West London Water Softeners helps eco-conscious homeowners shrink their carbon footprint using TwinTec Cobalt units that save 84 tonnes of plastic waste yearly.

The low-cost installation options they offer fine-tune systems to match exact plumbing layouts, so upgrading your setup doesn’t trigger unexpected plumbing headaches.
Just be aware that running these systems causes a minor 1 to 3% drop in water pressure. Plus, living outside the main service network requires returning units directly to manufacturers for repairs.
Professional and efficient installation service
Installation of a TwinTec S4 water softener:
fter some comparisons I finally picked West London Water Softeners to provide and install the water softener.
I was given a competitive quote and needed advice about setting up a softener in a flat. The delivery and installation were done in a week from the order date. On the installation date, the work was completed with minimal nuisance in 2 hours, and my place was kept neat and tidy.
Nicholas was extremely helpful and friendly throughout. I would not be hesitant to recommend his company.

High quality, professional installation experience
I don’t usually leave reviews other than for food bu, but I was genuinely impressed with the service I received. From the first visit, Edward explained clearly without any pressure to go for best option.
The installation was quick, tidy, and very professional. Since having the water softener fitted, the difference has been noticeable straight away—less limescale, better water quality, and even things like washing up and showering feel better condition for my hair follicles.
Overall, a reliable and knowledgeable team who clearly take pride in their work. I’d happily recommend them to anyone considering a water softener.

2. The Italian Plumber

Address: 2 Printer’s Yard, 90a The Broadway
Contact: 0208 9 457457 | [email protected]
Hours: Monday to Thursday 8:00 AM-5:30 PM; Friday 8:00 AM-4:00 PM
The Italian Plumber simplifies solving harsh mineral buildup by drawing on over 15 years of local expertise to give completely unbiased system advice. Their recommendations ensure you don’t end up paying for unnecessary upgrades.
They’re proud to be Gas Safe, and their Water Regulations Advisory Scheme (WRAS) certifications guarantee every fitting meets strict safety codes.
Another thing we appreciate is their no-obligation home surveys, so they can plan the right and totally stress-free setup for every property.
Their transparent pricing models eliminate sneaky travel fees so final installation costs remain clear and predictable, too.
One thing to note is that supplied parts carry a 25% markup on trade prices plus VAT. Extra charges for parking can also pop up on your bill, so confirming total costs beforehand keeps your plumbing budget on track.
Excellent plumbing and heating installation service
Samuel and team did a great job implementing a high pressure tank and pump and system in my house to increase pressure in all showers, upgraded my underfloor heating system to use quieter variable flow pumps and also made my water softener system more secure. Delivered on time, on budget and always courteous and friendly. Highly recommended

Excellent plumbing and heating installation service
Contacted the Italian Plumber for advice on water softeners. They provided a quote, but when I asked why they recommended a softener that doesn’t use salt, they said it was a technical question their engineers couldn’t answer and advised me to contact the manufacturer directly.
Editing this review as Samuele has responded to me and given me a lot of time to go through options

3. Waterways

Contact: 0208 146 3000 | [email protected]

Waterways helps clients protect rental units from harsh limescale damage by relying strictly on dedicated in-house staff. Their tailored recommendations start with thorough pipework surveys, ensuring the setup will exactly match your budget.
I love that they repair major brands at the Minimax Hub within three weeks. This team also does direct quality control, making sure that a property won’t turn into a headache with unpredictable issues over time.
Beyond that, their interest-free payment plans keep initial costs low.
On the other hand, checking an older unit requires a non-refundable inspection fee. Replacement parts for obscure or outdated models aren’t always available either, so confirming system details upfront avoids frustrating delays.
Smooth installation and great results
Had my soft water system installed 2 weeks ago and couldn’t be happier. The installation process went smoothly from start to finish, and the plumber walked me through every step, answering all my questions. Living in a hard water area, I’ve already noticed a real difference throughout my home—softer water, cleaner appliances, and better lather from soaps. Great customer service and a hassle-free experience. Highly recommend Water Ways for anyone considering a softener!

Amazing results after two weeks
Just had my water softener installed today after seeing Waterways recommended on NextDoor. Initial visit and follow up calls were great. Very smooth process and installation today. Cant wait to see & feel the difference. **Update** After 2 weeks the difference is amazing. The taps, shower glass etc just stay clean, no water marks.

London Water Filter gives homeowners complete confidence by operating as London’s only installer with direct Waterdrop authorisation.
Their equipment and manufacturer warranties ensure you don’t face unexpected breakdowns or worry about fake parts.
They handle installation at no extra cost, testing Total Dissolved Solids levels before and after setup to provide clear written proof. Their high-performing winTec S4 models come backed by solid warranty coverage, too.
Additionally, they conduct purity testing for their clients so they can enjoy clean, fresh drinking water directly from their tap straight away.
Just a heads up: their physical showrooms aren’t open yet, so browsing and purchasing happen entirely online. Also, service areas are strictly limited to the 33 London boroughs, meaning properties outside that boundary aren’t covered for installation.
Efficient service and quality improvement
Very efficient and good communication and advice. I had a water softener for the flat and then a 3 stage filter under the sink, water quality is significantly improved and I have peace of mind that the work is good quality.

Phenomenal installation and professional team
Leo, Mario, and the team did a phenomenal job installing our water filter and softener system. They started with a thorough assessment and knew exactly what our home needed.
We ran into a few early hitches with a faulty manufacturer part, but this is where the guys really shined. No excuses, no deflecting. Leo and his crew stepped up, handled the issue professionally, and communicated clearly until everything was running perfectly. They also kept the workspace clean and respected our property.

5. UK Water Softeners

UK Water Softeners takes the stress out of upgrading your home’s water supply by providing completely free, no-obligation site surveys.
These clear expert assessments ensure you don’t waste cash on mismatched equipment or unnecessary plumbing alterations.
When you hire this company, installers with over 35 years of experience fit highly efficient, non-electric twin-cylinder systems tailored to your pipework. Plus, their 10-year parts warranties protect long-term investments.
I also like their convenient doorstep salt delivery options, which keep maintenance completely effortless without heavy lifting.
That said, their free salt deliveries apply only within specific local zones. Standard online orders can also take up to 10 working days to arrive.
Thus, ordering supplies early prevents running out during busy weeks.
Friendly, efficient, and helpful service
We bought a water softener from UK Water Softeners – they were recommended through Check-a-trade. Buying though them was a great experience – Sarah provided quotes and described everything really well and Steve did the install very smoothly and efficiently. They were both very friendly and helpful and I’ll definitely be buying from this local team again.
We opted for the TwinTec S4 to replace an old system that came with the house – so far it seems to be doing a much better job than the old system.

Exceptional, meticulous, and professional service
What a lovely local British company. Our 20 year old water softener was noisy. I made the call for an inspection. The engineer Andrew is such a nice gentlemen. He was very patient when discussing the options on what to do next and gave me the time to make up my mind without hurrying me..
Very conscientious and his work is of such a high standard. Meticulous detail. Took a lot of trouble routing the new pipes.
Amazingly our original water softener was supplied by Andrews dad Kevin Goody. This is such a nice local family concern. Deserve our support.
