Water Softener Installation in London & Kent
Already bought your water softener? GX7's engineers install Harvey, Monarch, BWT, Kinetico, Water2Buy, Tapworks and other leading brands across South East London and North West Kent. Installation starts from £350 (labour only, softener supplied by you).
The final price depends on where the softener will go and whether new pipework, a bypass, drain or electrical connection is needed. Your price is confirmed before any work starts.

New Water Softener Installation
We install your customer-supplied softener (Harvey, Monarch, BWT, Kinetico, Water2Buy, Tapworks and others) with isolation valves and a bypass, so water can be turned back to normal if needed.
Water Softener Installation Services & Prices
Most of our customers buy their own water softener and we install it. Installation starts from £350 (labour only). Your price is confirmed before any work starts and depends on where the softener goes and what pipework or connections are needed.
Replacement Water Softeners
Replacement of existing water softening equipment where a new compatible unit is required.
Pipework & Connections
Where there's no existing set-up, we run the new pipework, drain and overflow connections, priced on your quote.
Hard Water Drinking Tap
Most manufacturers recommend keeping a separate hard water tap for drinking and cooking. We can fit one with your softener, priced on your quote.
Why Consider a Water Softener?
Less Limescale
Softened water greatly reduces new scale forming in your pipework, hot water cylinder and heating system.
Much of South East London and North West Kent has hard water. A water softener removes the calcium and magnesium that cause limescale, so less scale builds up in your pipes, boiler, taps and appliances.
Results depend on your local water hardness and the softener you choose. A softener doesn't remove existing heavy scale, and it isn't suitable for every property.
Protects Appliances & Fittings
Less scale on kettles, washing machines, dishwashers, taps and shower heads, which helps them keep working as they should.
Easier Cleaning
Fewer white marks on taps, tiles, glass shower screens and sinks, and many people find they need less cleaning product.
Better for Your Boiler
Scale in a boiler's heat exchanger reduces efficiency over time. Softer water helps keep it cleaner.
