Water softener FAQs

Do I need a water softener?

If you live in a hard water area (London, Hertfordshire, Essex, much of the south east — all hard) and see limescale on kettles, taps, showers, or inside appliances, a softener pays for itself in appliance lifespan, boiler efficiency, and reduced cleaning. Hertfordshire and North London are particularly hard water areas.

How much does installation cost?

£300 to £800 plus VAT depending on softener size, brand, and installation location. Includes mains isolation, new bypass valve, drain connection, and commissioning.

What softener brands do you fit?

Kinetico, Harvey, BWT, EcoWater, TwinTec, Monarch, Tapworks. Electric and non-electric models. We help choose based on household size, water hardness, and budget.

Does it need maintenance?

Yes — refill with softener salt every 4-6 weeks (typical family home). We can also service annually to check valves, resin bed, and efficiency.

Is there a call-out fee?

No. Standard call-out and travel always included.

Do you guarantee the install?

1-year parts guarantee on everything we fit. Plus the manufacturer warranty on the softener itself (varies by brand, typically 2-10 years).
