Brilliant Plumbing installs water softeners across the London Borough of Richmond upon Thames — protecting boilers, pipework and appliances from the hard water that affects most of South West London. Whether it’s a Georgian townhouse in Richmond, a riverside conversion in Barnes, or a family home in Teddington or East Sheen, our engineers size and fit the right softener for your property, at a fixed price, with a 12-month guarantee.

Richmond upon Thames sits within South West London’s hard water region, drawing on the same chalk-influenced supply as much of the capital. Combined with the borough’s mix of period plumbing in Georgian and Victorian townhouses and space-constrained flats, limescale is one of the most common underlying causes of appliance and heating problems we’re called out for.
Larger period properties with older pipework and heating systems are especially prone to scale build-up on heat exchangers over time. A softener fitted at the mains supply protects the whole system, not just individual appliances.
Older pipework in Barnes's riverside conversions can already be narrowed by decades of scale build-up. A softener slows further scaling and helps protect newly replaced pipework and appliances.
Family-sized properties in Teddington and East Sheen benefit from whole-house softening to protect washing machines, dishwashers and kettles as well as the heating system — reducing appliance wear and limescale on fittings.
Compact under-sink softener units are a practical fit for flats around Kew and St Margarets, where a full-size unit may not suit the available space. We advise on the right format for the property during survey.
Hard water causes gradual, cumulative damage that’s easy to overlook until it affects a major appliance or the boiler itself. Our engineers assess your water hardness and system before recommending a softener.
White, chalky deposits build up on fittings and glass shower screens, requiring regular descaling to keep them clear.
Scale build-up on the heat exchanger forces the boiler to work harder for the same output, increasing energy bills over time.
Washing machines, dishwashers and kettles are especially vulnerable to scale build-up on heating elements, shortening their working life.
Hard water can leave skin feeling dry after washing and laundry looking greyer and feeling stiffer than expected.
Scale narrows internal pipe diameter over years, gradually reducing flow and pressure throughout the property.
Kettles, coffee machines and shower heads needing descaling every few weeks is a clear sign a softener would help.
Standard softener installations are typically completed within two hours. Larger units and non-standard pipework configurations are quoted after a brief assessment.

All standard cleaning and single-section repairs are fixed-price, confirmed before work begins — no call-out charge. 12-month workmanship guarantee on every job.
A complete installation, from choosing the right system to a fully tested.
We check your water hardness, mains pressure and available space to recommend the right size and format of softener for your property.
Your engineer confirms the fixed price for supply and installation before starting. No work begins until you're satisfied.
We fit the softener at the mains with a bypass valve, connect it into your existing pipework, and keep the installation area clean and tidy.
We test the system, check for leaks, and talk you through salt top-ups and basic maintenance before we leave.
From compact under-sink units for Kew flats to whole-house systems for Richmond and Twickenham townhouses, we recommend the format that actually fits the space and household size.
Standard softener installations are usually completed in under two hours, with minimal disruption to your water supply.
The same fixed pricing applies whether you're in Richmond or Hampton. No zone uplift, no call-out charge, ever.
We only fit softeners from reputable manufacturers, backed by our 12-month workmanship guarantee on the installation.

“Constant limescale on every tap and shower head in our Richmond townhouse, and the boiler was starting to sound like it was working harder than it should. The engineer fitted a whole-house softener and explained exactly how to maintain it — noticeable difference within a couple of weeks.”
“Old pipework in our riverside conversion in Barnes was clearly suffering from years of scale. Softener installed cleanly under two hours, with a bypass valve fitted so we can still use the outside tap unsoftened for the garden.”
“Small kitchen in our flat near Kew didn’t leave much room, so the engineer recommended a compact under-sink unit instead of a full-size softener. Fits perfectly and does the job.”
Yes. We cover the entire borough including Richmond, Twickenham, Teddington, Barnes, East Sheen and Kew — postcodes TW1, TW2, TW9, TW10, TW11 and TW12. Our engineers are based locally across South West London for fast response throughout the area.
Ongoing maintenance is minimal — topping up the salt every few weeks depending on household usage. We talk you through this at installation, and offer a standalone servicing visit if you'd prefer it checked periodically.
Same-day across TW1, TW2, TW9, TW10, TW11 and TW12. Fixed price before we start. 12-month guarantee on every job.
