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.

Best value for hard water
Tefal Ultragliss Anti-Calc Plus FV6848
- Anti-scale: Removable scale collector
- Continuous steam: 50g/min
- Tank: 270ml
- Steam shot: 260g/min
The scale collector pulls out and rinses under the tap in about thirty seconds, so descaling actually gets done.
Best anti-scale filter
Tefal Ultimate Pure FV9845
- Anti-scale: MicroScale filter
- Continuous steam: 60g/min
- Tank: 350ml
- Steam shot: 260g/min
Its filter catches scale in the tank before it reaches the steam chamber, the most thorough system we found on a normal iron.

Best cordless for hard water
Morphy Richards easyCHARGE 303250
- Anti-scale: Anti-scale and self-clean
- Continuous steam: 30g/min
- Tank: 350ml
- Recharge: Under 25s
Expert Reviews picked this one out for hard water, and the 350ml tank means fewer refills of chalky tap water.
Best steam generator for hard water
Tefal Pro Express Vision GV9820
- Anti-scale: Removable scale collector
- Continuous steam: 180g/min
- Tank: 1.2L
- Pressure: 9 bar
Steam generators suffer most from scale. This one uses the same rinse-out collector as Tefal's irons, in the base.

- Anti-scale: Anti-calc system

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.
