Water softener

Best Water Softeners for the Home (UK)

A water softener can make a huge difference to the comfort of your household, especially when you live in an area with particularly hard water!

Think of how much easier life would be without the constant build-up of limescale, the roughness on your skin, and the expense of replacing electrical appliances like kettles before their time.

A water softener passes hard water through a cylinder that contains ion exchange resin, which attracts and retains the hardness minerals and leaves only the soft water to flow through your pipes.

All that’s needed to keep these machines running smoothly is a bit of salt.

There is a useful app that will efficiently guide you through the set-up process, but you will need the installation kit in order to get the machine set up properly.

This installation kit is sold separately, and many users have commented that it is both expensive and not particularly user-friendly.

Several users also mentioned that the machine appears to be using the salt much too quickly, which can cause costs to accumulate quite swiftly.

How to Narrow Down Which Water Softener Is Best for You

Narrowing down the many water softener choices can be a challenge, but the various options on our list are each unique and have very different things to offer.

Whether you’re looking for a lower price point or a smaller and more compact machine, there will be an option here for you.

Want an option that is more sustainable?

If you are looking for a water softener that uses salt but is more sustainable then the Monarch Midi FreeFlow water softener is the best option for you. This machine uses 12% less salt than similar products and is quick to regenerate.

If you’re looking to move away from salt completely then your best option would be the Little Plumber LP1 water softener, which uses low-frequency radio waves to remove the limescale from the pipes. This machine is long-lasting and doesn’t require much electricity to function.


Looking for the lowest price?

Water softeners can seem very pricey when you first look into them, but when you really think about it, they can be a real investment. Without limescale, your appliances are likely to last much longer, and you’d spend much less money on cleaning products!
