Systems we install and service
Under-sink drinking water filters
Multi-stage carbon or reverse osmosis with a dedicated tap — removes chlorine taste, sediment, lead and microplastics.
Whole-house filtration
Fitted at the mains so every tap, shower and appliance in the property receives filtered water.
Water softeners
Ends limescale in kettles, showers and boilers, and extends the life of your heating system.
UV and specialist treatment
For private boreholes and wells: UV disinfection, iron and manganese removal, pH correction.
How it works — from water test to filtered tap
Free water test
We test hardness, chlorine, iron and TDS at your tap and explain what is actually in your supply.
System recommendation
You get a written fixed-price quote with the exact system, flow rate, running costs and cartridge schedule.
Installation day
Isolation, bracketing, plumbing in, pressure test, flush and commissioning — usually two to four hours.
Servicing and support
Annual cartridge changes, sanitising and performance checks, with a 48-hour response if anything goes wrong.
Installed properly, built to last
Every installation uses WRAS-approved fittings, isolation valves either side of the unit and a bypass where the layout allows, so future servicing never means draining the house. Housings are bracketed to the wall, never left hanging on the pipework.
We pressure-test, flush and sanitise the system, then hand over the manual, the cartridge schedule and before-and-after water readings taken at your own tap.
Water you are happy to drink
No more chlorine smell, no more bottled water deliveries and no more scale ruining kettles, shower screens and boiler efficiency. Filtered water on tap for the whole household, from the first day.
Frequently asked questions
How much does water filter installation cost?
An under-sink drinking water filter typically starts around £390 fully installed, reverse osmosis from £690, and whole-house systems from £1,150. You receive a fixed written price after the free water survey.
How long does the installation take?
Most under-sink systems take about two hours. Whole-house filtration or a softener at the rising main usually takes three to four hours, and we leave the system flushed and ready to use.
How often do cartridges need changing?
Sediment and carbon cartridges are usually changed every 6 to 12 months, and reverse osmosis membranes every 2 to 3 years. We remind you before each service is due.
Is UK tap water not already safe?
UK mains water meets strict standards, but chlorine taste, hardness, lead from older pipework and sediment are common. A filter is about taste, limescale protection and peace of mind rather than replacing your supplier.
