The basic function of electric kettles remains unchanged, but the technology within them is evolving. Improvements include better insulation to keep water hot for longer, reducing the need for reboiling, and different temperature settings to suit various hot drinks.
Some modern kettles also feature filters and concealed elements to help prevent scale buildup. When replacing an old kettle, consumers may find options that offer significant differences in design, weight, ease of maintenance, and build quality.
Among the kettles tested, the Kenwood Ripple kettle offers a low minimum fill of 200ml, allowing for single-cup boiling and potentially better energy economy. The Dualit Classic kettle is highlighted for its repairable nature, with a replaceable 3kW element designed to extend the appliance's life.
Energy consumption for kettles has been assessed using a power meter, with costs calculated based on the Great Britain price cap from 1 October to 31 December 2026.
