If your kettle is brand new it should be boiled and refilled three times before use. If it is an older kettle descaling with white vinegar may help. To establish where the taste is coming from it may be worth making two hot drinks – one from your kettle and one using water from a saucepan and comparing the two. Water taste can be affected by many factors. It may be worth checking where there is an engineer currently working on your water supply - there may be a van outside. If you still suspect the taste is from your kettle and it is under the one year guarantee please contact the Customer Experience Department here.
