We do any size property so if in any doubt about what you need, don't worry, please contact us to discuss and confirm your requirements.


Please note this unit only softens but does not filter your water.

This is because water softeners are not water filters. Unlike filters, softeners don't improve the taste of the water.

So if you only have a water softener you will still be drinking and bathing in chlorinated water.

You can now combine your water de-scaling with a powerful Whole House water filter - that will remove unpleasant tasting chlorine and greatly improve the quality of your drinking AND bathing experience.

For a limited time, if you buy your highly effective new salt-free softener and the powerful Whole House water filter together you can save £100 - for the next few customers only

(The usual price is £697 - Our special offer price is £597 - all inclusive).

Replacing the Filter Cartridges

Economical - Cartridges cost £147 to replace and last for 2 years.

Replacement Cartridge Code: SC16

You can order a spare cartridge here

Inlet / Outlet - One inch BSP Brass Female


Note: re Changing Filter / Clearance Room Under the Unit

If you have a tight space make sure to allow some clearance room underneath the fitted unit for changing the filter.

You need a minimum of 5cm / 2 inches inches below the white bowl for it to drop down and slide away.



You can get a plumber or handyman to install the unit - this should take about 1 hour. Or you can DIY if you know how to cut a copper pipe. Inlet / Outlet - One inch BSP Brass Female as standard.

For full installation instructions click here


Water storage tanks?

We have a water storage tank. We want to put the softener before the tank. Will the fact the softened water sits in the tank for a while have any effect?


For all practical purposes the answer is no.... 

If we had to give a time it would be days and weeks rather than hours but there are so many factors influencing this that is impossible to be specific without a full knowledge of the water chemistry.

But let's take a hypothetical "even if it did" position....even if it did, it would only affect the stored water and any in pipes etc down stream. Even if it did, and some scale formed - as soon as the water began to flow as normal again, the freshly treated water would mitigate any minimal scale build up that may theoretically occur by acting against it and clearing it out.

Sorry that we can't be more specific, but...for all practical purposes the answer is no.

Ratings & reviews

really improved water quality - Review by Martin
The water filer is doing its job so far. We are in a horrible water area and it has kept the washing machine clear and less fur on the kettle. There has been no issues and this is our second filter. The filter doesn't clog up at all so it is great.
We are in a high chlorine area and the water has really improved with the filter.
really impressed - Review by Paul
I received it in excellent time. I ordered it well in advance as I like to have a replacement here just in case… I will be fitting it in the next month.

Thank you to everyone for all their support and advice- I was really impressed at the friendly customer service, efficient sales support and promptness of delivery.
very impressed!!! - Review by Margaret
just as good as the salt softener that we had before, but not even half the hassle.
brilliant - Review by Phil
I installed one of these in my house last summer and isolated the salt softener. Brilliant - there has been practically no build up of scale in our kettle since when previously it would be heavily scaled up within a couple of months!
Good product - Review by Ash
Have installed this since 2 weeks seen difference in lime scale reduction. Dishwasher is spotless no marks on utensils. I only gave it 4 star because of the size could be smaller. Customer service of company is very good.
Very impressed... - Review by David
Very impressed with the ordering process and rapid delivery. The filter has been fitted by the plumber in our house which is being renovated so we are not living there yet. He hadn't seen one of these before but said he was able to fit it quite easily.
Excellent service - Review by Mel
I have recently purchased three water filter systems from UK Water Filters and am more than pleased with their service and attention to the queries I put to them, their promised to delivery date was kept and I will certainly deal with them in the future.
Great buy - Review by Frank Speake
Feels and acts like soft water. A vast improvement. Would recommend this product.
