cost depends on whether you supply the unit, pipework complexity, installation location and system size. All prices confirmed before we attend — no call-out charge.

The same fixed pricing applies whether you're in SW11 Battersea or SW15 Putney — no zone uplift, no call-out charge, no extras added after the fact.
We supply Harvey, Kinetico, BWT and other leading systems, recommending based on your Wandsworth property and water hardness — not brand preference.
All water softener installation work in Wandsworth carries our 12-month guarantee, issued in writing on the day of installation.

“We’d been through three electric showers in eight years — all failed due to limescale on the elements. Had a water softener installed in the utility room and the current shower is still running perfectly two years later. Very neat installation, minimal ongoing salt cost.”
“Victorian terrace in Battersea with genuinely awful limescale on every tap and the shower screen constantly needing scrubbing. Supply and install of a mid-tier system, and within a few weeks everything looked clean again.”
“Already had a softener bought online, just needed it fitted properly under the sink in our Putney flat. Explained the bypass and salt settings clearly and the job was done in under three hours.”
Install-only (customer-supplied unit) starts from £200. Supply and install starts from £650 for an entry-tier unit, £950 for a mid-tier unit, and from £1,400 for a premium system. Annual servicing starts from £99. All prices confirmed before work begins.
Yes. Wandsworth is supplied by Thames Water at 250–300 mg/l (as CaCO₃), classified as hard to very hard — consistent with most of the capital.
Yes. Our engineers are experienced with discreet, low-impact installations that respect original pipework and fittings in Wandsworth's older housing stock.
In Wandsworth's hard water areas, a typical 3–4 bedroom household uses approximately 2.5 to 4 kg of salt per week. Most units have a 15–25 kg capacity, meaning roughly monthly topping up. We configure the regeneration schedule for your usage during commissioning.
Yes, for most adults. Current guidelines recommend against using softened water for babies' formula or by those on a medically supervised low-sodium diet — so we fit a bypass to the cold kitchen tap as standard, giving access to unsoftened mains water if preferred.
