Preventing limescale in kettles is a high priority for the population of Britain. With a history of tea lovers, having a consistently good cup of tea or coffee is an issue we have been tackling for years. Limescale affects the taste of the water coming from a kettle, even after the water has been boiled. It is highly common with roughly 14 million UK households suffering from the impact of limescale. 87% of respondents to Harvey’s 2020 customer survey said that limescale was the most frustrating thing about hard water.
