What moves the price
- Type of water softener — a whole house unit costs more to buy and fit than a compact under-sink model.
- Complexity of the installation — a softener placed far from the main water line needs a longer pipe run and more fittings.
- Any additional plumbing modifications required — fitting a bypass valve and a drain connection for the softener adds parts and time.
- Size of your home — more bathrooms and occupants call for a higher-capacity water softener, which costs more.

How to pay less
- Fitting the softener close to where the main water line enters the house keeps the pipework short and the installation simpler.
- Choosing a unit sized for your household's water use, rather than the largest capacity, keeps the cost of the water softener down.
- If you only want softer drinking and cooking water, an under-sink water softener costs less than a whole house system.
- Booking the water softener installation alongside other plumbing work, such as a kitchen or bathroom refit, avoids a separate call-out.
- Keeping the salt topped up helps the water softener run as it should, putting off the cost of repairs or a replacement.
Before you book

- Information about the current water hardness and any existing plumbing issues.
- Space for the water softener installation, typically near the main water line.
