How much money can I save with a water softener?

If you are based in a hard water area, there are plenty of reasons to install a water softener in the home, the main reason being to save money. By process of ion exchange, the water softener will draw out the magnesium and calcium ions, the mineral content which makes it ‘hard’ in the first place. Having soft water flowing through your household will limit the accumulation of scale and scum and will actually provide treatment to areas where it has formed. You will also notice the water feels different, smooth and silky on the skin providing much more effective washes when combined with soap and washing detergents.

These are the benefits to your household, the things you will notice immediately. Gradually, you will also find yourself saving a lot more money. 

Simple ways to save water

  • Wash vegetables in a bowl, not under a running tap 
  • Don’t use ‘half-load’ programmes on your washing machine – these don’t save much water and its much more efficient to wash a full load each time
  • Keep a bottle of tap water in the fridge – this saves you running the tap until it’s cold every time you want a drink 
  • Shower rather than bathe – a five-minute shower uses a third of the water of a bath
  • Fix dripping taps – a dripping tap can waste up to 15 litres of water a day (it’s quick and easy to replace a worn-out washer)
  • Fit a water-saving device in your toilet cistern – you can get these for free by contacting your water company. If you’d rather not wait, just put a standard two-litre water bottle in there, with sand or pebbles as ballast
  • Turn off the tap while brushing your teeth – this wastes a lot of water unnecessarily
  • Use water wisely in the garden – watering your plants while it’s cool reduces water lost to evaporation, and you can add organic matter to your soil to improve water retention


Soft water is a solvent meaning it can dissolve other chemicals easily. Due to hard water’s mineral content, the water is more inert or less capable of sustaining a reaction. When combined with soap, it won’t create a proper lather leading to you having to waste more and more detergent just to get an effective clean. With soft water you can use a fraction of the amount and still gain a better clean, that will preserve the fabrics of your clothes.

Energy Sales

The average household in a hard water area, will gain at least 1.5mm of scale building within its internal plumbing over a year. Scale is an insulator and will transfer the heat of your system less effectively. A buildup of just 1.5mm is enough to reduce your heating efficiency by at least 12%.

Again the following figures are provided on the basis of an average family home belonging to two adults and two children.

Item Cost Saved
Fuel Saving £7.80
Capital Depreciation £13.43

This represents a saving of at least £240 on your heating bill over one year. In addition, softened water is expected to preserve your boiler’s life span to the standard 15 years.

Installing a water softener acts as a long term investment, that will save you greater amounts of money over the years. The favourite non electrical twin cylinder water softening unit contains no moving parts, it works automatically and is able to cope with the larger demands of water in the family home. All you need to do is add salt, in the form of block salt that costs as little as £7.58 a month.

Independent studies have been undertaken to quantify greenhouse gas reduction through the use of a water softener. One such article concludes that water softeners and RO units together will reduce greenhouse gases equivalent to getting one and a third cars off the road for an entire year!

We also have studies showing just how the efficiency of a boiler will drop with just a small amount of scale build up. A water softener will remove all scale from your heating system and prevent any future recurrence, allowing your system to function as it was designed to do.
