We install water softener systems across Croydon — from town-centre flats to the chalk-water areas of Purley, Coulsdon and Selsdon — removing hard water, reducing limescale build-up and protecting your boiler and appliances. Supply and install, or install-only if you’ve already chosen your system. Fixed price, clean installation, all CR postcodes covered.

Croydon’s southern areas sit on the North Downs chalk belt that runs through Purley, Coulsdon and Kenley, giving much of the borough some of the hardest mains water in South London. Here are the four most common and costly problems it causes.
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.
Often sludge build-up restricting flow — common in older Sanderstead and Thornton Heath systems that haven’t been power flushed in years.
Washing machines, dishwashers, electric showers and combi boilers in Croydon’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 Croydon 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 Croydon's mix of flats and larger houses.
For supply and install bookings, we recommend the right capacity and regeneration type for your property size and Croydon'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 Croydon'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 Coulsdon and Purley properties.
Washing machines, dishwashers, showers and boilers all last longer on softened water — most manufacturers recommend it in hard water areas like Croydon.
New radiators fitted and the whole system rebalanced so every room heats evenly, not just the nearest to the boiler.
Descaling products, replacement showerheads and early appliance replacement are recurring costs in Croydon's hard water postcodes — a softener removes the cause, not just the symptoms.
Costs vary by bathroom size, chosen fittings, and the extent of any structural or layout changes. All prices are fixed and agreed before work starts.

Fast arrival across all Croydon postcodes without the delays of London-wide dispatch, from Croydon town centre to Purley and Coulsdon.
Water softener installation must comply with WRAS and Water Supply Fittings Regulations, including bypass valve, air gap and backflow prevention — done correctly on every job.
Coulsdon and Purley contain a number of larger, older properties with longer pipe runs. Our engineers plan installations that keep pressure and flow consistent throughout the house.
Same pricing whether you're in CR0 Croydon town centre or CR8 Purley.
We supply Harvey, Kinetico, BWT and other leading systems, recommending based on your Croydon property and water hardness — not brand preference.
All water softener installation work in Croydon 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.”
“Big old house in Coulsdon with terrible 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 Purley flat. Explained the bypass and salt settings clearly and the job was done in under three hours.”
Yes. We cover the entire Croydon borough — CR0, CR2, CR3, CR4, CR5, CR6, CR7, CR8 and CR9 — including Croydon town centre, Purley, Coulsdon, Selsdon, Thornton Heath and Addiscombe, with no zone surcharge.
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. Croydon's southern areas sit on North Downs chalk, giving mains water in the 280–380 mg/l (as CaCO₃) range — classified as very hard. This affects Purley, Coulsdon and Kenley in particular.
Yes. Our engineers regularly work on larger properties with longer pipe runs, sizing the system correctly to maintain consistent pressure and flow throughout the house.
In Croydon'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.
