No hassle. A qualified plumber comes to you, fits the filter under your sink, and you're set — same day.
Call or WhatsApp us to book. We'll confirm a time that works for you.
Our plumber arrives with everything needed. No trips to a shop, no waiting for deliveries.
Clean, professional installation under your kitchen sink. We test it before we leave.
Drink straight from the tap. No subscriptions, no plastic bottles, no running costs.
Why ClearFlow
Chlorine, limescale, heavy metals, fluoride. The filter handles it all before it reaches your glass.
The average London household spends £400+ a year on bottled water. One filter pays for itself fast.
We're plumbers. This is what we do. Neat installation, no mess, fully tested on the day.
Cut your plastic waste to zero. One filter, thousands of bottles saved.
The system
Every ClearFlow unit runs your water through five separate stages before it reaches your tap — each one built to catch something the last one missed.
Removes sand, rust and visible particles
Strips chlorine, odour and bad taste
Second-pass polishing for cleaner water
Blocks bacteria and microscopic contaminants
Last stage — pure, great-tasting water
