Quick answer: in hard-water areas choose an iron with a removable scale collector or filter. The Tefal Ultragliss Anti-Calc Plus is the best value; the Tefal Ultimate Pure has the most effective anti-scale filter; and the Tefal Pro Express Vision is the best steam generator for hard water because its scale collector rinses in seconds.

Much of England, including London, the South East, East Anglia and the Midlands, has hard water. Limescale is the main reason irons start spitting, lose steam and fail early. The iron you choose matters, but so does emptying the tank after use and descaling regularly. See how to descale a steam iron.

Anti-scale systems explained
- Scale collector (Tefal): traps flakes in a removable cartridge you rinse under the tap. Easiest.
- Anti-calc filter: treats water in the tank before it reaches the steam chamber.
- Self-clean / Calc-Clean: flushes scale out through the soleplate. Effective but needs doing regularly.
- Anti-calc cartridges: replaceable, adding a small running cost.
Frequently asked questions
Which iron is best for hard water?
One with a removable scale collector or filter, such as the Tefal Ultragliss Anti-Calc Plus or Ultimate Pure.
Should I use distilled water in hard-water areas?
Only if your manual allows it. Many irons are designed for tap water or a tap/distilled mix; pure distilled water can cause spitting in some models.
How often should I descale in a hard-water area?
Roughly once a month, or whenever the reminder light appears.
