The Real Truth About Water Softeners
Costs, benefits, running expenses & whether one is right for your home
By Towns Water Softeners – Tonbridge

Why we wrote this guide

Hard water is something most homeowners live with — often without realising how much damage it causes over time.

People usually come to us asking:

  • Do I actually need a water softener?
  • How much do they cost?
  • Are they expensive to run?
  • Is it worth it, or is it a gimmick?

This guide answers those questions honestly, without sales pressure, so you can decide if a water softener is right for your home.

Hard water contains high levels of calcium and magnesium.
In Kent and the South East, hard water is very common.

You’ll usually notice it through:

  • Limescale build-up on taps and showers
  • White residue on tiles and glass
  • Kettles and appliances failing early
  • Poor soap lather
  • Dry skin and hair

Limescale isn’t just unsightly — it shortens the life of plumbing and appliances.

A water softener removes the calcium and magnesium minerals from your water supply and replaces them with a very small amount of sodium.

The result is:

  • No limescale
  • Softer water throughout the home
  • Better performance from appliances
  • Easier cleaning
  • Improved comfort for skin and hair

The real benefits of a water softener

In your home

  • No more limescale on taps, tiles, or showers
  • Bathrooms stay cleaner for longer
  • Less time spent cleaning

For appliances & plumbing

  • Boilers, washing machines and dishwashers last longer
  • Improved efficiency (limescale reduces heating efficiency)
  • Fewer breakdowns

For you

  • Softer skin and hair
  • Less soap and shampoo needed
  • Towels and clothes feel softer

Many customers notice the difference within days.

Typical supply & installation costs

As a general guide:

  • £1,800 – £2,500
    Entry to mid-range softeners
  • £2,500 – £3,500+
    Premium, non-electric or high-capacity systems

The price depends on:

  • Size of the property
  • Number of bathrooms
  • Water usage
  • Type of softener (electric vs non-electric)
  • Ease of installation

We’ll always advise what’s suitable — not just what’s most expensive.

This is one of the most common concerns — and it’s usually less than people expect.

Running costs typically include:

Salt

  • Usually £80 – £150 per year, depending on usage and system type

Electricity (if applicable)

  • Electric softeners use a very small amount of power
  • Non-electric softeners use none

Servicing

  • Not always required annually
  • We’ll advise based on the system chosen

Most homeowners find the running cost is easily offset by:

  • Reduced cleaning products
  • Fewer appliance repairs
  • Longer appliance lifespan

Yes — with a caveat.

  • Softened water is safe to drink
  • However, many households choose to keep the kitchen cold tap unsoftened for drinking

For customers who want the best possible drinking water, we often recommend a separate filtered or RO (reverse osmosis) drinking water system alongside the softener.

This gives:

  • Softened water for the home
  • High-quality filtered drinking water at the kitchen tap

For most homes in hard water areas, yes.

They are particularly worthwhile if:

  • You live in a hard water area
  • You’re fitting a new bathroom or kitchen
  • You want to protect appliances
  • You’re fed up with limescale and cleaning

They may be less worthwhile if:

  • You’re moving very soon
  • Water usage is extremely low
  • Installation isn’t possible due to pipework constraints

We’ll always be honest if it’s not right for your situation.

Common myths about water softeners

“They’re expensive to run”
→ Usually not — running costs are modest.

“They’re bad for plumbing”
→ The opposite — they protect it.

“They’re complicated”
→ Modern systems are very simple.

“They don’t make much difference”
→ Most customers say it’s one of the best upgrades they’ve made.

How installation works

Most installations:

  • Take a few hours
  • Are completed in one visit
  • Cause minimal disruption

We’ll always check:

  • Available space
  • Water pressure
  • Pipework layout
  • Drain access
