How much does it cost to boil a kettle?
According to Npower, a kettle costs around 2. 5 pence to boil. They say: “The average kettle holds 1. 5 pints and uses about one unit of electricity to boil 12 pints of water (or 8 x 1. 5 pint-full kettles) – so that’s around 2. 5p every time you boil a full kettle. ”
