Softer water, happier home.
Gentler on your family's skin, kinder to your appliances and no more limescale. We install and service water softeners, reverse osmosis, under-sink filters and UV systems across London and the Home Counties.
London's hard water is full of calcium and magnesium. Taking it out changes how your water feels, how your home looks and how long your appliances last.
Soap, shampoo and shower gel lather properly in soft water, so you use less and rinse cleaner.
Soap rinses off properly in soft water, so less residue is left behind. Many people say their skin feels less dry.
Cleaner, scale-free water protects washing machines, dishwashers, kettles, showers and your boiler.
Scale on heating elements makes them work harder. Without it, appliances heat water more efficiently.
Say goodbye to chalky taps, cloudy shower screens and scale around the plughole.
Towels stay fluffy, clothes stay brighter and hair feels softer and shinier.
Softened water is not a medical treatment. Speak to your GP about any skin condition.
Most of London and the South East has some of the hardest water in the UK. Hard water leaves limescale on taps, showers, kettles and inside your boiler, which pushes up energy bills and shortens appliance life.
We'll also estimate how much sodium your water would contain once softened, so you can think about the right drinking-water set-up. It's a rough guide to what's typical for your area: for exact figures, check with your water supplier.
Just the first part is fine, e.g. W4.

A softener works by swapping the calcium and magnesium in hard water for sodium. The harder your water, the more sodium is added: roughly 46 mg/l of sodium for every 100 mg/l of hardness removed.
Add that to the sodium already in your supply and, in very hard areas, fully softened water can go over the 200 mg/l limit for drinking water. It's also not recommended for making up baby formula. Every home is different, so we check yours and design around it:
From whole-house softening to drinking-water filtration at the kitchen tap, supplied, fitted and serviced by our own engineers.
Whole-house softeners that remove limescale from every tap, shower and appliance. Silkier skin and hair, sparkling bathrooms and a more efficient boiler.
Filtration for your kitchen drinking water. Reduces chlorine and chemical tastes and odours for better-tasting water, tea and coffee.
Multi-stage reverse osmosis for the purest drinking water. Removes sodium, dissolved solids and impurities at a dedicated kitchen tap.
Ultraviolet sterilisation that neutralises bacteria and viruses without chemicals. Handy for private supplies, storage tanks and anyone who wants an extra safety step.

“Placeholder review. The engineer was tidy, explained everything and the limescale on our shower screen has gone.”
“Placeholder review. The RO tap under the sink makes the best-tasting water. Quick, friendly install.”
“Placeholder review. Booked our annual softener service online and they confirmed the same day.”
Straight answers to the questions we get asked most on survey visits.
They're both sold as the answer to limescale, but they work in very different ways. Here's a fair, plain-English comparison to help you pick the right one for your home.
Read the guide →Salt, water, a bit of electricity and a yearly service. Here's what actually goes into a softener's running costs, how to work out your own, and how to keep them down.
Read the guide →Limescale creeping back? Salt not going down? Before you book a call-out, run through this checklist. Plenty of softener problems are a five-minute fix.
Read the guide →Yes. Most of London and the South East has hard or very hard water, typically 250–300+ mg/l of calcium carbonate, because the water passes through chalk and limestone. Use our postcode checker above to see an estimate for your area.
A water softener treats the whole house, removing the calcium and magnesium that cause limescale. A filter, such as an under-sink carbon filter or reverse osmosis unit, treats drinking water at one tap to improve taste and remove impurities. Many homes have both.
Most standard installs are completed within a day. We'll confirm timings after your free survey.
We usually recommend keeping a hard-water drinking tap in the kitchen, or adding an under-sink carbon or RO filter for drinking water. We'll talk you through the options.
We recommend an annual service for softeners, RO and UV systems. Carbon filter cartridges are typically changed every 6–12 months depending on usage.
Yes. We service and repair all major brands of softener, RO and UV system.
