Best Water Softener – UK Buyer’s Guide & Review

Most residential locations in the UK suffer from a certain degree of hard water. This annoying problem leaves an accumulation of limescale on the surface of sinks, washbasins and bathtubs, and damages pipes and appliances like dishwashers, hot water dispensers and washer dryers.

Hard water is not only an issue for your laundry machine, but it also means you will wash your bathroom more frequently.

Sometimes hard, mineral-rich water can have toxins, so utilising the best water softener in the UK is crucial to keeping you and your family healthy. But which softeners do you go for?

This article focuses on the best water softeners in the UK, their features and the advantages and disadvantages of each product so that you can find the best water softener to suit your needs.

Eddy Water Descalers

Although technically not an electronic softener, the Eddy Water softener is a great option. Essentially, this water softener removes all the metal that would result in limescale without removing other healthy minerals and vitamins in the water.

The Eddy electronic water softener is very easy to install and also eco-friendly, meaning that it has a minimal effect on the environment. This softener ensures that limescale does not build up or damage your pipes. This method is cost-effective as it uses less electricity and requires no salt, however, it can be too mild if you want softer, highly purified water.

Compared to a regular water softener, it utilises a magnetic field to prevent lime from reaching showers and sinks. Although it does not remove the hardness of the water, it changes its composition so that the lime does not stick to any of the showers or sinks. This is to ensure that magnesium and calcium levels, which may have health benefits, remain relatively unchanged.

Tthis salt-free softener does not function well with lead conduits, so you may have to replace many of the connectors or find another solution that may be convenient.


  • Does not require salt, making it easy to use.
  • A healthier substitute to water softeners because minerals are preserved
  • More environmentally friendly method of dealing with lime and hard water
  • Cost-effective
  • Simple to install, so anyone could do it.


  • Does not function properly on lead pipes
  • Compared to a regular water softener, it does not remove as much limescale
  • Must be installed adjacent to a power source

It may be easily placed under the counter without taking up too much storage space. While it is still large enough to supply a large amount of softened water, a maximum of 1,250 litres per day, it is considered small compared to other water softeners from this company.

Water2Buy W2B500

If you are searching for a water softener that is suitable for a large family home, this Water2Buy model water softener system may be what you require. The W2B500 Water Softener is a self-cleaning water filter that can deliver up to around 1,415 litres of smooth, healthy filtered water every day. It is perfect for a 4-7 person home and is completely compatible with the majority of the British boiler systems.

So you will still be able to enjoy a revitalising hydro-massage shower without worrying about uncomfortable limescale. This intuitive system is designed to be cleaned at 3 am so it won’t interrupt your daytime schedule. The cleaning cycle is also incredibly quiet, perfect if you are a light sleeper.

While this Water2Buy water softening system is suitable for the majority of homes, setting the regeneration cycle can be a little confusing. Rewind, brine, and wash options can be challenging to correct. The manual is also not very useful and seems to contradict the data on their site.

Also, be very careful when filling the device, as the lugs on the top are quite thin and can easily break. The product comes with 3/4 ″ BSP fittings and 15 mm replacement fittings if needed. Please note that you might need to buy additional parts to set up the device to your current configuration.


  • Provides up to 1,415 litres of filtered soft water per day
  • Silent self-cleaning cycle at 3 am
  • Suitable for families of 4 to 7 people
  • Does not affect water pressure

Alternative AquaHouse NSWS

This AquaHouse salt-free water softener is the perfect if you are searching for a product to prevent limescale. It functions well for small to medium sized families and can be easily installed anywhere because of its size.

Once your plumber has installed this product and connected it to your cold water supply, it not only prevents contamination with 99.6% efficiency but also actively cleans the pipes to enhance water flow. You should note that this item is not compatible with warm water inlet conduits.

Since it is a salt and chemical free softener, it removes the “slippery and sticky” feeling you might experience with salt-based water softeners. Hence, this model is the right choice if you find this feeling unpleasant when utilising salt-based brands. Instead, it makes use of a process recognized as Template-Assisted Crystallization that breaks down the water hardness and changes it into minute crystals that can’t change or harm your water system. Lack of salt requirements means this device needs less maintenance and wastes less water, in addition to preserving the useful minerals in the water supply.

In terms of flow capacity, AquaHouse can support households where the water flow rarely reaches over 8 litres per 60 seconds. Although it can withstand a maximum flow of 20 litres, it is not advisable that this water softener undergoes this load for a prolonged length of time. So if you regularly require this flow level, you would be better off choosing a more powerful model. Although it provides a 3-year warranty on system mounts and parts, you should note that this warranty does not apply to filters.


  • Fabric softener free of salts and chemicals
  • Reduces wastage of water
  • Low maintenance
  • Descales pipes actively
  • 3-year guarantee for water softening in fixings and parts of the system


  • To make adjustments you will need a plumber
  • Not fit for hot water
  • The warranty does not cover the filters
